Description

Wind ventilation and / or energy generation device
for buildings

The invention relates to a wind ventilation and / or energy generation device for buildings.

It is well known that especially in densely built-up urban areas, especially in heavily built-up areas Exposure to sunlight the ventilation conditions deteriorate significantly. Even if even above the roofs if a wind grazes, this generally does not lead to an improvement in the ventilation conditions in the lower apartments, least of all in the interiors

of houses and winter gardens. In principle, ventilation and air conditioning systems can also be installed in private houses but this usually fails for cost reasons and causes additional energy consumption.

Another problem nowadays is the constantly increasing energy costs. Therefore, often tried new sources of energy, such as solar cells or wind power plants to make a contribution to the energy supply. The possibility of generating energy using wind turbines is still at the beginning. In particular, the use of energy by means of wind turbines is proposed Not conceivable, especially because of the space required for this in the urban area.

The object of the invention is therefore to create a device with which, in an extremely energy-saving manner, it is possible to ventilate building spaces as well as to generate energy using air movements. The object is according to the invention in accordance with the characterizing part of the claim
1 specified features solved. Advantageous refinements of the invention are specified in the subclaims.

The device according to the invention ensures for the first time in the simplest manner that alternatively or, cumulatively, in buildings, ventilation of the interior spaces is possible using wind energy is or that instead of ventilation or in addition the wind movement is still used for energy utilization can be. According to the invention, this is

makes possible that on the one hand a wind deflector for receiving the wind and wind on the roof of a building Air movement is provided, and that on the other hand there is an air shaft guided through the interior of the building connects. Starting from this air shaft, the wind deflection device can then be used via a distribution system introduced moving air to the building interiors including terraces and balconies. As shown, alternatively or in addition to this, the air moved through the air duct can also be used as a drive a wind turbine arranged in the air shaft to generate energy. The electricity generated in this way can, for example, heat a hot water tank

In an advantageous embodiment according to claim 2 is an automatically adjustable wind guide device in the wind provided so that an alignment of the air inlet opening to the air shaft in changing wind conditions takes place in relation to the wind direction.

In a particularly preferred embodiment according to An Spruch 3 or 4 it is provided that at least one preferably two air passage openings lying parallel to the gable are provided on the wind deflector.

Under normal wind conditions, the wind can then rise along the inclined roof surface up to the gable and there it enters the vertically downward air duct via the air passage opening.

In one embodiment of the invention according to claim 6 Furthermore, a deflection and closure device is provided on the wind deflection device in order to prevent that the wind entering at one air passage opening can exit at the opposite air passage opening,

but is deflected down into the air shaft.

In order to increase the air flow speed, it is provided in an advantageous embodiment according to claim 10, that the air shaft tapers towards the bottom.

To ensure energy generation and thus air flow through the air shaft even if a ventilation of the building interiors is not carried out, is also in a development according to claim 13 provided that a closable wind outlet duct leads from the air shaft to the outside of the building. If there is wind This ensures constant air circulation through the air shaft.

Further advantages, details and features of the invention emerge from the following with reference to the drawing illustrated embodiment. Show in detail

In the drawings, a building 1 with an attic, a cellar and several not shown in detail in between Floor 3 shown. It is a common house with a pitched roof 5. To allow air movement outside, in particular to use the wind for ventilation purposes as well as for energy generation purposes, a wind deflection device 9 is provided on the roof top along the gable 7, which essentially from a roof attachment 11 with inclined side surfaces

cheh exists whose angle of inclination is identical to the angle of inclination of the sloping roof 5. This roof attachment 11 is arranged offset vertically upwards to the sloping roof 5, so that on both sides of the gable 7 two parallel opposite air passage openings 13 are thereby formed will.

As can only be seen sketchily from FIG Closing device in the form of a lamella flap device 5 installed below the wind deflection device 9 and the lamella flap device 15 is followed by a vertically downwardly guided air duct 17 which closes its lower end tapers cubically at least in one sectional plane. For example, the wind deflection device extends 9 over practically the entire length of the roof and gable, so several can be seen from there in a side view Conical downwardly tapering air shafts 17 may be provided.

At the lower end 18 of the air shaft 17 then connect ventilation lines 19 to the to be ventilated Building interiors or lead to terraces and balcony facilities. With the respective user you can at the end of the ventilation ducts 19 then closure devices can be provided in order to ventilate the wind respectively on and off.

As can also be seen in FIG. 1, both in the roof space and at the lower end of the shaft 17 or even a wind turbine 21 can be installed in the ventilation line 19, which during the air circulation Generated electricity for the in-house energy supply via a downstream generator 23. What is required is, for example

wise that a hot water supply is heated via the generator or the energy is transferred to an electricity storage unit will.

How this device works is explained in more detail below.

In the wind conditions shown in Fig. 1, where the wind according to the arrow representation from the left onto the building roof blows, the air masses moved in this way are deflected upwards on the top of the sloping roof 5 and enter the wind deflector 9 through the left air passage opening 13. The one below the wind deflector 9 provided lamella flap device is tilted so that it did according to the neuter wind conditions each pivoted so that the wind entering through an air passage opening does not on the opposite air passage opening can exit again, but down into it subsequent air shaft 17 is deflected.

The air shaft 17, which tapers conically downwards, still increases the speed of air movement increased, so that at the end of the ventilation lines 19 when entering the interior spaces to be ventilated a sufficient Supply and ventilation with fresh air is possible. The same applies, of course, to balcony and terrace areas, as well as so-called winter gardens.

Alternatively or additionally, the wind turbine 21, which is preferably provided in the lower area, can then be used for the ventilation of the building rooms, energy to supply the in-house energy needs can be obtained.

/in

For example, a power storage circuit can be used via the generator or a hot water supply can be operated.

In order to enable energy to be generated even when the ventilation ducts 19 are closed in windy conditions, at least one closable wind outlet duct 25 is also provided, via which the moving air from the air shaft 7 can be released to the outside again.

The arrangement described works of course also when the wind is not only transversely at a 90 ° angle to the Building longitudinal direction, but also falls obliquely. Should the wind conditions fluctuate so that the wind in the essential to the embodiment shown according to Fig.

1 blows from the other side of the roof, i.e. from the right, then the lamella flap device described above 15 automatically pivoted into its opposite position so that the wind entering from the right is opposite to the left lying air passage opening cannot escape again.

In contrast to the roof attachment 11 shown, it is also conceivable that this is not formed at an oblique angle like the roof itself, but only from a horizontal zontal coverage. As a result, the air passage openings 13, each from an elongated The opening gap is still enlarged and a so-called funnel effect is also generated, which in terms of volume a larger and stronger air movement can be diverted into the interior of the building.

The device described above for ventilation and / or

Energy generation can therefore be achieved without major building measures that are visible from the outside and that are detrimental the building and cityscape.
