The invention relates to a composite air-cooled heat pump aircraft ground air conditioning unit. The composite air-cooled heat pump aircraft ground air conditioning unit comprises a first heat exchanger, a four-way reversing valve, an oil separator, a compressor, an expansion valve, a gas-liquid separator, an electric heater and a second heat exchanger. The outlet end of the compressor is connected with the inlet end of the oil separator. The four-way reversing valve comprises a connector a, a connector b, a connector c and a connector d, wherein the connector a is connected with the outlet end of the oil separator, the connector b is connected with one end of the first heat exchanger, the connector d is connected with one end of the second heat exchanger, the connector c is connected with the inlet end of the gas-liquid separator, and the outlet end of the gas-liquid separator is connected with the inlet end of the compressor. One end of the expansion valve is connected with one end of the first heat exchanger, and the other end of the expansion valve is connected with one end of the second heat exchanger, so that a circulation structure is formed. The invention further discloses a working method of the composite air-cooled heat pump aircraft ground air conditioning unit. The heating efficiency is improved, the problem of insufficient heating is solved, energy conservation and environmental protection are achieved, safety and reliability are achieved, and the problem of increasing shortage and shortage of energy resources is solved advantageously.
