Because they contain hydrogen, HCFCs break down more easily in the atmosphere than do CFCs. Therefore, HCFCs have less ozone depletion potential, in addition to less global-warming potential. HFCs do not contain chlorine and do not contribute to destruction of stratospheric ozone.
What is difference between CFC and HFC?
HFCs are used as refrigerant to promote cooling in appliances such as refrigerators and air conditioners. Decades ago, appliances used chlorofluorocarbons (CFCs) as refrigerants, which wreaked havoc on the ozone layer and were phased out after the 1987 Montreal Protocol.
Did HFCs replace CFCs?
HFCs, which originally were developed to replace CFCs and HCFCs, also absorb and trap infrared radiation or heat in the lower atmosphere of the earth. HFCs, CFCs and HFCs are a subset of a larger group of climate changing gases called greenhouse gases (GHGs).
