Abstract

In the invention, instead of the parallel pipe, one pipe is guided within the supply line. As a result, the installation costs are lowered and an essential reduction in heat losses is achieved.

Brauchwasserzirkulationssystem für Brauchwasserversorgungsanlagen Domestic water circulation system for domestic water supply systems

Die Erfindung betrifft ein Brauchwasserzirkulationssystem für Brauchwasserversorgungslanlagen. Die Aufgabe der Zirkulationsleitung besteht darin, während der Zapfpausen einen Kreislauf von Zapfwasser zwischen dem Brauchwassererwärmer und den Zapfstellen herzustellen, damit beim Zapfen möglichst sofort warmes Wasser zur Verfügung steht.The invention relates to a service water circulation system for service water supply systems. The task of the circulation line is to provide a circulation of tap water during the pauses in tapping between the domestic hot water heater and the draw-off points so that warm water is available as soon as possible when tapping.

Dies wird gegenwärtig so gelöst, daß die Zapfstelle über eine weitere Leitung mit dem Warmwassererzeuger verbunden ist und eine Pumpe laufend, bzw. zeitabhängig Wasser umwälzt. Diese Zirkulationsleitungen sind jedoch energievernichtend .This is currently solved in such a way that the tap is connected to the hot water generator via another line is and a pump circulates water continuously or time-dependent. However, these circulation lines are energy-destroying .

Die Erfindung besteht darin, anstelle der bisher angewandten Ringleitung eine "Rohr-in-Rohr"-Leitung zu verwenden. Dies hat folgende Vorteile:The invention consists in using a "pipe-in-pipe" line instead of the previously used ring line. This has the following advantages:

Die Oberfläche der Leitung reduziert sich, wodurch eine geringere Wärmeabgabe vorhanden ist. Da bei der Innenleitung der Innendruck gleich Außendruck ist, kann diese mit dünnster Wandstärke und damit sehr preiswert sein. Es ist nur eine Leitung zu verlegen, es ist nur eine Isolation anzubringen.The surface of the pipe is reduced, which means that less heat is emitted. As with the internal line the internal pressure is the same as the external pressure, this can be with the thinnest wall thickness and therefore very inexpensive. Only one line needs to be laid, only insulation needs to be installed.

In der Anlage befindet sich eine Zeichnung, worin die Erfindung anhand eines Ausführungsbeispieles dargestellt ist.In the system there is a drawing in which the invention is illustrated using an exemplary embodiment is.

Das dargestellte Ausführungsbeispiel zeigt einen Warmwassererzeuger (1), welcher über einen Wärmetauscher (2) aufgeheizt wird. Die Aufheizung des Warmwassererzeugers kann mit Strom, Öl oder Gas erfolgen und soll hier nicht näher erläutert werden.The illustrated embodiment shows a hot water generator (1), which is heated up via a heat exchanger (2). The heating of the hot water generator can be done with electricity, oil or gas and will not be explained in more detail here.

Wird der Warmwasserhahn (3) geöffnet, fließt über den Kaltwasserzufluß (4) kaltes Wasser in den Warmwassererzeuger nach.If the hot water tap (3) is opened, the cold water flows through (4) cold water in the hot water heater after.

In den Zapfpausen erfolgt eine Umwälzung innerhalb der Warmwasserzuleitung (5), durch die Umwälzungspumpe (6) über das Innenrohr (7) bis zur Zapfstelle (3).
Der Rücklauf erfolgt über die Warmwasserzuleitung (5).During the pauses in tapping, the hot water supply line (5) is circulated by the circulation pump (6) via the inner pipe (7) to the tapping point (3).
The return takes place via the hot water supply line (5).
