Abstract (en)
[origin: EP4234871A1] The present invention relates to an in-building access path installation type smoke control system. An in-building access path installation type smoke control system is openably and closably installed in an in-building access path and includes a door casing having an intake port and a discharge port, a door nozzle installed in the door casing and configured to spray water supplied from the outside, and a main door body including a negative pressure inducer configured to allow water sprayed from the door nozzle to pass therethrough, generate negative pressure on the basis of the Venturi effect while the water passes therethrough, suck gas at the periphery of the door casing through the intake port, mix the sucked gas with water, and move the gas mixed with the water downward toward the discharge port.
