The invention relates to a vehicle heat pump air conditioning system and a control method thereof, the system comprises a refrigerant circulation loop, a secondary refrigerant circulation loop, a battery cooling liquid circulation loop and a heat exchange air duct, a heat switch heat exchanger of the refrigerant circulation loop, a battery module and a heat regenerator are connected to form a first fluid channel and a second fluid channel for heat exchange; the first fluid channel and the second fluid channel form a refrigerant passage between the compressor and the front and rear rows of parallel and separated out-of-vehicle heat exchangers; the heat regenerator is communicated with a water-cooling heat exchanger in a secondary refrigerant circulation loop, an in-vehicle heat exchanger is arranged in the secondary refrigerant circulation loop and arranged in a heat exchange air duct, fresh air is preheated through waste heat of the battery module, and then the fresh air is mixed with return air to be subjected to secondary heating through the in-vehicle heat exchanger; the battery cooling liquid circulation loop is provided with a battery heat exchanger communicated with the battery module, and the battery heat exchanger is communicated with a heat exchange working medium of the in-vehicle heat exchanger. Switching of different working modes can be achieved, and the heat exchange efficiency and the extremely cold heating COP are improved.
