摘要
介绍某商业综合体防火分区设置,针对其室内步行街防火分区划分存在的问题,设置步行街临街商铺火灾和中庭火灾,改变自动喷水灭火系统、机械排烟系统、火源功率三个因素设置6个火灾场景,分析火灾后烟气流动。设置两个场景模拟人员疏散,比较可用疏散时间和必要疏散时间,分析其防火分区划分的可行性。
The arrangement of a commercial complex was discussed in this study. Aiming at issues of the fire compartment of large indoor pedestrian street, smoke flow after the fire of shops along pedestrian street and courtyard was analyzed in six fire scenarios by changing automatic sprinkler system, mechanical smoke extraction system and fire power. Available safety egress time and necessary evacuation time were compared to assess the feasibility of fire compartment arrangement by setting two evacuation scenarios.
