The invention relates to the technical field of heat pump air conditioners, in particular to a passenger car heat pump air conditioning system and a control method. The passenger car heat pump air conditioning system mainly comprises an outdoor heat exchange module and an indoor heat exchange module. Wherein the outdoor heat exchange module comprises a serial sheet type heat exchanger, a compressor and a four-way reversing valve; the four-way reversing valve is provided with a port a, a port b, a port c and a port d; one end of the compressor is communicated with the port a, and the other end is communicated with the port c of the four-way reversing valve. The indoor heat exchange module comprises a tubular heat exchanger and a parallel flow heat exchanger, the tubular heat exchanger is communicated with the parallel flow heat exchanger, one end of the serial heat exchanger is communicated with the port b, the other end of the serial heat exchanger is communicated with the parallel flow heat exchanger, and the port d is simultaneously communicated with the tubular heat exchanger and the parallel flow heat exchanger. The heat pump air-conditioning system for the passenger car can prevent the phenomenon of frosting on the serial sheet type heat exchanger, the tubular heat exchanger and the parallel flow heat exchanger, the heat exchange efficiency of the heat pump air-conditioning system for the passenger car is improved, and the cost is saved.
