基于機房滅火需求，從下列幾個方面對高壓細水霧滅火系統與氣體滅火系統進行對比分析，下面
川消小編為您解答。
Based on the fire fighting demand of the machine room, the high-pressure water mist fire extinguishing system and the gas fire extinguishing system are compared and analyzed from the following aspects. The following is the answer for you.
1、系統滅火效果比較
1. Comparison of system fire extinguishing effect
高壓細水霧滅火系統通過高壓噴放細水霧實施滅火。滅火劑為水，取材方便低廉；滅火機理是冷卻和窒息，滅火效果較好，滅火后不易復燃，在水源保證的情況下，可重復使用。但對于珍貴物品和特別重要的電氣設備，使用該系統存在水漬損失風險。
The high-pressure water mist fire extinguishing system uses high-pressure water mist to extinguish the fire. The fire extinguishing agent is water, and the materials are convenient and cheap; The fire extinguishing mechanism is cooling and suffocation. The fire extinguishing effect is good, and it is not easy to re ignite after fire extinguishing. It can be reused under the condition that the water source is guaranteed. However, for precious items and especially important electrical equipment, there is a risk of water damage when using this system.
氣體滅火系統主要利用滅火劑儲瓶釋放壓力，通過管網和噴嘴噴放滅火氣體。七氟丙烷滅火系統主要滅火機理為化學抑制；惰性氣體氣體滅火系統主要滅火機理為物理窒息。氣體滅火的優勢在于沒有水漬損失風險。但滅火劑只能單次釋放，無法復燃問題。
The gas fire extinguishing system mainly uses the fire extinguishing agent storage bottle to release pressure, and sprays fire extinguishing gas through the pipe network and nozzle. The main extinguishing mechanism of heptafluoropropane fire extinguishing system is chemical inhibition; The main extinguishing mechanism of inert gas fire extinguishing system is physical asphyxiation. The advantage of gas extinguishing is that there is no risk of water damage. However, the fire extinguishing agent can only be released once, which cannot solve the problem of re ignition.
2、對環境影響的比較
2. Comparison of environmental impacts
高壓細水霧以水為滅火劑，綠色，對人體和環境沒有危害，兼具清洗有毒煙霧和消減煙塵的功能，利于人員的逃生。高壓細水霧霧滴水漬損失非常小，對保護對象影響很小。
High pressure water mist uses water as the fire extinguishing agent, which is green and environmentally friendly, has no harm to human body and the environment, and has the functions of cleaning toxic smoke and reducing smoke and dust, which is conducive to the escape of personnel. High pressure water mist drops have very little water stain loss and little impact on the protected objects.
七氟丙烷系溫室效應氣體，其全球變暖潛能值GWP100=3350。惰性混合氣體(N2、Ar、CO2)或氮氣（N2）均來源于空氣，對大氣環境無不良影響，但對火災煙塵沒有消減作用。
Heptafluoropropane is a greenhouse gas, and its global warming potential value GWP100=3350. Inert mixed gas (N2, Ar, CO2) or nitrogen (N2) all come from the air and have no adverse effect on the atmospheric environment, but have no reduction effect on fire smoke.
3、對建筑平面布置及相關設備設計的影響比較
3. Comparison of impacts on building layout and related equipment design
高壓細水霧滅火系統滅火后不會產生有害氣體，僅需在滅火后加強通風；由于耗水量少，可充分利用現有排水系統。
The high-pressure water mist fire extinguishing system will not produce harmful gas after extinguishing, and only need to strengthen ventilation after extinguishing; Due to low water consumption, the existing drainage system can be fully utilized.
氣體滅火系統在滅火后，防護區內會有滅火氣體滯留，須打開排煙風機排放。且滅火氣體質量密度比空氣大，集中于防護區底部，因此，排風口需設置在防護區低位，會影響防護區的使用。另一方面，由于氣體滅火組合分配系統對防護區數量和輸送距離的限制，如果大型檔案庫房采用氣體滅火將不可避免設置相當多數量（或面積）的鋼瓶間，不利于檔案庫區的布置。
After the gas fire extinguishing system extinguishes the fire, there will be fire extinguishing gas trapped in the protection area, so the smoke exhaust fan must be opened to discharge. In addition, the mass density of fire extinguishing gas is higher than that of air, and it is concentrated at the bottom of the protection area. Therefore, the air outlet should be set at the low position of the protection area, which will affect the use of the protection area. On the other hand, due to the limitation of the combined distribution system of gas fire extinguishing on the number of protection areas and transmission distance, if gas fire extinguishing is used in large archives warehouse, a considerable number (or area) of cylinder rooms will inevitably be set up, which is not conducive to the layout of archives warehouse area.
Therefore, for the machine room, the use of high-pressure water mist fire extinguishing system is more economical, especially the late maintenance cost advantage is obvious. More relevant content will come to our website http://www.xintli.net Consult!
