摘　　要：同一个防火分区内同时设置自动跟踪定位射流灭火系统与自动喷水灭火系统时,通过分析不同常见场景下纵向障碍物的影响,结合3种型式灭火装置的不同特点,选取不同场景下对应的喷水强度、作用面积等规范数据,并根据实际作用面积进行修正,计算出自动喷水灭火系统的流量,再叠加3种型式自动跟踪定位射流灭火系统的实际流量分别得出一次灭火流量的计算方式。When automatic tracking and positioning jet fire extinguishing system and automatic sprinkler extinguishing system are set in the same fire protection zone,by analyzing the influence of longitudinal obstacles in different common scenes and combining the different characteristics of the three types of fire extinguishing devices,the corresponding specification data such as water spraying intensity and action area are selected in different scenes.The flow of automatic sprinkler system is calculated,and then the actual flow of three types of automatic tracking and positioning jet fire extinguishing system is superimposed to get the calculation method of primary fire extinguishing flow respectively.
