Abstract

A hot water storage tank with layered effect, i.e. hot water layers at the top, has a heating system comprising one or more heat exchangers (2, 3) outside the tank supplied with cold water from the bottom tapping (12) via a pump (4) and ducted back into the wider bottom (13) of a tapering vertical duct (14) fitted to the inside of the tank. Hot water rises up the duct and out of the narrow top. To improve the layering effect several apertures (28) are provided in the sides of the duct. This allows heated water to be added to the appropriate layers without undue disturbance.

Description

Die Erfindung betrifft einen Warmwasserschichtspeicher gemäß dem Oberbegriff des Anspruchs 1. Ein solcher Warmwasserschichtspeicher ist durch die DE 102 37 771 bekannt. Dort ist das an die Speicherwand angebrachte Halbrohr 14 bis zur Oberkante der Leiteinrichtung 22 durchgehend geschlossen ausgebildet. Bei dieser Ausführung kann das aufströmende, warme Wasser nur an der Oberkante der Leiteinrichtung 22 ins Speicherinnere austreten, was nicht immer optimal ist.The invention relates to a hot-water layer memory according to the preamble of claim 1. Such a hot-water layer memory is through DE 102 37 771 known. There is the attached to the storage wall half pipe 14 to the top of the guide 22 formed completely closed. In this embodiment, the upflowing, warm water can only at the top of the guide 22 leak into memory, which is not always optimal.

Der Erfindung liegt die Aufgabe zugrunde, das Halbrohr 14 so auszubilden, dass bei bestimmten Temperaturverhältnissen eine verbesserte Schichtausbildung im Speichervolumen erfolgen kann.The invention is based on the object, the half pipe 14 in such a way that at certain temperature conditions improved layer formation can take place in the storage volume.

Diese Aufgabe wird durch den gekennzeichneten Teil des Anspruchs 1 gelöst. Erfindungsgemäß wird dabei vorgesehen, dass das Halbrohr 14 mindestens eine Austrittsöffnung seitlich in das Speichervolumen 1 aufweist. Der Vorteil dieser Anordnung liegt darin, dass eine optimalere Schichtausbildung erfolgen kann. Vorteilhaft ist dabei, dass etwa drei oder mehr Austrittsöffnungen vorgesehen werden können.This object is achieved by the marked part of claim 1. According to the invention it is provided that the half pipe 14 at least one outlet opening laterally into the storage volume 1 having. The advantage of this arrangement is that a more optimal layer formation can take place. It is advantageous that about three or more outlet openings can be provided.

Die Erfindung wird folgend an der einzigen Figur erläutert.The Invention will be explained below with reference to the single figure.

Entsprechend der Schutzansprüche 2 und 3 können weitere Leiteinrichtungen wie das im Schutzanspruch beschriebene Halbrohr ausgebildet sein.According to the protection claims 2 and 3 can be formed further guide devices such as the half pipe described in the protection claim.

Die Figur zeigt einen Speicherbehälter 1 in senkrechter Lage mit einer Höhe größer als sein Durchmesser und mit einer möglichen Anordnung der hydraulischen Komponenten: Wärmetauscher 2 und 3, Pumpen 4 und 8, Regler 5 und Ventile 6 und 7, einen Entlüfter 9, einen Heißwasser-Entnahmestutzen 11, einen Aufheiz-Entnahme- und Rückführstutzen 12, einen Zuführungsstutzen 13 und eine Leiteinrichtung 14 , die als Halbrohr ausgebildet an der Speicherwandung 1a angebracht ist.The figure shows a storage container 1 in a vertical position with a height greater than its diameter and with a possible arrangement of the hydraulic components: heat exchanger 2 and 3 , Pump 4 and 8th , Controller 5 and valves 6 and 7 , a breather 9 , a hot water extraction nozzle 11 , a heating-uptake and return pipe 12 , a feed pipe 13 and a guide 14 formed as a half tube on the storage wall 1a is appropriate.

Beim Betriebszustand „Zapfen" (Warmwasserabfuhr aus dem Speicher zu den Verbrauchern) befördert die Pumpe 8 heißes Wasser aus dem Entnahmestutzen 11 zu den Verbrauchern in einem geschlossenen Kreislauf bei geöffnetem Ventil 7 zurück in den Speicher 1 durch den Wasserstutzen 12. Während des Betriebszustandes „Beladen" fördert die Pumpe 4 kaltes Wasser in einem geschlossenen Kreislauf aus dem Wasserstutzen 12 durch die Wärmetauscher 3 und 2, in welchen das Wasser erwärmt wird, über das geöffnete Ventil 6 durch den Zuführungsstutzen 13 in eine Verweilzone 20 im unteren Teil der Leiteinrichtung 14. Von dort wird Wasser von hoher Temperatur zum Austritt 22 der Leiteinrichtung 14 nach oben, oder Wasser niederer Temperatur aus der Leiteinrichtung nach unten geleitet. Wasser mit einer Temperatur niederer als an der oberen Leiteinrichtungskante 22 aber höher als am unteren Leiteinrichtungsaustritt kann an einer der mittleren Austrittsöffnung 28 in das Speichervolumen strömen.In the operating state "spigot" (hot water removal from the storage to the consumers) the pump moves 8th hot water from the extraction nozzle 11 to consumers in a closed circuit with the valve open 7 back to the store 1 through the water pipe 12 , During the operating state "loading" the pump delivers 4 cold water in a closed circuit from the water nozzle 12 through the heat exchangers 3 and 2 in which the water is heated, via the open valve 6 through the feed pipe 13 in a residence zone 20 in the lower part of the guide 14 , From there, water of high temperature is discharged 22 the guide 14 to the top, or low-temperature water from the guide down. Water with a lower temperature than at the upper Leiteinrichtungskante 22 but higher than at the lower Leiteinrichtungsaustritt can at one of the central outlet opening 28 flow into the storage volume.
