The invention relates to an aircraft ground air conditioning unit and a cooling method thereof. The unit can monitor main parameters such as ambient temperature, outlet air temperature, the evaporation pressure and the wind speed of a refrigeration system in real time. When the air conditioning unit is started, compressors are started according to a time interval T1 to quickly reduce the temperature of evaporators, and then the air supply volume is gradually increased according to the evaporation pressure and the operation time, so that the air outlet temperature can be rapidly reduced and thehot air to an engine room can be avoided under the premise of ensuring the safety of the compressors, which effectively improves the cooling efficiency and the comfort of the engine room. Under the condition of ensuring the safe operation of the compressors, the ground air conditioning unit can quickly reduce the outlet air temperature, avoid sending high temperature air to the engine room, so asto improve the cooling efficiency, improve the comfort of the engine room, and extend the service life of the compressors.

    本发明涉及一种飞机地面空调机组及其降温方法,可以实时监测环境温度、出风温度、制冷系统蒸发压力、风速等主要参数,空调机组启动时,根据时间间隔T1启动压缩机,快速降低蒸发器的温度,再根据蒸发压力和运行时间逐步提升送风量,在保证压缩机安全前提下,达到快速降低出风温度、避免往机舱送热风的目的,有效提高降温效率和提高机舱的舒适度。本发明的飞机地面空调机组可以在保证压缩机安全运行的情况下,快速降低出风温度,避免向机舱送高温空气,提高降温效率,提高机舱的舒适度,延长压缩机使用寿命。
