The invention relates to a vehicle heat pump air conditioner and heat management system and a control method thereof, the system comprises a first heat switch heat exchanger, a stepping motor controls a conveyor belt to drive a rotating shaft to move, a linkage heat insulation device coaxially matched with the rotating shaft is controlled to start and stop, and the start and stop of the heat exchange process are controlled; the second heat switch heat exchanger controls starting and stopping of the heat exchange process through starting and stopping of a vacuum pump. The battery module is coupled with the vehicle heat pump air conditioning system and the battery heat management system through energy storage or energy release; according to the front-back row parallel separation type in-vehicle heat exchanger, cascade heat exchange is achieved between the front-row heat exchanger and the back-row heat exchanger, an ejector is arranged between the front-row heat exchanger and the back-row heat exchanger, and a second expansion valve is adopted as a throttling valve to adjust the pressure of the back-row heat exchanger; the connection of equipment is realized through the connecting pipelines, and the switching of working modes is realized by adjusting different control valves. All-season and all-working-condition efficient and stable operation can be achieved.
