基于机房灭火需求，从下列几个方面对高压细水雾灭火系统与气体灭火系统进行对比分析，下面
川消小编为您解答。
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、系统灭火效果比较
1. Comparison of system fire extinguishing effect
高压细水雾灭火系统通过高压喷放细水雾实施灭火。灭火剂为水，取材方便低廉；灭火机理是冷却和窒息，灭火效果较好，灭火后不易复燃，在水源保证的情况下，可重复使用。但对于珍贵物品和特别重要的电气设备，使用该系统存在水渍损失风险。
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.
气体灭火系统主要利用灭火剂储瓶释放压力，通过管网和喷嘴喷放灭火气体。七氟丙烷灭火系统主要灭火机理为化学抑制；惰性气体气体灭火系统主要灭火机理为物理窒息。气体灭火的优势在于没有水渍损失风险。但灭火剂只能单次释放，无法复燃问题。
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、对环境影响的比较
2. Comparison of environmental impacts
高压细水雾以水为灭火剂，绿色，对人体和环境没有危害，兼具清洗有毒烟雾和消减烟尘的功能，利于人员的逃生。高压细水雾雾滴水渍损失非常小，对保护对象影响很小。
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.
七氟丙烷系温室效应气体，其全球变暖潜能值GWP100=3350。惰性混合气体(N2、Ar、CO2)或氮气（N2）均来源于空气，对大气环境无不良影响，但对火灾烟尘没有消减作用。
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、对建筑平面布置及相关设备设计的影响比较
3. Comparison of impacts on building layout and related equipment design
高压细水雾灭火系统灭火后不会产生有害气体，仅需在灭火后加强通风；由于耗水量少，可充分利用现有排水系统。
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.
气体灭火系统在灭火后，防护区内会有灭火气体滞留，须打开排烟风机排放。且灭火气体质量密度比空气大，集中于防护区底部，因此，排风口需设置在防护区低位，会影响防护区的使用。另一方面，由于气体灭火组合分配系统对防护区数量和输送距离的限制，如果大型档案库房采用气体灭火将不可避免设置相当多数量（或面积）的钢瓶间，不利于档案库区的布置。
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.cx-fire.com Consult!
