The invention relates to a heat pump air conditioning system integrated with a waste heat recovery function and a control method. Wherein the heat pump air-conditioning system comprises an electric air-conditioning compressor, a gas-liquid separator, an auxiliary heating PTC (Positive Temperature Coefficient), a throttling short pipe, an air blower, an out-of-vehicle heat exchanger, a waste heat recovery heat exchanger, an in-vehicle heat exchanger, an in-vehicle evaporator, a power battery heat exchanger, an out-of-vehicle radiator, four electromagnetic valves, three electronic expansion valves, an electronic three-way water valve and a five-way valve. According to the technical scheme, the use environment temperature range of the heating function of the heat pump air conditioning system is widened; and by controlling the opening degree of the external heat exchanger electronic expansion valve and the opening degree of the internal heat exchanger electronic expansion valve, waste heat recycling is maximized, and the heating effect of the heat pump air conditioner is improved.
