The invention belongs to the field of automobile air conditioners, and relates to an automobile heat pump air conditioning system with a waste heat recovery device. The automobile heat pump air conditioning system comprises a refrigerant loop and a cooling liquid loop connected to the refrigerant loop in parallel, wherein the refrigerant loop comprises an electric compressor, a water-cooled condenser, an external condenser, an evaporator and a gas-liquid separator which are connected in sequence; and the cooling liquid loop is connected to the water-cooled condenser in parallel and comprises awater tank and a warm air core body. The automobile heat pump air conditioning system further comprises a waste heat recovery system connected to the refrigerant loop in parallel, wherein the waste heat recovery system comprises a waste heat recovery device, two branches are arranged on the waste heat recovery device, the waste heat recovery device is connected to the external condenser in parallel through the first branch, and the second branch is connected to a water pump and a low-temperature radiator and flows back to the waste heat recovery device; and the position of the low-temperatureradiator is matched with the position of the external condenser. The waste heat recovery device can be used as a condenser or an evaporator, the proportion of the air conditioning system can be reduced, and the energy consumption of the whole vehicle is reduced.
