摘　　要：为了改善西安火车站候车厅内的热环境,利用CFD模拟软件Airpak对两种不同气流组织方案下(上送上回,上送下回)候车厅内速度场、温度场、热舒适性指标PMV及PPD的分布进行数值模拟,通过对比分析,验证不同方案下气流组织形式的特点。结果表明采用上送上回风形式下气流组织的均匀性更好,为今后西安火车站改扩建在空调系统优化设计以及气流组织预测等方面提供借鉴和指导。In order to improve the Xi＇an railway station waiting room within the demands of thermal comfort,CFD simulation software-Airpak were used to numerically simulate the two different air distributions scheme（up-inlet and up-outlet,up-inlet and down-outlet）,with waiting room of velocity field,temperature field,thermal comfort index PMV and PPD.Through comparison and analysis,verify the feasibility of the optimization scheme of air distribution organization was verified.The results show that the up-inlet and down-outlet on the uniformity of air distribution organization is better.Results in the paper provide reference and guide for the future reconstruction of Xi＇an railway station in air conditioning system optimization design and air distribution forecasting.
