Abstract

Die Erfindung bezieht sich auf einen Wärmespeicher, bestehend aus einem mit einer Flüssigkeit, insbesondere Wasser, gefüllten Behälter und einem in der Flüssigkeit befindlichen Wärmetauscher, der vorzugsweise von Wasser durchflossen wird. Die Erfindung besteht darin, daß der Wärmetauscher in vertikaler Richtung verfahrbar ist und daß er sich bei Beladung des Speichers unter, insbesondere unmittelbar unter der Heiß-Flüssigkeitsschicht und bei Entladung in dieser Schicht, insbesondere in deren unterem Bereich, befindet.The invention relates to a heat accumulator, consisting of a container filled with a liquid, in particular water, and a heat exchanger located in the liquid, through which water preferably flows. The invention consists in the fact that the heat exchanger can be moved in the vertical direction and that it is located under, in particular directly under, the hot-liquid layer when the store is loaded and in this layer, in particular in its lower region, when it is discharged.

Description

Die Erfindung bezieht sich auf einen Wärmespeicher so nach dem Gattungsbegriff des Patentanspruchs 1.The invention relates to a heat accumulator according to the preamble of claim 1.

Der Erfindung iiegt die Aufgabe zugrunde, diesen Wärmespeicher derart auszubilden, daß der Wirkungsgrad sowohl beim Wärmespe'chern als auch beim Wärmeentnehmen verbessert wird.The invention is based on the object of designing this heat accumulator in such a way that the efficiency is improved both in the heat storage and in the removal of heat.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichnungsteil des Patentanspruchs 1 enthaltenen Merkmale gelöst.This object is achieved according to the invention by what is contained in the characterizing part of claim 1 Features solved.

Ein solcher Speicher ist beispielsweise in Heizungskreisläufen, die mit elektrischem Strom von Solarzellen oder Kraft- Wärmekopplungsaggregaten gespeist werden und Wärme über Heizkörper abgeben, anwendbar.Such a memory is, for example, in heating circuits that use electricity from solar cells or combined heat and power units are fed and emit heat via radiators, applicable.

In der nachfolgenden Beschreibung wird anhand der Zeichnug ein Ausführungsbeispiel der Erfindung beschrieben. In the following description, an embodiment of the invention is described with reference to the drawing.

In einem Behälter 1, der mit Wasser (Wasserspiegel 2) gefüllt ist, ist ein Wärmetauscher 3 über Spindeln 4 in vertikaler Richtung verfahrbar angeordnet. Zwei Verbindungsschlüuche 5, 6 sind für den Wassereinfluß und den Wasserausfluß vorgesehen. Ein Motor 7 dreht die Spindeln 4 über Spindeln 8 und bewirkt damit die Hin- und Herbewegung des Wärmetauschers 3. Die Steuerung des Wärmetauschers 3 erfolgt über in einer vertikalen Reihe am Behälter 1 des Speichers angeordnete Temperatur-Fühler 10.In a container 1 filled with water (water level 2) is filled, a heat exchanger 3 is arranged to be movable in the vertical direction via spindles 4. Two connection hoses 5, 6 are provided for the water inlet and the water outlet. A motor 7 rotates the Spindles 4 over spindles 8, thereby causing the heat exchanger 3 to move back and forth. The controller of the heat exchanger 3 takes place in a vertical Row of temperature sensors 10 arranged on container 1 of the storage tank.

Wahlweise ist im oberen. Bereich des Speichers ein zweiter Wärmetauscher 9 befestigt, über den warmes Brauchwasser abgenommen werden kann.Optional is in the upper. Area of the memory a second heat exchanger 9 is attached over the warm Domestic water can be removed.
