COOLING SYSTEM

摘要

A cooling system (1) that cools an HV apparatus (31) includes a compressor (12) that circulates a refrigerant, a heat exchanger (14) that carries out heat exchange between the refrigerant and outside air, an expansion valve (16) that reduces the pressure of the refrigerant, a heat exchanger (18) that carries out heat exchange between the refrigerant and air-conditioning air, a cooling portion (30) that cools, the HV apparatus (31) using the refrigerant that flows between the heat exchanger (14) and the expansion valve (16), a gas-liquid separator (40) that separates the refrigerant that flows between the heat exchanger (14) and the cooling portion (30) into a liquid-phase refrigerant and a gas-phase refrigerant, and a liquid accumulator (70) that is provided between the gas-liquid separator (40) and the cooling portion (30), and that retains the liquid-phase refrigerant separated by the gas-liquid separator (40).

1. A cooling system that cools a heat generation source, comprising:
a compressor that circulates a refrigerant; a first heat exchanger that carries out heat exchange between the refrigerant and outside air; a pressure reducer that reduces a pressure of the refrigerant; a second heat exchanger that carries out heat exchange between the refrigerant and air-conditioning air; a cooling portion that cools the heat generation source using the refrigerant that flows between the first heat exchanger and the pressure reducer; a gas-liquid separator that separates the refrigerant that flows between the first heat exchanger and the cooling portion, into a liquid-phase refrigerant and a gas-phase refrigerant; and a liquid accumulator that is provided between the gas-liquid separator and the cooling portion, and that retains the liquid-phase refrigerant separated by the gas-liquid separator.
