Carbon dioxide is the earliest extinguishing agent used in gas fires. In the fire extinguishing solution of the power distribution room, carbon dioxide is widely welcomed by customers because of its one-time investment and low maintenance cost of Nissan. However, from the perspective of instrument protection and personnel safety, there are some deficiencies in the carbon dioxide fire extinguishing system. “ 冷激 ” 、 “ 冷淬 ” 现象，对精密仪器有一定程度的损坏。 On the one hand, carbon dioxide stored in liquid or solid state vaporizes and absorbs heat during injection, which causes the temperature of the protected area to drop rapidly for a short period of time, causing " cold shock " and " cold quenching " phenomena and damage to precision instruments to a certain extent. On the other hand, to achieve the fire extinguishing effect, the fire extinguishing concentration of carbon dioxide is greater than the asphyxiating concentration of people, which is not suitable for places where people often stay.
