| 摘 要： | 通过对地铁车站公共区的热负荷进行分析计算,确定了远期地铁车站公共区逐时通风量,结合天津市地铁1号线环控系统的设计方案,提出了空调风机全年变频运行,并用计算流体力学(CFD)模拟的方法,借助Airpak软件,模拟夏季车站变风量运行时车站公共区的温度场和速度场,得出变风量运行后能够达到的设计要求。

| Abstract: | Based on the calculated cooling load of common area in the subway station,the hourly ventilation rate could be determined.Combined with the design plan of 1# line of Tianjin Subway,the year-round frequency control strategy for the fan was put forward.In addition,using the CFD technology and Airpak software,the velocity and temperature fields under the VAV-based operation mode in the common area in summer were simulated.Finally,it was found out that the related results could satisfy the design requests. |
