A Brave New Britain

What's New

Who expected a Brexit vote?

Theresa Geeson 01778 392046 theresag@warnersgroup.co.uk

Clearly, not many expected the UK to vote to leave the European Union. But, here it is. The question is how will it affect the air conditioning, refrigeration and heat pump industry? With EU legislation on refrigerants, for example, driving much of the change and new business for many of you, how will it affect these plans? Will the UK continue to adopt the environmental legislation once the country leaves the EU? Or, will we develop our own standards? What will happen with jobs in the sector? Will demand ease off as the markets settle into the new reality of a life outside the EU? There is only thing which is certain. The UK is facing a brave new future, our industry will have to learn to quickly adapt to the world in which it now finds itself.

CHEMOURS FIGHTS BACK AGAINST ‘BANKRUPTCY’ REPORT

Chemicals giant, Chemours, a spin-off from DuPont, issued a statement recently denying a damning research which alleged it is ‘a bankruptcy waiting to happen’. Citron Research, a Wall Street analysis firm, published a report on 2 June 2016 stating that it believes Chemours was ‘designed for bankruptcy’. The research firm alleges that the chemical company’s legal liabilities and debts are the big problems, which its former owners wanted to shed.

LAWSUITS AND LIABILITIES

The legal liabilities are from lawsuits being filed against the firm for environmental contamination in parts of the USA. The contamination allegations are because of the dumping of the chemical C8 (PFOA), more broadly known as ‘Teflon’, into the environment. Chemours could face big legal bills and liabilities if the allegations are true. The Citron Research report alleges Chemours is $4 billion in debt which is putting the refrigerant manufacturer under pressure with its finances. Chemours’ share price has plummeted from US$20.85 in July 2015 to US$8.45 in early June 2016.

CHEMOURS FIGHTS BACK

In its own statement. Chemours stated that “strongly refutes the report by Citron Research”. The company said that it has a plan in place to reduce its debt burden to “approximately three times in 2017”, and to improve its earnings compared to 2015 by $500 million. Since being spun off from DuPont, Chemours’ management team has been cutting costs and investing in refrigerant production initiatives to improve its profitability, amongst other investments. It aims to cut costs by a further $200 million in 2016.

Aster Maintenance Buys Coolheat Aster Maintenance, the Hampshire-based M&E Contractor, has bought the cold room and refrigeration specialists, Coolheat, the company announced today. Aster Maintenance completed the deal last week and it will mean that the contractor has expanded its offering into refrigeration, enhancing its existing heating, ventilation and air conditioning expertise. Mark Shadrake, Aster Maintenance managing director said: “It is our intention to initially operate the company as a subsidiary of Aster whilst gradually integrating the operations of both. This will be a positive step for both companies and will open up whole new set of customers for Aster and Coolheat”.

CMA GIVES BEIJER REF ALL CLEAR OVER HRP The Competition and Markets Authority (CMA) gave Beijer Ref the go-ahead to continue restructuring the air conditioning and refrigeration wholesaler HRP. Beijer Ref bought the struggling HRP outright in November 2015 and began a program to bring the company back to profitability. The CMA put Beijer Ref’s plans on hold in January amid concerns that buying HRP would be anticompetitive for the air conditioning and refrigeration market. In January, Beijer Ref UK & Ireland MD, John Billson, was confident that the CMA would clear them to continue getting HRP into shape and that the authority would find no reasons for concern. John commented on the CMA decision : “We were highly confident that the acquisition of HRP would not reduce competition and are satisfied that the CMA has recognised this. My team and I can now get on and develop the HRP, 3D and HRP OEM brands”. He continued: “I would like to take this opportunity to thank our suppliers, customers and employees for their understanding and support during this process.”

NEW APPRENTICESHIP PROGRAMME

STARTS THIS SEPTEMBER! News this month from the IOR programme of talks, tours and work to raise the profile of the UK RACHP industry

B

usinesses of all sizes should be thinking about taking on apprentices now. Not only is Government funding available that will cover two thirds of the training costs, but there is a completely new industryled Apprenticeship programme coming on board that is designed to ensure trainees have the skills to deal with both today’s and tomorrow’s industry needs.

With a strong emphasis on applying the fundamental principles underlying refrigeration, air conditioning and heat pump technologies, the new Apprenticeship programme will equip your business with core skills, knowledge and behaviours. Employers have worked together to set both a stringent national Standard for the apprentices and a new set of Assessment methods to make sure all apprentices, at all colleges reach the same level at the end of their three year programme.

WHAT’S CHANGED?

WHAT HASN’T CHANGED?

₀ There will be a single Apprenticeship structure called “Refrigeration, Air Conditioning and Heat Pump Engineering Technician”. It is no longer part of a mechanical or building services suite and there is no need for apprentices to choose between installation and commissioning, simple and complex systems or refrigeration and air conditioning practice.

₀ City & Guilds are still providing the assessments and certificates for the Apprenticeship.

₀ It is a single three year programme leading to a Level 3 Apprenticeship Certificate (equivalent to GCSE A levels). ₀ Employers will have a greater responsibility for ensuring their apprentices apply their learning at work and record their experiences.

₀ Apprentices will still have to attend colleges to learn, practice and take exams – at least 20% of their time must be spent in training. ₀ Apprentices will obtain an F Gas Certificate as part of their Apprenticeship. ₀ Qualifications at Level 2 and Level 3 will still be available to assess trainees’ progress towards their final Apprenticeship.

₀ At the end of the apprenticeship all candidates will be assessed externally by an independent panel of industry experts to make sure they all have achieved the same level regardless of which employer or college they attend. ₀ Apprenticeship funding is available to students of any age. ₀ More rigorous standards eg for qualifications of trainers are being put in place

Jane Gartshore Listed in

WOMEN IN ENGINEERING This well-respected co-owner of the consultancy and training firm, Cool Concerns, has been included on the Daily Telegraph’s ‘Top 50 Women in Engineering’ list.

T

he list is part of the National Women in Engineering Day campaign which recognises women making a difference in the world of engineering. Jane’s inclusion recognises the importance of air conditioning and refrigeration as a professional career choice in engineering. The Daily Telegraph and the Women’s Engineering Society compile the list from around 900 nominated female engineers. The list includes prominent women in engineering including Dame Ann Dowling OM DBE, President of the Royal Academy of Engineering and Technology, Dame Judith Hackitt DBE, Chair of EEF, the Manufacturer’s Organisation, and Naomi Climer, President of the Institute of Engineering and Technology. Jane Gartshore has a high profile within the refrigeration industry, in which she has served as President of the Institute of Refrigeration (IoR) from 2007 to 2010. She chaired the IoR’s Education and Training Committee, and is also on the British Refrigeration Association’s Council.

Leadership in Sustainability

Jane’s lead in sustainability issues throughout her career have made her a thought leader on subjects including energy efficiency, deploying natural refrigerants and reducing refrigerant leakage. Jane’s international work includes working with UNEP to bring about the phase-out of CFC in developing countries. Jane commented on her career in refrigeration and air conditioning:

Jane Gartshore with Steve Gill (President of the IoR) at the National Women in Engineering Day event

Jane Gartshore.indd 14

“Engineering offers so many opportunities to work all over the world in a huge range of sectors. It’s an awesome career! Every day is challenging and interesting.” “I chose to study engineering at university on the advice of my (male) physics tutor. It seemed more interesting than teaching and more attainable than being an astronaut. My entry into the refrigeration industry in 1977 was purely because I was offered a graduate trainee position by a compressor manufacturer. I initially worked on the design and development of commercial RAC equipment and then moved into technical sales, a global troubleshooting role.” “In 1991, with another engineer, I set up Cool Concerns to provide practical training and consultancy for the RACHP industry. We have trained thousands of engineers on topics ranging from the basics to the safe application of flammable refrigerants.” “I have worked all over the world and most of that work has been to do with the deployment of alternative refrigerants (in which the UK leads the world.” In the UK, as well as developing training programmes, I work with clients to help them comply with standards and regulations on various sustainability projects.” “None of this is achieved on my own. Engineering is very a team job and this is part of its attraction.” Other women in engineering on the list include Steph McGovern from BBC Breakfast, Nina Skorupska from Renewable Energy and Debbie Smith from the BRE. Follow updates about the National Women in Engineering Day on Twitter using #NWED2016 and help to raise the profile of awareness of the exciting career opportunities available to them in engineering and the air conditioning and refrigeration industry.

CHILLED BEAMS

AN ENERGY EFFICIENT AND FLEXIBLE ALTERNATIVE TO FAN COIL UNITS

Fan coil units (FCUs) have been providing air conditioning to thousands of buildings since the 1970s, but it could be time to consider an alternative that delivers both energy efficiency and flexibility – namely the chilled beam. Yan Evans, vice president of the UK Sales Unit at Fläkt Woods, explains more.

O

ne of the key drivers for air conditioning in recent years has been the need to create ‘comfort cooling’ in occupied buildings where the use of IT equipment has increased. This has come at a cost to both business and the environment.

The Carbon Trust has stated that air conditioning can increase a building’s energy costs and associated carbon emissions by up to 100 per cent, and it is estimated that cooling consumes up to 14 per cent of UK electricity. As the EU has set a target for a 20 per cent reduction in

Flakt Woods.indd 16

energy consumption by 2020, the focus on air conditioning efficiency is likely to increase.

No Noise, Less Expense

FCUs have, of course, become more energy efficient due to the legislatively driven introduction of electronically commutated (EC) motors, but chilled beams, which do not require a fan, are inherently more energy efficient and can offer savings of up to 40 per cent over traditional systems*. Chilled beams circulate air using the principles of natural heat convection and

their major advantage over more common forced-air systems is that they circulate air without the noise and expense of ductwork and air handlers. Typically mounted overhead, the beam is chilled by an external source such as recirculated water and cools the space below by acting as a heat sink for the naturally rising warm air of the space. Water temperatures in chilled beams are higher than in fan coil systems – typically 14°C flow compared to 6°C – which enables the chiller to perform more efficiently. Chiller energy savings for a chilled beam system compared to an FCU can be as much as 35 per cent.

More Chilled Beam Benefits

While energy performance will drive many decisions, there are other significant advantages to be gained from chilled beam systems. Initial installation costs are lower, as is ongoing maintenance. FCUs, for example, require wiring for the fan. The way in which FCUs operate also adds to their cost. The low water temperature required causes condensation on both coil and pipework, which leads to the need for anti-condensation protection. FCUs also normally need a filter to prevent the coil becoming clogged with dirt caused by the coil becoming wet. In contrast, a chilled beam system needs no condensation protection because the chilled water temperature is typically above a room’s dew point and, as the chilled beam coil is dry, there is no need for a filter. As well as considering the impact on

energy costs of air conditioning systems, specifiers and building owners often need to consider future-proofing. In many building projects – particularly office and retail spaces – the HVAC systems are designed and installed without knowledge of how the space is likely to be divided in the future, so flexibility can be a key consideration. Where there is the likelihood that a building will be restructured internally during the lifespan of its systems, with walls, occupancy levels and room functions changing, HVAC systems need to be flexible.

More Flexible Than You Might Believe

One misconception that still exists about chilled beam units is that they consist of a 3m rectangular beam that is largely immovable, which is not particularly helpful if the floorplan is likely to change. Today’s chilled beams are considerably more flexible, and systems like Fläkt Woods’ Wega II active chilled beam system deliver energy efficient cooling, heating and ventilation in a flexible format.

With Wega II, floor layouts can be changed without the need for moving or installing new beams, requiring only simple adjustment and reconfiguration of the FPC vanes and the variable position nozzles. Equally the Pi functionality, being pressure independent and making the Wega II suitable for many types of ductwork, is designed for change. It can be easily moved by disconnecting, reconnecting and resetting the values. The design also includes variable geometry nozzles, which offer an optimum choice of airflow settings. Nozzle change can be actuated to adjust ventilation flow rates automatically to occupancy levels, regardless of pressure changes in the ductwork system.

What’s the Demand for Chilled Beams?

It’s estimated that globally the chilled beam market is expected to grow at an estimated compound annual growth rate of 11.14 per cent between 2015 and 2020, driven by the increase in demand for energy saving in buildings and enhanced thermal comfort for occupants. And as new generations of chilled beam systems come to market, their ease of installation, potential for energy saving and long term flexibility represent an increasingly attractive alternative to FCUs for the specifier, designer and end user alike.

demand led CO2 control of fresh air supplies to each of the office floors. The aim was to reduce AHU fan power consumption and ventilation thermal loads, whilst meeting the fresh air requirements of the building occupants.

By changing the way the building controlled the internal air quality, by supplying fresh air in the office spaces based upon occupancy, significantly reduced energy consumption. The modulation of the AHU based on the air-quality sensor readings reduced the AHU fan motor load by 30% during the operational hours with additional savings on chilled water and LTHW demand on the cooling and heating systems.

Roof mounted central AHU’s provide supply and extract to the office spaces to meet the minimum fresh air requirements. The incoming fresh air is tempered and incorporates a thermal wheel for exhaust heat recovery. The new duct mounted air quality sensors on the connection to each office floor modulate a control damper to vary the supply air volume and meet the minimum fresh air requirement based upon the occupancy. The AHU’s were controlled on constant volume by the BEMS using TREND’s IQ3 system and 963 supervisor, and following the installation, this was changed to constant pressure with varying air volume.

The Challenge

Dashwood House (London) is a commercial office building, where the ventilation system controls were enhanced with CO2 sensors and motorised control dampers to provide

Acorn.indd 20

The Solution

The building now controls on internal air quality, supplying fresh air in the office spaces based upon occupancy and significantly reducing energy consumption. These changes have maintained the office environment, by varying the fresh air volume based on the air quality readings from the floors, ensuring the supply air meets the actual requirements. The reduction in supply air volume also reduces the AHU ventilation heating and cooling loads on the boiler and chiller plant, respectively. The modulation of the AHU based on the air-quality sensor readings reduced the AHU fan motor load by 30% during the operational hours with additional savings on chilled water and LTHW consumption on the cooling and heating coils. This enhancement of the ventilation system controls provided estimated fan energy savings of 100,000 kWh per annum.

“In our search for a partner to work with our client, Land Securities, NG Bailey were looking for a company that would deliver practical, real world projects that would reduce our clients’ energy consumption. They were also required to bring something innovative and useful to the table. With the Control Performance Reports and site policing visits, AIS BMS have done just that. They have understood our needs and collaborated strongly with our own energy team which have helped us achieve significant results. We have built strong relationships with the team at AIS BMS and they have worked well for us throughout this project. A key factor to all of the energy reduction projects is that the disruption to the normal operation of the site had to be absolutely minimal, meaning the tenants of the building could go about their normal business. Overall, the results of the project are very encouraging, and working with AIS BMS has been an excellent experience.” Chris Coath, Head of Energy, NG Bailey

ITS WEAKEST LINK G

raeme Rees, Marketing Director at Trend Control Systems explains why, in the battle to thwart the growing threat posed by hacking, it is vital to ensure that a Building Energy Management System (BEMS) is as secure as possible.

All businesses are potential targets for hackers, and IT security breaches are making the news headlines on an almost daily basis. If the experts are to be believed, this current level of activity is just the tip of the iceberg and to highlight the scale of the issue, in 2014 the USA based Centre for Strategic and International Studies claimed that hackers stole roughly 81.5 million records worldwide, while The World Economic Forum has estimated a $3tn cost to the global economy if the problem is not taken seriously. Although it tends to be the attacks made on companies such as Sony and Microsoft that grab the public’s attention, organisations of all types and sizes are vulnerable and the PricewaterhouseCoopers (PwC) 2014 Global Economic Crime Survey found that one in four of those questioned

MANAGING RISK SHOULD ALWAYS BE ABOUT WHAT YOU CAN DO, NOT WHAT YOU CAN’T.”

Trend.indd 22

Don’t let a BEMS become a gateway to hackers had been hacked. One of the reasons that this nefarious activity has become so widespread is that the chances of getting caught are close to zero. Prosecutions are disconcertingly rare and by the time the alarm is raised the culprit has usually covered their tracks to evade detection. Horror stories about what can happen as a result of such an event are in no short supply, however, the level and type of threats are constantly evolving. While some are carried out for financial gain, others are designed to cause as much disruption to business operations as possible.

For further information please call Trend Marketing on 01403 211888 or marketing@trendcontrols.com

Protecting Organisations

Managing risk should always be about what you can do, not what you can’t. Organisations have to be more aware than ever of how to protect themselves and although it is the IT network infrastructure that is the focus of attention in terms of preventing such attacks, a comprehensive evaluation of risk requires a meticulous approach to mapping all of an organisation’s IT related assets and processes – including a BEMS. Although a hacker might wish to cause disruption by, for example, shutting down plant, altering setpoints or turning lights off, it is far more likely that any security based vulnerability in a BEMS would be used as a gateway or point of access to obtain confidential data. Preventing the latter should be a priority for every organisation. There are a number of UK and European laws that govern corporate liability for data breaches, and fines can be as high as £500,000. This is in addition to the cost in terms of operational downtime and business continuity, while not forgetting reputational damage.

Security Best Practice

Ensuring that a BEMS does not become a weak link in the security chain means being aware of, and applying, best practice. As well restricting physical access to the BEMS, making sure that it is not directly accessible from the Internet is a prerequisite. Similarly, only designated personnel should be able to use it and organisations should adopt a strict username, password and PIN policy. We are always told that it is wise to

27/06/2016 14:36

C O N T R O L S

regularly change our passwords and make them as strong as possible and this is something that applies equally to a BEMS. Security must be designed into the operation of the BEMS from the outset – it must never be considered an optional extra. This technology is not ‘fit and forget’, so all relevant equipment should have the latest software and firmware versions applied and all PCs that are connected over the network should run virus protection software with up-to-date virus definitions as a matter of course. It is advisable to isolate the BEMS from the corporate IT network infrastructure through the use of a virtual local area network (VLAN). This allows devices to appear as if they are not actually connected to the same cabling, even though they may be physically located on the corporate network. For additional security, a virtual private network (VPN) should be configured to prevent unauthorised access.

Employee Awareness

Security awareness must also form a part of any BEMS related training for employees and this should be considered as a priority to building effective prevention, detection and response. It should also be remembered that effective processes are entirely dependent upon implementation of policy – therefore strict adherence is required to mitigate the possibility of a security breach. Furthermore, the most effective preventative strategy can only be achieved through working with an expert BEMS provider. This ensures that each stage of the installation and maintenance process meets pre-defined standards. Although it is incumbent upon manufacturers to issue regular firmware and software updates, their availability should be immediately communicated to systems integrators, which should then carry out the necessary work. Finally, like most other aspects of successful BEMS operation, its security should be reviewed and tested on a regular basis. Assessing performance to determine its strengths and weaknesses is a key platform of organisational preparedness – something that no organisation can afford to ignore.

TIME TO STEP I A-Gas Managing Director John Ormerod says that progress is being made towards creating a low GWP landscape but more work still has to be done to achieve the underlying F-Gas goal

W

Getting into a trap

e are more than half way through the year and the time has arrived for the industry to increase its focus on the rapidly approaching F-Gas bans and refrigerant quota reductions. Most in the industry – manufacturers, contractors, suppliers and engineers – are aware that change is on the way and that it will have an effect on how we all operate on a day-to-day basis.

The time has arrived for the industry to up its game. Through the new quota system, as a supplier, A-Gas, like many others, are now subject to caps on the amount of refrigerant that we can place on the market. 2016 is the first step down year and there is a seven per cent reduction (on a CO2 equivalent basis) in the amount of refrigerant we can place on the market.

The Turning Point for Refrigerants

Many have yet to understand the full effects that the quota system will have on the industry. Contractors and engineers are continuing to get on with the job with low GWP refrigerants in the back of their minds. It is fair to say that a sizeable proportion of end users are not yet rising to the low GWP challenge. All industry observers say that whatever happens over the coming

AGAS.indd 24

John Ormerod

months and years, 2018 will be a turning point. The large reduction in the HFC quota will almost certainly have an impact on the cost of higher GWP refrigerants like R404A with prices likely to go one way and that is up. Some commentators are suggesting that this is overstating the case with supply problems and price increases being eased by the availability of refrigerants from stockpiles accumulated before the quota system started. I would suggest that planning ahead is a more sensible approach than hoping things will be okay. Ignoring the prospect of price rises is not a risk worth taking if you are an equipment supplier or an end user.

Most contractors, manufacturers and consultants consider themselves ready for the move towards low GWP refrigerants but that the problem area lies with the customer. This is where we must rise to the challenge. It is up to all of us in the industry, where we can, to remind end users of the trap they could be setting for themselves by not getting ready for what’s down the road. Low GWP refrigerants won’t be going away. They cannot be brushed to the back of our minds. Don’t get ensnared by debates on price rises, prepare for the future and ensure you are ready for what it may bring. It is time for all of us to spread the message about the benefits of low GWP refrigerants. Mildly flammable HFO blends are opening a new window for end users and equipment suppliers. These HFOs blends do offer a practical alternative to higher GWP refrigerants. The Solstice L40X (R455A) refrigerant from Honeywell is an ultra low GWP R404A replacement which will soon be commercially available. This hybrid mixture contains R32 and CO2 and closely matches the capacity of R404A with the same or better efficiency.

P IT UP A GEAR A question of flammability

R32 is already making its mark in air conditioning especially for split systems. Under F-Gas small split systems containing high GWP gases (above 750) will be banned from 2025. R32 is a single component, zero ODP gas with a GWP of 675, significantly less than R410A, which has a GWP of more than 2000. Air conditioning manufacturers are working with R32 and equipment running on the gas is already available. Other legislation is also providing fuel for the low GWP campaign. Originally the European standard EN378 did not make a distinction between mildly flammable refrigerants like R32 and refrigerants

AGAS.indd 25

with higher flammability such as Propane and Propylene. This regulation which sets out the charge limits for mildly flammable refrigerants will soon provide new risk management methods for these alternatives. There is no doubt that the industry is changing but needs to step up a gear. Some end users are even suggesting that those suppliers who are dragging their heels on low GWP equipment could find themselves out in the cold. The industry as a whole is now under pressure as we move towards a low GWP landscape. www.agas.com

DEVELOPING INNOVATIVE S CO2 (R-744) and supporting technologies for the retail refrigeration sector

F

-Gas II regulation is driving the continual development and delivery of new refrigerant solutions for air conditioning and refrigeration systems. With pressures being made on the amount of CO2 Eq Tonnes of HFC refrigerants allowed to be placed on the market (also known as Quota), companies are now under increasing pressure to adopt refrigerant solutions that have less of a detrimental effect on the environment. Over recent years, CO2 (R-744) has

been making its mark across commercial and industrial refrigeration systems throughout Europe and demand for this product is set to increase. With its excellent cooling capability, low toxicity and non-flammable (A1 category) status, CO2 has some excellent environmental benefits such as a Global Warming Potential (GWP) value of just one and zero Ozone Depleting Potential (ODP). Regularly used in retail refrigeration, CO2 is also finding use across industrial applications such as refrigerated storage rooms and transport refrigeration, as has been seen in recent press. It can be used across a number of system technologies, including transcritical, subcritical, cascade and direct expansion/secondary fluid units. Probably due to its environmental benefits, CO2 is sometimes referred to as a ‘natural’ refrigerant. The jury is out as to whether this is technically true given the fact that there is a level of chemical transformation required in the creation of this product. However, regardless of this, the product has some really strong benefits which can help users to reduce their carbon footprint. Climalife believe CO2 popularity will grow and help the market deal with pressures on HFC refrigerant quota and F-Gas regulation.

Climalife.indd 26

Safety precautions when handling Lubricant innovation for high pressure CO2 CO2 (R-744) compressors

It is important to remember that CO2 is a high pressure gas (57.3 bar at 20°C) therefore it is essential (as with all refrigerants) that it’s handled with care. Users should ensure they have received specific high pressure and CO2 training before handling the product, wear suitable protective clothing, ensure the room is well ventilated with a CO2 detector and use specific equipment such as high pressure hoses and manifolds. Companies such as Climalife (IDS Refrigeration) can offer useful customer guidance on handling high pressure cylinders.

Climalife Managing Director Allan Harper said: “Climalife continually strive to innovate and excite the refrigeration and air conditioning market with new products and support tools. The Mooviz product has done just this. It’s a great product that sets to ease the life of the refrigeration contractor who traditionally may have had to transport heavy CO2 units and found them tricky to offload. The Mooviz product is here to minimise this effort and improve manoeuvrability whilst supporting the industry to meet the requirements of the F-Gas regulation and to lower its carbon footprint.”

Operations using CO2 face three technological challenges. The pressures involved in facilities using subcritical and transcritical CO2 systems, the high solubility of CO2 in lubricants that can potentially lead to a drop in viscosity and the solvent effect of CO2 that can reduce the thickness of the lubricating film on moving parts. New solutions however, are also coming to market to address these challenges. Exxon Mobil, for example, has developed a new polyolester (POE) oil for miscible CO2 systems. They promise excellent low-temperature fluidity and in-service viscosity control. Plus, with this growing demand for refrigerants such as CO2, Exxon Mobil’s Andrea Jacobson (Industrial Marketing Manager for Europe, Africa and the Middle East) claims: “Our new synthetic lubricant for refrigeration compressors will meet this growing need while also adding a range of equipment protecting qualities and, according to trials, potentially contributing towards enhanced energy efficiency.” More details on these trials can be viewed on the Climalife Group website.

Lightening the CO2 load

In recognition of changing demands, Climalife has launched its innovative new packaging for CO2 ; the “Mooviz” cylinder. Particularly useful when delivering to smaller convenience-type stores, where offloading space can be limited, the new Mooviz cylinder from Climalife is smaller than traditional units, lightweight and has wheels, helping to reduce heavy handling and the overall amount of effort engineers are required to use when delivering this product. More information is available from Climalife UK.

REFRIGERANT:

JOIN THE M Here, Martin Passingham, Product Manager for DX at Daikin UK discusses the opportunities that moving to R32 refrigerant presents for installers and the wider air-conditioning sector.

T

Refrigerant Future Proofing

he introduction of the European F-Gas regulation in 2015 set the path for the gradual phasing out of refrigerant gases with a high global warming potential (GWP). Encouraging the air conditioning sector to move towards more environmentally friendly gases, with lower GWPs, gases such as R404a and R410a are starting to be phased out. As such, leading manufacturers have been seeking an environmentally friendly refrigerant with a lower GWP. An ideal solution for refrigerantbased air conditioning systems is R32. With a significantly lower GWP of 675 compared to R410a’s 2088, utilising R32 gas is an energy efficient and cost effective method of future proofing an air conditioning system. Its acceptance by the industry has recently been demonstrated by leading air conditioning and refrigeration supplier, Climate Center’s announcement that it will now be stocking R32 air conditioning systems across all its branches.

F-Gas Awareness

A live poll, recently conducted during the Daikin UK D1 Partner Conference, gauged the opinion of over 150 of the largest HVAC contactors on a host of industry issues, including alterations to the F-Gas regulations. Although more than twothirds of those polled were fully aware of these alterations, the result did show that more could be done by regulators to keep contractors fully informed. The fact that nearly one third of the UK’s most elite air-conditioning installers and contactors

Daikin.indd 28

were not aware of these changes, considering the new F-Gas regulations came into force on 1st January 2015, is a clear demonstration of the level of communication still required regarding the legislation’s impact. Despite this, encouragingly, the survey also found that there is an aptitude amongst a majority of installers to adapt and embrace the new refrigerant, with nearly 80% of those surveyed ‘happy’ or ‘keen’ to use R32 refrigerant to comply with the legislation. By getting ahead of the curve, those first to try the new products will be able to offer their customers a future proof system, compliant with the upcoming high GWP gas phase out and restrictions. Not only does this benefit the customer, but it also presents several business benefits.

With the F-gas phase down continuing for at least 14 more years, this legislation will be the key driver of change for the air conditioning sector. Those who embrace new environmentally friendly and energy efficient refrigerants early, rather than waiting for restrictions and limitations to force them to change, will have gained vital experience, and therefore, a competitive edge over their counterparts. In addition, for those offering the future proof systems as part of their portfolio now, it is a clear demonstration of their company’s commitment to innovation, continued development and reducing the environmental impact of the sector. Installed with a very similar process to R410a-based systems, a majority of the tools required for a R32 system can be shared across either installation process. This means there is little investment needed to begin installing the new systems. For those seeking additional knowledge and training to ensure confidence when installing the new refrigerant-based systems, training courses are available from Daikin UK’s leading training centres across the country.

E MISSION Removing Refrigerant Glide

An added benefit of using R32 is that as a single component refrigerant, removing the potential for the refrigerant to suffer from glide or component boil-off, and allows for easier system recharging and recycling.

Daikin.indd 29

Pioneering the benefits of R32, Daikin UK recently launched to the UK market the Daikin Bluevolution R32 air conditioning range and confirmed its use of R32 in all DX equipment – including, in the future, VRV. Following the initial launch of the Bluevolution range in Pilsen for traditional split units, the range has now been expanded to include the Daikin Emura and Sky Air products. Presenting only benefits to the end-user, the environmentally efficient system has seasonal efficiency of up to A+++. This, along with additional energy saving features, such as the intelligent eye and timer functionality, means that the Bluevolution range is extremely energy efficient. Furthermore, the new iTab controller provides total control over the unit; allowing the temperature, flow rate and operation mode to be operated from a smart device, anytime and anywhere with Internet access. The journey toward lower GWP refrigerants officially began at the beginning of 2015, however, now is the time to take advantage and begin installing R32-based systems. Offering a significantly lower environmental impact, higher energy efficiencies and a familiar installation process, the benefits of systems using R32, such as Bluevolution, are clear.

WOMEN in the

ACR industry H A Y L E Y

Where did you study and what course/ diploma/degree did you gain? I studied at Crownship, a training company in Hull. I gained my F-Gas certification, and my NVQ level 1 and 2 in refrigeration and air conditioning. I also spent two weeks on the road afterwards my training getting practical experience. I spent this time with Service Engineer, Carley Gorman when she was with WR. Carley was a finalist in the Trainee of the year awards and was an ideal choice. I helped her with service and maintenance repairs for supermarket refrigeration customers.

B I L L S O N

This month’s interviewee for the Women in ACR series is Hayley Billson. Hayley, daughter of John Billson, Managing Director of Beijer Ref UK and Ireland, is the sales manager for refrigeration and air conditioning wholesaler, Dean & Wood a member company of Beijer Ref, working at their Birmingham branch.

This time was short in relation to my two year training program, but very valuable. It taught me a lot about the realities of life as a service engineer. As a result, I can now empathise with customers, knowing what they do day in and day out. I was also keen to get involved with the industry in other ways so, I joined the IOR, in Newcastle and the IOR, London dinner commitees. This enabled me to get involved with non wholesaler topics.

What attracted you to the industry? My Dad! He has been in the industry for 40 years, so I have grown up with refrigeration and air conditioning. When I was two years old, my Dad practised his acetate overhead projector presentations to me and my sister Clair, who like me, has recently joined the industry.

What do you specialise in now? I started my ACR career in Marketing and then moved into ACR Wholesaler Sales. I was Sales Trainee in Leeds area, followed by a two year stint in Newcastle as Sales Engineer. I then managed the Birmingham branch of Dean & Wood. Continued on page 32

along the way. In contrast to the cut and thrust, it is a sociable industry, which adds fun to the pressure.

What would you say to other women who are considering coming into the ACR industry? Do not be intimidated about the industry being male dominated. Everyone I have met during my seven years in the industry has been kind and welcoming. Not once have I felt that my gender was ever an issue.

Where do you see your career developing? I get inspiration from my Dad and have always chased his footsteps. I am ambitious enough to believe I could part fill them one day. That said he has big boots to fill for such a small guy!

I LOVE NOTHING MORE THAN MEETING PEOPLE. WHETHER THEY ARE CUSTOMERS, SUPPLIERS OR COLLEAGUES ” ,

What are the challenges of this industry? It was clear to me that it was the sales part of the job that enthused me the most. I get a real buzz from supporting my customers with pre and after sales and this is what I chose to specialise in.

What do you know now about the industry which you wished you had known before? Every day is a school day and there are no limits to the learning. I have also, recently, come to realise that you can continue to have a career in the industry as well as being a new mum. (At the time of writing, Hayley and her partner, Greg, are expecting their second child in July).

What excites or interests you about the industry and your part in it now? In my role, I love nothing more than meeting people. Whether they are customers, suppliers or colleagues. I have met some great characters and have made some true friends

Women in ACR.indd 32

‘Refrigerant legislation’. The enormous, continuous change with refrigerant legislation is a challenge for most people within the industry. No sooner do I get used to the most recent refrigerants, the legislations change and with it new products are developed. And, so, new refrigerants and new equipment to suit them is not only industry challenging, butis my most challenging sell at the moment. Well gone are the days when people simply buy a branded product from a Wholesaler Mate.

What are the benefits of being in your role? I like to think the main benefit is to my customers, the extra value I can give them to take cost out of their supply chain by offering solutions to headaches. For me personally, being a people person I get to meet new people on a daily basis.

THE IMPORTANCE OF INSULATED PIPE BRACKETS Here, Anthony Barnett, Technical Marketing Manager at Armacell, looks at why insulating brackets correctly in a heating and cooling system is just as important as the pipework itself.

T

he thickness of the insulation material used for pipes and fittings must obviously meet minimum regulatory requirements. However, in some situations there may be other factors to consider, for example, if there is an increased risk of legionella because the hot and cold pipes are laid in the same duct or water does not circulate regularly, it may be necessary to use what is known as 100% insulation. This is where the thickness of the insulation roughly corresponds to the outer pipe diameter. That would mean if the pipe diameter is 22mm, the 100% insulation thickness would also be 22mm. On hot drinking water pipes this not only prevents legionella, but protects the pipes against unnecessary energy losses. For cold water pipes, this approach protects against freezing in cold weather as well as providing protection against unwanted temperature rises. However, in some systems the pipe supports are often overlooked, which can result in significant energy loss. A thermal heat flow calculation for a 60°C hot water pipe in continual use showed 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 on total energy costs of running a system especially where multiple supports are used. The only effective way of achieving a reliable connection between the clamps and an elastomeric insulation is encasing the PUR/PIR clamp with insulation as shown in Figure 2.

Closed cell insulation

Aside from using 100% insulation and adequate pipe support brackets, the type of insulation material used has a bearing on overall system performance. One of Continued on Page 36

the most effective materials is closed-cell insulation, which has a high resistance to water vapour diffusion, making it ideal for use on cold systems where condensation is likely to occur. By preventing moisture ingress and providing no ready food source, closed cell insulation discourages the growth of microbes, which makes it particularly suitable for using in sectors such as food and beverage where hygiene is important. Ranges such as our AF/Armaflex Class O closed cell insulation have an additional anti-microbial protection built in, giving active protection against microbial growth. Conversely, open-cell materials, even when used as a 100% insulation and whether specified with or without a vapour barrier, won’t sufficiently prevent moisture ingress as a result of diffusion. This means that there is a danger of water vapour saturating the insulation material. As the material becomes damp, its thermal conductivity increases and insulation properties deteriorate, causing greater energy losses, and a greater likelihood of inefficiency, condensation and proliferation of mould and bacteria.

IN CERTAIN APPLICATIONS, 100% INSULATION CAN BE A HIGHLY EFFECTIVE METHOD OF ENSURING THE HEALTH OF THE BUILDING OCCUPANTS”

Conclusion

In certain applications, 100% insulation can be a highly effective method of ensuring the health of the building occupants as well as maintaining efficiency of the system. However, not only the pipework but the brackets should be properly insulated and, preferably, with a closed cell material. Bear in mind, too, that pre-lined pipe clamps may not be adequate - a complete insulation system approach is often best. This is where the insulation material and insulated pipe supports are sourced from the same supplier, which offers greater compatibility in terms of condensation control, fire behaviour, energy saving and ease of installation.

SUPERMARKETS:

HOW TO SLASH YOUR HVACR BILLS Supermarkets are intensive consumers of electricity – yet few are taking advantage of modern techniques for achieving dramatic savings. Barry Lea, Chairman of Advanced Engineering, explains all…

E

lectricity consumption by supermarkets in the US and France is estimated to account for 4% of the country’s total annual electricity use. On a national scale that’s a staggering amount of electricity, with supermarket managers under constant pressure to reduce their store’s energy demands and operational costs. One key to achieving this has emerged via a landmark study conducted by US experts ASHRAE (the American Society of Heating, Refrigeration and AirConditioning Engineers). The study provides concrete empirical evidence – for the very first time – that substantial reductions in energy consumption and significant cuts to electricity bills can be achieved simply by cleaning a HVACR system.

Modern cleaning methods are key

At Advanced Engineering, we have long argued that large HVACR efficiency savings can be made by adopting effective, regular maintenance regimes. Achieving those gains, though, depends on using modern cleaning chemicals specifically formulated to thoroughly deep clean a HVACR system. As an example, one of the new generation of smart, heavy duty cleaners – SuperClean – uses a powerful chemical foaming action to make light work of removing even the most stubborn scum and baked-on dirt, as well as inhibiting future oxidation.

Supermarkets: breaking down The heavy duty SuperClean and its sister product EnviroCoil – formulated the problem for more regular maintenance routines When we separate out the individual – are both designed to clean outdoor components of a typical supermarket’s condensers, but the indoor shop floor energy bill, it’s clear that one single cabinets also need to be regularly cleaned element stands head and shoulders above to significantly reduce their running costs. the others.

Results

The ASHRAE study

The 34-storey building in NYC has 1.2 million square foot of floor space which has to be cooled from 6am to 6pm using four large 30-year-old air handlers:

and in stockrooms) accounts for the largest slice in the supermarket energy usage pie by a country mile: typically 4555% of the total electricity used. It’s clear, therefore, that any attempt to reduce electricity costs by supermarket and facilities managers must begin by tackling the energy demands made by refrigeration systems.

Introducing the solution

To see how this works we must look at the hard facts of the ASHRAE study. In the analysis, the owners of a building at 1500 Broadway on Times Square in New York City wanted to know exactly what impact HVAC cleaning had on the energy efficiency of their air con systems. To do so they measured energy demand from the system for a week before cleaning and then again for a week after cleaning (concurring with ASHRAE Guideline 142002 on how to accurately measure HVAC energy savings). To ensure the study was reliable and independent, the building owners hired a certified and independent testing, adjusting and balancing (TAB) company to test and calibrate their data collection methods and instrumentation during the trial.

Advanced Engineering.indd 39

1. SF-6: 250 tons, 880 kW 2. SF-7: 123 tons, 433 kW 3. SF-8: 121 tons; 425 kW 4. SF-9: 81 tons; 285 kW After testing during the first control week, SF-8 and SF-9 were taken offline for two days to perform a modern deep clean on both air conditioners. The two systems were then put back into service and tested in exactly the same manner for a further week afterwards. In all, HVAC inspectors and TAB contractors continuously measured 54 different data points from the two air con systems for a week before and a week after cleaning, including: ₀ ₀ ₀ ₀ ₀ ₀ ₀ ₀

Coil differential pressure Air and water temperatures Condensate temperature Supply air velocities Outside air temperatures Humidity Volumetric flow rates Voltage and amps

The ASHRAE study found that cleaning each system decreased coil differential pressures by 14%, which produced a corresponding increase in the flow rate and overall cooling capacity of the system by the same amount. After cleaning, the smallest air conditioning unit of the four – SF-9 – started punching well above its weight, adding an extra 19-22 tons of cooling capacity (an additional 67-77 kW), increasing its overall capacity by a massive 25%. The thermal efficiency of the cooling coils in the cleaned systems increased by 25%, and condensate water temperature dropped from 3-4°C before cleaning to 1-3°C after. The inspectors estimated that 100 tons (352 kW) of cooling capacity would be added to the building once all four air handlers had been cleaned and restored in this manner.

Conclusion

Based on year-on-year HVAC building costs, ASHRAE estimated that cleaning one of the air handlers resulted in efficiency improvements that will lead to energy savings of up to $40,000 each year. These kinds of savings make dramatic reading, and it’s important to point out that if these regular services also included cleaning evaporators in supermarket cabinets, costs for a supermarket’s annual energy bill would be slashed even further. This is clear statistical evidence that very significant efficiency gains and substantial reductions in energy consumption can be made simply by cleaning and maintaining the air conditioning condenser on a routine basis. More than ever, supermarket managers and operational staff must appreciate the importance of paying more attention to the state, cleanliness and efficiency of their store’s ACR systems. www.advancedengineering.co.uk or speak to an advisor on +44 (0) 1256 460 300.

EFFICIENCY UPGRADES FOR COMPRESSORS SYSTEMS & CHILLERS ThermOzone recently returned to the site of a prior project in Lombard Street, London.

I

n 2008, they upgraded four Carrier chillers, retrofitting the original piston compressors to screw compressors. And, they removed R22 in favour of direct replacement R422D, and updating the controls.

That upgrade achieved ~35% energy savings, and has provided so far 8 years reliable life extension to chillers originally installed in 1988. The latest upgrade has improved efficiency by a further 33% by retrofitting to Inverters and R134a.

Inverter technology

Partial load control of refrigeration compressors, requires reducing effective capacity by making some of the machine inactive - in a screw a slide valve is used to reduce effective volume, in piston compressors banks of cylinders are bypassed. However, as the compressor unloads, its efficiency reduces markedly. Piston compressors on higher temperature applications are anyway very inefficient compared with the equivalent capacity screw compressor, and this accounted for the 35% achieved in 2008 when we converted to Screw compressors. More recently effective speed control of larger, high torque motors driving screw compressors has become an everyday reality. The key advantage is the slide valve can be held at 100% swept volume, with load variation achieved by simply varying operating speed. Applying an Inverter to a screw compressor can improve operating

R134a offers some key advantages for these chillers, with one notable disadvantage … ₀ R 134a is ~8% more energy efficient than R407C across the typical load range ₀ R134a operates at a substantially lower pressures, this is a particular advantage for older equipment because older vessels are placed under less stress. ₀ R134a is the lowest HFC for GWP CO2 tonnes rating, and established HFO refrigerants and blends are already commercially available ₀ The key disadvantage for R134a is its lower cooling capacity at the compressor ~30%, and to a lesser extend the evaporator ~ 10%.

MORE RECENTLY EFFECTIVE SPEED CONTROL OF LARGER, HIGH TORQUE MOTORS DRIVING SCREW COMPRESSORS HAS BECOME AN EVERYDAY REALITY.” Thermocom.indd 40

efficiency between 15 - 25%, according to the local conditions and load demand.

R134a -v- R22 / R407C

Most older water chillers still operate upon R407C as the direct derivative from R22, and upon equipment originally designed for R22 refrigerant.

Inverters can overspeed

Returning to the choice to use an inverter, when we apply this in conjunction with R134a upon a screw compressor we are no longer restricted to a 50 hz upper speed limit, indeed compressors we assign can be run to 70 hz, allowing us to re-achieve ~95% of the original cooling capacity upon R407C.

Evaporator limitation

Most cooling system capacities are limited by the choice of compressor, with ~5% spare capacity in the evaporator. negating most of the effective capacity loss, e.g. the same as the compressor.

Slower Screw compressor bonus

Since first applying Inverter screw compressors in 2013, we have observed at slower speeds screw compressor efficiency improves relative to full speed efficiency by up to 10% at minimum speed (typically 30hz). We have deduced that at slower speeds the sealing oil layer within the compressor has more time to establish so rotor tip blow by is reduced.

PAYBACK FOR THESE PROJECTS IS TYPICALLY 2-3 YEARS, AND HAS BEEN RECOGNISED NATIONALLY BY THE CARBON TRUST AS AN EFFECTIVE MEANS TO IMPROVE EQUIPMENT EFFICIENCY.�

In practice retrofitting a water chiller with screw compressors is showing measurable improvements of ~27-33% against data model predictions of ~20-25%. For most UK systems the ambient conditions experienced mean many chillers can attain lower load efficiency improvements above 20% for most of the year, with just a few weeks of day time running where the efficiency reduces. Payback for these projects is typically 2-3 years, and has been recognised Nationally by the Carbon Trust as an effective means to improve equipment efficiency. Some

buildings we have worked in have achieved overall rating improvements of 2 levels, e.g. G to E, or F to D. When this is balanced against prior improvements of ~35% the overall efficiency reduction from Piston with R22 / R407C (or equivalent), final overall improvement can be ~55-60%. At one site we have audited results showing low load improvements with R134a and Inverters of 72%, with Summer time improvements of 55%. Any savings that can be applied to the compressor can achieve substantial improvements for the clients. Call ThermOzone on 0118 918 1400 or sales@thermagroup.com

COMPLIANCE AND T by Alan Jackson and James Bailey from BJA Refrigeration Consultants.

www.bjacool.co.uk

The F-gas regulations are at the forefront of refrigeration compliance measures and are generally understood by the industry.

H

owever, there are many other areas of compliance that must be adhered to in the design, construction, servicing and management of refrigeration systems, and your customers expect compliance through all the services you deliver. This article provides a sample of areas of compliance that may affect you.

BS EN-378

Ensuring compliance in equipment selection is not just about reliability and efficiency. It relies on you designing and documenting systems that mitigate risks to ensure your customer has a safe and reliable system. Considerations should include: ₀ Ensuring your customer is aware of all requirements associated with construction – selection of materials, time-scales, pressure testing etc. ₀ Ensuring compliance during installation – mitigating risks, safe methods of

working and ensuring all site operatives and site visitors have a valid CSCS skill card is essential ₀ Ensuring compliance during the life cycle of a system is paramount– you must be able to prove traceability, technician qualifications & training, planned preventative maintenance, logging and recording of refrigerant use.

The Pressure Equipment Directive The Pressure Equipment Directive sets out the standards for the design and build of pressure equipment. It is your responsibility to: ₀ Identify the type of pressure equipment, fluid state, fluid group, selection of the appropriate

classification chart, determining the maximum allowable pressure & defining dimension, and establishing the PED hazard category. ₀ Ensure that PRVs are installed in appropriate locations. ₀ Ensure PRVs are tagged and recorded with system details – the date of installation is necessary to ensure that they are changed out at regulatory compliant intervals.

The Pressure Systems Safety Regulations 2000 (PSSR)

PSSR requires pressure systems to be inspected in accordance with a Written Scheme of Examination. They apply to owners and users of relevant fluids and gases under pressure which becomes a gas when released to the atmosphere. There is a legal requirement for thorough examination of pressure vessels and receivers that contain steam, compressed air and refrigerants. Any pressure vessel containing compressed gas over 250 bar / litres capacity requires inspection. Specific to the RAC industry, owner / users of refrigeration plant containing pressure vessels, with a capacity of over 25 kilowatts require a written scheme of examination and inspection. It is yours and your customer’s responsibility to ensure that

D THE END USER ₀ Cooperate and coordinate your work with other trades and professionals ₀ Have the right information about the risks and how they are being managed ₀ Communicate information effectively to those who need to know ₀ Consult and engage with workers about the risks and how they are being managed ₀ Ensure that your customer is aware of his responsibilities and obligations examinations are undertaken at the correct intervals.

CE marking

The letters CE appear on any OEM product. It identifies that a manufacturer has checked their products meet EU safety, health and environmental requirements. To ensure compliance for your customer, it is recommended that you confirm that the CE marking is on plant, coolers and specifically for the retail sector, display cases.

The (Construction Design and Management) Regulations 2015

It is your responsibility to ensure that you understand the requirements of the Construction (Design and Management) Regulations 2015 (CDM 2015), its high level purpose to ensure that you: ₀ Plan work so any risks involved are managed from start to finish ₀ Have the right people for the right job at the right time

BS 7671 (Wiring regulations)

British Standard BS 7671 “Requirements for Electrical Installations. IET Wiring Regulations.”, is the national standard in the United Kingdom for electrical installation. The 17th edition and amendments there after became effective for all installations designed after 1st July 2008. It is your responsibility to ensure that any that your electrical technicians comply with this regulation.

EU Waste Framework Directive (WFD) The EU Waste Framework Directive became a legislative requirement on the 12th December 2008. Applicable to ensure that you and your customers remain compliant include:

₀ The management of hazardous waste – this is waste that contains properties which if mismanaged have the potential to cause harm to the environment and human health. As a result, strict controls apply from the point of

its production, to its movement, management, and recovery or disposal. You and your customer are responsible for the management and traceability of this waste. ₀ The management of electrical and electronic equipment - Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances in electrical and electronic equipment (RoHS) directives aim to reduce the quantity of waste from electrical and electronic and increase its reuse, recovery and recycling. You and your customer are responsible for the management and traceability of this waste.

M44 – Air conditioning inspections

Properties in England and Wales with air-conditioning systems over 12kW are required to have an independent inspection of their units. If you, or your customer have air-conditioning equipment, you must have an inspection carried out at least every five years – keeping a record to ensure compliance for you and your customer is necessary.

Summary

There is much to cross reference between refrigeration compliance requirements, and when considering them a holistic manner it will become evident of the level of harmonisation that can be achieved to ensure that you and your customers remain compliant.

ack in 1888 Swedish inventor Johan Petter Johansson patented the very first adjustable spanner, since then Bahco has gone on to manufacture over 100 million of these adjustable spanners considered by many to be the best in the world, myself included. 127 years later Bahco now offer a wide range of adjustable spanners, some with extra wide jaws, some with polymer handles and one that even converts to a pipe wrench. But the models every RAC engineer should have in their tool kit are the 8071, 8072 & 8073 (8,10 & 12”). If you have never used a Bahco adjustable spanner you really don’t know what you are missing.

Rob’s review The jaws are the stand out feature on these spanners they hold onto the nut perfectly, instilling confidence in the user. They are lighter than you expect, yet fell incredibly strong. These spanners have gained iconic status and for good reason. They are outstanding at what they do.

Robs Review July 2016.indd 46

T

he Smartfit Glands are different from standard cable glands as they don’t require a locknut, you simply push & twist the gland into the 20 or 25mm hole until the splines click into place, tighten the outer lock nut, feed the cable through the gland before tightening the dome nut to secure cable in place.

Its that quick and incredibly easy. Much easier than using standard glands and locknut’s. Space is nearly always at a premium inside isolators and panels and always a fiddle trying to tighten up the locknut when next to another gland. To remove the glands you buy a separate pack of gland removers, pack 2 for 20 & 25mm glands. (£2.63 +VAT)

Rob’s review Every once in a while a product comes along and you think “That’s brilliant”. You are happy to pay the extra money it costs because it makes your life easier, and Smartfit Glands are one of those products. All the review crew thought they were excellent and happy to pay the extra money for them.

ABOUT

MANSFIELD POLLARD REVISITED

Just over a year ago, I met Bradford-based Mansfield Pollard’s Andrew Glen who had a recently started as the air movement solutions specialist’s new Sales and Marketing Director. I returned to see what had happened since first meeting him. Getting closer to customers

Mansfield Pollard’s car park, full of orders

Andrew Glen explained their different approach to positioning their proposition to customers. Mansfield Pollard has a huge amount of expertise in their sectors which, perhaps, they had not fully explained to all of their customers. Engineering expertise is one thing. But, having customers trust you is another. And, Mansfield Pollard’s leadership team has instilled a new culture of caring deeply about their customers and their challenges. It might sound trite, but Mansfield Pollard’s team have spent the last year or more getting closer to their customers. That means they are now invited to attend meetings with their customers’ clients to support them. That demonstrates a high level of trust which is hard-earned. That trust has come from delivering 100% ontime with all their projects so far, despite a changeable market.

I

t turns out that it has been quite a year for Mansfield Pollard, who design, build and install bespoke, air handling, kitchen ventilation, vibration and acoustic control solutions, Andrew told me.

In fact, their kitchen ventilation business has almost doubled, they are “flat out” with air handling solution orders, and they are picking up new business from existing and new customers nicely. What’s changed? I asked.

The strategy has taken time to embed itself in the company, but it is paying off. One glaring example struck me as soon as I arrived at their factory. There is so much more new business coming in that the main car park is now almost a no-go zone because of the orders waiting to go out to client sites. Mansfield Pollard core business is air management expertise. There are plenty of air management companies in the market. How do they differentiate themselves so that conversations don’t just come down to price? Andrew Glen explained that having a strong relationship built on trust and helping their customers is why they have been so successful. Talking solely about price could be seen as a failure for the company’s sales team. For example, a typical conversation about a new air management solution will focus on how their solution can be funded by the efficiency savings they will make. Andrew explained the background to the changes since I last met him: “We have taken a measured approach to the implementation of our business improvement agenda. “Our Kitchen Ventilation business unit was the first one to benefit from our activities and the relatively short leadtimes in that market have enabled us to see a positive impact on our sales numbers. For the twelve months ending 31 December 2015 sales were up over 230% compared to the previous year.

“The projects in our Vibration and Acoustic Control and Air Handling business units typically have much longer lead-times between the initial enquiry and the placing of an order however we are seeing significantly increased levels of activity in respect of the value of the projects in both business units although, as yet year on year sales growth, is more modest and in double digits.” It is not just about how they work with their customers and growing sales which is making the business so successful. Andrew explained there is little or no waste in the manufacturing. Well designed products which are fit for purpose means they can get their air management,

kitchen ventilation, and vibration & acoustic control products out on time and profitably. It sounds so simple. But, it is surprising how many businesses design products badly and are late delivering them to customers.

Experienced but not complacent

Mansfield Pollard has a long history. In fact, the company celebrates its 150th anniversary this year. Most companies don’t make it beyond their first year. Those that survive that long, generally, last around 20 years. A century and a half in business says a lot about this Bradford-based company. The company now turns over £16 million a year. Andrew reckons the UK air handling market is around £120 million a year. That’s pretty good market share. And, the team is not complacent either. This year Mansfield Pollard is rebranding to reflect the changing nature of the sectors it serves. Andrew gave me a sneak preview of how the business will communicate its proposition to its customers. Like all good marketing, the messages, images and branding were simple, clear and stood out. Customers will easily know how the company can help them. Andrew concluded: “Overall I’m very confident that the work which we have undertaken and will continue to undertake to bring our business closer to our customer is going to pay dividends in terms of long term growth for Mansfield Pollard and real added value for our clients.”

JULY/AUGUST 2016

SLOW RECOVERY FOR AIR CONDITIONING MARKET PREDICTED The global air conditioning market had a tough year in 2015 and it will recover more slowly than predicted, according to a recent report from BSRIA.

T

he BSRIA report showed that the global market declined by 5% in volume in 2015, after a 7% growth in 2014. Sales in 2014 were boosted by the market in the Asia Pacific region. The decline in 2015 was due to a decline in the same region. Asia Pacific accounts for 61% of the global packaged air conditioning (PAC) market. which dropped by 5% by volume. The markets in China, Japan, Indonesia and Korea, the four biggest markets, all declined. China has had challenging year with its economy growing at a slowest rate for 25 years. This had a knock-on effect across the globe impacting stock markets which all declined as a result of the tightening economy in China. The decline impacted the PAC market which dropped to 49.3 million units, a 7% drop on 2014. The market for mini-VRF (20kW) systems grew because of growing demand for residential systems. Saziye Dickson, Senior Market Research Consultant, WMI, said: “The bit of good news from the region came from Vietnam, Australia and

Philippines. The growing GDP and attractive economic characteristics mean the Vietnamese market has good potential for Foreign Direct Investments”. The air conditioning market in the Americas also dropped in volume to 27.4 million units in 2015, down by 2%. The market in Brazil dropped by 18% on the previous year when it grew by 28% over 2014. This was offset to a degree b growth in the USA market where PAC unit sales grew by 4% to 16.1 million units. The USA economy is strong which accounted for the growth.

European Air Conditioning Market

The air conditioning market in Europe was stronger where it grew by 2% in 2015, against a drop of 16% the year before. Hot summers and demands for energy efficiency drove demand for new systems in Europe. Demand for air conditioning grew in Spain, France, Italy, Turkey, Greece, Sweden and Germany. Russia, the biggest PAC market, dropped by 18% in 2015. The country faced a tough economy with a 50% currency devaluation and low oil prices, on which it heavily relies.

The Market in the Middle East, India and Africa (MEIA)

The MEIA market grew in 2015 from 11.6 million units to 12.5 million units. India was the country with the biggest growth in air conditioning (4% and four million units). Nigeria, Saudi Arabia and Egypt all grew, as did the markets in Iran, Bangladesh and South Africa. But, the air conditioning markets in the UAE, Kuwait and Qatar were flat, which was the result of low oil prices too.

Window and Through-Wall AirConditioning Market

The Window and Through-Wall air conditioning market grew by 2% in volume, which was 12 million units and US$2.6 billion. Most of the sales growth was from the USA (4%) and Saudi Arabia (14%) in 2015. These countries make up 60% of the global market. The USA had warm, late summer which pushed sales up, coupled with lower pricing on window air conditioning units compared to splits in Saudi Arabia. BSRIA does not expect this market to grow in 2016.

BSS scores double top in safety awards

Dimplex, and other manufacturers, have recently contributed to a free Eurovent Air Curtains Guidebook. The guide will help consultants, specifiers and engineers with choosing, installing and maintaining air curtains. The air curtains guidebook is a practical look at types of air curtain technologies available on the market, including their application and benefits. Dimplex and the other manufacturers across Europe, have worked with Eurovent to develop a ‘state of the art’ testing and efficeicny rating scheme. Also, the group made an in-depth study of the air curtains market with Eurovent Market Intelligence.

BSS, the UK’s top distributor of heating and pipeline products and services, has won major awards in recognition of its contribution towards health and safety from the Royal Society for the Prevention of Accidents (RoSPA). BSS won the ‘the Safety Initiative of the Year’ award for its ‘LiFT’ safety programme. The developed the LiFT programme to cut manual handling accidents and injuries. The scheme worked by asking all BSS staff to come up with ways to avoid lifting completely and then communicating these throughout its branch network. The result was not simply fewer accidents but also improved customer service as time was freed up for other tasks.

Carrier Rental Systems invests in new high-performance chiller fleet

Weatherite Launches High Efficiency Cabin Cooler Solutions

Following increased demand for temporary cooling plant, hire specialist Carrier Rental Systems has invested in a new fleet of high-performance chillers for deployment across the UK. Carrier has made additions to its medium- and high-capacity machines, spanning 220 to 400-plus kW of cooling, and new model sizes at the small end of the range to cater to applications with modest cooling requirements. “When existing cooling equipment breaks down, particularly in critical applications such as hospitals, data centres and process cooling situations, it is vital to ensure replacement chillers are in place and working as soon as possible,” said Marc White, director, Carrier Rental Systems.

Weatherite, has launched its energy efficient Cabin Cooling solutions for telecom cabins, switchgear and equipment rooms. The units are self-contained incorporating; filtration, modulating direct free cooling, DX back up (complete with DX cooling coil, compressor and DX condenser) and fully optimised Trend control systems. The units can easily be installed, without the need for complex integration, into wider systems- making them ideal for outdoor cabins, shelters, computer rooms, relocatable equipment buildings and telecom base stations. Weatherite has considerable expertise in ‘Free Cooling’ technology and the space-saving systems maximise energy reduction in small to mid-sized data rooms meaning more cooling for less power and ensuring a stable environment around the clock.

IMI’s Intelligent Control Valve System Saves Money and Energy IMI Hydronic Engineering has created a brand new solution to the problems caused by inaccurate control technology in heating or cooling systems. Uncomfortable temperature oscillations, noisy systems, and expensive and unsustainable energy bills are all a thing of the past with the new TA-Modulator - a highly precise pressure independent balancing and control valve – in conjunction with a range of fully digitally configurable actuators TA-Slider. The built-in pressure controller protects the valve against pressure fluctuations in the installation, keeps the temperature control highly stable, and minimises the number of actuator movements, prolonging its longevity.

The money will contribute to a new, powered electric wheelchair for Megan, which will improve quality of life and mobility. The All Star XI raises money throughout the North East through football matches with celebrities and professional players in the teams.

INTEGRAL SUPPORTS YOUNG PEOPLE WITH COLD ROOM FOR HOSPICE Intergal’s refrigeration team in Leicester, has helped the East Midlands charity, the Rainbows Hospice for Children and Young People installing a new and improved cold room for their kitchen. The charity helps ‘life-limited’ children and their parents with care and support, helping to improve their quality of life. The charity helps 300 people in the region. The kitchen provides foods to help with special dietary requirements. The existing equipment was unreliable and was not adequate enough for what they needed. They needed a larger cold room to be able to stock and provide the wide range of foods for the young people and children. In April, Integral approved the scheme to remove the old cold room, supply and install the new one as a charitable donation. Integral worked with selected suppliers and contractors to make the installation possible. The team installed the new cold room over a Bank Holiday weekend by a team of volunteers from Integral and their suppliers, Dean & Wood, ACM, Gibson, CEW, HSS Hire, TVR and NES. Kate Golding, Head of Giving at Rainbows said: “The new fridge is amazing and will make such a difference to us.”
