可调通风型站台门系统在地铁火灾中的适用性

以青岛某地铁车站为研究对象，通过 PyroSim 软件对火灾场景进行数值模拟，设置屏蔽门与通风窗不同的开闭组合方式，着重分析站台内整体和局部测点的温度、CO 质量浓度、能见度等指标。结果表明，相比于单独开启通风窗的工况，同时开启屏蔽门和通风窗的排烟效果较优，单独开启屏蔽门时的排烟效果最差。

Applicability of adjustable ventilationplatform door system in subway fire

Taking a subway station in Qingdao as the research object, carried out numerical simulation of fire scene through PyroSim software, set different opening and closing combination modes of platform screen door and ventilation window, and focused on the analysis of temperature, CO mass concentration and visibility. The results showed that the smoke exhaust effect of opening the ventilation window alone was a little better than that of opening the PSD and ventilation window at the same time, and the smoke exhaust effect was the worst when the PSD opened alone.
