3 Green Cooling Association Inc Formed in early 2009 following the collapse of the Green Cooling Council Pty Ltd, an organisation established in 2003 to promote the interests of the natural refrigerants industry in Australia and with focus on improving energy efficiency as part of delivering climate friendly refrigerant solutionsComprised of around 60 individuals with an interest in NH3,CO2 and HCs, most of whom work in companies in the RAC industry in Australia, with a growing international membershipFocused on political and information barriers as much as promoting technical solutions, with an active interest in Montreal Protocol and international climate negotiationsSummarise GCC, $2m Govt grant to develop CO2 supermarkets,
4 The Ideological Divide - containment vs replacement? Fluorocarbon proponents in Australia working very hard to narrow the debate on refrigerant choice to arguments about measures to improve containment of fluorocarbonsCurrent licensing, accreditation and awareness efforts are represented as being a sufficient responseSignificant effort is expended on obtaining ‘independent expert’ advice to downplay the potential of natural refrigerants to replace fluorocarbonsFortunately, Government is not listening…
6 Carbon Pollution Reduction Scheme (CPRS) – Oz ETS outline Wide coverage – HFCs included, assumes they will leak, can generate emissions credits if gas is recovered and destroyedTiming – was to be July 2010, now delayed until 2011, assuming legislation passes SenateBroad coverage HFCs included, complementary legislative and regulatory changes to cover HCFCsMajor changes to refrigerant recovery and destruction being developed
7 CPRS outline - continued Statistics Norway study by Katherine Loe Hansen of key importance in influencing Government positionScheme will put a high cost on imports of high GWP refrigerant using an ‘upstream’ approach – large entities will have to acquire emissions permits, smaller importers will be included through higher import levies to achieve same price as paid by large importersFluorolobby fighting tooth and nail to win exemption from coverage, very unlikely Govt will concede to their demandsAlready having a large impact on selection of new systems, this is expected to become much greater when scheme takes effect
8 Importance of defending the claim to be “environmentally friendly” Vital for naturals to defend competitive advantagesHighly deceptive claims becoming increasingly frequent around the worldEffective regulatory action taken in Australia in 2003

11 About the case studiesMuch of the refrigeration and air conditioning equipment in Australia uses fluorocarbon refrigerants to facilitate the heat transfer process. Fluorocarbon refrigerants are synthetic chemicals which usually have a high global warming potential, and some still have the potential to cause damage to the ozone layer as well if released to the atmosphere.Alternatives to these chemicals exist that can help to mitigate some of the environmental risks. Often referred to as 'natural' refrigerants because the substances also occur in nature, these alternatives include ammonia, carbon dioxide and hydrocarbons.These substances have been used as refrigerants for many years, however, they are now finding their way into applications where previously fluorocarbons were the preferred option.This document has been put together to provide industry decision makers with more information on the potential of 'natural' refrigerants. It includes an overview of each of the alternatives, case studies on how they've been put to use in Australia, and pointers to some sources of further information.The case studies are written in plain English, and attempt to give a realistic picture of how alternatives to fluorocarbon refrigerants were used in each case – the advantages they provided, the challenges that needed to be overcome, and the drivers behind each project.
12 Domestic Refrigeration Imported brands including Vestfrost, Miele, Liebherr and Bosch are long established, but occupy niche positions in high-end and off-grid marketsElectrolux – own the only domestic fridge manufacturing facility remaining in Australia, and have converted their own brand to Hychill Minus30 (R600a)Electrolux plans to introduce HC to their many other brands in near futureFisher and Paykel – have yet to announce a HC range
13 Industrial Refrigeration Natural refrigerants have an established history and are now in common useFirst CO2 system built in Bundaberg, Qld in 2002, started to gain acceptance between 5-8 years ago, but in last 3-4 years has become the accepted best choiceSingle stage and 2 stage NH3Cascade CO2/NH3 – low temp and medium temp applicationsNH3 (small charge in plant room) and secondary (glycol) systemsOrganic brines – CO2 – Low TempSpiral, Inline, Blast and Plate Freezers using CO2 and NH3Companies delivering custom built systems include Grasso, Scantec, RefEng RealCold, TriTech, Gordon Bros, Johnson Controls, eCO2 TechnologiesExamples –Major supermarket chains operating 8 large distribution centres using NH3 glycol systems, fruit storage, and food processing facilitiesOrder has just been placed for Australia’s first transcritical CO2 large food processing facility, in QLD, for a desert and chocolate producer

16 Small Commercial Refrigeration Unilever has distributed 100,000 hydrocarbon ice cream chest freezers since 2007Other players in the Fast Moving Consumer Goods sector have not yet embraced the shift to CO2 or HCs, and have objected to the Emissions Trading SchemeSome manufacturers perceive industry resistance to hydrocarbons, and have yet to develop HC cabinetsThere is experience with HCs in on farm milk vats, but in spite of excellent results, use has been limited
17 Large Commercial Refrigeration Bitzer - dominant compressor supplierEstimate there are over 60 supermarkets using CO2 in Australia & NZNew ZealandAt least 3 systems in the North IslandFoodstuffs in the South Island built first in Nov 2006, and has recently opened their sixth at Lincoln on the outskirts of ChristchurchAnother being opened in Timaru in 2 months time, and a further 2 are planned for the first half of next yearAustraliaVery strong growth is being experiencedThere are an estimated 50 stores in operationOrders for new systems are coming in fastWoolworths are pursuing CO2 systems aggressivelyColes direction have recently undergone a major reorganisation, but appear to remain committed to pursuing CO2
18 Large Commercial Refrigeration Debate within the industry continues on the optimal system designs for the wide range of Australian/NZ conditions, and there is a steep learning curve, technical discussions at GL2010 should prove highly instructive.Higher up front capital costs are well understood, but energy and refrigerant savings are such that even in the absence of the Australian ETS, payback periods are sufficiently short for the decision to adopt CO2 to be a ‘no brainer’.ECO2 technologies – offering Enex transcritical systems designed for use in hot climates, have faced reluctance but expect to have orders placed soon. Australian contractors Frigrite helped install first CO2 cascade system in Thailand at Tesco Salaya in 2007

25 Mobile Air Conditioning Hydrocarbon Refrigerants in Motor Vehicle AC Systems– The Australian StoryFirst batch of Australian made R12/R134a replacement of 50kg produced by LPG Management Technology for Esanty Refrigerants in 1990.Since that date over 200 tonnes of HC has been sold in Australia to the MAC re-gas market.HyChill is one of 3 suppliers to the market in Australia, along with Technochem and ERG – so the total is larger than this number.As 200 tonnes of HC replaces 600 tonnes of R134a, this has avoided over 800,000,000 Kg of CO2 emissions.Current estimate of annual sales is around tonnes.
26 Australian use of HCs in MVACS (cont.) At least one small scale vehicle manufacturer uses HyChill refrigerants in their production. Another manufacturer is seriously considering the issue because of the excellent results being achieved by one of their distributors who converts the systems to HC prior to delivery.A number of Original Equipment Manufacturer distributors are removing R134a and replacing it with HC prior to delivery of new vehicles.A number of mining operators have a policy that HFC’s and HCFC’s are prohibited from their site in all vehicles and all MUST be changed to HC before being brought into service. Why?Because of the environmental impact of the gas and the oilImproved performance in extreme conditions (there are many examples of R134a approaching critical temperature leading to equipment failure in high ambient temperature environments - a significant cost issue!)because their (mandatory) risk assessments show there is no significant additional safety risk, they are of the view that HC and mineral oil are a lower overall risk than HFC and PAG oil.Mining companies have the expertise in house to do their own risk assessments !
27 Australian use of HCs in MVACS – the evidence of this sidelined solution? An October 2008 report* prepared for the Australian Department of Environment, Water, Heritage and the Arts revealed that 5.5% of refrigerant recovered from the MVAC sector was HC. Given that the shops that use HC’s regularly know that there is no need to recover HC’s, it seems clear that the actual percentage of vehicles on the road using HC’s is somewhat higher than this.Collated industry data indicates that approximately 10% to 15% of vehicles on the road use HC’s.Sales are greatest in rural servicing centres, reflecting use in agricultural equipment.Many TAFE (Technical and Further Education) colleges in Australia now teach the safe uses of HC’s in MAC’s as part of their normal training for tradesmen/apprentices.Clearly, there is a pressing need for a further independent assessment of the extent of use of HCs in Australia, and around the world, to demonstrate that HCs are a viable option for more widespread use.*Energy Strategies, “ODS and SGGs in Australia - A study of end uses, emissions and opportunities for reclamation”, October 2008,for the Australian Department of Environment, Water, Heritage and the Arts (DEWHA)Invite suitably qualified academic researchers interested in an Australian study tour to catch up at dinner!
28 Australian use of HCs in MVACS – Safety concerns? The only documented incidents in Australia are simply the result of failure to comply with normal workshop safety practices.The highlighting of these incidents by the fluorolobby shows how disingenuous their concerns about safety really are, as there are also documented reports of workshop incidents with MVAC’s using HFC’s where normal workshop safety practices were not followed.The paper titled “Usage and risk of hydrocarbon refrigerants in motor cars for Australia and the United States” published in the International Journal of Refrigeration 27(2004) 339–345 is a peer reviewed document that shows the risk associated with the use of HC’s in MVAC’s has been overstated by those who have previously done risk assessments.Those who continue to call for further analysis and studies studiously ignore this paper and all the other real world evidence when they continue to call for further risk assessments. Organizations such as the USEPA are simply acting as the “pawns” of the FC lobby in continuing their objections to HC’s in MVAC’s.The majority of risk assessments that this paper thoroughly refutes were commissioned by fluorolobby vested interests for the explicit purpose of conducting negative marketing campaigns, and to influence OEM’s and regulators, and not as objective attempts to assess the suitability of HC’s as refrigerants in MVAC’s.
30 Regional Highlights Experience with HCs in SE Asia Increasingly significant level of retrofitting of existing systems with hydrocarbon is taking place in many countries, including Thailand, Malaysia & SingaporeCompanies supplying include Chatcooling, RedTek Thailand, Coolman Group, Nat Energy Singapore, Hychill Fueltreat Malaysia, Pertamina and Energy Resources GroupWide range of systems involved, impressive energy efficiency gains being delivered and driving wider use
31 APL Asia Co., Ltd. is promoting the use of Environmentally Friendly, Energy Efficient REDTEK Hydrocarbon Refrigerant from USA in an attempt to reduce the use of CFC, HFC and HCFC refrigerant gases, which are causing irreparable damage to the environment.Our company is based in Thailand and distributes REDTEK refrigerant throughout Asia, to companies with a similar philosophy to ours. Our main activities are based in Thailand and involve the replacement of mainly R22 with REDTEK 22a hydrocarbon refrigerant, to companies who want to 1) use environmentally friendly products to reduce damage to our environment and 2) reduce running costs by reducing the use of electricity, which results in a reduction in the quantity of electricity that needs generating and therefore again helps reduce gas emissions into the environment.As HC gas is combustible, under certain conditions, we survey our customer facilities to ensure we will not causing an unsafe condition. We follow the ACRIB guidelines mainly for volume of refrigerant in a particular area, if refrigerant was released from an A/C system. We will not install if we have any doubts concerning safety.
32 All A/C systems converted are labeled to indicate the presence of hydrocarbon refrigerant. We also provide training to our customer’s staff on the safe use and charging procedure for hydrocarbon refrigerant. The MSDS is supplied to every customer, approval is usually obtained from their head office and we do not have many problems in convincing customers to change to an environmentally acceptable alternative, especially when they witness the significant energy saving they can obtain.The advantage with Hydrocarbon Refrigerant is that it is not a “retrofit” product, it is a drop in replacement with no modification or replacement of components, lubricating oil etc. required.All refrigerant removed from air conditioning systems is recovered, cleaned, dried and reused as there is not a refrigerant destruction facility in Thailand. Our intention is to reduce the quantity of new refrigerant manufactured.Our customers, for refrigerant replacement, are mainly factories where they have dedicated staff for maintenance of air conditioning systems and we can be confident on safety issues.Following are some examples of HC replacement projects showing the saving in power we achieve, these results are for split type, chillers (reciprocating and screw compressors), package units, at the moment we are converting several factories each month and we see our workload increasing as the world says goodbye to harmful chemical refrigerants :
34 NAT ENERGY RESOURCES PRIVATE LIMITED NAT ENERGY RESOURCES PRIVATE LIMITED was incorporated in Singapore in February Our Company was set up primarily to propagate the application of Hydrocarbon Technology onto all buildings and automobiles with air-conditioning systems.Our aim is to reduce energy costs for all our customers and at the same time improve the environment by reducing carbon dioxide emissions. As an ecofriendly Company, we are duty-bound to replace the high GWP (Global Warming Potential) causing HFC refrigerants with the almost zero GWP hydrocarbon refrigerant.

38 Where will we be in another 15 years..? "The present situation, when CFCs and in a little longer perspective the HCFCs are being banned by international agreement, it does not seem very logical to try to replace them by another family of related halocarbons, the HFCs, equally foreign to nature. In any case it must obviously be much preferable to use natural compounds, which are already circulating in quantity in the biosphere and are known to be harmless." * -Professor Gustav Lorentzen (Norway, 1994)2009Greenpeace Cartoon – 1994
