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 ...
In the late 1920s, a research team was formed by Charles Franklin Kettering in General Motors to find a replacement for the dangerous refrigerants then in use, such as ammonia. [3] The team was headed by Thomas Midgley Jr. [ 4 ] In 1928, they improved the synthesis of CFCs and demonstrated their usefulness for such a purpose and their stability ...
trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin.It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters. [3]
CARE 30 is a refrigerant consisting of a blend of isobutane (R-600a) and propane (R-290) developed to replace dichlorodifluoromethane (R-12) and 1,1,1,2-tetrafluoroethane (R-134a). [1] It is primarily for use in small commercial refrigeration and air-conditioning systems that have traditionally used R-12.
