    en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene

    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]

    HFOs in use include: 2,3,3,3-tetrafluoropropene (HFO-1234yf, trademarked as Opteon YF) and 1,3,3,3-tetrafluoropropene (HFO-1234ze). [7]cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz-Z; DR-2) shows also a promise in high temperature applications like cogeneration, heat recovery and medium temperature heat pumps.

    en.wikipedia.org/wiki/Polyolester

    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 ...

    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. Of the three refrigerants, R-1234yf is the best for the environment with the lowest global warming potential number which is about a three.
