摘　　要：建筑围护结构的严密性对正压送风系统产生着不可忽视的影响 ,而建筑中的各种开口的流量特征也在同时影响了正压送风系统的风量计算。研究这两个因素的确切规律是正压送风系统精确设计的前提。文章就这两个因素的作用规律作初步的论述。The Tightness of the building enclosure has a great impact on the pressurized system,while the flow prope rties of the various openings in the building also affects the air quantity calculation of the pressurized system.The study on the law guiding the two factors is the premise of accurately designing the pressurizde system.The paper discusses the affecting law guiding the two factors.
