COOLING DEVICE
Document Type and Number:
Japanese Patent JP2014231961
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling device capable of constantly securing cooling efficiency of a heating source.SOLUTION: A cooling device 1 for cooling EV equipment 31, includes a compressor 12 in which a refrigerant is circulated, heat exchangers 14, 15 connected in series to condense the refrigerant, an expansion valve 16 for decompressing the refrigerant, a cooling portion 30 connected between the heat exchangers 14, 15 to cool the EV equipment 31 by using the refrigerant, a switch valve 50 switching the refrigerant flow from the heat exchanger 14 toward the cooling portion 30 and the refrigerant flow from the heat exchanger 14 to the expansion valve 16, and a control portion. The control portion adjusts an operating condition of the compressor 12 in switching to the setting for allowing the refrigerant to flow from the heat exchanger 14 to the expansion valve 16, from the setting for allowing the refrigerant to flow from the heat exchanger 14 to the cooling portion 30, to operate the switching valve 50 thereafter.
