This is a list of refrigerants, sorted by their ASHRAE-designated numbers, commonly known as R numbers. Many modern refrigerants are human-made halogenated gases, especially fluorinated gases and chlorinated gases, that are frequently referred to as Freon (a registered trademark of Chemours).
According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon-carbon multiple bonds, there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next. If there is more than one carbon atom but no multiple bonds, there are three digits, and the number of carbon atoms minus one is the first digit. If there is only one carbon atom, then there are only two digits. The last two digits are always the number of hydrogen atoms plus one (H+1), followed by the number of fluorine atoms. Any other atoms attached to the carbons are assumed to be chlorine atoms. For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This basic scheme is modified as follows:
There are separate numbering schemes for zeotropic and azeotropic blends, organic chemicals which don't fit into the scheme above, and inorganic chemicals:
The table is sortable by each of the following refrigerant properties (scroll right or reduce magnification to view more properties):
Since over 100,000 refrigerant blends are possible, [2] this list should only have notable refrigerants and refrigerant blends.

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.

Methane's influence on ozone is very dependent on altitude. 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.
