R-410A is a near-azeotropic mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane (C2HF5, called R-125), which is used as a refrigerant in air conditioning applications. Unlike many haloalkane refrigerants it does not contribute to ozone depletion, and is therefore widely used. Carrier Corporation was the first company to introduce a R-410A-based residential air conditioning unit in the marketplace in 1996. Now R-410A is the preferred refrigerant for use in residential and commercial air conditioners in Japan and Europe, replacing R-22.
