Description

The The invention generally relates to an opening and / or closing device. In particular, the invention relates to a device for arrangement on or in a passageway (eg in a building envelope). Preferably, the Device provided for ventilation and / or venting of interiors (eg a building interior) and / or for adjusting a passage of a fluid or other Parts. In a preferred embodiment, the device is used as ventilation and / or venting element, in a building envelope (z. B. a concrete wall, a glass facade, a textile façade, etc.) is to be arranged to ventilate an interior and / or to vent.

The Thermal insulation of buildings to save heating energy has in the context of becoming aware for sustainable Development and the increase in the price of energy since the 90s of the twentieth century, and that's why because essentially at the same time legal regulations for thermal insulation of buildings were decided.

Especially older windows and doors represent a weak point in the thermal insulation of buildings, because they are usually not airtight due to leaks are. Advantageously, however, can take place through these leaks air exchange, which is often sufficient to z. B. the humidity in the building interior to maintain a reasonable level, whereby z. B. mold can be avoided.

Sufficient Thermally insulated buildings are common equipped with essentially airtight windows and doors, ensuring a sufficient exchange of air between the building interior and outside air over window and door leaks no longer guaranteed can be. To now z. B. mold or bacterial propagation to avoid or to create a more pleasant room climate, must the building interior frequently or controlled ventilated be what manually, by means of so-called forced ventilation or over ventilation systems can be done.

The manual ventilation and the forced ventilation are usually detrimental, since on the one hand they can lead to excessive ventilation, which with a high heat loss can be connected, and on the other hand can lead to insufficient ventilation, which with the disadvantages described above such. B. mold or an unpleasant indoor climate can be connected.

in the Prior art systems are already known that a controlled ventilation provide and as so-called "controlled living space ventilation" (abbreviation: KWL) be designated. Controlled domestic ventilation must in particular ensure that that excess humidity, Air pollutants and carbon dioxide removed from the building interior be used, and if preferred by good sealing and thermal insulation measures adequate air exchange through window and door leaks no longer guaranteed can be. Controlled domestic ventilation is common with a heat exchanger combined for heat recovery, in the cold season for it Ensures that the outflowing warm room air the inflowing outside air heated and as possible little heat energy the building interior is withdrawn. In the prior art one differentiates between central and decentralized facilities. Central systems usually have a Pipe system containing several rooms ventilate can, while decentralized systems are usually provided to ventilate only one room.

Around outside air in the building interior and exhaust air to the outside to lead to be able to have passages in the Building envelope provided which are sometimes referred to as outside air outlets become. Building envelope passages are mostly in exterior walls (z. B. masonry) and serve in contrast to windows usually not for light admission, but only for ventilation. Known building envelope passages are usually in the form of a plastic tube in a passage of an outer wall provided and inside and outside with a panel provided and often have about it There is also a storm barrier, a fan or a fly screen.

in the Comparison to the building envelope itself (eg windows, walls, etc.) and the heat recovery technology was the building envelope passages in paid little attention to the past.

Especially is disadvantageous in the known building envelope passages, that user in particular the opened state of the building envelope passage neither directly nor visually perceive. Thus many users have even in complete open Condition of the building envelope passage the feeling, to be in a closed room, which negatively affects can affect the health of the user.

In the conventional building envelope passages, it is thus possible that, although there is ventilation, at least it can not be easily perceived by the user. This is sometimes a reason why Many people feel better in rooms that are ventilated through open windows than in air-conditioned rooms, which are ventilated by means of an air-conditioning system with the windows closed.

adversely on the known building envelope passages furthermore, that they are usually unable to do so, even in completely closed ones Condition an air passage substantially completely closed lock. Furthermore, conventional Building envelope passages no, or only insufficient thermal insulation for available are aesthetically most not very appealing and often expensive to wait.
