消防设计用水量包括流量和水量.建筑中自动灭火系统的设计流量应按其中设计流量最大的一种系统确定,多种消防系统的设计总流量应按其中消防总流量最大的一个防护对象和防护区确定,一个防护区的总流量应为其中的消火栓、自动灭火、水幕系统流量之和.把出现在不同防护区的消火栓系统最大流量、自动灭火系统最大流量和水幕系统最大流量之和作为消防系统的设计总流量不符合每次只有1个失火点的消防基本设定.确定系统的设计水量,方法类似.%Fire prevention system water consumption includes water flow and quantity. The design water flow of the building automatic fire extinguishing system should be determined by the maximum one among all the component water consumptions. The total design water flow of the multiple fire prevention systems should be determined by the maximum one among all the water flow of the protection object or protection area. The total water flow of a protection area should be the sum of hydrant water flow, automatic fire extinguishing system water flow, and water curtain water flow. If the sum of maximum hydrant water flow, maximum automatic fire extinguishing system water flow, and maximum water curtain water flow in different protection areas were taken as the total design water flow of building fire prevention system, it wouldn't fit the basic presumption that there should be only one kindling point once a time. The determination of the fire prevention system water quantity is similar.
