Role of refrigerants

The role of the refrigerant is to play in the refrigeration system gasification and heat absorption and condensation of exothermic thermal cycle to achieve the purpose of refrigeration. Specifically, the refrigerant is a refrigerant system can be evaporated in the evaporator and from the cooled object to absorb heat and gasification, and then in the condenser will be the heat transfer to the surrounding medium (water or air) and its own liquefaction of the working material, also known as the work material.

Because of the different technical parameters of different refrigerants, so, different refrigeration systems will use different kinds of refrigerants.
