AIR INLET SYSTEMS FOR A BUILDING HAVING A CROSSPIECE PROVIDING A CONSTANT FLOW
The invention relates to an air inlet system for ventilating a building, having an air inlet device (10) that has a fastening surface for fastening to a wall (2) comprising an opening leading towards the exterior, said system having a crosspiece (30) comprising a first face intended to be fastened to the wall (2), surrounding the exterior opening, and a second face, substantially on the opposite side, intended to receive the fastening surface of the air inlet device (10), this crosspiece having, from the opening towards the exterior, a direct air passage towards the interior of the building forming a constant flow, and an internal air passage towards said inlet device forming a main flow.
F24F 13/14 - Air-flow control members, e.g. louvres, grilles, flaps or guide plates movable, e.g. dampers built-up of tilting members, e.g. louvre
E06B 7/02 - Special arrangements or measures in connection with doors or windows for providing ventilation, e.g. through double windowsArrangement of ventilation roses
F24F 13/18 - Air-flow control members, e.g. louvres, grilles, flaps or guide plates specially adapted for insertion in flat panels, e.g. in door or window-pane
F24F 13/072 - Outlets for directing or distributing air into rooms or spaces, e.g. ceiling air diffuser of elongated shape, e.g. between ceiling panels
The invention relates to an appliance for a double-flow ventilation device with modulated extraction, or blowing, of air, for an enclosure comprising two groups of at least one room, i.e. a first group and a second group, the appliance being characterised in that it comprises at least one sensor for determining blowing requirements of the first group, and a hub for managing a blowing, or extraction, flow from the second group, comprising at least one means for managing the blowing, or extraction, flow which is controllable according to the blowing requirements of the first group, and at least one sensor for detecting the pressure in the hub, the hub being built into the double-flow ventilation device in such a way as to receive the blowing, or extraction, flow.

The invention concerns a removable impeller (7) designed to be integrated in a fan (1), in particular for controlled mechanical ventilation, and configured in the shape of a wheel provided with a plurality of blades (8) and equipped with locking clips to enable its being fixed on a hub. The invention is characterized in that it includes projecting transmitting clips, arranged proximate a central neck having an axis of revolution that is parallel to that of the wheel, and designed so as to enable the locking clips to be alternately engaged or released. The invention also concerns a fan including such an impeller.
