Description
Die Erfindung bezieht sich auf einen Pufferspeicher mit darin aufgenommenem oder aufnehmbarem Wasser zum Speichern von über eine Aufwärmvorrichtung zugeführter Wärme. The invention relates to a buffer memory with water received or receivable therein for storing heat supplied via a warm-up device.
Derartige Pufferspeicher sind in verschiedenen Ausführungsformen bekannt, beispielsweise als Warmwasser-Schichtenspeicher, wie ihn die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Pufferspeicher der eingangs genannten Art bereitzustellen, mit dem anfallende Wärmemengen möglichst gut nutzbar sind. The present invention has for its object to provide a buffer memory of the type mentioned, with the accumulating amounts of heat are as good as possible.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Hierbei ist vorgesehen, dass in den Pufferspeicher, insbesondere mittels einer Tragevorrichtung, mit dem Wasser in Wärmeaustauschverbindung gebrachtes oder bringbares Phasenwechselmaterial eingebracht ist, welches ab einer vorgegebenen Schwellentemperatur des Wassers Wärme aufgrund eines Phasenwechsels speichert und unterhalb der Schwellentemperatur wieder an das Wasser abgibt. This object is achieved with the features of
Fällt z.B. von einem Ofen oder einer anderen Wärmequelle im Überfluss zugeführte Wärme an, so kann diese oberhalb einer charakteristischen Schwellentemperatur des Phasenwechselmaterials, die auf eine gewünschte Schwellentemperatur des Wassers in dem Pufferspeicher abgestimmt ist, bei relativ kleinem Volumen des Phasenwechselmaterials (PCM) effizient gespeichert werden. Sinkt die Wassertemperatur durch Wärmeentnahme bzw. durch Entnahme von warmem Wasser unter die Schwellentemperatur ab, so wird die latent in dem Phasenwechselmaterial gespeicherte Wärme durch den Rückübergang der Phase dem Wasser zugeführt, sodass dessen Temperatur möglichst lange hoch gehalten werden kann, selbst wenn von außen keine zusätzliche Wärme zugeführt wird. Das Phasenwechselmaterial ergibt die Möglichkeit, auch relativ kleine Wasserspeicher zu verwenden, die den Vorteil eines schnellen Aufwärmens von Wasser bieten. Falls e.g. Heat supplied in excess from an oven or other heat source may be efficiently stored above a characteristic threshold temperature of the phase change material that is tuned to a desired threshold temperature of the water in the buffer memory at relatively low volume of the phase change material (PCM). If the water temperature drops below the threshold temperature by removing heat or by removing warm water, the heat stored latently in the phase change material is supplied to the water through the return of the phase, so that its temperature can be kept high for as long as possible, even if no external heat is present additional heat is supplied. The phase change material gives the opportunity to use even relatively small water reservoirs, which offer the advantage of rapid warming up of water.
Verschiedene Ausführungsformen des Pufferspeichers bestehen darin, dass der Pufferspeicher zum Liefern von Heizungs- und / oder Trinkwasser ausgebildet ist. Hiervon hängt auch beispielsweise die Menge des Phasenwechselmaterials, dessen Schwellentemperatur und / oder die Art des Materials ab, welches entsprechend gewählt werden kann. Various embodiments of the buffer memory are that the buffer memory is designed to supply heating and / or drinking water. Of this, for example, the amount of the phase change material, its threshold temperature and / or the type of material depends, which can be selected accordingly.
Weitere vorteilhafte Ausgestaltungsmöglichkeiten bestehen darin, dass die Wärmespeicherkapazität des Phasenwechselmaterials auf das Wasservolumen hinsichtlich Menge, abzuführender Wärmemenge und / oder Wasserverbrauch abgestimmt ist, und weiterhin darin, dass auch die Wärmeaustauschgeschwindigkeit des Phasenwechselmaterials durch die Materialwahl auf das Wasservolumen und / oder die abzuführende Wärmemenge und / oder den Wasserverbrauch abgestimmt ist. Further advantageous design options are that the heat storage capacity of the phase change material is tuned to the volume of water in terms of amount, heat dissipation and / or water consumption, and further that also the heat exchange rate of the phase change material by the choice of material on the volume of water and / or the amount of heat dissipated and / / or the water consumption is matched.
Für den Aufbau, die Funktion und den Einsatz des Pufferspeichers sind ferner die Maßnahmen von Vorteil, dass das Phasenwechselmaterial über die Tragevorrichtung austauschbar in dem Pufferspeicher aufgenommen ist. Hierbei kann vorteilhaft vorgesehen sein, dass die Tragevorrichtung einen Nachfüllbehälter für das Phasenwechselmaterial aufweist. For the construction, the function and the use of the buffer memory, the measures are also advantageous in that the phase change material is exchangeably received in the buffer memory via the carrying device. In this case, it can be advantageously provided that the carrying device has a refill container for the phase change material.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. The invention will be explained in more detail with reference to an embodiment with reference to the drawing.
