针对某冷库防火分区面积超过规范要求的问题,采用消防性能化设计方法,设置“防火隔离带”进行防火分区划分。运用火灾动力学经验公式进行热辐射计算分析,利用FDS烟气蔓延模拟软件进行火灾模拟分析。计算模拟结果表明,该分区方法,理论上是可行的。并在此基础上提出了建议措施,以进一步保证该冷库的消防安全。
Aiming at the problem that the area of a certain cold storage area exceeds the requirements of the standard, a fire performance-based design method is adopted to set the “fire isolation zone” to divide the fire area. The thermal radiation calculation and analysis are carried out by using the empirical formula of fire dynamics, and the fire simulation analysis by FDS flue gas spreading simulation software is carried out. The simulation results show that the partition method is theoretically feasible. Based on this, suggestions are put forward to further ensure the fire safety of the freezer.
