摘要
结合某市地铁3号线的环控系统运行情况,分别对各地铁站的环控风机在火灾工况下运行频率、风量、风压和能耗进行了现场实测,并利用计算流体动力学和风机流动特性理论,建立了在火灾工况下的CFD风机流场模拟模型,对流场进行了计算机模拟分析,为地铁环控系统故障诊断及运行管理提供了重要依据。
Combined with the environment control system of metro line 3 in a city,the operating frequency,air volume,wind pressure and energy consumption of the environment control fan in the subway stations were tested under fire conditions. The simulation model of the fan＇s flow field under the fire conditions was established by using CFD and the theory of fan＇s flow characteristics. The flow field was simulated and analyzed by the computer. It provides an important basis for the fault diagnosis and operation management of the subway environment control system.
