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 ...

   Because of its reduced global warming potential (GWP), R-454B is intended to be an alternative to refrigerant R-410A in new equipment. [2] [3] [4] R-454B has a GWP of 466, which is 78 percent lower than R-410A's GWP of 2088. [2] R-454B is non-toxic and mildly flammable, with an ASHRAE safety classification of A2L. In the United States, it is ...

   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] The use of R-134a is being phased out because of its high global warming ...

9. Automotive air conditioning - Wikipedia

   en.wikipedia.org/wiki/Automotive_air_conditioning

   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.
