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 loop and a water loop, wherein the water loop comprises a battery heat dissipation water loop, a motor heat dissipation water loop and a condenser heat dissipation water loop; the refrigerant loop comprises a compressor, a water-cooled condenser and a battery cooler which are connected in sequence; the battery cooler is simultaneously connected into the battery heat dissipation water loop and is used for transferring the cooling capacity generated by the refrigerant loop into the battery heat dissipation water loop; the water-cooling condenser is connected into the condenser heat dissipation water loop and used for transferring heat generated by the refrigerant loop into the condenser heat dissipation water loop; a water-water heat exchanger is connected in the condenser heat dissipation water loop and the motor heat dissipation water loop, in a fast charging mode, heat of the condenser heat dissipation water loop is transferred into the motor heat dissipation water loop through the water-water heat exchanger, at the moment, the motor does not work and has no heat dissipation requirement, and therefore the condensation capacity of the water-cooling condenser is improved, and the service life of the water-cooling condenser is prolonged. And the requirement for large refrigerating capacity in the quick-charging mode is met.
