Description
Die Erfindung betrifft eine Vorrichtung zur Warmwasserbereitung durch Abwasserwärmerückgewinnung mittels einer einen Kompressor sowie einen Verdampfer aufweisenden Wärmepumpe, insbesondere mittels einer Klein-Wärmepumpe für Haushaltsanwendungen, mit einem Warmwasserspeicher, der durch den Verdampfer der Wärmepumpe mit Wärmeenergie gespeist wird.The invention relates to a device for hot water by wastewater heat recovery by means of a compressor and an evaporator having heat pump, in particular by means of a small heat pump for household applications, with a hot water tank, which is fed by the evaporator of the heat pump with heat energy.
Die Rückgewinnung von Abwasserwärme wird bei aus der Praxis bekannten Vorrichtungen meist durch Nassdampfkreisprozesse realisiert. Der hierbei eingesetzte Kompressor erwärmt sich im Betrieb in der Regel auf Temperaturen im Bereich zwischen etwa 70°C und 90°C, die somit meist erheblich höher sind als die bei maximal 60 Grad liegende Temperatur des Warmwasserspeichers. Aufgrund dieser erhöhten Temperatur gibt der Kompressor nennenswerte Wärme an die Umgebung ab, die ohne Weiteres mehr als 50 Watt betragen kann. Diese Kompressorwärme geht somit verloren, so dass die Klein Wärmepumpe keine ausreichend hohe Effizienz für einen wirtschaftlichen Betrieb erreicht.The recovery of waste heat is usually realized in known from the practice devices by wet steam cycle. The compressor used in this heats up during operation usually to temperatures in the range between about 70 ° C and 90 ° C, which are thus usually much higher than the maximum of 60 degrees lying temperature of the hot water tank. Due to this elevated temperature, the compressor releases significant heat to the environment, which can easily be more than 50 watts. This compressor heat is thus lost, so that the small heat pump does not achieve sufficiently high efficiency for economical operation.
Aus der
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Abwärme des Kompressors auf eine einfache und wirtschaftliche Weise zu nutzen, um somit eine effizientere Arbeitsweise bei der Abwasserwärmerückgewinnung zu erreichen.On this basis, the present invention seeks to use the waste heat of the compressor in a simple and economical way, thus achieving a more efficient operation in wastewater heat recovery.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Warmwasserspeicher mit dem Kompressor der Wärmepumpe über wenigstens eine Heatpipe in thermischer Verbindung steht, wobei der Warmwasserspeicher oberhalb des Kompressors angeordnet ist.This object is achieved according to the invention in that the hot water tank is in thermal communication with the compressor of the heat pump via at least one heat pipe, wherein the hot water tank is arranged above the compressor.
Der hierdurch erreichte Vorteil besteht im Wesentlichen darin, dass diese Heatpipes oder auch Wärmerohre bei geeigneter Anordnung und Ausführung große Wärmemengen transportieren können, soweit sich die Wärmequelle, hier also der Kompressor, am tieferen Ende der Heatpipe und die Wärmesenke, hier also der Warmwasserspeicher, am höheren Ende befindet. Diese Heatpipes sind üblicherweise mit einer leicht verdampfenden Flüssigkeit gefüllt, welche sich im Bereich des unteren Endes sammelt. Wird dieser Bereich erwärmt, so verdampft die Flüssigkeit und der Dampf verteilt sich im gesamten Rohr; im kälteren oberen Bereich kondensiert der Dampf und das Kondensat läuft aufgrund des Gefälles wieder nach unten. Durch Verdampfen und Kondensieren werden – ohne äußeren Antrieb – große Wärmeströme transportiert.The advantage achieved thereby consists essentially in the fact that these heat pipes or heat pipes can transport large amounts of heat with a suitable arrangement and design, as far as the heat source, here the compressor, at the lower end of the heat pipe and the heat sink, here the hot water tank on higher end. These heatpipes are usually filled with a slightly evaporating liquid, which collects in the region of the lower end. If this area is heated, the liquid evaporates and the steam is distributed throughout the pipe; in the colder upper area condenses the steam and the condensate runs down again due to the gradient. By evaporation and condensation - without external drive - large heat flows are transported.
Wird dagegen das obere Ende erwärmt, so kann ein Wärmetransport nur aufgrund der Wärmeleitung in der dünnen Rohrwand erfolgen; da die Flüssigkeit sich unten befindet, findet keine Verdampfung und somit auch keine Kondensation statt. Damit ist der Wärmestrom vom oberen zum unteren Ende erheblich kleiner, so dass in der Folge bei ausgeschaltetem Kompressor die Wärme im Warmwasserspeicher verbleibt.If, on the other hand, the upper end is heated, then heat transfer can only take place due to the heat conduction in the thin tube wall; since the liquid is at the bottom, there is no evaporation and thus no condensation. Thus, the heat flow from the upper to the lower end is considerably smaller, so that in the sequence when the compressor is switched off, the heat remains in the hot water tank.
Um einen möglichst optimalen Wirkungsgrad zu erreichen, schlägt die Erfindung weiter vor, dass die Heatpipe im guten Wärmekontakt mittels einer einseitig oder beidseitig unlösbaren Verbindung durch Verkleben, Schweißen oder Löten mit dem Warmwasserspeicher bzw. dem Kompressor verbunden ist.In order to achieve the best possible efficiency, the invention further proposes that the heat pipe is connected in good thermal contact by means of a unilaterally or bilaterally unsolvable connection by gluing, welding or soldering to the hot water tank or the compressor.
Es ist im Rahmen der Erfindung jedoch ebenso möglich, dass die Heatpipe in gutem Wärmekontakt mittels einer einseitig oder beidseitig lösbaren Verbindung über fest am Warmwasserspeicher bzw. dem Kompressor angeschlossene Klemmstücke oder vergleichbare Anschlussmittel verbunden ist. Diese Lösung erlaubt flexiblere Aufbaumöglichkeiten der Vorrichtung; insbesondere ist auch eine leichtere Demontage zu Zwecken der Wartung möglich.However, it is within the scope of the invention also possible that the heat pipe is connected in good thermal contact by means of a unilaterally or bilaterally releasable connection via fixed to the hot water tank or the compressor connected clamping pieces or similar connection means. This solution allows more flexible design options of the device; In particular, an easier disassembly for the purpose of maintenance is possible.
Weiter ist es von Vorteil, wenn die Heatpipes aus zumindest bereichsweise elastisch ausgebildeten Rohren bestehen. Dies erlaubt zunächst eine weitgehend freie Wahl der Positionen von Warmwasserspeicher und Kompressor, wobei lediglich vorausgesetzt wird, dass der Kompressor tiefer angeordnet ist als der Warmwasserspeicher. Durch die elastische Ausbildung der Rohre der Heatpipes können die im Betrieb auftretenden Vibrationen des Kompressors leichter abgefangen werden, so dass diese nicht auf den Speicher übertragen werden. Dies ermöglicht insgesamt einen leiseren Betrieb der Vorrichtung.Further, it is advantageous if the heat pipes consist of at least partially elastically formed tubes. This initially allows a largely free choice of positions of hot water tank and compressor, only assuming that the compressor is located lower than the hot water tank. Due to the elastic design of the pipes of the heat pipes, the vibrations occurring during operation of the compressor can be absorbed more easily, so that they are not transmitted to the memory. This allows for a total quieter operation of the device.
Um des Weiteren Wärmeverluste an die Umgebung zu vermeiden, empfiehlt es sich, dass der Kompressor, die Heatpipes sowie der Warmwasserspeicher von einer gemeinsamen Isolierung umschlossen sind. To further avoid heat loss to the environment, it is recommended that the compressor, the heat pipes and the hot water tank are surrounded by a common insulation.
Hierbei ist es insbesondere weiter vorteilhaft, dass die Isolierung mit einer Infrarotstrahlung reflektierenden Beschichtung versehen ist, so dass keine Strahlungswärme durch die Isolierung verloren gehen kann.In this case, it is also particularly advantageous that the insulation is provided with a coating reflecting infrared radiation, so that no radiant heat can be lost through the insulation.
Als Material für die Beschichtung bietet sich insbesondere Aluminium an.As a material for the coating is particularly suitable for aluminum.
Um darüber hinaus bereits eine Abstrahlung der im Kompressor entstehenden Wärme gering zu halten, empfiehlt es sich weiter, dass der Kompressor eine metallisch glänzende, strahlungsarme Oberfläche aufweist. Diese Oberfläche besteht zweckmäßigerweise aus korrosionsbeständigem Material wie Aluminium oder Chrom.In order to keep even a radiation of heat generated in the compressor low, it is further recommended that the compressor has a shiny metallic, low-radiation surface. This surface is expediently made of corrosion-resistant material such as aluminum or chromium.
Im Folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; die einzige Figur zeigt eine Vorrichtung nach der Erfindung in schematischer Darstellung.In the following the invention will be explained in more detail in an embodiment shown in the drawing; the single figure shows a device according to the invention in a schematic representation.
Die in der Zeichnung nur schematisch wiedergegebene Vorrichtung dient zur Warmwasserbereitung, wobei mittels einer Wärmepumpe eine Wärmerückgewinnung aus dem vorzugsweise bei Haushaltsanwendungen entstehenden Abwasser erfolgt. Diese Wärmepumpe besteht in üblicher Weise aus einem Kompressor
Weiter ist ein Warmwasserspeicher
Der Warmwasserspeicher
Diese Art der Wärmeübertragung sorgt dafür, dass ein Wärmetransport im Wesentlichen von unten nach oben erfolgt, da sich im oberen Bereich keine Flüssigkeit befindet, die verdampfen könnte. Ein Wärmetransport von oben nach unten findet daher nur über Wärmeleitung durch das Wärmerohr statt. Dieser Anteil ist jedoch vergleichsweise sehr gering. Dies führt im Ergebnis dazu, dass der im Betrieb sich über der Temperatur des Warmwasserspeichers
Um eine optimale Wärmeübertragung zu erreichen, stehen die beiden Heatpipes
Die Heatpipes
In ebenfalls nicht näher dargestellter Weise werden der Kompressor
Um auch die Strahlungswärme innerhalb der Isolierung abzuschirmen, kann diese Isolierung mit einer Infrarotstrahlung reflektierenden Beschichtung versehen sein. Für diese Beschichtung bietet sich insbesondere Aluminium an.In order to shield also the radiant heat within the insulation, this insulation can be provided with an infrared radiation reflecting coating. Aluminum is particularly suitable for this coating.
