Title:
METHOD AND SYSTEM FOR PRESSURIZING, SUPPLYING AIR, AND BLOCKING SMOKE IN HIGH-RISE BUILDING STAIRWELL
Document Type and Number:
WIPO Patent Application WO/2018/032498
Kind Code:
A1
Abstract:
Provided is a method for pressurizing, supplying air, and blocking smoke in a high-rise building stairwell; the high-rise building has a plurality of stories, and the stories are connected to each other by means of the stairwells (4); a plurality of air supply vents (11) are distributed in the stairwells (4), and the air supply vents (11) are used for supplying air to the stairwells (4). The method comprises the following steps: S1: detecting whether a fire has occurred at each story of a high-rise building; S2: if, in step S1, a fire is detected on a story of the high-rise building, then causing only the two or three nearest air outlets to supply air. The system used by the method comprises a fire detector (1a) and a system controller (1b); if the fire detector (1a) detects the occurrence of a fire on a story of the high-rise building, then a fan (9) and air supply vent (11) are automatically activated by means of linked control. In the method and system it is possible to block, using a smaller amount of supplied air, the smoke generated by the power of the same fire source of any stories on fire from entering the stairwell, thus minimizing the effect of air leaking between stairwells as a result of the number and positions of openings of fire doors between the stairwells.
