This is our day... let’s make the most of it

Not long now until the inaugural World Refrigeration Day on 26 June.

It’s been great to see support growing for the event, with a WRD Pavilion at the Temperature Controlled Storage & Distribution Exhibition in Peterborough and an open day of celebration planned at the Practical Refrigeration Training Centre in Burnley.

Even if you can’t make it along to an organised event, use the occasion to add up just how many times refrigeration (in its many varied forms) touches our daily lives.

And don’t keep it to yourself. Within this issue, Ed Whinyates of WRD sponsors Stonegrove looks at just a few of the ways refrigeration changes the world for the better and asks if the industry is underselling itself.

The simple answer is yes, and 26 June offers us all the opportunity to redress the balance.

Feel free to amaze your family and friends with as many fascinating refrigeration-based facts as you can muster. After all, it's only once a year.

Enjoy the magazine... and the summer!

Precision IT cooling with Mitsubishi Electric s-MEXT Mitsubishi Electric has launched its first packaged computer room air conditioning (CRAC) unit.

The manufacturer is keen to extend its IT cooling offering with the new s-MEXT high precision systems, which connect directly to Mitsubishi Electric’s DX Mr Slim Power Inverter outdoor units to create a full inverter split system.

The s-MEXT is the first Mitsubishi Electric Hydronics & IT Cooling Systems (MEHITS) product to certified with the company’s 3 diamonds, taking advantage of more than 50 years of experience of the RC brand within the IT cooling market.

Richard Venga, senior product manager at Mitsubishi Electric, said: “By using our Mr Slim Power Inverter system, our installers are already familiar with not only the system but with the installation process. Therefore, the s-MEXT can be installed quickly and efficiently, without the need to go through time-intensive training. It also means that the Mitsubishi Electric quality is assured as we roll out our first three diamonds-certified IT cooling product. We are excited to be offering the market a product that is familiar, flexible and reliable.”

The units are available in capacities from 6kW up to 42kW and are aimed at applications where high sensible cooling and close control of temperature and humidity are required, such as small and medium sized businesses (enterprise data centres) with IT cooling requirements. They are also available in both upflow and downflow variants.

AIRMASTER PROMOTES EX-APPRENTICE TO DIRECTOR Former apprentice Gareth Campbell has been promoted to contracts director by South Yorkshire-based mechanical services company Airmaster. Many members of the Airmaster workforce began their careers as apprentices, including founder director Richard Pogson and five of his six senior management team.

Gareth Campbell became Airmaster’s first apprentice in 2000 when chairman Tony England joined to enable the next phase of growth.

He said: “I joined Airmaster at 16 years old. I couldn’t wait to put my school years behind me and start using a hammer and any powered machinery I was able to get my hands on! Airmaster supported me to get on and encouraged fast learning and getting ‘stuck in’, which has taken me from tool-passer to contracts manager and now director. With hard graft, I’d say anyone has the opportunity to move their career forward at Airmaster. Coupled with great people, it is what makes it a fantastic place to work.”

Airmaster MD Lisa Pogson said: “We are all really proud of Gareth.

Nineteen years ago he was an apprentice, now via different roles and learning the key aspects of the business, he has become one of our directors. What a great achievement for him - it just goes to show that hard work, dedication to quality and the expertise our team of brilliant staff offer all our clients really does pay off.”

CUSTOMISABLE CONTROLLER FROM TOSHIBA Toshiba's new mini-touchscreen air conditioning room controller enables clients add their own branding and corporate messages.

The unit operates on the same principles as a high-end smartphone and is designed to be easy to use for end users and quick and simple to install for contractors. It uses the same two-wire connectivity as a standard controller, enabling it to be quickly installed without adding an external power supply on new projects and as an upgrade on existing systems.

The colour interface can be customised to match room décor, with 30 contrasting backgrounds available to create different moods or

June | July 2019

News.indd 6

messages. Clients can also customise the interface with their own corporate images, colours and logos by uploading images via the unit’s built-in USB connection.

David Dunn, TCUK’s managing director for sales, said: “Wall-mounted room controllers in hotels and offices are the vital interface between the user and the air conditioning system.

However, their design has not kept pace with changing user needs and expectations – often having complicated interfaces that confuse end users and make them difficult to use.

“Recognising the problem, we went back to the drawing board and asked clients: ‘What do you want from a wall controller?

How can we make it as easy to use as possible, and be a stylish addition to a room?’ We took the findings and came up with a completely new approach to room controller design.”

BESA PAYS TRIBUTE TO GRAHAM MANLY The Building Engineering Services Association (BESA) has paid tribute to its former president, Graham Manly OBE, who died last month.

The association said he was “an absolute gentleman and unifying figure, who leaves a huge legacy and whose death will be mourned right across the building engineering sector”.

Graham was one of the few people to have served as president of both the sector’s main contractor body BESA (then the HVCA) and its chartered institution CIBSE. He was also chairman of the industry’s research organisation BSRIA and was appointed an Officer of the Order of the British Empire (OBE) in 2012 for his services to building engineering.

“The world of building services has lost one of its most influential and best loved figures,” said current BESA president Tim Hopkinson. “He said himself that the greatest highlights of his career were related to people rather than buildings and that he was inspired by his father’s example to always treat people ethically and with respect. As a result, I can’t think of anyone who made so many genuine friends through their business dealings.”

Graham Manly was chairman of BSRIA in 1991/93; president of CIBSE in 2004/05; and president of the HVCA in 2009/10. He was also a director of Summit Skills and chair of the National Skills Academy for Environmental Technologies.

ADANDE REACHES NEW HEIGHTS IN NEW YORK Refrigerated drawer units from Adande have been installed at the Wild ink restaurant and bar at the newly developed Hudson Yards on Manhattan’s West Side in New York City. The 5,800 sq ft restaurant and bar is on the fifth floor of 30 Hudson Yards which, at 1,296 feet, is the second tallest building in New York.

Wild ink is owned and operated by Londonbased rhubarb, a provider of luxury culinary events at a variety of iconic arts, sporting and transport hub venues, as well as at a rapidly growing number of proprietary restaurants in and around London. Wild ink is rhubarb’s first venture outside the UK, but the company will be opening a second hospitality destination at Hudson Yards later this year.

Adande supplied 10 of its patented VCS2 refrigerated two-drawer units, which feature insulated horizontal container technology for stable holding temperatures and energy savings of up to 60%. The dual temperature modules may be switched between chilled and frozen storage temperatures, at the flick of a button, providing cold storage flexibility.

Karl Hodgson, global sales director at Adande, said: “This order represents further progress for Adande in the US market, where we have been targeting both foodservice and food retailing operators. We will continue to build on partnerships with customers in the US, who have embraced our innovative refrigerated drawer technology.”

MEHITS makes low GWP choice MEHITS, part of the Mitsubishi Electric Group, has chosen low GWP Opteon XL41 (R454B) and XP10 (R513A) refrigerants from Chemours for chillers and heat pumps.

MEHITS selected A2L refrigerant XL41 to replace R410A for its multiscroll platform. It offers a GWP of 466 and also reduces CO2 emissions by almost 80% when compared to R410A, while providing improved energy efficiency and similar capacity.

XP10 (X513A), chosen for the screw and centrifugal oil-free platform, is a non-flammable A1 azeotropic refrigerant alternative to R134a with a GWP of 631, making it an ideal replacement at 50% less GWP when compared to R134a.

Diego Boeri, vice president of Chemours Fluorochemicals, said: “We are proud that MEHITS chose Chemours and Opteon XL41 and XP10 for its chiller and heat pumps.

"This collaboration will help the chiller and heat pump industry move towards more environmentally sustainable refrigerant solutions while meeting long-term regulatory requirements and delivering consistent performance.”

Transport Meanwhile, Chemours has announced that it is working with Carrier Transicold Europe to specify and adopt a low GWP refrigerant to replace R452A in transport refrigeration in 2021.

Chemours says its Opteon XL HFO refrigerants are the lowest GWP and long-term options under F-Gas Regulation for transport refrigeration, reducing CO2 emissions by up to 85% when compared to R452A and 94% compared to R404A. Diego Boeri said: “Transport refrigeration is critical to the viability of the global cold chain and we are excited to work in collaboration with Carrier Transicold to provide Opteon XL products as a more sustainable solution that meets the stringent performance needs of this application.’’

Cascade control for Aquarea heat pumps Panasonic has introduced a new Aquarea Cascade Controller designed to deliver increased energy efficiency for large applications.

The controller can operate up to 10 Aquarea air to water heat pumps (160kW) simultaneously or in cascade mode, which it says helps to meet the heating or cooling demand of commercial buildings more efficiently.

Cascade control is increasingly being utilised for large projects, making use of parallel-connected heat pumps and switching on the most efficient number of these as demand is increased or decreased.

The new controller directly integrates with the building’s BEMS by a built-in modbus for a smart way to manage heating, cooling, domestic hot water (DHW) and monitor energyusage. Photovoltaic solar panel functions, a 3-way external valve for cooling and up to three external heat meters can also be connected to the controller at one time, enabling facilities managers and maintenance professionals to oversee all operations and view essential information in one place.

In addition, the controller includes a touch screen display with information about each of the connected heat pumps - ideal for quick servicing and maintenance tasks. www.aircon.panasonic.eu

The variety of sensor types within the product line offer significant user benefits, including flexibility with refrigerant leak detection and providing peace of mind when helping to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378 inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk-in freezers.

Other features include a mobile app interface for commissioning and maintenance without special tools and an added sensor life of 5–7 years with plug and play pre-calibrated sensor modules.

CONDAIR EXPANDS DEHUMIDFIER RANGE

Condair has extended its dehumidifier range to include more desiccant models, wall and ceiling-mounted systems, units that control temperature as well as humidity, and swimming pool units.

Head of sales Tim Scott said: “Having successfully launched Condair dehumidifiers to the UK market just a few years ago, it is very exciting to be able to further strengthen our portfolio of dehumidification systems. Condair now boasts one of the most extensive ranges of dehumidifiers available from a single supplier, as well as offering fully customised solutions for unusual projects or extreme control. Whatever application, capacity or humidity level is needed, Condair has the dehumidifier to perfectly meet the requirement.”

ZAbluefin leads way on efficiency Ziehl-Abegg is the first company worldwide to certify a product range for the new fan energy index (FEI).

The energy efficiency metric was introduced last year by Air Movement and Control Association (AMCA) International to save energy, reduce operating costs, and accelerate decarbonisation.

A total of 27 ZAbluefin centrifugal fans with GR modules in several combinations using different motors are certified, as are the former product range Cpro and C. Ziehl-Abegg has operated the world’s largest combined measurement and test chamber for fans in Künzelsau since 2008 and believes that high-precision measuring instruments and regular training for employees, combined with routine inspections by external organizations such as AMCA, are essential to continuing to inspire customers confidence in its products.

MEAT AGEING FROM WILLIAMS

Williams has launched a meat ageing refrigerator alongside its established range of walk-in products.

The process of ageing meat has been around for centuries but its emergence into more mainstream dining culture is a result of the foodservice industry becoming more aware of how the process improves the flavour and texture of meat.

Key to the process are the conditions in which the meat is stored, with not just temperature but also humidity vital to the final flavour.

The new refrigerator operates at the ideal temperature range of +1 to +6°C and provides humidity between 60-90%, ensuring that meat ages perfectly. The inclusion of Himalayan salt blocks assists with moisture management and improves the flavour of the meat.

It is able to operate in environments of up to 43°C and the interior is lit with energy saving LEDs, making it perfect for front of house display. The correct ageing conditions are maintained by the presence of a self-closing glass door, coupled with heavy duty, PVC magnetic balloon gaskets that provide a 100% tight seal. A barrel lock also provides security and reassurance in a front of house setting.

TOSHIBA UPDATES DESIGN SOFTWARE

TROX PWX for prestige project

TROX will supply PWX fancoils for the second building at Paradise, Birmingham - Two Chamberlain Square.

BAM Construction chose TROX for the project, which will see the 183,000 sq ft office building, designed by Glenn Howells Architects, join the first building in offering a total 350,000+ sq ft of Grade 1 office space as part of the Paradise masterplan, inspired by the Victorian architecture of the city’s Grade 1 listed Town Hall and Council House.

Launched in 2017, the PWX fancoil was the result of an extensive research and development programme involving a comprehensive rethink of fancoil technology. As a result, specifiers are able to input exact performance criteria for a wide range of thermal and acoustic scenarios, instead of having to rely on ‘anticipated’ or ‘expected’ data.

The PWX units feature new inlet attenuators, inlet plenums and discharge attenuators which TROX says are capable of achieving outstanding performance across a wide range of applications.

Toshiba has released a new generation of its air conditioning system design software, which now enables contractors to carry out both split and VRF system selections and automated EN378 F-Gas compliance checks.

DesignAIRS was originally developed by Toshiba in Europe, and the company recently adopted the system as its global air conditioning design platform. While the first generation covered only VRF systems, the latest version enables a range of technologies to be added to designs, including split systems, heat recovery, hot water modules and DX-based air handling units, expanding its application.

In addition to automatically evaluating compliance with mandatory refrigerant safety standards, the new programme simulates true system capacity for designs. This assures clients and end users that a proposed solution will meet both statutory and project performance requirements.

In addition to creating detailed project drawings for a variety of building types, including pipework and equipment specifications, the new version includes a seasonal performance calculator that allows designers to simulate the actual performance and running costs of a system using local seasonal temperatures and operating conditions.

Comfort cooling strikes right note at Flint Hotel

How VRF technology and wall mounted units from LG helped to transform a historic property.

The hotel owner is delighted with the indoor units

LG Multi V 5 VRF and Artcool Mirror units have been chosen for a new Belfast hotel.

Period features have been brought together in a modern format at the Flint Hotel, with the Artcool wall mounted units installed in bedrooms and landing areas.

Ben Ringland, director of the Ringland Group and owner of the Flint Hotel, said: “Our focus has been to design our hotels by moving away from a traditional corporate feel to attract a younger demographic. We needed appliances which fit that mould and the mirror units available from LG ticked every box. They look fantastic and you’d never know they are there.”

Designed and supplied by Exi-tite and installed by Duct Services Northern Ireland, LG Multi V 5 monitors humidity as well as temperature and the dual-sensing control systems optimise seasonal efficiencies up to 9.46 EER when using smart load control, a self-regulating variable load feature.

These common heat pump and heat recovery modules make up eight individual VRF systems across the hotel, connected to 74 indoor fan coils and reaching a total capacity of 280kW. Connected to all eight systems is the AC Smart touch screen central controller in the reception area. This 10.2-inch TFT LCD unit provides the hotel management with full control and monitoring over the

the air passing through them. As the room approaches the user’s setpoint, the system produces an air temperature close to that of the room. This reduces any draught felt by the user dramatically and improves their thermal comfort.”

To ensure the air conditioning units are easy to use, ‘Simple’ wall mounted controllers have been installed in each room. With on/ off, temperature adjustment, fan speed and mode selection, customers have simple but effective control over their environment.

Noel Conway, owner of Duct Services Northern Ireland, said: “With the nature of this building installation into the old fabric wasn’t without complications but using the LG equipment made light of most of this.

The pipe lengths that we could achieve working through existing voids, and the relatively small size of the heat recovery boxes made the fit out enjoyable to work on. I’ve been really impressed with how the systems set up, the commissioning from a mobile phone application and the overall quietness of the units inside and out.” www.exi-tite.com

Andrew Robinson, managing director of Exitite, said: “The Multi V 5 is an ideal piece of equipment for the hospitality sector.

Using a feature called comfort cooling, the indoor units reduce their cooling impact to LG Multi V 5 VRF units on the roof at the Flint Hotel in Belfast city centre

Feel proud, you’re helping to save the planet Ben Bartle-Ross says the industry is playing an important role as the world looks towards a more sustainable future.

Most of the air conditioning and heat pump engineers I see on our regular training courses are all aware that the equipment they install consumes energy.

They also know that this equipment is delivering modern levels of comfort to people and that it can do so in some of the most energy efficient ways known to man.

So I always try to instil a bit of pride in what they are doing because I do believe that together, we are making a difference in lowering humanity’s carbon footprint.

now accepts that we can’t just continue ‘burning’ things’ to keep us warm.

We also can’t all go back to living in caves though and as we see our electricity grid get greener and greener, with more primary production from renewable and sustainable sources, then the arguments for electric heating and cooling grow even stronger.

Modern heat pumps and air conditioning systems will deliver effective, low carbon buildings but it needs to be done in the most energy efficient ways possible.

Abandon modern life

Education is key

Now I know there are others who think we should just abandon modern life and go back to a much more basic way of living.

Who knows, they may be right.

At the same time though, we exist in the 21st Century and few want to give up on feeling comfortable inside whatever building they occupy.

In fact, studies now show that comfort levels within buildings can have a massive and positive effect on the wellbeing of the occupants and on productivity levels.

Almost everyone though accepts that we need to deliver this comfort in a much, much more sustainable way.

That is why we as a manufacturer invest so heavily in our training facilities.

We know we build some of the best equipment in the world, but if it is not designed, installed, commissioned and maintained properly, then it could be wasting needless energy and increasing the carbon footprint of the building.

One key element of this is how the system is controlled and THE KEY element to ensure that building owners, facilities teams and homeowners get the best out of any equipment is education.

A different way of doing things And this is my point about being proud of what we in the HVAC industry do.

We are right at the end of the gas and oil phase of society and almost everyone

That is also why we invest heavily in short videos on our YouTube channel, so that engineers can refresh the training they have had, whilst out on site and end users can learn these things for themselves.

We need to believe Anyone who knows me will know how passionate I am about training and I try to bring this enthusiasm into the classroom so that people attending our courses understand how important their role in the industry can be.

As an industry, we often sit hidden from the rest of society. In fact, I’ve started saying to people that they are being trained on equipment that most people simply do not care about. They just expect it to work.

If they are at home, they expect their heating to work.

If they are in an office, shopping or at leisure, they just expect comfort.

That is where modern life has led us to.

And we can help deliver this … and we can do so in ways that minimise the amount of energy needed.

So feel proud. You are part of a sustainable movement that doesn’t need to put up tents in Oxford Circus.

You are just quietly getting on with it!

Fujitsu aims to widen reach t h Manufacturer believes new additions and strong VRF range provide the platform for further growth.

Fujitsu believes VRF will remain a key part of future growth as it extends its UK product range into the chiller sector.

Clint and Montair liquid units are already in the country and Fujitsu-branded mini chillers and inverter chillers are expected to be available from the autumn.

The move is a result of a partnership established in 2017 between Fujitsu General and G.I Holding (GIH), and the coming joint development units will feature Fujitsu’s inverter technology.

Ian Carroll, Fujitsu chief operating officer, said: “This is an important joint product development for both companies, and we are excited about the new products coming through.

"We will combine the extensive technological resource available throughout the organisation and its partners with the high-quality level of support provided by the teams in the UK. The Clint and Montair combinations with new low GWP refrigerant options will provide the opportunity to meet specifications across a wide market.”

The initial offering covers both air-cooled and water-cooled liquid chillers, in heat pump and cooling only models.

The air-cooled heat pumps will range from a compact 15 kW capacity model for small commercial applications using inverter scroll technology, through to 1.6 MW screw compressor models for large commercial and industrial projects, including options of producing hot water up to 60°C. Water-cooled heat pumps range from 49 kW to 1.25 MW, with cooling only variants using Turbocor centrifugal technology to extend ranges to 3.9 MW capacity.

Close control applications are being provided with Montair air-cooled, watercooled and chilled water variations, covering a range of 9 kW to 155 kW capacity. Fujitsu has already won a £1.3million contract in the close control market.

Open protocol communication is included across the range, with remote web monitoring packages supplied as standard on Turbocor models. Dry coolers, hydronic modules and remote condensers complete the line-up.

The J-Series mini VRF was launched 15 years ago

Sales growth Fujitsu says its overall UK sales have nearly doubled over the last five years and, speaking at an open day at the company’s Elstree HQ, Carroll was also keen to emphasise the importance of the manufacturer’s VRF range. He said: “Our VRF is as good as anyone’s but we have to convince some customers of that. It is 15 years since the launch of the J-Series, the original mini VRF. It started at 14kW and the family has now grown to 50kW.’’ Alongside technical manager Martyn Ives, Carroll also underlined the company’s ongoing commitment to customer service.

He said: “Everything we do is about customer service and that builds the brand.

We have always had a good reputation for equipment and now, per capita, we probably have more technical people than any other manufacturer.’’

The investment in technical expertise is reflected in the expansion of Fujitsu’s training network, which now includes Belfast, Glasgow, Leeds, Dudley and Eastleigh in addition to Elstree. Training numbers have increased by 300% compared to the previous year.

Two new partner schemes which are directly linked to warranties have also been launched. Focusing on education, there is no minimum value of sales to achieve membership of the Infinity Partner and Elite Infinity Partner schemes. On completion of a number of technical training courses each year, partners will receive extended product warranties along with extra incentives including marketing support.

Martyn Ives said: “We have seen that customers who undertake a comprehensive product training programme are less likely to raise a warranty claim than those who have not been trained. Education is a main focus of Fujitsu and is a key reason why we have taken this step to link the two together in our new approach.”

More than 100 people attended the Fujitsu open day, including customers, suppliers and distribution partners

Fujitsu forecasts that 85% of its residential and packaged systems under 14kW will be available with R32 refrigerant before the end of the year. The company says that these products will run alongside each other whilst Fujitsu gradually phase out R410a

VRF case study: Heat recovery system provides solution for medical imaging engineers.

A Fujitsu Airstage VRII heat recovery system has been chosen by a company that services and repairs medical diagnostic imaging equipment.

Health Imaging Solutions wanted a comfortable and stable environment for its employees in Dinnington, South Yorkshire, and selected a system which provides individual climate control for offices, meeting rooms and common areas.

The space-saving 28kW VRF outdoor module has a footprint of just 0.71m2 and is located in a purpose-built compound adjacent to the building. With three individual refrigerant branch boxes inside, each connected to a four-way cassette, the module’s electrical panel can be repositioned for better access.

Mark Derriman, Fujitsu’s southern business development manager, said: “Having an existing ceiling grid of 600 x 600mm, the compact cassette’s chassis fits perfectly without having to adjust the grid and kept the work required for installation to a minimum. Our new circular flow cassette provides 360-degree air flow and worked out an ideal choice for the large meeting room, as the air that is distributed reaches every corner.

The outdoor unit compound at Health Imaging Solutions

Reliability “The installation in these offices and meeting rooms is all about thermal comfort, hence the reason for a heat recovery VRF. The system can provide simultaneous cooling and heating and works by reusing heat energy rather than wasting it. The system is capable of reaching operating efficiencies of up to 8.82, over 800%. We commissioned the system by reducing the cassettes’ pre-set external static pressure selections within the controllers. With a low ceiling, the people sitting under our units don’t suffer from any draughts and so are always comfortable when working.”

The installation was carried out by Orpington-based Friargreen Construction, who specialise in turnkey projects for clients in the healthcare sector. Managing director Toby Sparks said: “The project

had to be one of quality, not only the installation but also the equipment. The wall mounted systems that are installed are located in rooms with servers that are operating when staff are servicing or testing CT scanning equipment. Failure to regulate the temperature of these servers could result in huge losses to the business in down-time. We chose to use Fujitsu because we have been extremely impressed with the high level of support they have provided in the past and because the equipment is known for its reliability. I have absolutely no hesitation in recommending them for projects like these. They are a great partner to have in our supply chain.”

Meeting the demands of Lot 21 Martin Passingham, DX product manager for Daikin UK, explores the importance of Lot 21 in the industry and how VRV IV+ is leading the way towards meeting the new European Directive for Energy related Products (ErP) requirements by improving the seasonal efficiency.

Seasonal efficiency measures the true energy efficiency of heating and cooling systems during a period of one year. Unlike older heating and cooling methodologies, seasonal efficiency tracks a system’s daily operations to include temperature fluctuations and standby periods. After one year, the seasonal efficiency data gives a more in-depth, reliable and true overview of a system’s actual energy consumption.

This is important because more than 95% of the environmental impact of HVAC systems comes from indirect emissions, which is the measured energy consumption of the unit.

The European Directive on Ecodesign Requirements for ErP 2009/125/EC covers the indirect emissions (i.e. energy consumption) of a whole host of products.

In relation to the systems that Daikin manufactures, Lot 21 of the ErP Directive is the category that considers air heating products, cooling products, high temperature process chillers and fan coil units for systems greater than 12kW when operating in cooling.

June | July 2019

Daikin VRV.indd 22

Lot 21 uses a new measure of seasonal efficiency (referred to as Eta or ŋs, h and ŋs, c) which is the SCOP or SEER seasonal efficiency divided by the primary energy conversion factor (fixed as 2.5) minus the negative effect of controls on efficiency, which is 3%.

In heating: ŋs,h% = (SCOP/CC)-ŋF(i) In cooling: ŋs,c% = (SEER/CC)- ŋF(i) SCOP: Seasonal co-efficient of performance SEER; Seasonal Energy Efficiency ratio CC: Primary energy conversion factor ∑Fi Sum of negative effect of controls on efficiency From January, the minimum energy efficiency of air to air heat pumps is 133% ŋs,h% in heating and 181% ŋs,c% in cooling.

These minimum requirements will increase again on 1 January 2021 to a minimum of 137% ŋs,h% in heating and 189% ŋs,c% in cooling.

Luckily, Daikin has already taken great steps to ensure that VRV IV+ offers increased seasonal efficiency ratings, not just complying with the new Lot 21 legislation of the ErP regulations but exceeding them, thanks to brand new and improved

compressor technology that delivers vastly improved seasonal efficiency in real world conditions, and which represents the next step in innovation within the VRV IV range since its launch in 2014.

Five years ago, Daikin’s pioneering revolutionary VRV IV system set a new standard in the industry, pioneering new levels of seasonal efficiency and comfort, which have since been introduced throughout the VRV IV heat pump, heat recovery, and water-cooled models. The launch of VRV IV+ heat pump once again sets a new benchmark for seasonal efficiency.

At the heart of the latest system, existing VRV IV features such as Variable Refrigerant Temperature (VRT) and continuous heating during defrost are matched by a completely redesigned compressor, which is fully optimised to ensure high performance at part loads - the main operation mode throughout the year.

As a result VRV IV+ is already compliant with the new ENER LOT21 Tier 2 due to come into force in 2021.

Volume 5 No.4

30/05/2019 12:54

AIR CO NDITIO NIN G New standard Furthermore, the new compressor addresses a key issue that can occur during low load operation, which is that refrigerant leaks can occur from the high-pressure side to the lowpressure side in the compression chamber, resulting in loss of efficiency (Fig 1, below). In the new compressor, this has been resolved with the inclusion of a backpressure control port that sends a small amount of high-pressure refrigerant from the compression chamber to the back of the scroll (Fig 2). This optimal separation of lower and higher-pressure sides within the compression chamber boosts seasonal efficiency to a new standard, delivering a 15% increase in efficiency.

VRV IV+ also uses a 4-sided heat exchanger with a new capillary design for optimised refrigerant distribution, providing the smoothest performance in any system loading.

As a result of all these innovations, VRV IV+ delivers 15% higher average seasonal energy efficiency ratio (SEER).

With indoor ducts the system SEER is as high as 38% higher with an 8HP unit and 41% higher SEER with indoor cassettes.

In heating mode, VRV IV+ delivers 13% higher Seasonal coefficient of performance (SCOP) on average, or 16% higher SCOP for an 8 HP unit with indoor ducts. These developments in efficiency are what make the VRV IV+ a stand out system, through rigorous testing in true to life conditions, Daikin is proud to bring this developed technology to the market, exceeding the efficiency requirements of Lot 21 So that designers can directly compare the efficiency of different systems, the ENER LOT21 free access website Fig 1

publishes data on different systemsâ&#x20AC;&#x2122; energy efficiency. This data is used to inform the technologies included on the ECAâ&#x20AC;&#x2122;s Energy Technology Product List, Building Regulations and wider technology benchmarking. It is important for contractors and consultants to be able to benchmark the performance of both like for like systems and when comparing the efficiency of different types of technologies. So it is equally important that the data represents real life performance in a real system design within a building, rather than being modelled on a unit selection that will never be used in an actual application, in order to make the system appear as efficient as possible.

Not only have the tests been carried out in true to life conditions over the period of a year, to get the real picture of the capacity of the VRV IV+ but also, using the correct sized units for the conditions tested in, again to attain the most accurate and true ratings, to ensure absolute clarity for consultants and ultimately the end-user.

It is important to us, as an organisation with a high regard for our environmental responsibilities, to know that the information we produce and promote to our customers is reliable and true.

It has to be noted that, despite the need to comply with the Lot 21 legislation for HVAC products, there is no set requirement for the way tests are carried out and therefore some manufacturers may choose to provide unrealistic system selections in order to make their technology seem more efficient than it is in real life applications. However, Daikin is fundamentally opposed to this approach and instead chooses to conform to the spirit of the legislation and be transparent in every way.

With its next generation compressor technology that improves seasonal efficiency, the VRV IV+ is taking the next step in the journey towards lower GWP technologies and reduced carbon emissions. As the global leader in HVAC systems, Daikin is committed to upholding the principles of the Ecodesign Requirements for ErP by providing accurate energy efficiency ratings for its products that specifiers and end-users can trust will offer a genuine reflection of their performance in real life.

Progressive partnership

Andrew Faulkner, commercial manager at Samsung Climate, explores the strategy to redesign all split system models to operate on R32 refrigerant, and the decision to partner with air conditioning and refrigeration distributor TF Solutions as its sole National Wholesale Distributor in the UK. At the start of 2019, Samsung Electronics Air Conditioner Europe (SEACE) announced a progressive switch to new and lower GWP refrigerant R32 across its entire residential and light commercial air conditioning split system ranges.

Having already launched RAC split systems with R32 in 2018, we observed a significant take-up of the new refrigerant and decided to extend the R32 rollout to the commercial split system range.

However, rather than a phased launch, we decided to redesign all the split system models up to 14kW to operate on the new refrigerant, offering a full choice of models to Samsung customers. But most importantly, we made the decision not to immediately cease availability of the R410A models.

It was recognised that some customers were not yet ready to wholly switch across to R32 and so, this year, we at Samsung will give customers the choice of systems using R410A or R32 refrigerants, to give them time to attend training courses and adjust. However, based on current sales data, the business is expecting the majority of its split system sales to switch to R32 by early 2020.

Whilst the introduction of a direct sales channel in 2017 addressed the balance, our overall strategy was to bring on board a suitable wholesaler or stocking partner within the UK. RAC/CAC split systems especially rely on availability as well as price and specific product features and benefits. One of the benefits of the partnership for us is TFâ&#x20AC;&#x2122;s new Bristol branch and its other four locations giving great coverage for Samsungâ&#x20AC;&#x2122;s innovative

products such as Wind Free, 360 and Mini Eco HR. Leveraging their branch footprint, TF Solutions are able to provide immediately accessible stock all around the country, thanks to their large 10,000+ sq ft warehouses, and we are proud to say they are our only stocking wholesale partner.

Both the teams here at Samsung and TF Solutions wish to grow our respective businesses and the blend of Samsung innovation and technology together with TFâ&#x20AC;&#x2122;s award-winning wholesaling business ensures a strong partnership and joint proposition to the market. www.samsung.com/uk/climate

Joint proposition In March, we announced the new appointment of TF Solutions as our only National Wholesale Distributor in the UK. Before the partnership was announced, Samsung Climate Solutions UK distribution business was predominantly DVM/VRF.

Debunking the F-Gas myths Event organised to get industry talking helps to bring clarity for contractors and resellers.

Almost 100 people attended two seminars in Birmingham hosted by Logicool and REFCOM designed to cut through the confusion surrounding the F-Gas legislation.

One session was for contractors and the other for resellers, which included manufacturers, wholesalers and distributors.

The presentations focused on a number of misconceptions regarding the wording and interpretation of the legislation.

Karl Richardson of Logicool began by highlighting a number of statements with the potential to cause confusion and asked Graeme Fox of REFCOM to interpret the legislation correctly.

The presentation and conversation then developed to focus on a number of key questions, dubbed “F-Gas Myths and Realities.” These primarily focused on certification, as well as the sale and resale of refrigerant and equipment to trade and non-trade.

1. Myth or Reality? I’ve got my F-Gas so I don’t need any further training to work with A2Ls or flammable gases.

Myth: F-Gas qualification is not Company F-Gas. The Company F-Gas certificate is required in all instances for purchasing.

An F-Gas qualification is not a recognition

June | July 2019

F-Gas Myths.indd 26

of competence. The Company F-Gas is the legislative requirement.

2. Myth or Reality? An HVAC “installer” company does not need to directly employ F-Gas qualified engineers – their subcontractors being F-Gas qualified is enough for them to obtain company registration and certification.

Myth: When applying for Company F-Gas the applying company or individual needs to provide evidence that they employ (not sub-contract) qualified personnel and also “have the necessary tools and procedures… available to the natural persons engaged in activities for which certification is required”.

Essentially this means that a company applying for Company F-Gas MUST directly employ qualified engineers and cannot use sub-contractors as nominated engineers.

"The most emotive subject of the day was online sales.

At the time of writing it is possible for anyone to buy a DX system without being asked for F-Gas certification''

3. Myth or Reality? I’m doing an install for my mate/parents/family friend/etc. I am F-Gas qualified, so I am not breaching any regulations. If not, I’m covered by my employer’s REFCOM registration.

Myth: Please see response to Question 1.

All sales are to entities with Company F-Gas only.

4. Myth or Reality? I’ve got some spare refrigerant I don’t need – I can sell it to anyone who is F-Gas qualified.

Myth: Please see response to Question 1.

All sales are to entities with Company F-Gas only. You must have a Company F-Gas registration if you want to either install, maintain, service, repair, decommission systems or purchase refrigerant.

5. Myth or Reality? A reseller can legally sell a system online without mention of F-Gas, providing that the purchaser supplies proof at a later date that the system was installed by a qualified engineer or company.

Myth: Evidence of who will be installing the system must be provided BEFORE the supply of the system. Resellers should not supply systems until evidence of Company F-Gas is provided prior to the sale and supply of the system.

This subject raised a number of

Volume 5 No.4

30/05/2019 12:57

REG ULATIO N concerned responses and it was agreed that a large percentage of online resellers are in contravention of the regulation.

Many of the attendees from the engineers seminar demanded a stop to this and questioned who is policing the regulation and why this activity is allowed to continue. Mr Fox explained that Refcom is a certification body only but that complaints could be made to the Environment Agency, which is are duty bound to follow up on complaints and to copy in REFCOM, which is monitoring compliance.

6. Myth or Reality? I don’t need to have an F-Gas certificate because I do car AC and it is the MAC Directive not F-Gas that covers this sector.

Myth: Having a MAC certificate does not therefore allow you to be competent on the application of other refrigerants such as R410a and R32. All purchasers of refrigerant require a Company F-Gas certificate. The MAC enables purchase only for the use of refrigerants in car air conditioning systems.

7. Myth or Reality? A reseller can sell to anyone who holds an F-Gas qualification.

Myth: Company F-Gas only. Someone purchasing equipment to resell on has to abide by the same rules as the main wholesaler/distributor. That reseller does not need to hold a REFCOM registration, as the last sentence in paragraph 4 of Article 11 says, but the seller must beware of those seeking to circumvent the rules.

8. Myth or Reality? I’m a wholesaler so I don’t need to be registered myself.

Agreed that this is potentially debateable but how many wholesalers/distributors or resellers do not get involved with technical support on-site? Mr. Fox asked the audience: “Do your technical support staff go to site to assist your customers with commissioning, fault diagnostics etc? Do they ever physically touch the gauges or hoses?

Therefore, resellers should be registered under the Company scheme.’’

27

Key outcomes from the day When reading the F-Gas legislation it needs to be understood that “Company” does not mean a trading company. A Company F-Gas is not only required for a trading entity. Anyone, including qualified individuals installing a system containing F-Gases or purchasing F-Gases, requires Company F-Gas Certification. One key piece of information cleared up on the day is that in this instance the word “Company” is legislative language.

An F-Gas qualified engineer installing a system for a friend at the weekend requires their own Company F-Gas certificate. Failure to produce evidence of this when purchasing a system and failure of the reseller to check for this engineers Company F-Gas Certificate both contravene the regulations.

The seller of the equipment has a requirement to check for the Company F-Gas Certificate in advance of the supply of the equipment. No Company F-Gas Certificate equals no supply of equipment. Any reseller operating outside of this is in breach of the regulations.

The most emotive subject of the day was online sales. At the time of writing, it is possible for anyone to purchase a DX air conditioning system in the space of five minutes without being asked for evidence of F-Gas certification. These systems can be sourced from a number of online outlets in the UK and a number of these are operated by installing contractors who hold a Company F-Gas Certificate but then are in potential breach of the regulations with regards to online sales.

Successes Several contractors said that they had learned from the day and that the efforts of Logicool and REFCOM had helped explain some of the confusing text within the regulation. Feedback from the suppliers conference was even more positive. One major national wholesaler and one major manufacturer said that they were going to review their own procedures with immediate effect. Another major supplier commented “to say it was informative was something of an understatement”.

Karl Richardson asked Graeme Fox whether a version of REFCOM Elite could be set up for suppliers so that some companies could opt to join an agreed code of conduct that would work above and beyond both the existing legislation, and could be termed as the “spirit of the regulation”. Since then a number of resellers have asked if this has potential and REFCOM is now exploring the possibilities of this idea.

Also in attendance was Paul Singh from the Birmingham Society of Refrigeration and Air Conditioning (BSRA) who assisted with the Q&A. Logicool used the opportunity of funding the event to help increase awareness of the local society.

NEW AMD DECKING FIXING FROM LINDAPTER

ADVANCED MAKES CLEANING EASIER

Lindapter has extended its product range with the AMD Decking Fixing, developed to allow building services to be suspended from decking profiles manufactured by Anglian Metal Deck.

Advanced Enginering says maintaining AC units is easier with the two latest aditions to its cleaning range.

The new CE-marked fixing is installed within seconds and is adjustable onsite without specialist labour, expensive tools or power.

The fixing is suitable for the installation of HVAC systems, fire protection, pipework, electrical equipment and lowered ceilings. It fits inside the reentrant channel of the decking profile and held in place by a locking plate and locknut. This zero-impact fixing preserves the strength of the decking profile and avoids delamination or damage to the deck.

As with all Lindapter products, safe working loads are independently approved and rigorous quality procedures ensure a secure connection with a capacity of 1.00kN per fixing, calculated at a safety factor of 3:1.

° Quick and easy to install - saving time on site. °A djustable onsite - providing flexibility during installation. ° S pecialist labour not required - controlling costs. ° Z ero-impact installation - avoids delamination and damage to the deck.

The HydroSprayer-Elite was recently launched as an electric alternative to the HydroSprayer. Designed for use with Advanced concentrated and ready-mixed coil cleaner chemicals, the HydroSprayerElite can be used indoors or out.

The 12-volt electric sprayer features a fully-rechargeable battery, 15 litres of capacity, and supportive backstraps.

Following a brief departure from the market, Advanced has now secured a new supplier for its HookTite protective covers. Ideal for routine maintenance, HookTite helps protect walls, carpets and nearby equipment against accidental splashes during cleaning.

Colin Pratt, technical director of Advanced Engineering, said: “HookTite has been specifically designed for use on cassette units and features access holes to prevent spills, and a drain tube that directs any run-off for easy collection and disposal. But best of all, it saves customers time and money.”

Following on from last year’s successful launch of the R32 Sinclair Vision wall mounted split system, Thermofrost Cryo is adding Spectrum and Cassette models to its 2019 offering.

The manufacturer says the controller has been developed in response to increasing demand from users for more flexibility and offers a fresh approach to heat pump commissioning and control.

In Spring 2018, the Madoka was one of five Daikin products to receive recognition for innovative design and aesthetic at the iF Design Awards and the Red Dot Design Awards 2018.

Daikin says end-users are able to increase their energy savings, thanks to the smart modulating room control. This function ensures a more stable room temperature, by lowering or raising the water temperatures depending on room temperature requirements, as well as reducing on/ off cycling times.

In residential applications, Daikin says the Madoka controller makes status checks simple and enables homeowners to set space heating/ cooling and domestic hot water operation to suit their own preferences.

The Spectrum is a stylish high wall system, which like the Vision range features embedded Wifi as standard. The range will appeal to those looking for a more contemporary feel and is available in four models with 2.7, 3.5, 5.3 and 7.0 kW capacities. Prices are highly competitive, starting at £399 net trade.

The Cassette system widens the appeal of the Sinclair range and provides access to the commercial market. With capacities at 3.5, 5.0, 7.0, 8.5 and 10.0 kW, the whole range is available for single phase power.

Prices are again highly competitive, staring at £699 net trade.

Started as a summer only, price-point, special offer product, the Sinclair range has grown in popularity to become available year-round in the Thermofrost Cryo product portfolio.

Royal seal of approval

Proud winners of the Queen’s Award for Enterprise for a third time, this time for International Trade, Aspen Pumps CEO Adrian Thompson gives ACR Journal his thoughts on the company’s continued growth as an international house of brands.

What have been the driving factors in Aspen’s successes so far?

This philosophy is demonstrated with the launch of the new Silent + Mini Lime pump.

The trend towards quieter AC equipment and increasing numbers of domestic installations means near silent pumps are needed. However, pump noise is not the only issue; pump vibration is often a major contributing factor. Our new generation of mini pumps will all have our patented anti-vibration technology which makes a significant reduction on the installed noise levels.

But it is not just about innovation.

Engineers like to talk to engineers and

A strong foundation - Aspen Pumps was established by three ACR engineers in 1992 who had great insight into the daily life of a contractor.

The key motivation for setting up Aspen Pumps was frustration; unable to find a reliable and easy to install condensate pump, they decided to make their own. The solution was the world’s first peristaltic condensate pump.

This was quickly followed by their next stroke of genius, the innovative use of colours as a key aspect in product design something which has been maintained to this day. This helped to differentiate the pumps and also created its own energy around the Aspen brand.

From these humble beginnings, Aspen Pumps has become a truly multinational business with a global distribution network spanning over 100 countries. Today, over 70% of our revenue comes from export sales.

We have kept to the founders’ values and maintained a relentless focus on innovation and continuous product development. ACR engineering is at the very centre of our business. This simple business approach has been fundamental in achieving our international position.

therefore if you phone Aspen for advice you can talk to an ACR engineer who understands the issues at first hand.

How do you see Aspen growing over the next 5 years?

What impact do you feel the previous Queen’s Awards have had on the business?

By its nature, the Queen’s Award can only be won by British companies. As a British manufacturer, these unique accolades have allowed us to build our reputation in overseas markets. We are proud to promote British engineering and manufacturing on the global stage.

In the last few years alone, we have successfully expanded our international footprint with operations in Australia, India, France, Germany and the USA. Being recognised with such prestigious awards has helped Aspen to stand out, giving our customers faith in the quality of our products and our entire business operation.

June | July 2019

Aspen.indd 32

What do you think sets Aspen apart from its competitors?

From its modest beginnings, Aspen has always strived to make life easier for the ACR engineer. As a company, we listen to the needs of the engineer and are in continuous pursuit of innovations to help them get the job done.

ACR is a fast paced market and you can never stand still; innovation and international sales expansion remain our main priorities.

New products are at Aspen’s core and we have a strong pipeline of product launches, which is not only focused on pumps. Over the last two years we have added JAVAC and Advanced Engineering into the Aspen Pumps family. Both of these companies are well established UK market leaders with strong reputations built on product quality and innovation. We are looking forward to developing these brands on the international stage. Expect some exciting new products soon!

Receiving another Queen’s Award will help us develop our international presence.

The USA and India are key growth markets and both have a have a fondness for the UK and its royal heritage. This award will help open doors and give the business a higher profile. We are also looking to expanding our international presence in emerging markets with the Asia Pacific region now becoming a major focus for the business.

We are very much looking forward to what the future holds for Aspen Pumps Group and will continue to support our global distribution partners who have a major part in Aspen Pumps' success.

How to prevent pipework corrosion Insulating pipework and support brackets with the same material improves energy efficiency and protects against bi-metallic corrosion in both cold and hot pipework. Anthony Barnett, technical marketing manager at Armacell, looks at the factors to consider.

The durability of materials obviously has a bearing on the longevity of all building elements. Factors such as condensation and vibration/ structural stress all take their toll on HVAC systems. While it’s the designer’s responsibility to ensure that exposed elements of a building are fit for purpose, it is important that suppliers provide their input, especially in the often overlooked area of bi-metallic material corrosion.

Bi-metallic or galvanic corrosion occurs as a result of the flow of very small electric currents in the presence of moisture and oxygen between two dissimilar metals. This causes the more anodic of the two metals to corrode, whilst the other metal (called the ‘noble’ metal) remains unaffected.

For example, brass or copper pipework (ranked higher on the Galvanic series) with steel fittings and hanger brackets (ranked lower) will result in the steel undergoing accelerated corrosion.

It’s worth bearing in mind that the two metals don’t need to be in contact for galvanic corrosion to occur. When a more ‘noble’ metal corrodes slightly and dissolves in moisture from condensation and subsequently drips over a less noble metal it will result in corrosion of the latter.

Galvanic corrosion is therefore an issue that needs to be taken into account at design stage when specifying both pipework, fittings and support brackets.

June | July 2019

Armacell.indd 34

However, using two or more different metals within an HVAC system does not necessarily mean corrosion will occur if you follow a few basic rules. In most cases insulating the pipe, fittings and hangers with an appropriate material will separate the two metals, eliminate condensation and avoid any galvanic corrosion.

Insulating copper-zinc alloys (brass) pipework Specifying an inappropriate insulation can actually aggravate the problem of corrosion on pipework by concentrating sodium chloride particles against the pipe surface, causing stress corrosion cracking (SCC), even on stainless steel. Predominantly, this is caused by the chloride particles always being present in the general construction and building environment, such as on the hands of the installer in the form of sweat.

The corrosion is triggered by the chloride ions in combination with moisture and operating temperatures above 35°C. As such, the percentage by mass share

of water-soluble chloride ions in the insulation material for stainless steel pipes should not exceed 0.05%. Armaflex is especially suitable for use on stainless steel, as it is produced completely without halogens (chlorides). Even then, it is important to avoid contamination of the steel with chlorides from hands or surrounding air.

Copper-zinc alloys (brass) pipework is vulnerable to crystalline stress corrosion cracking at temperatures above 50°C. Ammonia or nitrides (ammonia and nitrogen combinations), in the presence of moisture, cause this type of corrosion.

To combat this, we recommend insulation materials such as Armaflex, which has a mass share of ammonia that does not exceed 0.2%.

We also recommend a foil vapour barrier underneath the insulation after a thorough cleaning of pipe surfaces, to avoid issues with both halogen and nitrides.

Support brackets Pipe support brackets can be a potential trouble spot due to a number of factors.

Firstly, they can be susceptible to galvanic corrosion (e.g. steel to copper contact).

In addition, direct fixing of cold services pipework to their mounting brackets acts as a thermal bridge from surrounding warmer ambient air. Since these un-insulated supports on chilled water and refrigeration pipework fall below the dew point, moisture is continually drawn to the cold brackets

secondary damage to surrounding goods and equipment can be prevented.

The PET segments can be completely recycled at the end of their service life, with all production scrap flowing back into new PET blocks. PET has an excellent environmental performance requiring over 60 percent less energy for its production than PUR, and releasing over 80% less CO2.

Conclusion where it condenses into the adjoining insulation material. If the condensation spreads through the insulation, thermal efficiency is lost and corrosion and consequential secondary damage will result.

A common problem with pipe support brackets is that they compress the insulation. This can place the copper and steel in closer contact (galvanic corrosion) as well as causing a loss of energy efficiency. That’s why pipes in refrigeration and air conditioning applications must always be isolated from their mounting element with an adequate closed-cell insulation thickness, taking into account the line temperature, pipe size, ambient temperature, relative humidity conditions as well as halogen and nitride content of the material. It is important to use pipe support hanger brackets that do not compress the insulation and maintain the same thickness along the length of pipe.

Within hot water systems there can be significant heat loss as a result of uninsulated pipe brackets or, again, where the material has been compressed, with the consequences being increased energy costs. The extent of this loss of energy can be significant with thermal heat flow calculations for a 60°C hot water pipe in continual use showing a heat loss of 0.06 w/k per bracket (on a 26.9mm diameter copper pipe with a 27mm insulation thickness). This can have a major effect in total energy costs of running a building especially where a large number of supports are used.

A system-based approach of installing pre-insulated pipe support brackets that prevent the crushing of insulation can result in significant energy savings. For example, when Armafix Ecolight supports are used with the equivalent insulation tube thickness, the required insulation is maintained to provide an energy efficient system. This improves the energy efficiency of both hot and cold pipework, with an annual energy saving of approximately £2.50 to £5 per bracket. This quickly adds up

when you consider that a pipework system in a large installation may incorporate hundreds of pipe supports.

A reliable connection between the clamps and an ArmaFlex insulation can only be achieved by sourcing a compatible pipe support from the same insulation manufacturer, because it ensures matching nominal wall thicknesses and system performance. This requirement has driven advances in pipe support systems and some of these, such as our Armafix Ecolight are able to support and protect the insulation from being crushed or damaged, maintaining the thermal integrity of the system. These pipe supports are now being widely used wherever foam insulated pipes require suspended support.

Sustainable materials There has been much work done on improving the sustainability of materials in the building services industry, which is one of the reasons why our pipe supports are now made from 100% recycled PET plastic bottles. This is an extremely environmentally friendly material with a low thermal conductivity and a high compressive strength.

They incorporate PET load bearing segments with ArmaFlex insulation on the outer part for connection with the adjoining insulation material.

This approach avoids the pipe coming into direct contact with the bracket and eliminates crushing of the insulation.

In terms of mechanical performance it eliminates cold spots and prevents condensation forming on refrigeration and air-conditioning service pipework. By helping to control condensation, the risk of corrosion and

We can see that pipe brackets represent a potential weak point in both hot and cold pipework systems. If the pipe is not thermally isolated from the pipe bracket, thermal bridges causes condensation or heat loss, as does crushing of the insulation by the bracket hanger.

Most designers understand that the presence of different metals in any element of a building can result in galvanic corrosion. All metals react with their environment, although some are more reactive than others. Knowing this, and factoring it in at design stage can avoid issues with the HVAC system.

That’s why insulating both pipework and pipe support brackets plays an important role in maintaining system efficiency and integrity. An integrated approach, where the insulation materials are from a single source offers greater compatibility in terms of condensation control, fire behaviour, energy saving and ease of installation.

Model behaviour

Information science has the power to revolutionise the way an HVAC business operates.

Wayne D’Aranjo, marketing manager at Brymec, examines two specific digital developments and assesses their impact on the sector.

The digital landscape is changing as initiatives like Industry 4.0 becomes more firmly entrenched. Industry 4.0 – the fourth industrial revolution in manufacturing, where cyber-physical systems link real with virtual objects via the internet – has been around since 2010 but has only recently captured the imagination of business. It was preceded by: ° Industry 1.0: End of 18th century – First mechanical loom and steam engine. ° Industry 2.0: Start of 20th century – Mass production assembly line and electrification. ° Industry 3.0: Start of 1970s – First programmable logic controller, computer, automation and IT.

June | July 2019

Brymec.indd 36

Industry 4.0 is an enabler for the ‘Industrial Internet of Things’ which connects and integrates industrial control systems with enterprise systems, business processes and analytics.

Digitisation involves creating a digital ‘bits-and-bytes’ version of analogue/ physical things such as switches and controls. We are already witnessing smart devices being installed into homes and businesses, including intelligent personal assistants, smart security systems, smart thermostats and related controls.

"The development of the digital world is set to accelerate. A decade from now, almost all devices will probable be capable of internet connection"

Dramatic change And the development of the digital world is set to accelerate. A decade from now, almost all devices will probably be capable of internet connection and connected predictive and preventive maintenance will be the norm for all key building services including HVAC. Buildings are likely to be able to interface to the power grid in a more dynamic and flexible way with onsite generation and storage of power and the ability to shift demand patterns.

But, although change over the next 10 years will be dramatic, technological shifts are already starting to happen now.

Online purchasing and Building Information Modelling (BIM) are two practical examples of greater digitisation in the HVAC sector and both are set to revolutionise the way the sector conducts its business in future.

Website design can have an enormous impact on efficiency and effectiveness, especially when it comes to ordering components and products. Of course, Amazon showed the way in online retail, but business-to-business sites are now catching on to the benefits of internet supply.

"BIM is a way or working rather than a tangible object. It is the process of delivering and operating built assets using structured digital information to which all members of the project team have access"

My own company, for example, has recently upgraded its website to make it more intuitive and responsive with a host of features. The site saves customers’ time, money and hassle by making it easier for them to find and purchase the right products and reference technical information.

Big advantages Customers can also streamline their processes by creating quotes, favourite lists setting up approval chains that mirror their procurement practices and tracking orders from inception to sign-off.

The site, which is designed to work seamlessly across all devices, including PCs, tablets and smartphones, allows customers to view tailored pricing and receive bespoke offers. It also incorporates a search engine that filters product categories, brands and dimensions.

Powerful account management features allow customers to search orders, invoices and proof of delivery; pay invoices online, and set up a purchasing structure and teams in specific account areas. This means they can delegate authority to team members to raise requisitions and/or place orders.

Websites, however, are not the only digital innovation. BIM is the ‘virtual’ modelling and management of a building project throughout its lifecycle in a single building information model.

BIM is a way of working rather a tangible object. It is the process of delivering and operating built assets – which include buildings, bridges and roads – using structured digital information to which all members of the project team have access.

It does this by generating and managing digital representations of physical and functional characteristics of places.

It offers big advantages to those involved in a HVAC project. For example,

it encourages collaboration among project team members and allows project information to be clearly structured and easy to find in one place. This enables project teams to deliver higher quality buildings more efficiently.

But the benefits don’t end there. It also ensures end users are better able to understand how their buildings are performing so that they can improve that performance. And it brings predictability to a project, both in terms of delivery and operation.

Refined and upgraded Furthermore, it helps to save money and the environment by eliminating wasteful processes and activities and results in fewer errors and reduces rework. Finally, it minimises conflicts and changes during the construction process.

Although it is based on a digital system able to produce drawings, BIM is far more than just computer-aided design. It can, for example, also store architectural, engineering and construction information about a project which can be shared among every member of the project team.

And the dynamic digital models that BIM produces can be used to refine the design, produce ‘what-if’ scenarios, detect potential clashes, or validate performance.

BIM is constantly being refined and upgraded. For example, my own company is increasing ease of access to BIM by linking to BIM Objects produced by its suppliers.

By attaching these links to its website, Brymec is able to bring BIM straight to the customer. It is also going a stage further, building a cloud platform where all these BIM Objects will be hosted in a central and easily manageable format.

H U MID IF IE R S

Full steam ahead David Todd hears why the chance to team up with UK manufacturer Vapac was too good to turn down for Humidity Solutions.

When the opportunity arose to become the exclusive UK distributor for the Vapac range of electrode boiler steam humidifiers, it was an easy decision for Leatherhead-based Humidity Solutions.

Vapac is part of Nortek Global HVAC, which also includes the Reznor and ServerCool brands, and was looking for the best way to return to the market following a fire in June last year that destroyed its factory in the West Midlands, along with stock and spares.

John Barker, managing director of Humidity Solutions, said: “The chance to work with what has been the name for electrode boiler humidifiers in the UK over the past 40 years was too good an opportunity to pass by. Think Hoover for vacuum cleaners, think Pepsi for cola drinks, and you have an idea of the dominance of Vapac. So it’s with great pleasure that we have taken the opportunity to add our application knowledge, system design and after-sales support to complement the manufacturing of Nortek and the Vapac brand.

“Vapac being manufactured in the UK was also an important factor. Removing currency fluctuations and international delivery will allow us to ensure that the units are competitive and a great investment.’’

His thoughts were echoed by Kevin Hartshorne, sales manager of Vapac, who

June | July 2019

Humidity Solutions.indd 38

said: “We are delighted to have Humidity Solutions to partner us in presenting Vapac back to the market after a turbulent year dealing with the disaster of the fire.

This wiped out production for a number of months but our plan has always been to come back even better and stronger with our great product, and now the extra service and support offered by Humidity Solutions.’’

Quality of product John Barker said humidity control's relevance to so many sectors was why he still found it fascinating after 31 years in the business.

He described how a recent typical day began with a trip to an artisan meat producer, Chiltern Charcuterie, that processes meat products to increase the value and create salamis and cured meat. The new drying room requires dehumidification when a new ‘wet’ product is introduced into the store, followed later in the process by humidification, to prevent the outer surfaces of the salami from drying too quickly. Using a controller to operate both systems, an ideal 85% humidity was achieved.

®

Next stop was Lightning Source, a highvolume book producer using digital print.

It produces over 5million books a year on a print-and-demand basis, making books ordered online available for delivery within hours. Again, humidity control is essential in creating the conditions required to achieve these volumes and eliminate significant amounts of waste. A stable 50% humidity prevents the paper from drying out, stops paper curl and cuts static, enabling machine speeds to be kept high and ensuring quality of product.

The final call of the day was to a contractor that specialises in clean rooms, Modern Scientific. Humidity Solutions was asked to advise on producing an environment at a university that requires very close control in an area where medical experiments will be taking place.

Humidity Solutions says it is keen to develop working relationships with more air conditioning contractors and would like to see them embrace the technology by taking advantage of more than 100 years of combined experience at the company.

John Barker said: “Often air conditioning contractors or M&E installers are unfamiliar with humidifiers or humidity control so turn projects away that may involve these products. We are happy to be the support required to allow contractors to take on these projects, whether that be by offering telephone support, on-site design assistance or installing the equipment on their behalf.” www.humiditysolutions.co.uk

The Vapac range

Best of British The new partners say that the knowledge and expertise of both companies will combine to enable Vapac humidifiers to be offered to the market with the full package of support services.

Humidity Solutions after sales director Rob Luddington said: “The number of Vapac units installed across the country is testament to the quality and ease of maintenance of the humidifier. Vapac is the industry word for electrode boilers and we have certainly found them to be reliable and a great unit for HVAC operations.’’

Humidity Solutions will run training and familiarisation courses at its Leatherhead HQ with Vapac units in operation.

Training on site or at companies’ own offices/factory can also be arranged on request. It is offering free design, site surveys and quotations, with a full range of after sales services including installation, technical support, servicing and planned maintenance.

As well as providing comprehensive service solutions, the company is also happy to support HVAC contractors with technical advice, spares and new units.

The LE and LEP electrode boilers are designed for comfort/close control humidification and are available in nine capacities, from 5-110Kg/hr steam generation They feature the VapaNet control system, making it easy for the user to access instant information about the performance of the system.

The LE comfort control model offers humidity control of +/-10% and the LEP close control model +/-5%.

A room distribution unit, compatible with both, is aimed at applications where AHU or ducts are not available.

The LMV Vapa Lite promises simplified humidification for light commercial applications, with either 2Kg/hr or 4Kg/ hr steam generation capacities. It is designed to be used alongside all heating systems in small commercial premises to maintain the required humidity levels during colder weather.

The Vapa Lite again features the VapaNet operating system and can utilise a room distribution unit, mounted directly on top, to operate without a ducted air distribution system. A small fan within the RDU blows steam into the room.

The Vapac VS range of steam room generators is designed specifically for use with steam rooms in the UK, and comes in five sizes, producing from 9-55 Kg/hr of odourless steam.

The controller incorporates on/off room light switching, volt-free contact to provide interlock for an essence pump and cylinder change warning light. Operation is fully automatic and the manufacturer says the generator is simple to maintain.

Is the refrigeration industry underselling itself?

As World Refrigeration Day approaches, Ed Whinyates of Stonegrove Refrigeration backs the call to shout more about what we do.

When I am asked by someone outside of the refrigeration industry what I do for a living, one of the first things people say is “… so you sell fridges?” Like a tall person being asked “what’s the weather like up there?” I politely laugh along. However it has me thinking about the disservice to our industry. Modern living relies heavily on refrigeration; people wouldn’t question the important role of fridges, freezers and air conditioners. But refrigeration appears to be taken for granted and undervalued. The big question has to be why?

It is estimated that the total number of refrigeration, air conditioning and heat pump systems in operation worldwide is roughly 3 billion. These are spread across many sectors of industry and society.

The sector that most people will have probably experienced refrigeration for is food and beverages. Whether it is the chilled and frozen aisles in the supermarket, or a domestic refrigerator, you will be hard pressed to find an adult or child in the western world that hasn’t been exposed to refrigeration in one form or another. But this doesn’t even get close to the amount of refrigeration required to keep perishable goods from spoiling.

Fresh product from abroad has to be stored within temperature controlled facilities.

There is also the transportation of product (be it by land, sea or air) that needs to be temperature controlled – and this can only be achieved by refrigeration.

Even before it gets anywhere near a

June | July 2019

supermarket, a vast amount of processed and manufactured food material needs refrigeration. Both during the making and preparing of the product, and for its storage post-production, refrigeration is fundamental in maintaining food safety and nutritional qualities.

Flowers, plants and bulbs also need refrigeration. It is no coincidence that on certain days of the year (and the week or so leading up to it) that the shops are flooded with bouquets of flowers from suppliers.

They are carefully grown and maintained in a proper environment, underpinned by the cold chain of refrigeration.

Clever use Another area that impacts on people’s day to day lives is within the healthcare sector.

Refrigeration preserves pharmaceuticals

and medicines. These include - but are not limited to - vaccines, blood, insulin, transplant organs and the freezing of human embryos. Research and development has also benefitted from refrigeration.

Treatments, such as cryosurgery or cryotherapy, were developed due to ultralow temperature technologies.

Refrigeration is also at the heart of science and major scientific projects.

The Large Hadron Collider (LHC) – the world’s largest and most powerful particle accelerator – uses a 27-kilometre ring of superconducting magnets maintained at -271.3°C thanks to superfluid helium; this gives access to the high energies needed

to test fundamental theories of particle physics. Even up in space, satellites require cryogenic cooling and refrigeration. The scientific search for limitless energy at the International Thermonuclear Experimental Reactor (ITER) requires temperature control. This machine uses very large superconducting magnets and cryopumps which are cooled to assist performance. Even smaller unusual experiments have benefitted from refrigeration - such as the clever use of refrigeration to fight bee colony collapse.

Major sectors of industry need refrigeration in many forms. For example, in chemical and petrochemical industries, large scale cooling plants are used in their processes. The control of temperature is an important factor in reaching high efficiency in their transformations. Distillations, crystallizations or condensations are operations requiring the removal of heat - so refrigeration systems are necessary to obtain their products. The plastic and building industries also need refrigeration.

Data centres need refrigeration. Since servers and other equipment do not perform very well in extreme temperatures, most data centres have huge cooling and air flow systems. All IT networks need a data centre, so the growth and daily use of computer data storage is reliant on maintaining temperature.

More recognition There are other areas of daily life that rely on refrigeration, ranging from the comfort cooling of buildings, leisure facilities and sporting stadiums, through to air-con in transport (cars, trains, aeroplanes etc.).

People wouldn’t be able to experience winter sports in snowdomes and ice rinks without refrigeration.

Because of all of all of these sectors (as well as others I haven’t got the space to

mention here), we cannot underestimate the major and increasing role that refrigeration plays in today’s global economy. It is also estimated that circa 12 million people are employed worldwide in the refrigeration sector so, economically, the importance of refrigeration is paramount.

There are people within the refrigeration who are trying to promote and get more recognition for this important, and quite frankly, brilliant industry. A good example of this is World Refrigeration Day – the first of which will be celebrated on June 26.

Refrigeration is now an essential part of our daily life, and ingrained in everything we do, so why not shout about it a bit more? And if I can get my kids to read this article then maybe they’ll stop telling people “my Dad is a fridge salesman”!

Rapid response cooling solutions Breakdowns can be catastrophic for cold storage warehouses, and require a fast and effective response to avoid the damaging consequences associated with rising temperatures in rooms where products are stored. Matt Watson, sales manager at Aggreko, explains how emergency cold storage units offer warehouse owners and operators a swift, reliable solution in these circumstances.

Cold stores can contain millions of pounds worth of stock at any one time and are reliant on chilling systems to keep air temperature at -22°C or below, ensuring product integrity. If these systems were to break down, any influx of ambient air into the cold store can have a major detrimental effect on this stock. Indeed, if store temperature increases by just a few degrees any stored frozen goods may need to be thrown away, at large financial cost.

Faced with this situation, it is standard practice for store managers to lock the store down to preserve cold store temperature for as long as possible. If locked down, the store will hold temperature for a number of days, but would have a detrimental effect on the supply chain served by the cold store. This time window is absolutely vital if the integrity of the cold store is to be maintained and its products kept in optimum storage condition.

Traditional option The traditional option in these circumstances is to opt for a refrigerating solution that involves installing chillers,

and hoses outside the cold store site, with several air handling units installed inside.

However, installing such a solution can take two to three days, and during this time temperature within the cold store will be continually rising.

Consequently, though the new installation may ensure the store keeps running with temperature restored to -22°C, clients may still have to throw products away unless they act extremely quickly once system failure occurs. Yet because breakdowns are often sudden and unexpected, it is difficult to guarantee this immediate, planned response ahead of time. As a result, warehouse owners and operators are likely to end up disposing of thousands of pounds worth of now-spoiled stock if such a situation were to occur.

Emergency cold storage This risk of product spoilage can be avoided through the use of temporary air-cooled low temperature DX units. Aggreko, for example, offers a plug-and-play solution housed in a 20ft container, which is a direct expansion unit that delivers 100kW of air

at -22°C, all housed within a single unit.

Crucially for cold stores, solutions such as these are designed for rapid response, offering a quick and easy installation for freezing and cooling store rooms. One of the benefits of emergency cold store units is the time saved on installation. It can be deployed quickly and installed in hours once on site, returning affected storage rooms to regular chilling temperature. This means regular warehouse operations can be resumed without affected frozen or chilled goods having to be thrown away or decanted into another cold store.

Furthermore, these emergency cold storage units can be used to carry out multiple processes, depending on what processes are used on site. This includes blast freezing – quickly cooling down hot products such as food to ambient temperature or below extremely quickly so they can be packed without sweat occurring inside the wrapper.

These units can also be used for holding chill scenarios, in which a product is moved in its frozen state into a holding freezer, where it can be kept for prolonged periods before being supplied to the customer.

Furthermore, the unit can be utilised for chilled storage operations, delivering 100kW to maintain air at 0°C, ensuring chilled foods remain at refrigeration temperatures.

Unique alternative Due to its unique concept, this solution does not take up valuable space inside the affected cold or chill Store. All setting and operating can also be made from outside, and the unit can be converted into a watercooled system if there is no space available to install it externally.

By contrast, a traditional solution requires the installation of both external and internal equipment. These parts, including chillers, pumps and hoses, may take up valuable space within what can be

demand will spike, or to safeguard against uncertainties such as Brexit. Increasing storage capacity without installing further chillers and chilled air distribution systems could place added strain on existing plant infrastructure, making a breakdown more likely.

By implementing a temporary solution, it would be possible to transform a regular, ambient-temperature storage space into a cold store and ensure the warehouse meets required temperatures for these busier periods. Crucially, these temporary units adhere to appropriate industry standards surrounding chilled and refrigerated products, so cold storage warehouses can increase capacity when required quickly, safely and easily.

Final thoughts

a very tight environment. Consequently, this can lead to a more costly, lengthy and logistically complex installation at a time when speed and simplicity are a priority.

Indeed, because these units can be installed much more rapidly than traditional solutions, emergency cold storage units can give owners and operators more time to consider their next step following a system breakdown.

Additionally, Aggreko’s fleet of temporary power generators means that if the site us unable to provide access to mains power the additional capacity required for the unit can be supplied as part of any installation.

Further functionality Temporary air-cooled low temperature DX units are not only limited to use during breakdowns and emergencies. They can also be used as a temporary cooling solution during planned shutdowns, allowing the cold store to continue operating while a fixed cooling solution is being maintained or upgraded.

Beyond unplanned and planned shutdowns, these units can also offer an excellent option for companies looking to stockpile products. For example, a cold storage warehouse operator may wish to increase their capacity to store food and pharmaceutical products for periods where

Companies who rely on cold storage warehouses can face two main risks – a lack of capacity during periods of peak production and high demand, and the possibility of system failure. Emergency cold storage units that are available for hire can also be delivered and installed at short notice, meaning production is not impaired and customers can avoid issues that may arise around product spoilage, and its ensuing costs.

Emergency units are also ideally placed to assist companies looking to improve their chilled storage capacity temporarily, putting retailers, manufacturers and warehousing sector professionals’ minds at ease.

Setting new standards Manufacturer believes low energy consumption of ammonia freezer can revolutionise cold storage and food processing.

Star Refrigeration says its new generation of industrial pre-packaged low charge ammonia freezers are unique in the industry and set a new benchmark in annual operating efficiency.

Designed for food processing and temperature controlled storage applications, the Azanefreezer 2.0 is charged with as little as 0.52 kg/kW of ammonia. ​A European study from the International Institute of Refrigeration showed average European energy consumption figures for chilled and frozen storage facilities across Europe were about 50% higher than the figure declared to be “Best Practice” by the UK Government. However, Star says that recent energy performance data analysis for Azanefreezer 2.0 indicates its annual energy usage is one-third of that of the UK’s ‘Best Practice’ guidelines.

Rob Lamb, group sales and marketing director at Star Refrigeration, said: “We’re really excited about the launch of Azanefreezer 2.0 because the stunning improvement in energy consumption sets a new benchmark landscape for freezer performance.

“As a pre-packaged low charge ammonia freezer, the Azanefreezer 2.0 is completely unique in the industry.”

The Azanefreezer 2.0 uses onboard PLC hardware and software to deliver optimised

system efficiency including compressor sequencing and condenser and evaporator EC fan speed control. It also takes advantage of the variable Vi capability of the compressor by using an air-cooled condenser and allowing the discharge pressure to drop extremely low in cold weather, thus improving the seasonal efficiency of the system.

Additionally, Star’s patented 4-way valve also delivers a rapid reverse cycle defrost, using less energy than electric or hot gas systems.

The low charge ammonia design reduces

refrigerant charge by up to 96% compared to traditional ammonia systems and avoids the need for complex valve stations within the cold storage or food production facility. This removes the requirement for leak detection and ventilation, minimising health and safety concerns.

Ammonia has no harmful global warming effect and delivers efficient operation across a wide range of operating conditions, helping end users to reduce their carbon footprint and energy costs.

With UK government emission conversion factors of 283 grams of carbon dioxide equivalent per kilowatt-hour, data from a recent Azanefreezer 2.0 installation indicates the cold storage operator is set to cut carbon emissions by 453 tonnes

of CO2 per year compared to the ‘Best Practice’ guidelines. This saving rises to 815 tonnes of CO2 per year when compared to the typical cooling demand of similar operational cold stores across Europe.

The Azanefreezer 2.0 is available in capacities up to 650kW and delivers temperatures down to -40°C. For larger capacity installations, multiple units can be used for cold storage and blast and spiral freezing applications.

It is manufactured and precommissioned at Star’s production facilities in the UK. When delivered to site, installation and commissioning time is said to be reduced significantly due to the unit’s plug-and-play design. www.star-ref.co.uk

Work begins on distribution centre ISD Solutions has started work on a new distribution centre in Scotland for frozen foods supermarket chain Farmfoods.

The warehouse in Cumbernauld will have more than 17,000m2 in floor area in total and will incorporate a -22°C freezer, a +4°C chiller and an ambient storage area.

Requiring 29,000m2 of Kingspan Composite Panel, the cold store will feature 15% ambient rooflight coverage to supply the warehouse with natural light and a one-hour fireproof separation wall as a passive fire protection measure.

It is not the first time that the two companies have worked together. In 2014, ISD Solutions created a freezer, chiller and dry storage distribution centre of similar size at a Farmfoods site in Avonmouth near Bristol – close to ISD’s home in Gloucester.

The Cumbernauld project marks the latest in a series of works that ISD Solutions has undertaken in Scotland and the company is keen to win more business there, with Martin Paul recently appointed to head up a new Glasgow-based office.

Richard Bowden, director of the company’s Special Projects Division, said: “This work in Cumbernauld is a significant project for us, with a considerable amount of composite panel to install with precision and competence. And with the roof lighting and firewall installations requiring further technical expertise, it’s an exciting scheme to be involved with.”

Willie Scanlon, head of property development at Farmfoods, said: “For almost 40 years Farmfoods has had offices and a distribution depot in Cumbernauld. I’ve had

the good fortune to have been a member of the team for most of that time. As a business we’ve simply outgrown the current setup here and it has become operationally inefficient. This new development will see us secure and greatly improve our future here for many more decades.

“This is one of the largest projects we’ve undertaken and we chose to partner with ISD having previously worked together during the construction of our Bristol depot in 2014. It brings me great personal satisfaction to be involved in such a huge project and having the right team around us is critical.”

Tools Talk.indd 46

The fact that the UK operates both single phase and three-phase electrical supplies with different voltages can prove tricky for engineers when it comes to recovering refrigerants since it means having two different units, one suitable for each voltage. To overcome this, the innovative JAVAC XTR-Pro-DV A2L has a simple switch which allows engineers to change the unit to suit the voltage, it can easily be switched from 115V to 230V as required.

This is very convenient on site since it means engineers don’t have to carry two recovery units in their vans.

This high performance, innovative refrigerant recovery unit is designed with ground-breaking X-Connect technology which protects the XTR-Pro-DV A2L’s vital components against the damaging effects of incorrect voltage, another industry first. There is also an integrated circuit breaker providing additional protection. Designed specifically for systems where A2L/R32 gases are in use, the XTR-Pro-DV A2L’s spark proof design features a 5m hard-wired cable - critical when dealing with new mildly

flammable A2L refrigerants. The dual voltage switch, X-Connect technology and integrated circuit breaker all improve safety and protect the unit from damage.

Gourmet cheesemaker opts fo r Cheesemaker Woerle has installed a state-of-the-art BITZER ammonia refrigeration system at its Austrian factory, to deliver high efficiency zero-GWP cooling.

Woerle is world-renowned for its gourmet cheeses, which it produces by natural methods from milk sourced from organic farms across Austria. It has now complemented its natural approach to food with a new refrigeration system based on award-winning modern ammonia cooling technology from BITZER. Ammonia is arguably one of the greenest and most natural refrigerants available.

Although made through industrial processes for use in refrigeration, ammonia is one of the few refrigerants that occurs naturally in nature It is part of Earth’s nitrogen cycle and is produced in soil as a result of decomposition of organic matter. This contrasts with synthetic fluorinated refrigerants, which are entirely man-made and do not occur naturally in Earth’s ecosystems.

In environmental terms, ammonia has impeccable credentials. Both the Ozone Depletion Potential and Global Warming

Potential of ammonia is zero. This, combined with its inherent efficiency, means it has the lowest Total Equivalent Warming Impact (TEWI) of any refrigerant (where TEWI is the sum of the direct and indirect effects of an ammonia system on global warming over its lifetime).

Benefits Due to its thermodynamic properties, ammonia is highly energy efficient, requiring the lowest energy input of any refrigerant to produce a given refrigerating effect. Not only are ammonia systems efficient and cost less to run than competing systems, but the refrigerant itself is relatively inexpensive, even in the high-purity grade required for use in refrigeration.

Recognising these benefits, Austrian cheesemaker Woerle recently installed three BITZER Ammonia Compressor Packs (ACPs), marking the company’s first foray into modern ammonia cooling.

Delivered by supplier and contractor Herzog Kälte-Klima, the units are required to deliver liquid coolant at -12°C and ice water to +2°C for use in cold stores, ventilation systems and process cooling at the manufactuer’s Henndorf site near Salzburg.

The project required meticulous planning due to the scale of the combined equipment. Each ACP system is around 2.2m long, 2.7m wide and 2.3m high, and weighs around seven tonnes.

Six members of the contracting team were responsible for managing logistics and safe delivery of the packs. This included the crane operator, banksmen for the truck and installation site, plus three installers for securing the lifting equipment and disconnecting the load.

With a radius of up to 35m, a 220-tonne crane lifted the ACPs approximately 20m into the air before lowering them through an opening into the plant room, where they were manoeuvred horizontally into their final position.

The independent verification specialists reviewed the system design and carried out a pipework and process inspection in accordance with the Pressure Equipment Directive, including X-ray testing of weld seams. They also conducted a nitrogen pressure test prior to charging with ammonia, and a final electrical test of control systems.

Project manager Herbert Khier, who oversaw the installation, said: ‘We at Herzog have been working with BITZER products for 40 years, however we have rarely had much to do with ammonia systems. However, they are now becoming increasingly popular. Our customer Woerle was familiar with the name BITZER, and ultimately it was the outstanding value for money that led the company to opt for BITZER ACPs. The ‘Made-inGermany’ label also carries a lot of weight here in Austria.”

Maintenance

BITZER manufactures its ammonia compressor packs in Rottenburg-Hailfingen in southern Germany, with the screw compressors on which they are based produced at the company’s factory in neighbouring Rottenburg-Ergenzingen.

Standard ACPs contain two or three OSKA95 screw compressors, plus a threestage horizontal OAHC oil separator. For the Woerle project, BITZER offered ACPs with just one compressor with the option to expand in future.

Efficiency performance is optimised by the use of frequency inverters and two -pole high-speed motors, each with an output of 315 kW and a maximum speed of 4,200 rpm.

A further benefit for end users is that screw compressors have much longer maintenance intervals than reciprocating compressors, which substantially reduces the cost of ownership over the life-time of the plant.

For the contractor, the carefully-thoughtout ACP design allows ready access to valves, sensors and connections for ease of installation and servicing, and the unit comes equipped with Wi-Fi connectivity and full Modbus integration.

The design features controller and sensor redundancy to enhance reliability, while the stand-alone control panel has number cable-tree to assist installation.

Woerle’s BITZER ACPs were commissioned in April 2019. www.bitzer.de/gb/en/

Installation The horizontally mounted units were lifted using a vibration-reducing machine base and then horizontally transported by the installers. The process required heavyduty castors, lifting cylinders and jacks for transport inside the plant room.

Once the packs were safely deployed and positioned, the installation team took over.

This comprised a welder, two pipe fitters and an electrician, with the installation process monitored by certification body TÜV.

How is your equipment faring?

ThermOzone director Trevor Dann explores the potential benefits of extending the lifespan of equipment.

Following on from the demonstrations by protesters in London and the speech to Parliament by teenager Greta Thunberg, concerns for the threats from climate change are currently in sharp focus.

Our own industry remains a significant user of the total energy in the UK, and much of the equipment we rely upon is either poorly appointed as far as energy efficiency is concerned, or has far too short an effective lifespan, with manufacturing focus concentrating upon the surface aesthetics and minimal manufacturing cost leading to minimal supply price. Most of this equipment is also imported. A lesser focus is given to operating energy efficiency, and virtually nil attention is provided to the resource mining and energy, manufacturing process energy, nor shipping impact.

The fuller list of environmental concerns, including operational energy, should also consider: Life energy ~ % Raw material, mined resources & energy to recover these

OK, so this model is somewhat simplistic.

For instance, the operational energy impact will increase with longevity, so direct energy efficiency has a greater impact the longer an item lasts. But the sample provided here is a perfectly reasonable representation of the overall impact.

What is a respectable target for equipment longevity?

Clearly the longer an item of equipment lasts, the life energy per annum figure drastically reduces.

Since the late 1990s the refrigeration industry has largely converted to Scroll compressors, with a reliable service life ~ 8-10 years, and for much equipment and with lack of effective service at the 8-10 year life point, the compressor lifespan equals the reliable equipment lifespan.

Scroll compressors offer a moderate level of efficiency (~4), but generally unattractive when compared with say Turbo or Inverter Screw efficiencies (~5). Turbo machinery is rather specialised as far as general application is concerned, but Screw compressors are highly effective from base loads of just 30 kW to >2 MW. Many larger applications now use multiple Scroll sets, where for a little more initial investment hardy Screw compressors would easily see equipment longevity

increase to ~ 20 years. A screw compressor may need new bearings at the 10-year point (higher run hours equipment), but generally this means the overall equipment will remain in service for an intended 20 years target.

It is certainly the case that the vast majority of larger equipment, such as chillers, our own specialisation, go to the scrapyard with an easy solution available to life extend. Just last year we retrofitted three 1988 York chillers, each of 650 kW capacity, to new equipment standard, with a further life expectancy of 20 years. These chillers will be 50 years old when they reach their re-designed life point. OK, so we replaced all functioning components but we saved ~ 50% of the machine mass of materials forming the base chassis.

We also achieved an expected efficiency (equivalent to Eurovent ESEER standard) of ~ 5.0 and by use of lower GWP refrigerant R513A we also cut the original CO2 tonnes

of the refrigerant to 1/3 the previously appointed R22. The before to after energy saving average seasonal use is > 60%.

The icing on the cake for this project is the full remote service access, allowing us to continually tune the equipment to optimise efficiency throughout the year.

Remote access Equipment standard operation results in assigning setpoints for reliable service despite an operating ambient temperature range of ~ 35°C. No piece of equipment can work at optimum efficiency both at -5°C and +30oC, so the result is a compromise for the overall efficiency. Yet some simple seasonal adjustments will achieve stable

operation in the cooler months, with optimum energy effectiveness when the plant is working its hardest.

Remote access is an area wide open to improved service effectiveness for many clients, especially those with larger equipment. With remote access the concept of the ‘Virtual Service’ and with it the ‘Virtual Call Out’ have been developed.

Reviewing equipment performance each month builds up a trend and allows any issues to be spotted early, preventing secondary deterioration from minor faults and failures. When a fault does arise attention can be applied swiftly, indeed for the numerous chillers we have on remote access, and now with email alerts upon fault, we expect to be examining a machine in fault within ~20 minutes. Faults arising during the working day can be responded to within <10 minutes.

When we introduced the RODEM system we operate we expected that remote service access might reduce call out attendances by ~30 - 40%. After five years we now believe RODEM has actually reduced physical attendance by ~85%.

Unrivalled efficiency RODEM monthly checks also reduce the need for physical routine attendance.

Instead of the increasingly rare resource of an experienced service technician spending much of his day getting to a site, then spending his time measuring this and that, we are seeing the performance, in fine detail, in an instant. We can achieve in a 20-minute remote ‘Virtual Service’ the same level of scrutiny, if not higher, that an experienced engineer will achieve in a

51

3-4 hour service visit. We can even see the direct effects of a leakage, although we do not promote RODEM as replacing the statutory requirement for physical leak checks. We have found that for most sites the physical service effort is now just the physical leak check, clean down of the equipment, plus an annual calibration and cable tightness check of the various sensors.

The cost of RODEM is outweighed by its benefits by a factor of ~2. The direct savings for a typical four visit service contract reducing to two visits to satisfy F-Gas requirements pays for most of the service. Further gains of increased reliability, reduced downtime and optimised efficiency provide the other gains compared with non-remotely accessible equipment.

RODEM assigned with a new project also massively improves the set to work process. No longer are we sending an engineer back to site to deal with nuisance teething adjustments, we can view the machine’s operation throughout the day, from anywhere there is a Wifi signal. Now the ‘soft landing’ process extends throughout the warranty period and beyond.

So for us 10 years is the minimum life point extension for minor refurbishments, with our primary target being 20 years for new installations, and at unrivalled energy efficiency and service support levels. All our projects offer 40% or higher equipment material re-use, the simplest form of recycling.

The R32 success story A-Gas product manager for refrigerants, Roger Smith, on how the industry has risen to the challenge and adopted this new refrigerant as a replacement for R410A. The news that air conditioning manufacturers are unveiling more new equipment able to run on R32 highlights how the industry has changed. R32 with its low GWP hit the headlines three years ago as an emerging refrigerant which was a practical alternative to the high GWP R410A. The F-Gas Regulations state that from 2025 any gas with a GWP higher than 750 will be off limits in low-charge split air conditioning systems. R410A is a legacy gas with a GWP of more than 2000. R32 is a single component, zero ODP gas with a GWP of 675. Other advantages associated with R32 include the benefits that the cooling capacity is much higher and the equipment needs a much smaller footprint.

In some respect it has been no surprise that the uptake of R32 by major manufacturers has been one of the success stories of the F-Gas Regulations’ phase downs. After a slow start, R32 is now a popular choice in new AC split systems.

Manufacturer after manufacturer has announced that R32 will now be the mainstay product in splits despite the fact that there’s more than five years to go before the 750 GWP deadline is with us.

June | July 2019

A-Gas.indd 52

Many manufacturers have embraced R32 fully on splits and have now upped a gear to offer R32 on the much larger hybrid VRF systems. Moving forward with the phase down of high GWP products manufacturers have, quite correctly, taken a view of let’s get on with it now rather than wait until we have to take action. They have shown progressive thinking and in doing so have been able to display their green credentials and offer savings to customers.

By its very nature, a VRF system is a larger, more complex installation and under BS EN 378 2016 putting a full charge of R32 into a VRF system is banned. It may take some time before pure R32 features in large hotels and office blocks because of the physical size of these systems.

Volume 5 No.3

REFRIG ERANTS

R32 is an A2L or lower flammable refrigerant and what makes this gas such an excellent alternative to high GWP refrigerants is that typically you will use less product in the system. It is a very stable refrigerant and add to this the smaller line sizes and a potential cut in running costs which can be as much as three per cent a year and you have some very impressive savings to offer the customer.

R32 does require a new approach. Lower flammable A2L refrigerants are not drop-ins and cannot be used to replace nonflammables in air conditioning systems.

Engineers need to be aware of how to handle them and ensure that they have the right tools to do the job. However, the uptake of R32 clearly demonstrates this is not presenting too great a problem for installers who, to their credit, have risen to the low GWP challenge.

A2Ls are very difficult to ignite. Only a naked flame â&#x20AC;&#x201C; and not a spark â&#x20AC;&#x201C; will ignite them as thereâ&#x20AC;&#x2122;s not enough energy in the

"We will be working closely with the contractors to recover and reclaim as much product as possible with the aim to return reclaimed refrigerant to the market"

spark to do so. The amount of refrigerant which would have to escape into the atmosphere also has to be on a much larger scale to reach low flammability limits. That aside R32, like all refrigerants, should be handled with care.

Manufacturers are looking at additional technologies to support and grow the use of R32 in the air conditioning industry. I fully expect to see some more developments soon. But having said that,

53

we have not seen the last of R410A as this refrigerant still has a long life ahead.

At A-Gas I expect that our approach to R410A will follow much the same pattern as it has to other legacy gases, such as R404A. We will be working closely with the contractors to recover and reclaim as much product as possible with the aim to return reclaimed refrigerant back to the market.

As long as it is needed to support existing equipment we will work with the industry to ensure that there will be adequate supplies of reclaimed R410A available.

If you are unsure about how to make the switch to R32, consult your refrigerant or air conditioning equipment supplier. They are there to help and will be able to advise you on the best course of action whether it be a split system or VRF system. From a refrigerant supplier perspective, I have no doubt that R32 and R410A will be significant players in the air conditioning industry for many years to come.

IOR SCOTLAND TARGETS MORE GROWTH

Calum McKenzie is thanked by Julie Murray

IOR Scotland is looking to convert its growing social media following into increased membership, backed by a busy programme of events.

The branch has reached 300 followers on LinkedIn in less than a year, much to the delight of chairperson Julie Murray and the IOR Scotland committee.

Julie said: “Since Lizzie Dunlop came on board to work on the marketing the social media numbers have grown and we want to thank everyone who has followed us. We also try to take the opportunity to ask our followers if they are IOR members and explain the benefits to them.

“Our events calendar is the busiest it has ever been. The Cool Talks in Glasgow and Aberdeen with Andy Butler from Star Refrigeration were really well attended. We also had our first Women in RACHP networking lunch, plus seminars, and the golf day is at St Andrews in August.’’

November 14 will see the 40th annual dinner in Glasgow, with Julie and her team hoping to top the record 406 figure for last year’s event. “We would love to get to 450 to mark the anniversary,’’ said Julie, “and we’d love it if everyone who came to the dinner decided to become a member!’’

After over 23 years of service including two stints as chair, Calum McKenzie has retired from the IOR Scotland committee. The branch thanked Calum at the recent AGM in Glasgow and wished him all the best at Star Refrigeration.

WOME N IN A C R

ACR industry LISA-JAYNE COOK delivery. This includes establishing contact with the customer, carrying out site surveys, selection of cooling equipment, design of associated pipework and controls, creation of system schematics and technical documents as well as coordination of labour and sub-contractors.

What attracted you to the industry?

ACR Journal talks to senior sales and applications engineer Lisa-Jayne Cook, a member of the Women in RACHP steering committee, who recently moved from Aqua Group to J&E Hall.

What was your first job?

My first job was secured through Fareport Training, an apprenticeship/work placement training organisation. I was placed as an office junior/sales support at Bonwyke. This was my introduction into the world of building services, with a leading UK wholesaler and installer of protective window film. It was here that I built the foundations for my future career, completing my modern apprenticeships in Information Technology and Customer Services.

June | July 2019

Women in ACR.indd 56

What did your most recent role involve?

Predominantly sales and design with some project management, too. Aqua Group offers bespoke chilled water systems for process cooling, which encompasses a wide range of applications from plastic moulding processes to MRI scanners. As a sales and applications engineer I am responsible for managing the project from conception to

RACHP isn’t the career I dreamt of while in education (I had aspirations of a life in classical music), but a path I’m glad I chose to follow. I’d seen a role for a draughtsperson advertised at Heating and Cooling Coils but didn’t have any experience in engineering or technical drawing. With some words of encouragement from my mum and the promise of some technical drawing lessons (she was a draughtsperson with an electrical engineering team) I applied, and thankfully they took a chance on me. That was the start of a career that has spanned 19 years, in an industry that I am very passionate about.

What excites/interests you about the industry?

The RACHP world is constantly evolving, and as such is one that requires active engagement to keep up with technology.

Every day is exciting in its own way. Even after all these years I am still finding technical, commercial and application challenges that really require some thought and consideration.

The IOR’s Women in RACHP network, established with the support of the ACR Journal in 2016, now has more than 600 members.

It is open to anyone (male or female) working in an RACHP-related role. You do not have to be an IOR member.

You can get involved through the Women in RACHP LinkedIn group.

Being able to genuinely make an impact on businesses and the environment through energy savings, and to be involved in innovative processes and products, both at Aqua Group and with clients, was truly rewarding. I feel very privileged to work with many passionate individuals who care about the impact of their decisions. RACHP is a fervent, caring and collaborative industry.

How would you like to see your career developing?

I hope to move into a more senior role in the future where I can share the knowledge and experiences I have gained over the last 19 years. To continue the good work the Women in RACHP group is doing by engaging with young engineers and helping them to develop in both their professional and personal capacities. I also hope to continue to be an ambassador to female engineers, particularly in our industry, and to help develop new schemes and incentives to encourage young people into engineering.

What is the best piece of advice you were ever given?

To be honest! Take ownership of your mistakes and be responsible for correcting them. Never be afraid to ask for help and guidance; we can only grow personally and professionally by constantly striving to better ourselves.

What do you see as the challenges facing the industry?

What are the best things about being in your role?

In a world where the environment and sustainability is of ever growing concern the real challenge is engaging with governments, manufacturers and end users on a global scale. To educate on the impact our industry is having when poor choices are made and to prove the desired results can be achieved with the best possible outcome for our planet. We must continue to innovate and develop products, processes and systems that reduce our carbon footprint and minimise ozone depletion.

Other than the environment and our attitude towards it, another big challenge is in the developing world. We need to support, invest and guide developing countries to a better future, where food waste can be reduced, living conditions can be improved and the advances in medicine we are so lucky to benefit from can be shared with them too.

We are seeing a change in attitudes towards energy consumption and its impact on resources, global warming and the environment in general, but there is still a long way to go. We must continue to promote investment in green initiatives and to look to the next generation for fresh ideas and to acknowledge the concerns they have for the future.

The variety of applications we get involved in keeps the role interesting. There are so many opportunities to learn new applications and processes, meaning there is very little time to get bored. Every day really is a school day.

Another benefit is having the opportunity to be involved in ground-breaking projects and to work with some of the country’s most inspiring engineers.

What would you say to other women who are considering coming into the ACR industry?

There has never been a better time to join our industry for women. It hasn’t always been this way, but we are an industry that promotes inclusion and is proud to boast some very progressive thinkers.

The number of women in the industry is growing rapidly, and with our combined forces we can continue to improve our working environment and nurture each other for the benefit of all.

High temperature... high efficiency

Holding capacity helping system to deliver on all fronts for renovation project.

The outdoor unit is compact and offers low noise levels

Flexible solutions

The ‘hydrokit’ indoor part of the system is on the first floor, taking advantage of the allowable elevation difference from its matching outdoor unit, and located in a purpose built plant area within the annexe roof. All control wiring terminates at this single point.

Two different setpoints allow the system to provide domestic hot water as well as central heating. Being able to generate water above 60°C, along with built-in sanitisation programming, meant that third party immersion heaters or other devices were not required to meet storage cylinder regulations for the prevention of legionella.

Jeremy Smith, director of independent distributor LG Comfort Cooling, said: “The LG Therma V product range has been on the market for over 10 years. It is made to deliver solutions that are comprehensive yet flexible. Being involved in this project through providing and supporting the equipment both to Mr Day and AC Engineering has allowed us to make sure extensive support is always available.”

The outdoor unit is largely hidden from sight by a small separating wall and its compact size means planning permission is not required. Low noise levels make it not only environmentally friendly in terms of being a renewable energy source but also produces very low noise pollution.

The elevated indoor ‘hydrokit’ is housed in the annexe roof

A High Temperature Therma V air to water heat pump system from LG is providing heating and hot water to a renovated fivebedroom home in Warwickshire.

Without mains gas to the 100-year-old barn conversion, homeowner Roger Day wanted a system that was simple to use and kind to the environment.

The split cascade system makes use of two refrigerant circuits each with its own inverter compressor, one on the inside of the building and one on the outside. Producing leaving water temperatures of up to 80°C, it is suitable for use with radiators and other heat emitters that require a slightly higher water temperature than underfloor circuits.

Steve Hare, managing director of installers AC Engineering, said: “Underfloor heating wasn’t really an option. Mr Day didn’t want us to lift the floor level as the transitions between conservatories and different levels of the house would have been difficult to navigate. He also wanted to use designer style radiators, so we

selected them based on a 55°C operating temperature.

“Holding its capacity is where the High Temperature Therma V really comes into its own. As opposed to operating at 65°C, its full 16kW capacity is maintained when producing water temperatures at 55°C. This capacity is held all the way down to -7°C whilst still providing excellent energy efficiency ratios. Its selection was critical to match the heat loss calculation for the property, but we avoided the usual problems caused by selecting ‘low temperature’ heat pumps and operating them higher than their 35°C design temperature.’’

Water source of inspiration

Breakthrough scheme will take heat from river to provide heating and hot water.

A pioneering water source heat pump project to deliver district heating was showcased at the recent All Energy 2019 exhibition and conference in Glasgow.

Star Renewable Energy joined partners Vital Energi and West Dunbartonshire Council at the event to raise awareness of the scheme, which forms part of the regeneration of Queens Quay in Clydebank. For the first time in Scotland, water source heat pumps will take heat from a river to provide hot water and heating to a large development as part of a district heating system. The low carbon energy project delivered by Vital Energi is scheduled to be deployed in September.

Two 2.6MW heat pumps will deliver heat and hot water to all of the new buildings in the development and some of the existing public buildings. The heat generated will be pumped through 2.5km of district heating pipe connecting local homes, businesses and public buildings such as West Scotland College and Clydebank Library and over 1,000 new homes. West Dunbartonshire Council has funded 60% of the energy project, which has also been supported by the Scottish Government’s Low Carbon Infrastructure Transition Program (LCITP).

The industrial district heat pump is said to generate heat three times more effectively than gas boilers, allowing it to offer affordable heat with a much lower carbon footprint than fossil fuels. With no local NOx or SOx air pollutant emissions, this is an even more future proof outcome.

Inspiring others Dave Pearson, director of Star Renewable Energy, said: “There has never been a higher profile for low carbon and clean energy beyond the now ubiquitous wind generation. Heating is far more challenging and, done badly, far more damaging to our environment and our citizens. Many have read the recent Committee on Climate Change advice and concluded we should be burning hydrogen in our cities. We believe in deploying known and proven technologies that can be deployed at scale now.

“If we have learned anything from Greta Thunberg’s determined campaigning it is “do more faster” This is what we have striven to do over the last eight years since proving high efficiency, high temperature heat pumps from a readily available

resource of a large river is possible and now in Clydebank we will prove this all over again. With West Dunbartonshire Council and Vital Energi we will spread the word about the successful Queens Quay project, and hopefully inspire others to consider heat pumps as an efficient low cost, low carbon solution for heating systems.”

West Dunbartonshire Councillor Iain McLaren, convener of infrastructure, regeneration and economic development, said: “Providing low carbon heat to the Queens Quay housing development, as well as the college and local businesses, really does put Clydebank at the forefront of renewable energy technology and it is fantastic to see the interest that is being generated by this exciting project.

The scheme looks set to deliver huge environmental benefits, as well as financial ones, far into the future. I am really looking forward to the completion of the system, and to see whether we can expand or replicate the idea elsewhere.”

Cutting through confusion

Concluding his series of articles, Graham Wright, chairman of the Heat Pump Association, discusses the problem of inaccurate field trials... and why a garden pond is unsuitable to support a water sourced heat pump.

It has been an encouraging year so far for the heat pump industry. Our consultant Graham Hazell was invited to speak at Westminster in February as part of the government’s inquiry into ‘Technologies for meeting Clean Growth emissions reduction targets’, and this was followed by the announcement in the Spring Statement that that gas boilers will be banned in new homes from 2025.

The future of heating in the UK will involve a number of technologies, some established and some that need development. There will be various claims made about the pros and cons of each but here I will try to clear up two more issues of contention regarding heat pumps.

Field trial inaccuracy We have acknowledged in the past that a major short-term shift to heat pumps would be impractical. Something we must strongly refute, however, is that heat pumps are a bad choice of heating system based on the idea that field trials have ‘proven’ them to be inefficient. The truth is field trials have been proven to be very unreliable and inconclusive, and poor field results aren’t restricted to just heat pumps. ALL heating systems’ efficiencies measured in the test cell are unlikely to be repeated and are likely to be significantly lower than those measured in-use. Results significantly poorer than laboratory tests have been

revealed for oil and gas fired boilers as well as significantly for biomass boilers.

Measurement of accuracy in field tests is particularly difficult since it is much easier and likely to be more accurate in the laboratory than out in the field. This is even more so if there is inadequate training and poor installation for the installation of metering as demonstrated by the government backed RHPP field trials.

Field trials have been most inconclusive as to the reasons for the figures calculated but proved they are NOT directly related to the ‘obvious’ things like manufacture/book performance figures, flow temperature, type of installation/building etc.

Ponds aren’t suitable Drawing my observations on the myths surrounding heat pumps to a close, a question we’re often asked is whether your

average garden pond is able to support a water sourced heat pump. Unfortunately for green-conscious lovers of aquatic life, the short answer is no – unless you are looking to heat something no bigger than a well-insulated dog kennel!

Any source needs to have sufficient heat capacity (in this case volume) to deliver the required amount of heat energy until the heat is replenished. A pond 4m in diameter and 0.5m deep is likely to hold just 37kWh of energy meaning it could supply a heat pump of 8kW for just over 4.5 hours full load. And this is assuming that the heat is replenished in the pond by the next time heat is required.

While there is still work to do to give the wider public a better idea of how heat pumps work and their benefits, I hope this series has gone some way to clear up some of the confusion in the industry surrounding heat pump technology. It’s easy to make all sorts of outlandish claims but undoubtedly the single biggest impact will be the view of the present (and future) governments and more importantly what action they take. In the meantime it is crucial that the heating industry as a whole continues to develop technology for a greener future and increase awareness with accurate information on the various technologies available. www.heatpumps.org.uk

Senior restructure marks Kensa’s 20th anniversary Management changes announced as manufacturer reaches milestone.

The Kensa Group has announced changes to its senior management team as it celebrates its 20th anniversary and targets further growth.

James Standley has been promoted to managing director of Kensa Heat Pumps, the UK’s only ground source heat pump manufacturer, whilst Dr Matthew Trewhella will step up to the same role for Kensa Contracting, the specialist in-house installation business.

Kensa Group CEO Simon Lomax said: “Having spent 20 years promoting the benefits of ground source heat pumps, it is encouraging that many stakeholders finally recognise their strategic importance.

Regulation is now replacing subsidy as the main market driver and the Kensa Group is remarkably well-placed to take advantage.

James and Matthew have been heavily involved in the creation of two exceptional businesses and their plans for the future will ensure Kensa continues to flourish.”

Alongside the management changes, Kensa has announced the launch of a

new business, Kensa Utilities, which will operate alongside a number of partners to fund, own and maintain heat pump assets. In addition, the group is developing alternative business models, including a ‘heat as a service’ offer, designed to reduce upfront capital costs.

Sustainability commitments Lomax added: “The emergence of heat storage products, dynamic electricity tariffs, smart controls, demand aggregation and battery storage will revolutionise the heat market and strengthen the appeal of our technology. Ground source heat pumps are far more suited to maximise the benefit of demand side response initiatives and benefit from far lower ownership costs. The challenge has been to reduce their upfront cost to mirror air source heat pump pricing and we can now deliver on that ambition. As a result, the market can benefit from a more efficient, reliable, durable and unobtrusive product.”

James Standley said: “From 1999 Kensa Heat Pumps has been influential in the

UK’s steady transition to a low carbon economy. The group’s structure is now poised to help the country fulfil its sustainability commitments and enter a new phase of clean energy generation.

I am proud to be at the helm of the manufacturing business, and look forward to our next chapter of growth as a group.”

Matthew Trewhella said: “I joined Kensa in the early stages of setting up the contracting business and it is been very satisfying seeing it grow from an idea to a fully-fledged business in its own right. I am immensely honoured to be named as managing director of Kensa Contracting and the management team and I am excited to be asked to take on the challenge of growing the business to the next level.”

E N V IR ON ME N T

Using our voice to reach Net Zero in HVAC Andrew Slater says the industry needs to exploit design potential and educate customers.

From identification in Vienna 1985 to net zero in the UK by 2050... climate change treaties, framework strategies and protests will span 65 years before we meet the greenhouse gases (GHG) target encouraged a few weeks ago by the Committee on Climate Change (CCC).

Regular reviews of targets and progress by the CCC have been made possible by both advances in scientific and technological capabilities and availability since the passing of the UK’s Climate Change Act in 1998. A greater than predicted 30% reduction in GHG over the last 10 years has largely been down to the increased use of renewables for power generation. Limited progress has been seen from the building sector even though the cost for renewable technologies have fallen, but why?

Socio-economic reasoning is the difficult unknown when predicting routes of progress. Even though everyone, in principle, has long-term considerations for their wider environment, most people live in a society and frame of mind of short-term gain. Unless you work within a very forward-thinking company and with forward-thinking clients, projects within the HVAC sector are regularly won and lost based on price. Lifestyles are kept based on wages and without a job the intention of trying to meet ‘environmentally friendly’ targets are in vain for an individual working on a professional front. Whilst some funding options are in place for capital expenditure on renewable technologies, they are clearly inadequate.

But then again, what chancellor is going to announce an extra pot of significant funding as an incentive when he has to stand the criticism for either borrowing or offsetting the cost to other sectors?

The intergovernmental Panel on Climate Change has indicated that electrifying heating methods are most likely to be used to generate the low carbon heating required throughout the domestic market.

This is due to the availability of technology in comparison to other combustible sources

such as hydrogen, along with the availability to start progression within the national grid. The immediate result has been shown with the Government announcing that no fossil fuel heating will be installed in new homes after 2025.

But is a collection of large ‘traditional heating’ manufacturers going to let this conversion take place within five and a half years, removing a large proportion of profits or risk other methods such as hydrogen where relatively little research has been conducted? I noticed a piece in The Guardian recently from the Home Builders Federation indicating that heat pumps required bigger radiators and didn’t work well in cold snaps. I think they need a little education in designing circuits and selecting equipment other than at 70°C!

Dedicated industry The CCC has identified that less than 5% of the energy used to heat both homes and other buildings currently originate from low carbon sources. It has also identified heat pumps and heat networks as the main technologies to provide environmentally progressive solutions to this key area of GHG contribution. They do indicate that for most home owners, especially, losses in

capital expenditure are recovered from lower bills and from other areas such as operating an electric car. But surely this is estimated on the proviso that all decisionmakers across each sector keep their moral codes when applying cost to demand?

Also recognised by the CCC is a national shortage in skills to apply a low carbon approach. Having worked with renewable products for around 18 years, I would say that the problem is more the involvement of people of no skill that follow anything with a funding package, again highlighting the short-term financial gain. Perhaps Government should take more interest in forming internal departments to regulate changes in domestic practices, especially when attempting to introduce change to a nation of historic gas consumers rather than allowing profit making consumer protection companies to provide ‘confidence’ to the people who find themselves out of pocket.

What can the HVAC industry do better?

Commercially, we just need to exploit the design potential that is put in front of us and educate our customers. Domestically, we need to shout about the technologies we have! The mainstream media is full of climate change material, at government level through to Greta Thunberg skipping school! But what they don’t have is our voice - the voice of a dedicated industry who can highlight our contribution and provide confidence in our new technology and approach.

Industry welcomes CCC's call to action

The heat pump industry has welcomed the Committee on Climate Change (CCC) report which says a net zero target for greenhouse gas emissions by 2050 is both achievable and affordable using existing technologies.

The Net Zero report highlights the need for swift implementation of a regulatory framework to achieve the decarbonisation of heat and recommends a range of policies, including support for low carbon heating and a nationwide training programme to upskill the existing workforce.

Graham Wright, chairman of the Heat Pump Association (HPA), said: “The HPA wholeheartedly supports the report’s recognition that urgent action is required to meet a net-zero target and welcomes the specific recommendations for decarbonising heat within the publication.

“Momentum is now gathering among the public acknowledging the need to change the way we heat our buildings and, as highlighted in the report, known technologies, such as heat pumps, offer a clear solution for this.

“Heat pumps offer an extensive opportunity to reduce the UK’s emissions, as well as helping to address other policy issues such as fuel poverty and air quality. The Future Homes standard, set to be introduced in 2025 and supported within this report, represents the ‘low-hanging fruit’ of heating in new builds, which, in addition to those properties off the gas grid, should be the immediate focus for the Government.”

Bean Beanland, chairman of the Ground Source Heat Pump Association, said: “The association is very pleased that the CCC recognises the contribution that heat pumps can make towards achieving net zero by 2050. Ground source heat pumps are a proven, efficient and low carbon technology that can deliver heating to households and businesses at the lowest operating cost. A heat pump deployed today is progressively lower

in carbon emissions over its lifecycle as the electricity grid is decarbonised further.

“The nocturnal temperature stability of the in-ground asset also provides for beneficial load shifting opportunities that other technologies cannot match. This allows owners of ground source to consider adding thermal storage to take advantage of agile electricity tariffs where, under the current generation mix, low cost overnight electricity broadly equates to the lowest carbon factor electricity.

“To accelerate heat pump deployment across the country, we want to work with Government and other parts of industry to improve and monitor standards to ensure the strongest possible consumer confidence and protection, and to provide high quality transition training for existing conventional heating sector technicians to both protect jobs and to meet the uplift in market demand.”

Phil Hurley, managing director of NIBE Energy Systems and recently appointed vice-chair of the HPA, said: “The changes required to meet this new target will be

significant but they are essential. As noted by the committee, we are now in a crucial period in the efforts to tackle climate change and the report published today calls for increased ambition. We welcome this and the recommendations within the publication.

“The UK has the ability to reduce emissions to net zero by 2050 using current technology and building on existing policy frameworks. However, to achieve the target we must ramp up activity and set to work immediately. Decarbonising our building stock is a particular challenge and one that must be urgently addressed. Policy thus far has failed to effectively drive take up of heat pumps, but to meet the target, a mass roll out is needed.

“The report highlights the need for Government intervention and NIBE Energy Systems looks forward to working with Government, the Committee on Climate Change and industry partners to develop a supportive policy framework which will enable a smooth and cost-effective transition to a net zero future.”

Tim Hopkinson, president of the Building Engineering Services Association (BESA), said: “This is a huge moment for our industry. All of these things are achievable and the building engineering sector is in the vanguard of zero carbon action. Additional policy levers will allow us to go further and faster, but we are already delivering low carbon heating solutions; energy efficiency and clean energy projects up and down the country.

“We embrace this vision and that of the climate change activists, who recently took to the streets to champion this issue.

However, we would stress to them that we are already on the right track. In 2017, overall emissions had fallen by 43% since 1990 and the building engineering sector has played a key part. We acknowledge the need to go further and faster and, if the government turns the CCC recommendations into policy, we can.”
