Definitions
- the present invention relates to a structural element with controllable heat transfer coefficient U and its use as a wall and / or roof element in buildings or vehicles and a method for controlling the heat transfer coefficient U in such a structural element.
- the heat transfer coefficient U in construction is a specific characteristic value of a component or building material, which in principle indicates its thermal insulation properties. The higher the heat transfer coefficient U, the worse the heat-insulating property of the component or building material.
- the heat transfer coefficient U has become particularly important at the latest since the amended Energy Saving Ordinance (EnEV), which came into force in Germany in 2009, according to which the annual primary energy demand and the specific transmission heat loss of a building to be constructed must comply with certain limit values.
- the heat transfer coefficient U is included in the calculation of the transmission heat loss, which in turn is used in the calculation of the primary energy demand.
- the Energy Saving Ordinance prescribes limits for the heat transfer coefficient U for certain components when they are replaced or newly installed in existing buildings.
- insulation elements which are used for thermal insulation of buildings. These typically consist of one or more insulating layers of insulating material (e.g., foams, foamed polymeric materials). Depending on the nature of the insulating material, a protective layer is applied on the outside of such insulation elements. These insulating elements are used in particular to prevent heat leakage from the interior of a building to the outside. At the same time, a heat flow into a building can also be reduced. According to the state of the art, most of the insulating elements have fixed insulating properties, that is, the insulating property can only be regulated by varying the thickness and / or the number of insulating elements. However, this does not make it possible to react flexibly to current temperatures inside and outside a building.
- DE 10 2006 024 067 A1 describes an insulating element which is particularly suitable for internal and / or external insulation of buildings.
- the insulating properties of the insulating element described there can be changed depending on the desired internal temperature of the building or depending on the outside temperature and / or sunlight, in particular by changing the heat transfer coefficient U and / or the reflection properties of Dämmements themselves.
- the insulating element is provided with an insulating material , which can be changed in its position, so that the insulation used wholly, partially or substantially does not contribute to the insulation of the building.
- the insulating material can be completely or partially compressed in order to release the heat flow through the insulating element completely or partially.
- a major disadvantage of all embodiments of the prior art is that large amounts of material must be moved or compressed, since the surface of the element must be substantially met or free of insulating material.
- a device for insulating and / or solar heating is disclosed. This is applied to the façade of an existing building and consists of a transparent panel, which is placed in front of a wall and thus encloses a defined space with the wall. Within the defined space, a heat absorber of a closed-cell insulating material is arranged. This heat absorber has openings, so that depending on the temperature conditions, a convection flow can form within the device described. In this way, on the one hand by the presence of the insulating material thermal insulation of the building can be achieved, while on the other hand solar radiation is used by the heat absorber to heat the trapped gas volume in the device and deliver this heat on the convection flow to a certain extent on the existing building wall.
- US 2003/0061776 A1 discloses a variable heat transfer coefficient insulating system based on an inflatable structure which responds by changing the volume to changes in the atmospheric temperature. As a result, the heat flow can be controlled.
- AT 380 946 B1 discloses a so-called heat exchange wall, which consists essentially of a surrounded by a tube system insulation board in which a gaseous heat transfer medium can circulate, the circulation can be automatically locked by the special design of the tube system.
- a heat exchange wall which consists essentially of a surrounded by a tube system insulation board in which a gaseous heat transfer medium can circulate, the circulation can be automatically locked by the special design of the tube system.
- an insulating element with switchable insulation behavior is an automatic lock is not necessarily useful because the same temperature differences depending on the weather either a strong insulation or a reduced insulation make sense sense.
- the insulation element described in AT 380 946 B1 is constructed comparatively complicated and accordingly only bad to manufacture.
- the invention is therefore an object of the invention to provide a novel construction element that minimizes the energy consumption of a building by helping to control its heat balance.

- the third aspect of the present invention solves the underlying object by a method for controlling the heat transfer coefficient U in a construction element (1) according to the invention, comprising the steps
- the present invention is based on the finding that the heat transfer through a construction element (1) of the type described can be regulated by forming and controlling an internal convection flow.
- the construction element (1) according to the invention it is also possible in a technically simple manner to significantly minimize the energy consumption of a building and thus optimally exploit the prevailing temperatures inside and outside a building. It is advantageous that, according to the present invention, the heat transfer coefficient U can be regulated as required and independently of the prevailing indoor / outdoor temperatures. Thus it can be achieved by the inventive design of the construction element (1) that during the cooler night hours increased discharge of heat from the building is enabled, while at high outdoor temperatures during the daytime and at low outdoor temperatures in winter one of the regulations for adequate thermal insulation appropriate insulation effect can be ensured.
- the present invention relates to a structural element (1) with controllable heat transfer coefficient U, comprising
- first plate (3) a first plate (3) and a second plate (5) which are opposite to each other and which are arranged at a distance A from each other in the frame (7), wherein by the first plate (3), the second plate (5) and the frame (7) is defined as a closed volume V filled with at least one gas,

- first cavity (15) and the second cavity (17) communicate via the upper space (11) and the lower space (13) so as to communicate between the first cavity (15) and the second cavity (17) the upper intermediate space (11) and the lower intermediate space (13) can flow a convection flow
- At least one means for controlling the convection flow which is arranged for the upper intermediate space (1 1) and / or for the lower intermediate space (13).

- the configuration of the first and second plates (3, 5) will be described in more detail below.
- the shape of the construction element (1) can be chosen freely within wide limits and adapted to the requirements of its installation situation and / or use.
- a preferred embodiment is an approximately cuboidal element.
