Abstract

The plant comprising a heat pump and used to collect the heat for heating from surrounding heat sources such as outdoor air, is provided with a water tank (5) which is in heat exchange relationship on one hand with the surrounding heat source and, on the other hand, with the coolant circuit of the heat pump through a coolant evaporator (6). By drawing heat from the water tank (5) and introducing that heat into the coolant circuit, the water tank (5) is always kept at a low temperature close to 0 C so that there is almost permanently a heat transfer from the surrounding heat sources towards the water tank (5). To reduce the size of the water tank (5), a coolant evaporator (7) is provided in contact with the outdoor air and it evaporates part of the coolant which is variable according to the outdoor temperature. During hot periods the outdoor evaporator (7) may be used to heat the water tank which is possibly frozen by introducing into the water tank (5) the heat coming from the outdoors air through an additional liquifier (9) mounted into the water tank (5).

Description

Vorrichtung zur Gewinnung von Heizwärme nach dem Wärmepumpenprinzip Device for the generation of heating energy according to the heat pump principle
Die Erfindung betrifft eine Vorrichtung zur Gewinnung von Heizwärme nach dem Wärmepumpenprinzip aus umgebenden Wärmequellen, wie Außenluft, Sonneneinstrahlung usw., Hausabwässern und aus der Abwärme eines Wärmepumpen-Antriebsverbrennungsmotors.The invention relates to a device for obtaining heat according to the heat pump principle from surrounding heat sources, such as outside air, solar radiation, etc., domestic waste water and from the waste heat of a heat pump drive internal combustion engine.
In den Deutschen Patentanmeldungen P 26 34 233.6-13 und P 27 15 075.0 sind Wärmepumpenanlagen zur Gewinnung von Heizwärme aus umgebenden Wärmequellen beschrieben, die mit einem Wasserspeicher arbeiten, der einerseits mit den umgebenden Wärmequellen und andererseits über einen Verdampfer mit dem Kältemittelkreislauf der Wärmepumpe in Wärmetausch steht. Durch den Entzug von Wärme aus dem Wasserspeicher in den Kältemittelkreislauf steht dieser Wasserspeicher ständig auf einem sehr niedrigen Temperaturniveau, im all-gemeinen 0ºC, so daß im Winter fast immer, außer in Frostperioden, ein Wärmetransport von den wärmeren Wärmequellen in den Wasserspeicher möglich ist. Da die über den Kältemittelkreislauf in einen Heizungskreislauf überführte Wärmemenge im wesentlichen ausschließlich dem Wasserspeicher entzogen wird, ist bereits zur Beheizung eines Einfamilienhauses ein relativ großer Wasserspeicher erforderlich.The German patent applications P 26 34 233.6-13 and P 27 15 075.0 describe heat pump systems for the generation of heat from surrounding heat sources, which work with a water storage tank which on the one hand works with the surrounding heat sources and on the other hand uses an evaporator to exchange heat with the refrigerant circuit of the heat pump stands. Due to the removal of heat from the water reservoir into the refrigerant circuit, this water reservoir is constantly at a very low temperature level, in general 0ºC, so that in winter almost always, except in Frost periods, a heat transfer from the warmer heat sources into the water reservoir is possible. Since the amount of heat transferred via the refrigerant circuit into a heating circuit is extracted essentially exclusively from the water reservoir, a relatively large water reservoir is required for heating a family home.
Eine Verkleinerung des Wasserspeichers ist möglich, wenn nach der Lehre von "Öl + Gasfeuerung 12/ 1976" Seite 676 als Wärmepumpenantrieb ein Diesel-Motor eingesetzt wird, dessen Abgaswärme und Kühlwasserwärme zumindest teilweise in den Heizungskreislauf überführt werden,welche Wärmemengen durch die Wärmepumpe nicht mehr aufgebracht zu werden brauchen.A reduction in the size of the water reservoir is possible if, according to the teaching of "Oil + gas combustion 12/1976" page 676, a diesel engine is used as the heat pump drive, the exhaust gas heat and cooling water heat of which are at least partially transferred to the heating circuit, and the amount of heat no longer produced by the heat pump need to be applied.
Die Wärmepumpenanlage nach der US-PS 3 563 304 ver- wendet zwei Kältemittelverdampfer, von denen der erste mit der umgebenden Luft und der zweite mit einem Wasserspeich in Wärmetausch steht. Über den ersten Verdampfer erfolgt die Hauptwärmezufuhr, solange die Umgebungstemperaturen wesentlich über 0°C liegen. Bei geringeren Außentemperaturen, insbesondere während Frostperioden, wird dem Wasserspeicher unter Eisbildung die benötigte Wärme durch den zweiten Verdampfer entzogen. Das Zurückschmelzen des Eises erfolgt zu Zeiten billigen Nachtstroms durch elektrische Widerstandsheizung. Nachteilig ist der dennoch relativ hohe Stromverbrauch durch die elektrische Widerstandsheizung, die sehr häufig eingeschaltet werden muß, da bereits bei Außentemperaturen von etwa 5 - 8°C der Außenluft-Verdampfer aufgrund Vereisung nicht mehr die zur Beheizung erforderliche Wärmemenge heranschaffen kann. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Gewinnung von Heizwärme nach dem Wärmepumpenprinzip aus umgebenden Wärmequellen zu schaffen, die mit einem relativ kleinen Wasserspeicher auskommt. Die zu schaffende Vorrichtung soll zudem ohne elektrische Zusatzheizung auskommen und umweltfreundlich arbeiten.The heat pump system according to US Pat. No. 3,563,304 uses two refrigerant evaporators, the first of which is in heat exchange with the surrounding air and the second with a water reservoir. The main heat is supplied via the first evaporator as long as the ambient temperature is significantly above 0 ° C. At lower outside temperatures, especially during frosty periods, the heat required is extracted from the water reservoir by ice formation by the second evaporator. The ice melts back at times of cheap night-time electricity using electrical resistance heating. A disadvantage is the relatively high power consumption due to the electrical resistance heating, which has to be switched on very frequently, since even at outside temperatures of around 5 - 8 ° C the outside air evaporator can no longer bring in the amount of heat required for heating due to icing. The invention has for its object to provide a device for obtaining heat according to the heat pump principle from surrounding heat sources, which manages with a relatively small water storage. The device to be created should also do without additional electrical heating and work in an environmentally friendly manner.
Diese Aufgabe wird mit einer Vorrichtung der eingangs genannten Art gelöst, die erfindungsgemäß gekennzeichnet ist durch einen Kältemittelkreislauf mit einem ersten, mit der Außenluft in Wärmetausch stehenden Verdampfer und mit einem nachgeordneten zweiten, mit einem Wasserspeicher in Wärmetausch stehenden Verdampfer, welcher Wasserspeicher seinerseits mit Wärmequellen, wie Sonneneinstrahlung, Hausabwässer, in Wärmetausch steht sowie einen Kältemittelverflüssiger enthält , der bei warmer Witterung vorübergehend in den Kältemittelkreislauf einschaltbar ist.This object is achieved with a device of the type mentioned at the outset, which is characterized according to the invention by a refrigerant circuit with a first evaporator which is in heat exchange with the outside air and with a downstream second evaporator which is in heat exchange with a water store, which water store in turn with heat sources, such as solar radiation, house wastewater, is in heat exchange and contains a refrigerant condenser that can be switched on temporarily in the refrigerant circuit in warm weather.
Der die Außenluftwärme nutzende erste Verdampfer ist im Kältemittelkreislauf unmittelbar hinter dem Expansionsventil angeordnet. Bei kaltem Wetter und/oder weitgehender Windstille wird darin weniger Kältemittel verdampfen als bei warmer und/oder stark windiger Witterung. Der nach Durchlaufen des Außenluft-Verdampfers noch flüssige Teil des Kältemittels wird beim anschließenden Durchgang durch die im Wasser- bzw. Latentwärmespeicher befindliche Kältemittelleitung verdampft. Durch dieses sich selbst regulierendeThe first evaporator, which uses the outside air heat, is arranged in the refrigerant circuit immediately behind the expansion valve. In cold weather and / or largely no wind, less refrigerant will evaporate in it than in warm and / or very windy weather. The part of the refrigerant which is still liquid after passing through the outside air evaporator is evaporated during the subsequent passage through the refrigerant line located in the water or latent heat store. Through this self-regulating
Zusammenwirken beider Verdampfer wird die nach der jeweiligen Witterung gerade verfügbare Außenluftwärme zur Kältemittelverdampfung genutzt. Reicht diese dafür nicht vollständig aus, wird die jeweilige Restflüssigkeit durch Energieentnahme aus dem Latentspeicher verdampft. Die Größe des Außenluft-Verdampfers und des Latentwärmespeichers sind in einer wirtschaftlich optimalen Weise aufeinander abzustimmen, wobei zu berücksichtigen ist, daß nicht immer Platz für das Aufstellen eines größeren Speicherbeckens vorhanden ist. Ferner ist in solche Betrachtungen miteinzubeziehen, daß es doch einmal lange kalt sein kann und dann nach Vereisung des Speicherbeckens nicht mehr genügend Verdampfungswärme entzogen werden kann. Dieses Problem kann man, ohne den Außenluft-Verdampfer überdimensionieren zu müssen, dadurch lösen, daß dem Außenluft-Verdampfer ein oder mehrere Gebläse zugeordnet werden, die unter der Kontrolle eines Außenluft-Temperaturfühlers und evtl. eines Windmessers stehen. Dieser Außenluft-Temperaturfühler setzt das bzw. die Gebläse erst ab Unterschreitung einer einstellbaren Außenlufttemperatur, z.B. -10°C, in Betrieb, um für eine durch das Gebläse bestimmbare Mindestluft— geschwindigkeit zu sorgen. Damit läßt sich für diese Zeiten der Spitzenbelastung Außenluft-Verdampferfläche sparen, die in wärmeren Zeiten nicht benötigt wird. Auch der Latent-wärmespeicher kann kleiner gehalten werden.When the two evaporators work together, the outside air heat that is available after the respective weather is used to evaporate the refrigerant. If this is not sufficient for this, the respective residual liquid is evaporated by taking energy from the latent storage. The size of the outside air evaporator and the latent heat store are to be coordinated with one another in an economically optimal manner, taking into account that there is not always space for the installation of a larger storage tank. It should also be taken into account in such considerations that it can be cold for a long time and then after the storage basin has iced up, it is no longer possible to extract enough heat of vaporization. This problem can be solved without having to oversize the outside air evaporator by assigning one or more blowers to the outside air evaporator, which are under the control of an outside air temperature sensor and possibly an anemometer. This outside air temperature sensor only starts the blower (s) below an adjustable outside air temperature, eg -10 ° C, in order to ensure a minimum air speed that can be determined by the blower. This means that outside air evaporator surface can be saved for these times of peak load, which is not required in warmer times. The latent heat storage can also be kept smaller.
Das zuschaltbare Gebläse kann für eine bestimmte konstante Mindestluftgeschwindigkeit ausgelegt sein oder aber einen unter der Kontrolle des Außenluft-Temperaturfühlers stehenden Drehzahlregler aufweisen, um die Gebläsedrehzahl mit fallender Außenlufttemperatur zu steigern.The switchable blower can be designed for a certain constant minimum air speed or can have a speed controller under the control of the outside air temperature sensor in order to increase the blower speed with falling outside air temperature.
Wie ausgeführt, wird während ungünstiger Witterungsbedingungen der Wärmevorrat des Latentwärmespeichers, notfalls bis hin zur teilweisen Vereisung des Wasserinhalts, herangezogen. Umgekehrt kann der Außenluft-Verdampfer in Perioden warmen Wetters, z.B. ab einer Außentemperatur von + 10ºC, zur Regenierierung des Energievorrats im Latentwärmespeicher genutzt werden. Bei derart warmem Wetter reichen Motorabwärme und die Wärme der Auspuffgase für die Beheizung des Hauses aus. Der Wärmepumpenprozeß wird dann mittels temperaturgesteuerter automatischer Umschaltung benutzt, um mit hohem Wirkungsgrad Außenluftwärme über einen zusätzlichen, im Latentwärmespeicher befindlichen Verflüssiger in den Latentwärmespeicher zu bringen.As stated, the heat supply of the latent heat storage is used during unfavorable weather conditions, if necessary up to the partial icing of the water content. Conversely, the outside air evaporator can be used in periods of warm weather, for example from an outside temperature of + 10ºC can be used to regenerate the energy supply in the latent heat storage. In such warm weather, engine waste heat and the heat of the exhaust gases are sufficient to heat the house. The heat pump process is then used by means of temperature-controlled automatic switching in order to bring outside air heat into the latent heat store with high efficiency via an additional condenser located in the latent heat store.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand beigefügter Zeichnung näher beschrieben, die schematisch eine erfindungsgemäße Vorrichtung zur Gewinnung von Heizwärme zeigt.An embodiment of the invention is described below with reference to the accompanying drawing, which schematically shows a device according to the invention for the production of heating.
Der Kältemittelkreislauf der Vorrichtung zur Gewinnung von Heizwärme setzt sich, wie z.B. in den Patentanmeldungen P 26 34 233.6-13 und P 27 15 075.0 beschrieben, aus einem Kompressor 1, einem mit dem Heizungskreislauf 2 in Wärmetausch stehenden Kondensator 3, einem Entspannungsventil 4 und aus einem in einen Wasserspeicher 5 eingetauchten Kältemittelverdampfer 6 zusammen. Dem in den Wasserspeicher ein— getauchten Kältemittelverdampfer 6 ist jedoch ein Außenluft- Verdampfer 7 vorgeschaltet, der je nach Außenwitterung einen mehr oder minder großen Teil des Kältemittels verdampft und damit den Wasserspeicher 5 entlastet. Der Außenluft-Verdampfer 7 hat die weitere Aufgabe, bei verhältnismäßig warmerWitterung zur Regenerierung des Wasserspeichers Außenluftwärme verstärkt in den Wasserspeicher zu überführen. Hierzu ist in den Kältemittelkreislauf unmittelbar nach dem Kompressor 1 ein Zwei-Wege-Magnetventil 8 eingeschaltet, das bei entsprechend warmer Witterung den aus dem Kompressor kommenden Kältemitteldampf nicht in den Kondensator 3 des Heizungkreislaufs 2 leitet, sondern in den in den Wasserspeicher eingetauchten Verflüssiger oder Kondensator 9. Die durch den Außenluftverdampfer 7 aufgenommene Außenluftwärme und die in Wärme verwandelte Verdichtungsarbeit des Kompressors dient dann ausschließlich der Erwärmung des Wasserspeichers , während die Aufheizung des Heizkreislaufs 2 durch die Abwärme des zum Antrieb des Kompressors 1 vorgesehenen Dieselmotors 10 erfolgt. Hierzu stehen einerseits der Kühlwasserkreis lauf 11 und andererseits die Auspuffleitung 12 des Die -selmotors im Tausch mit parallel geschalteten Zweigen der Rücklaufleitung des Heizungskreislaufs 2.The refrigerant circuit of the device for the production of heating heat, as described for example in the patent applications P 26 34 233.6-13 and P 27 15 075.0, consists of a compressor 1, a condenser 3 which is in heat exchange with the heating circuit 2, an expansion valve 4 and a refrigerant evaporator 6 immersed in a water reservoir 5. However, the refrigerant evaporator 6 immersed in the water reservoir is preceded by an outside air evaporator 7 which, depending on the external weather, evaporates a more or less large part of the refrigerant and thus relieves the water reservoir 5. The outside air evaporator 7 has the further task of increasingly transferring outside air heat into the water storage device in relatively warm weather to regenerate the water storage device. For this purpose, a two-way solenoid valve 8 is switched on in the refrigerant circuit immediately after the compressor 1, which in suitably warm weather does not direct the refrigerant vapor coming from the compressor into the condenser 3 of the heating circuit 2, but into the condenser or condenser immersed in the water reservoir 9. The outside air heat absorbed by the outside air evaporator 7 and the compression work of the compressor converted into heat then serves exclusively to heat the water reservoir, while the heating circuit 2 is heated by the waste heat of the provided for driving the compressor 1 diesel engine 10. For this purpose, on the one hand, the cooling water circuit 11 and, on the other hand, the exhaust line 12 of the diesel engine are exchanged with branches of the return line of the heating circuit 2 connected in parallel.
