轨道交通地下车站过渡季通风模式研究
Research on ventilation modes in underground stations of rail transit in transition seasons
摘要：
在轨道交通地下车站中，不同地铁运营公司过渡季采用不同的通风模式，导致风机能耗差异较大。以上海某地下车站为例，通过测试过渡季由人行通道渗入站内的新风量和站内CO2浓度，了解了风机不同开启模式下站内的新风量和CO2浓度变化规律，并与站内实时人员需求新风量进行了对比分析，提出了地下车站过渡季风机节能运行建议。
Abstract：
In rail transit underground stations, different underground railway operating companies adopt different ventilation modes in the transition season, resulting in large differences in fan energy consumption. Taking an underground station in Shanghai as an example, by testing the outdoor air volume and CO2 concentration in the station from the pedestrian passage in the transition season, understands the outdoor air volume and CO2 concentration change law in the station under different fan opening modes, compares it with the real-time demand for outdoor air volume in the station, and proposes the suggestions for energy saving operation of fans in underground stations in the transition season.
