摘要
地铁车站与连接车站的区间形成一个四通八达的网络,气流流向非常复杂。要想在事故区间形成有效通风,单靠设在车站或风井内的大型隧道风机往往达不到通风效果。此时,若能适时采用诱导射流设备,往往能起到事半功倍的效果。结合地铁通风设计,介绍了射流风机和诱导风机系统这两种常用的诱导射流设备的特点、局限性,以及诱导射流设备的选用,探讨诱导射流设备在地铁中的应用。
Mechanical ventilation systems are generally arranged near stations to ensure appropriate temperature or air velocity in subway system.Since stations and tunnels of subway connect with each other and form a network rediating to all directions,the air flow is very complex.Impulse fan and jet fan,with the capability to produce longitudinal airflows, have an advantage over conventional mechanical system, and therefore a better control of tunnel airflows can be achieved by using impulse fan and jet fan.This paper mainly discusses the application of impulse fan and jet fan in subway system.
