Floor type airplane ground air conditioning unit and control method thereof

Abstract

The invention discloses a floor type airplane ground air conditioning unit and a control method thereof. The floor type airplane ground air conditioning unit comprises a framework structure, an air conditioner air supply system, a refrigerating system, a heating system and an automatic control system, wherein the refrigerating system is a multistage refrigerating system and comprises a first refrigerating system, a second refrigerating system, a third refrigerating system and a fourth refrigerating system; frost is synchronously removed by skillfully arranging the position of a hot air bypass solenoid valve. The floor type airplane ground air conditioning unit has the functions of preventing formation of the frost and automatically removing the frost; each refrigerating system can be put into operation at a highest refrigerating speed; the whole unit can be used for outputting and refrigerating by the highest refrigerating capability after the quick start is completed, thereby ensuring that a cabin of an airplane landing on an airplane boarding bridge can be fastest and best refrigerated in a short time7.

Description

technical field The invention relates to an aircraft ground air-conditioning unit, in particular to a ground-mounted aircraft ground air-conditioning unit and a control method thereof. Background technique At present, there are general aircraft ground air-conditioning units, which are hung and installed under the boarding bridge of the airport, and can move with the bridge. The air is sent into the cabin and cockpit of the aircraft through the air-conditioning air outlet of the aircraft through the heat-insulated delivery hose and quick connector, providing cooled air with a certain flow rate, temperature and pressure after treatment for the aircraft parked at the airport. The use of aircraft ground air conditioning units can reduce the use of aircraft APU, reduce the consumption of expensive aviation fuel, prolong the service life of aircraft air conditioning systems, reduce air pollution, and achieve energy saving and emission reduction. Vigorously developing aircraft gr...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to overcome the backwardness of the control method in the prior art, the slow cooling speed, resulting in a large amount of waste of cooling capacity, poor cooling effect inside the aircraft cabin, easy frosting during operation, short running time, and poor air supply. Due to the technical defects of unstable temperature and flow, a ground-mounted aircraft air-conditioning unit is provided. The operation and defrosting are synchronized, so that the aircraft cabin can achieve the fastest and best cooling effect in a short period of time. The design is reasonable, intelligent, and Compact structure, small size, light weight, good cooling effect, strong support capability, stable and reliable operation
