The invention provides a new energy automobile heat pump air conditioning system which comprises an electric scroll compressor, an automobile indoor heat exchanger, an automobile outdoor heat exchanger, a flash evaporator and a four-way reversing valve, the electric scroll compressor is connected with the flash evaporator, an air supplementing cavity is formed in the middle of the electric scroll compressor, one or more air supplementing holes are formed in the surface of the air supplementing cavity in a penetrating mode, the air supplementing cavity is outwards connected with an air suction pipeline at the air supplementing hole, the other end of the air suction pipeline is connected with an air pump, and a pressure sensor is arranged on the air suction pipeline. The air supplementing cavity is formed in the middle of the electric scroll compressor, the pressure in the air supplementing cavity is monitored in real time through the pressure sensor on the air suction pipeline, real-time supplementing is carried out, the exhaust temperature of the electric scroll compressor is reduced, the mass flow rate of a refrigerant is increased, and the economical efficiency of refrigeration and heating of the air conditioning system is improved; the air conditioning system cools exhaust gas of the electric scroll compressor through medium-temperature medium-pressure refrigerant gas flowing out of the flash evaporator, and the heating effect of the air conditioning system in a low-temperature environment is achieved.
