Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aircraft ground air conditioning units, in particular to a composite air-cooled heat pump aircraft ground air conditioning unit and a working method thereof. Background technique [0002] The aircraft ground air-conditioning unit is mainly used when the aircraft is parked on the ground. After the fresh air is directly evaporated and refrigerated by the refrigeration system of the air-conditioning unit or heated by the heating system, the cold or hot air is sent into the aircraft cabin through the air supply pipe to provide air for the aircraft. Quickly provide fresh air with a certain flow, cleanliness, suitable temperature and high static pressure. Due to the technical characteristics of aircraft ground air conditioning units, the outlet temperature of the air conditioner is lower than 2°C when cooling or higher than 30°C when heating. . Since the heating efficiency of the electric heater is less than ...
