Title:
VALVE CONTROL DEVICE, COOLING DEVICE, VALVE CONTROL METHOD, AND PROGRAM STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/131555
Kind Code:
A1
Abstract:
Provided is a valve control device 1 that suppresses shortening of the lifespan of a valve without incurring a reduction in cooling efficiency, the valve control device comprising a receiving unit 2, an opening degree control unit 3, and a fixing control unit 4. The receiving unit 2 receives information concerning the measured temperature of a fluid to be cooled that is cooled by a vaporizer in a refrigerant circulation path that is equipped with: the vaporizer that cools the fluid to be cooled through exchange of heat between the fluid to be cooled and a refrigerant; and a condenser that causes heat to be released from the refrigerant. The opening degree control unit 3 variably controls the opening degree of a valve that is provided along the circulation path and controls the flow rate of the refrigerant that circulates through the circulation path in accordance with the difference between the measured temperature and a target temperature provided in advance. The fixing control unit 4 fixes the opening degree of the valve with priority over variable control performed by the opening degree control unit 3 in the case where a fixing condition based on the difference between the measured temperature and the target temperature and a valve opening degree variation condition is satisfied.
