Description

Die Erfindung bezieht sich auf einen Warmwasserspeicher in Verbindung mit mindestens einem an ihm montierten Hydraulikmodul zur thermischen Speicherbe- und -entladungThe invention relates to a hot water tank in conjunction with at least one mounted on it hydraulic module for thermal storage loading and unloading

Warmwasserspeicher dienen zur Bevorratung thermischer Energie. Zumeist wird in ihnen Heizungs- oder Brauchwasser bevorratet. Um dem Speicher thermische Energie zuzuführen, befindet sich häufig in dem Brauchwasserspeicher ein wendelförmiger Wärmetauscher, der von einem heizenden Medium durchströmt wird. Eine andere Möglichkeit besteht darin, dass dem Brauchwasserspeicher aus dem unteren Bereich kühles Wasser entzogen wird, welches in einem externen Wärmetauscher erwärmt und anschließend dem Speicher wieder zugeführt wird. Enthält der Warmwasserspeicher Heizungswasser, so muss die Wärme des Heizungswassers für die Brauchwasserbereitung in einem Wärmetauscher auf das Brauchwasser übertragen werden. Hierzu kann einerseits innerhalb des Warmwasserspeichers ein wendelförmiger Wärmetauscher angeordnet sein, welcher vom Brauchwasser durchströmt wird. Eine andere Möglichkeit besteht darin, warmes Heizungswasser aus dem Warmwasserspeicher abzuziehen und einen Teil dessen thermischer Energie in einem externen Plattenwärmetauscher auf das Brauchwasser zu übertragen.Hot water storage tanks are used to store thermal energy. In most cases, heating or service water is stored in them. In order to supply the storage thermal energy, is often located in the hot water tank, a helical heat exchanger, which is traversed by a heating medium. Another possibility is that the hot water tank from the lower area is withdrawn cool water, which is heated in an external heat exchanger and then returned to the memory. If the hot water storage tank contains heating water, the heat from the heating water for DHW heating must be transferred to the service water in a heat exchanger. For this purpose, on the one hand can be arranged within the hot water tank, a helical heat exchanger, which is flowed through by the hot water. Another possibility is to remove warm heating water from the hot water tank and transfer part of its thermal energy in an external plate heat exchanger to the hot water.

Häufig werden zum Be- und/oder Entladen eines Warmwasserspeichers Hydraulikmodule verwendet. Diese Hydraulikmodule stellen einen Baueinheit dar und enthalten außer einem Gehäuse zumindest eine Umwälzpumpe sowie einen Sekundärwärmetauscher, der zumeist als Plattenwärmetauscher ausgestaltet ist. Der Sekundärwärmetauscher ist mit zwei Anschlüssen mit dem Warmwasserspeicher verbunden, so dass Wasser abgezogen beziehungsweise zugeführt und somit Wärme in den Warmwasserspeicher eingebracht oder entzogen werden kann.Frequently hydraulic modules are used for loading and / or unloading a hot water storage tank. These hydraulic modules represent a structural unit and contain except one Housing at least one circulating pump and a secondary heat exchanger, which is usually designed as a plate heat exchanger. The secondary heat exchanger is connected to the hot water tank with two connections, so that water can be withdrawn or supplied and thus heat can be introduced into the hot water tank or withdrawn.

Gemäß dem Stand der Technik werden Hydraulikmodule an der Außenseite eines Warmwasserspeichers mittels Schrauben befestigt, anschließend werden die hydraulischen Leitungen der Hydraulikmodule mit den Anschlüssen des Warmwasserspeichers verbunden.According to the prior art, hydraulic modules are fastened to the outside of a hot water tank by means of screws, then the hydraulic lines of the hydraulic modules are connected to the connections of the hot water tank.

Der Erfindung liegt die Aufgabe zugrunde, die Aufhängung und Befestigung von Hydraulikmodulen an Warmwasserspeichern zu vereinfachen und die Wärmeverluste zu reduzieren.The invention has for its object to simplify the suspension and attachment of hydraulic modules to hot water tanks and to reduce the heat losses.

Erfindungsgemäß wird dies gemäß den Merkmalen des unabhängigen Anspruchs 1 dadurch gelöst, dass die hydraulischen Verbindungsleitungen zugleich als Befestigungselemente dienen.According to the invention this is achieved according to the features of independent claim 1, characterized in that the hydraulic connecting lines also serve as fasteners.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments of the invention will become apparent from the features of the dependent claims.

Die Erfindung wird nun anhand der Figuren detailliert erläutert. Hierbei zeigen:

  • Figur 1 einen Warmwasserspeicher mit zwei Hydraulikmodulen in der Seitenansicht (der Hydraulikmodule),
  • Figur 2 denselben Warmwasserspeicher mit zwei Hydraulikmodulen in der Frontalansicht (der Hydraulikmodule) sowie
  • Figur 3 die Verbindung des Warmwasserspeichers mit den einem Hydraulikmodul in einer Detailansicht.
The invention will now be explained in detail with reference to FIGS. Hereby show:
  • FIG. 1 a hot water tank with two hydraulic modules in the side view (the hydraulic modules),
  • FIG. 2 the same DHW cylinder with two hydraulic modules in the front view (the hydraulic modules) as well
  • FIG. 3 the connection of the hot water tank with a hydraulic module in a detailed view.

Die Figuren zeigen einen Warmwasserspeicher 1 mit vier hydraulischen Anschlüssen 5, 6, 7, 8 auf unterschiedlichem Höhenniveau, wobei die hydraulischen Anschlüsse 5, 6, 7, 8 eine Wand 4 des Warmwasserspeichers 1 auf einer Seite durchdringen. Der Warmwasserspeicher 1 ist von einer Dämmung 15 umschlossen, wobei die Dämmung 15 an der Stelle der hydraulischen Anschlüsse 5, 6, 7, 8 Ausnehmungen aufweist. Die hydraulischen Anschlüsse 5, 6, 7, 8 verfügen auf der Außenseite des Warmwasserspeichers über Gewinde. In diese Gewinde der hydraulischen Anschlüsse 5, 6, 7, 8 greifen vier Anschlussrohre 9, 10, 11, 12 ein und durchdringen somit die Dämmung 15.The figures show a hot water tank 1 with four hydraulic connections 5, 6, 7, 8 at different height level, wherein the hydraulic connections 5, 6, 7, 8 penetrate a wall 4 of the hot water tank 1 on one side. The hot water tank 1 is enclosed by an insulation 15, wherein the insulation 15 at the location of the hydraulic connections 5, 6, 7, 8 has recesses. The hydraulic connections 5, 6, 7, 8 have on the outside of the hot water tank threaded. In this thread of the hydraulic connections 5, 6, 7, 8 engage four connecting pipes 9, 10, 11, 12 and thus penetrate the insulation 15th

Auf die Dämmung 15 des Warmwasserspeichers 1 sind zwei Hydraulikmodule 2, 3 aufgesetzt. Die Rückwände 16, 17 der Hydraulikmodule 2, 3 verfügen über Durchbrüche, welche die Anschlussrohre 9, 10, 11, 12 umschließen. Auf der dem Warmwasserspeichers 1 abgewandten Seite der Anschlussrohre 9, 10, 11, 12 befinden sich Außengewinde, welche dazu dienen, mittels entsprechender Muttern die Rückwände 16, 17 der Hydraulikmodule 2, 3 am Warmwasserspeicher 1 zu befestigen.On the insulation 15 of the hot water tank 1, two hydraulic modules 2, 3 are placed. The rear walls 16, 17 of the hydraulic modules 2, 3 have openings, which surround the connection pipes 9, 10, 11, 12. On the side facing away from the hot water tank 1 side of the connecting pipes 9, 10, 11, 12 are external thread, which serve to fasten by means of appropriate nuts, the rear walls 16, 17 of the hydraulic modules 2, 3 on the hot water tank 1.

Die Anschlussrohre 9, 10, 11, 12 verfügen auf der dem Speicher zugewandten Seite innerhalb der Gewinde über radial umlaufende Nuten 13, in welche jeweils eine Radialdichtung 14 angeordnet ist.The connecting pipes 9, 10, 11, 12 have on the memory-facing side within the thread via radially circumferential grooves 13, in each of which a radial seal 14 is arranged.

Zur Montage der Hydraulikmodule 2, 3 werden zunächst in die Nuten 13 der Anschlussrohre 9, 10, 11, 12 Radialdichtungen 14 eingelegt. Dann werden die Anschlussrohre 9, 10, 11,12 durch die Öffnungen in der Dämmung 15 hindurch gesteckt und mit den hydraulischen Anschlüssen 5, 6, 7, 8 verschraubt. Die Radialdichtungen 14 dichten hierbei die Übergänge wasserdicht ab. Sind die Anschlussrohre 9, 10, 11, 12 verschraubt, so ragen diese über die Dämmung 15 des Warmwasserspeichers 1 hinaus. Die Anschlussrohre 9, 10, 11, 12 verfügen auf der dem Warmwasserspeicher 1 abgewandten Seite über einen größeren Durchmesser als auf der dem Warmwasserspeicher 1 zugeordneten Seite. Die Hydraulikmodule 2, 3 werden nun derart aufgesetzt, dass die Durchgänge in den Rückwänden 16, 17 der Hydraulikmodule 2, 3 über die Anschlussrohre 9, 10, 11, 12 gestülpt werden. Dadurch, dass die Rückwände 16, 17 auf dem größeren Durchmesser der Anschlussrohre 9, 10, 11, 12 aufliegen, wird die Flächenbelastung verringert. Anschließend werden Muttern 22 über die Außengewinde der Anschlussrohre 9, 10, 11, 12 geschraubt, so dass die Rückwände 16, 17 der Hydraulikmodule 2, 3 an den Warmwasserspeicher 1 gedrückt und mit ihm fest verbunden werden. Abschließend werden die Anschlussrohre 9, 10, 11, 12 mit den Pumpen 18, 19 und den Plattenwärmetauschern 20, 21 der Hydraulikmodule 2, 3 verbunden.For mounting the hydraulic modules 2, 3 are first in the grooves 13 of the connecting pipes 9, 10, 11, 12 radial seals 14 inserted. Then the connecting pipes 9, 10, 11, 12 are inserted through the openings in the insulation 15 and screwed to the hydraulic connections 5, 6, 7, 8. The radial seals 14 seal off the transitions waterproof. Are the connecting pipes 9, 10, 11, 12 screwed, so they protrude beyond the insulation 15 of the hot water tank 1 addition. The connecting pipes 9, 10, 11, 12 have on the side facing away from the hot water tank 1 side over a larger diameter than on the hot water tank 1 associated side. The hydraulic modules 2, 3 are now placed such that the passages in the rear walls 16, 17 of the hydraulic modules 2, 3 are slipped over the connecting pipes 9, 10, 11, 12. The fact that the rear walls 16, 17 rest on the larger diameter of the connection pipes 9, 10, 11, 12, the surface load is reduced. Subsequently, nuts 22 are screwed over the external threads of the connection pipes 9, 10, 11, 12, so that the rear walls 16, 17 of the hydraulic modules 2, 3 are pressed against the hot water tank 1 and firmly connected to it. Finally, the connection pipes 9, 10, 11, 12 are connected to the pumps 18, 19 and the plate heat exchangers 20, 21 of the hydraulic modules 2, 3.

Die Sekundärseite des Plattenwärmetauschers 20 des Hydraulikmoduls 2 wird mit einem Solarkollektor verbunden, so dass das Hydraulikmodul 2 als Solarstation dient. Die Sekundärseite des Plattenwärmetauschers 21 des Hydraulikmoduls 3 wird mit Brauchwasserleitungen verbunden, so dass das Hydraulikmodul 3 als Frischwasserstation dient.The secondary side of the plate heat exchanger 20 of the hydraulic module 2 is connected to a solar collector, so that the hydraulic module 2 serves as a solar station. The secondary side of the plate heat exchanger 21 of the hydraulic module 3 is connected to service water pipes, so that the hydraulic module 3 serves as a fresh water station.

Somit kann die hydraulische Verrohung zugleich als Befestigungselement genutzt werden. Hierdurch besteht nicht nur eine einfache Möglichkeit der Montage. Vielmehr wird auch eine bessere Dämmung des Warmwasserspeichers 1 erreicht, da außer der Verrohrung keine weiteren Wärmebrücken zur Befestigung der Hydraulikmodule 2, 3 zwischen Warmwasserspeichers 1 und der Umgebung die Dämmung 15 durchdringen.Thus, the hydraulic threat can also be used as a fastener. This not only provides a simple way of mounting. Rather, a better insulation of the hot water tank 1 is achieved because, except the piping no further thermal bridges for fixing the hydraulic modules 2, 3 between hot water tank 1 and the environment penetrate the insulation 15.

Auf die verlängernden Anschlussrohre 9, 10, 11, 12 kann verzichtet werden, wenn die hydraulischen Anschlüsse 5, 6, 7, 8 über entsprechende Längen verfügen. Zur Abdichtung zwischen den hydraulischen Anschlüssen 5, 6, 7, 8 und den Anschlussrohren 9, 10, 11, 12 können auch andere Dichtmittel (z.B. Hanf oder Teflonband) verwendet werden.On the extending connecting pipes 9, 10, 11, 12 can be omitted if the hydraulic connections 5, 6, 7, 8 have corresponding lengths. For sealing between the hydraulic connections 5, 6, 7, 8 and the connection pipes 9, 10, 11, 12, other sealing means (for example hemp or Teflon tape) may also be used.

Anstelle von Gewinden können zur hydraulischen Verbindung auch Schnellkupplungen eingesetzt werden.Instead of threads also quick couplings can be used for hydraulic connection.
