Description

Die Latentwärmezellen werden aus einem Temperatur beständigem Material gefertigt. Sie bestehen aus wärmebeständigem Kunststoff oder Metall. Sie werden in allen Systemen eingesetzt, in denen Wärme oder Kälte gespeichert werden soll.The Latent heat cells become of a temperature resistant Material made. They are made of heat-resistant plastic or metal. They are used in all systems where heat or Stored cold shall be.

Die Form ist zylinderisch oder auch nach Anforderung mehreckig, die Höhen und Durchmesser sind variabel. Ein Boden verschließt den Körper nach unten, ein Deckel nach oben.The Shape is cylindrical or even polygonal upon request, the Heights and Diameters are variable. A bottom closes the body down, a lid up.

Das Innere dieser Körper besteht aus einem Hohlraum, der die jeweilige Art der Latentspeicher-masse aufnimmt – sogenannte PCM (Phase Change Materials) – sowie einen speziellen 3-dimensionalen Wärmetauscher aus hocheffizienten, wärmeleitenden Materialien, wie Kupfer, Aluminium, Graphit, oder Carbon. Der Wärmetauscher ist nach dem Prinzip eines sogenannten Gegenstromwärmetauscher gebaut. Das bedeutet, daß die Wärmetauscher thermisch miteinander verschweißt sind, jeweils Wärme oder Kälte, von einem Tauscher zum anderen Tauscher übertragen werden kann. Jeder Wärmetauscher hat seinen eigenen Vor- und Rücklauf.The Inside of these bodies consists of a cavity containing the particular type of latent storage mass absorbs - so-called PCM (Phase Change Materials) - as well a special 3-dimensional heat exchanger made of highly efficient, thermally conductive Materials such as copper, aluminum, graphite, or carbon. The heat exchanger is based on the principle of a so-called countercurrent heat exchanger built. This means that the heat exchangers thermally welded together are, each heat or cold, can be transferred from one exchanger to another exchanger. Every heat exchanger has its own forward and reverse.

Er dient dazu, die jeweiligen PCM's (Phase Change Materials) aufzuschmelzen, sie von einem festem in einen flüssigen Zustand, von einem flüssigen in einen festen Zustand, umzuwandeln. Durch die Wärmetauscher fließen dabei Wärmeträgerflüssigkeiten, oder auch Gase, die zur Wärme- oder Kälteerzeugung dienen.He serves to the respective PCM's (Phase Change Materials) melt them down from a solid in a liquid Condition, from a liquid into a solid state, to transform. Through the heat exchanger flow while heat transfer fluids, or gases that are used for heat or refrigeration serve.

Die zu speichernde Wärme- oder Kälteenergie, kann dabei aus allen technisch-physikalischen bekannten Wärme-Kälteerzeugern entnommen werden.The heat to be stored or cold energy, can be known from all technical-physical Heat and cold generators be removed.
