If this option works for you, then, by all means, utilize it as a means of adapting to the new EPA regulations for freon and air conditioners. A "B" number means that one of the chlorine atoms is replaced by bromine (Br). Not only has it been shown to be more efficient, but it has also been shown to be much more environmentally sound when compared to freon. The liquefied refrigerant (D) is ready for a new cycle. At the very least, they can determine whether or not your AC unit can be retrofitted in this fashion, to begin with. 0000001913 00000 n The most common alternative refrigerant to R-22 is R-410A, which is sold under various names, such as GENTRON AZ-20 , SUVA 410A, and PURON . The U.S. Environmental Protection Agency (EPA) recently released a new list of refrigerants to be delisted. You do not need any certification to buy an R410A refrigerant. . endstream endobj 324 0 obj <>stream Therefore, nothing would happen. Well, that is if it even works. Ban on remaining production and import of all HCFCs . 2. An official website of the United States government. However, you can expect it to cost about $5,000 to upgrade an air conditioner to use R410A refrigerant. For this reason, the material has been gradually eliminated from the production process involved in creating new HVAC units. If you purchase an air conditioner nowadays, it is likely to use a refrigerant known as R410A. This includes all hydrocarbon refrigerants. If you tried to put R32 into a system designed for R410A, then the air conditioner will not work. + This means it is getting close to the end of its lifespan. Acceptable, subject to use conditions, for new passenger cars and light-duty trucks only (March 29, 2011, 76 FR 17488; March 26, 2012, 77 FR 17344), Mildly flammable (ASHRAE A2L), but can be used safely, Models using HFO-1234yf include: Cadillac XTS, Chevrolet Spark EV, BMW i3 and i8, Chrysler 200, Chrysler 300, Dodge Challenger, Dodge Charger, Dodge Dart, Dodge Durango, Jeep Cherokee, Jeep Wrangler, Ram 1500, Fiat 500 and 500L, Alfa Romeo 4C, Honda Fit EV, Tesla Model S, Range Rover, and Range Rover Sport. 0000009113 00000 n Need to anonymously report illegal refrigerants?
