| 摘 要： | 采用一维非稳态流模型，利用连续性方程、运动方程和对流-扩散方程模拟地铁系统内气流速度场、温度场，通过对某工程不同环控方案的空调负荷和温度场进行比较，结果表明车站采用屏蔽门空调能耗降低1／3－1／2，隧道内 空气温度有所上升。通过对车站屏蔽门的分析提出了合理建议。

| Abstract: | Based on one dimensional unsteady flow model, the velocity field of airflow and the temperature field in subway are simulated by use of the continuity equation, the motion equation and the convection diffusion equation. For subway stations with screen doors and those without screen doors, analog computation and comparisons concerning the energy consumption rates of air conditioners and the temperature fields of the wind in tunnels are also made. The station with screen door is analyzed, and some rational suggestions are put forward. |
