Wholesalers that sell refrigerant for resale are legally responsible for ensuring that their customers fit into one of the categories of allowed purchasers under the sales restriction. Thus, CFC-12 may also be written as R-12 or Refrigerant 12.An alkene, olefin, or olefine is an unsaturated compound containing at least one carbon-carbon double bond.[73]. R134a is one of a number of common refrigerants that will be banned from use in new centrifugal and positive displacement chillers as of January 1, 2024. UNEP, 2000. This is because an R134A systm converts between gas and liquid at a vastly different temperature than R22. 0000047669 00000 n It is also not going to be cheap. You may also notice that it can be exceedingly difficult to find an R22 replacement. The illegal refrigerant trade makes use of non-recyclable canisters, making them instantly recognisable by buyers. This way, you can be sure that you are using a better product (but still not great) for the environment. Since R410A is still being manufactured, it is a lot more affordable to recharge your R410A system. Stand-alone units are . Do you need to toss this one, replacing it with a more environmentally-friendly option? 0000008350 00000 n At the most, it is going to cause you a little bit of pain. 0000009546 00000 n 0000009843 00000 n Since 1994, the most common refrigerant used in MVAC systems has been hydrofluorocarbon (HFC)-134a. The regulations on refrigerant phaseouts in Canada and the USA are similar. The refrigerant, which contains chlorine, has a huge environmental impact.

Ban on remaining production and import of HCFC-22 and HCFC-142b. You can no longer find a new air conditioner or heat pump that uses R-22. You probably wouldnt break the components inside the air conditioner either. `)ZYs#="bmJ{gG 8; An R22 system probably wouldnt work if you placed R410A into it. 0000137524 00000 n The reason for this change is to help protect the environment. While R-32 is still going to impact the environment, it is said that it only impacts the environment about a third as much as R410A, which certainl does make it a suitable replacement. If you do this, then it should be perfectly fine to load up with R410A. In China, CFC emissions have had a, When the environmental impact of CFCs was not deemed acceptable, the industry, including Koura Klea refrigerants. Even now, it is tough to find in some areas. Barring that, ask your HVAC technician the next time you have the unit checked out. Employers of a Section 608 certified technician (or the employer's authorized representative) if the employer provides the refrigerant wholesaler with written evidence that he or she employs at least one properly certified technician. 0000122947 00000 n It only operates at 400psi. R-32 is the refrigerant that is likely to end up replacing R410A over the next few decades. The R number of a chemical refrigerant is assigned systematically according to molecular structure. endstream endobj 310 0 obj <>stream The table is sortable by each of the following refrigerant properties (scroll right or reduce magnification to view more properties): Since over 100,000 refrigerant blends are possible,[1] this list should only have notable refrigerants and refrigerant blends.

Read common questions and answers on the refrigerant sales restriction and the online sale of refrigerants, Questions and answers on the refrigerant sales restriction and the online sale of refrigerants, Major recordkeeping requirements for refrigerant wholesalers, Fact Sheet: How the revised 608 Rule affects refrigerant distributors. endstream endobj 318 0 obj <>stream Chlorofluorocarbons ( CFCs) and hydrochlorofluorocarbons ( HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane. The same two refrigerants and 19 others are being listed as unacceptable in new cold storage warehouses from January 1, 2023. Without it, the air conditioner wouldnt be able to cool down anything. In addition, flammable propylene and the hydrocarbon blend R443A are listed as unacceptable for use in new residential and light commercial AC and heat pumps, cold storage warehouses, centrifugal chillers, and positive displacement chillers. The following people can generally buy any type of ozone-depleting or substitute refrigerant under this sales restriction: The following people can buy refrigerant found acceptable for use in a motor vehicle air conditioner (MVAC): Only Section 608 certified technicians can purchase refrigerants intended for use with stationary refrigeration and air-conditioning equipment. The new delisted refrigerant list includes those used in new and retrofit equipment applications for food refrigeration equipment and vending machines, as well as new remote condensing equipment. MVAC systems are one end-use within the refrigeration and air conditioning sector. Myhre, G., D. Shindell, F.M. The most commonly used refrigerant that will be subject to these bans is the F-gas HFC-134a, with a GWP of 1,430. When a refrigerant is listed as unacceptable, its use is illegal. This would be another reason why many experts suggest that those who still own freon-based HVAC units have them replaced. Canisters must be recyclable. %%EOF If you do not have a sticker on the air conditioner, you will need to consult the manual for your air conditioner. The acceptable alternatives list is evaluated by the EPA and revised as necessary as alternatives become available for specific applications. 0000068902 00000 n HFC-134a is the primary refrigerant currently used to retrofit CFC-12 systems. {@}shUL>/JnVZg+cmAa)}s"b4X1jDRq*?K.oEw)4Zj. .<6'b47 C"3-LqpN;ynDmn0QwW&L[3nYdi^/}jiz-Y0dZ_ XIk THE NEFAB GROUP'S LIST OF BANNED & RESTRICTED SUBSTANCES 10.1.

Expect that to change from about 2024 onward when R410A begins the period where it is phased out. The most common alternative in new AC systems is R-410A, which is known by trade names such as GENETRON AZ-20 , SUVA 410A , Forane 410A, and Puron . This will help to prevent HFCs from seeping into the atmosphere. R-22 has been proven repeatedly to be a significant cause of damage to the ozone layer. An official website of the United States government. There, you are not even allowed to repair systems using R22 now. Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. If you purchase an air conditioner nowadays, it is likely to use a refrigerant known as R410A. This is better than previous refrigerant options (CFC and HCFC). . Plattner, M. Tignor, S.K. None of these deplete the ozone layer and all have significantly lower impacts on the climate system than HFC134a. H[O@W#J ,\NP"G{93Y The development of MVAC systems using lower-GWP refrigerants has been encouraged by MVAC refrigerant requirements in Europe, where the EU Directive on Mobile Air Conditioning (MAC Directive) mandates transition to a refrigerant with a GWP below 150 by January 1, 2017, and in the United States by the availability of credits under the MY 2017-2025Light-Duty Greenhouse (LD GHG) Rule (77 FR 62624, October 15, 2012). The hope is that having experts refill the air conditioner means that any leaks are spotted and patched up. If you add R134A into the system, it wont be efficient at all. The air wouldnt cool down. Now, lets discuss what you need to do going forward if your unit is old enough to rely on freon to work correctly. This has only been applied since January 2018. Still need help? It hasnt been actively produced for several years now. If so, you will want to keep in mind that this work can be quite costly.

Industrial process air-conditioning units, which are distinct from commercial and residential air conditioning, provide comfort cooling for operators and protect process equipment. 0000001913 00000 n Is R22 still available? Although the regulation does not specify precautions that wholesalers must take to verify the intent of individuals purchasing refrigerant, EPA recommends that wholesalers obtain a signed statement from the purchaser indicatingthat he or she is purchasing the refrigerant only for eventual resale to certified technicians. If you still dont know, then talk to an air conditioner service agent. Ruud vs. Goodman: Which Air Conditioner is Better? This means that if you find any R22, it will either have been produced before the phase-out or recovered from old, decommissioned air conditioners. 0000002241 00000 n This means that leaking R410A is hugely dangerous to the environment. cq2S#xLT7z_0rVrgVowCQQQ0vuLJWim@jmJ0UX0"5P$,% |Ii{Rn2ADf4,QpO5 "U4*g;kag%_$''v?%u07pr(';(?7BN'nz } r~nb. This exception will be allowed until the year of 2024. 0 HFO-1234yf MVAC systems must adhere to all of the safety requirements of SAE J639 (adopted 2011), including requirements for a flammable refrigerant warning label, high-pressure compressor cutoff switch and pressure relief devices, and unique fittings. This has triggered some speculation about the incentives for A5 counties to have an early move to low-GWP refrigerants as this would decrease their baseline. Carrier, Johnson Controls and the Air Conditioning, Heating, and Refrigeration Institute (AHRI) had all argued for a date no earlier than 2025. HFC-134a will no longer be approved for use in new light-duty vehicles manufactured or sold in the United States as of model year 2021 as a result of EPAs. At the moment, the EU Commission, EFCTC and refrigerant industry are raising awareness and exercising authority where possible to encourage a joint approach to stamping out banned refrigerants. After 2020, the servicing of systems with R-22 will rely on recycled or stockpiled quantities . EPA recommends, but does not require, that wholesalers keep lists of authorized representatives to help with this determination. C=1 i.e. When a refrigerant is listed as unacceptable, its use is illegal. When the environmental impact of CFCs was not deemed acceptable, the industry, including Koura Klea refrigerants, began to innovate. Many modern refrigerants are man-made halogenatedgases, especially fluorinated gasesand chlorinated gases, that are frequently referred to as Freon(a registered trademark of Chemours). HOC = Heat Of Combustion, Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes "R-" or "Refrigerant." 0000006728 00000 n Therefore, nothing would happen. The ban is obligatory on both windows as well as split ACs containing refrigerants. LFL = Lower Flammability Limit HCFC 22 -48% CFC 115 -52% : R503 CFC: No; banned under Montreal protocol: Low temperature refrigerant -80 to -100C. R410A will likely start to be phased out in 2024.
