Editorial
BATTLE OF THE GASES In case you haven’t noticed, the refrigerants market is going through a critical transition period right now. The HFC phase-down has meant that some gases will disappear, and others will take their place. Obviously, it’s a huge commercial opportunity for companies that can fill the gap. But what gases will replace HFCs? That is the big question, and there are two strong and opposing voices offering an answer. On one side we have producers of new “fourthgeneration” synthetic gases called HFOs. These gases are similar to HFCs but break down much faster in the atmosphere and have a much lower global warming potential (GWP). Some can work in pure form as a replacement. In other cases, blends of HFCs and HFOs are being used as drop-in solutions. Either way, they can help us meet the phase-down targets by reducing the overall GWP of the refrigerants we use.
On the other side we have providers of solutions that use natural refrigerants such as ammonia, CO2 and hydrocarbons. This camp suggests that HFOs have new environmental impacts that are yet to be fully investigated. Some have gone so far as to say that the new gases are nothing but a marketing ploy – HFCs with a new name. Could the answer simply be a combination of HFOs and natural refrigerants? Most probably. But make no mistake, there are some big investments riding on which solution comes out on top. So when you read an article criticising one approach or another, it’s a good idea to check the source and look for any commercial links.
Of course, there are actors who remain neutral, and AIRAH as a not-for-profit representative of the HVAC&R industry is one of them. Given the state of play, we wanted to bring you a story on HFOs that was not biased by commercial interests. Regular writer Sean McGowan has done a great job of presenting the information from both sides. You can read his feature on page 10. There are still a lot of unknowns as we try to find the best path towards a more eco-friendly future, but sorting out the information from the vested interests is a good start. @AIRAHnews

Frigel solution adds up
07
Panasonic has unveiled AC Smart Cloud, a cloud-based system that allows remote monitoring and control of air conditioning systems in multiple locations.
Process cooling expert Frigel has announced a new line of Microgel machine-side chiller/temperature control units (TCUs) with digital controls that capture energy consumption data. The company claims that the units’ ability to display and record this information marks an industry first. “At Frigel, we’re continuously advancing our technologies to help plastics processors effectively compete,” says Frigel North American marketing manager Al Fosco. “That includes giving them the ability to capture and leverage more processingcooling data to drive key business decisions. Now for the first time, plastics processors can capture and record energy consumption data for extended periods, which is critical given that energy use for cooling is considerable. That data, in turn, fuels opportunities to lower operational costs and increase product profitability.”
Cloud power
The solution is targeted to organisations such as universities, which have a number of buildings across a campus, as well as aged-care facilities, hospitality, retail and government. It is fully scalable so it can be adapted to the needs of a business – from a franchise to a large facilities company. 06
In addition to energy consumption, the Microgel digital controls give users the ability to review temperatures, pressures and flow rates. Operating data is stored in a historical log and is accessible via a touchscreen. This can help inform decisions on operating settings, to make the moulding process more efficient.
A Cloud Adaptor, which is connected to the Panasonic heating and cooling installations at each premises, feeds real-time data and information via a central cloud portal directly to the user. This includes temperatures, running time, error logs and alert notifications, energy efficiency and performance statistics, and alarms. The system does not require specialised software – users can log in using a standard web browser. Panasonic’s product marketing manager for air conditioning Jack Tey says: “The new system allows accurate and instant monitoring and control, so companies can compare performance across locations and develop best practice in building energy management.” 07

Global Update
TUVALU
SOUTH KOREA
ISLAND ON THE RISE
GOLD BUT NOT GREEN
MAHALO AIRCON
Research has shown that the tiny Pacific nation of Tuvalu – long seen as a prime candidate to disappear as climate change forces up sea levels – is actually growing in size.
Organisers of the recent Winter Games in South Korea set a goal of becoming the first zero-emissions event in Olympics history. But the refrigerants used in the Pyeongchang ice arenas were some of the most potent climate-warming HFCs on the market.
Spare a thought for students in Hawaii, where classroom temperatures often soar past 30°C. Now the Hawaii State Department of Education has intervened, putting together a US$100 million fund to solve the problem. To date it has cooled down more than 1,200 classrooms, with more to come.
A University of Auckland study examined changes in the geography of Tuvalu’s nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery. It found that Tuvalu’s total land area increased by 2.9 per cent, even though sea levels in the country rose at twice the global average. Factors such as wave patterns and sediment dumped by storms offset the erosion caused by rising water levels. The Auckland team says climate change remains one of the major threats to low-lying island nations. But it argues the study should prompt a rethink on how such countries respond to the problem. n
HONG KONG
All the ice skating and hockey venues – including four constructed since 2011, when South Korea was named host – used refrigerant R404A, which has a global warming potential of 3,922. The decision may have been based on familiarity, or choosing the equipment that was most readily available before the start of the games. In the US and Canada, 20 NHL arenas use HFCs or HCFCs, compared to 11 using natural refrigerants such as ammonia. The newest NHL arenas – in Las Vegas, Detroit and Edmonton – all have ammonia-based ice plants. n
JORDAN
USA
The Department partnered with Tesla to pair Powerwalls (battery units) with photovoltaic cells. As a bonus, it also gives students the chance to learn about renewable energy and energy storage. Hawaii has some of the highest electricity rates in the US, and 93.7 per cent of its energy comes from non-renewable resources such as petroleum and coal, so it is now investing heavily in solar energy. The state also has several initiatives to combine renewable energy production with energy storage. n
SWITZERLAND

DESERT TEST
BANKING ON NUKES
A study by Hong Kong Baptist University scholars has revealed that skin squames – cells that peel off from the skin surface – can produce bad smells in air cooling units.
The Al Salam military supermarket in Amman, Jordan, has become the testbed for the Middle East’s first trial of a transcritical CO2 refrigeration system.
Skin squames consist of keratins, structural proteins that can be broken down by bacteria that colonise air conditioning units. This in turn produces ammonium, which can produce a urine-like smell.
The project seeks to prove the feasibility of non-HFC-based technology in hot climates. It will monitor efficiency results, looking at CO2 as an alternative to R22, which is still often used in retail installations in many developing countries. The work in Jordan is part of three ongoing demonstration projects in Chile, Jordan and India to showcase the possibilities of HFC-alternative technologies.
Switzerland generates up to 40 per cent of its electricity through nuclear power. According to the World Nuclear Industry Status Report 2017, it also operates the oldest plants in the world, with an average age of 42 years.
Other than keratins, skin squames contain other microbial nutrients that can also be degraded by bacteria into different kinds of volatile short-chain fatty acids often linked to the smell of body odours. Researchers reported that the best way to control these smells is to install an appropriate filter. Skin squames are generally larger than 10 micrometres, so a filter that can effectively capture particles of this size should help improve the odour problem. n

The system at the 2,000m² Al Salam supermarket is a CO2 transcritical booster system with parallel compression. It is able to maintain chilled food at set-point temperatures with an evaporation temperature of -2°C, while the frozen foodstuff is cooled by evaporating CO2 at -25°C. n
Now, the SolarSuperState Association – a Swiss non-profit non-governmental organisation – has highlighted the potential damage that could be caused throughout Europe if one or more of the plants failed. It is calling on the European Union to demand a guarantee from Switzerland of at least €500 billion to be deposited against negative interest rates at the European Central Bank in the event of a plant failure. The Association points to the increased risks of extreme weather events and terrorist acts affecting the plants. Switzerland is phasing out nuclear power, as confirmed in a 2017 referendum. n

BALANCING ACT HFO BLENDS
To assist the HVAC&R industry transition away from HFCs, HFO-HFC blends have been developed as an interim measure. The blends include R513A (marketed under several brand names). R513A is a blend of HFC-134a and HFO-1234yf and has been developed to replace HFC-134a in some systems. It has a GWP of 573, which is less than half that of R134a. Other HFO blends include R448A (replacing R404A and R22), R449A and R452A (both replacing R404A and R507). John Morgan is technical manager for refrigerant and gas at Heatcraft. He says HFO blends are a transitional refrigerant required to keep the marketplace supported during the HFC phase-down. “Not all refrigerants being introduced to the market today are pure HFOs,” he says. “The equipment currently in service and being sold today needs to be supported through the phasedown activity. So HFO blends play an important part in the step-change in order to maintain the non-flammable classification and compliance requirements.”
With the HF C phase-dow n now unde a new type r way, of alternativ e refrigerants emerged. Se called HFOs an McGowa have n explores th these next-g e issues asso eneration ga ciated with ses, and loo ks at the role as the indus they could p try moves in to a critical tr lay ansition peri od. On January 1 this year, a historic event took place in Australia’s HVAC&R sector: the government began to phase down the quantity of hydrofluorocarbon (HFC) bulk gas that can be imported into the country. The phase-down was enacted under the internationally ratified Kigali Amendment on HFCs (an extension of the Montreal Protocol on gases that deplete the ozone layer), and will see a gradual reduction in import quotas over the next 18 years. By 2036, Australia has committed to reducing HFCs by 85 per cent. As a consequence, the HVAC&R industry will need to transition to other low or zero global warming potential (GWP) refrigerants. These include natural refrigerants such as ammonia (R717), carbon dioxide (R744), and hydrocarbons (R290 propane, R1270 propylene and R600a isobutane) – all of which are finding a niche in certain markets, including supermarket refrigeration. Another alternative that has entered the market are hydrofluoroolefins or HFOs.
THE SCIENCE OF HFOs Commonly referred to as fourth-generation refrigerants, HFOs feature a similar chemical structure to HFCs. What sets HFOs apart is that most have a chemical double-bond between atoms (HFCs only have single bonds), which allows them to break down very quickly in the atmosphere. This results in very low GWP. For example, the atmospheric lifetime of HFO-1234yf is estimated to be about 11 days compared to HFC-134a (R134a), which has an atmospheric lifetime of 14 years. Additionally, HFOs have zero ozone-depleting potential (ODP) because they contain no bromine or chlorine atoms, and are destroyed in the lower atmosphere. In their pure form, however, HFOs are generally classified as flammable, and are therefore not a suitable drop-in replacement for HVAC&R systems operating on HFCs.
10 | HVAC&R Nation | www.airah.org.au/nation | April 2018
R448A is a blend of the HFCs R32 (26%), R125 (26%) and R134a (21%), with HFO components R1234yf (20%) and 1234ze(E) (7%).

HFO SIGHTINGS – THE STORY SO FAR
The idea that HFOs are simply HFCs rebranded oversimplifies the issue
HFCs REBRANDED?
Daikin recently launched a new range of chillers that use the HFO R-1234ze (E).
Despite the obvious low-GWP advantages that HFOs offer, environmental groups like Greenpeace have already been active in opposing their uptake as newgeneration refrigerants.
“Some are flammable and some are not. HFOs are a form of HFC that have been developed to break down rapidly after they are emitted and to have a low impact on the climate system.”
Prepared by Risk and Policy Analysts, the report notes that the consensus among academics is that

TFA is produced when some HFOs break down in the atmosphere. Similarly, some – but not all – of the more traditional HFCs also produce TFA when they break down.

A study on the environmental and health effects of HFO refrigerants was prepared for the Norwegian Environment Agency in December 2017. The study found that a number of knowledge gaps exist about the environmental impact of trifluoroacetic acid or TFA – an atmospheric by-product of HFOs.
The Montreal Protocol’s Scientific Assessment Panel reported on breakdown products in its 2014 Quadrennial Assessment Report. It summarised its review of TFA as follows:

Concerns have been raised by environmental groups, academics and some members of the HVAC&R industry as to the toxicity of pure HFOs – particularly after they break down in the environment.
2023
As with most new products on the market, HFOs also have their detractors.
A: Yes. R1234ze is available now. Customers should check their local branch for more information.
“TFA will have a negligible effect on the environment,” but points to a number of knowledge gaps that need to be filled to support that conclusion. These include studies on the cycle of TFA in the atmosphere and hydrosphere, the amount of TFA used globally, and other potential sources of TFA in the environment.

“All HFCs have individual characteristics – some have high global warming potential, some are low,” the spokesperson says.
A: HFO blends are presently more expensive in comparison to HFCs. But as volume usage of HFO blends increase, the costs are expected to decline and will reach a price parity with HFCs. This will be the point where the largest switch away from HFCs to HFOs will be seen.
A: The large commercial sector tends to embrace the technology first, due to the level of investment and installation lifecycle expectation by the specifiers/end users.
2020
However, a spokesperson for the Department of the Environment and Energy says the idea that HFOs are simply HFCs rebranded oversimplifies the issue.
Their use in HVAC in particular may initially be limited but will increase as equipment is geared towards the newer refrigerants.
Q: W hat about the pricing of the HFO blends compared to the HFCs that they are replacing?
Q: A re there any particular areas of the industry or applications where they are being used?

“We should not use the brand name introduced by the manufacturers,” Hafner adds. “Unsaturated hydrofluorocarbons is the correct description of these HFCs, or short-life HFCs.”
A: HFO blends have been available for the past one to two years. As the product gains acceptance through trials, the demand is growing.

“Unsaturated hydrofluorocarbons represent another kind of HFCs, which are potential replacements for HCFCs and saturated HFCs, especially in air conditioning units,” he says.
use in their existing and new generation equipment. For example, Heatcraft is currently in the process of releasing new literature incorporating the use of R448A across its Kirby condensing unit and refrigeration equipment range.
Q: H ow long have the HFO blends been in Australia, and how is this market developing?
2017
Dr Armin Hafner from the Norwegian University of Science and Technology also prefers to call HFOs by another name.
John Morgan, Heatcraft Australia technical manager, refrigerant & gas, filled us in on how much HFOs and their blends have penetrated our market so far.

In a position paper released in July 2016, Greenpeace said that HFOs are a form of HFC being marketed under a different name “due to the negative connotations that HFCs have acquired”.

Cover Feature (HFO-1234yf) yields the persistent degradation product trifluoroacetic (TFA) upon atmospheric oxidation. While the environmental effects of TFA are considered to be negligible over the next few decades, potential longer-term impacts could require future evaluations due to the environmental persistence of TFA and uncertainty in future uses of HFOs.”
TWO MINUTES WITH
DR ARMIN HAFNER
Briefing notes from a UN Environment Program meeting state that current and future use of HFCs and HFOs are estimated to add less than 0.1 per cent TFA input to oceans and salt lakes to amounts already present from natural sources. “More than 95 per cent of the salts of TFA found in the oceans are naturally produced,” says the briefing note. “These salts are inert and not of toxicological or environmental concerns in small concentrations that are present in the oceans, playas, and lakes.” Tayler Stevenson, Affil.AIRAH, product manager of factored gases at BOC, says further research has drawn similar conclusions. “A study in the Journal of Geophysical Research found that even if every vehicle in the USA had R1234yf, concentrations of TFA in rainwater will remain well below safety limits,” says Stevenson.

A: If we do good engineering and apply current safety standards, 99 per cent of all HVAC&R units can be made applying natural working fluids (refrigerants). These systems with natural working fluids will also be more energy efficient than those applying available HFCs.
Flammability can be handled, and there are no decomposition products in case of an event with hydrocarbons. In the case of small leaks from HFC (high-GWP and short-life) indoor units, there is a large risk that the fluid is decomposing inside the house if there are hot surfaces (oven, etc.)
Q: Why has the HVAC&R industry (at least in Australia) been slow to move to natural refrigerants? A: Business as usual is low risk. However, if the market is changing and the end users are informed, it is a good opportunity for first movers to gain market share. Training is key, too. Q: You have just been in Sydney to attend the Refrigeration 2018 conference. What was the focus of your visit? A: The focus was on natural working fluids. These fluids do have favourable thermodynamic and fluid properties enabling energy-efficient refrigeration system configurations. In addition, their environmental impact is well known and safety standards are established.
Nevertheless, Hafner says the acidity of TFA is approximately 34,000 times stronger than that of acetic acid, and can be harmful when inhaled, causes severe skin burns and is toxic for water organisms even at low concentrations. Another atmospheric product of some HFOs is hydrogen fluoride (HF), which upon contact with moisture immediately converts to hydrofluoric acid and is both highly corrosive and toxic. “As long as the fluids stay inside the systems, everything is okay,” says Hafner. “However, in reality these units do have leaks and decomposition will take place, even without a fire or an accidental event.”
RISK-FREE REFRIGERANT? NO SUCH THING What is clear is that each refrigerant offers distinctive characteristics, and each carries its own set of risks – be it flammability, toxicity, overall emissions, performance or cost. “It is about choosing a refrigerant best suited to the application,” says Stevenson. “Refrigerants have always offered a choice of characteristics, however, due to the laws of physics and chemistry there are trade-offs, which is why so many options are available.” And according to Morgan, there will be no risk-free refrigerants in the future. “As with natural refrigerants, it often comes down to the application, and the effects that methods to manage the risks have,” he says. “That is why occupancy and location factors are now so important in informing the selection of fluids.”

He says that HFO blends being offered to the market, such as R448A, still offer the best solution for the immediate future in support of a development equipment market. “The move to further develop equipment for low-GWP refrigerants will continue with all OEMs (original equipment manufacturers), as is the intent of the Montreal Protocol.”
WILL HFOs END UP THE WAY OF CFCs, HCFCs AND HFCs? “A friend of mine brought it to the point,” says Hafner. “It took 60 years (1930 to 1990) to acknowledge that CFCs damage the ozone layer. It took 30 years (1990 to 2020) to acknowledge that HFCs contribute to global warming. It will take maybe less than 15 years to acknowledge that HFOs are harmful to the local environment.” While it’s entirely possible that HFOs will be phased down or out in the future, for now the industry’s major manufacturers and distributors see HFOs as the next evolution in refrigerants. “Currently, HFOs offer the best balance of benefits, including low emissions, with no foreseeable end,” says Stevenson. “HFOs are endorsed or approved by peak organisations such as the EU, EPA (USA) and the National Industrial Chemical Notification and Assessment Scheme (NICNAS) in Australia. Overwhelmingly, it seems that with current technology, the low-GWP benefits of HFOs are one of the best solutions to reduce the overall global warming impact of HVAC&R.” Although the federal Department of the Environment and Energy does not promote or recommend particular solutions, it does recognise HFOs as being one of the answers to the HFC phase-down. “Other refrigerants such as ammonia, carbon dioxide and hydrocarbons will also be part of the solution, as well as non-chemical approaches such as evaporative cooling,” says a Department spokesperson. “And there is also exciting technology emerging such as phasechange materials and magnetic refrigeration.” Ultimately, however, it will be the market that determines the future of HFOs and how they will compete alongside natural refrigerants and new technologies. Only time will tell. n
Want to know more? The Speaker Series at this year’s ARBS conference features a session looking specifically at HFOs. The talk will be given by Honeywell’s Global Business Manager – Refrigeration, Robert Kebby. According to the program, the session will provide the audience with a clear understanding of how HFOs combined with diverse refrigeration architectures are already impacting the industry, through improvements in energy efficiency, refrigerant charge / leak reduction, total cost of ownership and reduced overall environmental impact. The session will examine case studies on end users who are experiencing challenging economic conditions and have chosen to primarily focus on the Total Cost of Ownership (TCO) of refrigeration.

THIRST FOR DISCOVERY The prospect of using MOFs for sustainable water filtration is incredibly exciting from a public good perspective MOFs are sponge-link crystals that have the largest internal surface area of any known substance, and can be used to capture, store and release chemical compounds. Currently, reverse-osmosis membranes are the most common material used in water desalination. They are also employed in the last stage of most water treatment processes. But MOFs could use two to three times less energy.
Australian researchers may have scored a double whammy by developing a system for more efficiently desalinating seawater – and harvesting lithium at the same time.
What does the world need now? Well, plenty of things, but two substances in great demand are drinking water and lithium. According to the World Health Organisation, more than two billion people still do not have access to clean and safe drinking water. Meanwhile, increased use of electronics and batteries is driving demand for lithium skyward. Now, a team at Monash University working with the CSIRO and the University of Texas have made a breakthrough that could provide better supplies of both, using materials called metal organic frameworks (MOFs).
MOFs not only filter out salt ions, they also collect metal ions such as lithium, which is plentiful in seawater. “This has implications for the mining industry that currently uses inefficient chemical treatments to extract lithium from rocks and brines,” says Professor Huanting Wang from the Monash team. “The prospect of using MOFs for sustainable water filtration is incredibly exciting from a ‘public good’ perspective,” says the CSIRO’s Dr Anita Hill. “And delivering a better way of extracting lithium ions to meet global demand could create new industries for Australia.” n

REFRIGERATION SAFETY AND ENVIRONMENTAL REQUIREMENTS STANDARD AS/NZS 5149
PROUDLY SPONSORED BY
AIRAH
Skills summary n What?
A guide to the updated standard AS/NZS 5149, which deals with safety aspects of design, construction, installation and inspection of refrigeration and heat pump systems
n Who?
PULLOUT
HVAC&R apprentices, teachers, lecturers, contractors, facility managers, installers, mechanics/technicians and maintainers.
Standard AS/NZS 5149 specifies requirements for the safety aspects, in terms of the design, construction, installation and inspection of refrigerating appliances, systems and ancillary equipment intended for use or installation in institutional, public assembly, residential, commercial and industrial occupancies. It applies to all stationary or mobile refrigerating systems excluding vehicle air conditioning. It can be applied to new systems, and existing system modifications, relocations and conversions, and also applies in the case of the conversion of a system for use with another refrigerant. It contains nearly one hundred helpful definitions related to system types, system locations, system pressures, system components, piping components, safety devices, working fluids, and refrigerant disposal.
PART 1: DEFINITIONS, CLASSIFICATION AND SELECTION CRITERIA One of the most important functions of this standard is to enable a determination of the maximum safe quantity of refrigerant (charge) that is permitted in a particular system, based on the type and application of the system and the AS/NZS ISO 817 refrigerant classification. The standard also specifies system safety and environmental requirements for different refrigerant classifications based on the occupancy classification, the system classification and the location classification. There are three categories of occupancy: General occupancy – a Supervised occupancy – b Authorised occupancy – c
In 2016, Standards Australia adopted and published the new refrigeration safety and environmental standard AS/NZS 5149 Refrigerating systems and heat pumps – Safety and environmental requirements, replacing AS/NZS 1677.2:1998. The new AS/NZS 5149 standard is published in four parts comprising over 160 pages of technical safety and environmental requirements. This Skills Workshop looks at the content of AS/NZS 5149.1:2016 Part 1 Definitions, classification and selection criteria and AS/NZS 5149.2:2016 Part 2 Design, construction, testing, marking and documentation. It complements Module 102, which can be found in HVAC&R Nation, June 2017.
A list of typical examples is provided for each in Table 1. In Australia and New Zealand, machinery rooms are considered Authorised occupancy – c.

Examples
eneral G occupancy –a
Rooms, parts of buildings, buildings where: • Sleeping facilities are provided • People are restricted in their movement • An uncontrolled number of people are present, or • To which any person has access without being personally acquainted with the necessary safety precautions.
Hospitals, courts or prisons, theatres, supermarkets, schools, lecture halls, public transport termini, hotels, dwellings and restaurants.
Supervised occupancy –b
Rooms, parts of buildings, buildings where only a limited number of people can be assembled, some being necessarily acquainted with the general safety precautions of the establishment.
Offices, laboratories, places for general manufacturing, workplaces.
Authorised occupancy –c
Rooms, parts of buildings, buildings where only authorised persons have access, who are acquainted with general and special safety precautions of the establishment and where manufacturing, processing, or storage of material or products takes place.
Manufacturing facilities, for example, for chemicals, food, beverage, ice and ice-cream. Refineries, cold stores, dairies, abattoirs, and nonpublic areas in supermarkets.
Note: Occupancies can be classified by national requirements
Table 1: Categories of occupancy (from AS/NZS 5149.2:2016)
There are two main types of system classifications: direct and indirect. This is based on the heat transfer method used and the potential for leaks to enter occupied spaces, with several sub-categories within each class. For clarity the standard provides a schematic drawing of each system type. • Direct systems do not use a secondary heat transfer fluid and include direct, open-spray, direct-ducted, and open-vented spray systems. • Indirect systems do use a secondary heat transfer fluid and include indirect closed, indirect vented, indirect vented closed, double-indirect and high-pressure indirect systems.
There are four location classifications for these systems: Class I Refrigerant-containing parts located within an occupied space Class II C ompressors and pressure vessels located in a machinery room or in the open air Class III R efrigerant-containing parts located in machinery room or open air Class IV Refrigerant-containing parts located in a ventilated enclosure.

Table 2: Refrigerant Safety Classifications (from AS/NZS ISO 817:2016)
The maximum charge of refrigerant allowed in any specific application is calculated in accordance with the procedures of Annex A in the standard. This maximum quantity refers to the largest charge of any single refrigerating system within a space; each separate system or independent circuit is considered separately. Maximum refrigerant quantities cannot be calculated for systems and appliances already covered by IEC or ISO product standards that specify refrigerant quantity limits. For example, allowable charge limits for multi-split and VRF air conditioners using A2L refrigerants are defined in AS/NZS 60335.2.40, so Annex A and Clause A.5 are not applicable to those system types. Annex A outlines how to calculate the refrigerant charge limit for toxicity-based limits and flammability-based limits. The allowable charge can exceed this or be restricted below this under certain circumstances. For example, for spaces above 250m2 floor area the charge limit calculations must use 250m2 as the floor area. The charge limits for flammable A2L, A2, and A3 refrigerants are capped to a limit based on the LFL. For A2L refrigerants this cap is increased by a factor of 1.5 in recognition of the lower burning velocity of these refrigerants. A1 and A2 charge limits are calculated based on the classification of occupancy, the system location and the class of the refrigerant. The charge limit is either the toxicity limit, which is based on the RCL, or the flammability limit, which is based on the LFL – whichever is smaller. Tables B1 and B2 provide all the refrigerant data required, including the safety classification, the practical limit, the ATEL/ODL, the LFL as well as environmental data such as the ODP and GWP of the refrigerant. The standard also specifies how the space volume calculations must be carried out, for every space where there are refrigerant-containing parts. It clarifies how multiple inter-connected spaces, ducted multi-enclosure systems, building voids and false ceilings are treated. Volumes used are nett volumes, with appropriate allowances made for stored product, fittings and fixtures. Where charge limits for A1 and A2L refrigerants are exceeded in a space, the system can still comply if special provisions are made to ensure at least an equivalent level of safety. These special provisions are detailed in paragraph A5 where the allowable refrigerant charge can be increased using QLMV
Determine the charge limit based on flammability (from LFL) Lowest charge limit applies
(Quantity Limit with Minimum Ventilation) or QLAV (Quantity Limit with Additional Ventilation). Special provisions can include natural or mechanical ventilation, safety shut-off valving, and safety alarms used in conjunction with refrigerant gas detection. The standard also outlines how heat transfer fluids used in indirect systems must be treated, if they are one of the types listed in Annex B. Annex C is an informative appendix that outlines some of the potential hazards for refrigerating systems that result from extremes of temperature, excessive pressure, refrigerant charge issues, refrigerant leaks and plant operation. The variations made to ISO 5149.1:2014 to make it suitable for use in Australia and New Zealand are listed in Appendix ZZ. Appendix ZA has been added to provide worked examples of determining allowable charge limits for several different refrigerant scenarios. Calculation of allowable charge limits can be complex given the many variables involved, and examples have been provided to assist users of the standard. These include: • A machinery room for refrigerant R290 • A supermarket medium temperature rack system using R134a – public area • A supermarket medium temperature rack system using R134a – plant room • Self-contained refrigerated display cabinet using R290 • Cool room with a remote condensing unit for refrigerant safety Group A1 – no public access • Cool room with a remote condensing unit for refrigerant safety Group A1 – with public access • Cool room with a remote condensing unit for refrigerant safety Group A3 – with public access. Appendix ZB outlines the relationship between the refrigerant safety classification system of AS/NZS 5149, the Australian Dangerous Goods

(ADG) code and GHS classification systems (see below). These systems use different flammability classifications and the Appendix has been provided to clarify any potential confusion and misapplication.
PART 2: DESIGN, CONSTRUCTION, TESTING, MARKING AND DOCUMENTATION This part of 5149 contains all the technical detail in relation to the design and construction of the system including pipes, piping components and fittings, component and system testing, marking and documentation, as well as the requirements for assemblies of components. More stringent requirements apply as the toxicity or flammability classification of the refrigerant increases (see Table 2). Class 2L refrigerants must comply with the same requirements as Class 2 refrigerants unless specifically excluded or varied in the standard. There are several areas in ISO 5149.2 where stringency has been reduced for Class 2L refrigerants and several areas in AS/NZS 5149.2 where these stringency reductions have been amended (removed) for Australian use, for example excluding A2L refrigerants from the concessions of Clause 5.2.3.7 and amending Clause 5.2.7.2 to not allow fusible plugs to be used with A2L refrigerants. The standard covers general requirements for pipes, components and assemblies, and specific requirements for piping joints, isolating valves, and materials that are used in the system. See for example Table 3 on copper pipe supports.

The testing required includes strength-pressure tests to establish fitness for purpose (which includes component testing, strength type testing or fatigue testing), tightness tests (to detect potential leaks) and a functional test of all the electrical safety circuits. The completed installation must also be inspected and safety-verified with the results recorded. A system visual inspection checklist is provided in Annex A. Installation is covered in detail in the standard including location, access, pressure limiting arrangements, protection devices, testing, marking and documentation. As components are assembled into systems the standard covers issues such as plant support, maximum allowable pressures, pipe and fitting assembly, pipe location, support and protection, draining and venting arrangements, shut-off devices, pressure relief and relief pathways. There are a range of options available for pressure relief and a comprehensive four-page decision flow chart guides users through the various safety considerations and decision points for pressure protection.
HVAC&R Skills Workshop CLASSIFICATION CONFUSION Appendix ZB of AS/NZS 5149.1 clarifies that the refrigerant R1234ze is classified as Lower Flammability A2L by ISO 817 but it is classed as non-flammable, non-toxic under the ADG and GHS systems; “Division 2.2” under ADG, and as “Gas Under Pressure H280” under GHS.
PULLOUT
Most other A2, A2L (R32, R1234yf) and A3 (R290, R600a) refrigerants are classed as “Division 2.1 Flammable gases” under ADG, and as “Flammable Gases Category 1 H220” under GHS.
To determine which specific requirements apply, the assemblies must be categorised into one of four risk categories I, II, III, or IV depending on the GHS classification of the refrigerant, the phase of refrigerant in the assembly (gas/liquid), the strength pressure (PS) and the volume of the vessel or diameter of pipe/fitting. The risk category of the “assembly” is determined based on the highest risk category of the components it consists of.

Cool Tech
TOP OF THE CHOPS This month we put aside the electronic gizmos and reach for an old-school classic: Best Made’s American Felling Axe.
But if you think that all sounds a bit poncey for something basically designed to chop stuff up, rest assured that Best Made’s products are created with hard work in mind.
Although the company naturally talks up the quality of its products, some reviewers claim the Best Made axes are not much chop. If you’re looking for a straight working tool, there are better options out there – Fiskars and Husqvarna, for example, come highly recommended. But if you’re after a special gift for the handyman (or woman) who has everything, it could be worth a look.
The heads are drop-forged from 5160 steel alloy that is hardened to a Rockwell hardness of 54–56 HRC. The head weighs 4lb (1.8kg) and has a classic Dayton pattern. The handle is made of straight-grain, premium Appalachian hickory.
That’s if you can, ahem, hack the price. The top-of-theline painted models go for around $450, not including postage and handling from the US. n Go to: www.bestmade.com
There’s a feeling you get when you hold a quality tool, especially when it’s something as simple, hefty and – let’s face it – sharp as an axe. It connects with us in a way that goes far beyond just metal and wood. US company Best Made is looking to tap into that feeling with its range of axes. Founder Peter Buchanan-Smith grew up on a farm in Ontario before his career led him into the world of graphic design. As a designer he worked with some of the biggest names, and even won a Grammy Award for the album artwork on Wilco’s A Ghost Is Born. So it’s no surprise that his tools are also works of art. His axes have attracted high-profile buyers, such as filmmaker David Lynch, and have been hung in the Saatchi Gallery in London.
Swing it at a log or hang it up as a work of art – or both!

SEVEN REASONS NOT TO MISS ARBS It’s the bigg est HVAC&R show in Aus coming to S tralia and it’s ydney next month. We pick out the attractions a must-see t ARBS 2018 .
1 MORE DISPLAYS
THAN YOU CAN POKE A SELFIE STICK AT
Once every two years the attention of the HVAC&R industry in Australia and the Asia-Pacific region centres wholly and solely on ARBS, so everyone is looking to make an impression. It’s a chance for providers of HVAC&R goods and services to show off their wares, for potential customers to look for solutions, and for everyone to do some networking. For the average HVAC&R technician or student it’s also just a great opportunity to get a close-up look at the latest and greatest technology and engineering smarts. And good news for skint students and trainees – entry to the exhibition is free. With more than 300 exhibitors and in excess of 9,000 visitors, this year’s event is forecast to be the largest ARBS to date. Make sure you wear some good walking shoes!
2 PARTY IN THE
PLANT ROOM!
The venue for ARBS 2018 is the International Convention Centre in Darling Harbour, which is worth visiting in its own right – especially to check out the design of the HVAC&R systems. A total of 210 separate air-handling units (AHUs) and fan-coil units (FCUs) have been installed across the ICC, which also features a 400kW solar PV array, a centralised energy plant, rainwater harvesting and extensive CO2 monitoring. Innovative window glazing promotes views and maximises natural light in the pre-function areas. And the distinctive shading was designed using computation fluid dynamics to model the seasonal internal temperature changes. The central plant room contains six high-efficiency centrifugal water-cooled chillers, with a total installed

Feature Anyone who has struggled on a hard-to-reach job might want to hang around for the 10.30am session: Innovative Solutions to Maintenance Access Issues.
In 2016, NDY and Westpac Corporation won the ARBS Project Excellence Award.
This panel discussion will look at how technology in inspection and maintenance is changing the way we access plants, and reducing the risk of injury for FMs and technicians. Entry will cost you $30. For the fridgies, the pick of the talks is on Wednesday, May 9 at 8.30am – The Modern Technician: The future of the refrigeration trade. A panel of experts will discuss what is hindering and helping the uptake of refrigeration apprenticeships and traineeships in Australia, and look at proposed changes to training packages. And if you needed another reason to attend this session, it’s free!

The most popular page of HVAC&R Nation will have a special section at the AIRAH stand. Three carefully selected photos of, erm, less than perfect workmanship, will be up on the wall and under the spotlight for all visitors to poke fun at. So come along, say g’day to the AIRAH team, tell us what you think of the mag and vote for your favourite Lighter Side entry. Leave your details and you’ll go into a draw to win a grand prize. You’ll find us at stall 2211/2229.
BEST IN SHOW
The Industry Awards Gala Dinner is a celebration of the best operators in the business, and sees gongs handed out for Young Achiever, Product Excellence, Software/Digital Excellence, Project Excellence, Outstanding Service & Maintenance Provider, and Outstanding Industry Education/Training. Granted, at $190 a head plus $19 GST it’s not a cheap night out, but it’s a great opportunity to see who’s setting the bar professionally in Australia, and
to make contacts. MC for the evening is Tony Squires, from Back Page Live on Fox Sports and The Fat on ABC, so expect a few laughs as well. The Awards Gala Presentation Dinner is at 7pm on Wednesday, May 9 at the ICC.

GET SMART
Recognising the increasing importance of technology in building management, ARBS has created a new space for 2018: IBTech@ARBS. This is a dedicated precinct within the event where visitors can explore cutting-edge intelligent building technologies and solutions. Building owners and operators, design and implementation experts, product designers and suppliers will come together at the IBTech@ARBS Insight Series to explore what smart buildings of the future might look like, and what threats, challenges and opportunities they could bring. Attendees can interact with smart building technology developers in the dedicated exhibition area and see live demonstrations of industry-specific smart building products and solutions. And, in an Australian first, IBTech@ARBS exhibitors will attempt a live integration by connecting as many devices as possible to the cloud and sharing data. Outcomes of the project will be presented to attendees. n

GOLD-MEDAL PERFORMANCE
Designed by Cox Architecture, the new Anna Meares Velodrome in the Brisbane suburb of Chandler will be a key venue at the 2018 Commonwealth Games. It features a competition-standard 250m timber cycling track, with seating for up to 4,000 spectators. The venue’s mechanical services were installed by Gold Coast-based General Air Conditioning Services, which was established in 2010 by Peter Brunt, M.AIRAH, and Lee Mitchell. Air conditioning is provided to the venue’s gymnasiums, offices and function rooms, as well as critical areas such as data rooms, security rooms and electrical switchrooms, using a wide range of Fantech products. These include EC PowerLine and Multiflow fans, as well as JetVent Series fans to circulate air under the timber track. Fantech also supplied Vacon variable-speed drives for the project. Brunt says fans were selected carefully to meet the project’s stringent acoustic requirements. “Fantech was able to provide invaluable technical support and offer a large range of options and alternatives for consideration,” he says, “resulting in our ability to meet the required standards.” The venue and the HVAC&R system will be put to the test when the Commonwealth Games are held from April 4.

CATHY’S COOL FUTURE
her father’s refrigeration workshop, and in the field, helping with the tools and learning on the job. “My teachers were wonderful, and went the extra mile to show me how machinery worked if I didn’t understand the theory,” she says. “It was the hands-on practical training and beating the boys at their own game that got me through.” Since graduating, Reinecke hasn’t looked back. She continues to work alongside her dad and an uncle in the family business – Blaze Refrigeration. Her daily work includes 200–2,000kg ice machines, commercial refrigeration, and pub and hotel work across NSW. Cathy says her TAFE classmates were very supportive, despite the fact that she was the only girl in her class. She thinks that more young women should consider taking on male-dominated trades, and can do well if they put their minds to it. Her goal is to expand the company in the future and, with her dad’s complete support, take on more female apprentices. Go to www.tafensw.edu.au n

BEIJER REF BUYS HEATCRAFT
As this issue of HVAC&R Nation was going to print, Beijer Ref released a statement announcing that it was set to acquire Heatcraft Australia.
Cathy Reinecke and her family moved from South Africa to Australia after one of her uncles was murdered in their home town of Pretoria. Speaking only Afrikaans, the family faced many challenges as they settled in to their new life in Australia.
“This acquisition is in line with our strategy to also grow outside Europe”, said Beijer Ref CEO Per Bertland, pictured above. “In addition, we strengthen the OEM segment through the acquisition of the Wuxi production plant in China, which in the long term could provide further opportunities to continue expanding our European green technology to the rest of the world to a much greater extent.
In 2014, Cathy began her studies in the Certificate III in Air-conditioning and Refrigeration at TAFE NSW Nirimba. She had already spent a year working in
“We expect that Australia, in particular, will comply with the European directives to phase out environmentally hazardous refrigerants.

“With the acquisition of Heatcraft, we are even better positioned in the market for green technology which we believe will grow significantly.” The purchase price of SEK450 million (Au$70 million) excludes Heatcraft’s operations in New Zealand, which Beijer Ref has chosen to divest on completion for competition law reasons. The sale is expected to be completed in April. Go to www.beijerref.com.au n

BLUE SKY THINKING
A new development in Adelaide’s CBD is now complete and occupied. The 428-bed student accommodation project in Waymouth Street aims to set a new benchmark for green design. It was backed by the Clean Energy Finance Corporation to the tune of $32 million in debt financing. Mechanical services provider D-STAL Electrical was commissioned to carry out the air conditioning installation, which included 35 VRV heat reclamation systems feeding 454 fan-coil units from the ground floor to level 15. “Installing refrigerant pipework from each floor to the rooftop needed extensive planning and patience,” says D-STAL company director Damien Staltari. “The density of floors, issues with space and ceiling height, sealed risers and the congested rooftop meant we had to look for an alternative to traditional jointing methods.” They used Conex Bänninger’s MaxiPro, a flame-free press solution that, unlike traditional brazing, did not require hot works permits. The three-point-press system provided permanent mechanical joints – without the need for a nitrogen purge during the jointing process. The Wingfield branch of Reece HVAC-R supplied the MaxiPro fittings, along with training and certification. Go to www.conexbanninger.com.au n

FUJITSU’S NEW HQ
Fujitsu General Australia has started work on its new national headquarters at Eastern Creek, NSW. The 11,093m2 building will house the company’s head office, Fujitsu General Assist and an 8,500m2 distribution warehouse. The new offices and warehouse will support operational and distribution activities across the Fujitsu General network, nationally. The new building will be 5 star Green Star energy rated. “The development will provide space and resource for Fujitsu General’s continued growth,” says Fujitsu General’s Philip Perham. “The new office will include a Fujitsu General showroom, on-site gymnasium, auditorium and outside green areas.
The design has a 5-star Green Star rating and follows the company’s sustainability philosophy.”

The initial design concept was completed by Sydneybased designers ODCM, in conjunction with Fujitsu General and Vaughan Constructions. The new HQ is set to be completed in December this year. n
Second in the survey was the Ford Ranger ($44,490–$56,490 new), scoring 12 per cent of tradies’ votes. It’s gaining ground on the Hilux too, outselling it in both September and October last year.
OPEN HOUSE AT EBM-PAPST
The Toyota Landcruiser Ute ($60,990–$68,990 new) came in at number three in the survey with 10 per cent of votes. Although the Landcruiser is renowned for being low on frills and big on reliability, the newest models are more refined – the 70 Series Double-Cab won 4x4 Australia magazine’s gong for 4x4 of the year.

HVAC AND RECONCILIATION
The A.G. Coombs group of companies organised for a Boonwurrung elder to perform a welcome to country and smoking ceremony at its corporate head office in Moorabbin, Melbourne, on March 8. The ceremony was to mark the unveiling of a plaque which acknowledges the traditional custodians of the land on which the office is situated. A.G. Coombs has had an indigenous participation policy in place for some time, and in 2016 committed to a formal reconciliation action plan (RAP). The RAP outlines clear, achievable and measurable actions to realise the company’s vision for reconciliation. “The plaque we are unveiling is a small, but symbolic gesture of commitment to our ideal of just, equitable and reconciled Australia,” said A.G. Coombs managing director Russell Telford. n

Legal Speak
WHAT’S IN A NAME? HVAC&R Nation’s legal expert Frank Gambera explains how you can protect one of your business’s most valuable assets: its name. Alongside your expertise and competence, your brand is one of your business’s most valuable assets. Your brand is what people think of when they see your business name – your brand is your reputation. Think of the big players in the industry like Reece, Daikin and Kelvinator. What springs to mind when you see those names? What would happen if a cheeky competitor started a business called Reese? Or Baikin? How would your reputation be affected if someone used a business name almost the same as yours, but was dodgy? You work hard to establish a business and gain an enviable reputation, so you need to protect it.
REGISTER YOUR BUSINESS NAME The Australian Securities and Investments Commission (ASIC) is responsible for the registration, management and administration of business names. If you are about to start a business, or realise you have not registered your business name, then you should conduct a search of the ASIC business name register on the ASIC website. To register a business name, you will need to create an account with ASIC connect. You will also need an Australian Business Number or be in the process of applying for one. The current fees for registering a business are $35 for one year, or $82 for three years. There are ASIC rules that prevent the registration of a business name that is identical or nearly identical to an already registered business name. However, there is nothing to stop the registration of two similar business names. For example, ASIC would not allow the registration of the following business names because they are almost identical: The Awesome Air Con Experts/Awesome Air Con Experts
REGISTER YOUR DOMAIN NAME Your domain name is a key part of your online address and is what people use to find you easily. None of the above steps relate to the protection of your domain name. Domain names are issued by private internet companies and registered by the .au Domain Administration Ltd. You will need to check that your domain name is available before you register it. Registering your domain name does not protect the name itself, it just secures your web URL. This means no one can use a web address the same as yours.
However, it is likely ASIC would allow the following business names because they are similar but not identical: Pete’s Plumbing/Pete’s Plumbing and Heating
REGISTER YOUR NAME AS A TRADEMARK The best way to prevent someone from someone using a similar business name is to register your business name as a trademark. A trademark distinguishes one person’s goods or services from those of another. Registering a trademark provides you with exclusive rights to use, license and sell the mark. A trademark can be a letter, number, word, phrase, sound, smell, shape, logo, picture, movement, aspect of packaging, or a combination of these. Intellectual Property Australia (IPA) is the government body responsible for the management of trademarks and applications to register a trademark must be made online. The IPA website guides applicants through the process. Trademarks are associated with classes of goods, so you must correctly identify all the classes relevant to your business. Class 37 for example, covers refrigeration service and installation, whereas Class 42 covers refrigeration design and engineering. The cost of registering a trademark depends on the application method and how many classes you register under. As a rough guide, it can cost $150–$400 per class. Many businesses use a trademark attorney to ensure their application is successful. A trademark will not be approved if it is not distinguishable from existing trademarks in the same class. If you have a distinctive logo you wish to protect, you can also register it as a trademark with IPA. Many businesses register their name and logo at the same time.
More and more people are turning to the eskimo for independent residential air conditioning advice for consumers 26 | HVAC&R Nation | www.airah.org.au/nation | April 2018
To buy a “.com.au” or “.net.au” web address you will need to have an Australian Company Number or Australian Business Number.
DEALING WITH UNSCRUPULOUS COMPETITORS It’s all very well taking the correct steps to protect your business and make sure you are not stepping on anyone’s business toes. But what can you do when another business encroaches on your brand? If you believe there is a real risk of substantial detriment to you because of the registration of a similar business name, you may be able to ask ASIC to review its decision. The process is explained on the ASIC website. You can also send a “cease and desist” letter for trademark infringement. This is a document sent to an individual or business to stop purportedly illegal activity (“cease”) and not to restart it (“desist”). You should warn the recipient that if they do not discontinue using your registered trademark by a deadline set in the letter, that you may take legal action. Where a cease and desist letter is unsuccessful you should consider seeking legal advice to enforce the trademark through the court process. Legal battles are expensive and time-consuming. Protect your brand and reputation before a competitor starts to interfere with the business success you’ve worked hard to gain. n
