Ed’s letter

MONEY TALKS – DO YOU LISTEN? When I first decided to get into publishing, a successful journalist mate told me a joke: What’s the difference between a journo and a pizza? A pizza can feed a family of four. I didn’t find it very funny at the time. But in the 15 or so years since – over which time I’ve formed a family of four, and seen the print publishing industry in Australia recede even faster than my hairline – it has kept coming back to me. Each time it gives me a little chuckle. There is a shade of “if you don’t laugh you’ll cry” about it, but still, it’s funny. Luckily, it’s never been the dollars that have attracted me to my job. Before I moved into magazines I was working in IT, and making good money.

Even back then a lot of my work involved writing, but it was mostly user manuals, which (surprise surprise) no one ever read.

and other trades. And for some, it’s not all about the dollars anyway.

For me, communicating with a real audience was the drawcard. And despite the lower salaries over the years, I’d make the same career move if I had my time over again. Actually, I’d probably make it sooner.

So our feature also looks at some of the other things that could attract people to the trade: the variety of the work, the fact that it is many trades in one, the strong demand for workers, and the technology you get exposed to.

So this month’s cover story, which is all about salaries in HVAC&R, is an interesting one.

Seems to me there are lots of things we should be shouting about.

On one hand we are trying hard to find ways of attracting more and better talent to our industry. If fridgies are – as the research suggests – the best‑paid trades in Australia, surely that is something we should be shouting about.

The next question is how we do that – not just in magazines like this one being read within the industry, but also with the general public. ■ @AIRAHnews

False alarms given the shaft

Gas Alarm Systems has released a new, more economical gas alarm to start the new year. The company points out that a large number of projects are now going for VRV/VRF systems over traditional chilled and hot-water systems.

“Most remarkable is the re-design of the inner construction. By using innovative PPSU polymer material the resistance of the valve to scaling and clogging has been considerably improved compared to any other HVAC control valve. Intensive testing proofs continued stability of the flow characteristics and accurate control performance.”

“This means refrigerant gas is travelling directly to the rooms,” says the company. “If the room is small and the condenser is large, a significant dump of refrigerant gas could take place if there is a leak in the system. “Traditionally, low-cost semiconductor-based sensors are used for refrigerant leak-detection applications. While these are OK in plant-room-type installations, in indoor spaces these are a very big no.

Danfoss says the pressure class has been increased from PN16 to PN25 while the required differential pressure continues to be just 16kPa.

“Constant false alarms from various gases are always a risk in indoor spaces. Smells from strong perfumes, spray and wipe cleaners, aerosols, VOCs from the fresh paint and furniture can all cause false alarms. This is the reason semiconductor sensors are to be avoided at all costs.

Go to gasalarm.com.au ■

Reliable and easy to use

“The adjustable flow rate of the AB-QM 4.0 valves has been significantly increased, for example from maximum 450 to 600 L/h with DN15, allowing bigger terminal unit capacities to be controlled by smaller dimension valves,” Danfoss says. “The minimum flow pre-setting has been reduced from 20 per cent previously, to just 10 per cent now. Alternatively, the valves are also available as high-flow or low-flow versions.” Go to www.danfoss.com/en-au ■

“Our range of NDIR sensors offer local, on-the-spot calibration, so there is no need to send the sensors back to the manufacturer, like the other brands.”

“The unique 100 per cent valve authority, achieved by a built-in differential pressure controller, remains unchanged,” Danfoss says. “This ensures the accurate control performance of the valves. Several significant changes and improvements have been implemented, making it a whole new valve rather than an upgrade.

Konsider Kingspan K-Clad

Kingspan Insulated Panels has introduced K-Clad, which it describes as a viable alternative to the traditional construction methods of non-Section J buildings.

The flexible BACnet Virtual Private Network (B/VPN) solution is designed to simplify IT management and improve data communications security, while also being scalable and affordable.

“K-Clad is a high-performing insulated metal roof system, with proven results that demonstrate it outperforms traditional construction methods in terms of speed of build, thermal performance, air tightness, weather tightness and condensation control,” Kingspan says. “All in a single component that provides a finished metal internal ceiling.

“This easy-to-use software does not require additional routers or controllers to deploy and permits multiple separate VLAN configuration,” says Reliable Controls. “Save time and money by deploying and managing your own BACnet secure network.”

“Kingspan K-Clad is a superior alternative to traditional built up systems, ideally suited for large-scale logistics and distribution buildings, as well as temperature-sensitive environments such as cold storage and agricultural facilities.”

RC-RemoteAccess 3.5 is now web-based. It allows users to update B/VPN settings on connected clients in the RC-RemoteAccess interface rather than configuring each one locally.

Kingspan says the Australian climate means that buildings are more often exposed to direct sunlight year-round. This impacts the thermal performance of roof structures as well as the indoor environment and level of comfort for occupants.

The web-based interface allows users to configure and update B/VPN security certificates.

“Thermal modelling shows that, when compared to a traditional built up roof, K-Clad offers a measurable 40 per cent reduction in heat gain, resulting in a temperature decrease of more than 4.5°C between the two tested roof systems,” the firm says. “This significant reduction in temperature can directly improve the comfort levels of building occupants.”

Reliable Controls has released RC-RemoteAccess 3.5.

One or more B/VPNs can be migrated with their connected clients to a new RC-RemoteAccess server in a single operation, and the port and security certificate can be changed as part of the migration.

Go to www.kingspan.com/au/en-au ■

Users can also configure a separate instance of RC‑RemoteAccess as a redundant Failover server. If the Primary server is unavailable, B/VPN connections are routed to and maintained through the secondary Failover server. This server redundancy helps to ensure the reliability of B/VPN connections. “Securing your BACnet connection from cyber threats has never been easier,” says Reliable Controls. Go to www.reliablecontrols.com ■

Danfoss control valves

Danfoss has expanded the product range of its pressure independent AB-QM balancing and control valves for heating and cooling systems. The new Danfoss AB-QM 4.0 valves are designed in sizes from DN15 to 32, and add new features and improved specifications of the well-known AB-QM series. 6

Yellow, oh yeah!

Because it’s the oil that does the work in a vacuum pump, a debate has raged for years as to what the ideal oil capacity should be.

The common and logical point has been that the larger the volume the better; the more oil, the more work can be done between changes, and the less wear and tear on the pump due to oil contamination and suspended particulates. “Yellow Jacket has long held this view until a program run by its R&D department discovered that there is a definite point where more oil doesn’t lead to less wear and tear or more efficient and rapid evacuation,” the firm says. “However, too small a volume of oil leads to increased wear and tear, gallery blockages and reduced pump performance. Yellow Jacket subsequently found an optimal volume that will produce ideal pump performance.”

Toolshed Informed by this research, the Yellow Jacket range of pumps have all had a reduction in oil volume.

“This new range of optimised-oil-volume pumps have the same part number as before,” Yellow Jacket says, “but are recognisable by the new shape, sight glass and shoulder carry strap.”

Ultimate integration

Price Industries’ Ultrasuite system combines hospital-grade LED lighting with precision-equalised laminar airflow diffusers to eliminate the traditional “light ring”, and open valuable ceiling space for surgical equipment.

Radic8’s killer tech

According to Radic8, new viruses communicated through close human-to-human proximity and indoor pollutants and contaminants have driven demand for air purifiers.

“Incorporating LED lighting directly within each laminar flow diffuser allows lighting to be located directly above the surgical table, improving visibility and reducing shadows within the surgical zone,” the firm says.

“Radic8’s air purifiers and sterilisers for both home and commercial use have been proven to trap and destroy 99.9999 per cent of viruses, including the cold virus, flu virus, the SARS virus and even a previous coronavirus,” the firm says. “Tests were also conducted on the polio virus, which proved Radic8’s Viruskiller inactivates those viruses with 99.99 per cent efficiency.

“Flexible dimming control and optional green lighting facilitate improved visibility of flat-panel displays for non-invasive surgeries by enhancing images and eliminating the glare that traditional overhead white lights cast on monitors.

“The Ultrasuite ships in large, factory-assembled sections, and leverages quick-connect wiring and a … low-profile common plenum to significantly reduce the number of inlets and ductwork – and therefore installation time – required. LED drivers are housed in a remotely mounted control enclosure, providing easy access for maintenance and replacement.

“Medical centres, doctors’ offices and hospitals are filled with people who may be potentially contaminated and contagious or have compromised immune systems,” the firm says. “HEPA filters often operate well below their theoretical efficacy level even in places like hospitals. They do not have an ‘absolute’ solution to airborne contamination removal.

“The Ultrasuite is built to meet all ASHRAE 170 and NFPA 90A requirements, and addresses several UL listing categories.”

“A common misconception is that HEPA filters catch all air‑polluting pathogens and contaminants, when in fact the

THE ULTIMATE FRIDGIE BEER?

CAMOUFLAGED CONDENSERS

San Diego-based craft brewery Ballast Point is using condensate from air conditioning systems to make beer.

Daikin UK has come up with a new concept for home-owners who want to “hide” their outdoor air conditioning units: photographic wrapping.

Ballast Point has teamed up with San Diego International Airport to use waste water for the new SAN Test Pilot beer. The airport has been collecting the condensate from the AC units on jet bridges for several years as part of its conservation efforts, capturing about 375,000 litres per year. Previously this had only been used for cleaning, and for the facility’s cooling towers. Now, people are paying for the pleasure of drinking it!

The service allows a unit to be merged with its background by wrapping it in a high‑quality vinyl film based on a photograph provided by the customer. Each panel is removed, wrapped and carefully replaced. The unit is then delivered to site. The service is covered by warranty, and it does not interfere with servicing. Daikin says the wrap also prevents abrasion, extends colour fastness, and offers easier handling.

“Through the years, our R&D brewery has experimented with water reclamation as part of our commitment to sustainability,” says Aaron Justus, Ballast Point’s director of research and development.

Prices range from £589 (Au$1,143) for a single-fan condenser to £1,097 (Au$2,129) for a VRV type.

We can certainly drink to that. Although be warned, at 5.8 per cent alcohol, the Test Pilot will get you flying pretty quickly. ■

At the moment, Daikin Australia has not announced plans to offer the service here, but it could prove popular based on the number of photos we receive of condensers in boxes! ■

INDIA

AC MARKET HEATING UP

SET AND FORGET

Brazil is experiencing strong sales for air conditioning units, partly due to record temperatures during 2019. According to the Japan Air Conditioning, Heating & Refrigeration News (JARN), the year-on-year growth rate for the first 10 months of last year was 20 per cent, and market demand was expected to exceed 3.5 million units for the whole year. The high demand applied not only to single split systems, but also to multi-split systems, which increased by 9.4 per cent. The figures mark a major recovery from the slump in 2016, when the market dropped by 34.6 per cent. Now, local sales staff are predicting that the national market for single-split units should reach six to seven million. The market is also becoming more tightly regulated. New rules on energy efficiency and a new energy-saving standard were introduced in 2019. ■

The Indian government has announced that 24°C will be the new default temperature for air conditioners (AC). This includes all air conditioners that are labelled under the Bureau of Energy Efficiency (BEE)-star program. The default setting is the setting at which a machine comes from the factory. Apparently, very few people in India adjust their AC settings – most let it run on the default. This is the reasoning behind changing the default setting, although users are still able to change the settings as needed. India’s Ministry of Power estimates that by increasing the temperature of a room by 1°C, about 6 per cent of electricity is also saved. The standard room temperature is set to 20–21°C, so this solution will save approximately 24 per cent of electricity. There is no similar rule for default air conditioner settings in Australia. ■

You’ll find plenty of accommodation, food and drink options, and nightlife if you are so inclined.

“This has never happened this early before.”

BIGGER IS BETTER

Not only have 350 exhibitors already committed to ARBS 2020, long-term exhibitors such as Daikin Australia, Beijer Ref Australia (Kirby), Temperzone, Airefrig Australia, Mitsubishi Electric Australia and Panasonic have all opted for larger and more impressive stands to display their product ranges.

After breaking attendance records when it finally returned to Sydney in 2018, ARBS 2020 will surpass all previous size records for the event in Melbourne. Due to the number of exhibitors keen to get their products and services in front of industry professionals, the exhibition floor area at MCEC has been extended to cover a whopping 18,000m², making this the largest ARBS ever in Melbourne.

According to ARBS organisers, exhibitors are going all out to attract visitors to their spaces. Larger and more visually dynamic stand designs are expected to be a key feature of this year’s exhibition.

Set alongside the ARBS 2020 main exhibitor hall, IBTech@ARBS is a precinct dedicated to the exploration of the very latest in intelligent building technologies and solutions. Building on its debut at the Sydney exhibition in 2018, this year’s IBTech@ARBS precinct will showcase the innovation driving new product development and solutions for digitised buildings. But it’s not just for building owners and designers. Anyone working on building services systems found in modern buildings will find the precinct to be an educational wonderland. Recent advances in technology that deliver greater integration and interoperability between key systems will be on show for visitors to engage with and explore. According to Jon Clarke, M.AIRAH, head of smart building technology delivery at Dexus, technology is changing how buildings are both constructed and managed. “There is no other exhibition in Australia like this,” he says. “It really is the perfect spring-board for anyone in the industry who is embracing the digitisation of buildings.”

Running concurrently with the exhibition, the Speaker Series is designed to connect you to what matters most. Alongside some broad-based discussions on topics such as NABERS Energy, there is plenty that is both practical and applicable to HVAC&R technicians and others working at the coalface. For instance, there’ll be a presentation on the decommissioning of existing HFC based aircooled refrigeration plants and replacement with NH3 DX‑based solutions. Then there’s the topic of why seismic restraint of HVAC is required. No doubt the aftermath of the 2011 Christchurch earthquake will serve as an example (see HVAC&R Nation July 2017). Another presentation will reveal how artificial intelligence is optimising HVAC&R systems by generating predictions of system load and resources. And the much-anticipated update of Cold Hard Facts by Michael McCann and Peter Brodribb, M.AIRAH, of the Expert Group will also be presented at the ARBS 2020 Speaker Series. This will shine a spotlight on the state of play in the HVAC&R sector with particular emphasis on the annual rates of change in the adoption of new technology and refrigerants.

Feature A DECADE OF AWARDS

In 2018, Tony Squires was the Awards MC. This year it will be actor Shane Jacobson.

A key event of every ARBS exhibition for the past 10 years has been the ARBS Industry Awards. The awards officially launched in 2010 in Melbourne with the purpose of honouring and rewarding talent within the Australian industry. Over the years, the ARBS Industry Awards have grown to become some of the industry’s most sought-after gongs. One of the winners at that inaugural awards dinner was tech architect Nirosha Munasinghe, who was presented with the Young Achiever Award for his involvement in developing open system controls products for the HVAC market. Reflecting on his win almost a decade later, Munasinghe says it provided a launch pad for his career. “Winning this award was a great honour to me and really catapulted my career,” he says. “We were a small company back then – a small start-up in Melbourne. It gave presence to our company and we were able to establish a distribution network around Australia.” This year, there’ll be a new group of young achievers to celebrate, as well as five other categories: product excellence, software excellence, project excellence, outstanding maintenance and service, and industry education and training.

IN THE POO

Dung good – the Bubas bison dung beetle.

A Western Australian farmer is using dung beetles to address climate change. Based at Marron Brook Farm in Manjimup, 300km south of Perth, farmer Doug Pow is pioneering the use of biochar as a way of sequestering carbon. Instead of relying on intensive machinery, Pow is turning to the winter-active exotic dung beetle, Bubas bison, to fertilise previously inaccessible hill slopes.

He has developed a strategy that encourages the dung beetle to bury biochar-infused manure deep within the soil profile. “When we first bought this farm, I noticed active dung beetles burying virtually every dung pat down as deep as 600mm into the ground,” Pow says. He also attended a talk on biochar, which explained the effectiveness of using GPS-controlled grain-farmingseeding equipment to put charcoal into the ground – and then using the same equipment to plant the seed of the next grain crop over the char. According to the presentation, this increased productivity. Pow began wondering how he could put the system into effect in a place like Manjimup – “where we grow horticulture crops, we grow tree crops, where we have big, high hills and narrow gates and we can’t pull 100m-wide equipment up mountainsides.”

Doug Pow (left) received an Innovation in Land Management Award from WA Landcare chair Keith Bradby.

He attempted to feed some char to his cattle in the hope that when it fell out the other end the beetles

would bury the dung while also placing the char into the ground. The experiment worked. “The soil has become more fertile,” says Pow. “It’s releasing the phosphorous that’s been locked up in the soil back up to the surface. That has a big advantage.” Research into the use of biochar as a feed additive indicates it can promote more efficient digestion in ruminant livestock, and reduce the methane they produce. So as well as sequestering carbon, it is lowering emissions. Another benefit is a marked reduction in odour. Pow will represent WA while competing for the Australian Government Innovation in Agriculture Land Management Award at the National Landcare Awards later this year.. ■

CORROSION AND ASSET PROTECTION

■ What? A guide to the impacts of corrosion on HVAC&R equipment and strategies to prevent it.

■ Who? Relevant for mechanical contractors, consultants, engineers, building designers, sustainability/energy efficiency advisers, facility managers and building owners.

Corrosion is a huge contributor to unnecessary energy and efficiency loss. It will cause a loss in cooling performance, reduced indoor air quality, reduced reliability, reduced energy efficiency and a reduction in service life. These issues will cause such things as discomfort and health risks to building occupiers, higher running costs, higher capital costs and more CO2. But there are ways to limit or prevent this corrosion from occurring. This Skills Workshop provides a step-by-step explanation and analysis of how HVAC&R equipment is affected by corrosion in heat exchanger coils. It looks at how this impacts on efficiency and how it can be prevented in new units or stopped in existing units.

According to the CSIRO, HVAC systems in buildings account for approximately 40–50 per cent of building energy use and contribute to 34.7 megatonnes of carbon dioxide emissions every year. With electricity prices continuing to rise per year and with building energy contributing to Australia’s greenhouse gas emissions, HVAC&R energy efficiency is a major economic and environmental issue, even when not considering the increase in building construction and the expansion of building footprints that we currently see in Australia.

Heat exchanger geometry Air-cooled heat exchangers consist of fins mounted on tubes to expand the heat-exchanging surface. Tubes and fins can be made of several metals like steel, copper, aluminium and stainless steel.

Louvred fins

The heat exchangers, also called coils, may have various dimensions depending on the application. Most heat exchangers are made of copper tubes and aluminium fins. This is because aluminium is easy to process, light and relatively corrosion resistant. Coil manufacturers use different fin forms to adjust the coil to the demands. The simplest form is the straight fin, a flat fin with only minor waves. More complicated is the louvred fin. This fin is perforated to create turbulence of air in the coil. This will increase the capacity of the coil. A coil with this fin type will be much more vulnerable because of the thin aluminium louvres. The louvred fins have an air filtering effect and will be exposed to more pollution. Another option for creating more heat exchange capacity is a wavy fin. The waves will force the air to bounce against the aluminium. See Figure 1.

Table 1

Corrosion of HVAC equipment With air-cooled systems, oxidation of the heat exchangers is a major problem. Aluminium is proven to be one of the most suitable materials for this kind of equipment. The advantages of aluminium are:

A good solution would be aluminium-aluminium. Although this type of coil is becoming more and more popular, some reasons why manufacturers are not using aluminium-aluminium in general yet are: • Tubes made out of aluminium are difficult to weld • The tubes would be damaged more easily because aluminium is softer than copper

• Lightweight metal • Easy to shape

• It is easier to repair copper than it is to repair aluminium.

• Good heat transfer • Cheap. The corrosion resistance of aluminium should be an advantage as well; unfortunately, this is not the case. Aluminium forms an oxide film as soon as it is exposed to air. This action is damaging in that it reflects the tendency of the metal to return to its natural oxidation state. If the oxidation layer were evenly spread, it would protect the metal from corrosion. However, the oxidation layer is patchy, and because of the humidity and atmospheric pollution the process of oxidation or corrosion may accelerate here.

Sources and effects of HVAC corrosion HVAC corrosion is a widespread problem. Australia’s population is concentrated in industrialised, urban, coastal strips and agricultural regions. All these areas contain sources of corrosion on HVAC equipment. Salt and humidity in coastal regions, sulphur oxides, nitrous oxides, hydrocarbons, chlorides, ammonia, electrolytes and contaminated dust all contribute to corrosion.

Another problem concerning air-cooled systems is the construction of aluminium heat exchangers.

Examples of sources are aluminium production plants, fertiliser production, petroleum and chemical production, mining and metallurgy, power generation, paper and pulp mills, sewage treatment plants, steel production, swimming pools and farms.

Most aluminium heat exchangers use copper pipes. When two different metals in a conducting liquid are in direct contact with each other, corrosion of the least noble metal may be the result. The parts closest to the noble metal will be particularly affected.

Environmental corrosion of the fin surfaces and galvanic corrosion at the tube‑fin breaks down this mechanism, which reduces maximum cooling capacity and energy efficiency as the refrigerant condensing temperature is raised to recover cooling performance.

This corrosion depends on:

Table 1 shows a case study of two identical chillers after four years of operation – one untreated, the other treated with a sprayed-on protective coating.

• The potential difference between the two metals • The relationship between the two metals; the larger the cathode surface (the noble metal) compared to the anode surface (the base metal), the more corroded the latter will be

Corrosion of the copper pipes and headers (manifolds) can create pinhole leaks. Formicary corrosion caused by organic acids is a common cause of this type of failure. See Figure 2.

• The conductivity of the solvent

Soldered joints are particularly vulnerable to corrosion by sulphurous gases.

• The presence of oxygen.

Preventing coil corrosion

Copper tube section – formicary corrosion caused by acetic acid Outer surface

There are two ways to prevent HVAC corrosion. One is through materials selection to suit particular environments, the other is through protective coatings. Mono-metal coils such as copper tube and fin or aluminium tube and fin will avoid galvanic corrosion but do not provide complete protection. For this method to be effective, expensive air testing and environmental assessments would be required to provide the best advice on what construction would be best suited for a particular environment. A protective coating is the most readily available and most frequently applied protection measure. Protective coatings for HVAC can be classified in two separate areas: pre-coat (applied prior to coil assembly) and post-coat (applied after coil assembly). Most manufacturers offer an epoxy pre-coat applied to the aluminium fin as the lowest cost option for improving the corrosion resistance of bare metal. Post-coatings are the alternative to pre-coats. So, what do we need to consider when looking for corrosion prevention options for HVAC equipment? Epoxy pre-coats generally have a low resistance (1,000 hours) to prolonged exposure to salt and acid spray. A polyurethane post-coat will protect for in excess of 11,000 hours.

Figure 2 16

HVAC&R Nation

www.airah.org.au/nation

March 2020

HVAC&R Skills Workshop Pre-coats only protect the aluminium fin, not the tubes or headers. After the fin is pre-coated, it is cut to size and holes punched in them for fitment to the copper tubes. This cutting exposes the aluminium which then comes into contact with the copper tubes; the beginning of the galvanic corrosion process. Polyurethane post-coat will cover all surfaces and joints of the fins and tubes.

6 years – city centre

Due to epoxy pre-coat’s low thermal conductivity, it creates an insulation layer at the critical fin-tube junction when fins are formed, and coil is assembled. This can create a capacity loss of up to 15 per cent. Some post-coats contain an aluminium pigment that boosts thermal conductivity. When combined with a low 25-micron dry film thickness (DFT), this can minimise thermal and pressure losses. Capacity losses with this type of coating are 0–3 per cent. With age and exposure to the elements, epoxy pre-coats lose adhesion and have a lower mechanical resistance. The polyurethane post-coat has excellent adhesion to most metals, in particular aluminium and copper, plus have the added benefit of excellent UV and chemical resistance.

<7 years – coastal

The post-coat treatment can be applied in the workshop or onsite and is maintainable, repairable and cleanable. Pre-coats are generally applied with no further ability to maintain or service onsite.

Conclusion HVAC&R efficiency loss accounts for a significant proportion of Australia’s energy consumption, business costs and CO2 emissions. Asset owners and managers are now even more aware of this, plus the high maintenance and replacement costs, and are looking for alternatives to prolong the life of their equipment.

7 years – suburban

Corrosion of heat exchanger coils is a widespread problem and one that adversely impacts the performance and energy efficiency of HVAC&R systems. Applying the most effective treatment to these units will limit or prevent HVAC&R coil corrosion and its adverse impact, thus saving energy and money and making our environment more sustainable to live in.

THE BIG CHILL

This year, one of the most anticipated sessions will look at the issues faced by the small to medium contractors. It will discuss the concerns of the contractors at the coal/coldface, flammable refrigerant training, licensing, refrigerant reclaim, and training via both TAFE and industry suppliers.

Australia’s must-attend refrigeration industry event is on this month in Melbourne – AIRAH’s Refrigeration 2020 Conference. AIRAH’s annual Refrigeration conference has (ahem) snowballed over recent years, each proving bigger and better than the last. In 2019, a record crowd of 170 attendees turned up in Melbourne to discuss all things frigorific. That included both broad topics and granular details related to the refrigeration industry, feature sessions reviewing the latest developments in legislation and technology, as well as many case studies. The 2020 conference, to be held at the Bayview Eden Melbourne from March 23–24, will cover the same broad range of topics, with some special highlights.

INTERNATIONAL INSIGHT Headlining the event are two experts from OS. Thomas Lund from Danfoss Industrial Refrigeration in Denmark will present on energy efficiency of industrial-size refrigeration systems.

“But using a natural refrigerant does NOT guarantee the highest energy efficiency and lowest indirect emissions of greenhouse gases. Design and control of the system can have a much larger effect on energy efficiency than the refrigerant itself.”

There will be OEMs, industry associations like the Australian Refrigeration Council and Refrigerant Reclaim Australia, wholesalers, and large end-users in the room. This will give them a chance to hear more from the “core” of our industry. Other panel sessions will look at how the global warming crisis could bring the refrigeration and HVAC industries together; applications for heat pumps in refrigeration; and key issues facing end-users.

On top of the keynotes, more than 30 expert speakers will present on everything from flammable refrigerant systems to addressing the skills gap.

A LITTLE BIRTHDAY BASH

ISSUES FROM THE FIELD

Refrigeration 2020 is also the first big event in AIRAH’s centenary celebrations. It’s especially apt because AIRAH was founded as the Victorian Institute of Refrigeration.

The panel sessions are always popular with the audience because of the opportunities they offer for healthy debate and questions from the floor.

Expect a bit of looking back, as well as a whole lot of looking forward. ■

REFRIGERATION 2020 AT A GLANCE

He will present the results of performance tests on different systems, including both natural and synthetic refrigerants. Lund will compare the power consumption results across configurations, sizes and geographical locations and discuss the implications of the different design rules.

Date: March 23–24

Bruce Nelson, M.AIRAH, from Colmac Coil Manufacturing in the US will also look at energy efficiency, focusing on natural refrigerants.

Single day tickets: $395 (AIRAH member) $525 (non-member)

“Without a doubt, using natural refrigerants in our equipment will produce the lowest possible direct emissions of greenhouse gases,” says Nelson.

BEST-PAID TRADE Our industry often bemoans the difficulty of attracting talent, but perhaps we aren’t making enough of one of its biggest drawcards: the money. Willow Aliento looks at whether fridgies really are the best-paid trades in Australia. 20

Cover Feature There might be some high-profile celebrity chippies about, but when it comes to steady wages and ongoing work prospects, according to SEEK’s 2019 salary data, air conditioning and refrigeration technicians are top of the ladder for trade salaries.

More than half of those in the AIRAH survey rate their pay as “good or excellent”. A whopping 85 per cent said they were “fairly satisfied” or “very satisfied” with their pay and benefits, and most expect their wages will either stay the same or even increase in the near future.

In 2019, the average salary for fridgies was $83,278 and salary growth, compared to previous years, a healthy 7.7 per cent. Electricians came in a close second with $82,782.

COMFORT CONDITIONS

While many young people considering their future employment are being urged to go to university and get a degree, there are many reasons here to make an HAVC&R sector career a first choice, including diversity of opportunities for learning and experience and the improved pay prospects.

The vast majority – 89 per cent – are also in permanent part-time or full-time employment, another contrast to the broader labour market trend of increasing casualisation and “gig economy” employment models.

From the outset, the pay proposition is pretty compelling. According to Fair Work Australia, a first-year apprentice can expect to earn at least $500 a week, and pay goes up every year through the apprenticeship. And many employers provide a phone and sometimes even a work vehicle.

It seems that the nature of the work, pay rates, conditions and other factors also make the trade one with a high degree of steadiness in terms of retaining staff.

A university student by contrast is entitled to a maximum of $462.50 per fortnight in Austudy – plus they build up a major HECS debt for the cost of each unit of study. There’s no car. No phone.

AIRAH’s own 2019 salary survey found just over 50 per cent of respondents have a gross annual base salary of $100,000 or more, and over 10 per cent earn $150,000 or more.

Around 70 per cent of those included in AIRAH’s survey expect to stay with their current employer for the next 12 months, and 42 per cent had been with their current employer more than four years.

Granted, the survey covered the wider industry and included not just technicians but also senior engineers, project managers and people in other parts of the business such as sales and human resources. But even looking just at the respondents who classed themselves as RAC mechanics, the average salary was $85,000 – right in line with the SEEK numbers.

Entering the HVAC&R sector also means you’re entering an industry on a growth trajectory. Industry experts point out that the demand for controlled environments is on the rise, whether that is climate-controlled buildings or specialist plant and equipment such as cold storage, laboratories and greenhouses.

In 2019, the average salary for fridgies was $83,278 and salary growth,

It’s worth remembering too, that our industry is filled with people who started on the tools before moving into roles such as project management and business development.

BUILDING AUTOMATION Solutions for Pressure, Temperature, Air Quality, Flow and Thermal Energy Monitoring

Good technicians are essential to keep it all working now, and into the future. HVAC&R is also not “set and forget” equipment. It demands good maintenance and ongoing attention. When plant and equipment doesn’t work properly, the risks include environmental impacts and higher energy costs, equipment failure, or even major public health impacts from spoiled food or medical supplies.

By contrast, other parts of the economy are in decline. A report late last year from Invoice2go found that Australian small businesses were feeling the pinch from a downturn in housing construction, invoicing 7.6 per cent less in FY 2019. But HVAC&R businesses bucked the trend, invoicing 3.8 per cent more.

Cover Feature Following a four-year mature‑age apprenticeship, he moved into specialising in commissioning through a role with his current employer. “I looked for something technically challenging,” Hammond says. As well as undertaking jobs in commissioning HVAC&R plant, Hammond also does some fault-finding work. He says he is “pretty happy” with the salary he’s on. It’s a very broad trade, he says, with a range of opportunities for different personalities and interests, from the puzzle-solving of fault-finding to the handson skills of installation and everything in between. Hammond points out that the job gets you out and about, constantly dealing with new places and new people. There are physical challenges – such as getting gas cylinders through tight spaces or across roofs and into plant rooms – and intellectual challenges too.

HVAC&R attracts some apprentices because of the mix of skills required.

“The work varies a lot,” Hammond says. “One day you might be up in a roof space, the next day you might be in front of the computer.”

MANY TRADES IN ONE In comparison to some trades, HVAC&R is also a “specialist trade”. How the technology works and how to keep it working takes a body of knowledge and experience only those associated with the trade typically possess.

Technology does make the trade more exciting, and it also gives you

There are many aspects that make it appealing to those who enjoy a challenge and are keen on continually learning. Variety is the name of the game.

more marketable skills Standards relevant to HVAC&R are also constantly evolving, so it’s important to stay up to date.

Senior hands in the business describe it as a problemsolving role that involves multiple sets of knowledge including plumbing, mechanical, electrical and IT.

Part of what employers are buying is this growing body of knowledge and expertise.

It’s also a role that involves the personal touch. Dealing with people including asset owners, asset managers, facility managers and others is a fundamental part of the job.

Technicians are also increasingly being regarded as a reliable authority by asset managers and facilities managers in areas including compliance, asset management, and environmental management and energy management.

“It suits a certain kind of person,” says Bryon Price, F.AIRAH, Strategic Development Director at A.G. Coombs Group.

“It is an evolving role,” says Price.

All of these factors make it relatively well paid compared to some trades jobs. There is also a supply‑and‑demand factor at play – the constantly growing demand and current shortage of workers gives qualified fridgies a real advantage when it comes to having the pay conversation.

A COOL FUTURE

It also means employers are keen to offer good money to attract and retain talent. The requirement for being a licensed specialist also means the playing field is restricted to those who hold the relevant qualifications and certifications.

As part of the wider asset management domain, the profession has in many ways transitioned from being task-focused and reactive to being predictive and proactive. It is much more analytical, and fridgies are spending more time diving into the sea of asset information and digital data than they are driving around in a ute from one job to another.

In addition to trade certification, a qualified HVAC&R mechanic might also hold a plumbing licence, licences for handling refrigerants as controlled substances, natural gas and electrical licences.

David Hammond, Stud.AIRAH, Commissioning Technician with Centigrade Commissioning in Western Australia came into the trade after trying his hand at civil construction, IT, carpentry and a stint as a law student.

On top of that, there may be project or site-specific credentials including OHS and site inductions, a confined space ticket, a working at heights ticket and others.

There had been some pressure on him to look at university studies as a first choice after finishing Year 12. But he believes it is false to assume that’s the best path for everyone.

And fridgies can look forward to continuing opportunities to learn and specialise through continued professional development. This includes training in digital technologies and the growing number of data-driven platforms and packages around mechanical systems and plant performance, advanced building management, data analytics, and smart systems including the Internet of Things. Australian

It was a mate who had become a refrigeration mechanic who inspired him to take the opportunity of an apprenticeship. He did his own research, he says, and found there were a lot of interesting aspects to the work and the plant and technology involved.

HVAC&R Nation

www.airah.org.au/nation

Once he started down the path of his apprenticeship, he never looked back.

March 2020

The industry is changing rapidly, including a growing emphasis on energy efficiency and a wide range of new technologies. Communications, particularly digital-based, are also changing the trade, Hammond says. “Technology does make the trade more exciting, and it also gives you more marketable skills.”

A VERY GOOD LIVING Gary Ward, M.AIRAH, Senior Contracts Manager for Ellis Air Conditioning, says the Seek salary estimates reflect what he sees in the industry. The right candidates are able to make a “very good living” in the HVAC&R trade. “We have recently found that we are being approached by previously qualified tradespeople who want to do a dual trade,” he says. They are attracted by the wide variety of work HVAC&R technicians are doing, and the salaries they earn. Ward found during his own apprenticeship that specialisation into either air conditioning or refrigeration as a primary discipline reflected the employer you worked for. He says that although both disciplines finish their trade studies with the same qualifications, and both are related to the refrigeration process, he regards them as two different disciplines within the HVAC&R field. “I personally look back and I am glad that I went the air conditioning side of the trade because of the opportunities that the wide range of AC work offers,” Ward says. At the same time, he recognises many attractive aspects to the work in both air conditioning and refrigeration. Ward mentions the people you meet, the systems both large and small you get to work on. There’s also the importance of the work in the broader context of keeping critical facilities such as hospitals, data centres and pharmaceutical manufacturers cool, as well as ensuring workplaces around the country are comfortable. “Combine all this with the legislation around indoor air quality, essential services, building automation, energy consumption and NABERS ratings, and you have a very interesting work career indeed,” he says.

Cover Feature Getting a foot in the door with an apprenticeship is just the start. A qualified tradie in the sector can go on to specialise in diverse areas including installation, commissioning, service and repair, building automation, and fire and smoke control systems testing. And according to Ward, getting that foot in the door is not hard. The biggest problem is actually one faced by employers, who find so many school leavers are more focused on getting an apprenticeship in plumbing or electrical than HVAC&R. Many only contemplate the sector when they find the other trade studies intakes are full. Of course, it’s valuable for a school leaver or career‑changer to look at the sector first. Ward’s best advice: complete an apprenticeship with a highly respected company. Broader trends within construction and asset maintenance assure the sector of a bright and evolving future. “We have seen a massive shift in focus to both workplace safety and measured energy consumption and the way in which buildings and the sub‑components are designed, selected, implemented, strategically operated via the building control systems and ultimately maintained,” Ward says. This is resulting in a highly trained and experienced workforce who have the ability to think laterally and provide a high-end outcome. And a workforce that is reaping the benefit of their career choice financially. ■

Licensing update

NEW RULES FOR QUEENSLAND FRIDGIES A new mechanical services licensing framework has begun in Queensland. The QBCC explains what it means for you. A new licensing framework has been introduced in Queensland. Workers now require a Queensland Building and Construction Commission (QBCC) licence for mechanical services work. According to the QBCC, “improperly installed and maintained heating and cooling systems can lead to dangerous bacteria growing and spreading through systems in facilities such as aged care, hospitals and shopping centres, among others. For this reason, licensing for mechanical services trades has been changed to reflect the important and specialised skill involved in this work.”

Existing Refrigeration and Air Conditioning and Mechanical Services (Limited Design) and Refrigeration and Air Conditioning and Mechanical Services (Unlimited Design) contractors may also be eligible for a free Mechanical Services – Plumbing licence provided: • The application is made by June 30, 2020 • The applicant has the required technical qualifications • The applicant can show they have performed mechanical services plumbing work (or employed workers to carry out this work) for a minimum period of six months prior to January 1, 2020.

GENERAL INFORMATION All existing licensees in the above classes have been emailed and/or sent a letter detailing the transitional arrangements relevant to them. Regular email updates will be provided to these licensees to ensure the timeframes for applications are understood. The QBCC is working collaboratively with industry stakeholders to ensure mechanical

An online licence application form is available via the myQBCC portal – my.qbcc.qld.gov.au/s/login/ – making the application process convenient and efficient. ■

From July 1, 2020, contractors working in the industry must be licensed to carry out mechanical services work. Other workers, including employees, will not need to be licensed until January 1, 2022 if their employer holds the appropriate contractor licence.

Licensees who are members of industry bodies are encouraged to seek assistance from those organisations to understand the new licensing framework.

New entrants and apprentices completing after January 1, 2020, require a relevant licence to undertake mechanical services work. New entrants include interstate or overseas workers new to the Queensland building industry.

Mechanical services stakeholder meetings are being held regularly to communicate and engage with industry. Further stakeholder meetings will be held throughout the year to gain further feedback and industry insights.

The new licensing framework is being implemented in stages. Plumbers, refrigeration and air conditioning technicians, and those who work in the medical gas industry, will require a licence to perform mechanical services work, or contract for mechanical services work, regardless of the value.

services contractors and workers are prepared for the introduction of the licensing framework, and understand what it means for them.

The QBCC has created a “Mechanical Services Plumbing Licence Experience Requirements” factsheet, available on the QBCC website, which outlines clear examples of acceptable experience. Visit qbcc.build/mechservices to learn more.

STAGED IMPLEMENTATION

All new entrants (including those who complete their apprenticeship from 1 Jan 2020) will need the relevant licence before they can carry out mechanical services work.

EXISTING LICENSEE

All existing licensees with a Refrigeration and Air-Conditioning Licence will be automatically transitioned to the new licence.

COMPANY & NOMINEE SUPERVISOR

All Companies and Nominee Supervisors must be licenced.

SITE SUPERVISOR

All site supervisors (employed by QBCC contractor with mechanical service licence) must be licensed.

EMPLOYEE

All employees (of QBCC contractor with mechanical services licence) must be licensed.

Students performing work as part of an apprenticeship/traineeship will not require a licence.

Visit the mechanical services web pages at qbcc.build/mechservices to access detailed information for each mechanical services stream, including timelines for licencing, reference guides and fact sheets, transitional arrangements and information on how to apply for recognition of prior learning for mechanical services technical qualifications.

5 NEW OWNER FOR ACD TRADE

7 CLASS DISMISSED

with their TAFE/RTO fees and textbooks, and $1,000 to help newcomers build their all‑important trade toolbox.

Global refrigeration wholesaler Beijer Ref AB has signed an agreement to acquire all shares in the Australian HVAC company ACD Trade.

Trades College Australia in Punchbowl, Sydney, has lost its RTO status for issues related to the delivery of recognition of prior learning (RPL) for refrigeration and air conditioning (RAC) courses.

“Following feedback from apprentices, plumbing teachers and employers, we’ve determined that the greatest financial hardships are associated with tuition and tools,” says Rheem CEO Chris Taylor. “The grant provides recipients with the opportunity to commit to further study, such as continuing the optional fourth year where apprentices can earn their tradesman license and dream of one day operating their own business.”

ACD Trade is a leading HVAC distribution company in Australia with around 60 employees and a distribution network of nine branches. Annual sales amount to approximately Au$80 million. Beijer Ref acquires ACD Holding Company Pty Ltd. from Cliplight US Holdings, Inc. The Group is already present in Australia through Beijer Ref Australia and Kirby HVAC&R – formerly Heatcraft, which Beijer Ref acquired in 2018. The acquisition of ACD Trade further strengthens the group’s presence in the Asia Pacific region and especially in Australia. Total sales in APAC are estimated to top Au$460 million after the acquisition, corresponding to 20 per cent of Beijer Ref´s total sales. “Australia is an important market for us, and it is pleasing that we found an opportunity to grow further,” says Beijer Ref CEO Per Bertland. “ACD Trade is a well-managed and fast-growing company that will add value to our group in the form of an expanded customer base and a broader product range within HVAC.” ■

6 ACTROL BRANCH IN BALLARAT HVAC and refrigerant technicians in Ballarat and surrounds in regional Victoria will be pleased to learn that a new Actrol and relocated Metalflex branch has just opened in Delacombe. “The dual-branded site provides the best-quality products and service for all refrigeration and air conditioning installers,” says Actrol. “The branch prides itself on a well-stocked product range and an expert technical team to support customers.” The branch, located at 24 Wiltshire Lane, is open six days a week. “Visit to explore the broad range of products and learn how the team can support your upcoming projects,” says Actrol. Go to actrol.com.au or metalflex.com.au ■

The Australian Refrigeration Council (ARC) worked with the Australian Skills Quality Authority (ASQA), the training industry regulator, on the case. ASQA took action against Trades College Australia and, after numerous appeals, has cancelled the RTO.

Applications close at 5pm on March 30. Successful recipients will be announced on May 8.

“A significant element of ASQA’s review revolved around the use of recognition of prior learning,” says ARC CEO Glenn Evans, Affil.AIRAH.

Go to www.rheem.com.au/apprentice ■

“RPL needs to be conducted with the same rigour as any other form of assessment, including a comprehensive quality process that covers the content (skills and knowledge) of the qualification being assessed.”

9 CHOICE EFFORT!

For a qualification that usually takes several years to complete, such as a Certificate III in refrigeration and air conditioning, the documentary evidence for an adequately assessed RPL qualification could be hundreds of pages. This must be detailed and mapped across each unit of competency. “With the help of industry, the ARC and the ASQA, sub-standard RAC training courses have been all but eliminated,” says Evans. If you believe an RTO is offering refrigeration and air conditioning qualifications inappropriately, you can report the issue via email: enquire@arctick.org ■

8 KNOW A GOOD PLUMBER? Rheem Australia has announced the launch of its Apprentice Plumber Grants for 2020. Australian apprentice plumbers and gas fitters, both current and those who are this year starting their TAFE/RTO course, can apply for a share of the $30,000 in grants available from the scheme. Ten successful candidates will receive a $3,000 grant to support the progression of their study and help kickstart their career: $2,000 to assist

Capping off its 20th anniversary last year, Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) was recognised as the Best Brand of Air Conditioners by leading consumer advocacy group Choice. The award is based on test reviews of over 140 split system air conditioners and the results of the annual reliability and satisfaction survey completed by more than 7,500 Choice members. According to Choice, the Best Brand recommendation is earned by companies with a clear lead over their competitors during the test period. Factors include performance over the past 12 months, customer satisfaction and reliability information submitted by Choice members on their experience with the brand. This is then combined with the bi-annual review of split systems conducted independently by Choice. “Receiving this honour for the second year in a row highlights the quality product we are bringing to the Australian market,” said MHIAA managing director Yuji Ito. “We believe in keeping consumers at the forefront of our heating and cooling solutions and going above their expectations to help them find the perfect AC solution for their needs.” Go to mhiaa.com.au ■

GET A PIZZA THE ACTION The outdoor oven you’ve always wanted is more convenient than ever. A hand-built outdoor pizza oven is on the wish list for many of us. But let’s be honest: they are a lot harder to build than those YouTube videos suggest. A new portable gas-fired option could be the just the answer for the time-poor or DIY skills-challenged artisanal pizza lover. “Ooni Koda’s award-winning, portable design is crafted for ultimate speed, convenience and ease of use,” the company says.

Featuring instant gas ignition, the mini oven is ready to cook in 15 minutes, reaching temperatures up to 500°C. In addition to cooking Neapolitan-style pizza, with a twist of a dial the Ooni Koda can handle fish, vegetables and steaks. “Ooni Koda fires out jaw-dropping pizzas in 60 seconds flat,” the firm says. “No mess, no assembly, no fuss. Cooking outdoors with gas has never been so simple or so beautiful.” Very little assembly is required.

foldable legs, insert the stone baking board, and connect to a gas tank.” Online reviews suggest that if you’ve been entertaining thoughts of acquiring an outdoor pizza oven, the Ooni Koda is a good place to start. “Cooking with a pizza oven is a highly enjoyable experience, and the Koda makes it easier than ever,” one reviewer declared. “What you might sacrifice in wood-smoked flavour and danger, you win back in convenience.” But how much dough will you need? RRP is $480 from various Australian outlets. ■
