Verfahren zur Gewinnung von Heizwärme und Einrichtung zur Durchführung des VerfahrensProcess for obtaining heating heat and device for carrying out the process
Die Erfindung bezieht sich auf ein Verfahren zur Gewinnung von Heizwärme, bei dem einem durch Verdichten auf höhere Temperatur gebrachten, dampfförmigen Arbeitsmedium zur Heizzwecken Wärme entzogen wird, wobei das Medium kon¬ densiert, entspannt, verdampft und wieder verdichtet wird. Bei den bekannten Verfahren dieser Art wird die Verdampfung des Arbeitsmediums durch Zuführung von Wärme aus der Umgebung bewerkstelligt. Die Wärme wird hierbei der Umgebungsluft, dem Erdboden oder Gewässern entnommen. Die bekannten Verfahren sind jedoch dort nicht anwendbar, wo der Umgebung Wärme in nicht hinreichendem Ausmass ent¬ nommen werden kann, wie z. B. in Städten.The invention relates to a method for obtaining heating heat, in which heat is extracted from a vaporous working medium brought to a higher temperature by compression for heating purposes, the medium being condensed, expanded, evaporated and compressed again. In the known methods of this type, the evaporation of the working medium is accomplished by supplying heat from the environment. The heat is taken from the ambient air, the ground or water. However, the known methods cannot be used where heat cannot be removed from the surroundings to an adequate extent, such as, for example, B. in cities.
Aus der DE-OS 26 51 888 ist ein Verfahren bekannt, bei dem ein Teil des verdampften Arbeitsmediums dazu be¬ nützt wird, eine Turbine anzutreiben, die mit dem Ver¬ dichter gekoppelt ist. Hierbei wird jenem Teilstrom, dem die Nutzwärme entnommen werden kann, zum teilweisen Auf¬ heizen des die Turbine antreibenden Dampfes benützt. Die Verdampfung wird jedoch, wie bei den anderen bekannten Verfahren, ausschliesslich durch Fremdwärme herbeigeführt.From DE-OS 26 51 888 a method is known in which a part of the evaporated working medium is used to drive a turbine which is coupled to the compressor. In this case, the partial flow from which the useful heat can be taken is used to partially heat the steam driving the turbine. However, as with the other known methods, the evaporation is brought about exclusively by external heat.
Die Erfindung bezweckt die Schaffung eines Ver¬ fahrens, bei dem auf die Zuführung von Fremdwärme zum Ver¬ dampfen des Arbeitsmediums ganz oder teilweise verzichtet werden kann. Erfindungsgemäss wird dies so erreicht, dass die zum Verdampfen des entspannten Mediums erforderliche Wärme ganz oder teilweise dem verdichteten Medium entnom¬ men wird. Zweckmässigerweise wird für die Verdampfung des Arbeitsmediums mindestens ein Teil der bei dessen Konden¬ sation abgegebenen Wärme herangezogen.The invention aims to provide a method in which the supply of external heat to evaporate the working medium can be dispensed with in whole or in part. According to the invention, this is achieved in such a way that all or part of the heat required to evaporate the relaxed medium is removed from the compressed medium. At least part of the heat given off during its condensation is expediently used for the evaporation of the working medium.
Die Erfindung betrifft auch eine Einrichtung zur Durchführung des Verfahrens, bei welcher das Arbeitsmedium im Kreislauf von einem Verdampfer über einen Verdichter, Wärmetauscher und eine Drossel zum Verdampfer zurückge¬ führt wird. Erfindungsgemäss ist zwischen dem der Aufnahme der Heizwärme dienenden Wärmetauscher und der Drossel ein Kondensator angeordnet, der mit dem Verdampfer über den zusätzlichen Kreislauf eines Hilfsmediums verbunden ist.The invention also relates to a device for carrying out the method, in which the working medium is recirculated from an evaporator via a compressor, heat exchanger and a throttle to the evaporator. According to the invention, a condenser is arranged between the heat exchanger that absorbs the heat and the throttle, which is connected to the evaporator via the additional circuit of an auxiliary medium.
Nachfolgend werden anhand der Zeichnungen Aus¬ führungsbeispiele der Erfindung näher erläutert. Es zeigen:Exemplary embodiments of the invention are explained in more detail below with reference to the drawings. Show it:
Fig. 1 ein Prinzipschema einer ersten Ausführungsform der Erfindung undFig. 1 is a schematic diagram of a first embodiment of the invention and
BUREA U " Fig. 2 ein Prinzipschema einer weiteren Ausführungsform der Erfindung.BUREA U " Fig. 2 is a schematic diagram of another embodiment of the invention.
Ein Teil des Prinzipschemas gemäss Figur 1 ent¬ spricht demjenigen einer konventionellen Wärmepumpe. Ein Kompressor 1 saugt vom Verdampfer 2 kommendes, dampfförmi¬ ges Arbeitsmedium üblicher Art an und verdichtet diesen Dampf, wodurch er überhitzt wird. Beim Arbeitsmedium kann es sich z. B. um R 22 handeln. In einem Wärme¬ tauscher 3 wird dem Arbeitsmedium Wärme entzogen und dieses nach seiner Kondensation einem Vorratsbehälter 4 zugeführt. Von dort gelangt es über eine Drossel 5 zum Verdampfer 2 zurück.Part of the basic scheme according to FIG. 1 corresponds to that of a conventional heat pump. A compressor 1 draws in vaporous working medium of the usual type coming from the evaporator 2 and compresses this steam, as a result of which it is overheated. When working medium, it can be. B. R 22. In a heat exchanger 3, heat is extracted from the working medium and, after its condensation, it is fed to a storage container 4. From there it returns to the evaporator 2 via a throttle 5.
Dieser bekannte Kreislauf ist im Prinzipschema gemäss Figur 1 zum Teil gestrichelt eingezeichnet und entspricht einem Betriebszustand, bei welchem die Ventile 6 und 8 offen sind und die Ventile 7 und 9 geschlossen sind. Zur Aufrechterhaltung des bekannten Kreislaufes müsste zum Verdampfen des Mediums dem Verdampfer 2 von aussen Wärme zugeführt werden. Im Wärmetauscher 3 würde sodann die Ueberhitzungs- und Kondensationswärme des Medium durch den Heizkreis 10, in welchem die Zirkulationspumpe 11 an¬ geordnet ist, abgeführt.This known circuit is partly drawn in dashed lines in the basic scheme according to FIG. 1 and corresponds to an operating state in which the valves 6 and 8 are open and the valves 7 and 9 are closed. To maintain the known circuit, the evaporator 2 would have to be supplied with heat from the outside to evaporate the medium. In the heat exchanger 3 would then Overheating and condensation heat of the medium is dissipated by the heating circuit 10 in which the circulation pump 11 is arranged.
Gemäss der Erfindung ist nun zwischen dem Wärme¬ tauscher 3 und der Drossel 5 ein gesonderter Kondensator 12 geschaltet, wobei die direkte, gestrichelt gezeichnete Verbindung zwischen dem Wärmeaustauscher 3 einerseits und der Drossel 5 und dem Vorratsbehälter 4 andererseits wegfallen kann. Im Wärmetau¬ scher 3 erfolgt eine teilweise Kondensation des Arbeitsmediums. Im wesentlichen wird aber die Kondensation im. Kondensator 12 vorgenommen. Ein zur Kühlung dienendes Hilfsmedium, vorzugsweise Wasser, welches im Hilfskreislauf 13 zirkuliert, nimmt im Kondensa¬ tor 12 Wärme auf und gelangt über eine Pumpe 14 zum Ver¬ dampfer 2, wo es im Zuge der Verdampfung des Arbeitsmedi¬ ums die im Kondensator 12 aufgenommene Wärme abgibt und abgekühlt dem Kondensator 12 wieder zufliesst.According to the invention, a separate condenser 12 is now connected between the heat exchanger 3 and the throttle 5, it being possible for the direct, dashed line connection between the heat exchanger 3 on the one hand and the throttle 5 and the reservoir 4 on the other hand to be omitted. A partial condensation of the working medium takes place in the heat exchanger 3. Essentially, however, the condensation in the. Capacitor 12 made. An auxiliary medium for cooling, preferably water, which circulates in the auxiliary circuit 13, absorbs heat in the condenser 12 and reaches the evaporator 2 via a pump 14, where it is absorbed in the condenser 12 in the course of the evaporation of the working medium Releases heat and flows back to the condenser 12 when cooled.
Beim Anlaufen der Anlage mit tiefen Temperaturen (erstes Anlaufen) wird der Wärmetauscher 3 durch Oeffnen des Ventils 7 und Schliessen des Ventils 6 ausgeschaltet und das überhitzte Medium un¬ mittelbar dem Kondensator 12 zugeführt, um genügend Wärme für das Ver- dampfen des Arbeitsmediums bereitzustellen. Sobald die vorgesehenen Betriebstemperaturen erreicht sind, wird der Wärmeaustauscher 3 eingeschaltet, und die Anlage arbeitet nun in einem stationären Zustand. Die Ueberhitzüngswärme des vom Verdampfer kommenden Arbeitsmediums und ein Teil von dessen Kondensationswärme können nun als Nutzwärme dem Wärmeaustauscher 3 entnommen und durch den Heizkreislauf 12 einem Verbraucher zugeführt werden.When the system starts up at low temperatures (first start-up), the heat exchanger 3 is switched off by opening the valve 7 and closing the valve 6, and the superheated medium is fed directly to the condenser 12 in order to provide sufficient heat for the provide vaporization of the working medium. As soon as the intended operating temperatures have been reached, the heat exchanger 3 is switched on and the system now works in a stationary state. The superheat of the working medium coming from the evaporator and part of its heat of condensation can now be taken as useful heat from the heat exchanger 3 and supplied to a consumer by the heating circuit 12.
Der zusätzliche Kondensator 12 ermöglicht es, ideale Arbeitsbedingungen für die Durchführung des Ver¬ fahrens zu schaffen. Das Arbeitsmedium wird vor der Drossel 5 optimal abgekühlt, und die im Kondensator 12 gewonnene Kondensationswärme wird über den Hilfskreislauf 13 dem Verdampfer 2 zugeführt. Da zum Verdampfen keine oder nur teilweise Fremdwärme benötigt wird, kann das erfindungs- gemässe Verfahren universell angewendet werden.The additional capacitor 12 makes it possible to create ideal working conditions for carrying out the method. The working medium is optimally cooled in front of the throttle 5, and the heat of condensation obtained in the condenser 12 is fed to the evaporator 2 via the auxiliary circuit 13. Since no or only partial external heat is required for evaporation, the method according to the invention can be used universally.
Durch Anordnung eines Mischventils 15 in den Hilfskreislauf 13 kann die Einrichtung leistungsgerecht einreguliert werden. Mit dem Mischventil 15 wird der Hilfs- kreislauf 13 in Abhängigkeit der Kompressorleistung und der im Heizkreislauf 10 weggeführten Wärmemenge optimal einreguliert, so dass sowohl der Verdampfer 2 wie auch der Kondensator 12 in den vorgesehenen Temperaturbereichen arbeiten.By arranging a mixing valve 15 in the auxiliary circuit 13, the device can be regulated in accordance with the output. With the mixing valve 15, the auxiliary Circuit 13 optimally regulated depending on the compressor output and the amount of heat carried away in the heating circuit 10, so that both the evaporator 2 and the condenser 12 operate in the intended temperature ranges.
Das Verfahren eignet sich auch dazu, Verlust¬ wärme anderer Anlagen, vor allem von Kühlanlagen oder Kühlgeräten, zur Verdampfung des Arbeitsmediums heranzu¬ ziehen. Ein Prinzipschema einer Einrichtung, welche dieses bewerkstelligt, ist in der Figur 2 gezeigt. Zu diesem Zweck ist nach dem Kondensator 12, vor dem Ventil 9, eine Zweigleitung 16 vorgesehen, die über ein Ventil 17 zu einer zweiten Drossel 18 und zum Verdampfer des Kühlgerätes 19 und schliesslich zur Saugleitung 20 des Kompressors 1 führt. Wird neben dem Ventil 9 auch das Ventil 17 geöffnet, so erfolgt eine Verdampfung des Arbeitsmediums sowohl im Verdampfer 2 als auch im Verdampfer des Kühlgerätes, solan¬ ge die benötigte Verdampfungstemperatur des Kühlgerätes nicht überschritten wird. Es kann daher die Verdampfungs¬ leistung im Verdampfer 2 und somit die Kondensation des Arbeitsmediums im Kondensator 12 herabgesetzt werden.The method is also suitable for using heat loss from other systems, especially cooling systems or cooling devices, to evaporate the working medium. A basic diagram of a device which accomplishes this is shown in FIG. 2. For this purpose, a branch line 16 is provided after the condenser 12, upstream of the valve 9, which leads via a valve 17 to a second throttle 18 and to the evaporator of the cooling device 19 and finally to the suction line 20 of the compressor 1. If, in addition to the valve 9, the valve 17 is also opened, the working medium is evaporated both in the evaporator 2 and in the evaporator of the cooling device as long as the required evaporation temperature of the cooling device is not exceeded. The evaporation rate in the evaporator 2 and thus the condensation of the working medium in the condenser 12 can therefore be reduced.
BURE^ Der Kondensationsanteil im Wärmetauscher 3 ist somit grösser, so dass diesem eine erhöhte Wärmeleistung entnommen werden kann. Ist die Leistungsfähigkeit des Kühlgerätes 19 genügend gross, so kann gegebenenfalls das Ventil 9 ganz geschlossen und die Kondensation zur Gänze im Wärmetauscher 3 vorgenommen werden. So könnte z. B. durch das erfindungsgemässe Verfahren die Kondensations¬ wärme von Kühlgeräten und Kühlanlagen im Haushalt zur Aufbereitung von heissem Gebrauchswasser ausgenützt werden.BURE ^ The proportion of condensation in the heat exchanger 3 is thus greater, so that an increased heat output can be taken from it. If the performance of the cooling device 19 is sufficiently high, the valve 9 can optionally be completely closed and the condensation can be carried out entirely in the heat exchanger 3. For example, B. by the inventive method, the heat of condensation of cooling devices and cooling systems in the household can be used for the treatment of hot service water.
Bei einer weiteren Ausführungsform der Erfindung ist im Heizkreislauf 10 ein Injektor 23 angeordnet. Dieser hat eine ähnliche Regulierfunktion wie das Misch¬ ventil 15. Der Injektor 23 sorgt dafür, dass in Abhängig¬ keit der Temperatur des Mediumkreislaufes ein Teil des Heizkreislaufes direkt vom Vorlauf 21 in den Rücklauf 22 gelangt. Damit wird bei tiefen Temperaturen eine zu starke Abkühlung des Mediumkreislaufes verhindert. Bei höheren Temperaturen wird der Injektor wirkungslos. Der Injektor arbeitet automatisch in Abhängigkeit der Heizkreislauf-Temperatur und benötigt keine äussere Kraftanwendung zu dessen Betä¬ tigung. In a further embodiment of the invention, an injector 23 is arranged in the heating circuit 10. This has a similar regulating function to the mixing valve 15. The injector 23 ensures that, depending on the temperature of the medium circuit, part of the heating circuit passes directly from the flow 21 into the return 22. This prevents excessive cooling of the medium circuit at low temperatures. The injector becomes ineffective at higher temperatures. The injector works automatically depending on the heating circuit temperature and does not require any external force to operate it.
