摘要
分析了目前机械加压送风防烟系统设计的现状,统一了《建规》和《高规》中有关20层以下建筑的最小正压送风量限值,根据不同的风机、风井和风口等设置及控制方式,分别列出了几种不同场所的简易正压送风量电子计算表格,为工程设计提供了设计依据。
Analyzing the current situation of pressure air supply system, unified a minimum pressure air supply quantity about the buildings under 20 floors, according to the Code of design on building fire protection and prevention and the Code for fire protection design of tall buildings, listed several easy Excel sheets about pressure air supply quantity calculating, due to different air fan, air shaft, air outlet installation and control, thus give some advice for the project design.
