地铁可调通风型站台门过渡季节自然通风性能测试

摘要

Adjustable platform screen door is a new type of platform screen door and it is distinguished from the traditional one. The air valves installed on the door can be closed in summer to make the air between the platform and the tunnel disconnected and can be opened in transition season to provide ventilation for the station by the use of the piston effect. Yet the performance of this new type of platform screen door is unknown. This paper will introduce the performance of this new platform screendoor by testing the volume of air through the air valves and through the entrances of the station, the concentration of CO2and the temperature of the station. The results indicates that the ventilation caused by the piston effect can meet the needs of thestation in transition season and thus the mechanical ventilation system can be closed to save energy.%可调通风型站台门是一种区别于传统结构的新型的屏蔽门，门上装有可开启和调节角度的风阀，空调季运行时关闭风阀，车站和隧道空气不相通，过渡季节时开启风阀利用活塞风对车站进行自然通风。目前针对该新型屏蔽门实际的通风性能数据缺乏，因此对设置可调通风型站台门的地铁车站在过渡季节的通风性能进行了测试，测试参数包括对通过可调通风型站台门的风量、地铁车站出入口风量以及车站的CO2浓度和温度。测试分析表明，依靠列车活塞效应引起的通风量能够满足过渡季节车站风量的设计要求，因此过渡季节可以关闭车站风机，减少风机能耗。
