摘要
通过对加压送风系统开关门状态等引起风量差异原因的分析,说明对消防前室加压和10层以下的楼梯间加压系统设置余压控制措施是必要的。提出对目前设计手册中泄压阀选用计算公式的修正。已完成的工程实例参考了香港地区加压系统余压控制的做法。结论是使用压差探测开关+电动旁通阀应用于消防前室加压系统及使用泄压阀应用于10层以下的楼梯间加压系统是有效的,也更经济。
By means of analyzing the imparity of airflow between door opening and closing mode, it is necessary to control the positive pressure of antechambers and smoke-proof staircases （less than 10 floors）. Modifying the formula of calculation the dimension of pressure relief damper in the handbook. Using some practical experience from Hong Kong in one project. Present the conclusion that it is effective and economical to use differential pressure detector and by-pass damper to control the positive pressure of an antechambers pressurization supply system, to use pressure relief damper to control the positive pressure of a smoke-proof staircases pressurization supply system.
