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): 
<br> Since over 100,000 refrigerant blends are possible, this list should only have notable refrigerants and refrigerant blends.
Type and flammability.
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.<br>An alkene, olefin, or olefine is an unsaturated compound containing at least one carbon-carbon double bond.
