The invention relates to the technical field of heat pump air conditioners, in particular to a new energy automobile heat pump air conditioning system which comprises a compressor, a PTC heating unit, a control valve, a condenser, a throttler, an evaporator and a gas-liquid separator which are sequentially connected through a pipeline, and the outlet end and the inlet end of the compressor communicate with the PTC heating unit and the gas-liquid separator correspondingly. The control valve comprises a first connector, a second connector, a third connector and a fourth connector, when the first connector is communicated with the second connector, and the third connector is communicated with the fourth connector, the control valve is in a heating mode, the first connector is communicated with the third connector, the second connector is communicated with the fourth connector, and the control valve is in a refrigerating mode. A refrigerant can be directly heated through the PTC heating unit, so that the auxiliary heating effect on the air conditioner heat pump system is achieved, and the heat pump air conditioner system rapidly enters a stable working state.
