摘　　要：从风量、风管和风口的设计、防烟部位正压控制方式等角度,分析了加压送风系统设计中需要注意的几点问题:风量的确定需合理有据;楼梯间风管和风口的设计需考虑均匀送风要求,前室风口设计确保不同楼层前室风口开启时风机运行工况稳定;每个防烟部位独立设置加压送风支管和电动旁通泄压阀门,可实现防烟部位正压独立控制。Several problems in the design of positive pressure air supply system are analyzed from the angle of the air supply,the design of the air supply pipe and the air supply outlet and the control mode of the positive pressure control of the smoke prevention parts.When designing staircase air supply pipe and the air supply outlet,the demand for uniform air supply needs to be considered.When the front chamber air supply outlet is designed,the stable operating condition of the fan needs to be ensured when the front vents of different floors are opened.Each smoke control part is independently provided with a pressurized air supply branch and an electric bypass pressure relief valve,so that the positive pressure independent control of smoke prevention parts can be realized.
