2. Chlorodifluoromethane - Wikipedia

   en.wikipedia.org/wiki/Chlorodifluoromethane

   Hydrofluorocarbons (HFCs) are often substituted for R-22 because of their lower ozone depletion potential, but these refrigerants often have a higher GWP. R-410A, for example, is often substituted, but has a GWP of 2088. Another substitute is R-404A with a GWP of 3900. Other substitute refrigerants are available with low GWP.

3. R-407C - Wikipedia

   en.wikipedia.org/wiki/R-407C

   R-407C is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. [ 1 ]

4. R-406A - Wikipedia

   en.wikipedia.org/wiki/R-406A

   This refrigerant was designed as a drop-in replacement for dichlorodifluoromethane (R-12) which is compatible with the typical mineral oil lubricants used in R-12 systems. Since it is a zeotropic mixture , it has a range of boiling points which may increase the effectiveness of the heat transfer elements in refrigeration equipment.

5. HC-12a - Wikipedia

   en.wikipedia.org/wiki/HC-12a

   HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a [1] and Hydrocarbon Blend B, is marketed as a "drop-in" replacement refrigerant for R-12 and other refrigerants. HC-12a is a mixture of hydrocarbons, specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting. The hydrocarbon blend is compatible ...
