The invention provides a heat pump air conditioning system, a control method and a vehicle. The heat pump air conditioning system comprises an in-vehicle heat pump loop, a motor oil loop, an electric drive cooling liquid loop and a first heat exchanger. The first heat exchanger is provided with a refrigerant inlet and outlet and multiple pairs of heating medium inlets and outlets. The in-vehicle heat pump loop is controlled to communicate with the refrigerant inlet and outlet, and the electric drive cooling liquid loop and the motor oil loop are controlled to communicate with the pair of heating medium inlets and outlets correspondingly, so that heat exchange can be conducted between a refrigerant in the in-vehicle heat pump loop and a heating medium in the electric drive cooling liquid loop and/or a heating medium in the motor oil loop in the first heat exchanger. The in-vehicle heat pump loop can exchange heat with the electric drive cooling liquid loop and the motor oil loop at the first heat exchanger, so that heat in the electric drive cooling liquid loop and the motor oil loop is absorbed, the heat in the electric drive cooling liquid loop and the motor oil loop is used for heating the interior of a vehicle, energy can be effectively saved, and the service life of the vehicle is prolonged. And the heat exchange efficiency is improved.

    本发明提供了一种热泵空调系统、控制方法以及车辆,热泵空调系统包括车内热泵回路、电机油液回路、电驱冷却液回路和第一换热器;第一换热器上设有冷媒进出口以及多对热媒进出口;车内热泵回路受控连通冷媒进出口,电驱冷却液回路与电机油液回路分别受控连通一对热媒进出口,以使车内热泵回路中的冷媒与电驱冷却液回路和/或电机油液回路中的热媒能够在第一换热器中进行热交换。车内热泵回路能够在第一换热器与电驱冷却液回路和电机油液回路进行热交换,从而吸收位于电驱冷却液回路和电机油液回路内的热量,利用电驱冷却液以及电机油液回路中的热量对车内进行加热,从而能够有效节约能量,提高了换热效率。
