某超市防排烟系统设计及安全性能评估

Design of the smoke exhaust system & Fire safety evaluation on a Supermarket

针对某两层超市建筑特点及根据相关规范要求,把超市划分成7个防火分区,每个防火分区又划分为若干防烟分区,并设计排烟系统,以便及时排除火灾产生的有毒烟气。设计结束后利用性能化防火设计方法对该超市在设定火灾条件下烟气充填以及人员疏散情况进行研究,判断设计的合理性。研究结果表明:在设定火灾条件下,该超市能够保证人员安全疏散时间。

Based on the characteristic of the architecture and national criterions, the supermarket was divided into seven fire compartments and every fire compartment was compartmentalized into several smoke bays. Smoke exhaust system was designed in order to exhaust the deleterious smoke in time. Its fire safety was evaluated with performance-based method in this paper and under a settled fire case, smoke movement and people, evacuation was investigated. The result proved that people could evacuate before the fire hazard occurred.
