As an important place to store historical documents and data, the fire prevention and control is very important. Traditional fire extinguishing methods such as water spray, dry powder, carbon dioxide, etc., although they can effectively extinguish the fire, they may cause secondary damage to precious archives. Therefore, high pressure water mist fire extinguishing system has become the preferred fire extinguishing system for archives because of its high fire extinguishing efficiency and little damage to archives. The following will be a detailed introduction to the application of this fire extinguishing system in archives.
 

1. Working principle of high-pressure water mist fire extinguishing system

 
High pressure water mist fire extinguishing system through high pressure pump water into micron level water mist, using its large surface area to quickly absorb heat and cool down, cut off the fire source oxygen supply, so as to achieve the purpose of fire extinguishing. At the same time, the water content of the mist is less, which has little influence on the wetting of the file.
 

2. Protection of files

 
An important advantage of high-pressure water mist fire extinguishing system is that it has excellent protection performance for files. Due to the small particle size of the water mist, the humidity generated by it is low, which is not easy to cause moisture in the file. Moreover, the response speed of the water mist fire extinguishing system is fast, which can quickly intervene in the early stage of the fire, reduce the possibility of fire spread, and maximize the protection of the integrity of the file.
 

3. Application cases

 
In many well-known archives around the world, including the National Archives in Washington and the British Museum in London, high-pressure water mist fire suppression systems are widely used. These archives have very high requirements for the protection of archives, and the application of high-pressure water mist fire extinguishing system has proved its high efficiency and practicability in archives fire prevention.
 

4. Maintenance and testing

 
Although the high pressure water mist fire extinguishing system performance is excellent, but in order to ensure its normal operation, regular maintenance and testing is necessary. This includes checking that nozzles, high-pressure pumps, water sources, etc., are working properly, and that the system can start up quickly in the event of a fire.
 

Conclusion

 
In general, high pressure water mist fire extinguishing system has become an ideal choice for archives because of its high efficiency and good protection performance. By understanding its working principle and application cases, it is not difficult to see that choosing a suitable fire extinguishing system is of vital significance to protect precious historical documents.
