VEHICULAR HEAT MANAGEMENT SYSTEM

WIPO Patent Application WO/2023/286349

A1

This vehicular heat management system is provided with: a first refrigerant circuit 1 that is for conditioning air in a vehicle cabin and that has an indoor air cooler 16 in which heat is exchanged between a first refrigerant and indoor air; a cooling water circuit 2 that has a radiator 22, and cools an electrical part 21 using cooling water; a second refrigerant circuit 3 that is for regulating the temperature of a battery and that has a second refrigerant/outdoor air heat exchanger 32 in which heat is exchanged between a second refrigerant and outdoor air; a first refrigerant/cooling water heat exchanger 4; and a second refrigerant/cooling water heat exchanger 5. In a vehicle cabin-cooling water-cooling mode in which the vehicle cabin is cooled and cooling water is cooled, heat is absorbed from indoor air by the first refrigerant of the first refrigerant circuit 1 in the indoor air cooler 16, heat is released from the cooling water of the cooling water circuit 2 to outdoor air through the radiator 22, heat is released from the second refrigerant of the second refrigerant circuit 3 to outdoor air in the second refrigerant/outdoor air heat exchanger 32, and heat is absorbed from the cooling water of the cooling water circuit 2 in the second refrigerant/cooling water heat exchanger 5.
