This is a list of refrigerants, sorted by their ASHRAE-designated numbers, commonly known as R numbers. Many modern refrigerants are human-made halogenated gases, ...
A refrigerant is a working fluid used in the cooling, heating, or reverse cooling/heating cycles of air conditioning systems and heat pumps, where 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] as well as the contribution of CFC ...
R-410A was invented and patented by Allied Signal (later Honeywell) in 1991. [5] Other producers around the world have been licensed to manufacture and sell R-410A. [6] R-410A was successfully commercialized in the air conditioning segment by a combined effort of Carrier Corporation, Emerson Climate Technologies, Inc., Copeland Scroll Compressors (a division of Emerson Electric Company), and ...

'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type. They emit a strong smell similar to acetone . [ 2 ]
Shipping container for the gas, shown in Japan. Pentafluoroethane in a near azeotropic mixture with difluoromethane is known as R-410A, a common replacement for various chlorofluorocarbons (commonly known as Freon) in new refrigerant systems.
HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a [1] and Hydrocarbon Blend B, is marketed as a "drop-in" replacement refrigerant for R-12 and other refrigerants. HC-12a is a mixture of hydrocarbons, specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting. The hydrocarbon blend is compatible ...
1,1,1-Trifluoroethane, or R-143a or simply trifluoroethane, is a hydrofluorocarbon (HFC) compound that is a colorless gas. It should not be confused with the much more commonly used HFC gas R-134a, nor confused with the isomeric compound 1,1,2-trifluoroethane. 1,1,1-Trifluoroethane has a critical temperature of 73 °C.
