| 摘 要： | 利用CFD场模拟软件FDS,对线型红外光束感烟探测器的响应性能进行预测,研究火源类型、火源功率、探测器设置高度、水平安装位置等因素对报警时间的影响.结果表明,相同高度处火灾探测器的响应时间随火源与探测器水平距离的增大而增大;火源功率对探测器的影响随距离增大而减小;火源类型不同,探测器响应数量差异很大.

| Abstract: | Utilizing the CFD field simulating software FDS,to predict the response performance of linear infrared beam smoke detector,and research the influence of alarm time of the fire source type,fire source power,height and horizontal position to the detector.Results showed that,given the same height,the response time of detector increases as the distance between the detector and the fire source increases;the influence of fire source power to the detectors decrease as the distance increase;the number of detectors ... |
