Die
Als nachteilig wird bei dem vorstehend genannten Stand der Technik angesehen, dass es bei einer Ausführung mit mehr als zwei Temperaturzonen zu einer unerwünschten gegenseitigen Störung der Temperaturzonen kommt, wenn eine Ausgleichsströmung von einer ersten Temperaturzone in eine nicht unmittelbar benachbarte, zum Beispiel dritte Temperaturzone auftritt. Die Störung wird dadurch verursacht, dass eine derartige Ausgleichsströmung auf ihrem Weg von der ersten Temperaturzone zu der dritten Temperaturzone durch die zweite Temperaturzone hindurchströmt, welche dadurch in ihrer Temperatur unerwünscht verändert wird.A disadvantage is considered in the above-mentioned prior art that in an embodiment with more than two temperature zones to an undesirable mutual interference of the temperature zones comes when a compensation flow from a first temperature zone into a not immediately adjacent, For example, third temperature zone occurs. The disturbance is caused by the fact that such a compensating flow flows on its way from the first temperature zone to the third temperature zone through the second temperature zone, which is thereby undesirably changed in its temperature.
Für die vorliegende Erfindung stellt sich daher die Aufgabe, eine hydraulische Weiche der eingangs genannten Art zu schaffen, die die angegebenen Nachteile vermeidet und bei der insbesondere Ausgleichsströmungen von einer Temperaturzone in eine nicht unmittelbar benachbarte andere Temperaturzone keine störenden Auswirkungen für die dazwischen liegende Temperaturzone oder die dazwischen liegenden Temperaturzonen hat.For the present invention, therefore, the object is to provide a hydraulic switch of the type mentioned, which avoids the disadvantages mentioned and in the particular compensation flows from a temperature zone in a not immediately adjacent other temperature zone no disturbing effects for the intermediate temperature zone or the has intermediate temperature zones.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit einer hydraulischen Weiche der eingangs genannten Art, die dadurch gekennzeichnet ist, dass zumindest über den Abstand A oder die Strömungsöffnung hinweg ein Mantelrohr als Trennelement angeordnet ist, welches die Rohrstutzen des jeweiligen Paares mit einem radialen Abstand umgibt.The solution of this object is achieved according to the invention with a hydraulic switch of the type mentioned, which is characterized in that at least over the distance A or the flow opening a jacket tube is arranged as a separating element which surrounds the pipe socket of the respective pair with a radial distance.
Bei der erfindungsgemäßen hydraulischen Weiche werden vorteilhaft gegenseitige Störungen der Temperaturzonen im Falle von eine oder mehrere Temperaturzonen "überspringenden" Ausgleichsströmungen zuverlässig vermieden, weil für derartige Ausgleichsströmungen eigene Strömungswege in Behälter der Weiche vorgesehen sind, die nicht durch die eigentlichen Temperaturzonen verlaufen, sondern diese umgehen. Da die Trägermedium-Strömungswege zur Umgehung der Trägermedium-Temperaturzonen im Inneren des Behälters vorgesehen sind, benötigt der Behälter keinen größeren Platzbedarf als der Behälter einer herkömmlichen hydraulischen Weiche.In the hydraulic switch according to the invention mutual disturbances of the temperature zones in the case of one or more temperature zones "skipping" compensating flows are reliably avoided, because for such compensating flows own flow paths are provided in containers of the switch, which do not pass through the actual temperature zones, but handle them. Since the carrier medium flow paths are provided for bypassing the carrier medium temperature zones inside the container, the container does not require more space than the container of a conventional hydraulic separator.
Dadurch, dass jeder Trägermedium-Temperaturzone ein Paar von zwei einander gegenüberliegend in das Innere des Behälters mündenden, mit den Anschlüssen verbundenen, miteinander fluchtenden Rohrstutzen zugeordnet ist und dass die zwei Rohrstutzen eines Paares entweder einen Abstand voneinander aufweisende freie Enden haben oder als ein durchgehendes Rohr mit mindestens einer Strömungsöffnung zum Inneren des Behälters ausgeführt sind, werden ungünstige Strömungsturbulenzen vermieden oder zumindest gering gehalten. Außerdem wird hierdurch der mechanische Aufbau der hydraulischen Weiche vorteilhaft einfach gehalten.Characterized in that each carrier medium temperature zone is associated with a pair of two mutually opposite in the interior of the container, connected to the terminals, aligned pipe sockets and that the two pipe sockets of a pair have either a spaced free ends or as a continuous tube are designed with at least one flow opening to the interior of the container, unfavorable flow turbulence can be avoided or at least kept low. In addition, will As a result, the mechanical structure of the hydraulic switch advantageously kept simple.
Erfindungsgemäß ist außerdem zumindest über den Abstand A oder die Strömungsöffnung hinweg ein Mantelrohr als Trennelement angeordnet, welches die Rohrstutzen des jeweiligen Paares mit einem radialen Abstand umgibt. Hierbei bildet das Innere des Mantelrohres die jeweilige Temperaturzone, während außerhalb des Mantelrohres Raum für den die Temperaturzone umgehenden Trägermedium-Strömungsweg verbleibt. Zu diesem Zweck hat das Mantelrohr zumindest in seiner radialen horizontalen Richtung Abstand von einer inneren Oberfläche des Behälters; zusätzlich kann das Mantelrohr auch in seiner Axialrichtung Abstand von der inneren Oberfläche des Behälters haben. Vorteilhaft ist bei dieser Ausführung der hydraulischen Weiche auch, dass das Trennelement einteilig ausgeführt sein kann, was den Fertigungsaufwand niedrig hält.According to the invention, at least over the distance A or the flow opening a jacket tube is arranged as a separating element which surrounds the pipe socket of the respective pair with a radial distance. In this case, the interior of the jacket tube forms the respective temperature zone, while leaving room outside the jacket tube for the carrier medium flow path surrounding the temperature zone. For this purpose, the jacket tube, at least in its radial horizontal direction, is spaced from an inner surface of the container; In addition, the jacket tube may also be spaced from the inner surface of the container in its axial direction. It is advantageous in this embodiment of the hydraulic switch also that the separating element can be made in one piece, which keeps the production cost low.
Um auf technisch einfache Art und Weise die bedarfsweise nötigen Ausgleichsströmungen des Trägermediums zu ermöglichen, wird weiter vorgeschlagen, dass das das Trennelement bildende Mantelrohr zur Bildung des Trägermedium-Strömungsdurchlasses ein- oder beidseitig stirnseitig zum Behälterinneren offen und/oder mit einer oder mehreren Durchbrechungen in seinem Umfang ausgeführt ist.To allow in a technically simple manner, where necessary, necessary equalizing flows of the support medium, it is further proposed that the partition forming the jacket tube to form the carrier medium flow passage one or both sides frontally open to the container interior and / or with one or more openings in his Scope is executed.
Als technische Alternative oder als zusätzliches Merkmal zu dem Mantelrohr als Trennelement schlägt die Erfindung in einer zweiten, alternativen oder zusätzlichen erfindungsgemäßen Lösung vor, dass jeweils eine Trägermedium-Temperaturzone im Behälter durch ein Paar aus je einer oberen und unteren Trennscheibe als Trennelement begrenzt ist. Auch in dieser Ausführung werden zum einen voneinander getrennte Trägermedium-Temperaturzonen im Behälter gebildet und gleichzeitig Strömungswege für Ausgleichsströmungen zur Verfügung gestellt.As a technical alternative or as an additional feature to the jacket tube as a separating element, the invention proposes in a second, alternative or additional solution according to the invention that in each case a carrier medium temperature zone in the container is limited by a pair of upper and lower cutting disc as a separating element. Also in this embodiment, for a separate carrier medium temperature zones are formed in the container and at the same time provided flow paths for compensating flows available.
Eine konkrete Weiterbildung sieht diesbezüglich vor, dass jede das Trennelement bildende Trennscheibe zur Bildung des Trägermedium-Strömungsdurchlasses mit einer inneren Oberfläche der Umfangswand des Behälters einen Ringspalt bildet. Der Ringspalt beziehungsweise eine Anordnung mehrerer Ringspalt bildet dabei den Strömungsweg für Ausgleichsströmungen, wodurch die Ausgleichsströmungen radial außen und parallel zur inneren Oberfläche des Behälters verlaufen. Auch bei dieser Gestaltung werden durch die Ausgleichsströmungen verursachte Störungen der Temperaturzonen vermieden.A concrete development in this regard provides that each separating disk forming the separating element forms an annular gap with an inner surface of the peripheral wall of the container to form the carrier medium flow passage. The annular gap or an arrangement of a plurality of annular gap forms the flow path for compensating flows, whereby the compensating flows extend radially outward and parallel to the inner surface of the container. Also at This design avoids disturbances of the temperature zones caused by the compensation flows.
Zur Begünstigung der gewünschten Temperaturschichtung der Temperaturzonen im Behälter und zur Begrenzung der für die Aufstellung des Behälters benötigten Grundfläche hat der Behälter bevorzugt die Grundform eines im Betrieb der Weiche stehenden, länglichen Zylinders oder Quaders.To favor the desired temperature stratification of the temperature zones in the container and to limit the space required to set up the container, the container preferably has the basic shape of an elongate cylinder or cuboid that is in operation during the switch.
Bei dem eingangs zitierten Stand der Technik sind die Anschlüsse am Gehäuse über dessen Umfang verteilt vorgesehen, was nachteilig zu einem unübersichtlichen Anschlussbild und zu einer komplizierten Leitungsführung außerhalb des Behälters führt. Um hier eine übersichtlichere Anordnung mit geringerer Wahrscheinlichkeit von Anschlussfehlern zu erzielen, sind erfindungsgemäß bevorzugt die Anschlüsse entlang von zwei vertikalen Linien übereinander an dem Behälter angeordnet. Eine noch bessere Übersichtlichkeit und Einfachheit der Anschlüsse ergibt sich dann, wenn, wie weiter bevorzugt ist, entlang der einen vertikalen Linien die Trägermedium zuführenden Anschlüsse und auf der anderen vertikalen Linie die Trägermedium abführenden Anschlüsse angeordnet sind.In the cited prior art, the terminals are provided on the housing distributed over the circumference, which leads adversely to a confusing connection diagram and a complicated wiring outside the container. In order to achieve a clearer arrangement with less likelihood of connection errors here, according to the invention, the connections are preferably arranged one above the other along two vertical lines on the container. An even better clarity and simplicity of the connections is obtained if, as is more preferable, along one vertical lines, the carrier medium supplying terminals and on the other vertical line, the carrier medium discharging terminals are arranged.
Für die weiter oben schon erwähnte Strömungsöffnung ist bevorzugt vorgesehen, dass diese durch eine Anordnung von in Umfangsrichtung und Längsrichtung des jeweiligen durchgehenden Rohres verteilt angeordneten Durchbrüchen gebildet ist. Solche Durchbrüche lassen sich leicht zum Beispiel durch Bohren oder Fräsen oder Brennen erzeugen und erfordern daher bei ihrer Herstellung keinen großen Aufwand.For the above-mentioned flow opening is preferably provided that this is formed by an arrangement of distributed circumferentially and longitudinally of the respective continuous tube arranged openings. Such breakthroughs can be easily produced for example by drilling or milling or burning and therefore require little effort in their preparation.
Eine Maßnahme zur Begrenzung des Aufwandes beim Anschließen von zu- und abführenden Leitungen an die hydraulische Weiche besteht darin, dass zweckmäßig die Anschlüsse in ihrem außerhalb des Behälters liegenden Teil als nach radial außen weisende Rohrabschnitte mit je einem in einer vertikalen Ebene liegenden Anschlussende, vorzugsweise Anschlussflansch, ausgebildet sind.A measure for limiting the effort when connecting incoming and outgoing lines to the hydraulic switch is that expedient the connections in their lying outside the container part as pointing radially outward pipe sections, each with a lying in a vertical plane connection end, preferably connection flange , are formed.
Schließlich ist erfindungsgemäß bevorzugt vorgesehen, dass der Behälter im Betrieb einen Schichtenspeicher mit darin temperaturabhängig geschichtetem Trägermedium bildet, dass die Trägermedium zuführenden Anschlüsse jeweils mit derjenigen Trägermedium-Temperaturzone verbunden sind, die in einer der jeweiligen Temperatur des im Betrieb zufließenden Trägermediums entsprechenden Höhe im Behälter angeordnet ist, und dass die Trägermedium abführenden Anschlüsse jeweils mit derjenigen Trägermedium-Temperaturzone verbunden sind, die in einer der im Betrieb jeweils benötigten Temperatur des abfließenden Trägermediums entsprechenden Höhe im Behälter angeordnet ist. Die erfindungsgemäße hydraulische Weiche erhält so zusätzlich die Funktion eines Schichtenspeichers für das Trägermedium, wodurch eine besonders hohe Energieeffizienz erzielt wird, insbesondere wenn Wärme- oder Kältequellen mit unterschiedlichem Temperaturangebot und/ oder Heiz- oder Kühlkreise mit unterschiedlichem Temperaturbedarf hydraulisch miteinander zu verbinden sind.Finally, the invention preferably provides that the container in operation forms a stratified storage tank with a temperature-dependent stratified carrier medium, that the carrier medium supplying connections are each connected to that carrier medium temperature zone, in one of the respective Temperature is arranged in the container corresponding to the temperature of the incoming carrier medium during operation, and that the carrier medium discharging terminals are each connected to that carrier medium temperature zone which is arranged in one of the respective operating temperature required in the outflowing carrier medium height in the container. The inventive hydraulic switch thus additionally receives the function of a stratified storage for the carrier medium, whereby a particularly high energy efficiency is achieved, especially when heat or cooling sources with different temperature range and / or heating or cooling circuits with different temperature requirements are hydraulically connected to each other.

Um die Rohrstutzen 3.2, 4.2 herum ist mit Abstand und konzentrisch zu diesen ein hohlzylindrisches Mantelrohr als Trennelement 5 angeordnet. Das Trennelement 5 hat dabei in horizontaler Richtung gesehen sowohl in seiner Radialrichtung als auch in seiner Axialrichtung Abstand von einer inneren Oberfläche der Umfangswand 12 des Behälters 10. In gleicher Weise sind die Anschlüsse 30.4 und 40.4 mit miteinander zu einem durchgehenden Rohr verbundenen Rohrstutzen 3.4 und 4.4 mit einem Strömungsdurchlass 21 und mit einem gleichen Trennelement 5 ausgeführt.The second port 30.2, seen from above, on one side and the second port 40.2 arranged at the same height on the other side are designed as mutually aligned and connected pipe sockets 3.2, 4.2, ie to one another connected through the continuous tube, which has a

In Inneren 11 des Behälters 10 befinden sich, entsprechend der Zahl der Paare von Anschlussstutzen 30.1 - 30.5 und 40.1 - 40.5 fünf Temperaturzonen 2.1 - 2.5, wobei das Trägermedium in der Temperaturzone 2.1 die höchste Temperatur und in der Temperaturzone 2.5 die niedrigste Temperatur hat. Zwischen je zwei einander benachbarten Temperaturzonen 2.2 und 2.3 bzw. 2.3 und 2.4 liegen Zwischenbereiche 20, die von den Temperaturzonen 2.2, 2.3 und 2.4 durch die jeweiligen Trennelemente 5 getrennt sind. Alle Temperaturzonen 2.1 - 2.5 und die Zwischenbereiche 20 stehen aber miteinander in Strömungsverbindung, da die Trennelemente 5 jeweils mindestens einen, im gezeichneten Beispiel jeweils zwei stirnseitige Trägermedium-Strömungsdurchlässe 50 aufweisen und weil radial und axial außen von den Trennelementen 5 in Inneren 11 des Behälters 10 Strömungswege für das Trägermedium freigehalten sind.In the interior 11 of the

Die Erwärmung des Trägermediums erfolgt in Wärmequellen, wie Heizkessel, Wärmepumpe oder Solarkollektor; auch mit relativ hoher Temperatur aus seinem Heizkreis zurückfließendes Trägermedium kann, entsprechend seiner konkreten Temperatur, über einen der Anschlüsse 30.1 - 30.5 dem Inneren 11 des Behälters 10 zugeführt werden.When using the
Über die Anschlüsse 40.1 - 40.5 wird warmes Trägermedium mit unterschiedlichen, passenden Temperaturen verschiedenen Verwendungskreisen, wie Heizkreisen für Fußbodenheizung, Heizkörper oder Brauchwassererwärmung, zugeführt. Entsprechend seiner Temperatur liegt das Trägermedium in Inneren 11 des Behälters 10 temperaturmäßig geschichtet vor, wobei in der Trägermedium-Temperaturzone 2.1 oben im Behälter 10 das Trägermedium die höchste Temperatur und in der Trägermedium-Temperaturzonen 2.5 unten im Behälter 10 das Trägermedium die niedrigste Temperatur hat. Zwischen je zwei einander benachbarten Temperaturzonen 2.2 und 2.3 sowie 2.3 und 2.4 liegt jeweils einer der Zwischenbereiche 20 in Inneren 11 des Behälters 10, wobei die Zwischenbereiche 20 jeweils durch eines der Trennelemente 5 von den Temperaturzonen 2.2 - 2.4 getrennt sind, ohne eine strömungsmäßige Verbindung zu verhindern.About the ports 40.1 - 40.5 warm carrier medium with different, matching temperatures various uses, such as heating circuits for underfloor heating, radiators or domestic water heating supplied.
