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.
: 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, 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. The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs.

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. This lesson covers the properties and uses of CFCs and will explain some of the unintended consequences of CFCs.
