基于体育馆、影剧院、会堂、礼堂等公共建筑存在人员密集、火灾中疏散距离长等特点,防火要求相对较高,需要对火灾初期做出快速的反应;因此,火灾探测器的灵敏性和准确性显得非常关键。本研究过程在设定建筑尺寸规模的基础上,对各常见类型的火灾探测器动作反应情况运用由美国国家技术标准局开发的FDS软件进行模拟,根据模拟数据得出结论,离子感烟探测器比感温探测器动作灵敏度高,能起到更好的预警作用。
Due to the concentration of public buildings like gymnasiums, theaters, auditoriums and auditoriums, and the long evacuation distance in fires, fire safety requirements are relatively high and a quick response to the initial fire is needed; therefore, the sensitivity and accuracy of fire detectors It is very crucial. Based on the scale of the building, this research process simulates the reaction of all common types of fire detectors using the FDS software developed by the National Bureau of Standards and Technology. According to the simulation data, the conclusion is that the ion smoke detector Sensitivity than the temperature detector high sensitivity, can play a better role in early warning.
