地铁车站排热风机兼公共区排烟系统方案探讨

Discussion on the scheme of exhaust heat fan and smoke exhaust system in public area of metro station

地铁车站隧道通风系统与大系统服务区域不同,一般分开独立设置,除满足地铁车站正常运营中通风与空调需求外,火灾工况下均具排烟功能。时下,对地铁车站设置排热风机必要性存在一定争议,鉴于此,通过对某地铁车站排热风机和大系统设置情况分析研究,提出了取消大系统排烟风机,由排热风机替代的方案,供大家探讨。

The tunnel ventilation system of subway station is different from the service area of the large system.It is generally installed separately and independently.In addition to meeting the ventilation and air conditioning requirements in the normal operation of the subway station,it also has a smoke exhaust function under fire conditions.Nowadays,there is a certain controversy about the necessity of installing exhaust heat fans in subway stations.In view of this,this article analyzes and studies the installation of exhaust heat fans and large systems in a subway station,and proposes to cancel large system exhaust fans and replace them with exhaust heat fans.Plan for everyone to discuss.
