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.

They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC refrigerants. In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol ...
Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12, as these systems traditionally use mineral oil, [2] which HFC-134a does not mix ...
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.
In open atmosphere however, HFO-1234ze actually forms HFC-23 as one of its secondary atmospheric breakdown products. HFC-23 is a very potent greenhouse gas with a GWP100 of 14,800. This makes the secondary GWP of R-1234ze in the range of 1,400±700 considering the amount of HFC-23 which may form from HFO-1234ze in the atmosphere.
