A Complete Mechanical Guide to Secondary Refrigerants (PDF)
Secondary refrigerants are liquids which are being used in an air conditioning system. The prime purpose of secondary refrigerant is to transfer heat from material that is being cooled; to the heat exchanger where heat is absorbed by the primary refrigerant. Chilled water is being used as a secondary refrigerant in high-temperature applications. Brines, glycols, and oils are used as secondary refrigerants in low-temperature applications. Secondary refrigerants are used as the transportation medium of cooling capacity in large air refrigeration plants. Secondary refrigerants have properties such as non-corrosive, inexpensive, high specific heat, excellent heat transfer characteristics, chemically stable, low viscosity, etc. Secondary refrigerants such as calcium chloride brine, propylene glycol, etc. are applied in different low-temperature applications like industrial refrigeration, commercial refrigeration, heat pumps, and others.
