本研究的主要目的是评估幕式防火阀和多叶片防火/排烟阀在烟雾管理系统中可能出现的环境温度和高温下，以空气速度和关闭压力关闭的能力。其他目标是确定挡板上游和下游的瞬态压力，以及动态关闭后在环境空气和高温下防火/防烟挡板的泄漏。本研究的结果旨在供颁布标准和规范的机构、烟雾管理手册（如ASHRAE（1991a）/设计书/指南/手册）的作者以及烟雾管理系统设计师使用。

The primary purpose of this study was to evaluate the capability of curtain fire dampers and multiblade fire/smoke dampers to close at air velocities and closure pressures at ambient and elevated temperatures that may occur in smoke management systems. Other objectives were to determine the transient pressures upstream and downstream of dampers, and the leakage of fire/smoke dampers at ambient air and elevated temperature after dynamic closure.Results of this study are intended for use by agencies promulgating standards and codes, authors of smoke management handbooks, such as ASHRAE (1991a)/design books/guidelines/manuals, and smoke management system designers.
