分层空调以其显著的节能性和经济性在高大空间空调设计中被广泛应用。本文简要介绍了新武汉火车站高大候车厅分层空调的设计方案,并应用CFD软件对分层空调夏季设计工况下气流分布特性进行了模拟分析,得到了候车厅的速度场、温度场以及热舒适度分布情况。研究结果表明该设计方案可行,在喷口送风角度为15°时送风效果最好,可以达到设计要求的室内温、湿度与速度分布,并满足室内热舒适性的要求。该分层空调较全室空调可节能约21%。
Stratified air-conditioning with its significant energy-saving and economy in the large space air-conditioning design is widely used. This paper briefly introduces the design scheme of stratified air conditioner in the high waiting hall of new Wuhan railway station. The CFD software is used to simulate the airflow distribution characteristics of stratified air conditioner under summer design conditions. The velocity field, temperature field, Thermal comfort distribution. The results show that the design scheme is feasible and the air supply effect is best when the air supply angle is 15 °. The indoor temperature, humidity and speed distribution can meet the requirements of indoor thermal comfort. The stratified air conditioner can save about 21% of the whole room air conditioner.
