The invention relates to a heat pump air conditioning system, a control method thereof and a vehicle. The heat pump air-conditioning system comprises a refrigerant subsystem, the refrigerant subsystem comprises a compressor, a front air-conditioning box body, a reversing valve group, a first throttling component and an outside-vehicle heat exchanger which are connected through a refrigerant pipeline, a first heat exchanger and a second heat exchanger are arranged in the front air-conditioning box body, and a temperature air door is arranged between the first heat exchanger and the second heat exchanger in a blocking mode; an air outlet of the compressor is connected with an inlet of the first heat exchanger; the reversing valve set is provided with four connecting ports, the first connecting port is connected with an outlet of the first heat exchanger, the second connecting port is connected with the second heat exchanger, the third connecting port is connected with the outside-vehicle heat exchanger, and the fourth connecting port is connected with an air return port of the compressor. The first throttling component is connected between the second heat exchanger and the external heat exchanger. In this way, the requirement for multiple functions can be met through the simple pipeline structure, the structure of the heat pump air conditioning system is simplified, and cost is reduced.
