Optimization design analysis on air conditioning system of a large constant temperature aircraft assembly finishing plant

Taking a large constant temperature aircraft assembly finishing plant as the research object, this paper presents the particularity of the aircraft assembly process and the design scheme of the air conditioning system of the plant. In order to better ensure the accurate control of indoor temperature and reduce the operation energy consumption, the design is optimized from many aspects such as process equipment and air conditioning system schemes. CFD simulation is used to calculate and analyse the speed field and temperature field of the air conditioning system optimization scheme. The results show that the indoor temperature field can meet the design requirements and the requirements of the aircraft assembly finishing environment.
