Abstract

A latent heat storage element consists of a closed container capable of expansion and containing the latent heat storage material. The increased storage capacity of this element consists in the utilisation of the melting point of the latent heat material, which means: for each temperature level use is made of a different latent heat storage material. The supply and removal of heat is performed by means of the fluid medium surrounding the latent heat storage element. A store consists of many of these latent heat storage elements, which are stacked in a tank and surrounded by a fluid medium. This invention can be applied wherever heat is to be stored in large amounts and in small containers, in order to keep it at a constant temperature and to extract it once again at a different time. <IMAGE>

Latent heat storage elements

Beschreibung:Description:

Die Erfindung betrifft Latentwärmespeicher zum Zwecke der Speicherung von Wärme aufgrund von ab- bzw. aufgenommener Wärme beim Phasenwechsel eines Latentwärmespeichermaterials.The invention relates to latent heat storage for the purpose of storing heat due to the absorbed or absorbed Heat during the phase change of a latent heat storage material.

Bei Speicherung von Wärme in Tanks z.B. bei Solaranlagen wird z.Zt. die Temperatur des Wassers in diesem Tank erhöht um diese Wärmemenge bei Bedarf wieder herausziehen zu können.-Der Wärmeinhalt solcher Tanks ist gering, da nur 1 kcal pro Liter und aufgeheiztem Temperaturgrad vom Wasser· aufgenommen werden kann.When storing heat in tanks, e.g. in solar systems is currently the temperature of the water in this tank increases in order to be able to pull this amount of heat out again if necessary The heat content of such tanks is low, as only 1 kcal per liter and heated temperature level is absorbed by the water can be.

Bei den bisher auf dem Markt befindlichen Latentwärmespeichern ist der Nachteil, daß aufwendige Konstruktionen notwendig sind um die Wärme in und aus dem Speicher zu transportieren. Außerdem müssen Vorrichtungen vorgesehen werden um genügend Kristallisationspunkte beim Übergang von flüssig in fest zu haben, damit keine Unterkühlung auftritt. Aus diesen Gründen werden Latentwärmespeicher nur in relativ kleinen Einheiten gebaut.The latent heat accumulators currently on the market have the disadvantage that complex constructions are necessary are to transport the heat in and out of the storage tank. In addition, devices must be provided to ensure sufficient To have crystallization points at the transition from liquid to solid so that no hypothermia occurs. For these reasons Latent heat storage systems are only built in relatively small units.

Bei dem erfindungsgemäß beschriebenen Latentwärmespeicher werden diese Nachteile dadurch aufgehoben, indem die Einzelelemente jeweils für sich eine geschlossene Einheit bilden und in einem normalen Wassertank geschichtet werden können.In the latent heat storage device described according to the invention these disadvantages are eliminated by the fact that the individual elements each form a closed unit and can be layered in a normal water tank.

Durch die Größe (Kleinheit) der Einzelelemente sind in jedem genügend Kristallisationspunkte vorhanden um eine Unterkühlung zu verhindern. Der Wärmeinhalt des Wärmespeichers wird hauptsächlich durch den Wärmeinhalt der Einzelelemente sowie deren Anzahl bestimmt.Due to the size (smallness) of the individual elements are in each there are enough crystallization points to prevent hypothermia. The heat content of the heat storage is mainly determined by the heat content of the individual elements and their number.

Mit den erfindungsgemäß beschriebenen Latentwärmespeicherelementen kann durch Nachrüsten von normalen Wärmespeicher-Tanks oder -Kesseln die Speicherkapazität erhöht werden ohne die Anlage ändern zu müssen, da das Wärmetransportmedium als solches erhalten bleibt und nur die Latentwärmespeicherelemente im Tank oder Kessel umspült.With the latent heat storage elements described according to the invention, normal heat storage tanks can be retrofitted or boilers, the storage capacity can be increased without having to change the system, since the heat transport medium as such remains and only the latent heat storage elements in the tank or boiler washes around.
