Study On The Automatic Fire Fighting System In Closed Combustible Place

With the fast developments of social economy, city-course and the increase of population, the degree, frequency and losing of fire disaster are in their ascending way in our country and also in all of the world, the fire situation is very austere. For that reason, it is important to find and control the fire disaster, to minimize the losing of people's life and property. The automatic fire fighting system aims at closed combustible place and can automatic alarm and release liquid nitrogen. It adopts a device consisting of smoke-sensor and temperature-sensor as fire-signal collection unit. The system can setup the alarm value for temperature and works with a high automatization degree and dependability. It uses nitrogen as fire extinguishing agent, which is economical, environment-friendly and meets man's needs for environmental protection. It is our new research attempt in this field.
