The role of refrigerant in the air-cooled chiller

The refrigerant itself circulates continuously in the refrigeration system, and then realizes refrigeration through its own state changes. The refrigerant absorbs the heat of the cooling medium in the evaporator and vaporizes, and transfers the heat to the surrounding air or water in the condenser to condense.
