  2. 2,3,3,3-Tetrafluoropropene - Wikipedia

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

    R-1234yf is also a component of zeotropic refrigerant blend R-454B. HFO-1234yf has a GWP less than carbon dioxide, [4] [2] itself 1,430 times less potent than R-134a. [5] For this reason, 2,3,3,3‑tetrafluoropropene is the pre-eminent replacement for R-134a in vehicular air conditioners. As of 2022, 90% of new U.S. vehicles are estimated to ...

    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 ...

  6. Compatibility (chemical) - Wikipedia

    en.wikipedia.org/wiki/Compatibility_(chemical)

    Chemical compatibility is a rough measure of how stable a substance is when mixed with another substance. [1] If two substances can mix together and not undergo a chemical reaction, they are considered compatible. Incompatible chemicals react with each other, and can cause corrosion, mechanical weakening, evolution of gas, fire, or other ...

  7. 1,1,2,2-Tetrafluoroethane - Wikipedia

    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.
