RESEARCH ON AIR DISTRIBUTION IN AIR-CONDITIONED RAILWAY STATION

摘要：

This study intends to evaluate and optimize the thermal environment inside an air-conditioned railway station using computational fluid dynamics (CFD). The impacts of some air conditioning design parameters such as the supply air temperature, velocity, altitude and angle on indoor thermal environment are also discussed. After discussion, the primary air conditioning design scheme is optimized. The numerical results demonstrate that supply air temperature, velocity, altitude and angle have great effects on the thermal environment in the railway station; the supply air altitude had better be the middle height of the building for the stratified air conditioning in order to obtain satisfactory thermal environment in the railway station; analysis to the effect of design parameters on the indoor thermal environment provides a scientific way for the optimization of design scheme.
