Abstract

The invention discloses a rapid cooling type aircraft ground air conditioning unit and a control method of the rapid cooling type aircraft ground air conditioning unit. The highest cooling speed and the largest cold quantity input improve the rapid cooling and cold supplying capacity of the aircraft ground air conditioning unit, processed fresh air with a certain flow, cleanliness, proper temperature and high hydrostatic pressure is provided rapidly for an aircraft, the fresh air is fed to a cabin of the aircraft through a special air feeding hose, the fastest and best cooling effect is achieved for the cabin of the aircraft which stops at an aircraft boarding bridge for a short time, physiological requirements of staff in the cabin of the aircraft are met, high comfort level is achieved, the cooling requirements of precision devices in the cabin are met, a comfortable environment is provided for the staff in the cabin and aircraft operators, the metal state of the aircraft operators is improved, and the safety of driving the aircraft is improved. Meanwhile, fuel consumption produced when the aircraft waits on the ground is reduced, the service life of a self-matched expensive air conditioning system of the aircraft is prolonged, the pollution to air environment of an airport is reduced, and high economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of an aircraft ground air-conditioning unit and a control method thereof, in particular to a ground air-conditioning unit capable of meeting the rapid cooling requirements inside a cabin during a short stay of an aircraft and a start-up and operation method thereof. Background technique [0002] At present, in the existing aircraft ground air conditioning units, the fresh air is directly evaporatively refrigerated or heated by electric heaters in the refrigeration system of the unit, and the cold or hot air is sent into the aircraft through the air-conditioning outlet of the aircraft air conditioner through the insulated delivery hose and quick connector. The cabin and cockpit provide cooling air with a certain flow rate, temperature and pressure for the aircraft parked at the airport. [0003] However, due to the relatively short time for the aircraft to dock on the bridge to board and disembark passengers, the parki...
