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. Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon. CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a protective layer against UV radiation. THE OZONE LAYER - CFC GASES AND SYMBOLS The ozone layer is extremely important as it protects the earth and its inhabitants from the dangerous ultraviolet rays of the sun.

Undvik tryckprovning med gas (luft) så lång det är möjligt. port av fjärrvärmeledningar med CFC-blåst isoler-. A special numbering system is to be used for fluorinated alkanes, prefixed with Freon-, R-, CFC- and HCFC-, where the rightmost value indicates the number of fluorine atoms, the next value to the left is the number of hydrogen atoms plus 1, and the next value to the left is the number of carbon atoms less one (zeroes are not stated), and the remaining atoms are chlorine. Another group of greenhouse gases includes the chlorofluorocarbons (CFCs). CFCs have been responsible for depleting the ozone layer as they destroy ozone molecules. The ozone layer is a high level Chlorofluorocarbon definition is - any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC. CFCs are gases that were widely used in the past in things such as aerosols and refrigerators and can cause damage to the ozone layer.

The treaty is structured around several groups of halogenated hydrocarbons that deplete stratospheric ozone.

HCFCs, or Hydrochloroflourocarbons, are the close neighbor of CFCs. The main difference between the two types of refrigerant is that HCFCs Chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs.
