摘要
本文分析了对高层建筑防烟楼梯间及其前室、消防电梯前室或二者合用前室进行机械加压送风的必要性，并在大量实际工程调研和资料分析的基础上，对不同的系统负担层数和送风部位给出了加压送风量；通过对不同计算公式的比较和对主要影响因素的分析，提出了加压送风量计算公式的选择，公式参数的确定及其他设计考虑要点。
This paper explains the importance to highrise building fire safety of fitting the pressurization system to supply fresh air into the staircases,fire elevator shafts and the antechambers of the both in case of fire.The authors present a list of values of supply air volume for the floor number supplied by each system and different sections the air is delivered to and recommand selection of the calculating formulas,determination of the factors in the formulas and other few points to be considered in design.
