Description

Vorrichtung zum Verhindern des inneren Wasserumlaufes in Warmwasserleitungen In Warmwasserversorgungsanlagen, die durch einen tiefstehenden Behälter gespeist werden, tritt in den Steigrohren, besonders wenn sie große Durchmesser haben, ein innerer Wasserumlauf ein. Dieser rührt daher, daß das an den Außenwänden sich abkühlende Wasser schwerer ist als das Warmwasser. im Innern der Rohrleitung. Infolgedessen fällt das abgekühlte Wasser nach unten und in den Kessel zurück, aus dem warmes Wasser wieder nach oben steigt. Dieser Umlauf tritt auch auf, wenn in die Steigleitung waagerechte oder vom Speicherkessel aus geneigt ansteigende Rohrstücke eingeschaltet sind. Infolge dieses inneren Umlaufes tritt aus dem tiefstehenden Warmwasserspeicher immer wieder frisches Warmwasser in die Leitung ein und kühlt sich dort ab, wodurch dauernde Wärmeverluste entstehen.Device to prevent the internal water circulation in hot water pipes In hot water supply systems that are fed through a deep tank occurs in the risers, especially if they are of large diameter internal water circulation. This is due to the fact that the cooling on the outer walls Water is heavier than hot water. inside the pipeline. Consequently the cooled water falls down and back into the boiler, from the warm Water rises up again. This circulation also occurs when in the riser horizontal pipe sections or pipe sections that rise at an incline from the storage tank are switched on are. As a result of this internal circulation, the low-lying hot water tank emerges again and again fresh hot water in the line and cools down there, which permanent heat losses occur.

Die Erfindung besteht in einer Vorrichtung, die dieses Umlaufen, insbesondere bei elektrisch beheizten Warmwasserspeichern, verhindern soll. Sie besteht darin, daß an einer oder mehreren Stellen der Warmwasserleitung Rohrschleifen eingebaut sind, in denen das Wasser beim Vorlaufen vom Warmwasserspeicher zu den Zapfstellen streckenweise nach unten fließen muß. In diesen Rohrschleifen müßte das an der Rohrwandung abgekühlte Wasser, um in den Warmwasserspeicher zurückzugelangen, streckenweise von unten nach oben fließen. Da dies aber nicht möglich ist, ist an diesen Stellen der Umlauf unterbrochen. Das Wasser in den Rohren kühlt sich also allmählich ab, dem Speicherinhalt wird aber nicht dauernd Wärme entzogen.The invention consists in a device that this revolving, in particular in the case of electrically heated hot water storage tanks. It consists in that pipe loops are installed at one or more points in the hot water pipe in which the water flows from the hot water tank to the taps must flow downwards in parts. In these pipe loops this would have to be on the pipe wall Cooled water to get back into the hot water tank in parts flow from the bottom up. Since this is not possible, is at these points the circulation is interrupted. So the water in the pipes gradually cools down, however, heat is not continuously withdrawn from the contents of the storage tank.

Die Abbildung zeigt zwei Einbaumöglichkeiten der Rohrschleifen. a ist der Warmwasserspeicher, b die nach oben führende Steigleitung. In diese ist die Rohrschleife c eingeschaltet, in der das den Zapfstellen zufließende Wasser streckenweise nach unten fließen muß. Diese Rohrschleife hindert das an den Rohrwandungen abgekühlte Wasser, in den Warmwasserspeicher zurückzutreten. Eine zweite Rohrschleife d, die am Übergang von einem waagerechten zu einem senkrechten Leitungsstück eingebaut ist, erfüllt denselben Zweck.The illustration shows two installation options for the pipe loops. a is the hot water storage tank, b is the ascending pipe leading upwards. In this is the pipe loop c switched on, in which the water flowing to the taps must flow downwards in parts. This pipe loop prevents this from happening on the pipe walls cooled water to withdraw into the hot water tank. A second pipe loop d, which are installed at the transition from a horizontal to a vertical piece of pipe serves the same purpose.
