Description
Die Erfindung betrifft ein Warmwasserbereitungssystem für Trinkwasser.The invention relates to a water heating system for drinking water.
Bei herkömmlichen Pufferspeichern, die durch einen Wärmeerzeuger, vorzugsweise einen Heizkessel, mit Warmwasser beladen werden, wird durch die gewählte Art der Anordnung der Heizfläche im Speicher sowie durch die Einbindung der Zirkulationsleitung direkt in den Speicher und die damit verbundene Nachwärmung des Zirkulationswassers im Speicher selbst die Temperaturschichtung im Speicher während des Betriebs erheblich gestört. Die Störung der Schichtung führt dazu, dass die Speicher nur unvollkommen entladen werden können.With conventional buffer storage tanks, which are loaded with hot water by a heat generator, preferably a boiler, the selected type of arrangement of the heating surface in the storage tank and the integration of the circulation line directly into the storage tank and the associated post-heating of the circulation water in the storage tank itself Temperature stratification in the storage tank significantly disturbed during operation. The disturbance in stratification means that the storage tanks can only be partially discharged.
Dieses Problem wird gemäß dem der deutschen Gebrauchsmuster
In der
Die
Schließlich beschreibt die
Daraus ergibt sich als Aufgabe der Erfindung, Warmwasserbereitungssysteme nach dem Durchfluss-Gegenstrom-Prinzip dahingehend zu verbessern, dass auch höchste Zirkulationsverluste ohne Störung der Schichtung im Speicher abgedeckt werden.The object of the invention is therefore to improve hot water preparation systems based on the through-flow countercurrent principle in such a way that even the highest circulation losses are covered without disturbing the stratification in the storage tank.
Die Aufgabe wird erfindungsgemäß durch zwei alternative Warmwasserbereitungssysteme mit den Merkmalen des Schutzanspruchs 1 und des Schutzanspruchs 3 gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen erfährt die Erfindung in Form der Merkmale der Unteransprüche.The object is achieved according to the invention by two alternative water heating systems with the features of
Das Warmwasserbereitungssystem arbeitet im Durchfluss-Gegenstrom-Prinzip. Es besteht aus einem Pufferspeicher, der durch eine Wärmezentrale über eine Vorlaufleitung aufladbar ist, Rücklaufanschluss und Messfühlern, einer Trinkwasserleitung in Form einer gewendelten rohrförmigen Wärmetauscherfläche aus gegen Wasser korrosionsbeständigem Material, die in einer temperatur- und druckbeständigen Strömungszone angeordnet ist, die in den unteren Bereich des Pufferspeichers in Form eines offenen Strömungsspalts mündet, einer Zirkulationsleitung, die in die Trinkwasserleitung einmündet, und einer über die Trinkwasser Austrittstemperatur geregelten Umwälzpumpe. Die Strömungszone endet in beiden alternativen Ausführungen des Warmwassersystems im oberen Bereich des Pufferspeichers in einem Abstand vor dem Austritt der Trinkwasserleitung aus dem Pufferspeicher.The water heating system works on the flow countercurrent principle. It consists of a buffer storage tank that can be charged by a heating center via a flow line, return flow connection and sensors, and a drinking water line in the form of a coiled tubular heat exchanger surface made of material resistant to water corrosion, placed in a temperature and pressure-resistant flow zone, which opens into the lower part of the buffer tank in the form of an open flow gap, a circulation line, which opens into the drinking water line, and one over the Drinking water outlet temperature controlled circulation pump. In both alternative versions of the hot water system, the flow zone ends in the upper area of the buffer storage tank at a distance before the drinking water pipe exits from the buffer storage tank.
In der Ausführung gemäß Anspruch 1 weist die Strömungszone an ihrem oberen Ende einen Pufferwassereintritt sowie einen Pufferwasseraustritt im unteren Bereich des Pufferspeichers auf.In the embodiment according to
Eine Ausführung der Strömungszone ergibt sich bei dieser Variante, indem sie als glattes, gesicktes, gewelltes oder geripptes Strömungsrohr ausgebildet ist und insbesondere, indem das Strömungsrohr aus einem Plastwerkstoff besteht.An embodiment of the flow zone results from this variant in that it is designed as a smooth, beaded, corrugated or ribbed flow tube and in particular in that the flow tube consists of a plastic material.
Die alternative Ausführung der Strömungszone gemäß Anspruch 3 besteht darin, dass der ringförmige Außenbereich eines konzentrischen Doppelrohrs die Strömungszone bildet und der zylinderförmige Zentralbereich des konzentrischen Doppelrohrs wenigstens ein Teilvolumen des Pufferspeichers darstellt. Der zylindrische Zentralbereich des konzentrischen Doppelrohrs ist auch Teil der Schichtladezone des Pufferspeichers, indem der zylindrische Zentralbereich des konzentrischen Doppelrohrs mit dem zwischen der Außenwandung des konzentrischen Doppelrohrs und der Wandung des Pufferspeichers befindlichen Bereich der Schichtladezone kommunizierend verbunden ist.The alternative embodiment of the flow zone according to claim 3 is that the annular outer area of a concentric double tube forms the flow zone and the cylindrical central area of the concentric double tube represents at least a partial volume of the buffer storage. The cylindrical central portion of the double concentric duct is also part of the stratification zone of the buffer tank by communicating the central cylindrical portion of the double concentric duct with the stratified loading zone section located between the outer wall of the double concentric duct and the wall of the buffer tank.
Eine vorteilhafte Ausbildung beider Varianten des erfindungsgemäßen Warmwasserbereitungssystems besteht darin, dass eine Umwälzpumpe mit einem Ansaug im oberen Bereich des Pufferspeichers und einem Ausgang im oberen Bereich der Strömungszone ausgestattet, wobei der Ausgang der Umwälzpumpe vorzugsweise am oberen Ende der Strömungszone mündet.An advantageous embodiment of both variants of the water heating system according to the invention is that a circulating pump is equipped with an intake in the upper area of the buffer storage tank and an outlet in the upper area of the flow zone, with the outlet of the circulating pump preferably opening out at the upper end of the flow zone.
Die Zirkulationsleitung ist in beiden Varianten vorteilhaft aus einem für Trinkwasser zugelassenen Plastwerkstoff hergestellt, die Trinkwasserleitung in Form des gewendelten Wärmetauschers jedoch vorzugsweise aus hochlegierten Edelstahl. Die Trinkwasserleitung kann zur Vergrößerung der Oberfläche gesickt, gewellt oder gerippt sein.In both variants, the circulation line is advantageously made of a plastic material approved for drinking water, but the drinking water line in the form of the coiled heat exchanger is preferably made of high-alloy stainless steel. The drinking water pipe can be corrugated, corrugated or ribbed to increase the surface area.
