A commonly-used refrigerant in a Vapour Cycle Air Conditioning System is…
REFRIGERANT
For many years, dichlorodifluoromethane (under the brand name Freon-12/R12) was the standard refrigerant used in aircraft vapor cycle air conditioning systems. Some of these systems remain in use today. R12 was found to have a negative effect on the environment; in particular, it degraded the earth’s protective ozone layer. In most cases, it has been replaced by tetrafluoroethane (R134a), which is safer for the environment.
