Solar Heat Migration and Spatial Mode Optimisation of Airport Terminals on the Qinghai-Tibet Plateau Under Unbalanced Heating
摘要
Abstract
The characteristics of unbalanced heating of airport terminals on the Qinghai-Tibet Plateau are very significant,and unbalanced heating is manifested as the differentiated spatial temporal distribution of direct solar radiation.That is,heat is excessive in the upper part,in the south-facing direction,and during the day,while it is insufficient in the lower part,in the north-facing direction,and during the night.The heat load of zones and periods with poor heating is the root cause of the significant energy consumption of airport terminals in this area.Therefore,how to achieve peak cutting and valley filling through heat migration from upwards to downwards,south to north,and day to night is an effective way to address the energy conservation challenges of airport terminals on the Qinghai-Tibet Plateau under unbalanced heating.This paper follows the logic of"space module development-space mode optimisation-space mode application".Firstly,the building space was taken as the carrier and the heat migration was taken as the guide;space modules of"heat collection,heat storage,heat supply,and heat preservation"were established by combining building space and heat migration.Secondly,based on the building prototype of airport terminals,the above space modules were integrated to optimise the spatial mode of the local airport terminals.Finally,the software ANSYS Fluent was used to simulate and compare the heat distribution before and after the optimisation of the spatial mode,and the effectiveness of spatial mode optimisation was verified.The aim is to improve the indoor thermal environment without mechanical equipment by addressing the problem of unbalanced heating and achieving energy conservation and carbon reduction in the operation of airport terminals on the Qinghai-Tibet Plateau.关键词
