Auto smoke removed system for smoke removed zone of building

摘要

The present invention provides automatic ventilation relates to a system, its purpose is fire the study prevented definitely from being a regional smoke from entering the while smoke control areas and this constant value over the differential pressure generated between the outside of the ventilation zones for smoke control areas of the building by preventing the rising elderly also easy to open the door of the ventilation zone is to provide an automatic ventilation system for smoke control areas of buildings that can be quickly and safely evacuated to allow access into and out of the ventilation zones, the configuration of each of the ventilation is installed at a predetermined position of the air line that is the first study to supply air to a region connected to be the communication with the study regional pressure blower and each of the ventilation intended to increase the area to the air flow line being connected in communication with the zone, It is respectively attached to a plurality of end portions of the ventilation line is generated between the outside of the ventilation zone and the ventilation zone Is in the conventional automatic ventilation system comprising a differential pressure regulating damper to control the differential pressure, the system comprising: a bypass pipe is connected in communication with a predetermined position of the air blowing line for bypassing the air from flowing into the ventilation line to the outside, and; Has its own sensor for sensing the pressure in said air line, a control means and is electrically connected to and mounted on the bypass pipe, the example value or more when the bypass pipe pressure in conjunction with the differential pressure regulating damper, or air flow line the opening and characterized in that it comprises an overpressure automatic discharging device, which by-pass the blowing air in the air flow line to the outside.
