Title:
HEAT MANAGEMENT SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/286348
Kind Code:
A1
Abstract:
The present invention is provided with: a first refrigerant circuit 1 for cabin-interior air conditioning, which has a first refrigerant/internal air heat exchanger 12 for exchanging heat between a first refrigerant and indoor air; a cooling water circuit 2 for cooling an electrical component 23 with cooling water; a second refrigerant circuit 3 for battery temperature regulation, which has a battery heat exchanger 38 for exchanging heat between a second refrigerant and a battery; a first refrigerant/cooling water heat exchanger 4; and, a second refrigerant/cooling water heat exchanger 5. In a mode for battery cooling and cooling water heat storage activated during charging of the battery, the second refrigerant absorbs heat from the battery in the battery heat exchanger and dissipates heat to the cooling water in the second refrigerant/cooling water heat exchanger to maintain the temperature of the cooling water within a prescribed range in the cooling water circuit 2. In the first refrigerant circuit in a cabin interior heating mode, the first refrigerant absorbs heat from the cooling water in the first refrigerant/cooling water heat exchanger 4 and dissipates heat to indoor air in the first refrigerant/internal air heat exchanger 12.
