Abstract

The stratified warm water storage vessel has a heat exchanger with flow and return in a water reservoir. There is also a domestic supply flow and return. In the reservoir (4) of the boiler (1) are two horizontal perforated plates (5,6) to prevent disturbance to the temp strata by the circulation pump. Between the two plates (5,6) packs of bolts (7) are placed to increase the potential storage capacity. USE/ADVANTAGE - Stratified warm water storage vessel incorporates a simpler means of preventing disturbance than using separate vessels.

Description

Die Erfindung richtet sich auf einen Warmwasserschichten­ speicher mit einem Wasserreservoir und darin angeordnetem Wärmetauscher mit Heizwasservor- und Rücklauf sowie Brauch­ wasservor- und Rücklauf.The invention is directed to hot water stratification storage with a water reservoir and arranged therein Heat exchanger with heating water supply and return as well as custom water supply and return.

Derartige Schichtenspeicher sind bekannt, und zwar in un­ terschiedlichen Ausführungsformen. So beispielsweise aus dem DE-31 20 118.Such stratified memories are known, namely in un different embodiments. For example, from DE-31 20 118.

Bei derartigen Schichtspeicherboilern macht man sich in der Regel das Prinzip zunutze, daß Wasser in unterschiedli­ chen Temperaturen aufgrund unterschiedlicher Dichte in ei­ nem vertikalen Behälter in Temperaturschichtungen vor­ liegt. So kann beispielsweise über wärmere Bereiche eines derartigen Speichers kaltes Heizwasser vorgewärmt werden, kaltes Brauchwasser kann in gleicher Weise vorgewärmt wer­ den und heißes Brauchwasser kann entsprechend entnommen werden.With such stratified storage boilers one makes oneself in generally use the principle that water in different Chen temperatures due to different density in egg vertical container in temperature layers lies. For example, over warmer areas cold heating water of this type are preheated, cold process water can be preheated in the same way hot and hot water can be removed accordingly will.

Ein Problem derartiger Schichtspeicherboiler liegt darin, daß, um die Temperaturschichtungen nicht unnötig zu verwir­ beln, Gefäße eingebaut werden, die die entsprechenden Wär­ metauscher und Betriebswässer voneinander trennen durch so­ genannte Kessel im Kessel.One problem with such stratified storage boilers is that that in order not to unnecessarily confuse the temperature stratifications beln, vessels are installed, the appropriate heat Separate the exchanger and process water from each other in this way called boiler in the boiler.

Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der mit einfachen Mitteln sichergestellt wird, daß eine Zerstörung der Temperaturschichtungen innerhalb des Schich­ tenspeichers selbst bei laufender Umwälzpumpe verhindert oder weitestgehend unterbunden wird.The object of the invention is to provide a solution with who is ensured by simple means that a Destruction of the temperature layers within the layer prevents storage even when the circulation pump is running or is largely prevented.

Bei einem Warmwasserschichtenspeicher der eingangs bezeich­ neten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß im Wasserreservoir des Boilers zur Verhinde­ rung der Zerstörung der Temperaturschichtung bei laufender Umwälzpumpe wenigstens ein horizontal angeordnetes Loch­ blech vorgesehen ist.In the case of a hot water layer storage tank, which is referred to at the beginning Neten kind this object according to the invention solved that in the water reservoir of the boiler to prevent destruction of the temperature stratification while running Circulation pump at least one horizontally arranged hole sheet is provided.

Es hat sich gezeigt, daß das Vorsehen eines einfachen Loch­ bleches hier zu besonders guten Lösungen führt, das Loch­ blech verhindert eine zu starke Durchwirbelung der Tempera­ turschichtung bei laufender Umwälzpumpe. Die durch den Na­ turumlauf im Boiler selbst vorhandene Temperaturumschich­ tung soll und wird damit allerdings nicht unterbunden.It has been shown that the provision of a simple hole sheet here leads to particularly good solutions, the hole sheet prevents excessive swirling of the tempera door stratification with the circulation pump running. The through the na temperature circulation in the boiler itself However, this should not and will not prevent this.

In Ausgestaltung ist vorgesehen, daß im Warmwasserschich­ tenspeicher auf Abstand zueinander zwei Lochbleche im Boi­ lerreservoir vorgesehen sind.In an embodiment it is provided that in the hot water layer memory at a distance of two perforated plates in the boi Reservoir are provided.

Mit dieser Maßnahme wird zum einen ein zusätzlicher Schutz gegen eine Verwirbelung innerhalb des Boilers erreicht, zum anderen stellt die Schicht zwischen den beiden Lochble­ chen die Möglichkeit dar, zusätzliche Einbauten vorzuse­ hen, wie dies noch weiter unten beschrieben ist.This measure provides additional protection against swirling inside the boiler,  on the other hand, the layer between the two perforated sheets provide the opportunity to advance additional installations hen, as described below.

Die Erfindung sieht auch vor, daß die Lochbleche nur mit außenrandseitigen Löchern ausgerüstet sind. Messungen ha­ ben ergeben, daß auch eine solche Maßnahme zur Optimierung des gewünschten Erfolges beiträgt.The invention also provides that the perforated plates only with holes on the outer edge are equipped. Measurements ha ben show that such an optimization measure of the desired success.

Vorteilhaft kann es sein, wenn zwischen den beiden Lochble­ chen Fixiersalzpackungen zur Erhöhung der potentiellen Speicherfähigkeit vorgesehen sind. Das Vorsehen eines Fi­ xiersalzlagers optimiert die Ausbeute eines derartigen Boi­ lers insbesondere deswegen, weil man sich den Phasenwech­ sel des Fixiersalzes im Bereich von 50°C zunutze machen kann, der durch die Lösungsenergie vorhandene Wärmeinhalt kann hier voll genutzt werden. Natürlich können auch andere Salze als Wärmeträger eingesetzt werden.It can be advantageous if between the two perforated sheets Chen fixing salt packs to increase the potential Storage capacity is provided. The provision of a fi Xiersalzlagers optimizes the yield of such a boi It is especially because you look at the phase change Make use of sel of the fixing salt in the range of 50 ° C can, the heat content available through the solution energy can be fully used here. Of course you can too other salts can be used as heat transfer media.

Die Erfindung sieht auch vor, daß oberhalb und unterhalb des/der Lochbleche/s je ein Wärmeaustauscher im Schicht- Speicherboiler vorgesehen ist. Dies hat den Vorteil, daß ein derartiger Warmwasserschichtenspeicher auch etwa in Verbindung mit Solarheizelementen eingesetzt werden kann, um auch geringste Temperaturunterschiede noch innerhalb des Speichers auszunutzen. The invention also provides that above and below of the perforated plate / s, one heat exchanger each in the layer Storage boiler is provided. This has the advantage that such a hot water layer storage also in about Connection with solar heating elements can be used to keep even the smallest temperature differences within to use the memory.  

Eine besonders optimale Lösung derartiger im Warmwasser­ schichtenspeicher eingebauter Wärmetauscher besteht darin, daß wenigstens einer der Wärmetauscher als parallel verleg­ ter Doppelrohrwärmetauscher ausgebildet ist. Hier kann im gleichen Anbauvolumen eine praktisch doppelt so hohe Kapa­ zität des Wärmetauschers erreicht werden. Auch dient er zur optimalen Ausnutzung kleiner Temperaturdifferenzen.A particularly optimal solution of this kind in hot water Layered heat exchangers consist of that at least one of the heat exchangers is laid as parallel ter double tube heat exchanger is formed. Here in same cultivation volume a Kapa practically twice as high heat exchanger can be achieved. He also serves for optimal use of small temperature differences.
