暖通空调管道中烟雾传播的特性被描述为开发性能指标以评估管道安装烟雾探测器响应的更大努力的一部分。这种测量应适用于一系列探测器，并考虑热释放率、燃料成分和高气流造成的稀释。本文介绍了从小规模实验中收集的数据，为此类性能指标提供了见解。管道中的烟雾具有多种特征，包括激光片、白光遮蔽、速度分布和温度分布。 记录带有单个取样探头的探测器的响应。烟雾特性可以通过火的大小和气流速度来衡量，尽管它强烈依赖于燃料和燃烧特性。光密度和质量光密度被确定为表征烟雾和烟雾探测器响应的有用指标。单元:干燥:研讨会论文，大西洋城，2002年

The characteristics of smoke traveling in an HVAC duct are described as a part of a larger effort to develop performance metrics to assess the response of duct-mounted smoke detectors. Such a measure should apply to a range of detectors and account for heat release rate, fuel composition, and dilution due to high airflows. In this paper, data collected from small-scale experiments are presented that provide insight to such a performance metric. The smoke in a duct is characterized by several means, including a laser light sheet, obscuration of white light, velocity profile, and temperature distribution. The response of a detector with a single sampling probe is recorded. Smoke characteristics could be scaled by the fire size and airflow rate, though with a strong dependency on the fuel and burning characteristics. The optical density and mass optical density are determined to be useful metrics for characterizing smoke and smoke detector response.Units: SI
