    DOUBLE FACADE
    The invention relates to a double facade for multi-storey houses, in which between an inner wall and an outer wall, which have both glass panes, a top and bottom and laterally between the inner and outer wall closed space, the outer wall below an inlet opening and has an outlet opening for air at the top, which flows upwards in a heat input into the space therein.
    In known double facades of this type, the outer wall (secondary facade) of the inclusion of environmental effects and solar heat input, wind loads or weather conditions. The inner wall (primary facade) forms the conclusion of a useful space and usually also has a thermal insulation function. The space can be about 20 cm outward to several meters wide to the outside. Furthermore, a double facade can be designed as a supply or exhaust air facade. On the outside of the inner wall may also be provided a sunlight reflecting sunscreen.
    The invention has the object to extend the functions of such a double façade.
    According to the invention this is achieved in that in the space of the double-facade at least one impeller is mounted in the upward airflow, which is in drive connection with a power generator. Here, the energy of the air flow is transformed into electrical energy, which can then be harnessed.
    A further development may be that several impellers are in drive connection with only one power generator. This reduces the number of power generators and thus the cost of materials compared to the use of multiple power generators with the same overall performance as just a power generator.
    Further, a plurality of impellers may be arranged one behind the other on the drive shaft of at least one power generator. As a result, the drive power for each generator can be increased with the same air flow.
    Then it is possible that the drive shaft is at least one power generator via a common transmission with output shafts of a plurality of impellers in drive connection. This also makes it possible to improve the efficiency of the conversion of the air flow strength into electrical energy with only one power generator.
    Preferably, it is ensured that the or each impeller has blades in the manner of a propeller and is mounted so that it is flowed through by the rising in the intermediate space air flow coaxially to its axis of rotation. Such an impeller, which corresponds to a wind turbine, has a simple structure. At a relatively small distance of the facade walls and correspondingly small impeller diameter, a plurality of impellers may be mounted at the same height parallel to the axis side by side.
    A particularly advantageous embodiment may be that the axis of rotation of the or each impeller in the gap is horizontal, that each impeller has over its entire axial length extending wings, which is convex on one side and concave on the other side are curved, and that when using only one impeller whose axial length is greater than half the distance of lateral partitions of horizontally adjacent interstices of the double facade. The or each such impeller formed corresponds to a roller fan when it is not driven to generate an air flow by a motor, but is itself driven to generate a torque by an air flow. In comparison to the use of several wind turbines with the same overall drive power as that of a roller fan, its construction and assembly are simpler.
    Another possibility is that the energy generated by the single power generator or 1 17 Austrian Patent Office AT12 728U1 2012-10-15 further power generators via the public power grid or directly to a power consumer is supplied. In this embodiment, the electrical energy generated can either be supplied to any power consumer connected to the public power supply network or only to one or more specific power consumers.
    The invention will be described below with reference to the accompanying schematic drawings of exemplary embodiments of the invention double facades. 1 shows a vertical cross section through a double facade according to the invention, [0013] FIG. 2 shows the section AA of FIG. 1 in a simplified form, [0014] FIG. 3 shows an enlarged detail of FIG. 4 shows a plan view of a plurality of impellers, each of which drives its own power generator and, together with these and adjoining sunshade boxes, are installed side by side in a horizontal plane in an intermediate space of the double façade in the form of modules (modules), [0016] FIG 4, but with only one impeller, which is modified with respect to those according to FIGS. 1 to 4 and drives only one power generator, and FIG. 6 shows the section BB of FIG. 5.
    Referring to Figures 1 and 3, a multi-storey house (e.g., skyscraper) has on each south-facing floor an inner wall 1 (primary facade) and an outer wall 2 (secondary facade). Each inner wall 1 has a hollow insulating glass pane 3 (see FIG. 3) in a frame 4. Each outer wall 2 has a simple glass pane 5 in a frame 6.
    The inner walls 1 define outwardly each a usable space 7, e.g. Office or living room. The utility rooms 7 are separated by floor ceilings 8. Between each inner wall 1 and outer wall 2 is a gap 9. The distance of the walls 1 and 2 is about 35 cm to 40 cm or more. In the lower end of each outer wall 2, an air inlet opening 10 and in the upper end of an air outlet opening 11 is present. The superposed gaps 9 are separated by partitions 12, which are each at the level of a floor ceiling 8. On both sides of the spaces 9 are each bounded by a partition 13. The distance between the partitions 13 of a gap 13 is about 135 cm, wherein for each work space 7 a plurality of intermediate spaces 13 at the front of the work space 7 can be arranged horizontally next to each other. The interstices 9 are therefore closed, except for the air inlet and outlet openings 10, 11. When a heat input, in particular a solar heat input through the outer wall 2 and / or a heat input through the inner wall 1 in a gap 9 creates an upward air flow 14, wherein the air flows through the lower inlet opening 10 and exits through the upper outlet opening 11 again , In each intermediate space 9, several units 15 (modules) of an impeller in the form of a wind turbine with propeller-like blades and an electric power generator 17 are installed horizontally next to one another (see FIG.
    The upward air flow 14 in one of the interspaces 9 drives all vanes 16 in this space 9 and this in each case via a gear 19 (Fig. 3) each one of the power generators 17 at. The power generated by each power generator 17 can be fed via a power cable 20 into the public power grid, if necessary via a ballast to adapt to the size, frequency and phase of the mains voltage, or fed directly to a power consumer. A preferred power consumer would be an electric motor for driving the compressor in a compression refrigeration system or an electric heater in one of the utility rooms 7 of the house.

In each sun protection box 18 is a Venetian blind 23, which is designed to be light-reflecting on its outer surface. The reflected sunlight with the Venetian blind 23 lowered contributes in addition to the heating and buoyancy of the air in the space 9 at. Alternatively to the illustrated embodiment, all impellers 16 could drive in a space 9 together via a corresponding gear only a more powerful power generator.
