Description

Die Erfindung betrifft eine Außeneinheit für eine Luft-Wasser-Wärmepumpe. Zur Nutzung der Wärme der Umgebungsluft verwenden Luft-Wasser-Wärmepumpen eine außerhalb des zu beheizenden Gebäudes stehende Außeneinheit, die zumindest einen Wärmetauscher und einen Lüfter beinhaltet. Eine solche Luft-Wasser-Wärmepumpe ist aus der Patentanmeldung DE 10 2011 012 109 A1 bekannt. Die DE 10 2014 008 379 A1 offenbart eine Außeneinheit für eine Luft-Wasser-Wärmepumpe mit den Merkmalen des Oberbegriffs von Anspruch 1. Die DE 10 2011 102 026 A1 zeigt ein Tragwerk für einen Lüfter aus expandiertem Polypropylen. Die US 5 085 057 A zeigt ein integriertes Klimagerät mit einer Trennwand aus expandiertem Polypropylen.The invention relates to an outdoor unit for an air-water heat pump. To use the heat of the ambient air use air-water heat pumps outside of the building to be heated outdoor unit that includes at least a heat exchanger and a fan. Such an air-water heat pump is from the patent application DE 10 2011 012 109 A1 known. The DE 10 2014 008 379 A1 discloses an outdoor unit for an air-to-water heat pump having the features of the preamble of claim 1. The DE 10 2011 102 026 A1 shows a support structure for a fan made of expanded polypropylene. The US 5 085 057 A shows an integrated air conditioner with a divider made of expanded polypropylene.

Grundsätzlich besteht bei solchen gattungsgemäßen Außeneinheiten das Problem der Geräuschbelästigung aufgrund des rotierenden Lüfters und sofern vorhanden des integrierten Kompressors, insbesondere nachts in Wohngebieten.Basically, in such generic outdoor units, the problem of noise pollution due to the rotating fan and, if available, the integrated compressor, especially at night in residential areas.

Aufgabe der vorliegenden Erfindung ist es, einen Beitrag zur weiteren Senkung der akustischen Emissionen zu leisten. Eine weitere Aufgabe ist es, die Herstellkosten zu senken sowie eine einfachere Bereitstellung von Ersatzteilen zu ermöglichen. Diese Aufgabe wird gemäß dem unabhängigen Anspruch dadurch gelöst, dass das Lüftergitter akustisch von dem Gehäuse entkoppelt wird. Dies erfolgt erfindungsgemäß dadurch, dass das Lüftergitter von einem Tragwerk aus geschäumtem Kunststoff, bevorzugt aus expandiertem Polypropylen (EPP), gehalten wird. Über dieses Tragwerk ist das Lüftergitter indirekt mit der Bodenplatte bzw. mit dem Gehäuse verbunden. Dadurch werden Schwingungen und Körperschall, die durch Luftverwirbelungen am Lüftergitter durch die einströmende Luft oder aufgrund von starkem Wind erzeugt werden, nicht an das Gehäuse weitergeleitet.The object of the present invention is to make a contribution to further reducing the acoustic emissions. Another object is to reduce the manufacturing costs and to allow easier provision of spare parts. This object is achieved according to the independent claim in that the fan grille is acoustically decoupled from the housing. This is done according to the invention in that the fan grid is held by a framework of foamed plastic, preferably expanded polypropylene (EPP). About this structure, the fan grid is indirectly connected to the bottom plate or to the housing. As a result, vibrations and structure-borne noise, which are generated by air turbulence on the fan grille by the incoming air or due to strong wind, not forwarded to the housing.

In einer Weiterbildung der Erfindung wird das Lüftungsgitter durch Aufnahmemittel im Tragwerk aufgenommen, die aus vertikalen Nuten und Auflagen gebildet werden. Somit kann das Lüftergitter von oben in die vertikalen Nuten eingeschoben werden, bis es auf den Auflagen auffliegt, welche das Gewicht des Lüftergitter tragen.In a further development of the invention, the ventilation grille is received by receiving means in the supporting structure, which are formed from vertical grooves and supports. Thus, the fan grille can be inserted from above into the vertical grooves until it flies on the supports that carry the weight of the fan grille.

In einer besonders bevorzugten Ausführungsvariante der Erfindung besteht das Lüftergitter aus mehreren vertikal übereinander angeordneten Lüftergitter-Elementen. Dadurch wird einerseits erreicht, dass die Lüftergitter-Elemente für mehrere Baugrößen einer Außeneinheit verwendet werden können. So kann beispielsweise für eine kleine Baugröße eine Außeneinheit mit einem Lüftergitter bestehend aus drei Lüftergitter-Elementen vorgesehen werden, während größere Baugrößen Lüftergitter mit einer höheren Anzahl von Lüftergitter-Elementen aufweisen. Dadurch können die selben Lüftergitter-Elemente für unterschiedliche Baugrößen verwendet werden, was die Variantenvielzahl der Einzelteile für die Baureihe reduziert und die Ersatzteil-Bevorratung vereinfacht. Andererseits kann bei einer Beschädigung des Lüftergitters, beispielsweise durch einen Fußball, dieses leicht und kostengünstig durch Austausch eines einzelnen Lüftergitter-Elements repariert werden.In a particularly preferred embodiment of the invention, the fan grille consists of a plurality of vertically superposed fan grille elements. This ensures, on the one hand, that the fan grille elements can be used for several sizes of an outdoor unit. For example, for a small size, an outdoor unit with a fan grille consisting of three fan grille elements can be provided, while larger sizes have fan grids with a higher number of fan grille elements. As a result, the same fan grill elements can be used for different sizes, which reduces the number of variants of the individual parts for the series and simplifies the spare parts stocking. On the other hand, in case of damage to the fan grille, for example by a football, this can be easily and inexpensively repaired by replacing a single fan grille element.

The invention will now be explained in detail with reference to FIGS. They show:
FIG. 1:
the outdoor unit with housing,
FIG. 2:
the outdoor unit with partially opened housing,
FIG. 3:
the structure.

Figur 1 stellt die Außeneinheit mit Gehäuse dar. Eine gattungsgemäße Außeneinheit zur Nutzung der Umgebungsluft für Luft-Wasser-Wärmepumpen ist außerhalb des zu beheizenden Gebäudes aufgestellt. Sie enthält zumindest einen Wärmetauscher zum Übertragen der Wärme von der Außenluft auf ein Wärmeträgermedium, das über eine Rohrverbindung in das Gehäuse geleitet wird. Optional kann innerhalb der Außeneinheit auch der Kompressor vorgesehen sein, anderenfalls ist er innerhalb des Gebäudes vorgesehen. Die Außeneinheit ist von einem Gehäuse 3 umgeben und ruht auf einem Unterbau 1. Um die Wärme der Außenluft dem Wärmetauscher zuzuführen, ist bei gattungsgemäßen Außeneinheit ein Gebläse vorgesehen, das die Außenluft durch ein Lüftergitter 2 dem Wärmetauscher zuführt. Füße 11 ermöglichen die Aufstellung und die Befestigung der Außeneinheit. FIG. 1 represents the outdoor unit with housing. A generic outdoor unit for using the ambient air for air-water heat pumps is placed outside the building to be heated. It contains at least one heat exchanger for transferring the heat from the outside air to a heat transfer medium, which is passed via a pipe connection in the housing. Optionally, the compressor can also be provided inside the outdoor unit, otherwise it is provided inside the building. The outdoor unit is surrounded by a housing 3 and rests on a substructure 1. In order to supply the heat of the outside air to the heat exchanger, a blower is provided in the generic outdoor unit, which supplies the outside air through a fan grille 2 to the heat exchanger. Feet 11 allows the installation and attachment of the outdoor unit.

Figur 2 zeigt die Außeneinheit mit teilweise geöffnetem Gehäuse 3. Aus Gründen der Übersichtlichkeit sind der Wärmetauscher, Lüfter sowie weitere Bestandteile der Hydraulik und des optionalen Kältekreises mit Kompressor nicht dargestellt. Der Unterbau 1 in Form einer Bodenplatte trägt und fixiert die einzelnen dargestellten und nicht dargestellten Bestandteile der Außeneinheit. Am Rand des Unterbaus ist mittels Schrauben ein senkrecht stehendes Tragwerk aus geschäumtem Kunststoff mit dem Unterbau 1 verbunden. Dieses Tragwerk 4 ist im Detail in Figur 3 dargestellt. FIG. 2 shows the outdoor unit with partially open housing 3. For reasons of clarity, the heat exchanger, fan and other components of the hydraulic system and the optional refrigerant circuit with compressor are not shown. The substructure 1 in the form of a base plate supports and fixes the individual components of the outdoor unit, which are not shown. At the edge of the substructure is by means of screws a vertical support structure made of foamed plastic connected to the substructure 1. This structure 4 is in detail in FIG. 3 shown.

Der nicht dargestellte Lüfter rotiert im Betrieb innerhalb einer Öffnung 44 des Tragwerks 4 und fördert Luft durch das Lüftergitter 2 zu einem hier nicht dargestellten Wärmetauscher auf der Innenseite des Tragwerks 4. Die Befestigung des Lüfters am Tragwerk 4 ist im Detail in der Patentanmeldung DE 102016217474.6 beschrieben. Erfindungsgemäß ist das Tragwerk 4 aus geschäumtem Kunststoff, bevorzugt aus EPP. Der Vorteil dieses Materials ist eine gute Schwingungsdämpfung, so dass entstehende Schwingungen nicht auf den Unterbau 1 oder das Gehäuse 3 übertragen werden. Das Tragwerk kann aus mehreren Tragwerk-Elementen bestehen, wie in der Patentanmeldung DE 102016217474.6 beschrieben. Diese sind mittels Noppen 43 zusammengesteckt und mit Klammern untereinander verbunden.The fan, not shown, rotates during operation within an opening 44 of the structure 4 and promotes air through the fan grille 2 to a heat exchanger, not shown here on the inside of the structure 4. The attachment of the fan to the structure 4 is in detail in the patent application DE 102016217474.6 described. According to the invention, the supporting structure 4 is made of foamed plastic, preferably of EPP. The advantage of this material is a good vibration damping, so that resulting vibrations are not transmitted to the substructure 1 or the housing 3. The structure may consist of several structural elements, as in the patent application DE 102016217474.6 described. These are plugged together by nubs 43 and connected to each other with brackets.

An der Außenseite weist das Tragwerk 4 seitlich der Öffnung 44 vertikale Nuten 41 auf. In diese Nuten 41 sind mehrere Lüftergitter-Elementen 21 einschiebbar. Dazu weisen die Lüftergitter-Elemente 21 seitlich korrespondierende Vorsprünge auf oder die Nuten 41 sind so groß, dass das Lüftergitter 21 formschlüssig in die Nuten 41 eingreift. Im Betrieb liegt das unterste Lüftergitter-Element 21 auf Auflagen 42 des Tragwerks 4 auf, die aus dem geschäumten Kunststoff gebildet werden. Im einfachsten Fall wird das Lüftergitter 2 durch nur ein einziges großes Lüftergitter-Element 21 gebildet. Vorteilhaft ist es jedoch, dass Lüftergitter 2 aus mehreren kleinen Lüftergitter-Elementen 21 zu bilden. Diese werden bei der Montage nacheinander von oben in die Nuten 41 eingeführt. Damit die einzelnen Lüftergitter-Elemente 21 untereinander schwingungsarm aufeinander ruhen, sind an der Oberseite der Lüftergitter-Elemente 21 am Rand zwei oder über die Breite des Lüftergitter-Elements 21 verteilt mehrere Lüftergitter-Auflagen 22 vorgesehen, die optional aus einem schwingungdämpfenden Material sind. Die insgesamt schwingungdämpfende Aufnahme des Lüftergitters 2 bzw. der Lüftergitter-Elemente 21 trägt zur Geräuschminderung beim Betrieb der Außeneinheit bei. Die einzelnen Lüftergitter-Elemente 21 können für verschiedene Baugrößen eingesetzt werden und erleichtern den kostengünstigen Austausch im Reparaturfall.On the outside, the supporting structure 4 has lateral grooves 41 on the side of the opening 44. In these grooves 41 a plurality of fan grid elements 21 are inserted. For this purpose, the fan grid elements 21 laterally corresponding projections or the grooves 41 are so large that the fan grid 21 engages positively in the grooves 41. In operation, the lowest fan grid element 21 rests on supports 42 of the structure 4, which are formed from the foamed plastic. In the simplest case, the fan grille 2 is formed by only a single large fan grille element 21. It is advantageous, however, that fan grille 2 from several small fan grid elements 21 to form. These are introduced successively from above into the grooves 41 during assembly. So that the individual Fan grid elements 21 resting against each other with low vibration, a plurality of fan grid pads 22 are provided on the top of the fan grid elements 21 at the edge of two or over the width of the fan grid element 21, which are optionally made of a vibration-damping material. The overall vibration-damping reception of the fan grille 2 or the fan grille elements 21 contributes to the noise reduction during operation of the outdoor unit. The individual fan grid elements 21 can be used for different sizes and facilitate cost-effective replacement in case of repair.
