Description
Stand der TechnikState of technology
Heute übliche Latentwärmespeicher im Bereich der thermischen Solarenergienutzung bestehen aus Behältern, in denen sich ein Wärmespeichermedium wie z.B. Paraffin befindet. Im Innenraum dieser Behälter befinden sich Wärmetauscher, die mit dem Wärmespeichermedium in Kontakt stehen. Durch diese Wärmetauscher findet der Wärmetransport in das Wärmespeichermedium und aus dem Wärmespeichermedium statt. Als Beispiel für einen derartigen Wärmespeicher sei hier der „PowerTank" der Firma PowerTank GmbH in 96515 Sonneberg genannt.Today's latent heat storage in the field of thermal solar energy use consist of containers in which is a heat storage medium such as. Paraffin located. Located inside these containers heat exchanger, the one with the heat storage medium stay in contact. Through this heat exchanger finds the heat transfer into the heat storage medium and from the heat storage medium instead of. As an example of such a heat storage here is the "PowerTank" from the company PowerTank GmbH in 96515 Sonneberg.

ProblemlösungTroubleshooting
Die im Schutzanspruch 1. und 2. genannte Erfindung löst das Problem üblicher Latentwärmespeicher. Mit der Erfindung wird die Bauweise von Latentwärmespeichern, erheblich vereinfacht und eine Verdrängung von Paraffin durch Gase, die aus dem Wärmeträger ausfallen, wird ausgeschlossen. Zudem sind keine Wärmetauscher in jedem einzelnen Latentwärmespeichermodul nötig. Dadurch werden der Montage- und Materialaufwand erheblich verringert.The invention mentioned in the protection claims 1 and 2 solve that Problem more common Latent heat storage. With the invention, the construction of latent heat storage is significantly simplified and a repression Paraffin from gases that precipitate from the heat transfer medium is excluded. moreover are not heat exchangers in every single latent heat storage module necessary. As a result, the assembly and material costs are significantly reduced.
Das Ausführungsbeispiel der Erfindung wird in Zeichnung 1. und 2. erläutert.The embodiment of the invention is explained in drawings 1. and 2.

Der Latentwärmespeicher besteht aus einem Rohr
(
Das Rohr des Latentwärmespeichermoduls muss so weit über die Flüssigkeitsoberfläche des Wärmeträgermediums hinausragen, dass das Wärmespeichermedium nicht am oberen Ende des Latentwärmespeichermoduls überläuft. Ist das Wärmespeicher medium flüssig, so steigen Gasblasen, die sich unterhalb des Wärmespeichermediums gesammelt haben durch den Innenraum des Latentwärmespeichermoduls auf. Kondensiertes Wärmeträgermedium dass sich auf dem Wärmespeichermedium im oberen Ende des Latentwärmespeichers befindet, kann durch das flüssige Wärmespeichermedium nach unten sinken. Um dem Wärmespeichermedium seine Wärme zu entziehen, wird die Temperatur des Wärmeträgermediums unter die Temperatur des Wärmespeichermediums gesenkt. Dadurch entsteht ein Wärmestrom aus dem Wärmespeichermedium in das Wärmeträgermedium. Sinkt die Temperatur des Wärmespeichermediums unter seine Schmelztemperatur, so beginnt es an der Wand des Latentwärmespeichermoduls zu erstarren. Dabei verringert das Wärmespeichermedium sein Volumen. Diese Volumenänderung des Wärmespeichermediums wird durch einströmendes Wärmeträgermedium am unteren Ende des Latentwärmespeichermoduls und durch einströmende Luft am oberen Ende des Latentwärmespeichermoduls ausgeglichen.The tube of the latent heat storage module must protrude so far beyond the liquid surface of the heat transfer medium that the heat storage medium does not overflow at the upper end of the latent heat storage module. If the heat storage medium is liquid, gas bubbles that have collected below the heat storage medium rise through the interior of the latent heat storage module. Condensed heat transfer medium that is located on the heat storage medium in the upper end of the latent heat storage medium can sink downward through the liquid heat storage medium. In order to extract its heat from the heat storage medium, the temperature of the heat transfer medium is lowered below the temperature of the heat storage medium. This creates a heat flow from the heat storage medium into the heat transfer medium. If the temperature of the heat storage medium drops below its melting temperature, it begins on the wall of the latent heat solidify memory module. The heat storage medium reduces its volume. This change in volume of the heat storage medium is compensated for by the inflowing heat transfer medium at the lower end of the latent heat storage module and by inflowing air at the upper end of the latent heat storage module.
