HVACR refrigerants that have been delisted include: Retrofitted supermarket systems: R-404A, R-407B, R-421B, R-422A, R- 422C, R-422D, R-428A, R-434A, and R-507A as of July 20, 2016 New supermarket systems: HFC- 227ea, R-404A, R-407B, R-421B, R- 422A, R-422C, R-422D, R-428A, R- 434A, and R-507A as of January 1, 2017 The production of chlorofluorocarbons, commonly known as CFCs, was banned in the 1990s. It has potential for certain applications and is being used in blends but has previously been rejected as a single component refrigerant due to its A2 flammability. MVAC refrigerants are listed as either acceptable subject to use conditions or unacceptable. Again, the answer depends on the age of the air conditioner itself. HFC-134a is the primary refrigerant currently used to retrofit CFC-12 systems. Puron also benefits from being considerably cheaper than freon. To reiterate an earlier point, replacing your AC is a good idea if. The refrigerant starts by leaving the receiver, which acts as a storage container for the refrigerant. The cost of R410A is just a fraction of the cost of R22. This would be another reason why many experts suggest that those who still own freon-based HVAC units have them replaced. On the EPA website, there is a long list of refrigerants allowed for stand-alone equipment. What you should do Check your equipment and see if it is one of these two types of refrigeration system.

Unless you are licensed to handle R410A, you are not legally allowed to refill any system with it. H\n@Q> TdNJE9|wnvihqvox&St}.\5\16?YUG:y{)>fS_qm6t/F/m:?ctrL36MjbwV\v:7) Ozone is "good up high, bad nearby." It is also not going to be cheap. %PDF-1.4 % After 2020, the servicing of systems with R-22 will rely on recycled or stockpiled quantities . In some cases, there will also be a small sticker on the air conditioner that will tell you what type of coolant it uses too. 0000047669 00000 n This means that leaking R410A is hugely dangerous to the environment. This is because it is far better at being able to pull the heat out of the air. R-22 refrigerant was made in the late 1990's to temporarily replace R-12 due to its lower ODP. While there are plans to phase it out soon, many modern air conditioners are being built to use R410A as part of their cooling system. So, what is that all about? endstream endobj 318 0 obj <>stream You have a couple of methods available to you. The HFO refrigerant R1234yf, designed as a replacement for R134a in car air conditioning systems, is extended for use in newly manufactured medium-duty passenger vehicles, heavy-duty pickup trucks, and complete HD vans. If you wish to convert your R22 system to an R410A, this will need to be carried out by a specialist. New stand-alone medium-temperature units with a compressor capacity equal to or greater than 2,200 Btu/hr and stand-alone medium-temperature units containing a flooded evaporator: FOR12A, FOR12B, HFC134a, HFC227ea, KDD6, R125/290/134a/600a (55.0/1.0/42.5/1.5), R404A, R407A, R407B, R407C, R407F, R410A, R-410B, R417A, R421A, R 421B, R422A, R422B, R422C, R 422D, R424A, R426A, R428A, R434A, R437A, R438A, R507A, RS24 (2002 formulation), RS44 (2003 formulation), SP34E, and THR03 as of January 1, 2020. Even though it protects us when it is in the stratosphere, ozone at ground level can be harmful to breathe and is a prime ingredient in smog. The sales restriction covers refrigerants contained in cylinders, cans, or drums, except for the sale of small cans of substitute refrigerants (e.g., R-134a for use in motor vehicle air conditioners). When considering alternative refrigerants, As of 2020, production in developed countries is banned, and developing countries will see a ban from 2030. At that point, you will probably be best off buying a new air conditioner.
