摘要
中庭式大空间建筑功能和结构复杂 ,一旦发生火灾 ,易造成巨大损失。通过对中庭式大空间建筑的特点及其发生火灾时烟气流动特性的分析 ,对对应于火灾现象的火灾探测器进行了分类 ,并综合比较几种常用火灾探测器的探测性能、适用场合及产生误报警的原因 ,提出了一种充分考虑探测器性能、建筑空间形状、火灾特点及可能发生的危险 ,能合理应用于中庭的火灾探测器选用方法 ,用一个实例说明了该方法对于准确、及时地探测火灾并报警、从而减少损失是有效的。
The fuction and structure of the atrium are very complexity. If fire occurs,it will bring great loss. Forms of atrium and the characters of gas flow are analyzed, fire detectors are classified. Performance, applicability and the cause of wrong alarm of fire detector are compared comprehensively. According to the performance of detector, the shape of atrium and the character and possible danger of fire,a method of selecting fire detector to be applied to atrium is given. The validity of the method is explained clearly with an given example.
