The present invention relates to a smoke control system for exhausting smoke due to fire breakout in a house rapidly to the outside in dwelling establishments like an apartment house. The smoke control system of the present invention includes: an inline type smoke control fan which is installed in an exhaust duct installed on a ceiling of an indoor upper part, and exhausts heat and smoke by being operated by electricity applied from the outside in case of fire breakout; a fire damper which is installed in a front end of an exhaustion duct where the smoke control fan is installed, and blocks secondary fire breakout due to absorbed heat; a check valve which is installed at a rear part of the exhaustion duct where the smoke control fan is installed, and blocks inflow of external air into the inside; and a control box which is installed in the smoke control fan, and controls operation of the smoke control fan by receiving electricity or signals of a plurality of lines. The control box is connected to an emergency power line where an emergency electricity is applied in case of fire breakout, a heat sensing line for receiving a signal from a heat sensor, a self-alarm line for receiving a self-alarm signal, a smoke sensor line for receiving a signal from a smoke sensor and a firefighting linked line for receiving a signal linking an operation of a firefighting facility, and operates the smoke control fan by electricity applied from the emergency power line by a signal received from one of the heat sensing line, the self-alarm line, the smoke sensor line or the firefighting linked line. The present invention is for evacuating a refugee by priority by discharging heat and smoke in the inside rapidly in case of fire breakout using the inline type smoke control fan in the exhaust duct installed on the ceiling of the upper part of the inside, and for minimizing loss of life and property due to the fire, and for improving reliability and reducing construction costs by reducing common use space generated by applying ventilation and exhaust. |
