What material does central air conditioner use in general?
According to the condensing pressure, refrigerants can be divided into three types: high temperature (low pressure) refrigerants, medium temperature (medium pressure) refrigerants and low temperature (high pressure) refrigerants.
According to the chemical composition of the refrigerant can be divided into five categories: inorganic compound, refrigerant freon, saturated hydrocarbon refrigerant, unsaturated hydrocarbon refrigerant and azeotropic mixture refrigerant.
The refrigerant is widely used in the compression of the refrigerant is ammonia, freon and hydrocarbon.
