镂空吊顶对吸气式感烟火灾探测器的影响研究

对现有常见的地铁车站镂空吊顶的类型、镂空率等进行了实际调研，选取设置铝方通镂空吊顶的典型地铁车站，开展夜间停运工况下的初期火灾探测试验，分析研究该车站铝方通镂空吊顶对烟气运动和吸气式感烟火灾探测器安装位置、响应性能的影响。

Influence of Hollowed-out Suspended Ceiling on Aspirating Smoke Fire Detector

Field survey has been carried out for the types of common hollowed-out suspended ceilings, rate of hollow-out, etc. of subway stations. A typical subway station with aluminum square tube hollowed-out suspended ceiling has been selected to conduct initial fire detecting test under shutdown condition at night, and the influences of the aluminum square tube hollowed-out suspended ceiling on smoke movement, the mounting position and response performance of the aspirating smoke fire detector have been analyzed and investigated.
