Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing, and in particular to an intelligent cabinet-type CFA gas fire extinguishing device. Background Art

[0002] Fire extinguishing systems are usually installed in important places such as computer rooms, data processing centers, telecommunication facilities, and museums. The fire extinguishing agents used in gas fire extinguishing equipment on the market are mainly HALON1301, heptafluoropropane, hexafluoropropane, trifluoromethane, etc. Due to the prohibition of production and use of halogenated fire extinguishing agents, seeking a new generation of environmentally friendly and highly efficient gas fire extinguishing technology has become a hot spot in the field of fire research today. As an important HALON alternative technology, inert gas and heptafluoropropane and other fire extinguishing media have dominated the current gas fire extinguishing agent market. However, since heptafluoropropane fire extinguishing media does not contain bromine elements in molecular bonding, its fire extinguishing efficiency is lower than that of HALON1301. In addition, heptafluoropropane media is difficult to decompose in the atmosphere, and the greenhouse effect phenomenon is very serious. It has been recognized as a restricted substance internationally and is only used as a transitional fire extinguishing agent. Subsequently, a more environmentally friendly alternative to halogenated hydrocarbons, "CFA fire extinguishing agent", was successfully developed. Compared with heptafluoropropane, this new fire extinguishing agent has a lower fire extinguishing concentration and a lower greenhouse effect potential. It is liquid at room temperature, easy to transport and store, and has good safety performance. The existing cabinet fire extinguishing device uses CFA fire extinguishing agent. When a fire occurs, it is necessary to manually open the fire extinguisher switch, which reduces the fire extinguishing efficiency and has shortcomings. Summary of the invention
