2. 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 ...

   en.wikipedia.org/wiki/List_of_refrigerants

   For an oxygen-containing refrigerant (an ether), the prefixed capital letter "E" is used. [1]: §4 There are separate numbering schemes for zeotropic and azeotropic blends, organic chemicals which don't fit into the scheme above, and inorganic chemicals: Zeotropic blends are numbered starting with 400.

4. Freon - Wikipedia

   en.wikipedia.org/wiki/Freon

   'Freon' is the brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of this type. They emit a strong smell similar to acetone. [2] Freon has been found to cause damage to human health when inhaled in large amounts.

   A DuPont R-134a refrigerant. A refrigerant is a working fluid used in cooling, heating or reverse cooling and heating of air conditioning systems and heat pumps where they undergo a repeated phase transition from a liquid to a gas and back again.

6. 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 ]

7. Dichlorodifluoromethane - Wikipedia

   en.wikipedia.org/wiki/Dichlorodifluoromethane

   Automobile manufacturers began phasing in R-134a around 1993 [citation needed]. When older units leak or require repair involving removal of the refrigerant, retrofitment to a refrigerant other than R-12 (most commonly R-134a) is required in some jurisdictions. The United States does not require such conversion.

9. 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.
