    active facade
    State of the art
    The invention relates to an active facade system for buildings according to the preamble of patent claim 1.
    Are known on the outer wall of buildings attachable diffusion-open Wärmedämmanordnungen that are particularly suitable for the production of so-called low-energy or passive houses. . ** ·· i · * • · · *
    In the context of heat demand calculations for buildings play among other things the * · · · ♦
    Transmission heat losses across the outer walls of buildings are a crucial i .. ♦ * * ·
    Role. Especially for the dimensioning of the heating system is the reduction of the J
    Transmission heat losses essential. * * * *
    If heating energy is to be saved or, in all seasons, a temperature in the interior of a building is achieved with virtually no significant heating of the building by primary heat sources, then this building, which is insulated by certain measures, is usually called a passive house. This can get along with corresponding insulation with much less heating energy in relation to an uninsulated house.
    A known insulation of a passive house achieves an 80% or even greater energy saving of heating energy. Only about 1 to 2 liters of heating oil per year are needed to heat a passive house per square meter.
    For this, heat bridges must be avoided in the thermal insulation of the outer shell of the passive house, so that a continuous thermal bridge-free and diffusion-open insulation shell must be applied to the masonry of the outer wall. Üblicherweiseweise insulating layers are applied with a thickness between 10 and 20 cm in the form of mineral fiber mats or polystyrene plates on the outer skin of buildings 2 and there usually secured with dowels. Subsequently, the insulating layers are plastered or clad.
    However, this type of construction is problematic in terms of the indoor air conditioning of the building, which is usually done by fresh air through the ventilation through open windows or doors or leaks in the house. As a result, however, the largest heat losses are achieved. Therefore, in the manufacture of passive houses, particular attention is paid to the airtightness of the buildings.
    The use of air for the insulation of buildings is known (WO 97/30316 A1). , * · * ·
    Air is heated to a certain temperature by a complex system and passed through the wall of a building in a single layer. Described is a '· **; • *
    Multi-ply board, in which one or two layers are designed as an insulating layer and an *.: .. · · * of the layers forms an air duct. * * * * ·
    A disadvantage of the known Dämmvorrichtungsanordnungen is that it to. "***
    Mold growth can occur in edges and corner areas of the building, provided that the rooms inside are not sufficiently ventilated. The interruption of the diffusion can lead to problems with the building moisture in the masonry.
    Furthermore, it is disadvantageous that the heating, for example, an air layer for insulation again requires the use of energy, whereby the energy balance of the entire building is adversely affected.
    Also known are various types of heaters that are intended to heat interiors by heating the wall of a building, so that an interior heating system should be omitted. So conventional interior heating systems are to be replaced. However, heat losses to the outside and inwards are to be expected. It must be generated a very high energy consumption to achieve indoor heating over such a heater of except by heating the wall.
    Against this background, the invention has the object of developing an insulation device for a facade so that Transmissionswärmeverfuste be avoided or at least reduced from the interior 3 ago and mold formation is avoided in the interiors despite almost complete airtightness.
    This object is solved by the features of claim 1. The subclaims indicate advantageous embodiments of the invention.
    The invention and its advantages
    The invention according to the features of the main claim, however, has the advantage that the temperature difference between the indoor air and the adjacent. · * **
    Wall is reduced by a temperature control of the wall. II * • * * * * * • Λ
    This temperature control and thus the reduction of the temperature difference between. ♦ · · ·
    Interior and wall is characterized by the arrangement of a tube system between the
    Masonry, so the wall, and achieved the outer insulating layer. Thus, the: *, # * ·
    Heating of the building not mainly from the inside through the use of. * '* Heaters achieved, but mainly the heat transfer from the interior to the outer wall inner surfaces is avoided. This is achieved by balancing the heat loss on the wall outside under a facade insulation.
    In this case, the tube system is designed so that the wall surfaces of the building are heated as completely as possible and over a large area by tubes arranged at suitable intervals. The tubes are arranged on the outside wall outside. Depending on the arrangement of the tubes, these outer wall outer sides of the building are covered with the tube system by at least 30%, in particular from 40% to more than 90%. It does not include the openings and openings such as windows or doors to the outer wall surfaces.
    The positioning of the tubes across the entire building wall surface ensures even tempering of the walls of the entire building, minimizing heating energy requirements, maximizing energy efficiency and optimizing the relative humidity of the wall and the room air. In the tubes are either antifreeze or an antifreeze mixture with shares of water or heat transfer fluid. 4
    The active facade system is designed taking into account the specific building heat demand defined according to the currently applicable standards. Therefore, it can be either as a sole heating system, insofar as the climatic conditions do not require further interior heating and the effect of preventing the heat flow from the interior by the tempering of the outer wall is sufficient, as well as a combination of an existing Heizflächensystems (wall, floor heating, radiators or the like) be installed with the active facade system.
    All types of known insulation systems can be used on the building façade outer surface which is thermally activated with the active facade system.
    The tube system may be formed as a wall heating system, wherein the tubes are for example made of PEX-FBH pipes or PP pipes (polypropylene), PP capillary pipe mats or metallic pipes, so that the wall heating system transfers heat to the outer surface of the building , This so-called wall heater is protected by the application of a wall insulation composite system from heat loss.
    The Wandheizregister, so the tube system is, for example, mechanically fixed by clamping rails or mounting anchors on the outer walls and plastered over the entire surface to peak height with a commercial mineral plaster.
    In an advantageous embodiment of the invention, the tubular Wandheizregisterkreis, which takes over the heat delivery to the thermally activated building facade surface, fixed at sufficiently solid structure of existing in the existing building exterior plaster on this plaster by suitable dowels and with a suitable adhesive or plaster mortar to at least the pipe apex, So the farthest from the wall of the pipe side, plastered.
    In particular, an adhesive anchors dowel, which may be made of plastic, used, this adhesive anchors dowel is suitable according to its design for wind load securing wall connection of a thermal insulation composite system to the building wall 5 out. The bonding or attachment of the thermal insulation composite system takes place in this case on the provided with freshly workable adhesive mortar adhesive anchor.
    The wall heating coil, which takes over the heat supply to the thermally activated building façade surface, is hydraulically separated from the interior heating surface circle. The tubular Wandheizregisterkreis is filled in particular with an antifreeze medium and operated. This means that in the tubes antifreeze is introduced, the water or a heat fluid can be added or admixed in different proportions. The system is therefore permanently protected against frost damage, even during longer periods without heating during the winter phases.
    The loading of the thermally activated building façade surface is carried out with regard to its heat storage capacity and the ideal working time and working phase length for optimized system efficiency. Depending on the decision relevant to efficiency, heat is introduced into the active facade surface or into the interior heating surfaces (radiator, wall, floor heating and the like), or else heat is introduced into both systems. This entry is governed by a scheme specially programmed for this optimized application.
    The heat energy for the Wandheizregister can be made available for example by an air heat pump. Their environmental energy efficiency is high because of the very low system temperatures and the operation even at outdoor temperatures below 0 ° C is very economical.
    In the generation of renewable energy such as solar energy or heat pumps usually heat storage tanks have to be made available in the basement in which the heated water or the heat fluid can be stored. The energy of the memory thus remains unused for possibly longer periods of time.
    According to an advantageous embodiment of the invention, the tubes are therefore designed as a buffer system. As a storage medium, you can either replace the 6 heat storage tanks or complete them. Both the activated building mass and a large part of the liquids otherwise to be stored in the tanks can also be used by the pipe system according to the invention for heating the wall to approximately room temperature.
    In addition, for the temperature control and by the operation of regenerative
    Systems such as solar systems accumulating return liquids of
    thermal solar collectors with a temperature of usually 20 ° C to 55 ° C are used. This allows an increased energy yield of the plant to generate the regenerative energy over the entire heating period and thus to a faster. ····
    Amortization of the plant. Previously unused waste heat can be reduced to low I " Γ
    Temperature level can be fed into the walls and as a heat storage tank * ·; · * * serve. This waste heat can also be produced during the operation of photovoltaic solar cells, the efficiency of which decreases at elevated temperatures. The resulting # heat can be dissipated and used to heat the tube system. *. • · · • * * m
    Outwardly, this serving as a heat storage layer with the tube system is protected by the insulation of known insulation materials, d. H. There is no exchange of heat to the outside, but only inward by the tempering of the wall into the room instead.
    The usually resulting from the inside to outside transmission loss of heat is reduced to the inner wall surfaces for the active facade equipped wall sections to very small amounts, so that any existing inside the building heating surfaces can be operated at greatly reduced system temperatures. For example, an air heat pump used could supply heat to the existing heat distribution system, ie classic radiators, and / or to the active facade.
    The device dimensioning or system temperature of the heaters for the interior can be lower by using the active facade, since the used wall surfaces such as a heat buffer compensate for extreme demand peaks by heat release and take over the majority of the radiator system in the redevelopment version. 7
    The indoor climate is noticeably improved by the measures described. The moisture content decreases in the outer wall area due to the average 5 to 1 K higher component temperature. This can no longer cause condensation-moisture damage. Balanced temperature conditions of the indoor air and the outer wall surface approximate a passive house climate. By the
    Active facade system, a pleasant building temperature is achieved. This increases the comfort for the users of the building.
    It is possible under certain conditions, a timely adjustable 10 temperature control of the individual rooms. A targeted individual room-specific control of the interior temperatures is always possible if the active facade system is installed as a combination of an existing Heizflächensystems with the active facade system. In this case, the active facade takes over the compensation of the transmission losses over the outer wall surface and thus shares 15 of the basic heating load. About the operation of existing, integrated into the system
    Innenheizflächen, so the radiator, wall heating, floor heating and the like, the single-room temperature inside the building can then be varied as needed. 20 The higher insulation value of the old outer wall due to the decreasing component light improves the overall energy balance. Thus, the energy costs can be reduced and a certain independence from the fossil fuels oil and gas can be achieved. The measures mentioned can be carried out in the context of a building renovation program with the installation of a thermal insulation system with a 25 heat exchange even in old buildings. In this case, a deliberately different zone heating due to the optional integration of an existing heating surface system in the building must be taken into account. This has to be taken into account for existing buildings. 30 The tube system can also be used in hot countries to control the temperature of the
    Building wall, in this case, the cooling by appropriate cooling liquids serve. Also for the cooling, a control programmed for this purpose is used. 8th
