1) detection of abandoned pit
采空探测
4) air sampling smoke detector
空气采样探测器
1.
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。
