Description
Die Erfindung betrifft einen Pufferspeicher mit mindestens drei Pufferanschlüssen.The invention relates to a buffer memory having at least three buffer terminals.
In einem Pufferspeicher ist eine möglichst stabile Temperaturschichtung angestrebt. Die Entnahme und Zuführung von Flüssigkeit kann zu unerwünscht starken Verwirbelungen führen, die die Schichtung negativ beeinflussen.In a buffer storage as stable as possible stratification of temperature is sought. The removal and supply of liquid can lead to undesirably strong turbulences, which adversely affect the stratification.
Es ist daher Aufgabe der Erfindung, einen Pufferspeicher zur Verfügung zu stellen, bei dem der Pufferspeicherinhalt in seiner Temperaturschichtung möglichst stabil gehalten wird.It is therefore an object of the invention to provide a buffer memory available in which the buffer memory content is kept as stable as possible in its temperature stratification.
Diese Aufgabe wird bei einem Pufferspeicher der eingangs genannten Art dadurch gelöst, dass die Pufferanschlüsse in das Pufferspeicherinnere geführt werden und in einer horizontal ausgerichteten Tellerscheibe münden.This object is achieved in a buffer memory of the type mentioned above in that the buffer connections are guided into the buffer memory inside and open into a horizontally aligned dish disk.
Die Tellerscheibe besteht aus zwei parallelen Platten, die durch geeignete Abstandhalter einen Abstand h zueinander aufweisen. Der jeweilige Pufferanschluss mündet möglichst zentral in einer der Platten, die im Folgenden der Einfachheit halber Einspeiseplatte genannt wird. Trotz dieser Bezeichnung kann über die Tellerscheibe sowohl beladen als auch entladen werden. Die der Einspeiseplatte gegenüberliegende Platte wird im Folgenden Prallplatte genannt. Die Einspeiseplatte kann unterhalb oder oberhalb der Prallplatte angeordnet sein. Die Prallplatte weist vorzugsweise den gleichen Außendurchmesser auf wie die Einspeiseplatte.The dish washer consists of two parallel plates which have a distance h from each other by suitable spacers. The respective buffer connection opens as centrally as possible in one of the plates, which in the following is called feeder plate for the sake of simplicity. Despite this name can be both loaded and unloaded on the dish washer. The plate opposite the feed plate is called baffle plate in the following. The feed plate can be arranged below or above the baffle plate. The baffle plate preferably has the same outer diameter as the feed plate.
In den Pufferspeicher durch den jeweiligen Pufferanschluss hindurch einfließende Flüssigkeit prallt somit gegen die Prallplatte und wird seitlich abgeführt. Bei möglichst symmetrischer Anordnung, horizontaler Ausrichtung der Platten und vertikaler Ausrichtung des Endstückes des Pufferanschlusses wird das einströmende Wasser am Umfang der Tellerscheibe gleichmäßig austreten und hierdurch eine allenfalls geringe Verwirbelung der Flüssigkeit im Pufferspeicher bewirken.Liquid flowing into the buffer memory through the respective buffer connection thus bounces against the baffle plate and is discharged laterally. In the most symmetrical arrangement, horizontal alignment of the plates and vertical alignment of the end piece of the buffer connection, the inflowing water will emerge uniformly on the circumference of the disc and thereby cause at most a slight turbulence of the liquid in the buffer memory.
Die geringe Verwirbelung und damit stabile Temperaturschichtung kann – abgesehen von der damit verbundenen Eindämmung der unerwünschten Entropiezunahme – außerdem vorteilhaft für die Regelung sein. Falls z. B. ein Spitzenlastkessel angeschlossen ist, kann dieser direkt über am Pufferspeicher angeordnete Fühler, z. B. Speicherfühler für Warmwasser und/oder Vorlauffühler für eine witterungsgeführte Heizung, geregelt werden. Eine Regelung unter Kopplung der Regelung anderer Wärmequellen ist dann nicht mehr erforderlich, was ebenfalls zur Energieeinsparung und zur Einsparung von Materialkosten beitragen kann.The low turbulence and thus stable temperature stratification can - apart from the associated containment of unwanted entropy increase - also be beneficial for the scheme. If z. B. a peak load boiler is connected, this can be directly via the sensor arranged on the buffer memory, z. As storage tank sensor for hot water and / or flow sensor for weather-compensated heating, are regulated. A regulation coupled with the regulation of other heat sources is then no longer necessary, which can also contribute to energy saving and saving on material costs.
Es hat sich als vorteilhaft erwiesen, den Abstand h zwischen den Platten so zu dimensionieren, dass er mindestens den zweifachen Innendurchmesser des in der Einspeiseplatte mündenden Pufferanschlussrohres und maximal den achtfachen Wert des Innendurchmessers dieses Pufferanschlussrohres beträgt.It has proved to be advantageous to dimension the distance h between the plates such that it is at least twice the inner diameter of the buffer connection pipe opening into the feed plate and at most eight times the inner diameter of this buffer connection tube.
Des Weiteren ist es vorteilhaft, wenn der Außendurchmesser der Tellerscheibe oder zumindest eine der beiden Platten der Tellerscheibe mindestens ein Drittel des Innendurchmessers des Pufferspeichers beträgt. Gleichzeitig soll der Außendurchmesser der Tellerscheibe oder zumindest einer der Platten der Tellerscheibe mindestens das Zehnfache des Innendurchmessers des zugehörigen Pufferanschlussrohres betragen.Furthermore, it is advantageous if the outside diameter of the dish washer or at least one of the two plates of the dish washer is at least one third of the inside diameter of the buffer memory. At the same time, the outside diameter of the dish washer or at least one of the plates of the dish washer should be at least ten times the inside diameter of the associated buffer connection tube.
Vorzugsweise wird jeder der Pufferanschlüsse mit einer Tellerscheibe versehen.Preferably, each of the buffer connections is provided with a dish washer.
Die Tellerscheibenanschlüsse können auch für Pufferspeicher mit mehr als drei Pufferanschlüssen, z. B. vier Pufferanschlüssen, vorgesehen werden.The Tellerscheibenanschlüsse can also for buffer memory with more than three buffer connections, z. B. four buffer terminals are provided.
Es ist vorteilhaft, einen mit horizontalen Tellerscheiben versehenen Pufferspeicher so zu betreiben, dass die Beladung und die Entladung des Pufferspeichers über einen gemeinsamen Pufferanschluss erfolgen. Der gemeinsame Pufferanschluss für Be- und Entladung kann auf mindestens einer Höhe, vorteilhaft an jedem der Pufferanschlüsse, vorgesehen werden. Durch die Be- und Entladung über einen gemeinsamen Pufferanschluss wird der Pufferspeicher nur mit dem Netto-Volumenstrom aus Belade- und Entladestrom durchsetzt. Der gemeinsame Pufferanschluss für Be- und Entladung trägt somit dazu bei, die Stabilität der Temperaturschichtung im Pufferspeicher möglichst gering zu beeinflussen.It is advantageous to operate a buffer storage provided with horizontal plate washers so that the loading and the discharge of the buffer storage take place via a common buffer connection. The common buffer port for loading and unloading may be provided at least one level, advantageously at each of the buffer ports. By loading and unloading via a common buffer connection, the buffer tank is only interspersed with the net volume flow from the loading and unloading flow. The common buffer connection for loading and unloading thus contributes to the lowest possible influence on the stability of the temperature stratification in the buffer memory.
