A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. R410A R134A R32 WHAT IS CFC's REFRIGERANT ? • CFC's refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. • Common CFC's refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. WHAT IS HCFC's REFRIGERANT ? Hydrochlorofluorocarbons, or HCFC's, are chemicals that are mainly used as refrigerants. ⚫ Unfortunately, releases of HCFC's deplete the Earth's protective ozone layer and contribute to climate change. • R-22 is an HCFC's refrigerant that is often used in air- conditioning equipment. NECESSITY FOR REPLACEMENT OF CFC's /HCFC's REFRIGERANT CFC's/HCFC's are powerful green house gases. This Refrigerant causes GLOBAL WARMING. CFC's/HCFC's destroy
