Abstract

The charging device comprises a stool-like frame construction (12) into which a cube-shaped housing (1) is inserted approximately one metre from the floor, the housing containing a heat pump, a blower (fan) and other accessories. The housing (1) is made in the form of a cube and has, on the front wall (19), an air intake screen (21) and, on the two side walls (20, 20') and at the top on the cover, in each case air outlets (21) for the compressed air generated by a blower in the housing (1). The housing (1) is equipped with two connections (23, 24) for the supply of water to be heated and water which has been heated, and also with a dripping-water outlet (11) and a plug for connection to a control box (18). A major advantage of the device is the compact design of the housing and of the heat pump (1), which for a power of up to 5 kW has a side length of only 55 cm. Consequently, the housing (1) together with the contents is very light and can be exchanged by a single semi-skilled worker, thereby greatly facilitating the maintenance and repair of the device and of the heating installation. A defective unit, or a unit to be checked, can be replaced by a single person, e.g. by the caretaker, with the result that the loss of heating or hot water is of only very short duration. Since the exchanging operation does not require a heating specialist, considerable labour costs can be saved. Further advantages of the device are the dewatering action and hence the suitability as a linen drier, and also the cooling action, which is greatly appreciated especially in summer in the room in which the device is installed. <IMAGE>

Description

Die Erfindung betrifft eine Ladeeinrichtung für Speicher und Boiler gemäss dem Oberbegriff des ersten Patentanspruches.The invention relates to a charging device for storage and boiler according to the preamble of the first claim.

Bei dieser Einrichtung handelt es sich um ein Gehäuse mit eingebauter Wärmepumpe, die auf einer Rahmenkonstruktion mit den erforderlichen Anschlüssen und der sonstigen Installation montiert ist. Dabei wird eine normierte, d.h. nur in bestimmten Grössen angefertigte, kompakte Wärmepumpe zusammen mit einer entsprechend dimensionierten Rahmenkonstruktion benutzt, an welcher die gesamte Verrohrung mit Fittings, Armaturen, Thermometer, Regelventil, Antrieb, Umwälzpumpe und Steuerung mit Elektro-Steuerkasten aufgebaut ist.This device is a housing with a built-in heat pump, which is mounted on a frame construction with the necessary connections and other installation. A standardized, i.e. only used in certain sizes, compact heat pump together with an appropriately dimensioned frame construction, on which the entire piping with fittings, fittings, thermometer, control valve, drive, circulation pump and control with electrical control box is built.

Die Wärmepumpe ist für Luft/Wasser, Wasser/Wasser oder Sole/Wasser ausgelegt, wobei die heute bekannten Wärmepumpen gleicher Grösse die folgenden Ausführungen umfassen:The heat pump is designed for air / water, water / water or brine / water, whereby the heat pumps of the same size known today include the following versions:

Bei einer ersten Ausführung ist das Wärmepumpenaggregat mit einem Warmwasser-Boiler direkt verbunden und wird entweder oben darauf oder seitlich zu diesem angeordnet und ist unter dem Begriff WP-Boiler bekannt.In a first embodiment, the heat pump unit is directly connected to a hot water boiler and is arranged either on top of it or laterally to it and is known under the term HP boiler.

Bei diesem Verfahren sorgt eine Heizspirale, welche direkt in den Boiler eintaucht und ausserhalb desselben mit der Wärmepumpe gekoppelt ist, für die Erwärmung des Warmwassers.In this process, a heating spiral, which plunges directly into the boiler and is coupled to the heat pump outside it, heats the hot water.

Diese Lösung hat den grossen Nachteil, dass im Boiler keine Temperatur-Schichtung von oben nach unten möglich ist, da die Heizspirale eine solche aus physikalischen Gründen nicht zulässt.This solution has the major disadvantage that temperature stratification from top to bottom is not possible in the boiler, since the heating coil does not allow such a stratification for physical reasons.

Ein weiterer Nachteil dieses Verfahrens besteht darin, dass bei einer Störung oder einem Defekt der Wärmepumpe, ein Kältefachmann von der Lieferfirma beigezogen werden muss, da diese Arbeit nicht vom Hauswart selbst oder von einem Sanitärfachmann ausgeführt werden kann. Auch sind Reparaturen an der Anlage mit grossem Zeitaufwand verbunden, so dass hohe Reparaturkosten entstehen. Es ist auch nicht möglich, mit einer Austausch-Wärmepumpe zu arbeiten, weil ein Austausch nicht schnell genug durchführbar ist.Another disadvantage of this method is that in the event of a malfunction or a defect in the heat pump, a refrigeration specialist from the supplier must be consulted because this work cannot be carried out by the caretaker himself or by a sanitary specialist. Repairs to the system are also time-consuming, so that high repair costs are incurred. It is also not possible to work with an exchange heat pump because an exchange cannot be carried out quickly enough.

Bei einer zweiten herkömmlichen Ausführung ist die Wärmepumpe eine selbstständige Einheit, die über zwei Metallschläuche mit dem Wärmepumpe-Boiler, d.h. einmal unten und einmal oben, verbunden ist, wobei ein druckgesteuertes Drosselventil die Wassermenge und somit die Wassertemperatur reguliert.In a second conventional embodiment, the heat pump is an independent unit which is connected to the heat pump boiler via two metal hoses, i.e. once below and once above, is connected, with a pressure-controlled throttle valve regulating the amount of water and thus the water temperature.

Ein Nachteil dieser Ausführung ist darin begründet, dass solche Wärmepumpen relativ gross sind und dementsprechend viel Platz benötigen. Ferner arbeitet diese Ausführung mit dem Kältemittel R22, weshalb das Wasser im Boiler nicht auf 60, sondern lediglich auf 50°C erwärmt werden kann. Eine weitere wichtige Aufgabe, nämlich die in einer Installation auftretenden Zirkulationsverluste preisgünstig via einer Wärmepumpe abzudecken, ist bei dieser Ausführung nicht möglich, so dass die Zirkulationsverluste heute bei vielen Installationen mittels Begleitheizung abgedeckt werden, was bezüglich der Kosten und des Stromverbrauches sehr unwirtschaftlich ist.A disadvantage of this design is that such heat pumps are relatively large and therefore take up a lot of space. Furthermore, this version works with the refrigerant R22, which is why the water in the boiler can not be heated to 60, but only to 50 ° C. Another important task, namely to cover the circulation losses in an installation inexpensively via a heat pump, is not possible with this version, so that the circulation losses are covered by trace heating in many installations today, which is very uneconomical in terms of costs and electricity consumption.

Ein weiterer Nachteil besteht darin, dass diese Anlagen erst auf dem Bau zusammengesetzt werden können oder müssen, was zu einem erhöhten Arbeitsaufwand auf dem Bau und deshalb zu höheren Investitionskosten führt. Auch kann die Ladepumpe nicht gleichzeitig als Zirkulations-Umwelzpumpe eingesetzt werden.Another disadvantage is that these systems can or must only be assembled on site, which leads to an increased workload on the site and therefore to higher investment costs. The charging pump cannot be used as a circulation environmental pump at the same time.

Zudem sind die heute auf dem Markt erhältlichen Wärmepumpe-Anlagen der oben beschriebenen Art lediglich bis zu einer Heizleistung von ca. 2.5 kW erhältlich und somit in ein Gesamtsystem punktuell nicht einsetzbar, weshalb sie nicht für grössere Wohnbauten geeignet sind.In addition, the heat pump systems of the type described above that are available on the market today are only available up to a heating output of approx. 2.5 kW and are therefore not suitable for use in an overall system, which is why they are not suitable for larger residential buildings.

Aufgabe der Erfindung ist es somit, eine Ladeeinrichtung bzw. eine Wärmepumpeanlage zu schaffen, welche die beschriebenen Nachteile der herkömmlichen Ausführungen nicht aufweist.The object of the invention is therefore to provide a charging device or a heat pump system which does not have the disadvantages of the conventional designs described.

Die zu schaffende Wärmepumpe soll z.B. in Anlagen derjenigen Art eingesetzt werden können, welche in EP-B-0 227 051 beschrieben sind.The heat pump to be created should e.g. can be used in systems of the type described in EP-B-0 227 051.

Dabei soll die Wärmepumpe gegenüber bestehenden Ausführungen insbesondere die folgenden Vorteile aufweisen:

  • eine normierte, d.h. in bestimmten Abmesssungen angefertigte Rahmenkonstruktion, an welcher die gesamte Verrohrung, Leitungen, Armaturen, Fittings, Thermometer, Dreiwege-Mischventil mit Antrieb, Regler, Pumpe und Elektro-Steuerkasten montiert sind, und entweder freistehend in einem Raum aufgestellt oder an einer Wand montiert werden kann und nur leitungsseitig mit dem Boiler verbunden werden muss,
  • eine normierte, würfelförmige, sehr leichte, handliche und in den Abmessungen möglichst kleine, für verschiedene Leistungen ausgelegte Wärmepumpe, die mit wenigen Handgriffen auf die vorgängig montierte Rahmenkonstruktion aufsetzbar ist und nach dem Verbinden von zwei Verschraubungen und dem Einstecken eines elektrischen Kabels fertig montiert und betriebsbereit ist,
  • sie soll bei zu kleiner Leistung oder bei einer Störung, vom Betreiber selbst oder einer Hilfsperson in wenigen Minuten ausgetauscht werden können,
  • es sollen keine Reparaturen an Ort und Stelle erforderlich sein, sondern nur mit Austauschaggregaten gearbeitet werden, was den Service und den Austausch von Wärmepumpen überhaupt und insbesondere in abgelegenen Gegenden bzw. Berggegenden, wesentlich erleichtert,
  • die Wärmepumpe soll mit einem umweltfreundlichen FCKW-freien Kältemittel betrieben werden können und eine Wassertemperatur von minedestens 60°C erreichen,
  • die Wärmepumpe soll anstelle der Begleitheizung zur Deckung der Zirkulationsverluste eingesetzt werden, was zu hohen Einsparungen an Energie und daher zu einer sehr kurzen Amortisationszeit der Wärmepumpe führt,
  • eine oder mehrere Wärmepumpen sollen punktuell unabhängig voneinander vom Standort der Boiler oder Speicher systematisch zur Rückgewinnung überschüssiger Wärme, Klimatisierung von Räumen, sowie als Entfeuchtungsgerät im Keller, vor allem aber zur Betreibung als Wäschetrockner oder Wäschetrocknungsraum eingesetzt werden können,
  • die Rahmenkonstruktion mit der gesamten Verrohrung und dem Elektro-Steuerkasten wird anschlussfertig geliefert, so dass die Anlage von einem Arbeiter oder vom Hauswart in Betrieb genommen oder eingeschaltet werden kann.
The heat pump should have the following advantages over existing versions:
  • a standardized frame construction, i.e. manufactured in certain dimensions, on which the entire piping, lines, fittings, fittings, thermometer, three-way mixing valve with drive, controller, pump and electrical control box are mounted, and either set up free-standing in a room or on one Wall can be mounted and only needs to be connected to the boiler on the line side,
  • a standardized, cube-shaped, very light, handy and as small as possible heat pump designed for different capacities, which can be attached to the previously assembled frame construction in just a few steps and is fully assembled and ready for use after connecting two screw connections and inserting an electrical cable is
  • if the power is too low or in the event of a malfunction, it should be able to be replaced in a few minutes by the operator or an auxiliary person,
  • no on-site repairs should be required, but only work with replacement units, which greatly facilitates the service and replacement of heat pumps in general, particularly in remote or mountain areas,
  • the heat pump should be able to be operated with an environmentally friendly CFC-free refrigerant and should reach a water temperature of at least 60 ° C,
  • the heat pump should be used instead of the trace heating to cover the circulation losses, which leads to high energy savings and therefore to a very short payback period for the heat pump,
  • One or more heat pumps should be able to be used systematically for the recovery of excess heat, air conditioning of rooms, as well as a dehumidification device in the basement, but above all for operation as a clothes dryer or clothes drying room, regardless of the location of the boiler or storage,
  • the frame construction with the entire piping and the electrical control box is supplied ready for connection, so that the system can be commissioned or switched on by a worker or the caretaker.

Diese Aufgabe ist erfindungsgemäss durch die Merkmale des ersten Anspruches gelöst.According to the invention, this object is achieved by the features of the first claim.

Ausführungsformen sind in den abhängigen Ansprüchen umschrieben.Embodiments are described in the dependent claims.

Es hat sich dabei herausgestellt, dass aufgrund der Abmessungen ein würfelförmiges Gehäuse am besten geeignet ist, die Zu- und Abluftzufuhr, den Kompressor und den Verdampfer in einem möglichst kleinen Gehäuse unterzubringen, dessen Grösse für verschiedene Leistungen festgelegt ist, und immer die gleichen Seitenlängen aufweist.It turned out that due to the dimensions, a cube-shaped housing is best suited to accommodate the supply and exhaust air supply, the compressor and the evaporator in a housing that is as small as possible, the size of which is fixed for different outputs, and always has the same side lengths .

So beträgt die Seitenlänge bei Heizleistungen bis zu 5 kW nur 55 cm, was gegenüber den bisherigen Ausführungen eine gewaltige Reduktion der Masse bedeutet.The side length for heating capacities up to 5 kW is only 55 cm, which is a huge compared to the previous versions Reduction in mass means.

Oben ist das Gehäuse der Wärmepumpe 1 an den beiden Verschraubungen oder Rohren 13 und 14 und unten an einer Tropfwasserleitung 11 angeschlossen, wobei das eine Rohr 13 mit einem von einem Antrieb 3 gesteuerten Mischventil 2 verbunden ist. Dieses Mischventil 2 bezieht Wasser aus zwei verschiedenen Schichten eines Speichers 15 und liefert die vom Antrieb 3 bestimmte Wassermischung an die im Gehäuse 1 untergebrachte, nicht gezeigte Wärmepumpe ab. Vom Kondensator der Wärmepumpe 1 fliesst das erwärmte Wasser durch das Rohr 14 in das Leitungsnetz einerseits und anderseits ein Teil davon in den Boiler oder Speicher 15.The housing of the heat pump 1 is connected at the top to the two screw connections or pipes 13 and 14 and at the bottom to a drip water line 11, the one pipe 13 being connected to a mixing valve 2 controlled by a drive 3. This mixing valve 2 draws water from two different layers of a reservoir 15 and delivers the water mixture determined by the drive 3 to the heat pump (not shown) accommodated in the housing 1. The heated water flows from the condenser of the heat pump 1 through the pipe 14 into the pipe network on the one hand and on the other hand a part thereof into the boiler or storage tank 15.

Das Gehäuse 1 ist auf die Rahmenkonstruktion 12 aufgebaut und besteht aus einer selbstständigen Wärmepumpeneinheit, die auf der Rückseite mit zwei Anschlüssen für die beiden Rohre 13 und 14 sowie für die Tropfwasserleitung 11 versehen ist. Ferner ist das Gehäuse 1 mit einem Anschluss über einen flexiblen Kunststoff- oder Gummischlauch mit der Tropfwasserleitung 11 verbunden. Zudem ist ein Elektrokabel mit Stecker am Gehäuse 1 für die Verbindung zum Steuerkasten 18 vorhanden.The housing 1 is built on the frame structure 12 and consists of an independent heat pump unit, which is provided on the rear with two connections for the two pipes 13 and 14 and for the drip water line 11. Furthermore, the housing 1 is connected to the drip water line 11 with a connection via a flexible plastic or rubber hose. There is also an electrical cable with a plug on the housing 1 for the connection to the control box 18.

The air is blown back into the room through three air grilles 21 on the adjoining side walls 20, 20 'and at the top of the housing.

In den Fig. 5 bis 8 ist der Einsatz der Speicherladeeinrichtung in verschiedenen Warmwasseranlagen dargestellt, wobei in Fig. 5, 7 und 8 nur ein Boiler, dagegen in Fig. 6 zwei Boiler verwendet werden. Die Fig. 5 und 6 zeigen jeweils eine Wärmepumpe 1, während in den Fig. 7 und 8 jeweils drei Wärmepumpen 1 benutzt werden, die parallelgeschaltet sind. Im Falle der Fig. 7 ist den einzelnen Wärmepumpen 1 jeweils eine Gruppe von Zapfstellen 27 zugeordnet, während im Fig. 8 alle Wärmepumpen 1 zusammen eine Gruppe von Zapfstellen 27 speisen. Die Fig. 5 bis 8 zeigen ferner jeweils eine Zirkulationspumpe 28, ein Ein- und Ausschalt-Thermometer 29 und ein Passtück bzw. Verbindung 30. Zudem ist ein Rückschlagsventil 31 vorhanden.5 to 8 show the use of the accumulator charging device in various hot water systems, only one boiler being used in FIGS. 5, 7 and 8, whereas two boilers are used in FIG. 6. 5 and 6 each show a heat pump 1, while in FIGS. 7 and 8 three heat pumps 1 are used, which are connected in parallel. In the case of FIG. 7, a group of tapping points 27 is assigned to each of the individual heat pumps 1, while in FIG. 8 all the heat pumps 1 feed together a group of tapping points 27. 5 to 8 each show a circulation pump 28, an on and off thermometer 29 and a fitting or connection 30. In addition, a check valve 31 is provided.

Die verschiedenen Ausführungen werden je nach Bedarf eingesetzt, der vom Wasserverbrauch an den einzelnen Zapfstellen abhängt.The different versions are used as required, which depends on the water consumption at the individual taps.

Die Speicherladeeinrichtung ist nicht nur auf diesem Gebiet, sondern auch als Trocknungsgerät oder als Entfeuchter, vor allem im Keller, wo sie aufgestellt ist, sehr wirksam. Diese Nebenwirkung hat sich als vieleicht der grösste Vorteil der vorliegenden Ausführung im Vergleich zu bestehenden Einrichtungen erwiesen. Infolge der entfeuchtenden Wirkung der Einrichtung, insbesondere im Kellerbereich, eignet sie sich auch als Wäschetrockner. Die Speicherladeeinrichtung hat somit die folgenden drei zusätzlichen Eigenschaften, welche alle vorteilhaft sind und mit keinen Nachteilen verbunden sind:

  • a) sie erzeugt Warmwasser,
  • b) sie entfeuchtet die Umgebungsluft, was zur schnellen Trocknung von Wäsche führt, die im gleichen oder einem benachbarten Raum aufgehängt ist, und
  • c) sie kühlt schliesslich die Umgebungsluft, weshalb sie als Klimaanlage einsetzbar ist.
The storage charging device is very effective not only in this area, but also as a drying device or as a dehumidifier, especially in the basement where it is installed. This side effect has proven to be perhaps the greatest advantage of the present design compared to existing facilities. Due to the dehumidifying effect of the device, especially in the basement area, it is also suitable as a tumble dryer. The storage charging device thus has the following three additional properties, all of which are advantageous and have no disadvantages:
  • a) it produces hot water,
  • b) it dehumidifies the ambient air, which leads to the rapid drying of laundry which is hung in the same or an adjacent room, and
  • c) it finally cools the ambient air, which is why it can be used as air conditioning.

Alle diese Vorteile zusammen macht sie für den Einsatz in Einfamilien-, Mehrfamilienhäusern sowie in Fabriken besonders gut geeignet, in welchen auf eine trockene und kühle Luft Wert gelegt wird. Falls auf Klima- und Entfeuchterwirkung keinen grossen Wert gelegt wird, was in einem kalten trockenen Winter u.u. möglich ist, kann die gekühlte Luft nach aussen in die Umgebungsluft abgeleitet werden.All of these advantages together make them particularly well suited for use in single-family and multi-family houses, as well as in factories where dry and cool air is important. If the climate and dehumidifier effect is not very important, which may be the case in a cold dry winter. is possible, the cooled air can be discharged outside into the ambient air.

Die grössten Vorteile der vorliegenden Ausführung sind u.a. die geringen Abmessungen, die kompakte Bauweise, der geräuscharme Betrieb, und das niedrige Gewicht des Gehäuses 1 mit Inhalt. Bei einer Störung oder einem Ausfall der Wärmepumpe, kann sie in wenigen min. ausgetauscht werden, indem lediglich die beiden Verschraubungen 13,14 am Gehäuse gelöst werden und der Stecker am Elektro-Steuerkasten 18 ausgezogen wird. Diese schnelle und einfache Austauschmöglichkeit macht es möglich, das Gerät von einem Arbeiter oder Hauswart austauschen zu lassen, wobei kein Heizungsmonteur benötigt wird. Somit kann die Dauer eines Unterbruchs bei einem Ausfall der Wärmepumpe auf eine Mindestdauer reduziert werden, was gegenüber bisherigen Ausführungen einen sehr grossen Vorteil darstellt. Die beschriebene Speicherladeeinrichtung ist u.a. für Verwendung zusammen mit derjenigen Wärmepumpeneinrichtung vorgesehen, welche in der EP-B-0 227 051 offenbart ist.The greatest advantages of the present embodiment include the small dimensions, the compact design, the low-noise operation, and the low weight of the housing 1 with content. In the event of a malfunction or failure of the heat pump, it can be carried out in a few minutes. can be replaced by simply loosening the two screw connections 13, 14 on the housing and the plug on the electrical control box 18 is pulled out. This quick and easy exchange option makes it possible to have the device replaced by a worker or caretaker, without the need for a heating technician. The duration of an interruption in the event of a heat pump failure can thus be reduced to a minimum, which is a very great advantage over previous designs. The storage charging device described is intended, inter alia, for use together with that heat pump device which is disclosed in EP-B-0 227 051.
