Patent attributes
An automotive air conditioning system includes a compressor, a first heat exchanger, a first pump, a first combined valve, a second combined valve, an outdoor heat exchanger, a second heat exchanger and a battery unit. In a first cooling mode, the compressor, the outdoor heat exchanger, the first combined valve and the first heat exchanger communicate in sequence to form a circuit, while the first pump, the first heat exchanger and the second heat exchanger communicate to form another circuit. In a first heating mode, the compressor, the first heat exchanger, the second combined valve and the outdoor heat exchanger communicate in sequence to form a circuit, while the first pump, the first heat exchanger and the second heat exchange communicate in sequence to form another circuit. Thermal management of the battery unit can be made by interacting with the first cooling mode or the first heating mode.
