Abstract

A cooling system that cools HV equipment includes a compressor that circulates refrigerant, a condenser that condenses the refrigerant, a gas-liquid separator that stores the refrigerant in liquid form that is condensed by the condenser, an expansion valve that reduces a pressure of the refrigerant, an evaporator that vaporizes the refrigerant that is reduced in pressure by the expansion valve, a first passage and a second passage through which the refrigerant flows from the gas-liquid separator toward the expansion valve, and that are provided in parallel, and a cooling portion that is provided along the second passage and cools the heat source using the refrigerant. The refrigerant in liquid form flows from the gas-liquid separator through the second passage.
