提供可用于中庭烟雾管理系统设计分析的信息。讨论管理中庭烟雾的各种方法。指出中庭天花板下方通常会形成一层热空气，这会阻止一些热空气到达天花板。讨论了在这种情况下处理烟雾探测的方法。需要进行调试，以确保烟雾控制系统在火灾期间按预期运行。认为调试工作应在设计之前开始，并延长至施工完成后的维护系统修改。 得出的结论是，需要研究1）中庭和连通空间之间使用气流进行烟雾控制，以及2）防止中庭排气从下层吸入空气所需的烟雾层深度。单位:双关键词:1997年，中庭，烟雾，气流，计算，设计，烟雾通风:研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997

Presents information that can be used for design analysis of atrium smoke management systems. Discusses various approaches to managing smoke in atria. Points out that often a layer of hot air forms beneath an atrium ceiling and can prevent some reaching the ceiling. Discusses a method for dealing with smoke detection in this situation. States commissioning is needed to ensure that smoke control systems will function as intended during a fire. Argues commissioning efforts should start before design and extend until maintenance system modifications after construction are finished. Concludes that research is needed concerning 1) the use of airflow for smoke control between the atrium and communicating spaces and 2) the depth of smoke layer required to prevent atrium exhaust from pulling air from the lower layer.Units: DualKEYWORDS: year 1997, Atria, smoke, air flow, calculating, designing, smoke ventilation
