Description

Die Erfindung betrifft einen Wärmeerzeuger für Heizzwecke und Warmwasserbereitung mit einem Brennwertgerät, einem Wärmetauscher und Steuer- und Regeleinrichtungen, die in einem Gerätegehäuse untergebracht sind, auf dessen Rückwand Geräte-Anschlüsse für Anschluss- und Verbindungs-Rohrleitungen vorgesehen sind.The invention relates to a heat generator for heating purposes and water heating with a condensing boiler, a heat exchanger and control and regulating devices, which are housed in a device housing, on the back wall device connections are provided for connection and connection pipelines.

Stand der TechnikState of the art

Bei diesen bekannten Wärmeerzeugern (vergleiche beispielweise DE 1454714) mit der rückseitigen Installation der Anschluss- und Verbindungsleitungen bereitet die Installation immer wieder Schwierigkeiten am Einsatzort. Vielfach sind die Raumverhältnisse zum Aufstellen des Wärmeerzeugers so ungünstig, dass die Anschluss- und Verbindungsleitungen nur von einer bestimmten Seite aus an die Geräte-Anschlüsse herangeführt werden können. Erschwerend kommt hinzu, dass sich dies von Einsatzort zu Einsatzort verändern kann. Dies erfordert in der Regel an jedem Einsatzort bestimmte Vorkehrungen und Anpassungsmaßnahmen, was die Montage und Installation des Wärmeerzeugers am Einsatzort nicht nur kompliziert, sondern auch verteuert.In these known heat generators (see, for example, DE 1454714) with the back-side installation of the connecting and connecting cables, the installation always causes difficulties at the place of use. In many cases, the spatial conditions for setting up the heat generator are so unfavorable that the connecting and connecting lines can only be brought from a specific page to the device ports. To make matters worse, this can change from site to site. This usually requires certain precautions and adjustments at each site, which not only complicates the assembly and installation of the heat generator at the site, but also more expensive.

Es ist Aufgabe der Erfindung, einen Wärmeerzeuger der eingangs erwähnten Art so auszugestalten, dass er wahlweise in zwei Richtungen anschließbar ist und dazu nur vorgegebene Montageelemente erfordert, die die Anpassung der Anschlussmöglichkeiten auf einfache Weise sicherstellen.It is an object of the invention to provide a heat generator of the type mentioned in such a way that it is selectively connectable in two directions and requires only predetermined mounting elements that ensure the adaptation of the connection options in a simple manner.

Vorteile der ErfindungAdvantages of the invention

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass ein Teil der Geräte-Anschlüsse auf der vertikalen Mittelachse der Rückwand angeordnet und mittels abgebogener Rohrstücke in den einen oder anderen vertikalen Randbereich der Rückwand geführt sind, dass Paare von Geräte-Anschlüssen auf der Rückwand angeordnet sind, wobei diese in gleichem Abstand zu den beiden zugekehrten vertikalen Seiten des Gerätegehäuses stehen, dass diese Paare von Geräte-Anschlüssen mittels eines kurzen und eines langen Rohrstückes zu demselben Randbereich der Rückwand wie die an den mittleren Geräte-Anschlüssen angeschlossenen Rohrstücke geführt sind, und dass die freien Enden aller Rohrstücke in einer Halteleiste so gehalten sind, dass sie mit Installationsanschlüssen in einer gemeinsamen Installationsebene liegen.This object is achieved according to the invention in that a part of the device connections are arranged on the vertical center axis of the rear wall and guided by bent pipe sections in one or the other vertical edge region of the rear wall, that pairs of device terminals are arranged on the rear wall , These are at equal distance from the two facing vertical sides of the device housing that these pairs of device connections are guided by means of a short and a long piece of pipe to the same edge region of the rear wall as the connected to the middle device terminals pipe sections, and that the free ends of all pipe sections are held in a retaining strip so that they lie with installation connections in a common installation level.

Die Anschlussleiste kann wahlweise in dem einen oder anderen vertikalen Randbereich des Gerätegehäuses angebracht werden. Die gleichen Rohrstücke können von mittleren Geräte-Anschlüssen nach links oder rechts zu den Randbereichen geführt und mit ihren freien Enden in der Halteleiste gehalten werden. Den Geräte-Anschlüssen zugekehrt wird die wahlweise Ausrichtung der Rohrstücke dadurch erleichtert, dass die Geräte-Anschlüsse als Schraubanschlüsse ausgebildet sind und dass die den Schraubanschlüssen zugekehrten Enden der Rohrstücke mit Überwurfmuttern und Dichtungsflanschen versehen sind. Dies gilt auch für die unterschiedlich langen, den Geräte-Anschlusspaaren in den Randbereichen der Rückwand.The terminal block can be optionally mounted in one or the other vertical edge region of the device housing. The same pieces of pipe can be led from the middle device connections to the left or right to the edge areas and held with their free ends in the retaining strip. Turning the device connections facing the optional alignment of the pipe sections is facilitated by the fact that the device connections are designed as screw connections and that the screw connections facing the ends of the pipe sections are provided with union nuts and sealing flanges. This also applies to the differently long, the device connection pairs in the edge regions of the rear wall.

In der Regel ist eine Ausgestaltung ausreichend, die dadurch gekennzeichnet ist, dass die Geräte-Anschlüsse zwei Geräte-Anschlüsse auf der Mittelachse der Rückwand und je einen Geräte-Anschluss in den vertikalen Randbereichen der Rückwand umfassen und dass ein Satz von Rohrstücken zwei gleiche Rohrstücke mit einer Länge, die etwa der halben Breite des Gerätegehäuses entspricht, einem kurzen Rohrstück mit einer Länge vom Randbereich bis zur zugekehrten Installationsebene und einem langen Rohrstück mit einer Länge von Randbereich zur gegenüberliegenden Installationsebene aufweist.In general, an embodiment is sufficient, which is characterized in that the device connections comprise two device connections on the central axis of the rear wall and a respective device port in the vertical edge regions of the rear wall and that a set of pipe sections with two equal pieces of pipe a length corresponding to about half the width of the device housing, a short length of pipe having a length from the edge region to the facing installation level and a long length of pipe with a length of edge region to the opposite installation level.

Es wird immer sichergestellt, dass in der Installationsebene sowohl auf der einen oder anderen Anschlussseite des Wärmeerzeugers alle Installationsanschlüsse der Rohrstücke in einer vertikalen Installationsebene liegen.It is always ensured that in the installation level, both on one or the other connection side of the heat generator all installation connections of the pipe sections are in a vertical installation level.

Damit die Geräte-Anschlüsse genügend Platz für die zugeordneten Rohrstücke, Geräte-Anschlüsse und Installationsanschlüsse bieten, ist nach einer Ausgestaltung vorgesehen, dass die Paare von Geräte-Anschlüssen horizontal gegeneinander versetzt sind und sich mit den Geräte-Anschlüssen und den angeschlossenen Rohrstücken und ihren Installationsanschlüssen vertikal nicht überlappen.So that the device connections provide sufficient space for the associated pipe sections, device connections and installation connections, according to one embodiment, the pairs of device connections are horizontally offset from one another and connected to the device connections and the connected pipe sections and their installation connections do not overlap vertically.

Die Installationsanschlüsse der Rohrstücke sind als Schraubanschlüsse ausgebildet. Die anzuschließenden Rohrleitungen können dann mit Dichtungsflansch und Überwurfmutter versehen mit den Installationsanschlüssen des Wärmeerzeugers durch Verschrauben verbunden werden. Die Anschlussrichtung am Wärmeerzeuger ist leicht veränderbar, da nur die Anschlussleiste an dem anderen Randbereich des Gerätegehäuses anzubringen und die Rohrstücke um 180° zu verdrehen oder bei den Geräte-Anschlusspaaren zu vertauschen und zu verdrehen sind.The installation connections of the pipe sections are designed as screw connections. The pipes to be connected can then be connected to the installation connections of the heat generator by screwing provided with sealing flange and union nut. The connection direction at the heat generator can be easily changed, since only the terminal strip must be attached to the other edge area of the device housing and the pipe sections rotated by 180 ° or swapped and twisted at the device connection pairs.

Damit die Installation und auch die Änderung der Anschlussrichtung nicht behindert wird, sieht eine weitere Ausgestaltung vor, dass die Rohrstücke rechtwinklig abgebogen sind und dass die den Geräte-Anschlüssen zugekehrten Schenkel einheitlich ausgebildet sind und eine Länge aufweisen, die einen definierten Installationsabstand zur Rückwand des Gerätegehäuses sicherstellt.Thus, the installation and also the change of the connection direction is not hindered, provides a further embodiment that the pipe sections are bent at right angles and that the device terminals facing legs are uniform and have a length which has a defined installation distance to the rear wall of the device housing ensures.

Ist nach einer Weiterbildung vorgesehen, dass die Halteleiste mindestens eine weitere Aufnahme für eine Zusatz-Rohrleitung mit Installations- oder Verbindungsanschluss aufweist, dann können auch weitere Rohrleitungen als Anschluss- oder Verbindungsleitungen von und zu anderen Geräten, wie einem Schichtladespeicher an der Halteleiste in dieselbe Installationsebene gebracht werden. So kann nach einer Erweiterung vorgesehen sein, dass der Wärmeerzeuger auf ein als Standgerät ausgebildetes Speicher-Gerät mit Schichtladespeicher aufsetzbar und mit diesem frontseitig bündig verbindbar ist. Darüber hinaus ist dann vorgesehen, dass zumindest ein Teil der Geräte-Anschlüsse des Speicher-Gerätes mittels Rohrleitungen zur Halteleiste am Wärmeerzeuger geführt ist und dass diese Rohrleitungen in der Installationsebene mit Installationsanschlüssen enden.Is provided according to a development that the retaining strip has at least one further receptacle for an additional pipeline with installation or connection port, then other pipes can be used as connection or connecting lines to and from other devices, such as Schichtladespeicher be brought to the retaining strip in the same installation level. Thus, after an extension can be provided that the heat generator can be placed on a trained as a standalone storage device with stratified storage and flush with this front side. In addition, it is then provided that at least a part of the device connections of the storage device is guided by means of pipes to the retaining strip on the heat generator and that these pipes terminate in the installation level with installation connections.

Die Wärmeerzeuger werden vielfach in einheitlichen Gerätegehäusen untergebracht, jedoch auf unterschiedliche Heizleistungen oder Funktionen ausgelegt. Bei diesem Vorgehen ist es von Vorteil, wenn die Ausgestaltung so vorgenommen wird, dass auf unterschiedliche Heizleistung ausgelegte Wärmeerzeuger ein einheitliches Anschlussfeld mit Geräte-Anschlüssen und Rohrstücken aufweisen.The heat generators are often housed in unitary device housings, but designed for different heating capacities or functions. In this approach, it is advantageous if the design is made so that heat generators designed for different heating power have a uniform connection field with device connections and pipe sections.

Ausführungsbeispielembodiment

Da es bei der vorliegenden Erfindung auf die Anschlusstechnik des Wärmeerzeugers, d.h. um die Installation am Einsatzort, ankommt, ist die Ausrüstung des Wärmeerzeugers nicht von Bedeutung. Im Gerätegehäuse sind in der Regel untergebracht ein Brennwertgerät, ein Wärmetauscher, die Steuer- und Regeleinrichtungen und ein Gebläse, eine Gasarmatur, eine Zündeinrichtung, eine Heizungspumpe für den Heizkreis des Wärmetauschers usw. Dem Wärmeerzeuger ist Gas und Wasser zuzuführen, denn der Wärmetauscher kann als Wasser-Wasser-Wärmetauscher ausgebildet sein.Since in the present invention, the connection technology of the heat generator, ie the installation on site, arrives, the equipment of the heat generator is not important. In the device housing are usually housed a condensing boiler, a heat exchanger, the control and regulating devices and a blower, a gas valve, an ignition device, a heating pump for the heating circuit of the heat exchanger, etc. The heat generator is gas and water supply, because the heat exchanger can Be formed water-water heat exchanger.

Der Wärmeerzeuger 10 hat im unteren Teil der Rückwand 12 eine entsprechende Anzahl von Geräte-Anschlüssen 13 bis 16, die zur Zufuhr von Gas und Wasser nutzbar sind. Zudem können auch Geräte-Anschlüsse für den Anschluss eines Schichtladespeichers vorgesehen sein. Die Geräte-Anschlüsse 13 bis 16 bilden ein definiertes Anschlussfeld, das sich bei anderen Wärmeerzeugern 10 mit unterschiedlicher Heizleistung oder Funktion vorzugsweise identisch wiederholt.The heat generator 10 has in the lower part of the rear wall 12, a corresponding number of device ports 13 to 16, which are available for the supply of gas and water. In addition, device connections can also be provided for the connection of a stratified charge storage. The device connections 13 to 16 form a defined connection field, which is preferably identical in the case of other heat generators 10 with different heating power or function.

Die Geräte-Anschlüsse 13 und 14 liegen auf der vertikalen Mittelachse der Rückwand 12 und können, wie die Fig. 1 und 2 zeigen, wahlweise nach rechts oder links weitergeführt werden. Dabei ist an der vertikalen Trägerleiste 31 oder 32 eine Halteleiste 30 angebracht. Die Geräte-Anschlüsse 13 und 14 sind als Schraubanschlüsse ausgebildet und werden mit gebogenen Rohrstücken 20 und 21 verbunden. Die den Geräte-Anschlüssen 13 und 14 zugekehrten kurzen Schenkel der Rohrstücke 20 und 21 sind mit Dichtungsflanschen und Überwurfmuttern versehen, so dass sie mit den Geräte-Anschlüssen 13 und 14 verschraubt werden können. Dabei sind die beiden Rohrstücke 13 und 14 identisch und weisen eine Länge auf, die in etwa der halben Breite des Wärmeerzeugers 10 entspricht. Die Rohrstücke 13 und 14 laufen an den freien, in der Halteleiste 30 gehaltenen Enden in Installationsanschlüsse 24 und 25 aus, die in einer vertikalen Installationsebene liegen. Je nach Ausrichtung wird der Anschluss nach links (Fig. 1) oder nach rechts (Fig. 2) verlegt.The device terminals 13 and 14 are located on the vertical center axis of the rear wall 12 and can, as shown in FIGS. 1 and 2, optionally be continued to the right or left. In this case, a retaining strip 30 is attached to the vertical support bar 31 or 32. The device terminals 13 and 14 are formed as screw terminals and are connected to bent pipe sections 20 and 21. The device terminals 13 and 14 facing the short legs of the pipe sections 20 and 21 are provided with sealing flanges and union nuts, so that they can be screwed to the device terminals 13 and 14. The two pipe sections 13 and 14 are identical and have a length which corresponds approximately to half the width of the heat generator 10. The pipe sections 13 and 14 extend at the free, held in the retaining strip 30 ends in installation ports 24 and 25, which lie in a vertical installation level. Depending on the orientation, the connection is moved to the left (Fig. 1) or to the right (Fig. 2).

Andere Geräte-Anschlüsse 15 und 16 können ein im Wesentlichen horizontales Geräte-Anschlusspaar bilden, wobei die Geräte-Anschlüsse 15 und 16 in den zugekehrten, vertikalen Randbereichen der Rückwand 12 zu den vertikalen Seitenwänden denselben Abstand aufweisen. Horizontal sind die Geräte-Anschlusspaare 15, 16 so weit versetzt, dass sich die Geräte-Anschlüsse 15 und 16, die Rohrstücke 22 und 23 sowie die Installationsanschlüsse 26 und 27 vertikal nicht überlappen. Damit wird der Anschluss der Rohrstücke 20 bis 23 und die Anbringung der Anschlussleitungen an den Installationsanschlüssen 24 bis 27 nicht beeinträchtigt.Other device ports 15 and 16 may form a substantially horizontal device port pair, with the device ports 15 and 16 in the facing, vertical edge regions of the back wall 12 to the vertical sidewalls have the same distance. Horizontally, the device connection pairs 15, 16 are offset so far that the device connections 15 and 16, the tube sections 22 and 23 and the installation connections 26 and 27 do not overlap vertically. Thus, the connection of the pipe sections 20 to 23 and the attachment of the connecting lines to the installation ports 24 to 27 is not affected.

Beim rechten Anschluss nach Fig. 1 hat das Rohrstück 22 eine kleine Länge, damit es von dem rechten Geräte-Anschluss 16 bis zur rechten Installationsebene reicht. Für den linken Geräte-Anschluss 15 muss ein langes Rohrstück 23 verwendet werden, damit es bis zur rechten Installationsebene reicht. Die Installationsanschlüsse 24 bis 27 der Rohrstücke 20 bis 23 liegen in der rechten vertikalen Installationsebene.In the right-hand connector of FIG. 1, the length of tube 22 has a small length to extend from the right-hand device connector 16 to the right-hand installation plane. For the left device port 15, a long length of pipe 23 must be used to reach the right installation level. The installation ports 24 to 27 of the pipe sections 20 to 23 are in the right vertical installation plane.

Werden die Rohrstücke 22 und 23 an den Geräte-Anschlüssen 15 und 16 vertauscht und jeweils in die Gegenrichtung gedreht, dann wird der linke Anschluss nach Fig. 2 erreicht, wenn auch die an den Geräte-Anschlüssen 13 und 14 angeschlossenen Rohrstücke 20 und 21 um 180° gedreht werden.If the pipe sections 22 and 23 interchanged at the device terminals 15 and 16 and each rotated in the opposite direction, then the left terminal of Fig. 2 is achieved, although the connected to the device terminals 13 and 14 pipe sections 20 and 21 to Be turned 180 °.

Die Halteleiste 30 kann auch noch zusätzliche Aufnahmen für Rohrstücke 45 mit Installationsanschluss 46 aufweisen. Diese Rohrstücke 45 können Anschlüsse oder Verbindungen zu anderen Geräten herstellen.The retaining strip 30 may also have additional receptacles for pipe sections 45 with installation port 46. These pieces of pipe 45 can make connections or connections to other devices.

Wird ein Schichtladespeicher in einem Speicher-Gerät 40 untergebracht, das als Standgerät nach Fig. 3 ausgebildet ist, dann kann ein Wärmeerzeuger 10 nach Fig. 1 oder 2 auf die Deckwand 41 des Speicher-Gerätes 40 aufgestellt und mit diesem verbunden werden, wie die Fig. 4 und 5 zeigen. Dabei kann der Wärmeerzeuger 10 in zwei vertikalen Trägerschienen 31 und 32 befestigt und so mit dem Speicher-Gerät 40 verbunden werden, dass die Vorderseiten bündig ineinander übergehen. Das Speicher-Gerät 40 nach Fig. 3 hat dieselbe Breite wie der Wärmeerzeuger 10, seine Bautiefe ist jedoch größer, so dass ein Teil der Deckwand 41 beim Gesamtgerät 50 hinter der Rückseite des Wärmeerzeugers 10 freiliegt. In diesem freiliegenden Bereich trägt das Speicher-Gerät 40 die zugehörigen Geräte-Anschlüsse 42 bis 44, die, wie die Rohrleitung 45 zeigt auch zur Halteleiste 30 geführt und dort als Installationsanschlüsse 46 enden können. Diese Geräte-Anschlüsse 42 und'43 können auch mit Rohrleitungen in den Wärmeerzeuger 10 hineingeführt und dort mit einem Wärmetauscher verbunden werden.If a stratified storage is housed in a storage device 40, which is formed as a standalone device according to FIG. 3, then a heat generator 10 of FIG. 1 or 2 can be placed on the top wall 41 of the storage device 40 and with connected to this, as Figs. 4 and 5 show. In this case, the heat generator 10 can be mounted in two vertical support rails 31 and 32 and connected to the storage device 40 so that the front sides are flush with each other. The storage device 40 of FIG. 3 has the same width as the heat generator 10, but its depth is greater, so that a part of the top wall 41 in the entire apparatus 50 is exposed behind the back of the heat generator 10. In this exposed area, the storage device 40 carries the associated device ports 42 to 44, which, like the pipeline 45, also leads to the retaining strip 30 and ends there as installation ports 46. These device connections 42 and 43 can also be led into the heat generator 10 with pipelines and connected there to a heat exchanger.
