Description
Die Erfindung betrifft ein Warmwasserbereitungssystem für Trinkwasser.The 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. Dieses Problem
wird gemäß dem deutschen Gebrauchsmuster
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.from that arises as an object of the invention, water heating systems according to the flow-countercurrent principle to improve to that also highest circulation losses without disturbance the stratification will be covered in memory.
Die Aufgabe wird erfindungsgemäß durch ein Warmwasserbereitungssystem mit den Merkmalen des Schutzanspruchs 1 gelöst. 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 gewendelte rohrförmige Wärmetauscherfläche einmündet, und einer über die Trinkwasser-Austrittstemperatur geregelten Umwälzpumpe mit einem Ansaug im oberen Bereich des Pufferspeichers und einem Ausgang im oberen Bereich der Strömungszone. Die Strömungszone endet im oberen Bereich des Pufferspeichers in einem Abstand vor dem Austritt der Trinkwasserleitung aus dem Pufferspeicher. Vorteilhafte Weiterbildungen und Ausgestaltungen erfährt die Erfindung in Form der Merkmale der Unteransprüche. Eine vorteilhafte Ausbildung des erfindungsgemäßen Warmwasserbereitungssystems besteht darin, dass der Ausgang der Umwälzpumpe am oberen Ende der Strömungszone mündet. Eine erste vorteilhafte Ausführung der Strömungszone ergibt sich, indem sie als glattes, gesicktes, gewelltes oder geripptes Strömungsrohr ausgebildet ist und insbesondere, indem das Strömungsrohr aus einem Plastwerkstoff besteht. Eine weitere vorteilhafte Ausführung der Strömungszone 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. Die Zirkulationsleitung ist vorteilhaft aus einem für Trinkwasser zugelassenen Plastwerkstoff hergestellt, der gewendelte Wärmetauscher jedoch vorzugsweise aus hochlegierten Edelstahl. Der Wärmetauscher kann zur Vergrößerung der Oberfläche gesickt, gewellt oder gerippt sein.The Object is achieved by a water heating system solved with the features of the protection claim 1. The water heating system works in the flow-countercurrent principle. It consists of one Buffer storage through a heat center over a supply line is chargeable, return port and Sensors, a drinking water pipe in the form of a coiled tubular heat exchanger surface against water corrosion resistant material, which in one temperature and pressure resistant flow zone arranged in the lower area of the buffer in Form of an open flow gap opens, a Circulation line, which is in the coiled tubular Heat exchanger surface opens, and one over the drinking water outlet temperature controlled circulating pump with a suction in the upper area of the buffer tank and a Exit in the upper part of the flow zone. The flow zone ends at the top of the buffer at a distance before the outlet of the drinking water line from the buffer memory. advantageous Further developments and embodiments learn the invention in the form of the features of the subclaims. An advantageous Formation of the hot water preparation system according to the invention is that the output of the circulation pump at the top End of the flow zone opens. A first advantageous Execution of the flow zone results by as a smooth, beaded, corrugated or ribbed flow tube is formed and in particular, by the flow tube made of a plastic material. Another advantageous embodiment the flow zone is that the annular Outside of a concentric double tube, the flow zone forms and the cylindrical central area of the concentric Double tube represents at least a partial volume of the buffer memory. The circulation line is advantageous from one for drinking water approved plastic material, the coiled heat exchanger but preferably made of high-alloy stainless steel. The heat exchanger can increase the surface area be sickened, wavy or ribbed.
