Document Type and Number:
WIPO Patent Application WO/2022/092989
Kind Code:
A1
Abstract:
The present invention relates to an in-building access path installation type smoke control system. The system is installed to be openable/closable in an access path inside a building and comprises: a door case including a suction hole and a discharge hole; a door nozzle which is installed inside the door case and sprays water supplied from the outside; and a door body including a negative pressure inducer which allows water sprayed from the door nozzle to pass therethrough, generates negative pressure according to the Venturi effect while water is passing therethrough, suctions gas around the door case through the suction hole, mixes suctioned gas and water and causes same to descend toward the discharge hole. The in-building access path installation type smoke control system of the present invention configured as above can form negative pressure when fire breaks out, suction surrounding smoke and toxic gas, and mix same with water to discharge, thereby significantly reducing concentration of smoke and toxic gas, securing visibility, and minimizing loss of lives by providing lighting to induce quick evacuation during a blackout. In addition, the system can cool a fire door and a fire shutter to prevent damage or thermal deformation caused by flames, thereby properly maintaining a function of preventing fire, such as preventing spread of fire and securing as much evacuation time as possible.
