Conventional Halon 1 fire extinguishing system has a high fire extinguishing capacity, but is an environmental fire extinguishing facility that destroys the ozone layer. Recently, due to the problem of global environmental protection, an environmentally friendly water mist extinguishing system using water is needed in gas extinguishing facilities (Halon, CO₂).

Water mist fire extinguishing equipment is an environmentally friendly fire extinguishing equipment using natural water, so it is waterproof in a fog state, so there is no secondary damage after fire extinguishing.

In particular, the extinguishing water of the present invention is excellent in the extinguishing effect by using the water mist as a extinguishing agent, it can be extinguished in a small amount in the same fire. It uses water which is a natural fire extinguishing agent, so it is cheaper than gas fire extinguishing agent and is excellent for the environment and harmless to human body.

It is easier to recover than existing fire extinguishing facilities using water, and there is no secondary damage. As shown in FIG. 5, the water mist heat absorption effect is the same amount of water, the surface area is increased when the particles are smaller, so the area to absorb heat increases. In addition, the experimental results proved that the water particles released into the water mist are small compared to other water extinguishing systems. For example, dividing water molecules by 100 increases the surface area by 4.64 times, and by 1000 divisions by increasing the surface area by 10 times, increasing the heat absorption area.
