Refrigerant is the fluids which complete the thermodynamic cycle of a chiller.It absorbs the heat of the cooled object at low temperatures and then transfers it to the cooling water or air at a higher temperature. In a vapor compression type refrigerator, a refrigerant capable of liquefying at normal temperature or lower temperature is used as a refrigerant such as freon (fluorine, chlorine, bromine derivatives of saturated Hydrocarbons), azeotropic mixture A mixture of Freon in a certain proportion of azeotropic solution), hydrocarbons (propane, ethylene, etc.), ammonia etc.
