摘要
提出安全疏散判据的标准,定义排烟系统的最佳开启时间。利用FDS对某办公室火灾进行模拟,结合安全疏散判据及各判据超出安全范围的时间,得出该办公室排烟系统最佳开启时间为60 s;设置不同的排烟系统开启时间,得出各判据的变化规律,总结开启时间对安全疏散的影响。及时开启排烟系统,可以有效控制烟气蔓延,开启时间设计应成为排烟系统设计的重要组成部分。
The standards of safety evacuating criterion were given,and the best start time of smoke controlling system was defined.Numerical simulation was carried out on an office fire by FDS combining with the safety criterion and the time of overstepping the safety range.Results showed that the optimum time to start the smoke control system for the office is 60 s.By setting different start times,the variation laws of evacuating criterions were decided,and the influences of start time were summarized.Start the smoke control system in time can promptly control the spread of smoke,and to determine the start time should be an important part of the smoke control system design.
