防烟楼梯间及前室正压送风系统区域烟气控制模型的建立

The introduction of the smoke control model of the smoke-preventing staircase

烟控模型是研究防排烟技术的一种重要工具 ,就防烟楼梯间及前室正压送风系统区域烟控模型的算法进行了介绍。该烟控模型分析了包括时间、建筑分隔情况、开口流量系数、围护结构漏风系数、热压风压、风道阻力、开门工况等众多因素对正压送风系统的影响 ,并以网络数值计算为工具 ,对正压送风系统进行了动态分析。模型的建立对于建筑特别是大型公共建筑的消防安全进行性能化评估具有重要的意义。

The smoke control model is a important tool to have a smoke control research.This article introduces a smoke contuol model of the smoke preventing staircase in high rise buildings.The model analyses many factors that will affect the operation of the pressurizing system in the smoke preventing staircases,such as the time,the compartmentaion condition and the door opening condition.
