What kind of refrigerants are classified as CFCs?

Chlorofluorocarbons, commonly referred to as CFCs, are a group of man-made organic compounds that contain chlorine, fluorine, and carbon. They were once widely used in refrigeration, aerosol propellants, and other applications due to their stability and efficiency in heat transfer. However, CFCs are known to contribute to ozone depletion in the stratosphere, leading to the eventual phase-out of these substances under international agreements.

The classification as CFCs is specifically tied to the presence of chlorine in their chemical structure, which distinguishes them from other types of refrigerants. Hydrofluorocarbons, perfluorocarbons, and ammonia-based refrigerants do not contain chlorine and thus do not fall into the CFC category. Hydrofluorocarbons are often considered a replacement for CFCs but still pose environmental concerns due to their global warming potential. Perfluorocarbons are another category of compounds that, while they do contain fluorine and carbon, lack chlorine and thus are not classified as CFCs. Ammonia-based refrigerants are entirely different, utilizing ammonia as the primary refrigerant and are known for being more environmentally friendly in terms of ozone depletion but have different chemical
