R-410A. 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.

Reclaiming R-410A can reduce lifecycle greenhouse gas emissions by up to 70% compared to producing virgin refrigerant. Maximizing refrigerant reclamation to serve ACHP equipment in U.S. homes can avoid 7.7 metric tons of CO2 emissions by 2045–equivalent to taking 1.8 million cars off the road for a year.
Refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability [ 1 ] and the contribution of CFC and HCFC ...
Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. In compliance with the Montreal Protocol, its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries ...
