2. R-410A - Wikipedia

   en.wikipedia.org/wiki/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.

6. Pentafluoroethane - Wikipedia

   en.wikipedia.org/wiki/Pentafluoroethane

   Pentafluoroethane is a fluorocarbon with the formula CF 3 CHF 2. Pentafluoroethane is currently used as a refrigerant (known as R-125) and also used as a fire suppression agent in fire suppression systems. Pentafluoroethane does not deplete ozone so it has replaced earlier fluorinated chemicals that did.
