Explanation

Sulphur dioxide gas was used in refrigerator as refrigerant in previous years. Halogenated hydrocarbons are frequently used as refrigerant in refrigerator. Methyl chloride is used in refrigerator as refrigerant. A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane. They are also commonly known by the DuPont brand name Freon. The most common representative is dichlorodifluoromethane (R-12 or Freon-12). Many CFCs have been widely used as refrigerants, propellants (in aerosol applications), and solvents.
