Abstract (en)
[origin: EP2995877A2] The present application discloses an air curtain combined with a mechanical extraction of smoke, released by a fire in a room, which comprises a vertical or horizontal plane jet with appropriate slope, generated by a cylindrical rotor fan enclosed in a housing with two openings, one outside the room and the other on the lower side. In this manner, this technology is useful for confining the flow of smoke, produced in fire situations in buildings, only to the room of fire origin, without the need of closing the passage ways with smoke doors, and without being necessary to set speeds for the air flowing through those passages, within the same range of the speed of the smoke flow, this being the technical problem solved. The usage of this system is compatible with current smoke exhaust means to be applied to buildings, and makes it unnecessary to inflate fresh air inside that room, once this is now done through the passage way, which remains protected by the air curtain.
