For this reason, 2,3,3,3‑tetrafluoropropene is the pre-eminent replacement for R-134a in vehicular air conditioners. As of 2022, 90% of new U.S. vehicles are estimated to use HFO-1234yf. [6] Unlike previous vehicular refrigerants, 2,3,3,3‑tetrafluoropropene is flammable, but does not increase fire risk in internal combustion engines.
R-410A is a refrigerant used in air conditioning and heat pump applications. It is a zeotropic but near-azeotropic mixture of difluoromethane (CH 2 F 2, called R-32) and pentafluoroethane (CHF 2 CF 3, called R-125). R-410A is sold under the trademarked names AZ-20, EcoFluor R410, Forane 410A, Genetron R410A, Puron, and Suva 410A.
This refrigerant was designed as a drop-in replacement for dichlorodifluoromethane (R-12) which is compatible with the typical mineral oil lubricants used in R-12 systems. Since it is a zeotropic mixture , it has a range of boiling points which may increase the effectiveness of the heat transfer elements in refrigeration equipment.
Drop-in replacement is a term used in computer science and other fields. It refers to the ability to replace one hardware or software component with another, without any other code or configuration changes being required and resulting in no negative impacts. Usually, the replacement has some benefits including one or more of the following:
