PRESSURIZATION SYSTEM FOR A STAIRWELL
Pressurization system (100) for a stairwell comprising a ventilating casing(1) for supplying air from the external environment provided with a duct(2) connected to the ventilating casing (1), having an external portion (2') for supplying air comprising at least one smoke sensor (20) and an internal portion (2") for supplying air through an internal wall of the stairwell, at least three pressure sensors (4), a control panel (5) electrically connected to the ventilating casing (1), the pressure sensors (4), the at least one smoke sensor (20) and a manual control panel (6), said system (100) being characterised by the fact that the control panel (5) in turn comprises- a battery power supply unit- a programmable logic controller for the control and command of electronically commutated motors of the plurality of fans (10) positioned in the ventilating casing (1);- corresponding motor protectors and power contactors for the plurality of fans (10) positioned in the ventilating casing (1);- an interface with a building management system,and by the fact thatthe ventilating casing (1) comprises one or more additional fans (10) providing the redundancy function.
