In the era of information explosion, the computer room is the main hub for communication transmission, and the reasonable selection of the fire protection system in the computer room is an important guarantee for the safe and stable operation of the equipment in the computer room.
1. Cause of fire in the equipment room
1, data room short circuit: rare, resulting in a low probability of fire;
2, the data room load is too large: the equipment in the room can not meet the needs of users, it is easy to add equipment in the room, but the load of the cable is not easy to transform, which causes the cable load, overheating caused by fire;
3, the old equipment in the data room is not replaced in time: especially the cable is running for a long time with high load, and the cable is not replaced in time, it is easy to melt the insulation layer of the cable at high temperature, and the short circuit causes the fire;
4, the data room dust is large: because the equipment is running for a long time, coupled with the dust is not cleaned up in time, it will cause the high temperature alarm of the equipment, which is easy to cause a fire.
2. Machine room fire hazard
1, threatening life safety: When a fire occurs in the machine room, a large amount of smoke and toxic and harmful gases will be generated, which will threaten the life safety of the fire scene and surrounding personnel;2, the threat of data information security, causing incalculable losses: data centers, network servers, communication hosts and other electronic information equipment storage or transmission of a large number of priceless data information, once a fire, is likely to lead to important data loss, communication interruption, large-scale downtime and other accidents, resulting in immeasurable direct and indirect losses;
2. Wide spread and huge negative impact: communication interruption and server downtime may cause panic in the outside world, resulting in huge negative impact and time-consuming and difficult recovery.
Third, high pressure water mist fire extinguishing system
In view of the fire characteristics of the data room, high pressure water mist system takes a small amount of water as the fire extinguishing medium and adopts a high pressure pump set with a working pressure of no less than 10Mpa to spray water mist with a particle size of less than 100µm at a high speed with a small nozzle specially made around the fire site. In the vaporization process, the water mist is cooled by endoheat and quickly suffocated. In the process of vaporization, the water mist realizes rapid fire extinguishing by rapid endothermic cooling and rapid asphyxiation.Good fire extinguishing effect: rapid cooling in the whole space of fine water mist; The droplet quickly disperses, effectively coping with blocking fire; Continuous spraying, can cope with the reignition fire;
Safety and environmental protection: the fire extinguishing system uses water as the fire extinguishing medium, with green environmental protection, safety, less water, less water pollution, small water mist droplet diameter, there is no need to worry about drainage problems when in use;
Small fire loss: After spraying, the water mist has the function of smoke elimination and poison release, which can reduce the corrosion effect of smoke on cables and equipment;
Application: Because of its wide applicability of fire extinguishing mechanism, it is basically not restricted by the place when used;
Good electrical insulation: can effectively prevent live equipment fire;
Low maintenance: water is used as the fire extinguishing medium, and normal pressure is used in the standby state, and the daily maintenance workload and cost are low.
Fourth, the advantages of the application of water mist in the computer room
1, the high-speed spray of fine water mist can quickly spread to the electrical equipment and surrounding fire, and quickly vaporize, not only overcome the water spray can not effectively extinguish the shortcomings of the fire and deep fire, and eliminate your concerns about a large number of water stains to the operation of electrical equipment to bring safety risks;2, reliable, safe and environmentally friendly water mist system;
3, because the fine water mist has the ability to isolate radiant heat and wash smoke, it can prevent the spread of fire and avoid causing greater losses;
4, with good electrical insulation, can effectively extinguish electrical fires, and does not affect the operation of non-fire equipment;
5, the equipment installation layout is flexible, does not occupy space.
