2. trans-1,3,3,3-Tetrafluoropropene - Wikipedia

   en.wikipedia.org/wiki/Trans-1,3,3,3-tetrafluoro...

   The use of R-134a is being phased out because of its high global warming potential (GWP). HFO-1234ze(E) itself has zero ozone-depletion potential (ODP=0), a very low global warming potential (GWP < 1 ), even lower than CO 2 , and it is classified by ANSI/ASHRAE [ 4 ] as class A2L refrigerant (lower flammability (see below) and lower toxicity).

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

   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 use HFO-1234yf. [ 6 ] Unlike previous vehicular refrigerants, 2,3,3,3‑tetrafluoropropene is flammable , but does not increase fire risk in internal combustion engines .

4. 1,1,2,2-Tetrafluoroethane - Wikipedia

   en.wikipedia.org/wiki/1,1,2,2-tetrafluoroethane

   It is an isomer of the more-used 1,1,1,2-tetrafluoroethane (R-134a). It is used as a foam expansion agent and heat transfer fluid. It is used as a foam expansion agent and heat transfer fluid. [ 3 ]

5. Hydrofluorocarbon - Wikipedia

   They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC refrigerants. In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol ...

6. 1,1,1,2-Tetrafluoroethane - Wikipedia

   en.wikipedia.org/wiki/1,1,1,2-Tetrafluoroethane

   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 ...

9. Chlorofluorocarbon - Wikipedia

   en.wikipedia.org/wiki/Chlorofluorocarbon

   This ruling allows HFO-1234yf to take over in applications where ozone depleting CFCs such as R-12, and high GWP HFCs such as R-134a were once used. [65] The phaseout and replacement of CFCs and HFCs in the automotive industry will ultimately reduce the release of these gases to atmosphere and in turn have a positive contribution to the ...
