旁通阀式余压控制系统的研究

Research on By-pass Damper Type Positive Pressure Control System

详细阐述了旁通阀式余压控制系统的组成、工作原理,并结合实际项目实例,分析了平面优化设计方法。提出旁通阀式余压控制系统是通过设在住宅前室的压力传感器来调节加压送风系统在区域的进风量,从而改变区域的风压差,为疏散通道上防火门的顺利开启提供保障,进而保障人员的安全疏散。

The composition and working principle of the by-pass damper type residual pressure control system were described in detail. Combining by an actural project,the plane optimization design method was anayzed. It is pointed out that the by-pass damper type positive pressure control system is used to adjust the wind pressure of the pressurized air supply system through the pressure sensor of dwelling front room,which changes the wind pressure difference in this area. This system provides the guarantee for the smooth opening of fire doors in the evacuation channel,which ensures the safe evacuation of personnel.
