本文介绍了由ASHRAE和加拿大国家研究委员会发起的一个项目的结果，该项目旨在调查由连通空间中的喷火引起的烟雾运动进入相邻的大型开放区域，如中庭或零售商场。作为联合项目的一部分，建立了一个大型试验设施，以调查喷水灭火的烟气流动。本文讨论了两个全尺寸火灾试验系列的结果。在第一系列试验中，丙烷燃烧器系统被用于模拟设计火灾，该火灾具有初始不稳定阶段，然后是具有恒定热释放速率的火灾。最初的火势增长采用了快速的t平方火。这场火灾被允许增长到预定的热释放速率，并随后保持恒定。第二系列完整的- 使用三种火灾场景进行了规模测试，模拟零售商店中发现的典型火灾荷载布置。使用的三种场景如下:纸箱中的纸巾、盒子中储存的衣物和儿童玩具。单元:SICitation:研讨会论文，佐治亚州亚特兰大，2001年

This paper presents results of a project initiated by ASHRAE and the National Research Council of Canada to investigate smoke movement resulting from a sprinklered fire in a communicating space into an adjacent large open area, such as an atrium or retail mall. As part of the joint project, a large-scale test facility was established to investigate smoke flow for sprinklered fires. In this paper, the results of two full-scale fire test series are discussed. In the first series of tests, a propane burner system was used to simulate design fires, which have an initial unsteady stage followed by a fire with a constant heat release rate. A fast t-squared fire was used for the initial fire growth. This fire was allowed to grow to a predetermined heat release rate and subsequently maintained constant. The second series of full-scale tests were conducted using three fire scenarios simulating typical fire load arrangements found in retail stores. The three scenarios used were as follows: paper towels in cartons, clothing stored in boxes, and children's toys.Units: SI
