Worldwide production of R-22 in 2008 was about 800 Gg per year, up from about 450 Gg per year in 1998. R-438A (MO-99) is a R-22 replacement. [71] R-123 HCFC-123 CHCl 2 CF 3: 2,2-Dichloro-1,1,1-trifluoroethane: 292 79 US phase-out Used in large tonnage centrifugal chiller applications.
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.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
