Abstract: The unreasonable use of air conditioning load bridge has resulted in the inability to achieve energy saving and emission reduction and meet the requirements of cabin comfort control, aircraft cabin energy consumption model is constructed to predict the thermal load of aircraft cabin and achieve optimal control of bridge load air conditioning. Taking A320 aircraft cabin of TBIA as research object, various factors affecting cabin energy consumption is analyzed using heat balance method. Meanwhile, the meteorological parameter model, cabin envelope heat balance model and cabin air heat balance model are constructed. Heat transfer process is simulated and calculated, and the energy consumption of aircraft cabin at different time is obtained. Results provide a theoretical basis for future study of heat transfer comfort control of aircraft cabin and the energy saving control of aircraft air conditioning system.

Key words: aircraft cabin, energy consumption model, heat balance method, energy consumption prediction
