Abstract

Un parement de façade est composé d'éléments qui comprennent un accumulateur d'énergie (1) et une isolation (2). L'accumulateur contient un matériau capable d'accumuler de grandes quantités d'énergie par changement de phase (solide-liquide ou liquide-gazeux) ou par changement de ses propriétés (dur-mou). Pour que l'accumulateur se charge de l'énergie du rayonnement solaire, l'accumulateur et l'isolation prennent une position réciproque où l'acumulateur est exposé au soleil et thermiquement isolé de l'intérieur (3) du bâtiment. Pour décharger l'accumulateur, l'isolation est agencée entre l'accumulateur et l'environnement (4), ce qui fait que celui-ci est thermiquement relié au bâtiment. Le déplacement mutuel de l'accumulateur et de l'isolation peut se faire par un mouvement de rotation. Dans toutes les positions, l'isolation protège le bâtiment des portes de chaleur et d'un rayonnement solaire indésirable. L'effet peut être accru par un revêtement réfléchissant des surfaces (5, 6) de l'isolation ou en donnant aux surfaces de l'isolation tournées vers l'accumulateur une section transversale parabolique.A facade cladding is composed of elements which include an energy accumulator (1) and insulation (2). The accumulator contains a material capable of accumulating large amounts of energy by phase change (solid-liquid or liquid-gas) or by change of its properties (hard-soft). In order for the accumulator to charge itself with the energy of solar radiation, the accumulator and the insulation assume a reciprocal position where the accumulator is exposed to the sun and thermally insulated from the interior (3) of the building. To discharge the accumulator, the insulation is arranged between the accumulator and the environment (4), which means that the latter is thermally connected to the building. The mutual displacement of the accumulator and the insulation can be done by a rotational movement. In all positions, the insulation protects the building from the doors from heat and unwanted solar radiation. The effect can be increased by a reflective coating of the surfaces (5, 6) of the insulation or by giving the surfaces of the insulation facing the accumulator a parabolic cross section.

Description

Beschreibungdescription
Energiespeichernde, den Wärmefluss steuernde Fassadenverklei¬ dungEnergy-storing facade cladding that controls heat flow
Die Erfindung betrifft eine aus Elementen aufgebaute Fassaden¬ verkleidung für die Nachrüstung bestehender oder den Einbau in neue Gebäude hauptsächlich im Nicht-Wohnungssektor. Die Fassa¬ denelemente haben zum Zweck, erstens die Wärmeströme durch die Fassade den Bedürfnissen der Gebäudebenutzer anzupassen, d.h. Sonnenstrahlung zu Heizzwecken zu nutzen, oder aber sie fern¬ zuhalten, wenn sie unerwünscht ist. Zweitens soll das Gebäude gegen Wärmeverluste isoliert werden und drittens soll für die anfallende Energie ein Speicher zur Verfügung gestellt werden.The invention relates to a facade cladding constructed from elements for retrofitting existing or installing in new buildings mainly in the non-residential sector. The purpose of the facade elements is, firstly, to adapt the heat flows through the facade to the needs of the building users, i.e. To use solar radiation for heating purposes, or to keep it away if it is undesirable. Secondly, the building is to be insulated against heat loss and thirdly, a storage facility is to be made available for the energy generated.
Fassadenverkleidungen, die ihre Wärmedurchgangseigenschaften den Bedürfnissen der Gebäudebenützer anpassen, sind bekannt, beispielsweise mit Hilfe von Folien, wie im CH-Patent 610 037 dargelegt ist. Bekannt ist auch die Verwendung der Gebäudewand als Energiespeicher, z.B. die Trombe-Wand, wobei die Trombe- Wand auch ein Speichermedium enthalten kann, das auf Phasenum¬ wandlung beruht, wie z.B. dargelegt in Telkes M. , DOE/ISES-AS 2nd Natl. Passive Solar Conf. 1978, Vol. 2, p. 283.Facade claddings that adapt their heat transfer properties to the needs of building users are known, for example with the aid of foils, as set out in Swiss Patent 610 037. It is also known to use the building wall as an energy store, e.g. the Trombe wall, the Trombe wall may also contain a storage medium based on phase change, such as set out in Telkes M., DOE / ISES-AS 2nd Natl. Passive solar conf. 1978, vol. 2, p. 283.
Die Trobe-Wand ist jedoch ein schwerfälliges Bauelement und hat auch bei Verwendung von Latentspeichermedien eine zu ge¬ ringe Speicherfähigkeit. Es stellte sich die Aufgabe, ein industriell herstellbares, flexibles Bauelement zu entwickeln, das die Funktionen passive Energiegewinnung, Speicherung, Iso¬ lation und Sonnenschutz in einem verwirklicht und einfach zu montieren und zu bedienen ist.However, the Trobe wall is a cumbersome component and has too little storage capacity even when using latent storage media. The task was to develop an industrially producible, flexible component which realizes the functions of passive energy generation, storage, insulation and sun protection in one and is easy to assemble and operate.
Diese Aufgabe wurde gelöst, indem das Speichermedium in Form eines festen oder beweglichen Elementes in die Fassadenver¬ kleidung integriert wird und mit einer beweglichen Isolations- Schicht kombiniert wird, die das Speichermedium je nach Bedarf gegen aussen oder gegen innen thermisch abschirmt. Diese Ele¬ mente können in Normgrössen gefertigt oder für individuelle Ab¬ messungen hergestellt werden. Sie können, insbesondere bei be¬ stehenden Gebäuden, an der Aussenwand angebracht werden oder aber, bei Neubauten, direkt in die Wand integriert werden. Gegen aussen sind sie vorzugsweise mit einer einfachen oder doppelten Verglasung abgedeckt, die .einerseits zum Treibhaus¬ effekt führt und damit die passive Energieausbeute erhöht, andererseits aber auch Schutz vor Witterungseinflüssen bietet.This object was achieved by integrating the storage medium in the form of a fixed or movable element in the facade cladding and with a movable insulation Combined layer that thermally shields the storage medium from the outside or from the inside as required. These elements can be manufactured in standard sizes or manufactured for individual dimensions. They can be attached to the outer wall, particularly in the case of existing buildings, or, in the case of new buildings, can be integrated directly into the wall. On the outside, they are preferably covered with single or double glazing, which on the one hand leads to the greenhouse effect and thus increases the passive energy yield, but on the other hand also offers protection from the weather.
Gemäss Anspruch 1 kann die Isolation den Speicher gegen das Ge- bäüdeinnere abschirmen, wenn der Speicher entladen ist und durch eintreffende Sonnenstrahlung aufgeladen werden soll. In dieser Stellung ist die Isolation auch, wenn das Gebäude an heissen Tagen vor unerwünschter Erwärmung geschützt werden soll. Ist der Speicher indessen geladen, schieben sich die Iso¬ lationselemente zwischen ihn und die Aussenseite. Er ist da¬ durch davor geschützt, Energie an die Aussenwelt zu verlieren und kann sie stattdessen ans Gebäudeinnere abgeben.According to claim 1, the insulation can shield the store from the inside of the building when the store is discharged and is to be charged by incoming solar radiation. The insulation is also in this position if the building is to be protected against undesired heating on hot days. If the memory is loaded, however, the insulation elements slide between it and the outside. This protects him from losing energy to the outside world and can instead release it to the interior of the building.
Die Ansprüche 4 bis 6 definieren in Betracht kommende Speicher¬ medien: konventionelle Latentspeichersalze mit Fest-Flüssig- Umwandlung, Medien mit Verdampfung in den interessierenden Temperaturbereichen (z.B. Kältemittel oder Kunststoffe, die unter beträchtlicher Energieaufnahme erweichen und direkt, d.h. ohne Umhüllung, das Bauteil bilden können.Claims 4 to 6 define possible storage media: conventional latent storage salts with solid-liquid conversion, media with evaporation in the temperature ranges of interest (for example refrigerants or plastics which soften with considerable energy absorption and which form the component directly, ie without wrapping) can.
Eine reflektierende Beschichtung auf einer oder beiden Seiten der Isolationsschicht (Ansprüche 2 und 3) erhöht die Wirksam¬ keit, indem auch Energieeinflüsse, die sich über Strahlung abspielen, unterbunden werden.A reflective coating on one or both sides of the insulation layer (claims 2 and 3) increases the effectiveness by also preventing energy influences that take place via radiation.
Eine bevorzugte Ausführungsforτn nach Anspruch 7 besteht in der Ausbildung der Isolationseleraente als halbzylinderförmige Schalen, die sich um feste, stangenförmige Speicherelemente rotierend verschieben können. Haben die Innenflächen, wie An¬ spruch 8 lehrt, parabolischen Querschnitt mit den Speicher- Stangen im Brennpunkt, ist die Energieausbeute wegen der Strahlungsbündelung besonders hoch.A preferred embodiment according to claim 7 consists in the formation of the isolation elements as semi-cylindrical Shells that can rotate around fixed, rod-shaped storage elements. If the inner surfaces, as claim 8 teaches, have a parabolic cross section with the storage rods in the focal point, the energy yield is particularly high because of the radiation beam.
Die Rundheit der erwähnten Isolations-Schalen wird nach An¬ spruch 9 auch ausgenützt, um mittels einer Verzahnung die An¬ triebsmomente für die Verschiebung zu übertragen.The roundness of the insulation shells mentioned is also used according to claim 9 in order to transmit the drive moments for the displacement by means of a toothing.
Eine andere Ausführungsform beschreibt Anspruch 10: Speicher und Isolation bilden ein gemeinsames Element, welches durch Kippen um eine Drehachse die beiden von Anspruch 1 vorge¬ schriebenen Stellungen ermöglicht.Another embodiment describes claim 10: memory and insulation form a common element which, by tilting about an axis of rotation, enables the two positions prescribed by claim 1.
Es zeigt:It shows:

Gleiche Funktionsbauteile sind in den drei Figuren mit den sel¬ ben Bezugsziffern versehen. Fig. 1 zeigt die Ausführungsform mit festen Speicherstäben 1 und um Achse 8 drehbaren Isolationsschalen 2 im Querschnitt, wobei die Fassadenelemente in diesem Falle an der Aussenmauer 10 eines Gebäudes hinter einer Verglasung 11 angebracht sind. Die nicht gezeigte seitliche Befestigung der Speicherstäbe bzw. Lagerung der Isolationsschalen erfolgt in herkömmlicher Weise. Die Uebertragung der Drehbewegung kann ebenfalls in herkömmm- licher Weise erfolgen, z.B. mittels Ketten, Zahnstangen, oder aber auch mit einer in Fig. 2 gezeigten Verzahnung 9 der Schalenaussenflache 6 , die sich auch auf die beiden Stirnseiten beschränken kann. Fig. 2 zeigt auch die Ausbildung der Schalen¬ innenflächen 5 als reflektierende Parabolkörper mit den Spei¬ cherstäben im Brennpunkt, wobei die parabolische Verspiegelung sowohl- die von der Sonne eintreffende Strahlung gebündelt dem Speicher zuführt als auch die vom Speicher abgegebene Strahlung zum Gebäude lenken kann, je nach Stellung der Isolationsschalen.Identical functional components are provided with the same reference numbers in the three figures. 1 shows the embodiment with fixed storage rods 1 and insulation shells 2 which can be rotated about axis 8, in cross section, the facade elements in this case being attached to the outer wall 10 of a building behind glazing 11. The lateral attachment of the storage rods or storage of the insulation shells, not shown, is carried out in a conventional manner. The rotary movement can also be transmitted in a conventional manner, for example by means of chains, toothed racks, or else with a toothing 9 of the shell outer surface 6 shown in FIG. 2, which can also be limited to the two end faces. 2 also shows the design of the inner shell surfaces 5 as reflecting parabolic bodies with the storage rods at the focal point, the parabolic mirroring both bundling the radiation arriving from the sun and guiding the radiation emitted by the storage to the building , depending on the position of the insulation shells.
Fig. 3 zeigt eine andere Ausführungsform, bei der Speicher und Isolation zusammen ein lamellenähnliches Bauteil bilden, welches um die Achse 8 gekippt werden kann. FIG. 3 shows another embodiment in which the storage and insulation together form a lamella-like component which can be tilted about the axis 8.
