They are utilized for the manufacturing of aerosol sprays, blowing agents used for foams and packing materials, solvents, and also as refrigerants. Properties of CFC’s .

HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. We find pronounced seasonal variations of global emissions for these two major refrigerants, with summer emissions two to three times higher than in CFCs were widely used in four areas: aerosol propellants, solvents in the cleaning of electronic components and metals, refrigerants, and the blowing agents in  Chlorofluorocarbons (CFCs) are artificially made chemical compounds used as refrigerants, cleaning solvents, aerosol propellants, and blowing agents for foam   Chlorofluorocarbons are more commonly referred to as CFCs or, when used for refrigeration, CFCs are also known as freon. Developed in the 1930s as a safe  CFC-12 (also called Freon or R-12) has been the coolant most frequently used in automobile A/C systems and accounted for 20 percent of all U.S. CFC  Chlorofluorocarbons are a family of halocarbons that contain only carbon, chlorine & fluorine. Used in blowing plastics & fridges. CFCs destroy the ozone layer.

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms. Gases such as CFC’s had damaged the ozone layer, creating a huge hole through which dangerous ultraviolet light could penetrate. Where the hole in the ozone layer developed, these dangerous rays penetrated and reached the earths surface.

Nowadays  CFCs (chlorofluorocarbons) are a group of gases that were widely used in refrigeration systems and aerosols, among other things because of their high stability  CFCs reach the stratosphere because the Earth's atmosphere is always in motion and mixes the chemicals added into it. CFC molecules are indeed several  “The refrigerators are chlorofluorocarbon (CFC) free. HFC-134a, the gas commonly used in refrigeration gas, is ozone depleting,” says Vijay Crishna,  Chlorofluorocarbons (CFCs) are an important example of a chlorine-containing source gas. Emitted source gases accumulate in the lower atmosphere (  During the past few decades, several heat-trapping gases have been abbreviated CH4, nitrous oxide, or N2O for short, and the chlorofluorocarbons, known as Methane is the same natural gas that we use at home for cooking and heatin 22 May 2019 CFC-11 was widely used in the 1970s and 1980s as a refrigerant and to make foam insulation.

R-12 was primarily used for automobiles and other mobile air conditioning. R-12’s reign ended after nearly eighty years as a mainstream refrigerant. In 1994 R-12 was phased out across the United States. R-22 soon followed suit and in 2010 R-22 was no longer allowed to be used in any new machines.
