CASE STUDY

Sustainable Pub Leading the Way with Choice of HVAC Technology

Sparkke @ The Whitmore Project Address 317 Morphett Street, Adelaide SA 5000 Mechanical Contractor John Bossy Refrigeration Equipment 2x Climate Wizard CW-P15 units.

Sparkke at the Whitmore is Australia’s first female founded and led brew pub, boasting a generous rooftop bar and alfresco dining. The Whitmore is driven by their inspirational values – ensuring everyone can expect a warm, safe welcoming experience with a passion of excellence being clearly visible. Combining food and beverage options, events and artists, Sparkke at the Whitmore is a standout award winning venue.

In line with the venue’s philosophies, coowners Kari Allen and Rose Kentish, wanted a sustainable cooling solution that would introduce fresh outside air through the building, maintaining comfort conditions for up to 300 occupants.

Challenges

Project Requirements

•

Maintain comfort conditions in the front bar dining room at a space temperature of 24-26° degrees Celsius.

•

Provide a cooling system that was energy efficient and one which reduced peak • demand.

HVAC&R News

www.airah.org.au/hvacrnews

•

Due to the placement of the units, above the open-air beer garden, a quiet solution was required. Minimal electrical infrastructure.

The Solution

•

Minimise the required electrical infrastructure on-site.

•

Provide fresh outside air and ventilation for 300 occupants at 7.5 – 10 Litres per second per occupant.

After an extensive evaluation and selection process, Climate Wizard air conditioning technology was selected by the owners, as the most efficient solution.

•

Positively pressurise the space to stop outside air infiltration in the dining room front bar.

2x Climate Wizard P15 units were installed, with a spiral duct running along the interior of the building. This added to the aesthetics

With half of the venue heritage listed it was vital that characteristic and charm remained, while implementing major environmental enhancements to all areas of the pub, including water, light, power and access for all people.

The CW-P15 units needed to be installed on a platform on Level 1.

•

A recent renovation included the addition of the rooftop bar, an upstairs function area and downstairs an inhouse nano-brewery with beer garden.

Maintaining the aesthetics of the heritage listed building presented a challenge, amongst others: • As the building has a roof top bar, there was limited space to install the two CWP15 air conditioning units.

February–March 2022

of the building whilst also providing a solution for the limited installation space. The smaller footprint of the CWP15 units allowed for placement on the small area of roof space that remained out of sight.

ADVERTORIAL

The larger open areas in the space had to be positively pressurised while minimising energy consumption. This presented another challenge due to the doors opening to rooftop bar and beer garden. Fortunately, Climate Wizard thrives in this sort of environment and this issue was quickly resolved, distributing air evenly throughout the dining and bar areas which is then relieved into the outdoor entertainment area.

Results The client is extremely happy with the final result and the cool air temperatures and comfort levels that the Climate Wizard units are delivering. They have also noted that the Climate Wizard units’ energy savings and low emissions have supported the launch of their first carbon neutral beer.

Ed’s letter

A CHILLED CHRISTMAS ’Twas the night before Christmas and all through the house, not a creature was stirring … except for my son, who was complaining that the ice-cream in the freezer was runny.

We all know the way things are going. It’s no secret. Manufacturers seem more focused on making their products reliably fail after a certain period, rather than building them to last. And if you’re familiar with the Right to Repair movement, you’ll know the kinds of stunts they pull to make sure there is no possible fix.

Sure enough, something was wrong with the fridge. The lights were on, but it wasn’t cold. I put my hand on top to see whether it was warm, as it usually is when it’s rejecting heat. Cool to the touch. I pressed my ear against the side to listen for the compressor. Nothing. While I cursed Murphy and his law, I fiddled with the temperature nobs and started reorganising all the food we’d bought for Christmas – now going warm. Eventually the compressor jumped into life again and cool air started flowing out of the vents. Let’s just say I didn’t sleep soundly that night, and it wasn’t because I was waiting up for Santa.

The other day one of our readers sent in a photo of an old Muller unit that was still operational. He was wondering if we could date it. We popped it on AIRAH’s Facebook and LinkedIn pages and asked the question. One person said that, from the serial number, it was probably made in 1942.

Christmas passed with no dramas, and next business day I called a technician. He ran some basic checks, but said there wasn’t much more he could do, given that the fridge was working and the fault was intermittent. We could contact the manufacturer, who could open the system to check the refrigerant levels, but the service and repair would likely cost more than a new fridge. After seven years, ours was – surprise surprise – just out of warranty.

Yep, 80 years old. Still running. Some may point out that a company will go out of business if its products never fail. Fair enough. What if we changed the system? Microsoft and other software companies have successfully moved to a model where you pay a yearly subscription, and get

continuous upgrades. Could manufacturers do the same? Would you pay a yearly fee if it entitled you to ongoing repairs and service? And if the company replaced the parts or the entire unit when necessary, and recycled it properly? I’d be interested. Anyway, on with the show and our first issue for 2022 – our refrigeration and refrigerants special. You might have noticed a change on the cover. We’ve renamed the magazine HVAC&R News to match our www.hvacrnews.com.au website. Different name, but same aim – to keep you up to date with our sector. Hope you enjoy it. ■ @AIRAHnews

HydroChem has sought to differentiate its most popular HydroBalance products from similar products in the Australian market by submitting itself to the Australian Made process. The company has received the Australian Owned and Made tick of approval for Wanda Wash, Bubble Up, No More Grease, Coilox, CoilKleen, 4X and Clean-Ice. “From a HydroChem perspective, the Australian Made program has become an imperative,” says HydroChem CEO Mike Lenton, Affil.AIRAH.

Now the iconic Aussie brand is offering the chance to win a trip for two to the 2022 Finke Desert Race. The winners will enjoy a VIP pit pass, getting into the nuts and bolts of the race with Toby Price, the 2021 Finke Desert Race winner and Blundstone ambassador. The prize also includes flights, accommodation and meals. The competition runs from January 10–February 20, 2022. “I’m proud to be a long-time Blundstone ambassador,” says Price. “I like to do my preparation and race with top-of-the-range gear, so I know a bit about the value of the original and best work boots. There is no race quite like Finke and I can’t wait to get out in the Red Centre to go racing again.”

Australian Made for maintenance

Water treatment specialist HydroChem has secured Australian Made certification for its HydroBalance HVAC&R maintenance range.

According to Panasonic, the Z Series units deliver improvements to energy efficiency with the AI-powered ECO mode. This auto‑adjusts to the optimal ECO level based on heat load conditions and air conditioning cooling capacity. An inverter control feature also varies the rotation speed of the compressor for higher energy savings.

The checklist also explores the concept of “Build Back Better”. This new approach to resilience focuses on implementing positive social change and improving the community capacity by viewing resilience not merely as an outcome but also as a process in itself.

Panasonic Australia has launched a new range of air conditioners with wi-fi and air purification features.

Rectorseal pops the caulk

Rectorseal has added Metacaulk cast-in-place device (CID) tub box kits to its product line, providing firestop penetration for plastic and metal drainpipes. Available with 2- and 3-inch Metacaulk CID, the tub box kits are designed to prevent the spread of fire from bathtubs or jet-spa drains to the upper level. No concrete drilling is required. The maximum slab height with kit components is 10 inches. For deeper slabs, Metacaulk CID extensions are available.

Panasonic takes the floor

Panasonic has released a floor-standing air purifier, featuring the company’s trade-marked nanoeX technology. “With the average person breathing in 18kg of air every day, air is an essential part of our lives,” says Panasonic. “The new range purifies the air with nanoeX, which actively cleans the air in the room, impacting upon airborne and surface impurities. OH radicals encapsulated in water neutralise micro-organisms and pollutants – inhibiting up to 99 per cent of bacteria, viruses, mould and allergens, both airborne and on surfaces, as well as reducing odours.”

“Our continuing quest is to provide products that help to reduce installation time,” says Caitlin Krc, Product Manager at RectorSeal. “It’s one reason why our tub box components are designed to be cast directly into the concrete to form an embedded intumescent service supply.”

BEHIND THE GREEN WALL

LINEAR ALTERNATIVE

A new study suggests retrofitting existing building walls with a living (green) wall could reduce heat loss by more than 30 per cent.

European tech company Magtor has developed a linear compressor that could cut energy use by 30 per cent and eliminate power spikes on start-up, making it a candidate to replace traditional rotary-based technology.

The researchers retrofitted a green wall at the UK’s University of Plymoth on a pre‑1970s building, and monitored the differences in heat lost between the retrofitted wall and a normal wall. Both had a west-facing elevation.

The motor is oil-free, as well as being smaller and lighter than reciprocating-pistonbased technology. According to the company, it also has fewer parts and less complexity, as well as shorter and cheaper production and assembly lines.

It was found that the retrofitted wall lost 31.4 per cent less heat than the wall on the original structure. It was also discovered that the temperature remained more stable behind the green wall.

“The heating and cooling industry was absolutely not in our sights when we started the Magtor project,” says company co-founder and CTO Jeremy Hein. “We initially intended to deliver a new kind of ‘electromagnetic piston’ converting electricity to linear mechanical motion by using ‘long distance’ magnetic attractive and repulsive forces between components that are always aligned and facing each other.

Lead author Dr Matthew Fox says that living walls could play a vital role in reducing energy use in older buildings. He estimates that 57 per cent of all buildings in England were built before 1964.

“It was when we wanted to test the Magtor motor that we came up with compression as a way to apply a load on the motor while effectively using its key characteristics.” ■

“It is our existing buildings that require the most energy to heat,” he says, “and are a significant contributor to carbon emissions.” Dr Fox says improving the thermal performance of existing buildings is essential.

CZECH REPUBLIC

SCHEMING THE CUBE

IN THE LOOP

Researchers at the University of California, Davis, have developed a new type of cooling cube that can keep food cold and fresh without relying on ice or traditional cooling packs.

The Czech Republic arm of Toyota Motor Manufacturing has passed on 295.2kg of R407C to Daikin’s Loop (L∞P) circular program to reclaim and reuse recovered refrigerants.

The cooling cubes are plastic-free, “jelly ice cubes” that do not melt. They are compostable and anti-microbial, and prevent cross-contamination. “When ice melts, it’s not reusable,” says Professor Gang Sun. “We thought we could make a so-called solid ice to serve as a cooling medium and be reusable.”

To reduce the production of new refrigerant, the reclaimed R407C will be reused for production of new HVAC devices. In addition, three decommissioned chiller units at the factory in Kolín – two from the painting shop and one for cooling the administration building – were replaced by new chillers using R32, a lower-GWP refrigerant.

To retain and stabilise their structure, the cooling cubes contain more than 90 per cent water and other components. Soft to the touch, they change colour depending on temperature.

“We are actively seeking out any opportunity to improve the environment, following a global corporate vision of zero emissions during the production of vehicles by 2050,” says Toyota’s Koreatsu Aoki.

These reusable cubes can be designed or cut to any shape and size required.

“Loop by Daikin is opening a new possibility for us to go even further in the recycling of all materials we use during our manufacturing processes, making production more sustainable.”

Says Sun: “You can use it for 13 hours for cooling, collect it, rinse it with water and put it in the freezer to freeze again for the next use.” A patent for the design and concept was filed in July.

Feature

STEPPING UP THE PHASE‑DOWN In January 2022 Australia passed another milestone in the phasing down of HFC refrigerants. Willow Aliento talks to industry experts about how the process is tracking – and where it could be improved. Program where aggregated data is publicly available,” says Patrick McInerney, Director Ozone and Climate Protection Section at the Department of Agriculture, Water and the Environment. “HFC import data feeds into the National Greenhouse Gas Inventory and greenhouse gas emissions projections. The Cold Hard Facts series also provides detailed analysis of the bank and emissions of refrigerants.”

The HVAC&R sector might not attract mainstream media coverage for its environmental achievements, but our contribution to protecting the Earth’s atmosphere is significant. The HFC phase-down builds on the collective success of taking ozone-destroying substances out of the supply chain, and will greatly reduce greenhouse gas emissions. If successful across the world, it could avoid up to a 0.5°C increase in global temperatures by the end of the century.

The phase-down is an important part of Australia’s emissions reduction commitment under the Paris Agreement, as well as the Montreal Protocol on Substances that Deplete the Ozone Layer.

While in many respects it is going well, some challenges remain in specific practices and applications. HFC (hydrofluorocarbon) refrigerants are being phased down globally due to their high global warming potential (GWP), with the Kigali Amendment to the Montreal Protocol specifying the targets and dates for achieving significant reductions. Australia cochaired the international negotiations, which set a target of 85 per cent reduction in HFC use by 2036 for developed nations. Australia started its phase-down on January 1, 2018. We have implemented it as a staged trajectory of reducing import quotas, which gave us a more rapid and consistent initial trajectory than other signatory nations. Australia’s HFC import limit is set in law and is controlled through a licensing and quota system. Since the HFC phase-down started in 2018, annual imports have been within the limits set in the legislation.

“Australia (also) reports its annual imports to the Ozone Secretariat in the United Nations Environment 12

HVAC&R News

“Our industry knows how it will tighten” he says. Peter Brodribb, M.AIRAH, is Managing Director of the Expert Group – the organisation that produces the Cold Hard Facts series of reports that contain key measures of Australia’s HVAC&R sector, in particular the refrigerant bank.

McInerney says that to date there have been no significant challenges.

He says that while we are on track, there could be a “clash point” when the Australian trajectory intersects with the Montreal Protocol trajectory in around 2029.

“Australian industry is used to the gradual phase-out/ down of these types of chemicals,” he says, “and has demonstrated it can manage the reducing availability while transitioning to alternatives.”

By then Australia will be on an equal path with Montreal, which has a phase-down limit of 3,244 megatonnes of CO2 for Australia within the agreement, while our national settings should have us at 3,200MtCO2.

He notes that Australia had already begun to move away from high-GWP HFCs well before the phase‑down started.

STUBBORN REFRIGERANTS

“For instance,” McInerney says, “domestic refrigerators have virtually stopped using HFCs, the vast majority of smaller split system air conditioners have moved away from R410a, and many supermarkets are transitioning their refrigeration systems away from high-GWP refrigerants.”

Australia did start its phase-down earlier than many nations, Brodribb says, but some aspects need greater effort.

Refrigerants Australia Executive Director Dr Greg Picker says most other signatory nations to the Kigali Amendment have chosen three substantial tranches of reductions in high-GWP refrigerant use. Australia started with 80 per cent below the baseline as the initial target, and then every 10 years “tightens the tap” with an 8–10 per cent reduction.

Progress is monitored through six-monthly reports by HFC importers. Aggregated import data is made publicly available at the department’s website.

Picker says that in other countries, the industry gets used to the status quo between phase-downs, then experiences significant disruption when the next step down is implemented.

February–March 2022

Consumption of R404a remains “stubbornly high” with more than 850 tonnes of consumption per annum, he says. The Cold Hard Facts report shows the amount actually consumed within the industry, whereas the Montreal Protocol defines consumption based on import quantities. So, we may look on track by the protocol measure, but domestic supply and demand is holding us back when it comes to R404A.

Feature It is predominantly used in the cold chain for food and commercial refrigeration applications, Brodribb explains. That includes cold rooms, food retail display cases and mostly independent supermarkets. Brodribb says the main driver for the continued use of R404A appears to be price, as there is a significant part of the food retail and cold chain sector that is very cost-conscious. But the cost to the global atmosphere of R404A is significant. It has a GWP of 3,922, which is the highest of any refrigerant commonly used in the economy. It can be substituted with HFC/HFO blends R449A or R448A, which have GWPs of less than 1,400 – almost two thirds less – and most plant and technology currently in use can be retrofitted with these lower-GWP, class 1A refrigerants that are non‑toxic, non-flammable and use the same oils. The difference is cost. Brodribb says the HFO blend costs about $10/kg plus contractor margin for the SME, which in the grand scheme of things, is “not much”. Currently less than 5 per cent of this type of equipment is using the new lower-GWP blends, but the majority of it technically could be, he says. Other applications are further along. Brodribb says small split systems are now making the transition largely to R32, and this constitutes the majority of equipment being imported. A further policy measure of imposing a ban on splits with higher GWPs could be helpful to prevent more R410A going into the refrigerant bank by stopping the tail end of products with that high-GWP refrigerant.

Picker notes it is expensive initially, and it can be more challenging to get equipment serviced due to fewer technicians having the specialised training. Because CO2 is a high-pressure solution, there may also be more breakdowns, but these problems are expected when new technology is first used.

Brodribb also singles out auto air conditioning as a sector that is lagging compared to other industrialised economies. Based on 2020 analysis, about 85 per cent of new cars in Australia still use the high-GWP refrigerant R134a. “Auto could be sped up,” says Brodribb. “There are moves for the first major auto manufacturing players to bite the bullet, so we could see a really rapid switch in about 2025.”

Another hurdle is that in high summer temperatures, CO2 equipment may not deliver an optimal level of energy efficiency, so some asset owners are using HFC/HFOs instead of the R404a in scenarios where high temperatures can be expected and energy efficiency is a top priority.

“What drives future consumption is the bank of product, so we need to limit what goes into the bank.” That could mean prohibitions on new cold chain equipment using R404A, the R134A used in auto air conditioning, and R410A in smaller stationary air conditioning.

Brodribb notes there are parts of the industry where the phase-down is going extremely well. For example, the growing use of natural refrigerants as opposed to synthetics, including the transition to hydrocarbons in small-scale units using less than 494g of refrigerant.

Picker says in Europe, most cars are already using R1234yf and have been for the past six years. But auto manufacturers supplying Australia are “cheap” and are installing the high-GWP R134a instead of the low-GWP R1234yf, even though the cars are designed to use the latter – which would cost around AUD$35 extra per vehicle.

The transition to hydrocarbons in domestic refrigeration is now at around 99 per cent. Commercial refrigeration penetration such as drink fridges is at around 50 per cent low-GWP equipment. And in food retail applications, including independent supermarkets, the transfer to “pretty robust” CO2 trans‑critical technology is going well.

Picker also agrees with Brodribb about the need to reduce the high-GWP R404A. “Another spot where we need to see movement in new equipment is R404a used in commercial cold rooms and commercial refrigeration,” Picker says.

“The technology has advanced over the past five years,” Brodribb says. “And now the engineers have [CO2 applications] sorted in high ambients.

As well as the HFC/HFO alternatives mentioned above, new equipment can use CO2, as large supermarket chains Woolworths and Coles are installing when they build new stores.

“There are some critical cross-over points that will challenge us, but there is generally lots of good stuff going on.”

A COVID SPANNER IN THE WORKS Picker notes the past two years have caused disruption due to the quota-based approach of the phase-down.

As import quotas are reduced for high-GWP refrigerants, expect their prices to rise.

THE DEMAND PICTURE

For example, the car market is unlikely to move until the technology does.

Picker identifies several factors playing into demand for high-GWP refrigerants. One is the pressure rating and flammability rating for most equipment is not suitable for retrofitting alternatives.

“There needs to be more contractor awareness around the different sectors and what those sectors could do,” Hedge says. While larger and smaller applications are both tracking well with the phase-down, Hedge says the middle is where the big challenge lies. Small equipment is benefiting from changes at the manufacturer end in Europe and Asia, where standards have driven a switch to low‑GWP products. The larger applications such as the big supermarket chains should be “given credit for their leadership and vested interest in using natural refrigerants,” Hedge says.

The amount of high-GWP product still allowed in the market should be sufficient to continue to service the existing equipment that requires it for the rest of that plant’s working life, Picker says. Kirby National Sales and Marketing Manager Brett Hedge, M.AIRAH, says the blanket approach of the phase-down may need to become more targeted. Some self-contained applications and small to medium refrigeration applications in particular are “lagging on innovation and initiative”.

STRENGTHENING THE PHASE-DOWN Refrigerants Australia Executive Director Dr Greg Picker says there is a need to incentivise new equipment that has low-GWP refrigerants.

“Policy needs to be set so there are funds for innovation,” Hedge says. “There are currently zero funds for innovation and zero funds being used for downstream awareness.”

“In selected areas the government should put in place GWP limits,” he says. That includes small split systems still using R410A instead of the low‑GWP R32 and car air conditioning.

Policy certainty and support for innovation will encourage some of the large, landmark assets to look to shift to low-GWP refrigerants. Currently, many of our iconic buildings have not, and if they haven’t, Hedge wonders what hope a small business has of making those plans.

Kirby National Sales and Marketing Manager Brett Hedge, M.AIRAH, says there is a need to raise awareness among technicians and tradies about making refrigerant choices based on GWP so they can effectively advise their clients. Many are not thinking about the future availability of specific products when they are giving product advice based on what’s available today.

He says refrigerants should also become part of sustainable and low-carbon building design standards. That would be a lever, Hedge explains, if tools such as Green Star began to recognise low-GWP refrigerants within the rating credits and standards.

“People often go with the path of least resistance with refrigerants,” he says. “And high-GWP product is still available in abundance.”

Picker says training and education also needs to be a priority. Improving the quality and quantity of the available HVAC&R workforce means getting the message across that the sector offers well‑paying jobs and is a highly skilled profession.

Raising consumer awareness would also be helpful so a client like a café owner starts asking questions about what a refrigerant will cost them in 10 or 12 years’ time. Because as Hedge explains, as the supply of high-GWP refrigerants continues to shrink, the cost of them is likely to increase.

“We need more investment in training and education,” Picker says. “Is this the responsibility of the federal government? Maybe not. It is a societal issue, and that should be managed.

“It’s like petrol cars,” he says. “The price is OK now, but in the future a scare will come. The availability constraint [for high-GWP refrigerants] is certain, and availability tends to affect price.”

“However, there is scope for a creative government to launch a huge ‘trades for the future’ package across renewables, trades and building. We also need to be finding ways to better support people already working in the sector.” ■

Good policy leadership would be helpful, he says.

February–March 2022

There were two main problems. First, the quota system has a “use it or lose it” approach, so whatever quantity of high-GWP refrigerants are imported in any calendar year then becomes the maximum amount allowed the following year. Because of global supply‑chain disruptions and demand-side issues in Australia during the pandemic, the amount that physically arrived in the country was not a true reflection of demand or current need. For many businesses, cashflow issues associated with lockdown restrictions and other impacts also meant they could not afford to import additional refrigerant and stockpile until the economy revived again. Picker says the government has been “understanding” and has put in place a provision that if a business imported between 76–100 per cent of its allocated quota, it would be counted as the full 100 per cent. It also allowed capacity for a small amount of overages not to be considered in the 2020 calendar year. Going forward, between 95–100 per cent will also be counted as full quota, Picker says. Another issue relates to the disruption to global shipping – which has seen cargo delayed due to congestion in the North Asia trade nodes – equipment shortages, blank sailings (cancelled transport trips), and disruptions to supply-chain transport links. Goods ordered in expectation they would arrive in 2021 may not arrive until 2022. A new regulation allows those who in “good faith” ordered in 2021, and had every reason to believe it would arrive before December 31, to count them in the 2021 quota, even if they arrive in January 2022. In these cases, there will be no penalty for being over quota. ■ For the middle of the market, one of the push factors that is missing is the life-cycle cost appraisal and cost‑benefit analysis over 15 years or more. Many businesses in this part of the market don’t look or plan that far ahead, so they are not calculating the life-cycle picture, or requesting that information. Hedge says another background issue is a lack of training options available in recent times for trades and technicians. This is particularly in relation to the safety practices required for the use of the natural refrigerants. “Cost and safety are a bit of an over-riding factor around natural refrigerant usage,” says Hedge, “but a full transition to natural refrigerants is possible.”

HVAC&R Skills Workshop Do I need a permit through the ARC to handle and buy R32?

Yes. R32 is controlled under Australia’s Ozone Protection and Synthetic Greenhouse Gas Management legislation. A refrigerant handling licence (RHL) is required to work on systems containing R32. A refrigerant trading authorisation (RTA) is required to acquire, possess and dispose of R32. These are both administered by the Australian Refrigeration Council (ARC). Although R32 has a lower global warming potential compared to other common refrigerants, it is still mandatory to recover this refrigerant from

end of life air conditioning and refrigeration systems or during maintenance on the refrigeration circuit. Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant. Regardless of the licensing provisions, employers have a duty of care to ensure that their workers are appropriately trained and have the necessary equipment to use A2L refrigerants. For additional occupational and work health and safety licensing requirements, check with the relevant state-based licensing authorities.

What equipment do I need to handle R32? Only use equipment rated for use with (A2L or A2) flammable refrigerants. Personal protective equipment should always be worn when handling R32 or any other refrigerant. Due to the flammability and high operating pressures of R32, existing equipment (e.g., manifolds, gauges, vacuum pumps, recovery units) must be checked for compatibility. Any potential sources of ignition from electrical equipment must be eliminated.

HVAC&R Skills Workshop Safety issues to be aware of when handling R32

Australian Standard AS/NZS ISO 817:2016 classifies R32 as A2L lower flammability. Technicians need to take the relevant safety measures for the correct transport, storage and handling of a flammable gas. This includes ensuring that the gas is not exposed to open flames or other ignition sources. Toxic substances like hydrogen fluoride and carbon dioxide are created when R32, like all fluorinated refrigerants, is burnt. Asphyxiation and freeze burns are also a risk. For transportation purposes, R32 is classified as a dangerous goods class 2.1 flammable gas under the Australian Dangerous Goods Code and therefore requires additional handling and storage safeguards compared to class 2.2 non-flammable gases. Safety issues to be aware of: • For installation of split system air conditioners, concentration levels are important, especially with ducted systems. The smallest unventilated room the system serves dictates the maximum refrigerant charge that can be safely installed. • Ducted indoor units pose an additional hazard because the indoor unit is generally in a confined space with only a small amount of room between the indoor unit and the rafters. If a gas leak occurs within the indoor unit the refrigerant can pool and become trapped, reaching flammable concentration levels. • Dry nitrogen should always be used when brazing to displace the oxygen and prevent oxidisation on the inside of the pipework. This procedure is important as it is also required to displace the residual refrigerant and prevent concentration levels conducive to ignition.

Further information Manufacturers and suppliers are required to include additional safety information in the installation and service manuals for air conditioners using a flammable refrigerant. Technicians should follow these instructions. The Flammable Refrigerants Safety Guide developed by the Australian Institute of Refrigeration, Air Conditioning and Heating outlines the occupational health and safety risks associated with refrigeration and air conditioning equipment and systems that use flammable refrigerants. Module 8 covers cylinder handling, storage and transport. See the “More information” section for details on how to access this guide. Please refer to the updated 2018 edition. Check with the relevant state-based WorkSafe agencies and refer to the relevant material safety data sheets available from refrigerant wholesalers for specific safeguards when handling R32.

Training for R32

Suitable trade training in flammable refrigerants is recommended prior to working on systems containing flammable refrigerants. It is a requirement under work health and safety obligations that employers must ensure only competent workers work on air conditioners and other refrigeration systems, particularly those containing flammable refrigerants. Workers must be provided with appropriate information and training on the hazards and safe use of the specific refrigerants to which they could be exposed when performing installation, commissioning, service, repair, maintenance and decommissioning of refrigeration and air conditioning equipment. A national unit of competency is available for A2L refrigerants (including R32) – VU22583 Class A2/A2L Flammable Refrigerants. It sits in the course – 22329 VIC Heating, Ventilation and Air Conditioning Service as an elective. To read more about this unit of competency visit https://training.gov.au/Training/Details/VU22583. There are also the following national units of competency which cover both A2L and A3 refrigerants: • UEERA0007 – Apply safety awareness and legal requirements for flammable refrigerants • UEERA0048 – Install and commission flammable refrigerant air conditioning and refrigeration systems • UEERA0084 – Service and repair self-contained flammable refrigerants air conditioning and refrigeration systems.

refer to the Flammable Refrigerants Safety Guide (2018) online at http://www.pointsbuild. com.au/airah under “managing health and safety risks for flammable refrigerants”. See the “More information” section for details on how to access relevant Australian Standards.

Allowable charge of R32

The allowable charge in an A2L residential or light commercial air conditioning system is specified in Australian Standard AS/NZS 60335.2.40 and takes into consideration variables such as the room floor area, height of the air conditioner, type of air conditioner, characteristics of the particular refrigerant, the level of ventilation and the application of risk mitigation devices such as sensors and alarms. The common room volume calculation of 20 per cent is not applicable for systems operating on R32. Considering the number of variables and the complexity of the required calculations, the Australian Standard mandates that the manufacturer shall perform the calculations and that the installation instruction will clearly show the resulting minimum floor area that the equipment can be installed into under likely installation scenarios.

Where can I buy R32?

R32 is available from most refrigerant wholesalers and stationary air conditioning component suppliers.

Can I convert an existing R410A system to R32?

No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32. R410A systems are not designed to operate using a flammable refrigerant and would require extensive modification and laboratory validation to confirm that the safety level has been increased to a level that satisfies the requirements of international standards set for systems that use R32. It is not just the electrical components that must be compliant with the mandatory safety requirements (i.e., AS/NZS 60335.2.40) for the refrigerant used, it is the whole air conditioner. This includes surface temperatures, operating and installation instructions, markings and warning labels, mechanical strength etc. Anyone doing a conversion or modification takes on the responsibilities of the designer/manufacturer and therefore must certify that the modified product is compliant with all applicable codes and standards. Compliance with AS/NZS 60335.2.40 can only be ascertained by physical testing in a laboratory and AS/NZS 5149.1:2016 has refrigerant charge limit requirements. As a result, it would be difficult for any technician to confirm compliance.

Legal Speak

KEEPING IT CASUAL? A recent High Court decision has forced employers and employees to rethink the rules of casual employment. On August 3, 2021, the WorkPac Pty Ltd v Rossato & Ors case came to a long-awaited decision. Overruling a Federal Court decision, it confirmed that employees engaged on a casual basis as stated by their contracts will not be considered permanent employees, and that obligations are not determined by post-contractual conduct. Put simply, this means that the terms of an employee’s contract will be determinative in defining the employment relationship.

CASE BACKGROUND Mr Rossato claimed he was a permanent employee, relying on the decision of WorkPac v Skene (2018) 264 FCR 536, which held that a casual employee is an employee who has “no firm advance commitment” to the duration of their employment or the days they are to work. Rossato’s claim was that he had been given a firm advance commitment as he received a roster up to a year in advance and ongoing work due to having six contracts. The High Court unanimously decided that the fact Rossato was provided rosters up to a year in advance was not a contractual promise that amounted to a firm advance commitment to work. Also, where there is a written contract containing the terms of the employment relationships, the parties are to adhere to those terms. This decision reinforced the meaning of a “casual employee” in the Fair Work Act 2009 (Cth). The Fair Work Act now provides that an employee is a “casual employee” if:

•

An offer of employment made by the employer to the person is made on the basis that the employer makes no firm commitment to continuing and indefinite work according to an agreed pattern of work of the person

•

The person accepts the offer on that basis

•

The person is an employee as a result of that acceptance.

Businesses are recommended to note these changes to avoid the risk that casual employees will later bring claims against them. Accordingly, it is recommended that employers should have their lawyers review their employment agreements and conditions of employment to ensure compliance with this latest legal development.

WHAT IT MEANS FOR EMPLOYEES

This means that regardless of post-contractual conduct suggesting otherwise, the terms of the employment contract will determine the legal relationship in a comprehensively written contract.

Employees are urged to ensure that they are aware of what is written in the terms of their employment contract, as employers are able to rely on the terms written in their contracts.

WHAT IT MEANS FOR EMPLOYERS

If there is a term or clause that they are concerned about or there are expectations that are not written in their contract, it is important to discuss that before signing.

It is important for employers to ensure that they are clear with the terms stated in employment contracts, as the High Court ruling has shown that what is written in the contract defines the legal relationship of employment.

If they are relying on the employment to be permanent and ongoing, ensure that it is written clearly in the contract.

Employers are able to rely on the written terms of their employment contracts.

The decision may also extend to other terms of the contract, so both employers and employees are recommended to carefully peruse their employment contracts to ensure that the terms within them are concise and unambiguous. ■

It is important to ensure that the terms in casual employment contracts state that the employees are casual, and there is no ambiguity.

GENERAL MANAGER, REFRIGERANT RECLAIM AUSTRALIA How would you describe 2021 for RRA, and the HVAC&R industry in general?

RRA is anticipating a glut of redundant refrigerant

For much of the industry, 2021 was a challenging year, and RRA was no exception. While things in 2021 didn’t go exactly as planned, with lockdowns and travel restrictions stifling some projects, RRA used this time to make important improvements to our operations, and we are now well positioned to resume a new “business as usual” that can better accommodate an increased volume of recovered refrigerants and flammable refrigerant mixtures.

– mainly R410A and R404A – will be returned for destruction We also expect a greater uptake in low-GWP refrigerants used for servicing installed equipment as Australia enters the next step down in the HFC phase-down, effective January 1, 2022. This will see equipment containing traditional high-GWP refrigerants, such as R404A, retrofitted or replaced with lower-GWP alternatives.

Despite the challenges, RRA achieved its best year on record, receiving nearly 580 tonnes of recovered refrigerant back for destruction. The result was no doubt bolstered by the Gas Seeker Initiative, which saw RRA triple the rebate paid to contactors for used and unwanted refrigerant. However, we couldn’t have achieved this without the perseverance and dedication of Australia’s RAC technician and wholesaler network that pushed through during the trying times of 2021.

RRA would love to see companies voluntarily surrender high-GWP products such as R404A or R410A for destruction, so these environmentally harmful gases can’t leak into the environment at any point in the future. While these events may not necessarily be condensed into 2022, we are well prepared to accommodate increased volumes of used, unwanted and redundant recovered refrigerant at any time.

I’d like to thank all involved in helping RRA achieve these tremendous results. What business conditions do you expect to face in 2022?

The one thing that we have learned since COVID-19 is that business needs to be adaptable. I believe RRA is in a fantastic position to adapt to any challenges that 2022 may throw at us.

RRA is anticipating a glut of redundant refrigerant – mainly R410A and R404A – will be returned for destruction as R410A equipment reaches end of life. While some of this product may be reclaimed and re-used, there will be a surplus of recovered R410A, as R32 equipment has steadily replaced R410A over the past few years.

What will be some of the big challenges to the HVAC&R industry in 2022? It’s a great question and one which RRA is seeking the answer to. That’s why we recently launched

Project Ignite. RRA has employed the expertise of an independent research company, Pollinate, to undertake a study aimed to gather information on technician and business owner needs and the biggest challenges faced in RAC jobs. I’ll be better placed to answer this question once Project Ignite concludes early in the new year. What changes and emerging technologies could disrupt the HVAC&R industry in 2022? In recent months there has been a renewed focus on improving end-of-life management of consumer electronics. E-stewardship is about making everyone in the product life-cycle take responsibility for its end‑of-life fate, rather than leaving it for the recyclers. RRA is supportive of the inclusion of spilt system air conditioners, domestic refrigerators and other RAC equipment in this initiative. After all, split system AC accounts for more than 80 per cent of the installed bank of equipment throughout Australia. Through a recent study conducted by RRA into the split AC sector, we found that approximately 945 tonnes of refrigerant is available annually at end of life from this sector alone. This is almost double the total amount of refrigerant recovered and sent back to RRA annually. A coordinated approached between government and industry will be required for such a program to be successful, and to prevent large volumes of environmentally harmful substances being released to atmosphere. What’s in store in 2022? RRA will continue its efforts to understand how we can better serve the industry and to actively assist the industry dispose of used, unwanted and redundant high-GWP refrigerants through targeted campaigns. Watch this space. ■

We need to be constantly evolving because technology changes, legislation changes, and even licence requirements are changing! With changes to refrigerants, the aim for more efficient products, and the move to more electronic-type technology, the one thing that is certain is that there will be new things on offer and the industry needs to move with those changes. ■

Cover Feature DR MICHAEL RIESE, M.AIRAH

MANAGER – DEFENCE BUSINESS, RESEARCH AND DEVELOPMENT, COLD LOGIC How would you describe 2021 for Cold Logic, and the HVAC&R industry in general?

Our clients and the general public are placing more value on locally made

It was a year full of challenges for a number of reasons. With offices in both South Australia and Victoria, the COVID restrictions were very different in both states. We saw multiple state-wide lockdowns in Victoria and full travel bans for Victorians into South Australia. This made work very hard, especially for our border corridor clients that still relied on our services into Victoria from our South Australian operations. Through a thorough and good preventative maintenance regime executed at those clients’ sites over many years, we were able to reduce our visits to a bare minimum when required without causing any breakdowns.

product and produce What will be some of the big challenges to the HVAC&R industry in 2022? Lead times and pricing for specialist components is a major stumbling block that started to form in 2021 and will only continue to grow in 2022. Also, there is now a larger skills shortage than ever before both in the trades and professional area as recruitment from overseas has been cut off for most of 2020 and all of 2021. This makes it harder to maintain business growth and continuity, especially with existing staff across the sector retiring or simply leaving altogether.

Overall though, our year was very busy. New opportunities opened up, especially in areas of South Australia that have been traditionally serviced by Victorian or New South Wales service providers that were now no longer able to attend site or address and breakdowns in a timely manner. We believe this development is here to stay, and highlights to clients that cheap is definitely not the winning formula if the provider is not able to attend the site.

What business conditions do you expect to face in 2022? It will be a very different year with Australia as a country and individual states opening borders to varying degrees. This has the potential to raise COVID-19 cases in areas where it has previously not been seen in large numbers.

With a number of essential services clients in the food and beverage and pharmaceutical industry sectors now requiring double vaccination to enter sites, business may become a tightrope dance. Only well-prepared and organised companies will be able to succeed and weather the storm. Many companies are making investments in Australia that include new refrigeration equipment. This is certainly a good sign for business, but has to be seen in the light of longer lead times for goods produced overseas and increasing prices, completely changing the dynamic around project financing and viability. What is business confidence like as we enter 2022? It is improving. Our clients and the general public are placing more value on locally made product and produce, as supply-chain restraints become harder and harder to ignore. This leads to further investments by producers creating a larger trickle-down effect and more jobs across the country. What changes and emerging technologies could disrupt the HVAC&R industry in 2022? The biggest change will be the supply-chain shortages that we have not experienced for a long time. Shipping costs are increasing, and Australian companies are competing with overseas buyers in much stronger markets such as North America and Europe. Those who have great suppliers and trusted supply chains will be at the forefront of the post-COVID recovery, with new and different opportunities not seen for decades. ■

STEVE SMITH

EDUCATION RELATIONSHIP MANAGER, SUPERIOR TRAINING CENTRE (STC) How would you describe 2021 for TAFEs and RTOs?

administrative priority over the past two decades but would now appear to be biting back.

The two biggest issues

Every TAFE RTO across the nation reported a large spike in apprentice enrolments at the start of 2021, presumably in response to the pandemic incentive programs offered by state and federal governments. This was seen as very positive news given the decline in apprenticeship engagement over the past 10 years.

… are the diminishing pool of qualified and competent technicians and escalating wages employers relaying the concerns of their apprentices that the “off-job” component of the training has been of a lower standard than previous years.

A recent report released by the national body responsible for collecting and analysing VET statistics (NCVER) shows that completion rates for electrotechnology apprentices decreased from 65.6 per cent in 2019 to 59.7 per cent in 2020, with the two most common reasons for non-completion being “I lost my job” and “I didn’t get on with my boss or other people at work”. The completions report for 2021 is due out in early 2022 but is not expected to show a reversal in the declining trend, given the high number of contract cancellations submitted throughout the year.

What will be some of the big challenges to the HVAC&R industry in 2022? The two biggest issues I’m hearing from employers are the diminishing pool of qualified and competent technicians and escalating wages. These naturally go hand in hand. This trend is occurring across all trade areas and will likely continue unless the apprenticeship mechanism is somehow morphed into a more appealing and valued career opportunity for citizens within our communities.

The extensive lockdowns imposed at the height of the pandemic brought about another unanticipated issue for RTOs across the nation. Students were not able to attend normal face-to-face classes, triggering a scramble to online delivery for the theory content. Colleges report they are still catching up with the hands-on practical component of the course. This has been supported by 24

HVAC&R News

The challenges for RTOs will be:

•

The lack of skilled technicians applying for teaching positions. The impact is a rapidly ageing teacher cohort that is overworked and highly stressed.

•

The high level of casualisation in the “front-ofhouse” workforce (the teachers). This has been an February–March 2022

•

Need for teachers to maintain industry currency. This is a persistent problem for RTOs as technology changes and course content increases. A new version of the trade course is due for transition in the last term of 2022, adding to the currency issue and administrative stresses.

What is business confidence like as we enter 2022? Demand for refrigeration and air conditioning installation, fault finding and maintenance work appears to have increased – particularly in the residential air conditioning sector and predominately driven by the shift to working from home. This would normally inspire increased confidence; however, the shortage of skilled technicians is making it difficult for companies to meet market demands, further fuelling wage increases and overall operating overheads for employers. What changes and emerging technologies could disrupt the HVAC&R industry in 2022? The technology advances made in carbon dioxide (CO2) refrigerant systems over the past five years have been rapid and inspiring, particularly in the supermarket sector. I expect we’ll see further expansion in this arena, together with “plugin” self-contained CO2 systems for the smaller commercial market. We will also witness an increase in the use of the new range of synthetic HFO refrigerants, predominately in the commercial air conditioning sector. ■

FOCUS ON FIRE IN NSW

The company says the world must move from a “best endeavours” carbon-reduction process to a definitive and transparently accounted for elimination approach.

The NSW government has released a report that provides recommendations on how to improve fire safety in new and existing buildings.

“It is important that A.G. Coombs as a significant provider in the Australian property and building construction industry’s supply chain has a strong process in place to be part of this transition,” says A.G. Coombs Group Managing Director Russell Telford, “including a clear commitment to a net zero operating position.”

The project was commissioned by the Office of the Building Commissioner to draw upon specialist industry expertise to identify practical measures the NSW government could take to help improve fire safety in class 2 residential buildings.

Since 2005, A.G. Coombs has operated an environmental program, with two objectives: reduce the environmental impacts of its operations, and assist customers and clients to achieve the same. ■

“While there have been a range of reforms to improve fire safety,” the report reads, “there remains room for improvement. Serious defects in fire safety systems are the second most common defect identified by inspections of class 2 buildings undertaken under Fair Trading’s occupation certificate (OC) audit program, arising in around 46 per cent of buildings. Also, recently published research found serious fire-related defects were in around 14 per cent of strata buildings completed in the last six years.”

The A.G. Coombs Group has committed to a clear net zero goal: Scope 1 and Scope 2 operational emissions by 2030. The building services specialist will work with its value chain, industry partners and customers to achieve net zero Scope 3 emissions by 2040.

According to the company, the location offers additional warehouse space to help expand RectorSeal’s current product offering to customers, and the warehouse will be fully staffed “to ensure operational excellence with regard to customer service and product availability”. “Our team is enthusiastic about the new warehouse location, which will support our strategic goal of increasing inventory on hand while decreasing shipping times,” says RectorSeal Australia General Manager Craig Bicket. “With our own dedicated space, we will be able to manage a greater level of inventory to serve our customers’ needs more efficiently.” Bicket and other key RectorSeal staff members will relocate to Queensland as part of the new warehouse move.

“The prestigious awards continue the decade-long tradition of recognising and rewarding outstanding contributions within Australia’s HVAC, refrigeration and building services industry.”

“I look forward to meeting our current and new customers to show them our new facility,” says Bicket. “We expect these impressive enhancements we’ve made will offer even higher levels of customer service along with a broader product offering.”

A panel of industry experts will evaluate nominations based on criteria such as leadership, sustainability, performance and innovation.

“Climate change is the most critical challenge facing the world today,” A.G. Coombs says. “Through their construction and operation, buildings are responsible for nearly 40 per cent of annual global CO2 emissions. The A.G. Coombs Group is committed to minimising its emissions impact.”

“If you know a person, business or product that through their endeavours deserve to be recognised by the industry, then nominate for an ARBS 2022 Industry Award,” says ARBS.

RAC APPRENTICE NAMED TOP TRADIE

TAFE Queensland refrigeration and air conditioning apprentice Natasha Kirchner has been chosen as the Construction Skills Queensland Tradeswoman of the Year at the National Association of Women in Construction (NAWIC) Awards in Brisbane. Held annually, the NAWIC Awards showcase the achievements and industry advancements of women, men and organisations in the construction industry. Kirchner was recognised for her dedication to building a successful career in HVAC&R, along with her passion for being a positive role model for other females wanting to pursue a trade career. Before switching to RAC, Kirchner worked in hospitality, but was unhappy with her career direction. One day she helped a friend install an aircon unit at his parents’ house, and took an instant interest in how the system worked. “At the end of the day, I was captivated,” says Kirchner. “I have always been a hands-on learner and love being involved in anything that gets my hands dirty, but never connected this with a trade.”

As the winner of the award, Kirchner will have the opportunity to work with NAWIC over the next 12 months as a volunteer Tradie Ambassador. ■

technicians, numbering more than 115,000 today, have reduced Australia’s emissions of ozone depleting gasses by more than 25 mega tonnes. “Businesses across all industries will introduce practices that reduce environmental damage as governments adopt a risk management approach to cutting GHG emissions to reduce harm to others and the environment.”

TASTING NOTES

Late last year the Tasmanian division of AIRAH organised a site visit to the Overland Brewery and Distillery – a brand-new boutique brewery, distillery, cellar door and bar in North Hobart.

LAWN RANGER

Like having a neat patch of lawn but not so crazy about pushing the old Victa two-stroke around (and around and around)? A robot lawnmower might be the solution you didn’t know you needed. Yes, you will have to spend some time setting up the perimeter for the area that requires attention, and establish a charging station.

A robot lawnmower can provide immaculate turf – minus too much of your elbow grease.

(And no, we don’t think the lawnmower will achieve self-awareness come Judgement Day and start telling you what to do.) There are plenty of advantages to using a robot lawnmower. It trims grass to a high standard without noise or petrol odours, mulches as it cuts, and is pet and child proof. “It’s quiet, it doesn’t smell, it’s not even that large an object milling about,” says the Gadgetguy website. “You can relax on the deck or patio as your robot lawnmower trundles around doing the work you used to have to give up your Saturday mornings to do. What could be better than that?” PC Mag rates the Worx Landroid M 20V Cordless Robotic Lawn Mower as the pick of the trimming bunch for overall performance and versatility. “The Worx Landroid M 20V is a relatively affordable smart robotic lawnmower with GPS and wi-fi,” says PC Mag’s John R Delaney, “so you can control it with your phone no matter where you are.” RRP is about $1,600.

JUST HANGING OUT

Mark found this gem in his sister-in-law’s new rental property on the Gold Coast. “It overhangs the wall,” he says, “and you can see daylight around the unit!” Graham says: One of the challenges of installing split systems is finding an appropriate inside wall to hang it off. Not always easy.

GOING BUSH

SOLDER ON

This job, on a roof in Launceston, calls for a dual trade: fridgie and arborist! Thanks to Chris for the photo.

Jayden was on a job when he found this condensation pump hanging by four sticks of silver solder. His team replaced it with a safety tray set-up.

Graham says: It appears a pair of secateurs should be included in the toolbox. The lack of maintenance is obvious. How many times does a service call simply require cleaning rubbish away from a condenser so that it can “breathe”?

Graham says: Might have been a temporary fix – sometimes you just don’t get back to finish the task!

DIY DUCTWORK

DOUBLE TROUBLE

James was working on a job when he spotted this beauty at the property next door.

An office partition was built across this system in Maitland, NSW. Graham says: How would you even clean the filter? Unbelievable!

Graham says: They’ve installed the units so they are blowing into the house wall, then to top it off they haven’t used any mounting blocks to reduce noise and vibration.
