大空間智能主動噴水滅火系統設計原則是怎樣的呢？為了讓大家對其進行更好更多的了解，以便于后期的順利使用，下面
川消小編就來為為您解說下該問題。
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、有些發熱體如燈泡、盛開水的水杯、電爐、煙頭等本身不產生明火，如果紅外探測組件對這類物體無法進行判定，就會導致誤噴。所以要求設計時選用的紅外探測組件不但應具有探測高溫物體的能力，還要具備判定是否為明火的能力。
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、系統設計流量要保證在保護范圍內所有同時開放的噴頭、水炮，在規定持續噴水時間內持續噴水是很難做到的，除非保護范圍的面積不大，設計同時開放的噴頭、水炮數量大于等于保護范圍內可能出現的同時開啟噴頭、水炮的數量。故廣東省規定：系統設計流量應保證在保護范圍內設計同時開放的噴頭、水炮在規定持續噴水時間內持續噴水。
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、大空間智能型主動噴水滅火系統與傳統的自動噴水滅火系統比較，大的區別在于滅火裝置本身具有探測判定火源并主動滅火的能力，不必等環境溫度升高后再開啟噴頭，具有早期發現、早期撲滅火災的能力，可以在火源還是一個點的時候就啟動撲滅火災。
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，理論上其撲滅火災所需要的水量要少的多，持續噴水時間也要短。從消防裝備質量監督檢驗中心及樹上鳥教育給排水設計楊老師對A類火災的滅火實驗結果來看，也證實了這一點。實驗的結果是：一般從火災發生到撲滅只需不到3min的時間。這一條規定之所以目前仍要求系統的持續噴水滅火時間不應低于1小時，是基于以下考慮：
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）系統即使短時間內撲滅了明火（表面火災）后，也應保持一定時間的延續噴水時間以撲滅暗火（深層火災），并繼續減低火場的溫度。
(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）有些火災是在暗火（深層火災）已燃燒擴散到一定程度才轉為可被探測到的明火（表面火災）的，如堆疊式倉庫、高架貨架的底部發生火災時，發現火災的時間一般較遲，火災已蔓延到一定范圍，撲滅火災所需的水量就要增加，撲滅火災所需的時間也較長。
(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）為了與傳統自動噴水滅火系統合用一套供水系統。
(3) In order to share a set of water supply system with the traditional automatic sprinkler system.
(4）暫時缺少對該系統合理持續噴水滅火時間的深入研究及實驗結果。
(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.xintli.net Consult and understand.
