COOLING DEVICE AND CONTROL METHOD FOR COOLING DEVICE

摘要

A cooling device capable of achieving cooling performance suitable for an amount of generated heat from a heat source is provided. A cooling device (1) cooling HV equipment (31) includes a compressor (12) for circulating a coolant; a heat exchanger (14) performing heat exchange between the coolant and outside air; an expansion valve (16) decompressing the coolant; a heat exchanger (18) performing heat exchange between the coolant and air-conditioning air; a cooling unit (30) provided on a route of the coolant flowing between the heat exchanger (14) and the expansion valve (16), and cooling the HV equipment (31) using the coolant; a bypass route (41) bypassing the expansion valve (16) and the heat exchanger (18); and a switching valve (52) selectively switching between a flow of the coolant flowing from the cooling unit (30) toward the expansion valve (16) and a flow of the coolant flowing through the bypass route (41).
