Description
Die Erfindung betrifft einen Hybridwärmespeicher, bestehend aus einen Latentwärmespeicher, eingebettet in einen Wärmespeicher gefüllt mit Wasser.The Invention relates to a hybrid heat storage, consisting of a latent heat storage, embedded in a heat storage filled with water.
Verschiedene Wärmetauscher befindlich im Wärmespeicher gefüllt mit Wasser, geben oder entnehmen Wärmeenergie für verschiedene Wärmeenergiesysteme, wie zum Beispiel Solarkreislauf, Heizungskreislauf, Warmwasser und Nachheizung.Various heat exchangers located in the heat storage filled with water, give or take heat energy for different Thermal energy systems such as solar circuit, heating circuit, hot water and Reheating.
Bei Latentwärmespeichern werden PCM (Phase Change Materials) eingesetzt, es sind Stoffe, die beim Schmelzen sehr viel Wärmeenergie aufnehmen und diese umgekehrt beim Erstarren wieder freisetzen.at Latent heat storage PCM (Phase Change Materials) are used, they are substances that when melting a lot of heat energy record and release the other way around when solidifying.
Derartige Materialien sind dem Fachmann bekannt und werden daher an dieser Stelle nicht näher erläutert.such Materials are known in the art and are therefore at this Do not move closer explained.
Wärmespeicher üblicher Bauart weisen einen Behälter gefüllt mit Wasser auf, sie besitzen eine Isolierung, um gespeicherte Wärmeenergie im Speicher zu halten und werden häufig zur Wärmespeicherung bei Heizungsanlagen zur Warmwasserversorgung oder zur Nutzung von Prozesswärme eingesetzt.Heat storage more usual Type have a container filled with water on, they have insulation to store stored heat energy in storage and are often used for heat storage in heating systems used for hot water supply or for the use of process heat.
Um den Wärmeträger für den Energietransport zum/vom Wärmespeicher z.B. Trinkwasser, Heizungswasser, Solarflüssigkeit und Wärmeträgeröl, nicht direkt miteinander zu verbinden, werden häufig Wärmetauscher eingesetzt, sie befinden sich innerhalb oder außerhalb des Speichers.Around the heat carrier for the energy transport to / from the heat storage e.g. Drinking water, heating water, solar fluid and thermal oil, not To connect directly to each other, heat exchangers are often used, they are inside or outside of the memory.
Modifizierte Wärmespeicher für spezielle Bereiche wie zum Beispiel Solaranlagen oder Holzkessel werden auch Pufferspeicher, Schichtenspeicher, Duospeicher oder auch Kombispeicher genannt, sie sind meistens mit Wasser gefüllt, weil Wasser eine hohe spezifische Wärmekapazität hat und durch seine niedrige Viskosität ein hervorragendes Wärmeträgermedium ist.modified heat storage for special Areas such as solar panels or wood-fired boilers will also be Buffer storage, stratified storage, duo storage or combi storage called, they are mostly filled with water, because water is a high has specific heat capacity and by its low viscosity an excellent heat transfer medium is.
Nachteilig hierbei ist, dass die Speicher gefüllt mit Wasser eine niedrige Energiedichte haben, dadurch sind diese Wärmespeicher sehr voluminös und können nur in sehr kleinen Baugrößen in Gebäuden wie Einfamilienhäuser, Altbauten oder Neubauten ohne Keller eingesetzt werden, weiterhin ist auch nachteilig, dass der Aufbau von Anlagen mit einem größeren Speichervolumen, meistens durch mehrere Einzelspeicher realisiert wird, wodurch sich ein großer Installationsaufwand ergibt.adversely Here is that the store filled with water is a low Energy density, therefore, these heat storage are very bulky and can only in very small sizes in buildings like Family houses, Old buildings or new buildings without basements are used, continue is also disadvantageous that the construction of plants with a larger storage volume, is usually realized by a plurality of individual memories, which is a large Installation costs results.
Eingesetzt werden zur Speicherung von Wärmeenergie auch Latentwärmespeicher, zum Beispiel gefüllt mit PCM (Phase Change Materials), sie haben den Vorteil große Wärmemengen auf kleinstem Raum zu speichern, nachteilig hierbei ist, dass die gespeicherte Wärmeenergie bei Bedarf nur sehr langsam abgegeben werden kann.used are used to store heat energy also latent heat storage, filled for example with PCM (Phase Change Materials), they have the advantage of large amounts of heat to save in the smallest space, disadvantageous here is that the stored heat energy If necessary, can be delivered only very slowly.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Hybridwärmespeicher der gattungsgemäßen Art zu schaffen, der einmal die Vorteile des Wärmespeichers, gefüllt mit Wasser, zum anderen die Vorteile des Latentwärmespeichers hat.Of the present invention is based on the object, a hybrid heat storage of the generic type to create, once the advantages of the heat storage, filled with Water, on the other hand has the advantages of latent heat storage.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in einem Wärmespeicher, gefüllt mit Wasser, sich ein oder mehrere Speicherpatronen gefüllt mit PCM (Phase Change Materials), befinden, weiterhin sind im Wärmespeicher, gefüllt mit Wasser, verschiedene Wärmetauscher zur hydraulischen Anbindung an verschiedene Wärmeenergiesysteme, wobei diese Wärmetauscher zum Beispiel an Solarkreisläufe, Erdwärmekreisläufe, Warmwasserversorgung, Nachheizkreisläufe, Prozesswärmekreisläufe und Heizungskreisläufe angeschlossen sein können, sie sind untereinander hydraulisch getrennt, weil oftmals verschiedene Wärmeträger verwendet werden und häufig auch unterschiedliche Leitungsdrücke herrschen.These Task is inventively characterized solved, that in a heat storage, filled with Water, one or more storage cartridges filled with PCM (Phase Change Materials), are still in heat storage, filled with water, different heat exchangers for hydraulic connection to various thermal energy systems, these heat exchangers for example to solar circuits, Geothermal circuits, hot water supply, Nachheizkreisläufe, Process heat cycles and Heating circuits you can be connected are hydraulically separated from each other, because often different Used heat transfer medium be and often also different line pressures prevail.
Durch die vorliegende Erfindung wird ein großes Wärmespeichervolumen für verschiedene Systeme, wie sie in ökologisch gebauten Häusern häufig vorkommen, auf kleinstem Raum bereitgestellt, und durch die meist begrenzten Platzverhältnisse in diesen Häusern ist der kompakte Aufbau des Hybridwärmespeichers besonders vorteilhaft.By The present invention will provide a large heat storage volume for various Systems as they are in ecological built houses happens often, provided in the smallest space, and by the most limited space in these houses the compact design of the hybrid heat storage is particularly advantageous.
Ein großes Wärmespeichervolumen bedeutet, dass lange Zeit Wärme bereitgestellt wird, ohne dass auf herkömmliche Art nachgeheizt werden muss, und viel Primärenergie kann dadurch eingespart werden.One great Heat storage capacity means that long time heat is provided without having to reheat in a conventional manner, and a lot of primary energy can be saved.
In einer bevorzugten Ausführungsform der Erfindung sind die Anschlüsse der Wärmetauscher nach außen geführt.In a preferred embodiment The invention relates to the connections the heat exchanger after Outside guided.
Vom besonderen Vorteil hierbei ist, den Wärmespeicher, gefüllt mit Wasser, nach außen hin zu isolieren.from particular advantage here is the heat storage, filled with Water, to the outside to isolate.
Durch die Erfindung ist es möglich, einmal Wärmeenergie über Wärmetauscher befindlich im Wasser schnell aufzunehmen und auch abzugeben, durch die Einbettung von Speicherpatronen gefüllt mit PCM (Phase Change Materials) im Wasser ist es möglich, viel Wärmeenergie kontinuierlich zwischen Wasser und den PCM-Speicherpatronen auszutauschen.By the invention it is possible once heat energy through heat exchangers to be quickly absorbed in the water and also to be released by embedding storage cartridges filled with PCM (Phase Change Materials) in the water it is possible a lot of heat energy continuously exchange between water and the PCM storage cartridges.
Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche.Further features of the invention are Ge Subject of the dependent claims.
