Die vorliegende Erfindung betrifft eine Temperierungsanordnung mit einem inneren Temperierungskreislauf und zwei äußeren Temperierungskreisläufen, wobei der innere Temperierungskreislauf eine Wärme abgebende Schnittstelle und eine Kälte abgebende Schnittstelle aufweist, und wobei die zwei äußeren Temperierungskreisläufe jeweils mit einer Schnittstelle thermisch gekoppelt sind. Sie dient z. B. dem Erwärmen oder Abkühlen von Raumluft oder dem Bereitstellen von heißem Wasser. The present invention relates to a temperature control arrangement with an inner temperature control circuit and two outer temperature control circuits, the inner temperature control circuit having a heat-emitting interface and a cold-emitting interface, and the two outer temperature control circuits each being thermally coupled to an interface. It serves e.g. B. the heating or cooling of room air or the provision of hot water.

Im Stand der Technik ist es bekannt, dass bei Elektrofahrzeugen die Wärme des Motors und insbesondere der Batterie abgeführt wird. Im Sinne der Ökologie lässt sich diese Wärme beispielweise für eine Heizung im Fahrzeug verwenden. Daher sind Thermomanagementsysteme für Elektro- oder Hybridfahrzeugen bekannt, die über Solekreisläufe mit der Wärme von Batterie, Inverter und Elektromotor den Fahrgastraum klimatisieren. It is known in the prior art that the heat from the motor and in particular from the battery is dissipated in electric vehicles. In terms of ecology, this heat can be used for heating in the vehicle, for example. Thermal management systems for electric or hybrid vehicles are therefore known, which air-condition the passenger compartment via brine circuits with the heat from the battery, inverter and electric motor.

Gekoppelte Temperierungskreisläufe finden sich beispielsweise offenbart in der DE 10 2007 018439 B3, der DE 10 2004 007 932 A1 , der GB 2 566 381 A oder der EP 0431 760 A1. Eine Kopplung eines Kreislaufs mit dem Motor eines Elektrofahrzeugs zeigt die DE 10 2016 015 256 A1. Coupled temperature control circuits are disclosed, for example, in DE 10 2007 018439 B3, DE 10 2004 007 932 A1, GB 2 566 381 A or EP 0431 760 A1. DE 10 2016 015 256 A1 shows how a circuit is coupled to the motor of an electric vehicle.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine Temperierungsanordnung vorzuschlagen, die die in einem System zur Verfügung stehende bzw. erzeugte Energie möglichst optimal ausnutzt. The object on which the invention is based is to propose a temperature control arrangement which utilizes the energy available or generated in a system as optimally as possible.

Die Erfindung löst die Aufgabe mit einer Temperierungsanordnung, die dadurch gekennzeichnet ist, dass die Temperierungsanordnung ferner einen Flüssigkeitserhitzer zum Erhitzen von Brauchwasser aufweist, und dass einer der zwei äußeren Temperierungskreisläufe mit dem Flüssigkeitserhitzer thermisch gekoppelt ist. The invention solves the problem with a temperature control arrangement, which is characterized in that the temperature control arrangement also has a liquid heater for heating service water, and that one of the two outer temperature control circuits is thermally coupled to the liquid heater.

Bei der Temperierungsanordnung sind drei Temperierungskreisläufe vorgesehen. Der innere Kreislauf produziert einerseits Wärme und andererseits Kälte. Die Wärme und die Kälte lassen sich jeweils über eine Schnittstelle abgreifen. Daher sind die zwei separaten äußeren Temperierungskreisläufe jeweils thermisch mit den Schnittstellen gekoppelt. Somit Three temperature control circuits are provided in the temperature control arrangement. The inner cycle produces heat on the one hand and cold on the other. The heat and the cold can each be tapped off via an interface. Therefore, the two separate external temperature control circuits are each thermally coupled to the interfaces. Consequently

BESTÄTIGU GSKOPE wird also von einem Kreislauf Wärme und Kälte abgegriffen, um diese jeweils in den beiden nachgeordneten Kreisläufen optimal zu verwenden. CONFIRM GSKOPE heat and cold are tapped from a circuit in order to use them optimally in the two downstream circuits.

Erfindungsgemäß ist eine thermische Kopplung zwischen einem äußeren Temperierungskreislauf und einem Flüssigkeitserhitzer gegeben. Somit wird also die Wärme, die der innere Temperierungskreislauf erzeugt, z. B. zum Erhitzen von Wasser verwendet. Der betroffene äußere Temperierungskreislauf ist vorzugsweise derjenige, der mit der Wärme abgebenden Schnittstelle des inneren Temperierungskreislaufs gekoppelt ist. Der Flüssigkeitserhitzer ist in einer Ausgestaltung ein Wassererhitzer. According to the invention, there is thermal coupling between an external temperature control circuit and a liquid heater. Thus, the heat generated by the internal temperature control circuit, e.g. B. used to heat water. The affected external temperature control circuit is preferably the one that is coupled to the heat-dissipating interface of the internal temperature control circuit. In one embodiment, the liquid heater is a water heater.

Eine Ausgestaltung sieht vor, dass die thermische Kopplung zwischen den äußeren Temperierungskreisläufen und den Schnittstellen jeweils über einen Wärmetauscher erfolgt. One embodiment provides for the thermal coupling between the external temperature control circuits and the interfaces to take place via a heat exchanger in each case.

Eine Ausgestaltung beinhaltet, dass der innere Temperierungskreislauf als Kühlkreislauf mit einem Kühlmittel realisiert ist. Solche Kühlkreisläufe sind bei der Anwendung in Klimaanlagen bekannt. Das Prinzip ist beispielsweise in der WO 2007/042065 A1 beschrieben. Ein solcher Kühlkreislauf verfügt zumeist über zwei Wärmetauscher. Über einen Wärmetauscher wird als Teil des Verdampfers Kälte auf das zu kühlenden Medium übertragen. Der andere Wärmetauscher gehört zu dem Verflüssiger und dient der Abführung von Wärme. Weiterhin sind ein Kompressor (eine alternative Bezeichnung ist Verdichter) sowie eine Expansionseinrichtung vorhanden und zwischen dem Verdampfer und dem Verflüssiger angeordnet. One configuration includes that the inner temperature control circuit is implemented as a cooling circuit with a coolant. Such cooling circuits are known for use in air conditioning systems. The principle is described, for example, in WO 2007/042065 A1. Such a cooling circuit usually has two heat exchangers. As part of the evaporator, cold is transferred to the medium to be cooled via a heat exchanger. The other heat exchanger belongs to the condenser and is used to dissipate heat. Furthermore, a compressor (an alternative term is compressor) and an expansion device are present and arranged between the evaporator and the condenser.

Eine Ausgestaltung sieht vor, dass das Kühlmittel CO2 ist. Der innere Temperierungskreislauf ist in dieser Ausgestaltung somit ein CO2-Kühlkreislauf. Die Verwendung von CO2 erlaubt es, sehr hohe Temperaturen zu erzeugen, indem der innere Temperierungskreislauf überkritisch betrieben wird. Die hohen Temperaturen (vorzugsweise höher als 70 °C) sind beispielsweise erforderlich, wenn Brauchwasser ausreichend erhitzt werden soll (beispielsweise in Bezug auf die Abtötung von Legionellen). One embodiment provides that the coolant is CO2. In this embodiment, the inner temperature control circuit is therefore a CO2 cooling circuit. The use of CO2 allows very high temperatures to be generated by supercritically operating the internal temperature control circuit. The high temperatures (preferably higher than 70 °C) are required, for example, if service water is to be heated sufficiently (e.g. with regard to killing legionella).

Eine Ausgestaltung beinhaltet, dass die zwei äußeren Temperierungskreisläufe jeweils als Solekreisläufe realisiert sind. In einem Solekreislauf wird beispielsweise eine Mischung aus Wasser und einem Frostschutzmittel (beispielsweise Kohlenwasserstoffverbindungen wie Methanol, Ethanol oder Glycerin) zirkuliert, um Wärme (oder Kälte) von einem Bereich zu einem anderen zu transportieren. One embodiment includes that the two outer temperature control circuits are each implemented as brine circuits. In a brine circuit, for example, a mixture of water and an antifreeze (e.g. hydrocarbon compounds such as methanol, ethanol or glycerin) circulates to transport heat (or cold) from one area to another.

Alternativ oder ergänzend ist der angesprochene und mit der Wärme abgebenden Schnittstelle gekoppelte äußere Temperierungskreislauf noch mit Wärme abgebenden Radiatoren gekoppelt. Alternatively or additionally, the external temperature control circuit mentioned and coupled to the heat-emitting interface is also coupled to heat-emitting radiators.

Eine Ausgestaltung besteht darin, dass die Temperierungsanordnung ferner ein Kühlbehältnis - insbesondere in Form eines Kühlschranks - aufweist, und dass ein äußerer Temperierungskreislauf mit dem Kühlbehältnis thermisch gekoppelt ist. In dieser Ausgestaltung überträgt der äußere Temperierungskreislauf, der mit der Kälte abgebenden Schnittstelle des inneren Temperierungskreislaufs thermisch gekoppelt ist, die Kälte auf ein Kühlbehältnis. Das Kühlbehältnis ist beispielweise ein Kühlschrank. One configuration is that the temperature control arrangement also has a refrigerated container—in particular in the form of a refrigerator—and that an external temperature control circuit is thermally coupled to the refrigerated container. In this embodiment, the outer temperature control circuit, which is thermally coupled to the cold-emitting interface of the inner temperature control circuit, transfers the cold to a refrigerated container. The cooling container is a refrigerator, for example.

Der die Kälte führende äußere Temperierungskreislauf ist in einer alternativen oder ergänzenden Ausgestaltung mit weiteren Radiatoren oder der Kühlung von Luft vorgesehenen Komponenten thermisch gekoppelt. In an alternative or supplementary configuration, the external temperature control circuit carrying the cold is thermally coupled to further radiators or components provided for cooling air.

In einer Ausgestaltung sind die äußeren Temperierungskreisläufe mit den Wärme bzw. Kälte verwendenden Komponenten (z. B. Wassererhitzer, Luftauslass oder Kühlbehältnis) mittelbar (z. B. über einen Wärmetauscher) thermisch gekoppelt. In one embodiment, the external temperature control circuits are thermally coupled indirectly (eg via a heat exchanger) to the components that use heat or cold (eg water heater, air outlet or cooling container).

In einer alternativen Ausgestaltung strömt das in dem jeweiligen äußeren Temperierungskreislauf bewegte Transportmedium direkt durch die jeweilige Komponente hindurch. Ein Beispiel hierfür ist das Strömen einer Sole durch einen Heizkörper. Eine angeschlossene Komponente ist beispielsweise eine Fußbodenheizung, über die die Wärme abgegeben wird. Eine weitere Komponente dient beispielsweise der Entfeuchtung der Raumluft. In an alternative embodiment, the transport medium moved in the respective outer temperature control circuit flows directly through the respective component. An example of this is the flow of brine through a radiator. A connected component is, for example, underfloor heating, through which the heat is emitted. Another component is used, for example, to dehumidify the room air.

In einer Ausgestaltung wird insgesamt ein sogenanntes 3-in-1 -System realisiert, indem eine Raumheizung, eine Klimaanlage und ein Warmwasserbereiter durch das eine System gegeben sind. In one embodiment, a so-called 3-in-1 system is implemented overall, in that space heating, air conditioning and a water heater are provided by one system.

Gemäß einer Ausgestaltung weist mindestens ein äußerer Temperierungskreislauf einen Ausgleichswärmetauscher auf, wobei der Ausgleichswärmetauscher derartig ausgestaltet ist, dass er in dem Fall, dass sich in dem zugeordneten äußeren Temperierungskreislauf eine über einen vorgebbaren Grenzwert hinausgehende Menge an Wärme oder Kälte befindet, Wärme bzw. Kälte aus dem äußeren Temperierungskreislauf abführt. In dieser Ausgestaltung ist somit in mindestens einem der äußeren Temperierungskreisläufe eine Art von Überdruckventil vorhanden, das ein Übermaß an Wärme oder Kälte abführt. Wird somit an den äußeren Temperierungskreislauf zu viel Wärme oder Kälte übertragen, so erlaubt der Ausgleichswärmetauscher die Abgabe dieser zusätzlichen Wärm- bzw. Kältemenge. Dies geschieht z. B. an die Abgabe an die Umwelt oder an die Luft. According to one embodiment, at least one external temperature control circuit has a compensating heat exchanger, with the compensating heat exchanger being designed in this way is that it dissipates heat or cold from the external temperature control circuit in the event that there is a quantity of heat or cold in excess of a predefinable limit value in the associated external temperature control circuit. In this embodiment, at least one of the outer temperature control circuits has a type of pressure relief valve that dissipates excess heat or cold. If too much heat or cold is thus transferred to the external temperature control circuit, the compensating heat exchanger allows this additional quantity of heat or cold to be released. This happens e.g. B. to the discharge into the environment or into the air.

Eine Ausgestaltung sieht vor, dass der innere Temperierungskreislauf mit einem Elektromotor eines Fahrzeugs thermisch koppelbar ist. Die Kopplung erfolgt dabei insbesondere mit dem Zweck, die Wärme der Batterie des Elektromotors abzuführen. One embodiment provides that the inner temperature control circuit can be thermally coupled to an electric motor of a vehicle. The coupling takes place in particular with the purpose of dissipating the heat from the battery of the electric motor.

Eine Ausgestaltung besteht darin, dass die Temperierungsvorrichtung für die Anwendung in einem Wohnmobil oder einem Wohnwagen ausgestaltet ist. One embodiment is that the temperature control device is designed for use in a mobile home or caravan.

Im Einzelnen gibt es eine Vielzahl von Möglichkeiten, die erfindungsgemäße Temperierungsanordnung auszugestalten und weiterzubilden. Dazu wird verwiesen einerseits auf die dem Patentanspruch 1 nachgeordneten Patentansprüche, andererseits auf die folgende Beschreibung von Ausführungsbeispielen in Verbindung mit der Zeichnung. Es zeigt: In detail, there are a number of possibilities for embodying and developing the temperature control arrangement according to the invention. For this purpose, reference is made on the one hand to the patent claims subordinate to patent claim 1 and on the other hand to the following description of exemplary embodiments in conjunction with the drawing. It shows:

Fig. 1 eine schematische Darstellung einer Temperierungsanordnung. 1 shows a schematic representation of a temperature control arrangement.

Die Temperierungsanordnung 1 der Fig. 1 kann alternativ auch als Temperierungssystem bezeichnet werden. Alternatively, the temperature control arrangement 1 of FIG. 1 can also be referred to as a temperature control system.

Den Kern bildet der innere Temperierungskreislauf 10, in dem CO2 als Kältemittel verwendet wird. Das Kältemittel wird dabei durch einen Kompressor verdichtet und zu einem Verflüssiger bewegt. Der Verflüssiger ist damit hier Teil einer ersten Schnittstelle 11 des inneren Temperaturkreislaufs 10. Die Wärme des Kältemittels wird über einen ersten Wärmetauscher 31 auf den hier oben dargestellten ersten oder warmen äußeren Temperierungskreislauf 21 übertragen. Das infolge der Wärmeabgabe verflüssigte Kältemittel gelangt im inneren Temperierungskreislauf 10 zu einer Expansionseinrichtung, die z. B. als Drossel ausgestaltet ist, und dann zu einem Verdampfer, der somit von der zweiten Schnittstelle 12 umfasst wird. Die Kälte wird über einen zweiten Wärmetauscher 32 auf den hier zeichnerisch unten dargestellten zweiten oder kalten äußeren Temperierungskreislauf 22 übertragen. The core is the inner temperature control circuit 10, in which CO2 is used as a refrigerant. The refrigerant is compressed by a compressor and transported to a condenser. The condenser is thus part of a first interface 11 of the inner temperature circuit 10. The heat of the refrigerant is transferred via a first heat exchanger 31 to the first or warm outer temperature control circuit 21 shown here above. The refrigerant liquefied as a result of the heat dissipation arrives in the inner temperature control circuit 10 at an expansion device z. B. is designed as a throttle, and then to an evaporator, which is thus comprised of the second interface 12. The cold is transferred via a second heat exchanger 32 to the second or cold outer temperature control circuit 22 shown in the drawing below.

In dem ersten und hier der Abführung der Wärme dienenden äußeren Temperierungskreislauf 10 sind mehrere Radiatoren angedeutet, über welche die Wärme abgeführt wird. Dabei handelt es sich beispielsweise um Heizkörper, die von dem über die Schnittstelle 11 erwärmten Übertragungsmittel durchströmt werden. Öder es handelt sich um eine Fußbodenheizung. Der erste Temperierungskreislauf 10 verfügt zudem noch über einen Flüssigkeitserhitzer 41 , der beispielsweise der Erhitzung von Brauchwasser dient. Für die Regelung der zugehörigen Komponenten des ersten äußeren Temperierungskreislaufs 21 ist hier ein Ventil angedeutet, das das Übertragungsmittel in Richtung der Radiatoren bzw. des Flüssigkeitserhitzers 41 leitet. In the first outer temperature control circuit 10, which is used here to dissipate the heat, several radiators are indicated, via which the heat is dissipated. These are, for example, radiators through which the transfer medium heated via the interface 11 flows. Or it is underfloor heating. The first temperature control circuit 10 also has a liquid heater 41 which is used, for example, to heat process water. A valve is indicated here for controlling the associated components of the first external temperature control circuit 21 , which directs the transmission medium in the direction of the radiators or the liquid heater 41 .

Der zweite und der Abführung der Kälte dienende äußere Temperierungskreislauf 22 wird über einen eigenen Wärmetauscher 32 von der die Kälte abgebenden Schnittstelle 12 mit Kälte versorgt. Die Kälte wird dabei auf ein Übertragungsmittel übertragen, das als Sole ausgeführt ist, um ein Einfrieren zu verhindern. Diese Sole wird in dem zweiten äußeren Temperierungskreislauf 22 ebenfalls durch mehrere Radiatoren zum Abgeben der Kälte geführt. Zudem ist noch ein Kühlbehältnis 42 vorhanden, die hier als Kühlschrank ausgeführt und ebenfalls von der Sole gekühlt wird. The second external temperature control circuit 22 , which is used to remove the cold, is supplied with cold via its own heat exchanger 32 from the interface 12 emitting the cold. The cold is transferred to a transfer medium that is designed as a brine to prevent freezing. In the second external temperature control circuit 22, this brine is also passed through a plurality of radiators for discharging the cold. There is also a cooling container 42, which is designed here as a refrigerator and is also cooled by the brine.

Beide äußeren Temperierungskreisläufe 21 , 22 verfügen jeweils über einen Ausgleichswärmetauscher 51 , 52. Die Ausgleichswärmetauscher 51 , 52 dienen jeweils dazu, eine für den jeweiligen äußeren Temperierungskreislauf 21 , 22 zu große Menge an Wärme bzw. Kälte an die Umwelt abzugeben. Das Übermaß an Wärme bzw. Kälte im zugeordneten Kreislauf 21 , 22 ergibt sich beispielsweise, wenn die dem Kreislauf 21 , 22 zugeordneten Komponenten nicht betrieben werden oder eine geringere Menge an Wärme bzw. Kälte verbrauchen. Bezugszeichenliste Both outer temperature control circuits 21, 22 each have a compensating heat exchanger 51, 52. The compensating heat exchangers 51, 52 each serve to emit an excessive amount of heat or cold to the environment for the respective external temperature control circuit 21, 22. The excess of heat or cold in the associated circuit 21, 22 results, for example, when the components associated with the circuit 21, 22 are not operated or consume a smaller amount of heat or cold. reference list
