Abstract

The heat storage system for a heat pump operating at lower temp. uses a heat storage vessel containing a substance which melts at a given temp. The vessel has concrete sides and base with an insulating layer inside the bottom, over the top and outside the sides. Between the top and bottom insulating layers are stacks of metal plates shaped to form channels through which air can circulate. Heating elements are positioned outside the channels, between the plates, and embedded in the melting substance.

Latent - WärmespeieherLatent - heat store

Die Erfindung betrifft einen Latent-Wärmespeicher mit Schmelzwärmespeicherung, insbesondere zur Wärmespeicherung für Heizungsanlagen.The invention relates to a latent heat store with melt heat storage, in particular for heat storage for heating systems.

Der Zweck der Erfindung besteht darin, den wirtschaftlichen Einsatz von Latent-Wärmespeicher in Verbindung mit dem zunehmenden Einsatz von Wärmepumpen und der Entwicklung von Heizsystemen mit niedrigeren Heizmedientemperaturen zu verbessei-n. The purpose of the invention is the economical use of latent heat storage in connection with the to improve the increasing use of heat pumps and the development of heating systems with lower heating medium temperatures.

Die bekannten Latent-Wärmespeicher mit Schmelzwärme— speicherung arbeiten mit durchströmenden flüssigen Wärmeträgermedien. Sie sind für die zur Zeit bekannten Warmwasser- und Luftheizungen noch ungeeignet, weil die erforderlichen Temperaturen dieser Heizungssysteme über der Schmelztemperatur der Speichermasse liegen. Wegen dieser Nutzungseinschränkung hat es bisher keine erschöpfenden Entwxcklungsbemühungen gegeben.The known latent heat storage with melt heat storage work with flowing through liquid heat transfer media. They are still unsuitable for the currently known hot water and air heating systems because the required temperatures of these heating systems are above the melting temperature of the storage mass. Because of this usage restriction, no exhaustive development efforts have been made so far.

Der Erfindung liegt die Aufgabe zugrunde, Wärme in Form von Schmelzwärme so zu speichern, daß zur Vereinfachung und gloieinseitiger Einuatζerweiterung auch mit durchströmender Luft alternativ zu oder im Wechsel mit anderen Heizmedien be- und entladen werden kann.The invention is based on the object of storing heat in the form of heat of fusion so that for simplification and Gloie-one extension also with flowing through Air alternatively or alternately with other heating media and can be discharged.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Metallbleche als Wärmeaustauschflächen in der Form und Anordnung eingebaut werden, daß durch die zwischen diesen Flächen hindurchströmende Luft ausreichend Wärme zur Be- und Entladung an die Speichermasse übertragen wird.This object is achieved according to the invention in that metal sheets are used as heat exchange surfaces in terms of shape and arrangement be built in that the air flowing through between these surfaces has sufficient heat for loading and unloading is transferred to the storage mass.

Die Form und Anordnung der Metallbleche berücksichtigt einerseits zum Pullen der Speichermasse deren Schüttwinkel und andererseits die Bedingungen der Wärmeübertragung durch die Abstimmung der Übertragungsflächen mit dem Durchlüftungsquer schnitt.On the one hand, the shape and arrangement of the metal sheets take into account their angle of repose for pulling the storage mass and on the other hand the conditions of the heat transfer through the coordination of the transfer surfaces with the ventilation cross cut.

Mit der zusätzlichen Anordnung von Rohrregistern zum Transport von flüssigen Medien oder der Anordnung von Elektro-Heizstäben wird der Latent-Wärmespeicher unabhängig von den Heizmedien und mit möglichem Wechsel zwischen diesen verwendbar.With the additional arrangement of pipe registers for the transport of liquid media or the arrangement of electric heating rods the latent heat storage becomes independent of the Heating media and can be used with the option to switch between them.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß der Latent-Warmespeicher in einfacher und deshalb kostengünstiger Ausführung im Niedrigtemperaturbereich vielseitig verwendbar ist und wegen der Form und Anordnung seiner Metallbleche als Wärmeaustauschflächen mit relativ großer Speicherleistung wenig Stellfläche benötigt.The advantages achieved by the invention are in particular that the latent heat storage in simple and therefore more cost-effective execution in the low temperature range is versatile and because of the shape and arrangement its metal sheets as heat exchange surfaces with a relatively high storage capacity require little floor space.

Beim Betrieb von Luftheizungsanlagen kann er z. B. als Nachtspeicherheizung durch den Einbau von Elektroheizstäben während der Niedrigtarifzeit mit Hilfe von elektrischem Strom geladen und für den Heizbetrieb mit der druchströmenden Luft entladen werden.When operating air heating systems, he can z. B. as night storage heating through the installation of electric heating rods Charged with the help of electricity during the low tariff period and for heating with the air flowing through be discharged.

Beim Einsatz von Wärmepumpen z. B. mit Luft/Wasser-Betrieb kann er'bei eingebautem Rohrregister Überschußwärme vom wasserdurchflossenen Kondensator speichern und mit der durchströmenden Luft entladen werden, wobei die direkte Wärmeabgabe bei Luftheizungsbetrieb wie auch die indirekte Wärmeabgabe über den Verdampfer bei Warmwasserheizungsbetrieb möglich ist.When using heat pumps z. B. with air / water operation If the pipe register is installed, it can generate excess heat from the water flowing through it Store the condenser and discharge it with the air flowing through it, with the direct heat dissipation during air heating operation as well as indirect heat dissipation via the evaporator in hot water heating mode.
