摘要
针对某体育馆安全区防排烟系统的设计,模拟在相同的火灾场景下采用2 种不同的防排烟系统,即正压送风和机械排烟.通过FDS 软件模拟计算发现,采用机械排烟方式,其在安全区的各项指标(温度、能见度及CO 浓度)均好于采用正压送风方式.该模拟结果对同类建筑安全区的防排烟系统的选择具有一定的借鉴意义.
Abstract
Upon the design of the smoke management system in the safety zone of a gymnasium,two different smoke control modes of the positive pressure air supply and the mechanical exhaust were simulated in the same fire scenarios. The FDS simulation showed all indicators (temperature,visibility and CO concentration)in the safety area were better with mechanical exhaust than with positive pressure air supply. The result had some reference significance for smoke control system selection in the safety zone of similar buildings.
