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 ...
Normal boiling points for pure substances, bubble and dew points for zeotropic blends, or normal boiling point and azeotropic temperature for the azeotropic blends, at 101,325 Pa (1 atmosphere) and in degrees Celsius; Critical temperature in degrees Celsius; Absolute critical pressure in kilopascals
R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1,1,1,2-tetrafluoroethane (R-134a), which has an insignificant ozone depletion potential. Automobile manufacturers began phasing in R-134a around 1993 [citation needed].
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 ...
Dichlorodifluoromethane (R-12 or CFC-12), the most commonly used Freon brand refrigerant prior to its ban in many countries in 1996 and total ban in 2010. 1,1,1,2-Tetrafluoroethane (R-134a or HFC-134a), one of the main replacements for the formerly widespread R-12. Opteon halogenated olefins now replacing Freons in many applications.
Dichlorodifluoromethane (R-12) CF 2 Cl 2: 2.9: 120.91: 6 1: 8100 strong Vapor pressure 90 psi (6.1 atm) at 23 °C, yielding breakdown voltage 17 times higher than air at 1 atm. Higher breakdown voltages can be achieved by increasing pressure by adding nitrogen. Corrosive decomposition products. Trifluoromethane: CF 3 H: 0.8: weak 1,1,1,3,3,3 ...

The second automotive air conditioning refrigerant invented was R-134a. R-134a is a hydrofluorocarbon refrigerant that contains fluorine and hydrogen. The successor to R-12, R-134a was a new refrigerant that no longer contained chlorine that could deplete the ozone layer. R-134a is a greenhouse gas, it has a lower global warming potential than ...
