ON-VEHICLE AIR CONDITIONING SYSTEM HAVING BATTERY HEATING FUNCTION

WIPO Patent Application WO/2022/070795

A1

This on-vehicle air conditioning system has a vehicle interior heating circuit that includes a first pump and a radiator. The on-vehicle air conditioning system has a battery heating circuit that includes a second pump and a battery heat exchange device. The on-vehicle air conditioning system has a first bypass and a second bypass. The first bypass is connected to the vehicle interior heating circuit at a first split node and is connected to the battery heating circuit at a first merge node. At at least one location arbitrarily selected from the first and second split nodes and the first and second merge nodes is provided a three-way flow rate adjustment valve which adjusts the flow rate of a cooling liquid that flows into and out of the first bypass or second bypass. At least one of the vehicle interior heating circuit and the battery heating circuit includes a heat source. At at least one location arbitrarily selected from the first and second split nodes and the first and second merge nodes is provided a three-way flow rate adjustment valve which adjusts the flow rate of a cooling liquid that flows into and out of the first bypass or second bypass.
