Description

A Heptafluoropropane Fire Extinguishing System Applicable to Machine Room

technical field

The utility model relates to the safety field, in particular to a heptafluoropropane fire extinguishing system suitable for machine rooms.

Background technique

Since its inception, the gas fire extinguishing system has been widely used in industrial and civil buildings, and has become the main force to protect computer rooms, communication rooms, generator rooms, power transformation and distribution rooms, precious and precision equipment storage rooms, archives, libraries and other places. Become a powerful weapon for human beings to fight against fire. Before 1996, my country's gas fire extinguishing system was dominated by halon 1211, 1301 and high-pressure carbon dioxide fire extinguishing system. With the formulation of the United Nations "Montreal International Convention" and my country's promulgation and implementation of the "China Fire Protection Industry Halon Overall Elimination Plan" in 1996, in 2010 After 2000, my country will stop producing halon products entirely. In the existing technology, most computer rooms are equipped with carbon dioxide fire extinguishers or do not have fire extinguishers. Excessive use of carbon dioxide fire extinguishers will cause the global greenhouse effect, while computer rooms are places to prevent precision instruments, and built-in instruments often cause fires due to excessive temperature. , so it is necessary to install an efficient, fast, reliable and pollution-free fire extinguishing system.
