COOLING SYSTEM

摘要

A cooling system (1) that cools HV equipment (31) includes a compressor (12) that circulates refrigerant, a condenser (14) that condenses the refrigerant, a gas-liquid separator (40) that stores the refrigerant in liquid form that is condensed by the condenser (14), an expansion valve (16) that reduces a pressure of the refrigerant, an evaporator (18) that vaporizes the refrigerant that is reduced in pressure by the expansion valve (16), a first passage (23) and a second passage (34, 36, 32) through which the refrigerant flows from the gas-liquid separator (40) toward the expansion valve (16), and that are provided in parallel, and a cooling portion (30) that is provided along the second passage and cools the heat source (31) using the refrigerant. The refrigerant in liquid form flows from the gas-liquid separator (40) through the second passage.
