1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...

1,1,2,2-Tetrafluoroethane (also called R-134 or HFC-134) is a hydrofluorocarbon, a fluorinated alkane. It is an isomer of the more-used 1,1,1,2-tetrafluoroethane (R-134a). It is used as a foam expansion agent and heat transfer fluid.

For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...

Promoted as climate-friendly substitute for R-134a and R-410A, but still with high climate impact. Has excellent heat transfer and pressure drop performance, both in condensation and vaporisation. [66] It has an atmospheric lifetime of nearly 5 years. [67] Currently used in residential and commercial air-conditioners and heat pumps. R-134a HFC ...
HFCs replaced older chlorofluorocarbons such as R-12 and hydrochlorofluorocarbons such as R-21. [2] HFCs are also used in insulating foams, aerosol propellants, as solvents and for fire protection. They may not harm the ozone layer as much as the compounds they replace, but they still contribute to global warming --- with some like ...
