Abstract: The invention relates to an axial ventilation device comprising at least three axial fans disposed at the ends of a polygon. According to the invention, a single drive shaft is adapted to rotate at least the shafts of two axial fans. The invention also relates to a premises equipped with such an axial ventilation device.

Abstract: The invention relates to a device for securing a leak of fluid from equipment containing a pressurised fluid. The device comprising a gas-tight containment device disposed around the equipment and defining a volume, Vconf, between the inner surface of the sealed containment device and the outer surface of the equipment. A vent is formed by one or more ports in the sealed containment device, each port being defined by its cross-section and shape. According to the invention, the volume, Vconf, the cross-section and the shape of each port are configured such that, in the event of a leak of flow rate Qf, the fluid is discharged through each port in the form of a turbulent jet.

Abstract: The disclosure first relates to a room comprising an inner space delimited by an upper wall, a lower wall and side walls, the room being provided with a ventilator, the ventilator including: an extractor operably extracting air from the inner space towards the outside of the room, arranged on one side wall; and air intakes on the other side walls. The disclosure also relates to a method for ventilating a room including an inner space delimited by an upper wall, a lower wall and side walls, the method including the extraction of air from the inner space to the outside of the room by an air extractor arranged on one side wall, and the entry of air via air intakes arranged on the other side walls. The disclosure further relates to an air intake adapted to perform the method above.
