Description

Die vorliegende Erfindung betrifft ein Modul zur Wassererwärmung mit einem Wärmetauscher, der einen Primärbereich und einen Sekundärbereich aufweist, und einer Pumpe, die von einer wärmegedämmten Abdeckung eines Gehäuses abgedeckt sind.The present invention relates to a module for heating water with a heat exchanger having a primary portion and a secondary portion, and a pump, which are covered by a thermally insulated cover of a housing.

Die EP 2 498 007 A1 und die EP 0 693 657 A1 offenbaren eine Wärmedämm-Vorrichtung für eine hydraulische Regelgruppe, wobei die Wärmedämmung die gesamte hydraulische Regelgruppe umschließt. Die DE 10 2008 033 773 A1 offenbart ein Gehäuse für ein Heizgerät und ein Heizgerät. Gemäß der Offenbarung der DE 20 2011 104 841 U1 ist eine hydraulische Regelgruppe von einem wärmedämmenden Gehäuse abgedeckt.The EP 2 498 007 A1 and the EP 0 693 657 A1 disclose a thermal insulation device for a hydraulic control group, wherein the thermal insulation encloses the entire hydraulic control group. The DE 10 2008 033 773 A1 discloses a housing for a heater and a heater. According to the disclosure of DE 20 2011 104 841 U1 a hydraulic control group is covered by a heat-insulating housing.

Die DE 199 12 284 A1 und die EP 2 093 517 B1 offenbaren jeweils Module zur Wassererwärmung mit einem Brenner und weiteren Installationen, durch welche das Modul zu einer Kompakt-Heizungsanlage wird, die geeignet ist, eine Wohneinheit zu beheizen.The DE 199 12 284 A1 and the EP 2 093 517 B1 each reveal modules for heating water with a burner and other installations, through which the module becomes a compact heating system, which is suitable to heat a residential unit.

Das Modul ist üblicherweise Teil einer Installation in einem Gebäude zur Nutzung von Primärenergie (beispielsweise Heizungswasser, Glykolgemisch, Solewasser oder dergleichen) durch Abgabe an ein sekundäres Medium, in der Regel Trink- oder Brauchwasser. Die Komponenten des Moduls sind entsprechend der Energieeinsparverordnung gedämmt. So sind der Wärmetauscher und die Pumpe üblicherweise von einer wärmegedämmten Abdeckung überdeckt, welche diese Komponenten wärmedämmend umschließt. Das erfindungsgemäße Modul hat üblicherweise keinen eigenständigen Brenner. Das Modul hat üblicherweise lediglich Zu- und Ableitungsrohre für den Sekundär- und den Primärkreislauf und einen Wärmetauscher, um Wärme zwischen dem Primär- und dem Sekundärkreislauf zu tauschen. Die Pumpe ist dem Primär- oder dem Sekundärkreislauf zugeordnet, und zwar bevorzugt dem Einlassbereich des Primärkreislaufs.The module is usually part of an installation in a building for the use of primary energy (for example, heating water, glycol mixture, brine or the like) by delivery to a secondary medium, usually drinking or service water. The components of the module are insulated in accordance with the Energy Saving Ordinance. Thus, the heat exchanger and the pump are usually covered by a thermally insulated cover which encloses these components heat-insulating. The module according to the invention usually has no independent burner. The module usually has only supply and discharge pipes for the secondary and primary circuits and a heat exchanger to exchange heat between the primary and secondary circuits. The pump is assigned to the primary or the secondary circuit, preferably the inlet region of the primary circuit.

Abhängig von dem Massestrom innerhalb des Moduls und der Temperatur des eingeleiteten Mediums, welches die Primärenergie in das Modul einbringt, können innerhalb der Abdeckung relativ hohe Temperaturen entstehen. Nicht selten überschreiten diese Temperaturen die üblicherweise für die Pumpe festgelegte Maximaltemperatur, die beispielsweise 55 °C betragen kann. Somit wird die Pumpe außerhalb ihrer Spezifikation betrieben und die Lebensdauer der Pumpe wird herabgesetzt bzw. die Gewährleistung des Herstellers der Pumpe erlischt.Depending on the mass flow within the module and the temperature of the introduced medium, which introduces the primary energy into the module, relatively high temperatures can arise within the cover. Not infrequently, these temperatures exceed the maximum temperature usually set for the pump, which may be 55 ° C, for example. Thus, the pump is operated outside its specification and the life of the pump is reduced or the warranty of the manufacturer of the pump goes out.

Die vorliegende Erfindung will insofern Abhilfe schaffen und ein verbessertes Modul zur Wassererwärmung angeben.The present invention seeks to remedy this and specify an improved module for heating water.

Gemäß der vorliegenden Erfindung wird hierzu ein Modul mit den Merkmalen von Anspruch 1 vorgeschlagen. Dieses zeichnet sich durch eine Pumpeneinhausung aus, die in dem Gehäuse vorgesehen ist. Die Pumpeneinhausung haust die Pumpe zumindest teilweise gegenüber dem Wärmetauscher wärmedämmend ein.According to the present invention, a module with the features of claim 1 is proposed for this purpose. This is characterized by a Pumpeneinhausung, which is provided in the housing. The pump housing houses the pump at least partially thermally insulated from the heat exchanger.

Dabei besteht die Pumpe regelmäßig aus einem Motor, einer Elektronik und einem wasserführenden Bereich. Die Elektronik ist regelmäßig herstellerseits mit dem Motor fest verbunden. Soweit mit der vorliegenden Erfindung vorgeschlagen wird, die Pumpe zumindest teilweise gegenüber dem Wärmetauscher wärmedämmend einzuhausen, ist damit gefordert, dass zumindest die Elektronik innerhalb der Pumpeneinhausung vorgesehen ist. Üblicherweise durchragt der Motor die Pumpeneinhausung, so dass der wasserführende Bereich der Pumpe außerhalb der Einhausung vorgesehen ist, der üblicherweise mit dem warmen Medium durchströmt wird. So ergibt sich durch die thermische Isolation der Pumpeneinhausung auch eine thermische Entkopplung zwischen verschiedenen Pumpenteilen, wobei der wasserführende Bereich außerhalb der Pumpeneinhausung und zumindest die Elektronik innerhalb der Einhausung vorgesehen ist. Der Motor durchragt üblicherweise die Pumpeneinhausung.The pump regularly consists of a motor, electronics and a water-bearing area. The electronics are regularly connected to the motor by the manufacturer. As far as proposed by the present invention, einzhrhausen the pump at least partially relative to the heat exchanger, it is required that at least the electronics is provided within the Pumpeneinhausung. Usually, the engine extends through the pump housing, so that the water-bearing portion of the pump is provided outside the housing, which is usually flowed through with the warm medium. Thus, thermal insulation of the pump housing also results in thermal decoupling between different pump parts, with the water-conducting area outside the pump housing and at least the electronics inside the enclosure being provided. The engine usually passes through the pump housing.

Die Pumpeneinhausung nach der vorliegenden Erfindung ist üblicherweise durch ein wärmedämmendes Gehäuse gebildet, welches die Pumpe zumindest teilweise umgibt, indes unabhängig von der wärmegedämmten Abdeckung des Moduls ausgebildet ist und auch bevorzugt keine weiteren Elemente des Moduls, außer die Pumpe bzw. Teile der Pumpe, wärmedämmend umschließt.The pump housing according to the present invention is usually formed by a heat-insulating housing which at least partially surrounds the pump, however, is formed independently of the thermally insulated cover of the module and also preferably no further elements of the module, except the pump or parts of the pump, heat-insulating encloses.

Die erfindungsgemäße Pumpeneinhausung hat ferner Ein- und Auslassöffnungen, die mit der Umgebung kommunizieren. So ist über diese Öffnungen die Möglichkeit geschaffen, das/die Teil/e der Pumpe durch ein Fluid zu kühlen, das/die innerhalb der Pumpeneinhausung vorgesehen ist/sind.The pump housing according to the invention also has inlet and outlet ports which communicate with the environment. Thus, via these openings, it is possible to cool the part (s) of the pump by a fluid provided inside the pump housing.

Die konvektive Kühlung des in der Pumpeneinhausung vorgesehenen Pumpenteils erfolgt dabei vorzugsweise über natürliche Konvektion. Hierzu wird die Pumpeneinhausung so ausgestaltet, dass die mit der Erwärmung der eintretenden Luft einhergehende Dichteverringerung genutzt wird, eine Strömung zu erzeugen. So befindet sich die Auslassöffnung üblicherweise in der Vertikalen über dem in der Pumpeneinhausung vorgesehenen Pumpenteil.The convective cooling of the pump housing provided in the pump part is preferably carried out by natural convection. For this purpose, the Pumpeneinhausung is designed so that the associated with the heating of the incoming air density reduction is used to generate a flow. So is the outlet opening usually in the vertical above the pump housing provided in the pump housing.

Damit ist die Möglichkeit geschaffen, den wärmeempfindlichen Teil der Pumpe thermisch von dem Inneren des Moduls, insbesondere dem Wärmetauscher und den hierzu führenden Rohren zu entkoppeln. Durch die konvektive Überströmung des Pumpenteiles innerhalb der Pumpeneinhausung wird verhindert, dass sich Wärme staut. So kann die Pumpe zuverlässig unterhalb der herstellerseits angegebenen Maximaltemperatur für den Betrieb und dementsprechend innerhalb der Spezifikation betrieben werden. Bei geschlossenem Gehäuse liegen an diesem außen üblicherweise die Ein- und Auslassrohre der Verrohrung für den Primär- und Sekundärbereich frei. Alle anderen wasserführenden Teile des Moduls sind innerhalb des Gehäuses vorgesehen.This creates the possibility of thermally decoupling the heat-sensitive part of the pump from the interior of the module, in particular the heat exchanger and the tubes leading thereto. The convective overflow of the pump part inside the pump housing prevents heat from accumulating. Thus, the pump can be reliably operated below the factory specified maximum temperature for operation and accordingly within the specification. When the housing is closed, the inlet and outlet pipes of the piping for the primary and secondary areas are usually exposed on this exterior. All other water-carrying parts of the module are provided inside the housing.

Das Ausführungsbeispiel hat eine Basisplatte 2 zur Wandmontage des gezeigten Moduls, auf welcher die wesentlichen Komponenten des Moduls montiert sind. Die Basisplatte 2 kann mit einer zweiteiligen Abdeckung 4 bestehend aus einem Gehäuseoberteil 6 und einem Gehäuseunterteil 8 überdeckt werden. Die Basisplatte 2 sowie die Abdeckung 4 bestehen aus einem wärmedämmenden Material, beispielsweise einem geschäumten Kunststoff. Bei dem gezeigten Ausführungsbeispiel bestehen diese Teile aus expandiertem Polypropylen (EPP).The embodiment has a base plate 2 for wall mounting of the module shown, on which the essential components of the module are mounted. The base plate 2 can be covered with a two-part cover 4 consisting of an upper housing part 6 and a lower housing part 8. The base plate 2 and the cover 4 are made of a thermally insulating material, such as a foamed plastic. In the embodiment shown, these parts are made of expanded polypropylene (EPP).

Wie Fig. 1 ferner erkennen lässt, haben Gehäuseoberteil 6 und Gehäuseunterteil 8 an ihren aneinanderliegenden Seitenflächen Formschlusselemente, die ein Übergreifen der Ränder der Teile 6, 8 erlauben, um diese möglichst dicht miteinander zu verbinden. Hierdurch soll eine gute Dämmung des durch die Basisplatte 2 und die beiden Gehäuseteile 6, 8 gebildeten Gehäuses bewirkt werden.The base plate 2 has at its longitudinal side edges projecting guide rails 10, which are integrally formed from the material of the EPP on the base plate 2 and together with guide grooves 12 of the cover 4 form a sliding guide, so that the lower housing part 8 from below and the upper housing part 6 from above the base plate 2 can be pushed and held it. As Fig. 1 can also be seen, housing upper part 6 and lower housing part 8 have on their adjacent side surfaces form-fitting elements which allow the edges of the parts 6, 8 to overlap, to connect them as closely as possible. This is intended to effect a good insulation of the housing formed by the base plate 2 and the two housing parts 6, 8.

Wie Fig. 3 erkennen lässt, ist zwischen dem Plattenwärmetauscher 14 und dem motorbetriebenen Absperrventil 36 eine Wärmeabschirmplatte 48 vorgesehen. Der Plattenwärmetauscher 14 ist über die Überwurfmuttern mit den zugeordneten Rohrstücken 20, 22, 30, 32 verschraubt und dementsprechend fluidmäßig mit dem Primärkreislauf PK und dem Sekundärkreislauf SK verbunden. Der Plattenwärmetauscher 14 ist relativ zu der durch die Längsseiten der Basisplatte 2 vorgegebene vertikale Erstreckung schräg eingebaut, und zwar vorliegend mit einem Neigungswinkel von etwa 30° relativ zu der Vertikalen. Von der Basisplate 2 ragen im Bereich der oberen und unteren Endseiten leicht nach innen versetzt vorgesehene Stege 50 ab, die einteilig an der Basisplatte 2 aus dem Material der Basisplatte 2 ausgeformt sind und der Befestigung von Gehäuseoberteil und Gehäuseunterteil 6, 8 wie auch der besseren Wärmedämmung unmittelbar benachbart zu den Rohrstücken 18, 20, 22, 24 dienen.As Fig. 3 can be seen, a Wärmeabschirmplatte 48 is provided between the plate heat exchanger 14 and the motor-operated shut-off valve 36. The plate heat exchanger 14 is screwed via the union nuts with the associated pipe sections 20, 22, 30, 32 and accordingly fluidly connected to the primary circuit PK and the secondary circuit SK. The plate heat exchanger 14 is mounted obliquely relative to the predetermined by the longitudinal sides of the base plate 2 vertical extent, in the present case with an inclination angle of about 30 ° relative to the vertical. From the base plate 2 protrude in the region of the upper and lower end sides slightly offset inwardly provided webs 50, which are integrally formed on the base plate 2 of the material of the base plate 2 and the attachment of the upper housing part and lower housing part 6, 8 as well as the better thermal insulation immediately adjacent to the pipe sections 18, 20, 22, 24 serve.

Mit Bezugszeichen 52 ist eine Pumpeneinhausung gekennzeichnet, die durch ein Kunststoffformteil gebildet ist. Dieses Kunststoffformteil hat stirnseitig vorspringende Verriegelungszapfen 54, welche in korrespondierend hierzu an der Basisplatte 2 ausgeformte Verriegelungsausnehmungen 56 eingreifen, um die Pumpeneinhausung 52 mit der Basisplatte 2 durch Aufstecken formschlüssig zu verbinden. Die Pumpeneinhausung 52 umgibt einen Motor 58 mit einer daran vorgesehenen, nicht im Detail gezeichneten Pumpensteuerung. Ein Boden 60 des Pumpengehäuses 52 (vgl. Fig. 3) wird von einem Endbereich des Motors 58 und teilweise von dem Propellergehäuse 26 durchragt. Eine in dem Boden 60 hierzu ausgebildete Durchlassöffnung 62 ist so dimensioniert, dass diese Teile der Pumpe 28 in den Boden 60 eingepasst sind. Die Verbindung zwischen dem Boden 60 und der Pumpe 28 ist hier idealerweise zumindest annähernd fluiddicht. Auf der dem Boden 60 gegenüberliegenden Seite bildet die Pumpeneinhausung 52 eine Einlassöffnung 64 aus. Diese Einlassöffnung 64 wird allein durch die umfänglichen Wandungen 66 der Pumpeneinhausung 52 vorgegeben. So liegt der Motor 58 der Pumpe 28 in der Einlassöffnung 64 frei und hat einen allseitigen Abstand zu den Innenflächen der umfänglichen Wandungen 66, die zusammen mit einer Bodensenke 68, die an der Basisplatte 2 ausgeformt ist, eine zylindrische Umfangsfläche definieren, die den Motor 58 mit Abstand umgibt. Die obere umfängliche Wandung 66 der Pumpeneinhausung 52 ist von einem Kaminsegment 70 überragt, welches einteilig an der Pumpeneinhausung 52 vorgesehen ist und eine Auslassöffnung 72 vorgibt, die in einer Kaminausnehmung 74 des Gehäuseoberteils 6 dichtend aufgenommen ist. Von der Basisplatte 2 abragende und durch diese ausgebildete Positionierstege 76, die parallel und mit Abstand zu der Oberkante der Basisplatte 2 vorgesehen sind, passen das Kaminsegment 70 zwischen sich ein.Reference numeral 52 denotes a pump housing, which is formed by a plastic molding. This plastic molding has frontally projecting locking pin 54 which engage in corresponding thereto on the base plate 2 formed locking recesses 56 to connect the Pumpeneinhausung 52 with the base plate 2 by plugging form-fitting manner. The pump housing 52 surrounds a motor 58 with a pump control provided thereon, not drawn in detail. A bottom 60 of the pump housing 52 (see. Fig. 3 ) is penetrated by an end portion of the motor 58 and partially by the propeller housing 26. One in the ground A passage opening 62 designed for this purpose is dimensioned such that these parts of the pump 28 are fitted into the floor 60. The connection between the bottom 60 and the pump 28 is ideally at least approximately fluid-tight here. On the side opposite the bottom 60, the pump housing 52 forms an inlet opening 64. This inlet opening 64 is predetermined solely by the circumferential walls 66 of the pump housing 52. Thus, the motor 58 of the pump 28 is exposed in the inlet port 64 and is spaced from the inside surfaces of the peripheral walls 66 by all-round, which together with a bottom recess 68 formed on the base plate 2, define a cylindrical peripheral surface defining the motor 58 surrounds with distance. The upper circumferential wall 66 of the pump housing 52 is surmounted by a chimney segment 70, which is provided integrally on the pump housing 52 and defines an outlet opening 72, which is sealingly received in a chimney recess 74 of the housing upper part 6. From the base plate 2 projecting and formed by this positioning webs 76, which are provided in parallel and spaced from the upper edge of the base plate 2, fit the chimney segment 70 between them.

Die die Einlassöffnung 64 ausbildenden Stirnseiten der umfänglichen Wandungen 66 sind zur dichtenden Anlage an eine Seitenwand des Gehäuseoberteils 6 konturiert ausgebildet und schließen an einen seitlichen Lufteinlass 78 an, der an einer Seitenwandung des Gehäuseoberteils 6 ausgespart ist.The end faces of the circumferential walls 66 forming the inlet opening 64 are contoured for sealing engagement with a side wall of the housing upper part 6 and adjoin a lateral air inlet 78 which is recessed on a side wall of the housing upper part 6.

Nach Montage des Ausführungsbeispiels umschließt die Kaminausnehmung 74 das Kaminsegment 40 endseitig, wodurch ein oberseitiger Luftauslass für das Ausströmen von Luft aus der Pumpeneinhausung 52 durch die Abdeckung 4 gebildet ist. Die in Fig. 1 erkennbaren Längsschlitze benachbart zu der Kaminausnehmung 74 umschließen im Wesentlichen dichtend die Rohrstücke 18, 20 des Primärbereiches PK. Eine entsprechende Ausgestaltung ist an der Unterseite des Gehäuseunterteils 8 vorgesehen, um Durchlässe für die Rohrstücke 22, 24 des Sekundärbereiches SK zu schaffen.After mounting the embodiment, the Kaminausnehmung 74 surrounds the chimney segment 40 end, whereby an upper-side air outlet for the outflow of air from the pump housing 52 is formed by the cover 4. In the Fig. 1 Identifiable longitudinal slots adjacent to the fireplace recess 74 enclose the pipe sections 18, 20 of the primary area PK in a substantially sealing manner. A corresponding embodiment is provided on the underside of the housing lower part 8 to provide passages for the pipe sections 22, 24 of the secondary region SK.

Beim Betrieb führt eine Erwärmung der Pumpe 28 gegenüber der Umgebungsluft zwangsläufig dazu, dass die so im Bereich des Motors 58 entstehende Warmluft durch den Kamin des Kaminsegmentes 70 nach oben ausgefördert wird. Der sich hierdurch ergebende Kamineffekt führt zu einer konstanten Durchströmung der Pumpeneinhausung 52 durch den seitlichen Lufteinlass 78, die Einlassöffnung 64, durch den Kamin des Kaminsegmentes 70 zu der Auslassöffnung 72. Dieser Luftstrom umströmt die Pumpe 28 umfänglich. Der Kamin verstärkt die konvektive Kühlung innerhalb der Pumpeneinhausung 52 und verhindert dementsprechend überkritische Temperaturen im Bereich der Pumpe 28 innerhalb der Pumpeneinhausung 52. So ist durch das gezeigte Ausführungsbeispiel eine effektive Kühlung der Pumpe 28 möglich. Die wärmeführenden Teile der Pumpe 28 befinden sich außerhalb der Pumpeneinhausung 52, so dass die thermisch sensiblen Teile der Pumpe 28 zusätzlich vor übermäßiger Übererwärmung durch die warmen Teile der Pumpe 28 selbst geschützt sind.During operation, heating of the pump 28 with respect to the ambient air inevitably causes the warm air thus produced in the region of the motor 58 to be conveyed upwards through the chimney of the chimney segment 70. The resulting chimney effect leads to a constant flow through the pump housing 52 through the side air inlet 78, the inlet opening 64, through the chimney of the chimney segment 70 to the outlet opening 72. This air flow flows around the pump 28 circumferentially. The chimney enhances the convective cooling within the pump housing 52 and accordingly prevents supercritical temperatures in the area of the pump 28 within the pump housing 52. Thus, by the embodiment shown, an effective cooling of the pump 28 is possible. The heat-conducting parts of the pump 28 are located outside the pump housing 52, so that the thermally sensitive parts of the pump 28 are additionally protected against excessive overheating by the warm parts of the pump 28 itself.
