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.
