This unit is used in particular for connecting one or more heating or cooling sources with a plurality of heating or cooling circuits, wherein the unit comprises a container in the interior of which at least two superposed chambers are provided, which are in fluid communication with each other, and wherein connections for flow and Return of the heat or cold sources and for flow and return of the heating or cooling circuits are arranged on a peripheral wall of the container and connected to one of the chambers.

Ein derartiger Verteiler vermeidet zwar die Nachteile des erstgenannten Verteilers nach dem Stand der Technik, ist jedoch relativ aufwendig in seiner Konstruktion und benötigt einen relativ großen Bauraum, was seinen Einsatz erst bei Heizungsanlagen mit mehr als zwei oder drei Heizkreisen mit unterschiedlicher Heizkreisvorlauftemperatur und/oder mit mehreren Wärmequellen unterschiedlicher Vorlauftemperatur technisch und wirtschaftlich sinnvoll macht.Although such a distributor avoids the disadvantages of the former distributor according to the prior art, but is relatively expensive in its construction and requires a relatively large amount of space, which its use only in heating systems with more than two or three heating circuits with different heating circuit flow temperature and / or with several heat sources different flow temperature technically and economically makes sense.

Während die beiden in den vorgenannten Dokumenten zum Stand der Technik vorgestellten Lösungen ohne größeren Regelungsaufwand auskommen, sind aus der Praxis auch Lösungen für Heizungsanlagen, bei denen Verbraucherkreise mit unterschiedlichen Temperaturniveaus angeschlossen sind, bekannt, die für einen optimalen Betrieb dieser Anlagen einen hohen elektronischen Aufwand hinsichtlich Regelung und Steuerung einsetzen. Dies erfordert z.B. elektrisch verstellbare Ventile und Mischer, in ihrer Drehzahl regelbare Pumpen, diverse Temperaturfühler und eine übergeordnete elektronische Steuereinheit, was die Anlagen aufwendig und teuer macht.While the two presented in the aforementioned documents to the prior art solutions get along without major regulatory effort, solutions for heating systems in which consumer circuits are connected with different temperature levels, known from practice, for optimum operation of these systems a high electronic effort in terms Use regulation and control. This requires, for example, electrically adjustable valves and mixers, variable speed pumps, various temperature sensors and a higher-level electronic control unit, which makes the equipment complex and expensive.

Es stellt sich daher die Aufgabe, einen Heizkreisverteiler der eingangs genannten Art zu schaffen, der die vorstehend dargelegten Nachteile vermeidet und der bei technisch einfacher, kompakter Bauweise die Versorgung von wenigstens zwei Heizkreisen mit Heizmedium mit zwei unterschiedlichen Heizkreisvorlauftemperaturen ermöglicht.It is therefore an object to provide a heating circuit distributor of the type mentioned above, which avoids the disadvantages set out above and allows the supply of at least two heating circuits with heating medium with two different heating circuit flow temperatures in a technically simple, compact design.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit einem Heizkreisverteiler der eingangs genannten Art, der dadurch gekennzeichnet ist,

  • dass zusätzlich zu der Vorlaufkammer hoher Heizmediumtemperatur und der Rücklaufkammer niedriger Heizmediumtemperatur eine Zwischenkammer mittlerer Heizmediumtemperatur im Gehäuse angeordnet ist,
  • dass mit der Vorlaufkammer hoher Heizmediumtemperatur mindestens ein Heizkreisvorlaufanschluss eines Heizkreises mit hoher Heizmediumvorlauftemperatur verbunden ist,
  • dass mit der Zwischenkammer mindestens ein Heizkreisrücklaufanschluss eines Heizkreises mit mittlerer Heizmediumrücklauftemperatur und mindestens ein Heizkreisvorlaufanschluss eines Heizkreises mit mittlerer Heizmediumvorlauftemperatur verbunden sind,
  • dass mit der Rücklaufkammer niedriger Heizmediumtemperatur mindestens ein Heizkreisrücklaufanschluss eines Heizkreises mit niedriger Heizmediumrücklauftemperatur verbunden ist und
  • dass die Zwischenkammer und die Weichenkammer über mindestens eine Verbindung innerhalb des Gehäuses strömungsmäßig miteinander verbunden sind.
The solution of this object succeeds according to the invention with a heating circuit distributor of the type mentioned, which is characterized
  • an intermediate chamber of medium heating medium temperature is arranged in the housing in addition to the flow chamber of high heating medium temperature and the return chamber of low heating medium temperature,
  • in that at least one heating circuit flow connection of a heating circuit having a high heating medium flow temperature is connected to the flow chamber of high heating medium temperature,
  • in that at least one heating circuit return connection of a heating circuit having an average heating medium return temperature and at least one heating circuit supply connection of a heating circuit having an average heating medium supply temperature are connected to the intermediate chamber,
  • that at least one heating circuit return connection of a heating circuit with a low heating medium return temperature is connected to the return chamber of low heating medium temperature, and
  • in that the intermediate chamber and the switch chamber are fluidly connected to one another via at least one connection within the housing.

Mit der Erfindung wird ein Heizkreisverteiler geschaffen, mit dem wenigstens zwei Heizkreise mit Heizmedium zweier unterschiedlicher Temperaturen versorgt werden können und mit dem gleichzeitig über die integrierte hydraulische Weiche alle gegebenenfalls im Betrieb auftretenden Volumenstromdifferenzen sowohl zwischen den verschiedenen Heizkreisen als auch zwischen dem Kesselkreis und den Heizkreisen ausgeglichen werden können. Ein wirtschaftlich optimaler Betrieb ergibt sich dann, wenn die Rücklauftemperatur des Heizkreises mit der höheren Heizmediumtemperatur im Bereich der Vorlauftemperatur des Heizkreises mit der niedrigeren Heizmediumtemperatur liegt; die Heizkreise können dann strömungsmäßig in Reihe geschaltet von dem Heizmedium nacheinander durchströmt werden, bevor das Heizmedium dem Heizkessel zur erneuten Erhitzung wieder zugeführt wird. Hierbei wird die im Heizmedium enthaltende Wärmeenergie optimal genutzt und dem Heizkessel wird das Heizmedium mit der niedrigsten möglichen Temperatur zu erneuten Erhitzung zugeführt, was Vorteile insbesondere beim Einsatz eines Brennwertkesseln als Heizkessel mit sich bringt. Dabei besitzt der Heizkreisverteiler nur eine geringe Baugröße, die praktisch nicht größer ist als bei den bekannten Verteilern gemäß dem oben an erster Stelle genannten Stand der Technik. Gegenüber Verteilern nach dem oben an zweiter Stelle genannten Stand der Technik besitzt der erfindungsgemäßen Heizkreisverteiler den Vorteil einer technisch einfacheren Konstruktion und wesentlich kompakteren Bauweise. Im Vergleich zu dem oben an dritter Stelle genannten Stand der Technik bietet der erfindungsgemäße Heizkreisverteiler eine kostengünstige Lösung zur Versorgung von Heizungsanlagen, bei denen die Verbraucherkreise mit unterschiedlichen Temperaturniveaus arbeiten. Dabei kann vorteilhaft auf aufwendige Komponenten und Elemente mit einem größeren Regelungsaufwand zur Steuerung und Regelung verzichtet werden.With the invention, a heating circuit manifold is provided with which at least two heating circuits can be supplied with heating medium of two different temperatures and compensated with the simultaneously occurring via the integrated hydraulic switch all possibly occurring during operation volume flow differences both between the various heating circuits and between the boiler circuit and the heating circuits can be. An economically optimal operation results when the return temperature of the heating circuit with the higher heating medium temperature is in the range of the flow temperature of the heating circuit with the lower heating medium temperature; the heating circuits can then be flow-connected in series through which the heating medium flows successively, before the heating medium is returned to the boiler for renewed heating. Here, the heat energy contained in the heating medium is used optimally and the boiler the heating medium is supplied to the lowest possible temperature for reheating, which brings advantages in particular when using a condensing boilers as a boiler with it. In this case, the Heizkreisverteiler has only a small size, which is practically no larger than in the known distributors according to the above-mentioned in the first place of the prior art. Compared to distributors according to the above second prior art, the heating circuit distributor according to the invention has the advantage of a technically simpler design and much more compact design. In comparison with the prior art mentioned above in the third place, the heating circuit distributor according to the invention offers a cost-effective solution for supplying heating systems in which the consumer circuits operate at different temperature levels. It can be advantageously dispensed with complex components and elements with a greater regulatory effort for control and regulation.

Grundsätzlich können die verschiedenen Kammern des Heizkreisverteilers an beliebigen Stellen im Gehäuse untergebracht sein. Aus Gründen einer übersichtlichen und günstigen Strömungsführung und Anschlussanordnung ist aber erfindungsgemäß bevorzugt vorgesehen, dass die Vorlaufkammer, die Rücklaufkammer und die Zwischenkammer in einem oberen Teil des Gehäuses angeordnet sind und dass die Weichenkammer darunter in einem unteren Teil des Gehäuses angeordnet ist. Die Vorlaufkammer, die Rücklaufkammer und die Zwischenkammer können in einer Höhe angeordnet sein, so dass dann auch die verschiedenen Heizkreisvorlaufanschlüsse und -rücklaufanschlüsse entsprechend auf einer Höhe angeordnet sein können. Die mit der Weichenkammer verbundenen Kesselvorlauf- und Kesselrücklaufanschlüsse können entfernt von den Heizkreisvorlauf- und Heizkreisrücklaufanschlüssen am Gehäuse angeordnet sein. Insgesamt ergibt dies eine übersichtliche, Anschlussfehler vermeidende Anschlussanordnung für den Heizkreisverteiler.In principle, the various chambers of the heating circuit distributor can be accommodated anywhere in the housing. For reasons of a clear and favorable flow guidance and connection arrangement, however, according to the invention it is preferably provided that the flow chamber, the return chamber and the intermediate chamber are arranged in an upper part of the housing and that the switch chamber is arranged underneath in a lower part of the housing. The flow chamber, the return chamber and the intermediate chamber may be arranged at a height, so that then the various heating circuit flow connections and return connections can be arranged correspondingly at a height. The boiler feed and boiler return ports connected to the switch chamber may be remote from the heater circuit supply and return circuits on the housing. Overall, this results in a clear, connection error-avoiding connection arrangement for the heating circuit manifold.

Zwecks einer einfachen technischen Konstruktion und günstigen Herstellbarkeit des Heizkreisverteilers ist bevorzugt vorgesehen, dass das Gehäuse eine Trennwand aufweist, welche die Vorlaufkammer, die Rücklaufkammer und die Zwischenkammer unterseitig und die Weichenkammer oberseitig begrenzt und welche mindestens drei Durchbrechungen zur Herstellung der Strömungsverbindungen zwischen der Weichenkammer einerseits und der Vorlaufkammer, der Rücklaufkammer und der Zwischenkammer andererseits aufweist. Trotz ihrer diversen Funktionen ist die Trennwand hier ein einfaches und kostengünstiges Bauteil.For the purpose of a simple technical construction and cheap manufacturability of Heizkreisverteilers is preferably provided that the housing has a partition, the upper side delimits the flow chamber, the return chamber and the intermediate chamber and the upper chamber and which at least three openings for producing the flow connections between the switch chamber on the one hand and the flow chamber, the return chamber and the intermediate chamber on the other hand. Despite its various functions, the dividing wall here is a simple and cost-effective component.

Weiter schlägt die Erfindung vor, dass in Längsrichtung des Gehäuses gesehen die Vorlaufkammer und die Rücklaufkammer stirnendseitig im Gehäuse angeordnet sind und dass sich die Zwischenkammer über den verbleibenden mittleren Teil der Länge des Gehäuses zwischen der Vorlaufkammer und der Rücklaufkammer erstreckt. Mit dieser Anordnung der genannten Kammern im Gehäuse relativ zueinander wird eine übersichtliche Zuordnung der verschiedenen Anschlüsse dieser Kammern ermöglicht. Zusätzlich werden Wärmeverluste innerhalb des Verteilers gering gehalten, weil keine besonders großen Temperaturdifferenzen zwischen den einander benachbarten Kammern auftreten.Further, the invention proposes that seen in the longitudinal direction of the housing, the flow chamber and the return chamber are arranged end face in the housing and that the intermediate chamber extends over the remaining central part of the length of the housing between the flow chamber and the return chamber. With this arrangement of said chambers in the housing relative to each other a clear assignment of the various ports of these chambers is made possible. In addition, heat losses within the distributor are kept low because no particularly large temperature differences occur between the adjacent chambers.

Die absoluten Kammergrößen und das Verhältnis der Kammergrößen relativ zueinander richtet sich nach dem Bedarf der zugehörigen Heizungsanlage, insbesondere danach, wie viele Abnehmer- oder Heizkreise in den unterschiedlichen Temperaturniveaus an der jeweiligen Kammer angebunden sind und welcher Volumenstrom an Heizmedium von den Heizkreisen benötigt wird.The absolute chamber sizes and the ratio of the chamber sizes relative to each other depends on the needs of the associated heating system, in particular how many customer or heating circuits are connected in the different temperature levels at the respective chamber and what volume flow of heating medium is required by the heating circuits.

Um eine günstige, übersichtliche und platzsparende Verrohrung des erfindungsgemäßen Heizkreisverteiler zu ermöglichen, sind bevorzugt die Heizkreisvorlaufanschlüsse und Heizkreisrücklaufanschlüsse oberseitig und der Kesselvorlaufanschluss und der Kesselrücklaufanschluss unterseitig an dem Gehäuse angeordnet. Alle zum Anschluss des Heizkreisverteilers nötigen Rohrleitungen können somit vorteilhaft in einer Ebene angeordnet werden.In order to allow a cheap, clear and space-saving piping of the heating circuit manifold according to the invention, preferably the heating circuit flow connections and Heizkreisrücklaufanschlüsse are on the upper side and the boiler flow connection and the boiler return port on the underside of the housing. All necessary for connection of the heating circuit manifold pipes can thus be arranged advantageously in a plane.

Im normalen Betrieb des Heizkreisverteilers, in dem keine Ausgleichsströmungen über die hydraulische Weiche fließen, sollen die Heizmediumströme möglichst verlustarm durch den Heizkreisverteiler strömen können. Zu diesem Zweck wird vorgeschlagen, dass der Kesselvorlaufanschluss, der mindestens eine mit der Vorlaufkammer verbundene Heizkreisvorlaufanschluss und die zugehörige Durchbrechung in der Trennwand miteinander fluchtend angeordnet sind und dass der Kesselrücklaufanschluss, der mindestens eine mit der Rücklaufkammer verbundene Heizkreisrücklaufanschluss und die zugehörige Durchbrechung in der Trennwand miteinander fluchtend angeordnet sind. Strömungsumlenkungen im Gehäuse des Verteilers, die zu einem erhöhten Strömungswiderstand führen würden, werden so vermieden.During normal operation of the heating circuit distributor, in which no compensating flows flow via the hydraulic separator, the heating medium flows should be able to flow through the heating circuit distributor with as little loss as possible. For this purpose, it is proposed that the boiler feed connection, the at least one associated with the flow chamber Heizkreisvorlaufanschluss and the associated aperture in the partition are aligned with each other and that the boiler return port, the at least one connected to the return chamber Heizkreisrücklaufanschluss and the associated opening in the partition with each other are arranged in alignment. Flow deflections in the housing of the distributor, which would lead to increased flow resistance, are thus avoided.

Zur Erzielung günstiger Strömungsverhältnisse zwischen der Weichenkammer und der Zwischenkammer im Falle von Ausgleichsströmungen ist bevorzugt vorgesehen, dass die Zwischenkammer und die Weichenkammer über zwei in Längsrichtung des Gehäuses voneinander beabstandete Durchbrechungen in der Trennwand miteinander strömungsmäßig verbunden sind. Aufgrund des Abstandes der beiden Durchbrechungen liegt die eine Durchbrechung näher zum Kesselvorlaufanschluss und die andere Durchbrechung näher zum Kesselrücklaufanschluss, so dass durch die erstgenannte Durchbrechung im Wesentlichen Heizmedium vom Kesselvorlaufanschluss aus der Weichenkammer in die Zwischenkammer strömen kann, während durch die andere Durchbrechung im Wesentlichen Heizmedium aus der Zwischenkammer in die Weichenkammer und dann zum Kesselrücklaufanschluss strömen kann.In order to achieve favorable flow conditions between the switch chamber and the intermediate chamber in the case of compensating flows, it is preferably provided that the intermediate chamber and the switch chamber are fluidly connected to one another via two openings in the partition which are spaced apart from one another in the longitudinal direction of the housing. Due to the distance between the two openings, the one opening is closer to the boiler supply connection and the other opening closer to the boiler return connection, so that can flow through the first-mentioned opening substantially heating medium from the boiler supply connection from the switch chamber in the intermediate chamber, while through the other opening substantially heating medium the intermediate chamber can flow into the switch chamber and then to the boiler return port.

Eine weitere Maßnahme zur Erzielung günstiger Strömungsverhältnisse besteht darin, dass vorzugsweise der mit der Zwischenkammer verbundene mindestens eine Heizkreisrücklaufanschluss und mindestens eine Heizkreisvorlaufanschluss jeweils fluchtend mit einer der Durchbrechungen in der Trennwand zwischen Weichenkammer und Zwischenkammer angeordnet sind.Another measure for achieving favorable flow conditions is that preferably the at least one heating circuit return connection connected to the intermediate chamber and at least one heating circuit supply connection are each arranged in alignment with one of the openings in the partition between the switch chamber and the intermediate chamber.

Um eine unerwünschte Kurzschlussströmung vom Kesselvorlaufanschluss durch die Weichenkammer zum Kesselrücklaufanschluss zu vermeiden oder zumindest auf ein nicht störendes Maß zu begrenzen, ist erfindungsgemäß vorgesehen, dass den beiden Durchbrechungen jeweils ein sich über die Höhe der Weichenkammer erstreckender Rohrstutzen mit wenigstens einer seitlichen Öffnung zugeordnet ist, wobei die Öffnung jeweils zum nächstgelegenen Kesselanschluss weist. Zweckmäßig ist dabei der Außendurchmesser der Rohrstutzen so gewählt, dass sie den größten Teil des Querschnitts der Weichenkammer einnehmen, jedoch noch einen ausreichenden Querschnitt zur Ermöglichung der bedarfsweisen Ausgleichsströmungen freilassen. Für die Ausgleichsströmungen reicht in der Praxis ein verbleibender Querschnitt von etwa 10 bis 20% des gesamten Querschnitts der Weichenkammer aus. Die Rohrstutzen können so einen relativ großen Innendurchmesser aufweisen, was wiederum vorteilhaft für die bedarfsweisen Ausgleichsströmungen zwischen der Weichenkammer und der Zwischenkammer ist. Ein hier gewünschter Strömungswiderstand kann durch geeignete Wahl der Größe der seitlichen Öffnung der Rohrstutzen passend eingestellt werden.In order to avoid an undesirable short-circuit flow from the boiler flow connection through the switch chamber to the boiler return connection or at least to limit a non-interfering measure, the invention provides that the two openings each one is assigned over the height of the switch chamber pipe socket with at least one lateral opening, wherein the opening points to the nearest boiler connection. Appropriately, the outer diameter of the pipe socket is chosen so that they occupy most of the cross section of the switch chamber, but still leave a sufficient cross-section to enable the demand-compensating flows. In practice, a residual cross section of about 10 to 20% of the total cross section of the switch chamber is sufficient for the compensation flows. The pipe socket can thus have a relatively large inner diameter, which in turn is advantageous for the demand-compensating flows between the switch chamber and the intermediate chamber. A desired flow resistance can be suitably adjusted by a suitable choice of the size of the lateral opening of the pipe socket.

Das durch den zugehörigen Heizkreisrücklaufanschluss in die Zwischenkammer einströmende Heizmedium aus dem Heizkreis mit der höheren Heizmediumtemperatur soll bevorzugt in den ebenfalls der Zwischenkammer zugeordneten Heizkreisvorlaufanschluss für den Heizkreis mit der niedrigen Heizmediumtemperatur zuströmen. Um diese gewünschte Strömung zu unterstützen, ist gemäß einer weiteren Ausgestaltung des Heizkreisverteilers vorgesehen, dass in der Zwischenkammer eine diese in einen oberen und unteren Kammerteil unterteilende, für das Heizmedium durchlässige und für dieses einen Strömungswiderstand darstellende Zwischenplatte angeordnet ist. Hiermit wird für die vorerwähnte gewünschte Strömung ein niedriger Strömungswiderstand erreicht, während für bedarfsweise auftretende Ausgleichsströmungen das Heizmedium durch die einen Strömungswiderstand darstellende Zwischenplatte strömen muss.The heating medium flowing in through the associated heating circuit return connection into the intermediate chamber from the heating circuit with the higher heating medium temperature should preferably flow into the heating circuit supply connection for the heating circuit with the low heating medium temperature likewise assigned to the intermediate chamber. In order to support this desired flow, according to a further embodiment of the heating circuit distributor it is provided that in the intermediate chamber there is arranged an intermediate plate which subdivides this into an upper and lower chamber part, is permeable to the heating medium and represents a flow resistance. Hereby, a low flow resistance is achieved for the aforementioned desired flow, while for necessary occurring compensating flows the heating medium must flow through the flow resistance performing intermediate plate.

Zwecks einfacher Fertigung ist die Zwischenplatte bevorzugt durch ein Lochblech gebildet. Ein gewünschter Strömungswiderstand des Lochblechs kann einfach durch die Dichte und/oder die freie Querschnittsgröße der Löcher festgelegt werden.For ease of manufacture, the intermediate plate is preferably formed by a perforated plate. A desired flow resistance of the perforated plate can be determined simply by the density and / or the free cross-sectional size of the holes.

Eine zusätzliche oder alternative technische Maßnahme zur Vermeidung oder Begrenzung von Kurzschlussströmungen zwischen dem Heizkesselvorlaufanschluss und dem Heizkesselrücklaufanschluss durch die Weichenkammer besteht darin, dass vorzugsweise von der Trennwand unterseitig und/oder von der Bodenwand oberseitig eine oder mehrere quer angeordnete Strömungsleitwände ausgehen, die sich über einen Teil der Höhe der Weichenkammer erstrecken. Der freie Strömungsquerschnitt der Weichenkammer kann so an einer oder mehreren Stellen auf ein gewünschtes Maß reduziert werden.An additional or alternative technical measure for avoiding or limiting short circuit flows between the boiler flow connection and the boiler return connection through the switch chamber is that preferably one or more transversely arranged flow guide walls project from the partition wall on the underside and / or from the bottom wall on one side extend the height of the switch chamber. The free flow cross section of the switch chamber can thus be reduced to one or more locations to a desired level.

Bevorzugt ist dabei weiter vorgesehen, dass sich die Strömungsleitwände maximal über die halbe Höhe der Weichenkammer erstrecken und in Längsrichtung der Weichenkammer gesehen voneinander beabstandet jeweils innen vom Heizkesselvorlaufanschluss bzw. vom Heizkesselrücklaufanschluss liegen. In dieser Anordnung schirmen die Strömungsleitwände vorteilhaft die Durchbrechung(en) zwischen der Weichenkammer und der Zwischenkammer von der Heizmediumströmung vom Kesselvorlaufanschluss in die Vorlaufkammer und von der Heizmediumströmung aus der Rücklaufkammer in den Kesselrücklaufanschluss ab, erlauben aber gleichzeitig die gegebenenfalls nötigen Ausgleichsströmungen.Preferably, it is further provided that the Strömungsleitwände extend a maximum of half the height of the switch chamber and seen in the longitudinal direction of the switch chamber spaced from each other in each case from the boiler flow connection or from the boiler return port. In this arrangement, the flow baffles advantageously shield the aperture (s) between the sipe chamber and the intermediate chamber from the heating medium flow from the boiler feed port to the flow chamber and from the heating medium flow from the return chamber to the boiler return port, but at the same time allow for any necessary counterbalancing flows.

Schließlich ist für den erfindungsgemäßen Heizkreisverteiler noch vorgesehen, dass wenigstens eine Montagemuffe für einen Temperaturfühler am Gehäuse, vorzugsweise im Bereich des Heizkesselvorlaufanschlusses, angeordnet ist. Auf diese Weise können ein oder mehrere Temperaturfühler, die Temperaturdaten für eine Steuerung einer zugehörigen Heizungsanlage aufnehmen, einfach an dem Heizkreisverteiler angebracht werden.Finally, it is provided for the heating circuit distributor according to the invention that at least one mounting sleeve for a temperature sensor on the housing, preferably in the region of the boiler flow connection, is arranged. In this way, one or more temperature sensors that receive temperature data for control of an associated heating system can be easily attached to the heating circuit manifold.

Zwecks einfacher und kostengünstiger Fertigung besteht der erfindungsgemäße Heizkreisverteiler zweckmäßig aus miteinander verschweißten Zuschnitten aus Stahlblech und aus Rohrabschnitten, wobei die Anschlussstutzen bildenden Rohrabschnitte zweckmäßig mit vorgefertigten Anschlussgewinden zum einfachen Anschluss weiterführender Rohrleitungen ausgebildet sind.For the purpose of simple and cost-effective production, the heating circuit distributor according to the invention expediently consists of blanks made of sheet steel and of pipe sections which are welded together, wherein the pipe connections forming connecting pieces are expediently designed with prefabricated connecting threads for the simple connection of further-running pipelines.

Wie an sich bekannt, kann der Heizkreisverteiler mit einem Entleerungsstutzen und/ oder einem Schlammsammelraum und/oder einem Magnetabscheider und/oder einem Entlüftungsventil ausgestattet sein, wenn dafür Bedarf besteht.As known per se, the heating circuit manifold may be equipped with a drain port and / or a sludge collection space and / or a magnetic separator and / or a vent valve, if needed.

In der Zwischenkammer 4 ist parallel und mit Abstand zur Trennwand 16 eine Zwischenplatte 17, hier in Form eines Lochblechs, angeordnet, welche die Zwischenkammer 4 in einen oberen Kammerteil 40 und einen unteren Kammerteil 40' unterteilt.In the intermediate chamber 4, an intermediate plate 17, here in the form of a perforated plate, is arranged parallel to and at a distance from the dividing wall 16, dividing the intermediate chamber 4 into an upper chamber part 40 and a lower chamber part 40 '.

Die Trennwand 16 weist im vorliegenden Ausführungsbeispiel insgesamt vier Durchbrechungen 61, 62, 70 und 70' auf. Die Durchbrechung 61 verbindet die Weichenkammer 5 nahe der Stirnwand 15 mit der Vorlaufkammer 2. Die Durchbrechung 62 verbindet die Rücklaufkammer 3 nahe der anderen Stirnwand 15' mit der Weichenkammer 5. Die beiden Durchbrechungen 70 und 70' verbinden die Zwischenkammer 4 und die Weichenkammer 5 miteinander und sind in Längsrichtung des Gehäuses 10 voneinander beabstandet.The partition 16 has in the present embodiment a total of four apertures 61, 62, 70 and 70 '. The opening 61 connects the switch chamber 5 near the end wall 15 with the flow chamber 2. The opening 62 connects the return chamber 3 near the other end wall 15 'with the switch chamber 5.

In der Weichenkammer 5 sind bei dem gezeigten Ausführungsbeispiel weiterhin zwei quer zur Weichenkammer 5 ausgerichtete Strömungsleitwände 18, 18' vorgesehen, die sich jeweils von der Unterseite der Trennwand 16 ausgehend über einen Teil der Höhe der Weichenkammer 5 nach unten in diese hinein erstrecken. Alternativ zur dargestellten Ausführung können auch eine oder beide Strömungsleitwände 18, 18' auf der Oberseite der Bodenwand 11 angeordnet sein.In the turnout chamber 5, two flow guide walls 18, 18 'aligned transversely to the turnout chamber 5 are provided in the embodiment shown, each extending from the underside of the dividing wall 16 downwards over part of the height of the turnout chamber 5.

An die genannten Anschlüsse 21, 32, 41 und 42 sind weiterführende Rohrleitungen anschließbar, die den Heizkreisverteiler 1 mit Heizeinrichtungen, die hier nicht dargestellt sind, verbinden.On the outside of the top wall 12 of the housing 10 there are provided a total of four ports, namely from right to left, a first heating circuit flow connection 21, which is fluidly connected to the flow chamber 2, a first heating circuit return connection 42, which is fluidly connected to the intermediate chamber 4, a second Heating circuit flow connection 41, which is fluidly connected to the intermediate chamber 4, and a second heating circuit return connection 32, which is fluidly connected to the return chamber 3. On the above connections 21, 32, 41 and 42 further piping can be connected, which connect the heating circuit manifold 1 with heaters, which are not shown here.

An der Unterseite der Bodenwand 11 sind zwei weitere Anschlüsse angeordnet, nämlich nahe der rechten Stirnwand 15 ein Heizkesselvorlaufanschluss 51 und nahe der linken Stirnwand 15' ein Heizkesselrücklaufanschluss 52. Mit den Anschlüssen 51, 52 sind weiterführende Rohrleitungen verbindbar, die den Heizkreisverteiler 1 mit einem oder mehreren Heizkesseln verbinden.On the underside of the bottom wall 11, two further connections are arranged, namely near the right end wall 15, a boiler flow connection 51 and near the left end wall 15 'a boiler return port 52. With the connections 51, 52 can be connected further pipelines that connect the heating circuit 1 with one or more boilers.

An der in Figur 1 rechten Stirnwand 15 ist in Höhe der Weichenkammer 5 eine Muffe 80 angebaut, die zur Aufnahme eines Temperaturfühlers dient, welcher die Vorlauftemperatur des in den Heizkreisverteiler 1 einströmenden Heizmediums erfasst.At the in FIG. 1 right end wall 15 is in the amount of the turnout chamber 5, a sleeve 80 is grown, which serves to receive a temperature sensor, which detects the flow temperature of the inflowing into the heating circuit manifold 1 heating medium.

Wie die Figur 1 veranschaulicht, sind hier der Heizkesselvorlaufanschluss 51, die Durchbrechung 61 und der Heizkreisvorlaufanschluss 21 fluchtend miteinander angeordnet; ebenso sind der Heizkesselrücklaufanschluss 52, die Durchbrechung 62 und der Heizkreisrücklaufanschluss 32 miteinander fluchtend ausgerichtet. Auch der Rohrstutzen 71, die Durchbrechung 70 und der Heizkreisrücklaufanschluss 42 besitzen hier eine miteinander fluchtende Ausrichtung, ebenso wie der Rohrstutzen 71', die Durchbrechung 70' und der Heizkreisvorlaufanschluss 41.As the FIG. 1 illustrated, here the boiler inlet port 51, the opening 61 and the heating circuit flow connection 21 are arranged in alignment with each other; Similarly, the boiler return port 52, the aperture 62 and the heating circuit return port 32 are aligned with each other. Also, the pipe socket 71, the aperture 70 and the heating circuit return port 42 have here aligned alignment, as well as the pipe socket 71 ', the opening 70' and the heating circuit flow connection 41st

Figur 2 zeigt den Heizkreisverteiler 1 aus Figur 1, wieder mit offen dargestellter Vorderseite, in einer zweiten perspektivischen Ansicht schräg von rechts vorne. Im Unterschied zu der Figur 1 ist nun an dem rechten Rohrstutzen 71 dessen zur rechten Stirnwand 15 weisende Öffnung 72 sichtbar. Hinsichtlich der weiteren in Figur 2 sichtbaren Einzelteile des Heizkreisverteilers 1 und der eingezeichneten Bezugsziffern wird auf die vorhergehende Beschreibung der Figur 1 verwiesen. FIG. 2 shows the heating circuit manifold 1 from FIG. 1 , again with open front, in a second perspective view obliquely from the right front. Unlike the FIG. 1 is now visible on the right pipe socket 71 whose facing the right end wall 15 opening 72. Regarding the further in FIG. 2 visible individual parts of the heating circuit 1 and the reference numerals drawn is to the previous description of FIG. 1 directed.

Figur 3 der Zeichnung zeigt den Heizkreisverteiler 1 aus den Figuren 1 und 2 in einem ersten beispielhaften Betriebszustand, in schematischer Darstellung. Durch den Heizkesselvorlaufanschluss 51 strömt erhitztes Heizmedium, wie Wasser, mit einer Temperatur von hier beispielsweise etwa 60 °C in den Heizkreisverteiler 1 und durch dessen Weichenkammer 5 und die Durchbrechung 61 hindurch in die Vorlaufkammer 2 ein. FIG. 3 the drawing shows the heating circuit manifold 1 from the FIGS. 1 and 2 in a first exemplary operating state, in a schematic representation. Through the boiler inlet port 51 heated heating medium, such as water flows at a temperature of here, for example, about 60 ° C in the heating circuit manifold 1 and through the turnout chamber 5 and the aperture 61 into the flow chamber 2 a.

Mit dem Heizkreisvorlaufanschluss 21 und dem Heizkreisrücklaufanschluss 42 ist ein erster Heizkreis verbunden, der beispielsweise Heizkörper versorgt, welche eine relativ hohe Vorlauftemperatur von beispielsweise etwa 60 °C für ihren Betrieb benötigen. Über eine Zirkulationspumpe 91 wird das Heizmedium aus der Vorlaufkammer 2 des Heizkreisverteilers 1 durch den Heizkreisvorlaufanschluss 21 hindurch dem ersten Heizkreis zugeführt. Nach Abgabe von Wärme aus dem Heizmedium in den hier nicht dargestellten Heizkörpern strömt das Heizmedium mit verminderter Temperatur von hier beispielsweise etwa 45 °C durch den ersten Heizkreisrücklaufanschluss 42 in die Zwischenkammer 4 des Heizkreisverteilers 1.With the heating circuit flow connection 21 and the heating circuit return connection 42, a first heating circuit is connected, for example, supplies radiators, which require a relatively high flow temperature of, for example, about 60 ° C for their operation. Via a circulation pump 91, the heating medium from the flow chamber 2 of the heating circuit manifold 1 through the heating circuit flow connection 21 through the first heating circuit is supplied. After delivery of heat from the heating medium in the radiators, not shown here, the heating medium flows with reduced Temperature from here, for example, about 45 ° C through the first heating circuit return connection 42 into the intermediate chamber 4 of the heating circuit manifold. 1

Durch die Zwischenkammer 4 strömt das Heizmedium zum zweiten Heizkreisvorlaufanschluss 41 und wird von dort mittels einer zweiten Zirkulationspumpe 92 durch einen zweiten Heizkreis gefördert, der hier beispielsweise eine Fußbodenheizung versorgt. Die Zwischenplatte 17 bildet dabei einen Strömungswiderstand für das Heizmedium, der dafür sorgt, dass in der Zwischenkammer 4 das Heizmedium bevorzugt vom Heizkreisrücklaufanschluss 42 zum Heizkreisvorlaufanschluss 41 strömt und nicht den Weg durch die Zwischenplatte 17, den Rohrstutzen 71' und die Weichenkammer 5 zum Heizkesselrücklaufanschluss 52 nimmt.Through the intermediate chamber 4, the heating medium flows to the second heating circuit flow connection 41 and is conveyed from there by means of a second circulation pump 92 through a second heating circuit, which supplies, for example, a floor heating system here. The intermediate plate 17 forms a flow resistance for the heating medium, which ensures that in the intermediate chamber 4, the heating medium flows preferably from Heizkreisrücklaufanschluss 42 to Heizkreisvorlaufanschluss 41 and not the way through the intermediate plate 17, the pipe socket 71 'and the switch chamber 5 to the boiler return port 52nd takes.

Die Fußbodenheizung benötigt eine geringere Vorlauftemperatur, beispielsweise von etwa 45 °C, was ziemlich exakt der Rücklauftemperatur des ersten Heizkreises entspricht. Nach Durchströmen der Fußbodenheizung fließt das nun nochmals abgekühlte Heizmedium mit einer weiter reduzierten Temperatur, hier beispielsweise von etwa 35 °C, durch den zweiten Rücklaufanschluss 32 in die Rücklaufkammer 3. Aus der Rücklaufkammer 3 strömt das Heizmedium durch die Durchbrechung 62 und die Weichenkammer 5 in den Heizkesselrücklaufanschluss 52 und durch diesen zu dem hier nicht dargestellten Heizkessel zur erneuten Erhitzung, um dann wieder durch den Heizkesselvorlaufanschluss 51 dem Heizkreisverteiler 1 zugeführt zu werden.The underfloor heating requires a lower flow temperature, for example, of about 45 ° C, which corresponds almost exactly to the return temperature of the first heating circuit. After flowing through the underfloor heating, the now again cooled heating medium flows with a further reduced temperature, here for example of about 35 ° C, through the second return port 32 in the return chamber 3. From the return chamber 3, the heating medium flows through the opening 62 and the switch chamber 5 in the Heizkesselrücklaufanschluss 52 and through this to the boiler not shown here for reheating, in order then again to be supplied through the boiler flow connection 51 to the heating circuit manifold 1.

In dem in Figur 3 dargestellten Betriebszustand haben beide Heizkreise einen gleich großen Volumenstrombedarf an Heizmedium, so dass Ausgleichsströmungen zwischen den verschiedenen Kreisen nicht erforderlich sind. Vielmehr werden hier die beiden Heizkreise in einer reinen Reihenschaltung nacheinander von dem Heizmedium durchströmt. Die im Heizmedium enthaltende Wärmeenergie wird auf diese Weise optimal ausgenutzt und das Heizmedium strömt mit einer vorteilhaft niedrigen Temperatur in die Rücklaufkammer 3 zurück. Besonders in Verbindung mit einem Brennwertkessel als Heizkessel ergibt sich so ein besonderes wirtschaftlicher Heizbetrieb.In the in FIG. 3 shown operating state, both heating circuits have the same volume flow requirement of heating medium, so that balancing flows between the different circuits are not required. Rather, here the two heating circuits are flowed through in succession in a pure series connection of the heating medium. The thermal energy contained in the heating medium is optimally utilized in this way and the heating medium flows back into the return chamber 3 with an advantageously low temperature. Especially in connection with a condensing boiler as a boiler, this results in a special economical heating operation.

In dem zwischen dem Heizkreisverteiler 1 und dem nicht dargestellten Heizkessel gebildeten Kesselkreis ist zweckmäßig, wie an sich üblich, eine weitere Zirkulationspumpe zur Förderung des Heizmediums vorgesehen.In the boiler circuit formed between the heating circuit manifold 1 and the boiler, not shown, it is expedient, as is customary, another circulation pump for conveying the heating medium provided.

Die Figur 4 zeigt den Heizkreisverteiler 1 in einem zweiten beispielhaften Betriebszustand, in gleicher schematischer Darstellung wie in Figur 3. In dem in Figur 4 gezeigten Betriebszustand hat der erste Heizkreis für die Heizkörper einen etwa doppelt so großen Volumenstrombedarf an Heizmedium wie der zweite Heizkreis mit der Fußbodenheizung. Die Volumenströme durch die beiden Heizkreise sind also nicht mehr gleich groß. Zum Ausgleich dieser unterschiedlichen Volumenströme in den beiden Heizkreisen dient die in den Heizkreisverteiler 1 integrierte hydraulische Weiche in Form der Weichenkammer 5.The FIG. 4 shows the heating circuit manifold 1 in a second exemplary operating state, in the same schematic representation as in FIG. 3 , In the in FIG. 4 shown operating state of the first heating circuit for the radiator has about twice as large volume flow demand of heating medium as the second heating circuit with the floor heating. The volume flows through the two heating circuits are therefore no longer the same size. To compensate for these different volume flows in the two heating circuits, the integrated in the heating circuit manifold 1 hydraulic switch in the form of the switch chamber fifth

Zunächst strömt auch hier von einem Heizkessel erhitztes Heizmedium durch den Heizkesselvorlaufanschluss 51, die Weichenkammer 5, die Durchbrechung 61 und die Vorlaufkammer 2 sowie den Heizkreisvorlaufanschluss 21 in den ersten Heizkreis, der Heizkörper versorgt. Die Förderung des Heizmediums durch den ersten Heizkreis bewirkt auch hier wieder die Pumpe 91. Das aus dem ersten Heizkreis zurücklaufende Heizmedium fließt mit reduzierter Temperatur durch den Heizkreisrücklaufanschluss 42 in die Zwischenkammer 4 des Heizkreisverteilers 1. Ein Teil des Volumenstroms des durch den Heizkreisrücklaufanschluss 42 in die Zwischenkammer vier einströmenden Heizmediums, hier etwa die Hälfte davon, fließt durch den Heizkreisvorlaufanschluss 41 über ein Mischventilen 90 durch die zweite Pumpe 92 in den zweiten Heizkreis. Überschüssiges Heizmedium aus der Zwischenkammer vier, welches hier nun nicht für den zweiten Heizkreis benötigt wird, strömt durch die als Lochblech ausgeführte Zwischenplatte 17 aus dem oberen Kammerteil 40 der Zwischenkammer 4 in deren unteren Kammerteil 40'. Von dort fließt das überschüssige Heizmedium durch den Rohrstutzen 71' und dessen Öffnung 72' in den linken Teil der Weichenkammer 5.First, also heated by a boiler heating medium flows through the boiler flow connection 51, the switch chamber 5, the opening 61 and the flow chamber 2 and the heating circuit flow connection 21 in the first heating circuit, the radiator powered. The promotion of the heating medium by the first heating circuit causes here again the pump 91. The returning from the first heating medium heating medium flows at a reduced temperature through the heating circuit return port 42 into the intermediate chamber 4 of the heating circuit 1. A portion of the volume flow through the Heizkreisrücklaufanschluss 42 in the Intermediate four inflowing heating medium, here about half thereof, flows through the heating circuit flow connection 41 via a mixing valves 90 through the second pump 92 in the second heating circuit. Excess heating medium from the intermediate chamber four, which is not needed here for the second heating circuit, flows through the designed as a perforated plate intermediate plate 17 from the upper chamber portion 40 of the intermediate chamber 4 in the lower chamber part 40 '. From there, the excess heating medium flows through the pipe socket 71 'and its opening 72' in the left part of the switch chamber fifth

Das aus dem zweiten Heizkreis für die Fußbodenheizung zurückströmende Heizmedium fließt durch den Heizkreisrücklaufanschluss 32 zunächst in die Rücklaufkammer 3 und aus dieser durch die Durchbrechung 62 in die Weichenkammer 5, wo sich die beiden Teil-Volumenströme wieder zu dem gesamten Volumenstrom vereinigen und gemeinsam durch den Heizkesselrücklaufanschluss 52 zur erneuten Erhitzung dem Heizkessel zugeführt werden.The heating medium flowing back from the second heating circuit for the underfloor heating flows through the heating circuit return connection 32 first into the return chamber 3 and from there through the opening 62 into the switch chamber 5, where the two partial volume flows reunite to form the total volume flow and together through the boiler return connection 52 are fed to the boiler for reheating.

Im Betriebszustand nach Figur 4 wird vorteilhaft jedem Heizkreis der gerade benötigte Volumenstrom an Heizmedium mit der jeweils benötigten Vorlauftemperatur zugeführt; gleichzeitig bleibt im Kesselkreis der volle Volumenstrom des Heizmediums erhalten.In operation after FIG. 4 is advantageous to each heating circuit of the volume flow of heating medium just needed with the respective required flow temperature supplied; At the same time, the full volume flow of the heating medium is retained in the boiler circuit.

Figur 5 zeigt den Heizkreisverteiler 1 in einem dritten beispielhaften Betriebszustand, in gleicher schematischer Darstellung wie in den Figuren 3 und 4. Für diesen dritten Betriebszustand ist charakteristisch, dass nun der erste Heizkreis mit den Heizkörpern einen geringeren Volumenstrom an Heizmedium benötigt als der zweite Heizkreis mit der Fußbodenheizung. FIG. 5 shows the heating circuit manifold 1 in a third exemplary operating state, in the same schematic representation as in the Figures 3 and 4 , It is characteristic of this third operating state that now the first heating circuit with the radiators requires a lower volume flow of heating medium than the second heating circuit with the underfloor heating.

Auch hier strömt erhitztes Heizmedium vom Heizkessel kommend durch den Heizkesselvorlaufanschluss 51 in die Weichenkammer 5. In der Weichenkammer 5 teilt sich der Volumenstrom des Heizmediums in zwei Teil-Volumenströme. Ein erster Teil-Volumenstrom fließt durch die Durchbrechung 61 und die Vorlaufkammer 2 über den ersten Heizkreisvorlaufanschluss 21 in den ersten Heizkreis und wird mittels der Pumpe 91 durch diesen gefördert.Here, too, heated heating medium flowing from the boiler flows through the boiler feed connection 51 into the switch chamber 5. In the switch chamber 5, the volume flow of the heating medium is divided into two partial volume flows. A first partial volume flow flows through the opening 61 and the flow chamber 2 via the first heating circuit flow connection 21 into the first heating circuit and is conveyed by the pump 91 through the latter.

Ein zweiter Teil-Volumenstrom des Heizmediums fließt zunächst innerhalb der Weichenkammer 5 in Richtung zum Rohrstutzen 71 und durch dessen Öffnung 72 in diesen hinein und dann nach oben in den unteren Kammerteil 40' der Zwischenkammer 4. Weiter strömt dieser Teil-Volumenstrom durch die als Lochblech ausgeführte Zwischenplatte 17 in den oberen Kammerteil 40 der Zwischenkammer 4 und vereinigt sich dort mit dem Teil-Volumenstrom, der aus dem ersten Heizkreis durch den Heizkreisrücklaufanschluss 42 ebenfalls in den oberen Kammerteil 40 der Zwischenkammer 4 einströmt. Vereinigt bilden dann die beiden Teil-Volumenströme den vollen Volumenstrom, der hier den höheren Bedarf des zweiten Heizkreises an Heizmedium erfüllt. Dieser volle Volumenstrom an Heizmedium fließt durch den Heizkreisvorlaufanschluss 41 und das Mischventil 90 unter Förderung durch die Pumpe 92 durch den zweiten Heizkreis. Mittels des Mischventils 90 wird die Vorlauftemperatur des zweiten Heizkreises in Strömungsrichtung hinter dem Mischventil 90 auf einem gewünschten Wert, hier etwa 45 °C, eingestellt, um eine zu hohe Vorlauftemperatur im zweiten Heizkreis durch das Zuführen von unmittelbar vom Heizkessel kommendem Heizmedium zu vermeiden. Nach Durchströmen des zweiten Heizkreises fließt der gesamte Volumenstrom des Heizmediums durch den Heizkreisrücklaufanschluss 32 in die Rücklaufkammer 3 und von dieser durch die Durchbrechung 62 und den linken Endbereich der Weichenkammer 5 in den Heizkesselrücklaufanschluss 52 und dann zur erneuten Erhitzung zum Heizkessel.A second partial volume flow of the heating medium flows first within the turnout chamber 5 in the direction of the pipe stub 71 and through the opening 72 into this and then up into the lower chamber part 40 'of the intermediate chamber 4. Further, this partial volume flow flows through the as a perforated plate executed intermediate plate 17 in the upper chamber portion 40 of the intermediate chamber 4 and unites there with the partial volume flow, which also flows from the first heating circuit through the heating circuit return port 42 in the upper chamber portion 40 of the intermediate chamber 4. Combined then form the two part-volume flows the full volume flow, which meets the higher demand of the second heating circuit of heating medium here. This full volume flow of heating medium flows through the heating circuit flow connection 41 and the mixing valve 90, while being conveyed by the pump 92 through the second heating circuit. By means of the mixing valve 90, the flow temperature of the second heating circuit in the flow direction behind the mixing valve 90 to a desired value, here about 45 ° C, adjusted to avoid too high flow temperature in the second heating circuit by supplying coming directly from the boiler heating medium. After flowing through the second heating circuit, the entire volume flow of the heating medium flows through the heating circuit return port 32 in the return chamber 3 and from there through the opening 62 and the left end of the turnout chamber 5 in the boiler return port 52 and then to reheat to the boiler.

Figur 6 zeigt den Heizkreisverteiler 1 in einem vierten beispielhaften Betriebszustand, wieder in der schematischen Darstellung der Figuren 3 bis 5. Kennzeichnend für diesen vierten Betriebszustand ist, dass nun beide Heizkreise keinen Bedarf an Heizmedium haben, weil gerade keine Heizleistung benötigt wird. Bei in Betrieb befindlichem Heizkessel fließt das erhitzte Heizmedium durch den Heizkesselvorlaufanschluss 51 in die Weichenkammer 5. Im vorliegenden Fall verlässt das Heizmedium im Wesentlichen die Weichenkammer 5 nicht, sondern durchströmt diese auf ihrer vollen Länge an den beiden Rohrstutzen 71 und 71' und an den Strömungsleitwänden 18, 18' vorbei bis zum Heizkesselrücklaufanschluss 52. Ein gewisser Nebenstrom an Heizmedium kann parallel auch durch den ersten Rohrstutzen 71, die Zwischenkammer 4 und den zweiten Rohrstutzen 71' zum linken Ende der Weichenkammer 5 strömen, um dann durch den dortigen Heizkesselrücklaufanschluss 52 unmittelbar zum Heizkessel zurückzufließen. Hierdurch wird ein Takten des Heizkessels vermieden und dass Manko eines geringen Wasserinhalts heutiger moderner Heizkessel kompensiert. FIG. 6 shows the heating circuit manifold 1 in a fourth exemplary operating state, again in the schematic representation of FIGS. 3 to 5 , Characteristic of this fourth operating state is that now both heating circuits have no need for heating medium, because just no heating power is needed. When the boiler is in operation, the heated heating medium flows through the boiler inlet connection 51 into the switch chamber 5. In the present case, the heating medium does not substantially leave the switch chamber 5, but flows through it over its entire length at the two pipe connections 71 and 71 'and at the flow guide walls A certain side stream of heating medium can parallel through the first pipe socket 71, the intermediate chamber 4 and the second pipe socket 71 'to flow to the left end of the switch chamber 5, then by the local boiler return port 52 directly to Return boiler. As a result, a clocking of the boiler is avoided and that shortcoming of a low water content of today's modern boiler compensated.

Figur 7 der Zeichnung zeigt den Heizkreisverteiler 1 in einer zweiten Ausführung, oben in der Figur in schematischer Ansicht und unten in der Figur in schematischer Draufsicht. Im Unterschied zu dem zuvor beschriebenen Ausführungsbeispiel ist der Heizkreisverteiler 1 nach Figur 7 für drei Heizkreise ausgelegt, besitzt also an seiner Oberseite insgesamt drei Heizkreisvorlaufanschlüsse 21, 41 und entsprechend auch drei Heizkreisrücklaufanschlüsse 32, 42. Ein Heizkesselvorlaufanschluss 51 und ein Heizkesselrücklaufanschluss 52 sind auch hier an der Unterseite des Gehäuses 10 des Heizkreisverteilers 1 angeordnet. Der innere Aufbau des Heizkreisverteilers 1 gemäß Figur 7 entspricht dem zuvor beschriebenen Beispiel. Unterschiedlich ist, dass an die Vorlaufkammer 2 nun zwei Heizkreisvorlaufanschlüsse 21 und an die Zwischenkammer 4 nun zwei Heizkreisrücklaufanschlüsse 42 angesetzt sind. Die beiden ersten, diesen Anschlüssen zugeordneten Heizkreise werden also parallel von dem Heizmedium durchströmt und versorgen beispielsweise Heizkörper mit einer hohen Vorlauftemperatur von hier beispielsweise etwa 60 °C. Das auf eine Temperatur von beispielsweise etwa 45 °C abgekühlte Heizmedium aus den beiden ersten Heizkreisen gelangt über die beiden Heizkreisrücklaufanschlüsse 42 in die Zwischenkammer 4 und von dort vereinigt über den Heizkreisvorlaufanschluss 41 in den dritten Heizkreis, der wieder ein Fußbodenheizungskreis ist, welcher einen geringeren Vorlauftemperaturbedarf, hier von etwa 45 °C, hat. Das im dritten Heizkreis dann auf etwa 35 °C abgekühlte Heizmedium gelangt schließlich durch den Heizkreisrücklaufanschluss 32 in die Rücklaufkammer 3 und aus dieser durch die Durchbrechung 62 und den Heizkesselrücklaufanschluss 52 wieder zu dem auch hier nicht dargestellten Heizkessel zur erneuten Erhitzung. FIG. 7 The drawing shows the heating circuit manifold 1 in a second embodiment, at the top in the figure in a schematic view and at the bottom in the figure in a schematic plan view. In contrast to the embodiment described above, the heating circuit distributor 1 is after FIG. 7 designed for three heating circuits, so has at its top a total of three Heizkreisvorlaufanschlüsse 21, 41 and accordingly also three Heizkreisrücklaufanschlüsse 32, 42. A boiler inlet port 51 and a boiler return port 52 are also arranged here on the underside of the housing 10 of the heating manifold 1. The internal structure of the heating circuit manifold 1 according to FIG. 7 corresponds to the example described above. It is different that now two Heizkreisvorlaufanschlüsse 21 and to the intermediate chamber 4 now two Heizkreisrücklaufanschlüsse 42 are attached to the flow chamber 2. The two first, these connections associated heating circuits are thus flowed through in parallel by the heating medium and provide, for example, radiator with a high flow temperature of here, for example, about 60 ° C. The cooled to a temperature of, for example, about 45 ° C heating medium from the two first heating circuits passes through the two Heizkreisrücklaufanschlüsse 42 in the intermediate chamber 4 and from there via the Heizkreisvorlaufanschluss 41 in the third heating circuit, which is again a floor heating circuit, which requires a lower flow temperature , here about 45 ° C, has. This in the third heating circuit then cooled to about 35 ° C heating medium finally passes through the heating circuit return port 32 in the return chamber 3 and from this through the aperture 62 and the boiler return port 52 back to the boiler, not shown here for reheating.

Wie die Figur 7 veranschaulicht, sind die Anschlüsse 21, 32, 41, 42 in voneinander gleichen Abständen oberseitig am Heizkreisverteiler 1 angebracht. Dementsprechend sind die beiden Schottwände 19 und 19', die einerseits die Vorlaufkammer 2 und die Zwischenkammer 4 und anderseits die Zwischenkammer 4 und die Rücklaufkammer 3 voneinander trennen, gegenüber dem ersten Ausführungsbeispiel versetzt angeordnet. Die erste Schottwand 19 liegt nun zwischen dem linken Heizkreisvorlaufanschluss 21 und dem rechten Heizkreisrücklaufanschluss 42. Die zweite Schottwand 19' liegt unverändert zwischen dem Heizkreisvorlaufanschluss 41 und dem Heizkreisrücklaufanschluss 32.As the FIG. 7 illustrated, the terminals 21, 32, 41, 42 are mounted at equal intervals on the upper side of the heating circuit 1. Accordingly, the two bulkhead walls 19 and 19 ', on the one hand the flow chamber 2 and the intermediate chamber 4 and on the other hand, the intermediate chamber 4 and the return chamber 3 separate from each other, arranged offset from the first embodiment. The first bulkhead 19 now lies between the left heating circuit supply connection 21 and the right heating circuit return connection 42. The second bulkhead 19 'lies unchanged between the heating circuit supply connection 41 and the heating circuit return connection 32.

Im normalen Betrieb werden die beiden ersten Heizkreise für die Heizkörper parallel durchströmt. Diese beiden Heizkreise bilden mit dem dritten Heizkreis für die Fußbodenheizung eine Reihenschaltung. Falls die beiden ersten Heizkreise für die Heizkörper einen unterschiedlichen Volumenstrombedarf an Heizmedium haben, kann dies durch entsprechende Steuerung der jeweils zugehörigen Zirkulationspumpe 91 und 92 eingestellt werden. Falls die beiden ersten Heizkreise für die Heizkörper in der Summe einen anderen Bedarf an Heizmedium-Volumenstrom haben sollten als der dritte Heizkreis für die Fußbodenheizung, dann erfolgt über die hydraulische Weichenfunktion des Heizkreisverteilers 1 mittels Führung eines Ausgleichs-Volumenstroms an Heizmedium durch die Weichenkammer 5 ein entsprechender hydraulischer Ausgleich, wie oben schon beschrieben, auch wenn alle Heizkreise kein Heizmedium benötigen.In normal operation, the two first heating circuits for the radiator are flowed through in parallel. These two heating circuits form a series circuit with the third heating circuit for underfloor heating. If the two first heating circuits for the radiator have a different volume flow requirement of heating medium, this can be adjusted by appropriate control of the respective associated circulation pump 91 and 92. If the two first heating circuits for the radiators in the sum should have a different demand for heating medium flow rate than the third heating circuit for underfloor heating, then takes place via the hydraulic switch function of the heating circuit 1 by means of a balance volume flow of heating medium through the switch chamber 5 a corresponding hydraulic compensation, as already described above, even if all heating circuits need no heating medium.

Hinsichtlich der weiteren Bezugsziffern in Figur 7 wird auf die vorhergehende Beschreibung verwiesen.With regard to the further reference numbers in FIG. 7 Reference is made to the preceding description.

Figur 8 der Zeichnung schließlich zeigt den Heizkreisverteiler 1 in einer dritten Ausführung, wieder oben in der Figur in schematischer Ansicht und unten in der Figur in schematischer Draufsicht. In dieser Ausführung ist der Heizkreisverteiler 1 ausgelegt für den Anschluss eines ersten Heizkreises für Heizkörper, eines zweiten Heizkreises für eine Fußbodenheizung und, neu, eines dritten Heizkreises für einen Warmwasserbereiter. Der innere Aufbau des Heizkreisverteilers 1 mit dem Gehäuse 10 und den darin vorgesehenen Kammern 2, 3, 4 und 5 entspricht grundsätzlich den vorherigen Ausführungsbeispielen. Unterschiedlich ist die Anordnung der Schottwände 19 und 19', denn die in Figur 8 linke Schottwand 19' ist im Vergleich zum Beispiel nach Figur 7 nun nach rechts gerückt, nämlich in eine Position zwischen dem Heizkreisvorlaufanschluss 41 und dem rechten von zwei Heizkreisrücklaufanschlüsse 32. Somit wird die Rücklaufkammer 3 in Längsrichtung des Gehäuses 10 gesehen länger, während die Zwischenkammer 4 hier um das gleiche Maß verkürzt wird. FIG. 8 Finally, the drawing shows the heating circuit distributor 1 in a third embodiment, again at the top in the figure in a schematic view and at the bottom in the figure in a schematic plan view. In this embodiment, the heating circuit manifold 1 is designed for the connection of a first heating circuit for radiators, a second heating circuit for underfloor heating and, new, a third heating circuit for a Water heaters. The internal structure of the heating circuit distributor 1 with the housing 10 and the chambers 2, 3, 4 and 5 provided therein corresponds in principle to the previous exemplary embodiments. Different is the arrangement of the bulkhead walls 19 and 19 ', because the in FIG. 8 left bulkhead 19 'is compared to for example after FIG. 7 Now moved to the right, namely in a position between the heating circuit flow connection 41 and the right of two Heizkreisrücklaufanschlüsse 32. Thus, the return chamber 3 is seen in the longitudinal direction of the housing 10 longer, while the intermediate chamber 4 is shortened here by the same amount.

Im normalen Betrieb des Heizkreisverteilers 1 strömt beispielsweise auf etwa 60 °C erhitztes Heizmedium wieder von einem Heizkessel kommend durch den Heizkesselvorlaufanschluss 51 in die Weichenkammer 5 und aus dieser unmittelbar weiter durch die Durchbrechung 61 in die Vorlaufkammer 2. Dort teilt sich der Volumenstrom des Heizmediums in zwei Teil-Volumenströme, die durch die beiden Heizkreisvorlaufanschlüsse 21 in zwei verschiedenen Heizkreise, nämlich einen Heizkreis mit Heizkörpern und einen Heizkreis mit einem Warmwasserbereiter, strömen. Die Förderung des Heizmediums durch diese beiden Heizkreise erfolgt wieder mittels je einer Zirkulationspumpe 91 und 92.In normal operation of the heating circuit 1 flows, for example heated to about 60 ° C heating medium again coming from a boiler through the boiler flow connection 51 into the switch chamber 5 and from this immediately further through the opening 61 in the flow chamber 2. There, the volume flow of the heating medium in two partial volume flows, which flow through the two Heizkreisvorlaufanschlüsse 21 in two different heating circuits, namely a heating circuit with radiators and a heating circuit with a water heater. The promotion of the heating medium through these two heating circuits is again by means of a respective circulation pump 91 and 92.

Aus dem Heizkreis mit den Heizkörpern fließt das Heizmedium, auf eine Temperatur von beispielsweise etwa 45 °C abgekühlt, durch den Heizkreisrücklaufanschluss 42 in die Zwischenkammer 4. Im Warmwasserbereiter wird das Heizmedium von seiner Vorlauftemperatur weiter abgekühlt als im Heizkreis mit den Heizkörpern, hier beispielsweise auf eine Temperatur von etwa 35 °C, und wird deshalb über den Heizkreisrücklaufanschluss 32 nicht der Zwischenkammer 4, sondern direkt der Rücklaufkammer 3 zugeführt.From the heating circuit with the radiators, the heating medium flows, cooled to a temperature of, for example, about 45 ° C, through the Heizkreisrücklaufanschluss 42 into the intermediate chamber 4. In the water heater, the heating medium of its flow temperature is further cooled than in the heating circuit with the radiators, here, for example a temperature of about 35 ° C, and is therefore not supplied to the intermediate chamber 4 via the heating circuit return connection 32, but directly to the return chamber 3.

Der Heizkreis für die Fußbodenheizung wird über den Heizkreisvorlaufanschluss 41 mit Heizmedium aus der Zwischenkammer 4 versorgt, wobei die Zirkulation hier mittels der Pumpe 93 bewirkt wird. Über das Mischventil 90 kann dem Vorlauf der Fußbodenheizung Heizmedium aus deren Rücklauf bei Bedarf zugemischt werden. Das aus diesem Heizkreis zurückkehrende Heizmedium gelangt durch den zweiten Heizkreisrücklaufanschluss 32 ebenfalls in die Rücklaufkammer 3. Dort werden die Teil-Volumenströme des Heizmediums wieder zu dem vollen Volumenstrom vereinigt und dieser wird dann durch die Durchbrechung 62, durch den linken Endbereich der Weichenkammer 5 und den Heizkesselrücklaufanschluss 52 dem Heizkessel zur erneuten Erhitzung zugeführt.The heating circuit for underfloor heating is supplied via the heating circuit flow connection 41 with heating medium from the intermediate chamber 4, wherein the circulation is effected here by means of the pump 93. About the mixing valve 90, the flow of the underfloor heating medium from the return can be mixed if necessary. The heating medium returning from this heating circuit also passes through the second heating circuit return connection 32 into the return chamber 3. There, the partial volume flows of the heating medium are combined again to the full volume flow and this is then through the opening 62, through the left end the switch chamber 5 and the boiler return port 52 are fed to the boiler for reheating.

Auch in dieser Ausführung des Heizkreisverteilers 1 werden im Falle von unterschiedlichem oder schwankendem Volumenstrombedarf an Heizmedium in den verschiedenen Heizkreisen die Volumenstromdifferenzen mittels der hydraulischen Funktion der Weichenkammer 5 des Heizkreisverteilers 1 ausgeglichen, indem Ausgleichsvolumenströme des Heizmediums durch die Weichenkammer 5 geleitet werden. Dies gilt auch hier für den Extremfall, dass keiner der Heizkreise einen Bedarf an Heizmedium hat.In this embodiment of the heating circuit manifold 1, the volume flow differences by means of the hydraulic function of the switch chamber 5 of the heating circuit 1 are compensated in the case of varying or fluctuating volume flow requirement of heating medium in the various heating circuits by equalizing volume flows of the heating medium are passed through the switch chamber 5. This also applies here in the extreme case that none of the heating circuits has a need for heating medium.
