| 摘 要： | 通过现场实验研究，讨论风机设置于建筑上部的多点加压送风系统的设计，通过数值拟合的方法得出送风管道中的风速分布，风速与加压风机的流量、送风管道的截面积以厦管道的高度有关。在实际情况下，研究影响高层建筑加压送风系统的各种因素有着较为重要的意义。

| Abstract: | By field tests of pressurization air supply systems of stairwell,antechamber and common antechamber for a tall building in Hefei, then we do some mathematic analysis for this, and give a calculate method of critical velocity which can prevent the smoke. A design for pressurization system in a multiple injection system with upper injection is discussed and the velocity in duct is found by approach method. This velocity has a relation with volume flux from pressurization fan, section area of pressurization duct and height of duct. In factual situation, there is an important assistant meaning on researching the design of pressurization air supply system in tall buildings. |
