Chlorofluorocarbons (CFCs) are commonly used as refrigerants in air conditioners in daily life, but previously used CFCs will destroy the ozone layer, and scientists have developed CFCs that will not destroy the ozone layer.
The ideal refrigerant is non-toxic, non-explosive, non-corrosive to metals and nonmetals, non-flammable, easy to be found when leaking, stable in chemical properties, non-destructive to lubricating oil, high in latent heat of evaporation and harmless to the environment.

Refrigerant is used to transfer heat energy in refrigeration and air conditioning system to produce refrigeration effect. Refrigerant is an intermediate substance in the refrigeration process. It first accepts the cooling capacity of the refrigerant and cools down, and then cools other cooled substances. We call this intermediate substance a refrigerant. Also known as coolant.
Water and air are commonly used refrigerants in air conditioning engineering. In our daily life, refrigerators, freezers, commercial cold storage, etc. , all rely on air as refrigerant, in the process of circulating refrigeration, the cold energy in the refrigeration process is transferred to the food, so that the food is frozen in the freezer (or freezer).
In the air conditioning system, the refrigerant entering the evaporator evaporates and absorbs heat through the operation of the refrigeration unit. When cold water enters the evaporator, the heat is rapidly exchanged in the evaporator, and the heat is absorbed by the refrigerant, and the temperature drops, becoming frozen water. Then the chilled water exchanges heat with the treated air through the surface cooler in the air conditioning equipment, so as to reduce the air temperature.
