高层建筑加压送风系统试验研究

Test of pressurization air supply systems for a tall building

介绍了哈尔滨市一座高层建筑楼梯间及其前室、合用前室的加压送风系统的试验情况。分析了几种不同试验工况下 ,楼梯间与前室、合用前室的正压值、门洞风速、加压送风量等问题 ,并对机械加压送风的若干问题作了探讨。试验结果表明 ,目前国内在加压送风系统设计、验收、防排烟产品质量方面存在不少问题 ,必须认真对待。《高规》中有关加压送风的某些条文有待进一步充实和完善。

Presents field tests of pressurization air supply systems of stairwell, antechamber and common antechamber for a tall building in Harbin. Analyses positive pressure values, critical air velocity and supply air rate of stairwell, antechamber and common antechamber under various test conditions and discusses some problems in mechanical pressurization air supply systems. The tests bring to light problems in design and acceptance of pressurization air supply systems and smoke control product quality and those need to be seriously treated. The results also indicate that the Code for fire protection design of tall buildings needs to be revised and made perfect.
