Description

Einrichtung zur Erzeugung elektrischer Energie ^ o Device for generating electrical energy ^ o
Die Erfindung bezieht sich auf eine Einrichtung zur Erzeugung ω elektrischer Energie, mit einem Thermogenerator und einer damit 1^ ω koppelbaren Wärmequelle.The invention relates to a device for generating ω electrical energy, with a thermogenerator and thus a heat source 1 ω ω coupled.
Akkumulatoren haben sich als Energiequellen für mobile elektrische Geräte etabliert. Allerdings benötigt das Aufladen derselben einen Netzanschluss oder eine sonstige elektrische Energiequelle, welche nicht immer zur Verfügung steht. Es gibt deshalb z.B. brennerbasierte Thermogeneratoren, welche Akkus im Outdoorbereich nachladen können, oder elektronische Kleingeräte betreiben können. Dazu ist jedoch der Brennerbetrieb notwendig, was die Mobilität einschränkt.Accumulators have become established as energy sources for mobile electrical appliances. However, the charging of the same requires a power supply or other electrical energy source, which is not always available. There are therefore e.g. burner-based thermal generators, which can recharge batteries in the outdoor area, or operate small electronic devices. For this purpose, however, the burner operation is necessary, which limits the mobility.
Aufgabe der vorliegenden Erfindung ist es, eine Einrichtung der eingangs genannten Art zu schaffen, die als autarke, mobile Energiequelle einen Akkumulator ersetzen oder aufladen kann.Object of the present invention is to provide a device of the type mentioned, which can replace or recharge a rechargeable battery as a self-sufficient, mobile power source.
Zur Lösung dieser Aufgabe wird vorgeschlagen, dass als Wärmequelle zumindest eine Sorptions-Kältemaschine mit einem Verdampfer und einem Adsorber vorgesehen ist, dass der Verdampfer und/oder der Adsorber der Sorptions-Kältemaschine in thermischem Kontakt mit dem Thermogenerator stehen, dass der Thermogenerator zur Regeneration der Sorptions-Kältemaschine zumindest zum Heizen ausgebildet ist und/oder dass der Adsorber der Sorptions-Kältemaschine lösbar und austauschbar mit der übrigen Einrichtung verbunden ist.To solve this problem it is proposed that at least one sorption chiller with an evaporator and an adsorber is provided as a heat source, that the evaporator and / or the adsorber of the sorption refrigerator are in thermal contact with the thermogenerator, that the thermogenerator for the regeneration of Sorption chiller is designed at least for heating and / or that the adsorber of the sorption chiller is releasably and replaceably connected to the other device.

Infrastruktur von erhältlichen regenerierten Adsorberkammern für den Generatorbetrieb.Infrastructure of available regenerated adsorber chambers for generator operation.
Zweckmäßigerweise ist eine Verbindungsleitung mit einem verstellbaren Ventil zwischen dem Verdampfer und dem Adsorber der Sorptions-Kältemaschine vorgesehen.Conveniently, a connecting line with an adjustable valve between the evaporator and the adsorber of the sorption refrigerator is provided.
Nach Betätigung des Ventils bildet sich eine lang anhaltende Temperaturdifferenz zwischen dem Verdampfer und dem Adsorber, durch welche der Thermogenerator betrieben wird.After actuation of the valve, a long-lasting temperature difference between the evaporator and the adsorber, through which the thermogenerator is operated forms.
Vorteilhaft ist es, wenn der Thermogenerator zwischen dem Verdampfer und dem Adsorber angeordnet ist und mit beiden in thermischem Kontakt steht. In der Adsorptionsphase mit Verdampfung des Kältemittels wird der Adsorber heiß, während der Verdampfer abkühlt, so dass der dazwischen befindliche Thermogenerator von einer Seite mit Wärme und der anderen Seite mxt Kälte beaufschlagt wxrd und damit einen guten Wirkungsgrad erzielt .It is advantageous if the thermal generator is arranged between the evaporator and the adsorber and is in thermal contact with both. In the adsorption phase with evaporation of the refrigerant, the adsorber becomes hot while the evaporator cools, so that the intermediate thermal generator is heated from one side to the other side mxt cold wxrd and thus achieved a good efficiency.
Besonders vorteilhaft ist es, wenn der Thermogenerator J wenigstens ein Peltierelement aufweist. <It is particularly advantageous if the thermal generator J has at least one Peltier element. <
Damit ist in einem Bauteil sowohl der Thermogenerator als auch c ein Heiz- und Kühlelement gebildet, mit dem die Möglichkeit der Regeneration der Adsorberkammer besteht, wenn eine Stromversorgung für das Peltierelement zur Verfügung steht. Zur Regeneration der Sorptions-Kältemaschine wird die Adsorberkammer ausgeheizt und die Verdampferkammer wird bei der elektrischen Regeneration gekühlt, so dass die verdampfte Flüssigkeit in der Verdampferkammer wiederum kondensiert. Diese Regenerationsweise ermöglicht eine geschlossene, kompakte Bauform der Einrichtung.Thus, both the thermogenerator and c a heating and cooling element is formed in one component, with which there is the possibility of regeneration of the adsorber when a power supply for the Peltier element is available. For regeneration of the sorption chiller, the adsorber chamber is baked and the evaporator chamber is cooled during the electrical regeneration, so that the evaporated liquid condenses again in the evaporator chamber. This regeneration allows a closed, compact design of the device.
Gegebenenfalls kann ein Kältemittelbehälter und/oder ein Adsorber-Behälter vor Aktivierung der Sorptions-Kältemaschine unter Unterdruck stehen. Dadurch steht das Kältemittel nach dem Herstellen der Verbindung zwischen Verdampfer und Adsorber unter reduziertem Dampfdruck, so dass eine beschleunigte Reaktion erreicht wird.Optionally, a refrigerant container and / or an adsorber container may be under negative pressure before activation of the sorption refrigerator. As a result, after establishing the connection between the evaporator and the adsorber, the refrigerant is under reduced vapor pressure, so that an accelerated reaction is achieved.
Zusätzliche Ausgestaltungen der Erfindung sind m den weiteren Unteransprüchen aufgeführt. Nachstehend ist die Erfindung mit ihren wesentlichen Einzelheiten anhand der Zeichnung noch näher erläutert .Additional embodiments of the invention are listed m the further subclaims. The invention with its essential details with reference to the drawings is explained in more detail below.

The | Thermoelectric generator 3 is coupled to a heat source <is formed in the embodiment by a sorption chiller 13 c. This has an evaporator 12 and a t
Adsorber 5 auf.Adsorber 5 on.
Im Ausführungsbeispiel stehen sowohl der Verdampfer 12 als auch der Adsorber 5 in thermischem Kontakt mit dem Thermogenerator 3. Der Thermogenerator 3 ist zwischen einem Kältemittel- Behälter 2 des Verdampfers 12 und einem Adsorber-Behälter 4 angeordnet, wodurch sich günstiges thermische Verhältnisse und auch eine kompakte Bauform ergeben.In the exemplary embodiment, both the evaporator 12 and the adsorber 5 are in thermal contact with the thermogenerator 3. The thermogenerator 3 is disposed between a refrigerant tank 2 of the evaporator 12 and an adsorber vessel 4, resulting in favorable thermal conditions and also a compact Design result.
In dem Adsorber-Behälter 4 befindet sich ein Sorptionsmittel, vorzugsweise Zeolith. Außer Zeolith kommt als Sorptionsmittel unter anderem auch Aktivkohle oder Silikagel in Frage.In the adsorbent container 4 is a sorbent, preferably zeolite. Apart from zeolite, the sorbent used may also be activated carbon or silica gel.
Der Verdampfer 12 beinhaltet ein Kältemittel 6, beispielsweise Wasser wegen der meist vorhandenen Verfügbarkeit, das sich in dem Kältemittel-Behälter 2 befindet. Der Kältemittel-Behälter 2 und der Adsorber-Behälter 4 sind über eine Verbindungsleitung 7 , in deren Verlauf ein Ventil 8 vorgesehen ist, miteinander verbunden.The evaporator 12 includes a refrigerant 6, for example, water because of the most available availability, which is located in the refrigerant tank 2. The refrigerant container 2 and the adsorber container 4 are connected to each other via a connecting line 7, in the course of which a valve 8 is provided.
Durch Öffnen des Ventiles 8 wird eine Verbindung zwischen dem Adsorber 5 und dem Verdampfer 12 hergestellt. Dabei tritt eine radikale Absenkung des Wasserdampfdrucks in dem mit Wasser gefüllten Verdampfer 12 auf. Das Wasser beginnt zu sieden und kann schließlich zu Eis gefrieren. Die Wasserdampfdruckabsenkung erfolgt durch den Kontakt mit dem getrockneten Zeolith, dessen Adsorptionsfähigkeit für Wasser ausgenutzt wird. Das Zeolith heizt sich dabei auf vergleichsweise hohe Temperaturen auf. Das Ventil 8 ist vorzugsweise einstellbar, so dass damit die p Reaktionsgeschwindigkeit der Sorptions-Kältemaschine 13 c beeinflussbar ist. LBy opening the valve 8, a connection between the adsorber 5 and the evaporator 12 is established. In this case, a radical lowering of the water vapor pressure occurs in the water-filled evaporator 12. The water starts to boil and can eventually freeze to ice. The water vapor pressure reduction takes place by contact with the dried zeolite, whose adsorption capacity for water is exploited. The zeolite heats up to relatively high temperatures. The valve 8 is preferably adjustable, so that thus the p reaction rate of the sorption chiller 13 c can be influenced. L
Durch den thermischen Kontakt einerseits des Adsorbers 5 und d andererseits des Verdampfers 12 mit dem Thermogenerator 3 wird dieser an seinen Außenseiten mit unterschiedlichen Temperaturen beaufschlagt und setzt diese Temperaturdifferenz in Elektrizität um. Über elektrische Leitungen 9, 10 kann der Thermogenerator 3 direkt mit einem Verbraucher 11 und/oder mit einem Akkumulator zur Speicherung der elektrischen Energie verbunden sein.Due to the thermal contact on the one hand of the adsorber 5 and d on the other hand, the evaporator 12 with the thermogenerator 3, this is acted upon on its outer sides with different temperatures and converts this temperature difference into electricity. Via electrical lines 9, 10, the thermal generator 3 may be connected directly to a load 11 and / or to an accumulator for storing the electrical energy.
Bevorzugt werden als Thermogenerator ein oder mehrere Peltierelemente eingesetzt. Das Peltierelement kann zur Regeneration des Adsorbers 5 verwendet werden, indem einerseits ein Ausheizen des in dem Adsorber-Behälter 4 befindlichen Sorptionsmittels vorgenommen wird, während der Verdampfer 12 gekühlt wird, so dass die verdampfte Flüssigkeit in dem Kältemittel-Behälter 2 wiederum kondensiert.Preferably, one or more Peltier elements are used as thermogenerator. The Peltier element can be used to regenerate the adsorber 5 by, on the one hand, heating the adsorbent container 4 in the sorbent while the evaporator 12 is cooled so that the vaporized liquid in the refrigerant container 2 condenses again.
Bedarfsweise kann der Adsorber 5 der Sorptions-Kältemaschine lösbar mit der übrigen Einrichtung verbunden sein. Die Regeneration des Adsorbers 5 kann dadurch getrennt von der Einrichtung 100 vorgenommen werden und durch austauschbare Adsorber 5 kann ein praktisch durchgehender Betrieb des Adsorber-Generators 1 erfolgen. Der Kältemittel-Behälter 2 und/oder der Adsorber-Behälter 4 können unter Vakuum beziehungsweise Unterdruck stehen, so dass nach dem Öffnen des Ventils 8 eine beschleunigte Reaktion eintritt. Für besondere Anwendungen können als Wärmequelle für den Thermogenerator 3 sowohl eine Sorptions-Kältemaschine 13 als auch ein oder mehrere Latentwärmespeicher eingesetzt werden. Die als weitere Wärmequelle zusätzlich zu der Sorptions- £ Kältemaschine vorgesehenen Latentwärmespeicher sind mit einer c Salzlösung befüllt. Nach Auslösen einer Kristallisation der LIf necessary, the adsorber 5 of the sorption refrigerator can be releasably connected to the rest of the device. The regeneration of the adsorber 5 can be carried out separately from the device 100 and by exchangeable adsorber 5 can be carried out a virtually continuous operation of the adsorber generator 1. The refrigerant container 2 and / or the adsorber container 4 may be under vacuum or negative pressure, so that after the opening of the valve 8, an accelerated reaction occurs. For special applications, as a heat source for the thermal generator 3 both a sorption chiller 13 and one or more latent heat storage can be used. The latent heat storage devices provided as a further heat source in addition to the sorption refrigerator are filled with a c saline solution. After triggering a crystallization of the L
Salzlösung wird Kristallisationswärme frei, die zur Erwärmung d des Thermogenerators 3 zur Verfügung steht. Sind mehrere Latentwärmespeicher vorgesehen, die in thermischem Kontakt mit dem Thermogenerator 3 stehen, können diese entweder gleichzeitig aktiviert werden für eine hohe Wärmebeaufschlagung des Thermogenerators 3 oder aber zeitlich nacheinander für einen Betrieb über einen entsprechend längeren Zeitraum.Salt solution is free heat of crystallization, which is available for heating d of the thermogenerator 3 available. If several latent heat accumulators are provided which are in thermal contact with the thermogenerator 3, they can either be activated simultaneously for a high heat input of the thermogenerator 3 or chronologically in succession for operation over a correspondingly longer period of time.
Die erfindungsgemäße Einrichtung 100 eignet sich insbesondere als elektrisch und thermisch regenerierbarer Akku für Anwendungen im OutdoorBereich, im Bereich wearable Clothes, Mikroenergietechnik, tragbare Kleingeräte wie Mobiltelefon, Satellitentelefon, Radio, Funk, CD- , DVD- ,MP3Player , Energierückgewinnung im Kraftfahrzeug, waste-energy-recovery, also generell als Energiespeicher.The device 100 according to the invention is particularly suitable as an electrically and thermally regenerable rechargeable battery for outdoor applications, wearable clothes, micro-energy technology, portable small devices such as mobile phone, satellite phone, radio, radio, CD, DVD, MP3 player, energy recovery in the motor vehicle, waste energy-recovery, ie generally as energy storage.
