摘要
针对高层建筑防烟楼梯间及其前室机械加压送风量的计算,对压差法、门洞风速法及查表法进行介绍。以某高层住宅建筑为例,分别采用计算法、查表法确定楼梯间、合用前室的送风量,进行对比研究建议疏散门采用标准单开门时加压送风量通过查表法确定,疏散门为双开门时加压送风量采用计算法确定。
Based on the calculation of mechanical pressurized air supply volume for smoke proof staircase and its antechamber of high-rise building,the pressure difference method,the doorway wind speed method and the table look-up method were introduced.Taking a high-rise residential building as an example,the air supply volume of stairwell and shared antechamber was obtained by calculation method and table look-up method respectively,and the results were researched comparatively.It was suggested that the pressurized air supply volume should be directly determined by table look-up method when the evacuation door adopts the standard single door,and the pressurized air volume should be determined by calculation method when the evacuation door is double door.
