摘　　要：针对楼梯间加压送风系统的风量调节与泄压(统称“补偿”)问题,简要回顾了自1999年以来共6个版本的《ASHRAE手册——HVAC应用分册》中烟气控制篇章的修订更新,以及在此问题上基于相关研究进展而产生的理论创新与技术内容调整。结合国内实际,分析了实施GB 51251—2017《建筑防烟排烟系统技术标准》有关规定过程中的几个问题并提出了改进建议。Aiming at the issue of air volume regulation and pressure relief(collectively referred to as‘compensation’)for pressurized air supply systems in stairwells,this paper briefly reviews the revisions and updates of the smoke control section in six editions of ASHRAE handbook—HVAC applications since 1999,as well as the theoretical innovations and technical content adjustments based on the progress of relevant research on this issue.Combined with the domestic reality,several problems in the process of implementing the relevant provisions of GB 51251-2017 Technical standard for smoke management systems in buildings are analysed and suggestions for improvement are put forward.
