Temperature controller of liquid cooling system.

摘要

There is disclosed a temperature controller for controlling a coolant temperature in a liquid cooling system comprising a liquid circulation circuit in which coolant for cooling a machine circulates and a refrigeration circuit for cooling the coolant. More specifically, when the operating capacity of a compressor of the refrigeration circuit is variably adjusted by an inverter and when the operating condition of the machine is changed, its frequency value is varied in accordance with the change, so that it is possible to immediately correspond to the change of a liquid temperature to be generated in the future. In addition, an appropriate control can be selected as a control varying the frequency in combination with a normal feedback control, wherein the liquid temperature may converge on a set value or it may be co-changed to a room temperature or the like.
