HEAT EXCHANGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a heat exchange system capable of increasing a temperature difference even when a underground heat source is used, using it for a high purity water using potable water, using in a large quantity at a low cost and obtaining a refrigerant having good thermal efficiency with the high purity water used as the refrigerant. SOLUTION: The heat exchange system heat exchanges by the refrigerant flowing to a circuit between heat exchangers for conducting a thermal work by using the heat source such as a geothermal heat or the like or/and a circuit between the exchanger and an air conditioner. The refrigerant is made in high purity so that the refrigerant can flow even by supercooling a fluid used as the refrigerant. The refrigerant is supplied to the circuit in high purity by treating the potable water to high purity by a high purity treating means.
