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 ...
Critical temperature in degrees Celsius Absolute critical pressure in kilopascals Since over 100,000 refrigerant blends are possible, [ 2 ] this list should only have notable refrigerants and refrigerant blends.
Solubility of water in HFC-134a at 25 °C 0.11% by weight Flammability Limits in Air at 1 atm None Autoignition temperature 770 °C (1,420 °F) Ozone depletion potential: 0 Halocarbon Global Warming Potential (HGWP) (For CFC-11, HGWP = 1) 0.28 Global Warming Potential (GWP) (100 yr ITH. For CO 2, GWP = 1) 1,200
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. [68] It has an atmospheric lifetime of nearly 5 years. [69] Currently used in residential and commercial air-conditioners and heat pumps. R-134a HFC ...
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].
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 ...
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.
Most are gases at room temperature and pressure. 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 .
