List of refrigerants

This is a list of refrigerants, sorted by their ASHRAE-designated numbers, commonly known as R numbers. Many modern refrigerants are man-made halogenated gases, especially fluorinated gases and chlorinated gases, that are frequently referred to as Freon (a registered trademark of Chemours). The R number of a chemical refrigerant is assigned systematically according to molecular structure.

The table is sortable by each of the following refrigerant properties (scroll right or reduce magnification to view more properties):

Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes "R-" or "Refrigerant." Thus, CFC-12 may also be written as R-12 or Refrigerant 12.
An alkene, olefin, or olefine is an unsaturated compound containing at least one carbon-carbon double bond.[65]

Educated Estimates
  1. Some CFCs are assumed to be similar in terms of Semi-Empirical ODP being one.[2][10]
  2. Some HCFCs are assumed to be similar in terms of Semi-Empirical ODP.[2][12]
  3. Some HCFCs are assumed to be similar in terms of Atmospheric Lifetime[1][2] & net GWP over a 100-year time horizon.[1][2]
  4. All HFCs, HFOs, PFCs & PFOs are assumed to be similar in terms of Semi-Empirical ODP being zero.[11][13]
  5. Most hydrocarbons are assumed to be similar to Methane in terms of Atmospheric Lifetime being 12 ± 3 years[1] & Semi-Empirical ODP being < 0(smog chemistry).[17]
  6. Pentane, Isopentane & Ethoxyethane (Diethyl ether) is assumed to have a net GWP over 100-yr to be 4 ± 2.
  7. Air, nitrogen, oxygen & the noble gases are assumed to have an unlimited Atmospheric Lifetime, a Semi-Empirical ODP of zero (except oxygen being slightly less than zero) & net GWP over 100-yr to be zero (except air being the sum of its parts).

In the troposphere and lower stratosphere it induces ozone production via "smog chemistry"(10), while at higher altitudes it causes ozone losses [...] The net effect is generally a gain in column ozone due to methane increases, both in the stratospheric column and total column(11). Thus, unlike for N2O, a calculated ODP for methane would likely be negative.CS1 maint: location (link)
