Aircraft ground air conditioning is an important component of replacing aircraft APUs in operating ground equipment, used to provide cabin air conditioning to aircraft instead of aircraft APUs. In view of the poor cooling (heating) effect of aircraft ground air conditioning in extreme weather (extremely cold, extremely hot), through on-site data acquisition and simulation verification of a domestic airline hub, the results show that CFD simulation technology can better simulate the aircraft cabin in the ground air conditioning working mode. Compared with the field test results, the simulation results have a small error and basically conform to the temperature distribution in the cabin.
