Poor indoor air quality: what are the signs?

Healthy air keeps us happy and healthy. Here’s what to watch out for and steps to take to improve the air quality in your home The average person spends 90 per cent of their time indoors, and over 60 per cent of time in the home – and that’s during our waking hours. If the air inside our homes is polluted, our health can be negatively impacted. So, what are the signs of low air quality?

Although there are many indicators of poor air quality, these indicators can be early signs that the air in your home could be improved.

Bad odours

Unsurprisingly, this is one of the first signs of poor air quality. Bad smells can result from various sources including animal dander, cooking and mould growth.

Identify where the odour is stemming from and treat it at the source to combat the unpleasant smell and improve the home’s air quality.

Hot or cold spots

Hot or cold spots are the result of uneven temperature distribution and another indication of indoor air quality that could be improved. Making the temperature more uniform throughout your home will help to address the unstable indoor air caused by large fluctuations in temperature.

High humidity

can also encourage the growth of mould and mildew.

High levels of humidity can be the result of external factors such as the weather, or activities within the home such as cooking or showering. Reducing humidity means lower moisture levels and a more stable indoor environment.

Dust

Dust mites, pollen, microplastics and bacteria all contribute to poor air quality. Maintaining a dust-free, clean home will improve the air around you and your family.

Physical symptoms

Our bodies can also indicate poor air quality around us – allergic episodes, allergy irritation, headaches, fatigue, dizziness, irritated or dry skin, and coughing are all symptoms that might be experienced. While each symptom can be caused by other factors and it’s important to consult a doctor, they are also indicators that the environment around us is not healthy.

Lots of factors impact the quality of the air inside our homes. Thankfully, heat pumps and air conditioners can help heat and cool our homes, maintain a comfortable level of humidity and mitigate health risks with the best possible air quality.

Excessive humidity can be uncomfortable to live in and

Another champion named

Six apprentices showcased their skills at the Wallie Askew Memorial Workskills Competition last month irhace.org.nz

“There were two reasons for the change of rules,” says Gina McMaster, CEO, IRHACE and CCCANZ. “To allow apprentices to enter more than once encourages the younger apprentices to enter. The second reason is that, with competitors entering more than once, the level of competition rises as they should be better prepared.”

This was the case for Liam McVicar from McAlpine Hussmann, Wellington, who took out first place in this year’s challenge after first competing last year.

Newcomers Dylan Hendry (McAlpine Hussmann, Dunedin) and Matt Jackson (Active Refrigeration, Christchurch), placed second and third, respectively.

Campbell Brown (McAlpine Hussmann, Tauranga), Dylan Hendry (McAlpine Hussmann, Dunedin), Oliver Tischendorf, Dobsons Refrigeration & Electrical, Te Puke), and Tristran Munro (Excel Refrigeration & Air Conditioning, Wellington), also impressed the judges – David Everett, Cameron Wilson-Meek, Daniel Jordan, Neill Adkins, Elias McKenzie, Lee Todd and Rodger Wyatt.

WorldSkills New Zealand’s Operations Coordinator, Sally Gray, was also there to support the apprentices.

Showcasing their skills in both practical and theory, day one of the competition saw the apprentices fly through their practical assessment before starting theory and electrical fault finding in the second half of day two.

Held annually, the Wallie Askew Memorial Workskills Competition is about coming together as an industry and supporting those early on in their HVAC&R careers.

A huge thank you to our major sponsors RealCold and CCCANZ. Following three successful regional rounds of the competition – where a record number of apprentices competed – the 2024 Wallie Askew Memorial Workskills Competition has wrapped up with new winners announced.

As well as having a record number of apprentices competing at the regionals, this was the first year apprentices could enter the competition again if they’d previously been involved.

A special thanks to Steelfort Engineering and John Jenkins for hosting the final competition, and to our judges and volunteers – none of this would be possible without your support.

Our journey to WorldSkills HVAC&R Centre’s Gina McMaster shares how New Zealand came to be representing the world stage in HVAC&R with the help of IRHACE Words by Gina McMaster, CEO IRHACE and CCCANZ

It was a dream and one that had been talked about over the years. But there was a lot to overcome.

Back in 2021, the IRHACE Council wanted to provide both a high-performance and development pathway for our apprentices. No one could get it across the line and so it just didn’t get the push and determination for the project to succeed.

With my background in sport, I know how important it is to have these pathways and I have succeeded in these journeys with other organisations.

The most important thing is to have a plan. It started with the restructuring of the existing Wallie Askew Memorial Workskills Competition.

At WorldSkills, the skill is ‘Refrigeration and Air Conditioning’ and this is what we were going to need to change to bring in the other components. The international competition also has different scoring – another change to bring in to give us a more consistent and structured approach. While this wasn’t a popular move to start with, the industry has seen the positive and is supportive of the change.

irhace.org.nz Daikin Team

NOVEMBER 2024

IRHACE established the Apprentices of IRHACE special interest group and at the helm is David Everett. With assistance from Trent McDonald, David put together a team that includes John Jenkins, Neill Adkins, Daniel Jordan and Phil Mohan to steer the competition’s change.

Along with this came the mentoring group which now includes Cameron Wilson-Meek (winner in 2022), Alex Davies (2023 winner) and Jack Butler (first WorldSkills representative) who have all given back to the industry in judging and presentations to the competitors.

Our partnership with WorldSkills NZ covers the promotion and showcase of the refrigeration and air conditioning industry to stakeholders and the public as well as other areas of cooperation. This venture enabled us to put forward an apprentice to represent New Zealand on the world stage. With the partnership and special interest group established, we now needed to attract more entries into the competition. The changes to the rules have allowed competitors to enter from Year 1 to Year 4 of their apprenticeship and enter more than once. This has occurred for the first time in the 2024 competition with a record number of entries.

Our operations team has worked tirelessly in the background, contacting companies to encourage entries and also to get support from the industry. Realcold has now been the major sponsor of the event for the last two years and there is continual support from CCCANZ. Our companies and educational institutes have assisted with venues and suppliers have provided equipment and prize support.

But the crunch came when our first apprentice, Jack Butler from Active Refrigeration, was selected to compete globally – IRHACE had to fully commit to being able to fund not only the WorldSkills leg but also the Melbourne competition.

RLNZ stepped up and provided sponsorship for the Australian part of the competition and Active Refrigeration has sponsored the WorldSkills aspect.

Craig Duff, a long-time IRHACE member and Founding Director of Active, commented on this part of the journey saying, “What an amazing journey for you all to be on, and for Active on the world stage. What a proud moment. Well done all.”

WorldSkills is a competition at another level – the Olympics for our trade. It is such a great experience no matter where competitors finish. Jack has made New Zealand proud and put our industry on the world map.

Is the grass greener?

It’s a question New Zealand’s Workforce Development Council, Waihanga Ara Rau, recently posed in a media release about Kiwi workers jumping across the ditch It’s a long-held belief that Australia offers better financial opportunities for New Zealanders in the construction and infrastructure sectors. However, new research suggests this may no longer be the case. Instead, the study finds that shrinking income disparities, higher taxes and soaring house prices are making Australia a less attractive destination for many Kiwi workers looking to relocate.

The Construction and Infrastructure Workforce Development Council, Waihanga Ara Rau, commissioned Allen + Clarke to conduct this research on their behalf. Is the grass really greener? combines quantitative analysis and interviews with returning workers to offer a detailed comparison of key factors influencing relocation decisions, including income levels, housing affordability and costs of living.

Kiwi wages on par with Australia for Electricians, Telecoms workers Among the findings, it shows electricians and telecoms workers in Victoria and New South Wales are no longer likely to earn significantly more than their counterparts in New Zealand, and may even take home less after-tax income. For construction workers and heavy machinery operators, it reveals that although earnings remain higher in Australia, they come at the cost of overtime and weekend hours.

Zealand workers considering a move across the Tasman: “This research isn’t about claiming one country is better.

It’s about giving workers and employers complete information. Relocating involves more than just a paycheck, with taxes, living costs, and work-life balance all playing a role. Both sides need to understand the trade-offs.”

Workers prefer Aotearoa to bring up families The research finds that stage of life also plays a critical role in decisions to move to Australia, with the country remaining most appealing to younger Kiwis early in their careers, especially those without children or mortgages.

Australia’s larger job market and opportunities for career progression, combined with overtime and penalty rates, continue to draw those seeking a ‘Tradie OE’.

In contrast, New Zealand becomes more attractive as workers progress through their careers, start families, and seek greater stability. With improving housing affordability and a better work-life balance, the report finds that New Zealand offers strong incentives for those looking to settle down long-term.

Building a career in HVAC&R Our trade has a new Level 5 qualification to better upskill the workforce in an area essential to our daily lives The HVAC&R sector is essential to various aspects of our day-to-day, and the economy. With its rapid growth, the demand for skilled professionals in refrigeration engineering is crucial to support the New Zealand economy.

Mechanical service systems may include environmental control systems; air conditioning and heating systems; specialist ventilation and fluid conveyancing systems; non-potable water systems; and medical and laboratory gas systems.

HVAC&R Centre works hard to encourage new apprentices into the industry and assist with the development of those already qualified.

This qualification is a Level 4 certificate worth 280 credits.

HVAC&R qualifications in New Zealand Air Conditioning Installation (Level 4) Air conditioning technicians need to have a good fitness level and be strong as they may need to carry heavy tools and equipment. Qualified air conditioning technicians must be registered and licensed with the Electrical Workers Registration Board. This qualification programme focuses on the types of commercial and residential units commonly installed, including ducted systems and variable refrigerant flow units. Installation covers the requirements of seismic restraints, passive fire, and retaining the structural integrity of buildings, among others.

Air Conditioning Installation Level 4 is a two-year certificate worth 140 credits.

New Zealand Certificate in Mechanical Building Services, Trade (Level 4) Mechanical building services engineers install and maintain the heating, ventilation, air conditioning and environmental control systems used in offices, hospitals, supermarkets and other businesses. You can either train through an on-the-job apprentice or tertiary institutes and are likely to work in a variety of locations.

New Zealand Certificate in Refrigeration and Air Conditioning, Trade (Level 4) Entry to this course is open, however, it is recommended candidates hold the National Certificate in Educational Achievement (Level 2). The purpose of this qualification is to provide the HVAC industry with skilled tradespeople who can independently install, maintain, service and commission plant and equipment to industry standards.

The certificate is Level 4, worth 280 credits.

New Zealand Certificate in Mechanical Engineering, Advanced (Level 5) This qualification is designed for people who have already completed a mechanical engineering-related Level 4 trade qualification and wish to further develop their technical and/or operational knowledge and skills within their chosen discipline of mechanical engineering, construction, manufacturing, fabrication, refrigeration and air conditioning, and mechanical building services.

From the farm to France A can-do attitude and farm fix-it skills helped this apprentice succeed in Lyon At the 47th WorldSkills International Competition in Lyon, Jack Butler proved his skills – showcasing his ability to work in a high-pressure environment, perform complex tasks including installing and piping key components like condensing units and wall-mounted evaporators, diagnosing and repairing electrical and AC faults, and fabricating a copper sub-cooler with expert precision.

“The whole experience was incredible and beyond what I could ever imagine,” says the 20-year-old from Urenui.

“Meeting people from around the world and seeing where we stand compared to the rest was a real highlight. It was really cool to see that we, as New Zealanders, are in the top end of our trade.”

Described as a once-in-a-lifetime opportunity, Jack spent 12 months training for the event, building his competition skills at the 2023 Wallie Askew Memorial Workskills Competition where he placed first in the regional challenge and second in the final competition – securing his spot for Lyon as well as the WorldSkills Australia Global Skills Challenge in Melbourne, where he took out silver.

“I was lucky enough to have Active Refrigeration backing and supporting me the whole journey and pushing me to do my best, putting me through any training I needed and building replica training units from past WorldSkills competitions.”

Events like this are close to the heart of Jack’s boss William Lovell. He, too, has achieved success in the Wallie Askew Memorial Workskills Competition and is a big fan of the benefits they bring.

“Competitions are a great opportunity to put your skills to the test against fellow apprentices and a way to advance in skillset and personal development,” says William, who accompanied Jack to Lyon and described the opportunity as a career highlight.

“I can’t even explain how proud I am of Jack. From what

irhace.org.nz

NOVEMBER 2024

I’ve seen him achieve in the past four years, I can only imagine how far he will go in the industry.”

William believes Jack’s dedication, enthusiasm and interest in embracing new challenges set him apart in the sector. ”He has a Kiwi can-do attitude and is always looking forward to how he can further progress his career. What impresses me most is his attention to detail and his willingness to always improve and progress in his skillset.”

Competenz Training Advisor Angus Ryburn was part of the team that saw Jack gain his apprenticeship qualification, and he reckons Jack is a perfect fit for the sector.

“Jack is cool-headed and even-tempered. This allows him to logically deal with and work through the requirements of whatever challenges he faces,” says Angus. “He’s not driven by ego, but a desire to do the right thing by the team and customer and get the job done safely, timely and effectively. A future leader for sure.”

That’s music to Jack’s ears. Why? Because he can’t imagine doing anything else.

“I was brought up on a farm where my dad always had a project in the shed, so from a young kid, I’ve always been keen on building things and pulling things apart to see how they work,” explains Jack.

“Growing up, I wanted to be an engineer but soon realised I didn’t want to be stuck in a workshop all day doing the same thing. At high school, I was given the chance to do work experience with Active Refrigeration and have never looked back. Within our trade, there’s so much variety – one day, you’ll be Tig welding stainless pipe; the next, you’ll be fault-finding electrical, and the next, you’re servicing refrigeration equipment. Every day is different, and that’s the best part of the job.”

The lowdown on Hybrid Variable Refrigerant Flow (HVRF) systems These air conditioning systems combine the advantages of traditional VRF systems with advanced chiller technology Energy efficiency is one of the major drawcards of HVRF systems, making them a popular choice as the demand for environmental responsibility grows.

Unlike conventional HVAC systems that rely solely on refrigerant lines, HVRF systems incorporate water lines.

The systems operate by replacing refrigerant with water between the hybrid branch circuit controller and the indoor units – minimising the need for expensive and ongoing leak detection servicing.

The design makes HVRF systems ideal for occupied spaces where quiet, energy-efficient, simultaneous heating and cooling is valued.

The benefits of Hybrid Variable Refrigerant Flow (HVRF) systems

Flexibility These systems also provide flexible zone control with different indoor units able to operate on heating or cooling at the same time. This is ideal for multi-tenant office buildings and hotels – individual zones can be adjusted to meet specific needs, enhancing comfort without sacrificing efficiency. However, it’s important to plan your installation – ductwork retrofitting and disruptions during installation can be experienced when adding an HVRF system to an existing building.

Case study highlight An HVRF system was the right choice for a mid-sized office building in central Christchurch, which was recently installed by Beattie Air. The transition from a conventional HVAC system to a Mitsubishi Electric HVRF system was made to reduce operating costs and temperature inconsistencies.

Cost savings and energy efficiency One of the main reasons for a switch to an HVRF system is for increased energy efficiency. Compared to traditional systems where energy can be wasted by heating and cooling different areas independently, HVRF systems balance this simultaneously. The use of less energy also has a positive impact on the environment.

No refrigerant concentration limits By cooling and heating with water instead of refrigerant, HVRF systems can be used for most commercial buildings including hotels, offices, educational buildings, and hospitals and medical centres.

The results •

A 30 per cent reduction in energy usage was seen within the first year.

•

There was a 50 per cent drop in complaints about temperature inconsistencies.

•

Improved system reliability paired with fewer mechanical issues has decreased maintenance costs.

•

The building’s overall safety has been improved thanks to the reduced use of high-pressure refrigerant lines.

A convenient reclaim cylinder exchange initiative A-Gas has partnered with Actrol to increase refrigerant recovery in New Zealand The responsible management of used refrigerants plays a vital role in reducing emissions. While is it illegal in New Zealand to intentionally release refrigerants into the atmosphere, venting unfortunately still frequently occurs.

That’s why A-Gas, a global enabler of lifecycle refrigerant management, has partnered with Actrol, a leading refrigeration wholesaler in New Zealand and Australia to support the industry in increasing refrigerant recovery rates.

“A-Gas is committed to capturing gas for future re-use, preventing its harmful release into the atmosphere,” says A-Gas New Zealand General Manager, Mitchell Williamson. “We are excited to partner with Actrol in New Zealand to introduce a reclaim cylinder exchange initiative for their customers. This collaboration demonstrates our shared commitment to protecting our environment for a sustainable future.”

Recovering used refrigerants reduces their potential impact on the environment. The new Actrol Reclaim Refrigerant Programme offers a seamless process for managing used refrigerant, eliminating the need and cost of owning their own reclaim cylinders for customers.

HVAC and refrigeration technicians can easily visit one of Actrol’s nine branches located throughout New Zealand to collect a free reclaim cylinder. Once the cylinder is full, customers can return it to an Actrol branch and exchange it for an empty, vacuumed and approved reclaim cylinder ready for the next recovery. From there, Actrol sends the recovered refrigerants to A-Gas for processing.

To make the process even easier, technicians can track their cylinder fleet through Actrol’s Flexitrak app to see their current stock and reclaim history.

Here’s how it works: 1. Visit your nearest Actrol store to pick up a free reclaim cylinder.

2. Recover refrigerant from the system or vessel into the reclaim cylinder.

3. Return the full reclaim cylinder to an Actrol branch.

4. Your Actrol account will automatically be credited once the refrigerant is decanted.

5. It’s as simple as that – earn money back for every reclaimed cylinder and help prevent the release of gases into the atmosphere. Every gram counts.

By providing technicians with a convenient and easy way to manage used refrigerant, this initiative seeks to contribute to the reduction of greenhouse gas emissions associated with improper and illegal refrigerant disposal.

The Actrol Reclaim Refrigerant Programme is now available to account customers at Actrol branches throughout New Zealand.

Start your environmentally responsible journey by downloading Actrol’s Flexitrak app here http://www.actrol.com.au/flexitrak.

“Our partnership with A-Gas represents our continued commitment to being one step ahead of our customers’ needs. This programme is designed to be convenient for our customers and rewards them with incentives, empowering them to easily minimise their impact on the environment. We’ve been offering this service in Australia for several years and expanding it to New Zealand gives local customers added convenience to safely dispose of used refrigerants,” says Mark Helliar, Category Manager, Refrigeration, Actrol.

The Actrol Reclaim Refrigerant Program allows technicians to earn money back for every reclaim through a simple cylinder swap initiative.

Long-term efficiency and health

All heat pump/air conditioning systems are different, with many parts integral to their operation. Hiring a professional HVAC technician provides peace of mind that the service or repair will be addressed by an expert.

It’s important to always ensure your technician has the right New Zealand licencing, which must be held by any person carrying out work on air conditioning and heat pump equipment. You can easily find a professional on the HVAC&R Centre website.

A professional service is recommended every one to two years, depending on usage, to ensure the system operates as smoothly as possible. Regular servicing also helps pick up any potential issues before they become major problems. A clean HVAC system is beneficial to your health as the system won’t circulate unclean air.

Air conditioning fit-out for a residential apartment complex in Tauranga All Seasons Air Conditioning worked with Daikin to install air conditioning units across four levels of residential apartments and one level of commercial space at a new, premium mixed-use development located in the heart of Tauranga city Daikin dealer, All Seasons Air Conditioning, was approached to carry out a design and construct project, providing a premium air conditioning solution for the multi-use Vantage building development. Each apartment was required to have its own power bill, which includes the cost of air conditioning based on usage. Maintaining a sleek aesthetic was also a key part of the brief – with each apartment featuring floor-to-ceiling windows and high ceilings, there was a need for controlled air supply, however, the client wished to ensure any units wouldn’t impede on the open kitchen/living room spaces.

For the ground-level commercial tenancies, the air conditioning system needed to be adaptable to accommodate future layouts and fit within the limited space available – balconies, the roof, and parking lot spaces were off limits for the installation of the condensers.

The solution

Daikin VRV systems were chosen to provide a comprehensive solution for the building’s air conditioning needs.

For the apartments Each floor of residential apartments has been equipped with: •

•

Single VRV R Heat Recovery (REYQ-TAY1) condenser paired with either a cassette (FXFSQ-AVM) or mid-static ducted (FXSQ-PAVE) indoor units, multiport BS box and BRC1E63 ‘Nav Ease’ wall mounted controllers.

Single VRV H Heat Pump (RXYQ-AYM) condenser with Outdoor Air Processing unit (FXMQ-MFV1) for tempered outdoor air supply.

VRV R Heat Recovery systems comprise of a single outdoor unit with vertical discharge, a branch selector box and multiple indoor units, allowing for flexibility with simultaneous cooling and heating operations.

To accommodate this project’s aesthetic requirements and tight ceiling spaces, round flow cassette indoor units with sensing (FXFSQ-AVM) were selected for the living rooms of lower-level apartments. For a discreet, sleek look, FXSQ-PAVE ducted slim mid-static units were used for the penthouses – leaving visible only the supply diffusers and return air grille.

The ease of installation and maintenance, along with individually adjustable airflow direction for each air discharge outlet, ensures optimal air distribution throughout each room.

For the commercial spaces The commercial tenancy spaces have been equipped with three VRV R Heat Recovery (REYQ-TAY1) condensers, multiport BS boxes, cassette (FXFSQ-AVM), high static ducted units (FXMQ-PAVE) and BRC1E63 wall-mounted controllers.

In addition, an ITM central controller with an activated Power Proportional Distribution (PPD) function has been installed. This feature allows for efficient energy monitoring and accurate billing for the tenancies.

Control solutions Intelligent Touch Manager (iTM), Daikin’s advanced central controller was installed in the main switchboard. iTM allows efficient control over all the air conditioning systems in the building. Additionally, the Power Proportional Distribution (PPD) function enables monitoring of power consumption for each indoor unit to assist with calculating electricity bills for every apartment or tenancy.

BRC1E63 wall-mounted controllers were chosen to be installed in the apartments’ living rooms/tenancies for convenience and comfort. These controllers come equipped with a built-in temperature sensor and a range of user-friendly functions from setting the perfect temperature and airflow rate to creating a weekly schedule and utilising the off-timer.

All Seasons Air Conditioning’s collaboration with Daikin’s latest product resulted in a successful design and construction solution for this commercial tenancy and luxury apartment development, meeting all the customer’s specific requirements. Close collaboration with the builder and other contractors on site ensured the seamless and timely delivery of this project. daikin.co.nz allseasonsair.co.nz
