The invention relates to the technical field of air conditioning systems, in particular to a heat pump automobile air conditioner and a heating method.The heat pump automobile air conditioner comprises a fresh air duct and an air return duct, the front end of the fresh air duct communicates with the outside of a passenger compartment, the rear end of the fresh air duct communicates with an air inlet of a mixed air duct, and an air outlet of the mixed air duct communicates with the inside of the passenger compartment; the air conditioner further comprises a heat pump system, a refrigerant in the heat pump system is R744, and the heat pump system comprises an air cooler which is arranged in the fresh air duct and used for heating air. The air return ducts comprise the first air return duct and the second air return duct. An air inlet of the return air duct I is communicated with the passenger compartment, and an air outlet is communicated with the mixed air duct; an air inlet of the second air return duct communicates with the passenger compartment, and an air outlet of the second air return duct communicates with the fresh air duct and is located on the front side of the air cooler. A fresh air valve is arranged at the position, located on the front side of an air outlet of the second return air duct, in the fresh air duct. A return air valve is arranged in the return air duct II; the device is high in efficiency and low in energy consumption.
