2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [1] [2] As a refrigerant, it is designated R-1234yf [1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [3]
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 ...
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]
Class 1: This class includes refrigerants that cool by phase change (typically boiling), using the refrigerant's latent heat. Class 2: These refrigerants cool by temperature change or 'sensible heat', the quantity of heat being the specific heat capacity x the temperature change. They are air, calcium chloride brine, sodium chloride brine ...
R-1234yf is a hydrofluoroolefin refrigerant that contains hydrogen, fluorine, and also carbon elements. The refrigerant was developed by the DuPont/Honeywell company and is more expensive per pound than R-134a. R-1234yf can be found in late-model cars and is not cross-compatible with older R-134a or R-12 systems.

1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12. Retrofit kits are available to convert units that were ...
