基于数值模拟的住宅简易喷淋灭火系统优化探讨
|
摘要
通过对住宅火灾规律和特点的分析,建立典型住宅模型,采用数值模拟方法,从保障初期安全疏散角度,对住宅设置简易喷淋灭火系统的影响因素进行分析,进行不同流量分配及与报警探测装置联用等工况的对比分析,寻求最佳喷头流量分配的参数工况,从而对住宅简易喷淋灭火系统的优化设置提出建议。
Through analyzing rules and characteristics of residential fire accidents in China, a typical residential model was established by simulation technology. From the perspective of safe evacuation in the early satge of fire, the simulation analysis was made on the effectiveness and impact factors of setting simple residential sprinkler system, and the contrastive analysis on different sprayer flow distributions, as well as its combined application with the alarm detection device, was performed to find out the optimal parameters of sprayer flow distribution. Consequently, suggestions were provided to the optimized setting of simple residential sprinkler system.
