METHOD FOR CONTROLLING HEAT EXCHANGE DEVICE, HEAT EXCHANGE DEVICE, WATER-COOLED HEAT PUMP HEATING AND COOLING DEVICE, AND WATER-COOLED HEAT PUMP DEVICE

摘要

A heat transfer medium liquid circulation flow channel having a first heat exchange unit exchanging heat to a second heat exchange unit is provided, and a fixed amount of first heat transfer medium liquid circulates therein. A feed pipe couples heat source holding second heat transfer medium liquid having temperature difference from the first medium liquid to the heat transfer medium liquid circulation flow channel. The feed pipe is coupled to an inlet end side of the first heat exchange unit and a discharge pipe is coupled to an outlet end side thereof. A necessary amount of second medium liquid is supplied to the inlet end side via the feed pipe so that a detected temperature of the first medium liquid in the outlet end maintains required set temperature. The same amount of the first medium liquid as the supplied second medium liquid is discharged out of the discharge pipe.
