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):

• Type/Prefix (see legends)
• ASHRAE number
• IUPAC chemical name
• molecular formula
• CAS registry number / Blend Name
• Atmospheric Lifetime in years
• Semi-Empirical Ozone depletion potential
• net Global warming potential over a 100-year time horizon
• Occupational exposure limit/Permissible exposure limit in parts per million (volume per volume) over a time-weighted average (TWA) concentration for a normal eight-hour work day and a 40-hour work week
• ASHRAE 34 Safety Group in Toxicity & Flammability (in Air @ 60 °C & 101.3 kPa) classing (see legends)
• Refrigerant Concentration Limit / Immediately Dangerous to Life or Health in parts per million (volume per volume) & grams per cubic meter
• Molecular mass in Atomic mass units
• Normal Boiling Point (or Bubble & Dew Points for the Zeotrope(400)-series)(or Normal Boiling Point & Azeotropic Temperature for the Azeotrope(500)-series) at 101,325 Pa (1 atmosphere) in degrees Celsius
• Critical temperature in degrees Celsius
• Critical pressure (absolute) in kiloPascals

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)
