Quickly absorb the heat suppression condition of a fire, and people is not injured, other such as dry powder, foam, noble gas
The most inapplicable at crowded place Deng fire-fighting mode.First of the whole nation that public security fire-fighting army unit of Sichuan Province develops is prevented
Fire type bus, installs sprinkling extinguishing device additional, and sprinkling extinguishing device uses air compressor to produce pressure and passes through
Special spray head ejection water droplets, but have the disadvantage in that
1. plant running needs vehicle-mounted power supply to provide bigger power to maintain, and once fire causes supply line to be broken
Electricity just cannot work on；
2. air compressor starts needs certain time to can be only achieved rated pressure, about about 10 seconds, wrong
Cross and most preferably put out a fire opportunity；
3. cost is the highest, it is impossible to popularization and application.
