摘要
阐述了建筑物机械加压送风防烟设施设置部位,讨论了几种特殊情况,对比压差法和风速法送风量计算存在的主要问题,指出风速法开门数量应取4个,建议送风机出口设置压力调节阀,以确保压差值满足规范要求。
This paper summarizes the installing positions of mechanical pressurization air supply smoke proof facility, discusses several special cases, compares major problems in air supply rate calculation by air velocity method and pressure differential method, then points out： it is 4 opening doors that the air velocity method have, pressure control valve should be installed in the outlet of forced draught blower to assure pressure difference meet the requirements of specific codes.
