AUTOMOBILE, HEAT PUMP AIR CONDITIONING SYSTEM, AND AUTOMOBILE HEAT PUMP AIR CONDITIONING ASSEMBLY AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2019/029092

A1

An automobile, a heat pump air conditioning system, and an automobile heat pump air conditioning assembly and a control method therefor, comprising a compressor (11), an in-vehicle heat exchanger, and an out-vehicle heat exchanger (22). The in-vehicle heat exchanger comprises a refrigerating heat exchanger (16) and a heating heat exchanger (15), and further comprises a heating start shielding branch circuit; one end of the heating start shielding branch circuit is in communication with a liquid inlet pipe of the heating heat exchanger (15), and the other end thereof is in communication with a liquid outlet pipe of the heating heat exchanger (15); and a heating start two-way valve (27) for controlling the on-off of the heating start shielding branch circuit is disposed on the heating start shielding branch circuit. By means of the heat pump air conditioning system, the exhaust temperature and exhaust pressure of the compressor (11) can be rapidly increased within a short time. Therefore, the heat pump air conditioning system can achieve the heating requirements within a short time; this satisfies the requirement of rapidly increasing the temperature in an automobile at a low temperature.
