It is used where low freezing point and non-corrosive properties are important. It is used for most of the applications. Air- CFCs, or Chlorofluorocarbons, are the original refrigerant. They consist of Carbon, Chlorine, and Fluorine. When you hear someone say ‘Refrigerant,’ they are referring to CFCs. HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs.

HCFC-141b - Used in insulating foam post 1994 - Used as the predominant refrigerant domestic systems. Eliminated in 2003. CFCs are much more potent on a per molecule basis than CO2 and some other greenhouse gases, even though the emissions of those gases are larger than CFC emissions by several orders of magnitude. By simply replacing the CFCs with hydrochlorofluorocarbons (HCFCs) or hydrofluorocarbons (HFCs), the proportional global warming impact of these chemical emissions in the future would change as For example, CFC-R12 has a lifetime of approximately 100 years, while other CFCs can last from 45 to 1700 years.

The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, sulfur dioxide, methyl chloride, or propane, that could result in fatal accidents when they leaked. In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12).
