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
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 ...
Equipment to preserve and store goods, primarily foodstuffs, during transport by road, rail, air, and sea: R-134a, R-407C, R-410A: Electronic cooling: Low-temperature cooling of CMOS circuitry and other components in large computers and servers [10] R-134a, R-404A, R-507: Medical refrigeration R-134a, R-404A, R-507: Cryogenic refrigeration
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 ...
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 .
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.

From early 2020 HFCs (including R-404A, R-134a and R-410A) are being superseded: Residential air-conditioning systems and heat pumps are increasingly using R-32. This still has a GWP of more than 600. Progressive devices use refrigerants with almost no climate impact, namely R-290 (propane), R-600a (isobutane) or R-1234yf (less flammable, in cars).
