Abstract

The solar panel, used with or without a heat pump and positioned on a roof, is designed to prevent water condensation. The panel is formed from a U-shaped aluminium sheet measuring 2 X 2 or 1 X 2 metres, with the two vertical limbs bent outwards by 2 centimetres at the top. The inside has a covering of glass or a special foil with a shallow U-shaped profile and the aluminium sheets are retained by 2 or 3 aluminium profile rails secured to the roof. The mode of operation of the panel is controlled by an expansion device filled with an expansion fluid and used to open and close the panel.

Die seitherigen Konstruktionen zur Gewinnung von Energie von der Sonne oder aus den Medien Luft, Wasser und Erdboden mussten sich entweder des Prinzips des Solarkollektors oder des Prinzips des Abaorbers bedienen.Sollten diese beide Prinzipien in einer konstruktion vereinigen, so waren sie stets zu Kompromissen gezwungen, welche die jeweilige Hochwirksamkeit nicht erreichen liessen, und ausserdem einen hohen Aufwand an Material- und Montagekosten verursachten.Sollten sie auf, oder in, oder an Stelle eines Daches angebracht werden, so bestand stets die gefahr dachzerstörenden Kondenswassers, welche nur durch zusätzliche Vorrichtungen gebannt werden konnte.Alle diese Nachteile beseitigt die vorgelegte Erfindung, welche sich für Altbauten wie für Neubauten gleichermassen gut eignet.

" The previous constructions for the production of energy from the sun or from the media air, water and soil had to use either the principle of the solar collector or the principle of the Abaorber. Should these two principles be combined in one construction, then they were always forced to compromise, which did not allow the respective high effectiveness to be achieved, and also caused a high expenditure of material and installation costs. Should they be installed on, in or in place of a roof, there was always the risk of roof-destroying condensation, which can only be prevented by additional devices All of these disadvantages are eliminated by the present invention, which is equally suitable for old and new buildings.

Beschreibung: Der Flachbehälter(Fb)besteht im Prinzip aus einem U förmige@ Aluminiumblech in den Rastermassen 2x2 und 1x2 Metern.Description: The flat container (Fb) basically consists of a U shaped @ aluminum sheet in the grid dimensions 2x2 and 1x2 meters.

Seine beiden senkrechten Schenkel sind 2cm nach aussen ab gebogen. Auf ihnen ist die abdeckung (Srezialfolie oder Glas mit einem schmalen U Profil und Schrauben befestigt.Solche Rasterteile können in beliebiger länge, je nach Dach- oder Wandausdehnung dachziegelartig aneinander gereiht werden. Sie werden jeweils auf 2 oder 3 Alu Profilschienen, welche durch die dachbedeckung in dessen Unterkonstruktion geschraubt werden( sonst wird die Dachbedeckung in keiner Weise tangiert) befestigt.Ein solcher Bb wird mit einer 2cm dicken Glaswolleisolierung versehen, welche mit einem zweiten Alublech abgedeckt isto So kann das bei Absorbertätigkeit entstehende Kondenswasser nach unten aus dem dort offenen Bb austreten, ohne das Dach zu zerstören.Its two vertical legs are bent outwards by 2cm. On them The cover (Srecial foil or glass is fastened with a narrow U profile and screws. Such grid parts can be strung together like roof tiles in any length, depending on the roof or wall extension The substructure must be screwed (otherwise the roof covering is not affected in any way). Such a port is provided with a 2 cm thick glass wool insulation, which is covered with a second aluminum sheet destroy the roof.

Das Entscheidende dieses Fb,s liegt aber in seiner oberen und in seiner unteren Abschlusskonstruktion.The decisive factor in this Fb, s, however, lies in its upper and in its lower end construction.

In ihr befindet sich jeweils ein auf einer Achse bewegliches Alublech in den Massen des lichten Querschnittes des Fb @.In each case there is an aluminum sheet that can move on an axis in the dimensions of the clear cross-section of the Fb @.

Dieses Alublech wird durch einen Ausdehnungsbehälter in Schliess-oder Öffnungsstellung gebracht.Er ist im Fb montiert, mit einer Ausdehnungsflüssigkeit gefüllt, welche im Temperaturbereich von plus 20 Grad bis plus 80 Grad Eclsius arbeitet. Dadurch wird die automatische Umschaltung vom hochwirksamen Kollektor zum hochwirksamen Absorber bewirkt.This aluminum sheet is closed or closed by an expansion tank It is mounted in the Fb, with an expansion fluid filled, which works in the temperature range from plus 20 degrees to plus 80 degrees Eclsius. This makes the automatic switchover from the highly effective collector to the highly effective Absorber causes.

Eine Abdeckung des oberen und unteren Abschlussteiles des Fb's schützt diesen Mechanismus sowie den Inhalt des ganzen Fb's aegen Verschmutzung, Schneetreiben und Vereisung. Siehe Abbildungen.A cover of the upper and lower end part of the Fb protects this mechanism as well as the contents of the whole Fb's prevent pollution, blowing snow and icing. See pictures.

Bei Lichteinstrahlung erwärmt sich der Inhalt des Fb's und somit auch die Flüssigkeit des Ausdehnungs@@behälters.Bei Er#eichen von plus 20 Grad celsius, als der optimalen Anfangstemperatur für die Solarkollektorwirkung,schliesst nun der oben beschrieben Mechanismus den Fb oben und unten dicht, so dass die volle Kollektorwirkung bis über plus 80 Grad Celsius erreicht werden kann.Sinkt die Temperatur in dem Fb unter 20 Grad Celsius so öffnet der Mechanismus wieder vollautomatisch. Nun kann die im Fb eingebaute Anordnung als Absorperfläche gegeb die dauernd von oben nach unten durchströmende Luft voll wirksam werden. Dies wird besonders bei völlig bedecktem Himmel oder bei Nacht der Fall sein. Der Absorber wird nun mittels Wärmepumpe, welche grösstenteils mit Nachtstrom beschickt wird, arbeiten.Vereisungnn an der Absorberfläche sind völlig unbedenklich.Sie tauen sehon bei geringer Lichteinstrahlung ab.Das Kondenswasser fliesst auf dem zweiten Alublech nach unten aus dem Fb, der bei diesen Bedingungen offen ist.When exposed to light, the contents of the Fb heats up and thus also the liquid in the expansion tank. When it reaches plus 20 degrees Celsius, which is the optimum starting temperature for the solar collector effect, the mechanism described above now closes the Fb tightly at the top and bottom, so that the full collector effect can be achieved up to plus 80 degrees Celsius. If the temperature in the Fb falls below 20 degrees Celsius, the mechanism opens again fully automatically. Now the built-in in the FB Arrangement as an absorber surface gives the air flowing through continuously from top to bottom fully effective. This will especially be the case when the sky is completely overcast or at night. The absorber will now work by means of a heat pump, which is largely fed with night electricity. Icing on the absorber surface is completely harmless. They thaw The condensation water flows down on the second aluminum sheet out of the Fb, which is open under these conditions.

Im Fb ist eine Älu-oder Kupferblechkonstruktion eingebaut, welche aus zwei punktverlöteten Rippenplatten nach der Art eines Flachheizkörpers besteht. Die lichtzugewandte Seite ist schwarz nach dem Prinzip der hochwirksamen Kollektoren und oberfläcghenbearbeitet.Die untere Seite ist glatt, metallglänzend, um so die Wärmeabstrahlung gering zu halten.Zwischen den beiden Rippenplatten fliesst Sole durch eine Umwälzpumpe entwerder direkt zum Wärmetauscher oder durch ein Ventil gesteuert zur Wärmepumpe.Diese Rippenplattenkonstruktion wird ebenfalls in den Rastermassen im Fb montiert, und im Fb verrohrt in Parallel#schaltung.An aluminum or copper sheet construction is built into the Fb, which consists of two point-soldered rib plates in the manner of a flat radiator. The side facing the light is black according to the principle of highly effective collectors and surface machined. The lower side is smooth, shiny metal, so that the Keeping heat radiation low. Brine flows between the two ribbed plates by means of a circulation pump either directly to the heat exchanger or through a valve controlled to the heat pump. This ribbed plate construction is also in the grid dimensions Mounted in the FB and piped in parallel in the FB.

Die beschriebenen Konstruktionen lassen sich aus einheitlichen und einfach zu bearbeitenden Materialien herstellen.The constructions described can be made up of uniform and make materials that are easy to work with.

Sie sind witterungs- und korrosionsbeständig. Ihre Montage auf Dächern oder an Wandflächen ist problemlos. Das optische Aussehen ist nicht störend.
