WE'RE STILL IN the first quarter of the year and there's been activity on all fronts in recent weeks, from major acquisitions to the rollout of new technology for RAC technicians. On the financial front, Beijer Ref is set to acquire Heatcraft Australia with the deal likely to be finalised in May. For the bigger players like Beijer Ref it isn't just about organic growth, a little M&A activity is a great way to accelerate market share. In fact, the deal means the Asia Pacific region will now account for 19 per cent of Beijer Ref's global sales. The company made its local intentions clear back in 2015 with the purchase of Realcold and Patton. Even back then the company stated that its objective is to grow faster than the market. Meanwhile, technicians have made the move to smart card technology which is likely to become the new norm as the year progresses. While the Australian Refrigeration Mechanics Association (ARMA) and the Australian Refrigeration Association (ARA) were the first to rollout the technology to its members (see story page 6), the Australian Refrigeration Council (ARC) has revealed its plans to also make the move to smart cards for technicians right across Australia. Another exciting development has been the release of new research by Stanford University in the

US and the University of Technology in Sydney. The researchers have created specially designed fluid-filled roof panels to help make air conditioning significantly more efficient (turn to page 28 for the full story). If that isn't enough excitement for one issue, then you are in luck! CCN has launched its 2018 HVACR Leadership Awards with the support of ABB, Daikin, Innotech, Toshiba and Totaline. Everyone is invited to nominate. Simply go to www.climatecontrolnews.com.au/awards. This year for the first time ever, the awards presentation will be held in Melbourne on October 11, 2018. Interestingly the year CCN Live heads to Melbourne, the ARBS Exhibition comes to Sydney. The countdown has officially begun with ARBS 2018 only four weeks away. That's right! We get to maintain the pace for another quarter. ✺

News LEFT: Here is the front and back of the smart card which lists the cardholders credentials.

HVACR trade goes virtual THE AUSTRALIAN REFRIGERATION MECHANICS ASSOCIATION (ARMA) AND THE AUSTRALIAN REFRIGERATION ASSOCIATION (ARA) HAVE JOINED FORCES TO CREATE A NATIONAL SMART CARD FOR USE BY THE ENTIRE HVACR INDUSTRY. The smart card provides prospective employers with instant access to a technician's trade qualifications and licensing credentials. ARMA CEO, Kim Limburg, said users simply scan the QR code to check credentials. Limburg said it will overcome the problem of unscrupulous RTOs offering short courses in refrigeration and air conditioning which have been "dumbing down" the trade. "Only technically competent individuals will gain access to the ARMA smart card because we have a stringent vetting process," she said. "Currently consumers have no access to information correctly advising them who is trade qualified to carry out refrigeration and air conditioning work but now they do. "Cardholders retain control of who can access their information. When an employee leaves one

CLIMATECONTROLNEWS.COM.AU

company and commences work for another the employee simply changes authorisation. "Licence holders throughout Australia will have a single card which allows regulators, agencies and industry bodies instant access regardless of which state or territory they work in and regardless of different legislative requirements." While the smart card is currently available to ARMA and ARA members it is ready to be rolled out to the entire industry. However, to manage and administer the smart card effectively both groups believe a National HVACR Council needs to be established. "The role of the council is to guide and coordinate the HVACR industry in Australia on behalf of all levels of government and industry and across all sectors," Limburg said. "The industry desperately needs greater collaboration and coordination to successfully transition to low GWP refrigerants. "The regulatory structure of the industry, to date, has been solely focused on controlling the emissions of synthetic refrigerants. "We need to guide so many other areas of the industry like standards, training, education and innovation policy." Limburg said Australia's current licensing body, the Australian Refrigeration Council (ARC), does not function as a body for coordination or change management in the HVACR industry.

"Despite the importance of the industry and the opportunity for improvements very little federal leadership has been shown beyond emissions reduction," she said. "The impact of transitioning from high GWP refrigerants to low GWP refrigerants cannot be understated, it is a huge task. "To accomplish this the HVACR industry requires leadership across all areas of the industry. It is no longer just about emissions, there has been a fundamental shift. "This is why we need a National HVACR Council and a nationally consistent skills based licensing program for the HVACR trade." A spokesperson for the ARC said there is already close collaboration across industry. He said the ARC delivers one national, skillsbased licence scheme to over 87,000 individuals and businesses Australia-wide. "The success of the scheme, and of the campaigns and initiatives we deliver, is due to broad industry support, as well as the ARC's collaborative foundation – the ARC's RAC industry board and membership which is made up of all mainstream industry associations. "This promotes high-level collaboration in all aspects of the sector." He said in the past 18 months, ARC has implemented a raft of new initiatives including the Green Scheme accredition program, a RAC advocacy campaign and icareers video sent to all secondary schools Australia-wide plus working with ASQA to close down sub-par training courses, just to name a few. ✺

ARC SMART CARD PLANS The Australian Refrigeration Council (ARC) also has plans to introduce ‘smart card’ technology for the licence cards provided to technicians. An ARC spokesperson told CCN that the new smart card technology would be used in conjunction with a free phone app. “The smart card will not only identify technicians as being licensed, it will also enable improved functionality, convenience and access to valuable technical resources,” he said. Other benefits include real time records, simple identification for consumers as well as improved safety and compliance.

EEC supports energy saving tax deduction A NEW FEDERAL Labor policy that gives an immediate tax deduction to businesses that invest in energy saving equipment will help slash energy bills, according to the Energy Efficiency Council (EEC). Under Labor's "Australian Investment Guarantee" policy, businesses will be able to immediately deduct 20 per cent of an investment in eligible depreciable assets over $20,000, including those that lower energy use and improve energy efficiency. EEC CEO Luke Menzel said the policy was timely and recognised that Australia is in the midst of a massive economic transition that will require businesses to use energy more efficiently and productively. "We know from a raft of reports over many years that Australian businesses use more energy than their competitors overseas, and Aussie manufacturers are at the back of the pack when it comes to energy productivity," he said. "That was fine, even five or six years ago. But now manufacturers and other large energy users are caught in a pincer movement between rising electricity and gas prices. And in some cases these cost pressures are threatening jobs and business viability." Menzel said the good news is that businesses can quickly slash energy bills with ambitious energy upgrades that bring operations in line with our global competitors. The tax deduction was announced by Labor's energy spokesperson, Mark Butler. He said the Australian Investment Guarantee is easily accessible to all businesses and will operate through the tax system, minimising compliance costs and maximising the benefits to business, workers and the climate. "From small businesses upgrading refrigeration systems, to the largest manufacturers upgrading smelters, Australian businesses will receive permanent, targeted tax support to modernise and cut their energy bills," Butler said.

Beijer Ref to acquire Heatcraft Australia Heatcraft’s wholesale gas facility in Sydney’s west.

BEIJER REF IS set to acquire Heatcraft Australia, a wholly owned subsidiary of Lennox International, in a deal worth around $90 million. The transaction is expected to be completed in May. "The deal is worth around $90 million, which values Heatcraft Asia Pacific at approximately nine times earnings before interest, tax, depreciation, amortisation and rent," according to media reports. "Lennox will earn a bit more from the deal by separately selling Heatcraft's eight-hectare distribution hub in Milperra in Sydney's southwest for around $50 million."

Announcing the deal, Beijer Ref said arrangements are in place to immediately dispose of Heatcraft's New Zealand operations to address any competition concerns. Heatcraft Australia also has operations in China and Singapore and the deal also includes just over five per cent of shares in Thai compressor manufacturer Kulthorn Kirby. Beijer Ref said the acquisition is in line with its strategy to grow outside Europe. The acquisition means that the Asia Pacific region will now account for 19 per cent of Beijer Ref's global sales. Lennox said the sale of its Heatcraft business in Australia and Asia is part of a streamlining of its refrigeration business and plans are underway to also sell its South American operations to an unnamed buyer. Heatcraft has more than 300 employees in Australia. ✺

US President Donald Trump said the tariffs will protect US jobs.

Trump tariffs hit HVACR industry THE AIR-CONDITIONING, HEATING, AND REFRIGERATION INSTITUTE (AHRI) HAS WARNED THAT TARIFFS ON STEEL AND ALUMINIUM WILL NEGATIVELY IMPACT THE HVACR INDUSTRY.

IN A LETTER to US President Donald Trump, AHRI said it was disappointed by the decision to introduce a proposed 25 per cent levy on all steel imports and 10 per cent levy on aluminium. AHRI president and CEO, Stephen Yurek, said it will be injurious rather than helpful to

members of the US-based group, which represent manufacturers of heating, air conditioning, commercial refrigeration and water heating products and equipment. "As major users of steel and aluminium, we have been proactive in explaining to the administration that the HVACR and water heating industry would be negatively impacted by an increase in tariffs, as would the consumers that rely on the products we manufacture," Yurek said. "While we have been pleased with the Trump Administration's enthusiastic support for manufacturing, we believe this step to be injurious, rather than helpful, to our efforts to increase American manufacturing and create jobs." President of the Peterson Institution for Inter-

national Economics, Adam Posen, described the tariffs as "straight up stupid". "Steel is just a tiny input in US gross domestic product (GDP) terms which is why it's so crazy. You mess up your entire trading system for an industry that has a total of 80,000 jobs," Posen said. 2015 census data showed roughly 140,000 Americans were employed in steel mills, contributing $36 billion to the national economy. By comparison, steel-consuming industries, which experts believe will be hardest hit by the tariffs, employ 6.5 million Americans and add about $1 trillion to US GDP. The US accounts for about 0.8 per cent of Australia's steel exports and about 1.5 per cent of aluminium exports. It is an industry worth about $545 million to Australia's economy.

Record turnover takes staff numbers to all-time high

THE FAN AND motor manufacturer Ziehl-Abegg posted growth of around 12 per cent in the year 2017. Turnover rose from $768 million to $856 million and reaching a new record high on the number of employees. Ziehl-Abegg CEO Peter Fenkl said the growth in sales was worldwide with some countries posting increases in the double digit percentage range. "Our expectations have been significantly exceeded in Asia as well as in North and South America," he said. "This year we will again be

launching products that will set new records for energy efficiency, as well as investing in the global production and service network." A year ago, Ziehl-Abegg employed 3,550 people worldwide, now that figure is 3,900. Ziehl-Abegg has also improved and expanded its production capabilities. In 2017 the company invested a record $68 million. While ventilation technology (fans) and drive technology (elevators, medical technology) each posted double digit sales increases, the automotive division is lagging behind expectations. â&#x153;ş

Briggs said the Rising Star category uncovers the high performers within the industry. He said awards programs can help motivate young people to strive for even more. To recognise diversity within the HVACR industry, Briggs said it is important to have a dual award that recognises young men and women individually.

Presenters will discuss the importance of attracting a diverse range of people into trades training and outline what is required to support their successful completion and ensure the level of skill required to meet future workforce needs. A tour is also planned for the Barangaroo South District Cooling site following a presentation on the project from 'concept to operation'. A significant contributor to achieving its carbon positive goal is the district cooling system that provides chilled water to all types of buildings within the development. The presentation will explore challenges including laying the foundations of a workable sustainability strategy; the precinct wide cooling design concepts and strategies employed; integrating the detailed design of the commercial building's cooling systems; and the transition from construction to the required operating performance. The tour covers Barangaroo South, a landmark development on the shores of Darling Harbour and one of only 18 projects globally to be a part of the Clinton Climate Initiative's C40 carbon positive development program. Another presentation that is likely to attract a lof of interest is entitled Net-Zero Buildings: Australia's vision for a carbon positive future. Join GBCA, NABERS, the Department of Environment and Energy, and AMP Capital to discuss the trends for net-zero buildings in Australia and what this means for the HVACR industry.

A tour is planned for the Barangaroo cooling plant.

Day three presentations include Big Data – Is it hype or the future? This session will explore 'big data analytics – academic or real world (focus on analytical methods)' as well as 'data collection – best practice/data integrity' and 'data management and artificial intelligence'. One topic that has generated a lot of interest over the past 12 months is Legionnaires' disease. Recent outbreaks of Legionnaires' disease in Sydney and Melbourne CBDs have highlighted the need for interventions to firmly address building services design and maintenance practices. A session is planned which will describe systems most at risk and outline control mechanisms proven to be effective. The changes to regulations including the need to apply risk management principles will also be covered. Increased awareness of the impact of refrigeration and air conditioning on the environment continues to change the way industry think and act when making decisions for the future. A special presentation is planned to provide the audience with a clear understanding of how HFOs combined with diverse refrigeration architectures are already positively impacting the industry, through improvements in energy efficiency, refrigerant charge/leak reduction, total cost of ownership and reduced overall environmental impact. Research into PV cells driving domestic airconditioning units will be presented on day three of ARBS. The presentation will explore the project 'Stand-alone Solar Powered Air-Conditioning System' which examines the feasibility of running a system with renewable energy that is generated on-site. The results will be a good indication of what the future may hold for PV powered air conditioning systems, for both small-scale (residential and light commercial) and largescale applications.

CCN: Before we begin can you tell us a little about Hitachi's history in the Australian market? WALSH: It has been almost 10 years since Temperzone became the sole distributor of Hitachi Air Conditioning products in Australia and New Zealand. Prior to Temperzone taking over distribution, Hitachi Air Conditioning had been in the Australian market for about 25 years. CCN: How does the partnership work? WALSH: The relationship between Temperzone and Hitachi has perfect synergy. It provides a wide scope of products and solutions to the Australian and New Zealand market place via Temperzone's large network of sales offices and warehousing through branches in

CLIMATECONTROLNEWS.COM.AU

Sydney, Melbourne, Brisbane, Adelaide, Perth, Auckland, Wellington, Christchurch, and dedicated distributors in Newcastle and Hobart. It means that as a business we can offer a wide range of products from high wall split systems, ducted split systems, rooftop package units, to water cooled and chilled water products. Our range extends from a 2.5kW Wall mounted split system to a 1400kW Chiller and everything in between. It is one of the most comprehensive ranges of air conditioning product available in Australia and NZ. It works particularly well when we can supply both brands in a single project. A great example of this are warehouse and administration projects where Temperzone rooftop units are used in the warehouse while Hitachi VRF is used in the administration

areas, or projects using Temperzone chilled water fan coil units with Hitachi screw chillers. CCN: So what can we expect in the year ahead? WALSH: We have an extensive range of new products being released and we are also focusing on marketing and support tools like the development of new mobile applications for both our residential and commercial customers. New product releases in 2018 will include: a completely new VRF range, a new R32 high wall split range, new R32 mini cassette and ducted units, a completely revised modular chiller range and new inverter ducted systems. On top of this there are a range of new controls for virtually all the equipment. First up is Hitachi's new Set free sigma series. The new VRF range boasts increased single module capacity with the largest single module at 24HP. We have increased and improved the range of indoor units including several new ducted models. Additional features include improved EER and inverter control, higher maximum pipe lengths and ambient temperature than the current models.

The eco touch remote control unit offers display in 12 different languages.

New lineup features AirFlex technology FROM NEXT MONTH Mitsubishi Heavy Industries Thermal Systems Ltd., a group company of Mitsubishi Heavy Industries, Ltd. (MHI), will progressively launch a total of 274 new models in its two packaged air-conditioner series – the ultra-energy-efficient “ExceedHyper” series and the HyperInverter series. All models adopt the environmentally compatible R32 refrigerant and the lineup of models featuring "AirFlex", the industry's first function suppressing the unpleasant draftiness typically felt when air from the room unit blows directly on a person, has been significantly expanded. The highly acclaimed "eco-touch" remote control unit has also been enhanced to deliver even higher performance. In the ExceedHyper series, a lineup of 109 models in the 1.5-6 horsepower (HP) range will be offered, excluding the single-unit 3-6 HP models launched in May 2016. The 16 models in the "FDT Series" of indoor ceiling-mounted units with four-way air outlets can now accommodate AirFlex panels. When these innovative panels go into operation, wings emerge to prevent air from directly blowing on

the people in the room, thereby elevating the level of comfort. In addition, when the air-conditioner is operating, integrity between the panels and the indoor unit is maintained, easing any oppressive sensation, and when the air-conditioner is turned off, the panels retract into the indoor unit to maintain a beautiful appearance. The HyperInverter series will consist of 165 models, spanning a range from 1.5 to 6 HP and all newly featuring the R32 refrigerant. All ceiling-mounted units with four-way air outlets can be equipped with AirFlex panels. The 5 and 6 HP outdoor units have been scaled down to the same dimensions as the Company's 4HP models (W970×H1300× D370mm). The "eco-touch" remote control unit offers display in 12 different languages. Performance has also been enhanced to accommodate the forthcoming new models in the FDK Series of wallmounted units. ✺

Look to the sky beyond

smart rooftops SPECIALLY DESIGNED FLUIDFILLED ROOF PANELS CAN HELP MAKE AIR CONDITIONING SIGNIFICANTLY MORE EFFICIENT, ACCORDING TO NEW RESEARCH BY STANFORD UNIVERSITY AND THE UNIVERSITY OF TECHNOLOGY IN SYDNEY.

THE PANELS WORK like solar water heaters, except that they extract heat from the flowing fluid, rather than adding it. This has only been made possible through the development of new, highly reflective materials that allow more heat to be taken out of the fluid than finds its way back in, even in the heat of a sunny day. According to researchers, led by Stanford University's Eli Goldstein, the panels, when integrated into an existing air conditioning system, can use 20-50 per cent less power to deliver the same amount of indoor cooling. This in turn could help smooth out demand peaks on the electricity grid in summer, cut energy bills and reduce the risk of blackouts.

For several years, the Stanford and UTS researchers in Sydney have been trying to design smart roof materials that help dissipate heat from air conditioning systems more effectively. Conventional air conditioning systems get rid of their heat by simply venting hot air from the system's outdoor fan unit. But the new design adds an extra step, using a heat exchanger to pass the normal refrigerant heat into the fluid, which can be either water or glycol. This fluid then flows into the rooftop cooling panels so the heat can be dissipated into the sky. The previous problem with this approach was that on hot, sunny days – when air conditioning is needed the most – the sun makes the fluidfilled panels heat up, rather than cool down. This problem has only been solved in the past three years, with the design of super-reflective surfaces that can repel 97 per cent of the incoming solar energy. Nearly all synthetic and natural surfaces absorb at least five per cent of incident solar heat. Even the best white roof paints typically absorb more than 10 per cent of the sun's heat. The best performing surface is a shiny, flawless layer of silver, but that doesn't last very long in outdoor conditions. But what if we can protect the silver and maybe even improve its reflective performance by placing it under a layer

that also helps to reflect solar energy? Three research groups came up with possible solutions, two involving plastic coverings for the silver and the third involving a complex layering of different oxide materials. At UTS, the approach involved using many layers of two different plastics, placed on top of the silver. The resulting material reflects 97 per cent of the incident solar energy, repelling the sun's heat so effectively that the fluid inside cools down, even on a hot day. As the new Stanford research confirms, these super-reflective surfaces can perform a neat trick – getting the rooftop to

lose heat during the day in the same way it does on a clear night. On clear nights, upward-facing surfaces can drop to several degrees below the ambient temperature because their heat dissipates high into the sky. The new super-cool roof panels do the same in the daytime as well. For example, they can condense dew well after sunrise even though the outdoor air temperature is above the dew point. The panels can easily be retrofitted onto existing air-conditioning systems, ultimately saving money because of the reduced energy use. By modelling their system's performance, the Stanford researchers calculate that the panels could reduce air conditioning costs by 21 per cent for a typical two-storey building in the sunny climate of Las Vegas. These hybrid systems could become commonplace, combining indoor units with the new panels shedding the heat upwards into the sky. ✺

CLIMATECONTROLNEWS.COM.AU

"The wind-free room air conditioner addresses both of these issues together, providing unparalleled cooling comfort, while guaranteeing optimum energy efficiency. "Customer centric innovation lies at the core of our brand promise and this product pivots around this very approach. The new technology is especially designed to cater to Indian consumer's specific needs and preferences, given the severe climatic conditions here." The new lineup provides ambient condition by maintaining comfortable room temperature using Wind-Free cooling technology to gently disperse cold air through 9,000 to 21,000 micro air holes. A two-step cooling system, which first lowers temperatures in Fast Cooling Mode and then automatically switches to Wind-Free Cooling Mode, creating 'still air' once the desired temperature is achieved. This approach also reduces energy consumption by up to 72 per cent compared to Fast Cooling mode.

The unique product architecture of this range of air conditioners also contributes to its superior cooling performance. The upgraded structure's wider inlet allows for more air to be drawn in at once, while the optimal width and angle of the outlet ensure that air is cooled and expelled faster, farther and wider to reach every corner of the room. â&#x153;ş

The CSH.6 compact screw compressors provide customers with reliable planning security in response to the European Ecodesign Directive.

CSH version for high efficiency COMPRESSOR SPECIALIST BITZER showcased its new compact screw compressors which meet the European standards for liquid chillers. The new BITZER CSH.6 series is designed for highly efficient air-cooled liquid chillers suitable for operation with R134a or the HFO/HFC blends R513A and R450A as well as the HFO refrigerants R1234yf and R1234z(E). The compressor specialist is expanding its service range in the field of compact screw compressors: as a variation of the proven CSH.5 models, the CSH.6 series is designed for use with lowGWP refrigerants and optimised for the ambient temperature profile specified by the Ecodesign Directive for liquid chillers. It boasts exceptional refrigerating performance and impressive seasonal energy efficiency ratios (SEER), helping OEMs to comply with legal re-

quirements. The application limit of the CSH.6 series is tailored to air-cooled liquid chillers for comfort air-conditioning and is characterised by adjusted oil management, economiser operation in full-load and specially adapted Vi in part-load operation, according to Bitzer's product manager for screw compressors, Dirk Schlehuber. "We've developed the CSH.6 specifically for applications with air-cooled liquid chillers for airconditioning applications, which have been subject to stringent requirements in terms of minimum energy performance in Europe since January," he said. "The CSH.6 series allows our customers to continue building cost-effective liquid chillers which meet statutory (tier one) seasonal efficiency requirements without having to resort to costly use of frequency inverters." ✺

THE AIR-COOLED QUANTUM Series from Engie Refrigeration can be optimised for any cooling scenario. The chillers feature integrated free cooling and has a refrigeration capacity of up to 1,800 kilowatts. The air-cooled Quantum chillers can also operate using either R-134a or R-1234ze as refrigerant. Specially for use in hot countries and areas where low noise emissions are crucial, the refrigeration specialist also equips the chillers with new condenser coils for chilling the refrigerant. The solution really shows its strengths in locations where outdoor temperatures are high. The recooling capacity has been optimised overall and ensures optimum cooling output even where temperatures constantly remain high. Quantum chillers are designed to fit the same footprint as earlier versions in order to keep the required installation space the same. At the same time, cooling output is considerably higher. With the changes made to the condenser, the internal fans can run at lower speeds and power. This saves on running costs but also reduces noise emissions compared with the standard version. The fan's reduced power also means an indirect reduction of carbon emissions. ✺

"We will continue to pursue the development of other low GWP alternatives," he said. "We believe R-134a will continue to provide the best combination of availability, cost, performance and safety for many years to come. "The ability to convert our R-134a chillers to other refrigerants provides owners and facility managers even greater options that ensure the full useful life of these chillers." ✺ Visit http://www.carrier.com.sg.

CONCERNED ABOUT THE RELIABILITY OF ITS CHILLER PLANT THROUGH THE PEAK SUMMER PERIOD, THE TEAM AT WESTMEAD HOSPITAL IN WESTERN SYDNEY DECIDED TO REVIEW REDUNDANCY OPTIONS.

KNOWING A RISK management strategy was necessary, the engineering team called Active Air Rentals and asked for a design and construct solution. With approval for the project given on December 16, 2017, the Active Air project team got straight to work, ensuring a backup system was in place before Christmas. Installing 3,500kW of air-cooled chiller plant was a big ask, added to that was the need to supply temporary power to operate the system. Five chillers, along with four generators, a custom-made switchboard and multiple sets of 240mm2 power lock cables were required to get the job done. Active Air senior project manager, Jonathan Towe, was charged with planning and organising the logistics.

"The small footprint which we had to work with onsite meant that craning in equipment and setting it up was tight," he said. "With upwards of 12 truck and semi-trailer movements, a traffic management plan had to be devised to allow for the transportation and positioning of equipment. "We had people at five different points along the four-way intersection managing the situation and allowing for truck access. A 300m reversing path was also required to allow the trucks to turn back after making their deliveries." With the crane lifts and positioning in progress outside, mechanical plumbers set about cutting into the existing chilled water system. To accommodate chilled water from the tem-

porary plant, 300mm diameter stainless steel pipe ran through the plant room and the adjacent wall where a set of custom-built headers were installed to accept water from the chillers outside. Once the cranes and transports retreated, the 100mm flexible hose used to connect the chillers to the headers was laid out. A team of electricians then began running out the 240mm2 cable sets that would be used to connect the chillers, switchboard, splitters, and generators. The temporary system also required a certain amount of fine control; accepting communication over RS485 from the building management system (BMS) to the panel. This allowed for managing generator starts, machine rotation and general step control of the chillers to meet the combined plant demand. Once in a position to commission the machines, water flow and pressure drops were balanced across vessels to ensure that all machines had adequate flow and could contribute to the building system effectively. This was achieved by using a combination of ancillary pumps and balancing valves.

The solution was commissioned by December 22 â&#x20AC;&#x201C; just four working days after work orders were received. What had begun as a 'just in case' exercise quickly became an integral piece of the building system as Sydney experienced one of its hottest summers on record. The chillers and generators were put to the ultimate test, running effectively through the heat to help ensure the building plant was able to maintain

chilled water supply temperatures through peak load times. "The [Active Air] installation team are to be congratulated for their assistance in providing excellent service and advice that enabled this critical piece of infrastructure to perform exceptionally well during very testing conditions," according to David Dobson, WSLHD senior project manager capital works, Program Management Office (PMO). â&#x153;ş

working together with artificial intelligence systems and machines. This is not only an extension of the 'smartÂ˛' strategy, but also strives to enable products, machines, processes and systems to be loaded with awareness, cognition, understanding and decision-making driven by big data and AI. This will bridge the company's various unique advantages in products and industrial layout, pushing its practices in manufacturing and living to new heights, as well as bringing users into a 'ahead of life' environment. Smart manufacturing is more than just introducing robots and building unmanned factories. Previously, all R&D, supply chain, manufacturing, logistics, sales and after-sales services, including consumers, were fragmented in the manufacturing field. Today, smart manufacturing is developing

ways to change this fragmentation and interconnect all processes, based on the analysis and flow of big data. As a world-leader in consumer appliance technology, HVAC, robotics and automated systems, and intelligent supply chains (logistics), Midea manufactures and sells over 300 million household appliances globally each year. Interconnecting all its manufacturing processes is a daunting challenge. After almost three years of production standardisation and digital transformation, the Midea Group has successfully developed whole value chain software, thereby essentially achieving the "One Midea, One System, One Standard" global collaborative production platform. Based on this, Midea, partnering with the world's leading robotics company KUKA, plans to deepen R&D and innovation in big data and AI technologies to gradually launch automation and business solutions adaptable to various types of complex production scenarios, and lay a solid foundation for furthering the vision of human-machine collaboration via smart manufacturing. According to Wilfried Eberhardt, KUKA AG chief marketing officer, "We see a future in

which humans and machines work hand in hand to make life easier". The need to build an industrial internet has become a global consensus. According to statistics provided by IoT Analytics, the market scale of the Industrial Internet, as of 2021, will reach $2 billion. Midea enjoys incomparable advantages by having, and running, its own whole value chain. Based on its "One Platform, One Standard" strategy, Midea has created an excellent operation in the whole value chain, which fully integrates powerful R&D capability, response to orders, planning capability, flexible manufacturing, purchasing capability, quality tracking, logistics capability and customer service and installation, thereby achieving end-to-end collaboration. This digital-driven platform has realised flexible customisation of C2M, platform development, module combination and digital processes for production, smart logistics, digital marketing, smart service and other profound changes, according to Midea's CIO, Simon Zhang. "The true Industrial Internet is built upon the end-to-end collaboration of the R&D end, production equipment end, supply chain end, business end, logistics end and the user end, which

makes 'Zero' inventory production, 100 per cent logistics tracking and C2M customisation possible," he said. "Midea Industrial Internet has set a solid foundation for this prospect," Zhang said. Currently, the existing cloud platform offers flexible solutions for multi-layer processing and complex processing, and is capable of supporting the production and operation of more than 10,000

“THE INDUSTRIAL INTERNET WILL BE WORTH $2 BILLION BY 2021.“ - IOT ANALYTICS

products across 40-plus bases worldwide, through the collaboration of software and hardware. "The majority of smart household appliances currently on the market simply transplant product operation onto a mobile phone. But Midea believes the meat of real human-machine collaboration is carrier-free," according to Dr. Xu, vice president of the Midea Corporate Research Centre.

To address this, Midea has invested almost $20 million annually to build the largest AI team in the household appliance industry, to study indepth how to get rid of the carrier between human and machine. Some studies have yielded fruit: the large-scale deep learning computer platform, developed and designed by Midea, has been able to accurately identify the style of finished dishes in Chinese cuisine. Meanwhile, through AWE, Midea will release a number of AI products and applications, such as smart cooking robots, AI refrigerators and smart new retail. General manager of the Midea Robotics Company, Olaf Gehrels, said the company will not be limited to the field of manufacturing – robotics will become important parts of logistics, medical care and even the Smart Home. With the aid of humanmachine collaboration, Midea will upgrade its smart household appliances to smart home appliances, allowing it to leapfrog its portal-based rivals. As it marches towards its 50th anniversary, Midea's human-machine collaboration strategy isn't just a technology-driven transformation, it is a blueprint which revolves around the ideas of 'leading products, efficiency-driven, and globally-operated'. ✺ CLIMATE CONTROL NEWS APRIL 2018

Brazing machine delivers the perfect flame CASTOLIN EUTECTIC HAS LAUNCHED NEW REVOLUTIONARY BRAZING EQUIPMENT UTILISING ELECTROLYSIS, WHICH OPERATES WITHOUT GAS USING WATER AS FUEL. THE CASTOLIN DYOMIX OHM 2.4 is born from a collaboration with Bulane, a French company which has patented the dyomix technology. With CleanTech dyomix it is possible to easily produce a clean high-performance fuel from the oxygen and hydrogen naturally present in water, with no storage requirements. The flame born in this process burns at more than 2500ºC, and is particularly suitable for refrigeration and heating specialists, plumbers and for any other professionals using a flame in their daily work. Compact, efficient and safe, the dyomix electrolysers have now been miniaturised to be used directly on site. The equipment was designed to be easy to use, lightweight and portable: just switch on the machine, plug it to a socket and start brazing (Plug and Braze).

By choosing Castolin dyomix OHM 2.4, users simplify their logistical constraints, reduce the level of risk in their daily activities and have a perfect flame onsite, at all times. The new AutoFlam OH torch has also been developed for full compatibility with the dyomix technology. Its unique design and swivel connector at the torch inlet make it extremely ergonomic, lessening musculoskeletal disorders (MSD). Its double action flame arrestor is directly built into the handle, ensuring perfect safety throughout the use of the torch. The materials used are compatible with the oxy-hydrogen gas, making for a very sturdy, light and perfectly balanced AutoFlam OH torch.

vironment concerns hitting the spotlight. The dangers of poor IAQ in a commercial building aren't difficult to spot as they take a physical toll on its inhabitants. There are four categories of side effects that facility managers and administrators should be aware of, according to the US Environmental Protection Agency: Acute: Immediate reactions like headaches, coughing or congestion are elicited within 24 hours from exposure to chemicals, bacteria or excessive moisture. Chronic: Long-term respiratory issues attributed to unchecked threats, such as asbestos. Performance: Drop in productivity and performance tied to shift in temperature, humidity or lack of ventilation. General discomfort: Noticeable irritation brought on by changes to consistent settings. Routine HVAC maintenance can help technicians identify issues with equipment before these threats pose a danger to the workforce. IAQ risks change drastically in a laboratory setting, despite the fact they may seem miniscule at first. In vitro fertilisation (IVF) facilities, for example, need to exercise exceptional control

of this variant if they want to continuously replicate successful results, Vitrolife reported. Pollutants like carbon monoxide, nitrous oxide and sulphur dioxide can rest on surfaces for extended periods of time and harm embryos they come in contact with. Any high-functioning lab will utilise a clean room but between the location of the commercial building – cities present more dangers – and the variety of HVAC systems that can be used, threats can slip past. The potential here, though, could significantly damage the reputation of the facility. Tools like the testo 440 are helping to keep both settings clean and safe. This is done by providing technicians with the instrument they need to accurately identify any changes in key metrics like temperature and relative humidity, K-factor, air flow and pitot tube velocity. The data can then be uploaded to a computer and analysed to spot any concerning trends.

Montreal Protocol

Australia’s atmospheric monitoring station.

Protecting the ozone layer:

Three decades of progress 2017 MARKED THE 30TH ANNIVERSARY OF BOTH THE MONTREAL PROTOCOL AND ACTION IN AUSTRALIA TO PROTECT THE OZONE LAYER. CSIRO HONORARY FELLOW, DR PAUL FRASER, REFLECTS ON THREE DECADES OF PROGRESS.

N 1974, A landmark paper appeared in the journal Nature, describing how increasing concentrations of chlorofluorocarbons (CFCs) in the atmosphere could potentially destroy the life-sustaining stratospheric ozone layer. This paper inspired me and set my career-changing research path for many years to come. It highlighted the need for quality atmospheric monitoring of ozone depleting substances and this, together with carbon dioxide-induced climate change research, were the pivotal issues leading to the establishment in 1976 of Australia's atmospheric monitoring station at Cape Grim, Tasmania. Over the past 30 years, there have been dramatic improvements in our capacity to accu-

CLIMATECONTROLNEWS.COM.AU

rately measure atmospheric concentrations of a variety of greenhouse and ozone depleting gases. At various times the introduction of new, CFCreplacing industrial gases – hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) – began before there were techniques to measure their impact on the atmosphere. We were fortunate and, as it turned out, far-sighted, when we established an archive of pristine air samples at Cape Grim in 1978, that continues through to today, enabling CSIRO to determine the complete atmospheric history of these new species, leading to accurate estimations of their environmental impacts. As a result, we have been able to identify a number of environmental issues and provided

policy makers with evidence to justify prompt policy action. We established, for example, that HFC-23 (CHF3) appeared in the atmosphere long-before its initial use in industry (refrigeration) and was growing at rates that could not be explained by known sources. This led to the discovery that it was being created inadvertently as a by-product of HCFC-22 (CHClF2) production (a widely used refrigerant) and, as a result, governments and the United Nations were able to act to reduce, capture and destroy these emissions. So, what can the current atmospheric readings tell us about the effectiveness of what we have done globally and in Australia? Encouragingly, since the introduction of Montreal Protocol restrictions on CFC production, atmospheric CFC concentrations have declined at a rate that suggests a very low level rate of residual emissions. As a result, the ozone hole is on track to be closed as predicted by late 2050s. Global concentrations of HCFCs are increasing, but at a declining rate, that promises a halt in their growth over the next decade, followed by a predicted decline.

Montreal Protocol

Global concentrations of HFCs are increasing rapidly leading to their inclusion in the Montreal Protocol, which will curb their production, the fastest proven route to stabilising their atmospheric concentrations. As a result of where Cape Grim is located, 300km south of the major urban source region of Melbourne, about 15 per cent of the time we can assess the emissions of CFCs, HCFCs and HFCs from the Melbourne area. This is a useful indicator for what is happening across Australia. The data shows that emissions of CFCs and HCFCs are decreasing and emissions from HFCs have flat lined despite the size of the bank increasing. This clearly shows that equipment today is far less leaky than in the past and attempts to improve the service industry through licensing and other actions are clearly working. This model of industry/science collaboration has been the linchpin for success in ensuring good science and effective policy. Australian industry has actively supported the research at Cape Grim both with financial contributions of over $1 million and in providing detailed information (some of which was very commercially in confidence) on production and consumption processes. Industry also actively engaged with the scientific findings and initiated changes as a result – sometimes well in advance of government policy. Governments, industry and science began working together when there were only model calculations of a potential problem and before there was direct evidence of an issue. This early action, based on the "precautionary principle", was fundamentally important in taking prompt action to fix the ozone problem before it was dire. The data that we produced in the past and today helps both government and industry continue to take action to reduce emissions of ozone depleting and greenhouse gases. ✺ ABOUT THE AUTHOR Dr Paul Fraser researched at CSIRO issues of ozone depletion and climate change from 1974 until he retired in 2015. He, and the atmospheric monitoring station he helped establish at Cape Grim in Tasmania in 1976, have been pivotal in understanding both global and regional emissions of ozone depleting and synthetic greenhouse gases. He is held in extremely high regard in the international scientific community, receiving the US EPA Ozone Protection Award in 2002, the Nobel Peace Prize as a member of the IPCC in 2007, and a UNEP Science Leadership Award in 2017. He is still very active in research as an Honorary Fellow at CSIRO.

Closing the Hole:

A 30-year retrospective on refrigerant policy ONE MAN THAT HAS BEEN ON THE FRONTLINE OF CLIMATE CHANGE POLICY ISSUES FOR THE PAST 30 YEARS IS STEVE ANDERSON, WELL KNOWN TO READERS AS THE FORMER EXECUTIVE DIRECTOR OF REFRIGERANTS AUSTRALIA. HE REFLECTS ON THE GROWING PARTNERSHIP BETWEEN INDUSTRY AND GOVERNMENT.

OVER THE PAST 30 years, the Australian Government – in close collaboration with industry – has developed world leading initiatives on refrigerant policy covering both ozone depletion and climate change issues. However, initial Australian policy was developed haphazardly and the outcome was far from inevitable. As scientific understanding of ozone depletion advanced during the 1980s, there was an increase in public concern and state politicians saw the opportunity to lead on a popular issue. The states took action early but inconsistently. Riding a wave of legitimate public concern, state ministers made many public pronouncements on the need for rapid action. At one point in the late 1980s, Tom Roper – then Victorian environment minister – bravely proclaimed that "Victoria leads the world". The Federal Government proceeded more cautiously, conscious of the need to be an effective part of the emerging international consensus. Throughout the 1980s, Australia was represented at international meetings by officials

from the Department of Foreign Affairs from whatever embassy or high commission near wherever the meeting was being held. The need to have officials that understood the scientific, industry and policy issues associated with ozone depletion was simply not acknowledged. Industry wanted a national response to ensure both consistency of approach and to provide longer term certainty regarding policy. It pushed the Federal Government to send Canberra-based experts, particularly from the Environment Department, to the international negotiations, given it was those officials who would need to lead a national response. Industry even had to provide the funding for the first such Commonwealth official to attend international meetings. This political dynamic changed during the 1990s for three main reasons. Firstly, there was a consumer backlash on the use of ozone depleting substances in aerosols. In response to this public pressure the then Aerosol Association brokered a ban on CFC use in aerosols.

volvement of the Federal Government. As part of this process, Paul Fraser of the CSIRO had been actively engaged with the Aerosol Association. That close engagement – followed by him working closely with the refrigeration and air conditioning industry – resulted in industry accepting both the science and the need for changing technology. This reduced time and acrimony in planning policy responses that, while economically and technically challenging, were clearly necessary. Lastly, there was significant confusion on the regulatory landscape. The states independently developed broad and diverse range of approaches, many of which were effectively unworkable. The Commonwealth Government eventually recognised the cost to industry from this dysfunction and decided to impose import level and some end use controls. Additionally, to better ensure national consistency, a committee was established that was led by the Commonwealth and included New Zealand and all of the states and territories, as well as a wide range of stakeholders. This body managed to corral many of the "seat of the pants" ideas which emerged and worked towards a nationally consistent approach. By the late 1990s, the states were losing interest in ozone Former Refrigerants policy, while the Australia executive director, Steve Anderson. C om m o n w e a lt h

Government concurrently increased its engagement internationally, based on a non-partisan, scientifically based policy. The review of the Ozone Protection Act in 2001 was a pivotal moment in the development of Australian policy. It showed that while the cost of policy to protect the ozone layer had cost $1 billion to date, the benefit was seven times larger. Further analysis demonstrated that significant further benefits would be achieved if the legislation was extended to HFCs used as replacements of ozone depleting substances – if the Commonwealth managed all of the legislation centrally and if it also managed end use controls. These reforms were delivered with revi-

sions to the Ozone Act in 2003. The increased political interest in climate change from about 2005 shifted the policy landscape again. There was an increasing focus on using emissions trading to manage climate change emissions by public servants who had no knowledge or interest in how both ozone depleting substances and HFCs had been successfully managed for well over a decade. They were focused on economy-wide responses and operated from the naïve belief that every economic sector

could be managed identically. They refused to even engage the industry in genuine dialogue. Despite industry publicly supporting an HFC phasedown from 2007, a carbon price was introduced in 2013, and then repealed in 2015. This illfated exercise was driven by ex-Treasury bureaucrats with no understanding of the industry, who tried to impose a one-size-fits-all approach, straight out of a first year economics textbook. This policy experiment failed dismally in managing refrigerant emissions and only resulted in confusion and turmoil. Any environmental benefits were far overshadowed by market confusion, turmoil and pain. Thirty years after the Montreal Protocol was agreed, and with the carbon price in the rear view mirror, refrigerant policy is in a good place. Sensible, thoughtful policy has been implemented to deliver a phasedown of high GWP refrigerants in a measured way that delivers certainty both for the environment and for business. Over the last 30 years, emissions of refrigerants have decreased from the carbon dioxide equivalent of more than 100 million tonnes, to less than 10 million tonnes. Over the next 20 years that will be reduced to just over one million tonnes – a total reduction of about 99 per cent. As the former Environment Minister said in 2015, no other sector in the Australian economy has delivered environmental benefits anywhere near this amount particularly while continuing to prosper and develop. While initially uncertain, 30 years after the Montreal Protocol, Australia is managing issues around refrigerants well and will continue to do so into the future. ✺

Time to set air leakage performance level REDUCING AIR LEAKAGE IS ONE OF THE MOST COSTEFFECTIVE WAYS TO IMPROVE HOME COMFORT AND THE ENERGY PERFORMANCE OF RESIDENTIAL BUILDINGS. THIS IS PARTICULARLY TRUE FOR AUSTRALIA WHERE BUILDINGS ARE EXTREMELY LEAKY COMPARED TO THE REST OF THE WORLD.

CURRENTLY THE BUILDINGS in Australia have wide variability, between 1.4 and 39 air changes per hour. This is perhaps in part a result of our relatively moderate climate, but also the fact that, unlike many of our international peers, the National Construction Code does not set a quantified minimum. In its report entitled The Bottom Line, the Australian Sustainable Built Environment Council (ASBEC) and ClimateWorks point out that reduced air leakage can be achieved at low cost through improved workmanship to prevent loss of conditioned indoor air and infiltration of unwanted outside air. The report wants immediate action taken as part of the current review of the National Construction Code. While the Code requires residential buildings to include construction features that mini-

mise air leakage – such as specific requirements for common air leakage points in a building to be sealed, including exhaust fans, windows and doors – the Code does not set a minimum overall air leakage performance level that needs to be achieved. Until recently there had been relatively little practical testing of the air tightness of Australian dwellings. However, standard 'blower door' testing from 2015 in capital cities around Australia found that newly constructed buildings (less than three years old) had an average air leakage rate of approximately 15 air changes per hour Figure 5: Comparison of different countries’ Building at 50 pascal pressure code infiltration requirements for residential buildings with (ACH@50Pa, a standard measured results measure for air tightness).

opportunities to cost-effectively improve energy performance by improving air tightness to around 6 ACH@50Pa. An air leakage rate of 6 ACH@50Pa as modelled is a reasonable level for the Code to target in the short term. The CSIRO study found that 18 per cent of the houses tested were already at less than 8 ACH@50Pa, and around one third were less than 10 ACH@50Pa, even in the absence of specific infiltration rate requirements. This level of air tightness is also comparable with international standards and is what some leading builders have stated they are achieving as standard practice. At this level of air tightness, indoor moisture and pollutant levels can be managed by effective ventilation fans in the kitchen and bathroom – heat recovery ventilation is not generally needed to ensure energy efficient fresh air delivery at this level. Other cost effective opportunities identified in the report include: • Increasing roof insulation for detached housing; • Using ceiling fans in warm and hot climates to reduce the need for air conditioning; • Increased requirements for wall insulation; • St ronger speci f icat ions for w i ndow performance; • Installation of roller shutters and larger eaves in certain orientations; and • Tighter standards for lighting and dometic hot water systems. ✺
