Description

Die Erfindung betrifft die Konstruktion eines Wärmepumpengehäuses einer außenstehenden Luft-Wasser-Wärmepumpe. Bei einer derartigen Wärmepumpe sind der Wärmepumpenkreislauf mit dem Arbeitsfluid wie auch der Lüfter im Außenbereich aufgestellt und nur die Anschlüsse für den Heizkreislauf für die Hausheizung und gegebenenfalls den Kältekreislauf für die Klimatisierung werden in das Gebäude hineingeführt.The invention relates to the construction of a heat pump housing for an external air-water heat pump. In such a heat pump, the heat pump circuit with the working fluid as well as the fan are set up outside and only the connections for the heating circuit for the house heating and possibly the cooling circuit for the air conditioning are led into the building.

Solche außenstehenden Luft-Wasser-Wärmepumpen können dabei in einigem Abstand zum Haus, oder auf dem Hausdach aufgestellt oder an der Außenwand montiert sein. In der Regel weisen sie einen Lüfter auf, der die Wärmetauscherflächen anströmt. Nicht immer sind die Gehäuse, in denen sich die Wärmepumpen befinden, leicht zugänglich.Such external air-water heat pumps can be set up at some distance from the house, on the house roof or mounted on the outside wall. As a rule, they have a fan that flows against the heat exchanger surfaces. The housings in which the heat pumps are located are not always easily accessible.

In der Vergangenheit sind solche Geräte meist mit Sicherheitskältemitteln betrieben worden, die im Falle einer Leckage ihr Kältemittel verloren haben, welches aber ansonsten kein Gesundheits- oder Sicherheitsproblem darstellte, sondern nach Reparatur der Leckage lediglich nachgefüllt werden musste. In neuerer Zeit wurde aber festgestellt, dass diese Sicherheitskältemittel die Ozonschicht zerstören und ihre Verwendung wurde stark eingeschränkt oder sogar ganz verboten. Die verwendeten Ersatz-Arbeitsfluide weisen solche günstigen Sicherheitseigenschaften leider nicht mehr auf.In the past, such devices were mostly operated with safety refrigerants that lost their refrigerant in the event of a leak, but which otherwise did not pose a health or safety problem, but only had to be topped up after the leak was repaired. More recently, however, it has been found that these safety refrigerants destroy the ozone layer and their use has been severely restricted or even banned entirely. The replacement working fluids used unfortunately no longer have such favorable safety properties.

Einige diese Ersatz-Arbeitsfluide sind brennbar, explosiv, gelegentlich auch leicht giftig. Aus diesem Grund sind Leckagedichtheit und Leckagedetektion weiterentwickelt worden. Außerdem ist der Wunsch entstanden, solche Wärmepumpen nicht mehr innerhalb der Wohngebäude, sondern außerhalb aufzustellen, um im Falle eines auftretenden Sicherheitsproblems innerhalb des Gebäudes in Sicherheit zu sein. Damit wurde das grundsätzliche Sicherheitsproblem in den Außenbereich verlagert, in dem die äußeren Bedingungen weniger kontrollierbar sind und die Anfälligkeit somit tendenziell steigt.Some of these substitute working fluids are flammable, explosive, and occasionally slightly toxic. For this reason, leak tightness and leak detection have been further developed. In addition, the desire arose to no longer set up such heat pumps inside the residential building, but outside, in order to be safe in the event of a security problem inside the building. This has shifted the fundamental security problem to the outside area, where the external conditions are less controllable and susceptibility tends to increase.

In sehr seltenen Fällen können Umgebungsbedingungen auftreten, die Schäden im Inneren des Aufstellungsgehäuses hervorrufen. Falls sich hierbei eine größere Leckage im Arbeitsfluid-Kreislauf einstellt, bei der aufgrund des Arbeitsdrucks schnell ein explosives Luft-Arbeitsmittel-Gemisch entsteht, sind Explosionen und Verpuffungen mit geringer Stärke möglich, die spezielle Sicherheitsmaßnahmen erfordern.In very rare cases, environmental conditions can occur that cause damage to the interior of the installation housing. If there is a major leakage in the working fluid circuit, in which an explosive mixture of air and working medium quickly develops due to the working pressure, explosions and deflagrations with low strength are possible, which require special safety measures.

Entsprechende Vorrichtungen sind aus dem Stand der Technik bereits bekannt geworden. So zeigen die US 2005/204767 A1 und die WO 2018/164434 A1 jeweils Vorrichtungen, bei denen

  • das Außengehäuse durch einen quaderförmigen steifen Rahmen, ein Fundament, Seitenteile, eine obere Abdeckung, eine Vorderseite und eine Rückseite gebildet wird,
  • der Rahmen auf dem Fundament befestigt ist und die Seitenteile und die obere Abdeckung am Rahmen befestigt ist,
  • an der Vorderseite und Rückseite des Außengehäuses Öffnungen sind, und diese Öffnungen durch Schutzgitter oder Wärmetauscher luftdurchlässig, für Gegenstände oder Tiere aber undurchlässig sind,
  • die übrige Vorderseite und Rückseite sowie die obere Abdeckung, die das Fundament und die Seitenteile undurchlässig ausgeführt sind,
  • die obere Abdeckung sowie die Seitenteile oben kraftschlüssig am Rahmen befestigt sind,
  • die kraftschlüssigen Verbindungen Schraubverbindungen sind,
  • die Seitenteile formschlüssig an den Seiten mit dem Rahmen verbunden sind,
  • die formschlüssigen Verbindungen (8) Einhakverbindungen sind,
  • und die Seitenteile bodenseitig im Rahmen eingefasst sind,
Corresponding devices are already known from the prior art. So they show US 2005/204767 A1 and the WO 2018/164434 A1 respectively devices in which
  • the outer housing is formed by a cuboid rigid frame, a foundation, side parts, a top cover, a front and a back,
  • the frame is attached to the foundation and the side panels and top cover are attached to the frame,
  • there are openings on the front and back of the outer housing, and these openings are air-permeable through protective grids or heat exchangers, but impermeable to objects or animals,
  • the rest of the front and back as well as the upper cover, which the foundation and the side parts are impermeable to,
  • the top cover and the side parts are firmly attached to the frame at the top,
  • the force-fit connections are screw connections,
  • the side parts are positively connected to the frame on the sides,
  • the form-fitting connections (8) are hook connections,
  • and the side parts are enclosed in the frame at the bottom,

Die Erfindung hat die Aufgabe, ein Gehäuse bereitzustellen, welches einerseits die Energie bei solchen Störungen in sicherer Weise absorbiert und ableitet, andererseits aber die Zugänglichkeit für Wartungsmaßnahmen erlaubt und welches am Aufstellungsort aus transportierbaren Einzelteilen montiert werden kann.The object of the invention is to provide a housing which, on the one hand, absorbs and dissipates the energy in a safe manner in the event of such malfunctions, but on the other hand allows accessibility for maintenance measures and which can be assembled at the installation site from transportable individual parts.

Diese Aufgabe wird gelöst durch ein Außengehäuse für eine Wärmepumpe, wobei das Außengehäuse eine Außeneinheit mit mindestens einem Wärmetauscher, der von Luft durchströmt wird, mindestens einem Lüfter, der Luft durch den Wärmetauscher zieht und aus einer Gehäuseöffnung ins Freie fördert, sowie eine Vielzahl von weiteren Gerätekomponenten enthalten kann, wobei

  • das Außengehäuse durch einen quaderförmigen steifen Rahmen, ein Fundament, Seitenteile, eine obere Abdeckung, eine Vorderseite und eine Rückseite gebildet wird,
  • der Rahmen auf dem Fundament befestigt ist und die Seitenteile und die obere Abdeckung am Rahmen befestigt ist,
  • an der Vorderseite und Rückseite des Außengehäuses Öffnungen sind, und diese Öffnungen durch Schutzgitter oder Wärmetauscher luftdurchlässig, für Gegenstände oder Tiere aber undurchlässig sind,
  • die übrige Vorderseite und Rückseite sowie die obere Abdeckung, die das Fundament und die Seitenteile undurchlässig ausgeführt sind,
  • die obere Abdeckung sowie die Seitenteile oben kraftschlüssig am Rahmen befestigt sind,
  • die kraftschlüssigen Verbindungen Schraubverbindungen sind,
  • die Seitenteile formschlüssig an den Seiten mit dem Rahmen verbunden sind,
  • die formschlüssigen Verbindungen (8) Einhakverbindungen sind,
  • die Seitenteile bodenseitig im Rahmen eingefasst sind,
  • und die bodenseitige Einfassung (9) so ausgeführt ist, dass sich durch Druck von innen das Seitentel (3) öffnet,
This object is achieved by an outer housing for a heat pump, the outer housing being an outdoor unit with at least one heat exchanger through which air flows, at least one fan that pulls air through the heat exchanger and conveys it out of a housing opening into the open, and a large number of others Device components may contain, where
  • the outer housing is formed by a cuboid rigid frame, a foundation, side parts, a top cover, a front and a back,
  • the frame is attached to the foundation and the side panels and top cover are attached to the frame,
  • there are openings on the front and back of the outer housing, and these openings are air-permeable through protective grids or heat exchangers, but impermeable to objects or animals,
  • the rest of the front and back as well as the upper cover, which the foundation and the side parts are impermeable to,
  • the top cover and the side parts are firmly attached to the frame at the top,
  • the force-fit connections are screw connections,
  • the side parts are positively connected to the frame on the sides,
  • the form-fitting connections (8) are hook connections,
  • the side parts are enclosed in the frame at the bottom,
  • and the bottom border (9) is designed so that the side part (3) opens when pressure is applied from the inside,

Hierdurch ergibt sich im Falle eines plötzlich auftretenden Überdrucks im Inneren des Außengehäuses, dass die Seitenteile an der bodenseitigen Einfassung am Rahmen öffnen und ein Druckausgleich stattfindet. Die Seitenteile selbst werden durch die oben angebrachten kraftschlüssigen Verbindungen sicher festgehalten und können sich nicht lösen. Auf diese Weise wird verhindert, dass Teile weggeschleudert werden können. Ein weiterer Abbau von Energie findet durch die formschlüssigen Verbindungen an den Seiten des Rahmens statt, die sich plastisch verformen und dadurch Energie absorbieren.In the event of a sudden overpressure in the interior of the outer housing, this results in the side parts opening on the frame on the bottom side and pressure equalization taking place. The side parts themselves are securely held in place by the non-positive connections at the top and cannot come loose. This prevents parts from being thrown away. A further reduction of energy takes place through the form-fitting connections on the sides of the frame, which deform plastically and thus absorb energy.

Weitere Ausgestaltungen der Erfindung betreffen die Verbindungen. Hierbei werden vorzugsweise für die kraftschlüssigen Verbindungen abschließbare Schraubverbindungen gewählt. Bodenseitig werden die Seitenteile nur eingefasst, so dass sie sich nach Art einer Sollbruchstelle bei auftretendem inneren Überdruck leicht lösen, von außen aber nicht einfach zu entfernen sind.Further embodiments of the invention relate to the connections. In this case, lockable screw connections are preferably chosen for the non-positive connections. On the bottom side, the side parts are only framed so that they can be easily detached like a predetermined breaking point when internal overpressure occurs, but cannot easily be removed from the outside.

Weitere Ausgestaltungen betreffen die Seitenteile selbst. Diese können aus Stahlblech mit Energie-absorbierenden Strukturen gewählt werden, wie sie auch im Automobilbau üblich sind.Further configurations relate to the side parts themselves. These can be selected from sheet steel with energy-absorbing structures, as are also common in automobile construction.

Die Erfindung wird anhand von Fig. 1 bis Fig. 4 näher erläutert. Es zeigen:

  • Fig. 1 eine schematische Darstellung einer Außenbox,
  • Fig. 2 eine schematische Darstellung der oberseitigen Befestigungen,
  • Fig. 3 eine schematische Darstellung der seitlichen Befestigungen,
  • Fig. 4 eine schematische Darstellung der unterseitigen Befestigungen.
The invention is based on FIGS. 1 to 4 explained in more detail. Show it:
  • Fig. 1 a schematic representation of an outer box,
  • Fig. 2 a schematic representation of the top mountings,
  • Fig. 3 a schematic representation of the lateral attachments,
  • Fig. 4 a schematic representation of the underside fastenings.

Fig. 1 zeigt eine schematische Darstellung einer Außenbox für eine Luft-Wasser-Wärmepumpe, wobei sich die Erfindung aber nicht auf solch einfache Wärmepumpensysteme beschränkt. Die Außenbox 1 weist einen Rahmen 2 auf, der aus 12 Streben besteht, 4 oben, 4 seitlich und 4 unten. Diese Streben können aus Winkelprofilen oder Hohlprofilen bestehen, die an ihren Ecken üblicherweise verschweißt sind, andere Befestigungsmöglichkeiten sind denkbar. Wichtig ist nur, dass diese Streben und ihre Verbindungen auch bei Überdruckfällen stabil sind und nicht nachgeben. Fig. 1 shows a schematic representation of an outer box for an air-water heat pump, but the invention is not limited to such simple heat pump systems. The outer box 1 has a frame 2, which consists of 12 struts, 4 at the top, 4 at the side and 4 at the bottom. These struts can consist of angle profiles or hollow profiles, which are usually welded at their corners, other fastening options are conceivable. It is only important that these struts and their connections are stable even in cases of excess pressure and do not give way.

An dem Rahmen 2 sind zwei Seitenteile 3, das Oberteil 4, die Front 5 und die Rückseite 6 befestigt. Der Rahmen selbst ist auf das Fundament (nicht gezeigt) montiert, wobei dieses Fundament auch aus einem Unterteil mit schwingungsgedämpften Füßen bestehen kann. Im Falle einer Überdrucksituation muss verhindert werden, dass sich Teile lösen und davonfliegen können. Während Front 5 und Rückseite 6 zwar luftdurchlässig sind, aber Einzelteile wie Wärmetauscher, Lüftungsgitter und Lüfter enthalten, müssen diese gut am Rahmen befestigt werden. Sie dürfen sich nicht lösen.Two side parts 3, the upper part 4, the front 5 and the rear 6 are attached to the frame 2. The frame itself is mounted on the foundation (not shown), whereby this foundation can also consist of a lower part with vibration-damped feet. In the event of an overpressure situation, it must be prevented that parts come loose and fly away. While the front 5 and back 6 are air-permeable, but contain individual parts such as heat exchangers, ventilation grids and fans, these must be firmly attached to the frame. You mustn't come off.

Auch das Oberteil 4 muss gut befestigt werden, dies geschieht mit kraftschlüssigen Verbindungen am Rahmen, in der Regel mit Schraubverbindungen, die mit Schlössern gegen unbefugten Eingriff gesichert werden können. Somit muss der entstandene Überdruck an den Seiten abgebaut werden.The upper part 4 must also be securely fastened, this is done with force-fit connections on the frame, usually with screw connections that can be secured against unauthorized access with locks. This means that the overpressure created on the sides must be relieved.

Fig. 2 zeigt hierzu eine schematische Darstellung der oberseitigen Befestigungen 7. Die Seitenteile 3 werden oben ebenfalls mit kraftschlüssigen Verbindungen am Rahmen 2, in der Regel mit Schraubverbindungen, die mit Schlössern gegen unbefugten Eingriff gesichert werden können, fixiert. Diese Fixierungen werden ebenso wie beim Oberteil 4 dahingehend ausgelegt, dass sie sich auch unter erheblicher Krafteinwirkung nicht lösen, sondern höchstens verformen. Fig. 2 shows a schematic representation of the top fastenings 7. The side parts 3 are also fixed at the top with non-positive connections on the frame 2, usually with screw connections that can be secured against unauthorized access with locks. As in the case of the upper part 4, these fixations are designed in such a way that they do not loosen even under the application of considerable force, but at most deform.

Fig. 3 zeigt eine schematische Darstellung der seitlichen Befestigungen 8. Beispielhaft werden hier Haken verwendet, die im Falle einer Krafteinwirkung aus der Richtung der Innenseite leicht verformbar sind oder abreißen können und das Seitenteil freigeben. Die Haken sind dabei am Rahmen befestigt. Die Anzahl dieser seitlichen Einhakungen hängt von der Größe der jeweiligen Außenbox ab, einer Vielzahl kleiner Einhakungen ist der Vorzug zu geben. Sofern die Haken als Sollbruchstelle zum Abreißen dimensioniert werden, sollten sie an den Seitenteilen 3 befestigt werden, während am Rahmen die Aufhängung für die Haken eingerichtet ist. Fig. 3 shows a schematic representation of the lateral fastenings 8. As an example, hooks are used here that are easily deformable or can tear off in the event of a force being exerted from the direction of the inside and release the side part. The hooks are attached to the frame. The number of these side hooks depends on the size of the respective outer box, a large number of small hooks is preferred. If the hooks are dimensioned as a predetermined breaking point for tearing off, they should be attached to the side parts 3, while the suspension for the hooks is set up on the frame.

Fig. 4 zeigt eine schematische Darstellung der unterseitigen Befestigungen 9. Beispielhaft wird hier ein Absatz bzw. eine Fase am Seitenteil 3 vorgesehen, wobei das Seitenteil 3 lediglich lose in den Rahmen 2 eingesteckt wird. Ferner weist die unterseitige Befestigung einen Sensor auf 10 auf, der solange ein Signal erzeugt, wie sich das Seitenteil an der vorgesehenen Stelle am Rahmen befindet und beim Ausbleiben dieses Signals einen Alarm auslöst. Ein solcher Sensor kann beispielsweise durch ein RFID-Elementpaar gebildet sein, welches am Rahmen und unter der Fase am Seitenteil angebracht ist, Fig. 4 shows a schematic representation of the fastenings 9 on the underside. As an example, a shoulder or a chamfer is provided on the side part 3, the side part 3 being merely inserted loosely into the frame 2. Furthermore, the fastening on the underside has a sensor 10, which generates a signal as long as the side part is at the intended location on the frame and triggers an alarm if this signal fails to appear. Such a sensor can be formed, for example, by a pair of RFID elements, which is attached to the frame and under the bevel on the side part,

Falls nun ein Überdruckereignis stattfindet, beult sich zuerst das Seitenteil 3 etwas aus. Dabei reißen wenigstens einige der seitlichen Befestigungen, was beides Energie absorbiert. Durch die Verkürzung des Seitenteils 3 wird das Seitenteil 3 aus der unteren Befestigung 9 herausgezogen, und der Sensor erzeugt ein Signal, welches als Alarmsignal gewertet werden kann. Im weiteren Verlauf des Überdruckereignisses kann sich das Seitenteil 3 nach außen biegen, wobei im unteren Bereich eine Öffnung entsteht, die groß genug zum Abbau des Überdrucks ist. Durch die Biegung des Seitenteils nach außen wird weitere Energie als Verformungsenergie absorbiert.If an overpressure event now takes place, the side part 3 first bulges out a little. At least some of the side fastenings tear, both of which absorb energy. By shortening the side part 3, the side part 3 is pulled out of the lower fastening 9, and the sensor generates a signal which can be interpreted as an alarm signal. In the further course of the overpressure event, the side part 3 can bend outwards, an opening being created in the lower area that is large enough to reduce the overpressure. By bending the side part outwards, further energy is absorbed as deformation energy.

Es kann weiterhin vorgesehen werden, dass die Seitenteile durch Prägungen, Biegungen und Anbringung von Formteilen so verstärkt werden, dass sie während des Öffnungsvorgangs weitere Energie in Form von Verformungsenergie aufnehmen können. Der Widerstand, den die Seitenteile dem Aufbiegungsvorgang entgegensetzen, darf dabei aber nicht so groß werden, dass Oberseite, Frontseite oder Rückseite beschädigt werden. Im Falle einer Verstärkung der Seitenteile sind daher die übrigen Tele ebenfalls entsprechend zu verstärken.It can also be provided that the side parts are reinforced by embossing, bending and attaching molded parts so that they can absorb further energy in the form of deformation energy during the opening process. The resistance that the side parts oppose the bending process must not be so great that the top, front or back is damaged. In the case of a reinforcement of the side parts, the other telephoto should also be reinforced accordingly.
