点型火灾报警探测器保护范围对布置的影响

分析了点型火灾报警探测器＂保护半径＂与＂保护面积＂的内在关系,得出了以保护半径为主,保护面积及修正系数为辅新型计算方法,使其在不规则平面更有可操作性,能充分发挥探测器效能,给设置留下了宽裕的选择范围,使设置更趋合理;在安全性不受影响下,探测器用量最大可节省12%。

The Analysis of the Impact of "Protected radius" on the "Protected area"

Based on the analysis of the relationship between the protected area and protected radius,this paper suggests a computation method focusing on the protected radius with reference to the protected area and correction coefficient.The method is more operational in the irregular plane,and it can give full play to the detector performance,allowing for the range of options,offering more reasonable set.While security will not be affected,the detector can save the largest amount by 12%.
