地铁高架车站变电所通风方案研究

Research on Ventilation Scheme of Substation in Elevated Metro Station

地铁变电所房间具有设备发热量大、布置紧凑等特点,良好的通风降温设计是保证设备正常运行的重要条件。文章以南京某地铁线路为例,针对地铁高架车站变电所房间,提出一种地板风孔送风、机械排风的布置方案。并对其进行工况分析,该方案的气流组织及降温效果较好,同时对车站室外造型的影响也较小,可在实际工程设计中予以借鉴。

The substation room in metro systems has the feature of large calorific, compact layout and good ventilation and cooling design is a key condition to guarantee the equipments in normal work. This paper taked a metro line in Nanjing City as an research object, and proposed a ventilation scheme and mechanical exhaust layout scheme for the substation in elevated metro station, meanwhile analysis its working conditions. The conclusion is that the proposed scheme can achieve prior air distribution, cooling effect, and has small influence to the outer model of the substation, can be reference in practical engineering design.
