大空间智能主动喷水灭火系统设计原则是怎样的呢？为了让大家对其进行更好更多的了解，以便于后期的顺利使用，下面
川消小编就来为为您解说下该问题。
What is the design principle of large space intelligent active sprinkler system? In order to let you have a better and more understanding of it, so as to facilitate its smooth use in the later stage, the following Sichuan Xiaobian will explain this problem for you.
1、有些发热体如灯泡、盛开水的水杯、电炉、烟头等本身不产生明火，如果红外探测组件对这类物体无法进行判定，就会导致误喷。所以要求设计时选用的红外探测组件不但应具有探测高温物体的能力，还要具备判定是否为明火的能力。
1. Some heating elements, such as light bulbs, water cups filled with water, electric stoves, cigarette butts, etc., do not generate open flames themselves. If the infrared detection module can not judge such objects, it will lead to erroneous spraying. Therefore, the infrared detection components selected in the design should not only have the ability to detect high-temperature objects, but also have the ability to determine whether it is an open fire.
2、系统设计流量要保证在保护范围内所有同时开放的喷头、水炮，在规定持续喷水时间内持续喷水是很难做到的，除非保护范围的面积不大，设计同时开放的喷头、水炮数量大于等于保护范围内可能出现的同时开启喷头、水炮的数量。故广东省规定：系统设计流量应保证在保护范围内设计同时开放的喷头、水炮在规定持续喷水时间内持续喷水。
2. The design flow of the system shall ensure that all nozzles and water cannons opened at the same time within the protection range. It is difficult to spray water continuously within the specified continuous spraying time, unless the area of the protection range is not large, and the number of nozzles and water cannons opened at the same time is designed to be greater than or equal to the number of nozzles and water cannons that can be opened at the same time within the protection range. Therefore, the landmark of Guangdong Province stipulates that the design flow of the system shall ensure that the sprinkler and water monitor designed to be open at the same time within the protection range can spray water continuously within the specified continuous spraying time.
3、大空间智能型主动喷水灭火系统与传统的自动喷水灭火系统比较，大的区别在于灭火装置本身具有探测判定火源并主动灭火的能力，不必等环境温度升高后再开启喷头，具有早期发现、早期扑灭火灾的能力，可以在火源还是一个点的时候就启动扑灭火灾。
3. Compared with the traditional automatic sprinkler system, the big difference between the large space intelligent active sprinkler system and the traditional automatic sprinkler system is that the fire extinguishing device itself has the ability to detect and determine the fire source and actively extinguish the fire. It does not have to wait for the ambient temperature to rise before starting the nozzle. It has the ability to detect and extinguish the fire at an early stage. It can start to extinguish the fire when the fire source is still a point.
所以，理论上其扑灭火灾所需要的水量要少的多，持续喷水时间也要短。从消防装备质量监督检验中心及树上鸟教育给排水设计杨老师对A类火灾的灭火实验结果来看，也证实了这一点。实验的结果是：一般从火灾发生到扑灭只需不到3min的时间。这一条规定之所以目前仍要求系统的持续喷水灭火时间不应低于1小时，是基于以下考虑：
Therefore, theoretically, the amount of water needed to extinguish the fire is much less, and the continuous spraying time is also short. This is also confirmed by the fire extinguishing experiment results of class a fire conducted by the national fire equipment quality supervision and inspection center and teacher Yang from the tree bird education water supply and drainage design center. The result of the experiment is that it generally takes less than 3min from the fire to the fire. The reason why this provision still requires that the continuous sprinkler time of the system should not be less than 1 hour is based on the following considerations:
(1）系统即使短时间内扑灭了明火（表面火灾）后，也应保持一定时间的延续喷水时间以扑灭暗火（深层火灾），并继续减低火场的温度。
(1) Even after the system extinguishes the open fire (surface fire) in a short time, it should maintain a certain continuous water spraying time to extinguish the dark fire (deep fire) and continue to reduce the temperature of the fire site.
(2）有些火灾是在暗火（深层火灾）已燃烧扩散到一定程度才转为可被探测到的明火（表面火灾）的，如堆叠式仓库、高架货架的底部发生火灾时，发现火灾的时间一般较迟，火灾已蔓延到一定范围，扑灭火灾所需的水量就要增加，扑灭火灾所需的时间也较长。
(2) Some fires turn into detectable open fire (surface fire) after the dark fire (deep fire) has been burned and spread to a certain extent. For example, when a fire occurs at the bottom of a stacked warehouse or elevated shelf, the time to discover the fire is generally late. If the fire has spread to a certain range, the water required to extinguish the fire will increase, and the time required to extinguish the fire will also be longer.
(3）为了与传统自动喷水灭火系统合用一套供水系统。
(3) In order to share a set of water supply system with the traditional automatic sprinkler system.
(4）暂时缺少对该系统合理持续喷水灭火时间的深入研究及实验结果。
(4) There is a lack of in-depth research and experimental results on the reasonable continuous sprinkler time of the system.
When arranging sprinklers and water cannons, you should avoid the water droplets and water columns from being blocked by obstacles in the process of reaching the fire source. For more precautions, please visit our website http://www.cx-fire.com Consult and understand.
