   en.wikipedia.org/wiki/Automotive_air_conditioning

   The third and newest automotive air conditioning refrigerant is R-1234yf. R-1234yf is a hydrofluoroolefin refrigerant that contains hydrogen, fluorine, and also carbon elements. The refrigerant was developed by the DuPont/Honeywell company and is more expensive per pound than R-134a.

4. Refrigerant - Wikipedia

   en.wikipedia.org/wiki/Refrigerant

   From 2011 the European Union started to phase out refrigerants with a global warming potential (GWP) of more than 150 in automotive air conditioning (GWP = 100-year warming potential of one kilogram of a gas relative to one kilogram of CO 2) such as the refrigerant HFC-134a (known as R-134a in North America) which has a GWP of 1526.

5. 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.

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

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

   1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners.These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12.

7. R-410A - Wikipedia

   en.wikipedia.org/wiki/R-410A

   R-410A is a refrigerant used in air conditioning and heat pump applications. It is a zeotropic but near-azeotropic mixture of difluoromethane (CH 2 F 2, called R-32) and pentafluoroethane (CHF 2 CF 3, called R-125). R-410A is sold under the trademarked names AZ-20, EcoFluor R410, Forane 410A, Genetron R410A, Puron, and Suva 410A.

8. Dichlorodifluoromethane - Wikipedia

   en.wikipedia.org/wiki/Dichlorodifluoromethane

   R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1,1,1,2-tetrafluoroethane (R-134a), which has an insignificant ozone depletion potential. Automobile manufacturers began phasing in R-134a around 1993 [citation needed].
