Relying on the fire simulation platform of FDS, the parameter calibration methods for spot-type and air sampling smoke detectors were proposed with considering of their respective working characteristics: time-lag effect and diluting effect.
结果表明:点型探测器对小功率火探测失效;空气采样探测器探测效果受管网布置影响较大,水平管结合下垂管的组合采样方式能有效克服热障环境影响,对各种火灾情况应对能力强,尤其对小功率火探测优势明显。
To study the working performance of contact smoke detectors in large space fire,numerical wind tunnel experiments and ASPIRE2 program were adopted respectively to model the process of smoke entering the sensing chamber of two kinds of detector products:spot-type smoke detector and air sampling smoke detector.
