The invention discloses an integrated cabin air recirculating system, and belongs to the technical field of aircraft environmental control. The integrated cabin air recirculating system comprises an aircraft cabin, a cabin exhaust valve, a turbine, a heat exchanger, a recirculating fan and a mixing cavity; the mixing cavity is formed in the cold pipeline, and a hot pipeline is connected to a connecting pipeline between the mixing cavity and the aircraft cabin; the aircraft cabin is provided with the cabin exhaust valve, the cabin exhaust valve is connected with the inlet end of the turbine, and the exhaust end of the turbine is connected with a cold side inlet of the heat exchanger; a hot side inlet of the heat exchanger is connected with the aircraft cabin, and a hot side outlet of the heat exchanger is connected with the inlet end of the recirculating fan; the exhaust end of the recirculating fan is connected with the mixing cavity; and the turbine and the recirculating fan are connected through a connecting shaft, and the recirculating fan is driven to pump air of the aircraft cabin for heat exchanging. According to the integrated cabin air recirculating system, cabin exhaust kinetic energy is effectively utilized, the recirculating air temperature is further reduced, that performance penalty loss of an aircraft is greatly reduced by the comprehensive effect, and the economic performance of the aircraft is improved.
Description
technical field [0001] The invention belongs to the technical field of aircraft environment control, and in particular relates to a comprehensive cockpit air recirculation system. Background technique [0002] At present, there are very few domestic researches on aircraft cockpit air recirculation system. The basic principle of foreign aircraft-related recirculation systems is: the fan is driven by the power supply of the aircraft, and the fan sucks part of the air in the cockpit into the mixing chamber and mixes with the cold circuit of the air conditioning component. The final air is finally supplied into the cockpit after being adjusted by the trim system. Although the amount of fresh air supplied to the cockpit is reduced, additional aircraft power consumption is increased. The cockpit exhaust of large and medium-sized civil aircraft abroad is directly discharged into the atmosphere, and the kinetic energy of the exhaust has not been effectively utilized.
