感温火灾探测器的预警时间

Discussion on the Pre-alarm Time of the Heat Detector

文章结合建筑火灾的特性和感温火灾探测器的工作原理 ,分析了感温火灾探测器的换热机理 ,建立其换热数学模型 ,并对此模型作详细的求解计算和实例分析 ,确定了影响感温火灾探测器预警时间的主要因素 。

On the basis of the building fire property and the operational principle of the heat detector, the paper analyses the heat transfer mechanism and sets up its mathematical model of heat transfer which has been calculated and analyzed in great detail. The key factors influencing the pre-time of the heat detector have been determined and the pre-time of it has been given in the paper. The paper can provide reference for the expected time in the whole evacuation process and the safety assessment in the fire protection engineering.
