Es ist allgemein bekannt, daß bestimmte mikroporöse Festkörper wie Zeolithe, Aktivkohle u. a., Stoffe unter Abgabe von Wärme energie adsorbieren und bei Aufnahme von Wärmeenergie desorbie ren können, wodurch die Möglichkeit der Energiespeicherung über größere Zeiträume gegeben ist. Ähnliche Prozesse laufen auch bei der Absorption und der Chemisorption sowie physikalischen Zu standsänderungen (z. B. Eis-Wasser-Dampf) ab. Zur Verringerung der unerwünschten Wärmeabgabe während des Desorptionsprozesses, d. h. der Wärmeaufnahme, sind die bekannten Wärmeenergie-Aufneh mer und -speicher möglichst optimal wärmeisoliert aufgebaut, wo bei das Einbringen in Vakuum besonders effizient ist.It is well known that certain microporous solids such as zeolites, activated carbon u. a., fabrics releasing heat adsorb energy and desorbie when absorbing thermal energy ren, which means the possibility of energy storage over longer periods are given. Similar processes are also running absorption and chemisorption as well as physical properties changes (e.g. ice-water-steam). To reduce unwanted heat emission during the desorption process, d. H. the heat absorption, are the known heat energy absorption mer and storage optimally insulated where possible when inserting in a vacuum is particularly efficient.
Problematisch ist jedoch der Adsorptions- (bzw. Absorptions- oder Chemisorptions-)vorgang, wenn die entstehende Wärmemenge entweder nicht benötigt (Kältetechnik) oder nicht im entstehen den Umfang benötigt (Sommer) wird.However, the problem of adsorption (or absorption) or chemisorption) process when the amount of heat generated either not required (refrigeration technology) or not being created the scope is needed (summer).
Der Stand der Technik ist gekennzeichnet durch eine Reihe von Veröffentlichungen zur Speicherung von Sonnenenergie unter Ver wendung von Zeolithen und anderen mikroporösen Festkörpern (vgl. DE-OS-27 20 561 oder DE-OS-35 12 805). In einigen Firmenschriften (vgl. Dornier-Prinz Solartechnik "Sonnenenergie optimal nutzen mit dem Vakuum-Röhren-Kollektor LUX 2000", Klöckner Wärmetechnik "Klöckner Solar-Heizsystem Astron" oder THERMOSOLAR Energie technik "Vakuum-Flachkollektor HVL") werden die Eigenschaften ausführlich dargestellt. Darüber hinaus liegt umfangreiche wis senschaftliche Literatur vor, wie z. B. Passos u. a.: "Simulation of an Intermittent Adsorptive Solar Cooling System", Solar Ener gy, 42(2), 103 (1989) oder Kose: "Solaranlage, Beispiel mit Schichtenladung", Sonnenenergie, 17(2), 44 (1992). Allen Syste men gemeinsam liegt das Bemühen um eine möglichst optimierte Wärmeaufnahme durch Vermeidung von Wärmeleitungs- und Strah lungsverlusten.The prior art is characterized by a number of Publications on storing solar energy under Ver use of zeolites and other microporous solids (cf. DE-OS-27 20 561 or DE-OS-35 12 805). In some company publications (see Dornier-Prinz Solartechnik "Optimal use of solar energy with the vacuum tube collector LUX 2000 ", Klöckner Wärmetechnik "Klöckner Solar Heating System Astron" or THERMOSOLAR Energie technology "vacuum flat collector HVL") are the properties detailed. In addition, there is extensive wis scientific literature, such as. B. Passos u. a .: "Simulation of an Intermittent Adsorptive Solar Cooling System ", Solar Ener gy, 42 (2), 103 (1989) or Kose: "Solar system, example with Stratified Charge ", Solar Energy, 17 (2), 44 (1992). Allen Syste What they all have in common is the effort to optimize them Heat absorption by avoiding heat conduction and radiation losses.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Aufnahme und Abgabe von Wärmeenergie zur Verfügung zu stellen, die alternierend eine Adsorptions- und Desorptionsphase eines fluiden Mediums an einem Speichermedium ermöglicht und eine weitestgehend effektive Wärmeenergieabgabe anstrebt.The invention has for its object a device for To provide absorption and dissipation of thermal energy, which alternate between an adsorption and desorption phase allows fluid medium on a storage medium and a strives for the most effective heat energy release.
Erfindungsgemäß besteht die Vorrichtung zur Aufnahme und Abgabe von Wärmeenergie aus einem vakuumdichten Gefäß 3 mit Ein- und Auslaßventilen 8; 9; 10; 14 und mit einer Kühlvorrichtung 13 an der Gefäßwand, in dem ein vakuumdichter Behälter 1 angeordnet ist, der eine oder mehrere Flächen 4; 12 zur Wärmeaufnahme und/ oder Wärmeabgabe besitzt und seinerseits ein Medium 2 zur Wärme speicherung enthält.According to the invention, the device for receiving and delivering thermal energy consists of a vacuum-tight vessel 3 with inlet and outlet valves 8 ; 9 ; 10 ; 14 and with a cooling device 13 on the vessel wall, in which a vacuum-tight container 1 is arranged, which has one or more surfaces 4 ; 12 for heat absorption and / or heat emission and in turn contains a medium 2 for heat storage.
Als Medium zur Wärmespeicherung werden vorzugsweise mikroporöse Festkörper, insbesondere Zeolithe, eingesetzt, wobei jedoch auch andere bekannte, geeignete Medien verwendet werden können.Microporous are preferably used as heat storage medium Solids, in particular zeolites, are used, but also other known, suitable media can be used.
Zur Steuerung der Vorrichtung kann eine photovoltaische Zelle 7 verwendet werden, die beispielsweise, wenn sie aus Material mit hoher thermischer Belastbarkeit wie Galliumarsenid gefertigt ist, als Bestandteil der Fläche 4 des Behälters 1 ausgebildet werden kann.To control the device, a photovoltaic cell 7 can be used which, for example, if it is made of material with high thermal load capacity, such as gallium arsenide, can be formed as a component of the surface 4 of the container 1 .
Die erfindungsgemäße Vorrichtung ist vorzugsweise zur Nutzung von Sonnenenergie vorgesehen. Zu diesem Zweck weist das vakuum dichte Gefäß 3 ein Fenster 5 auf, durch das das Sonnenlicht hindurchtreten kann und dem Behälter 1 auf diese Weise die Energieaufnahme ermöglicht wird. Dieses Fenster 5 kann wellen längen-selektiv beschichtet sein.The device according to the invention is preferably provided for the use of solar energy. For this purpose, the vacuum-tight vessel 3 has a window 5 through which the sunlight can pass and in this way the container 1 is able to absorb energy. This window 5 can be coated in a wavelength-selective manner.
Wie bereits erwähnt, erfolgen Wärmeaufnahme und -abgabe alter nierend durch eine Adsorptions- und Desorptionsphase eines flui den Mediums an einem Speichermedium, vorzugsweise einem mikropo rösen Festkörper. In der Desorptionsphase wird der erfindungsge mäßen Vorrichtung Wärmeenergie, z. B. in Form von Sonnenenergie, zugeführt. Das umgebende Vakuum verhindert dabei im Zusammenhang mit einer an sich bekannten Beschichtung reflektierender Ober flächen die Ableitung von Wärmeenergie an die Umgebung über das Gefäß 3. Die Erzeugung des Vakuums erfolgt dabei, zeitlich an die Desorptionsphase gekoppelt, mit Hilfe einer Vakuumpumpe 6 geringer Leistung, die ihre elektrische Energie z. B. aus der in das Gehäuse integrierten photovoltaischen Zelle 7 bezieht. Über Ventile 8; 9; 10; 14 und Vorrichtungen zur Wärmeableitung 12; 13 ist eine Veränderung des Vakuums möglich.As already mentioned, heat absorption and dissipation take place alternately through an adsorption and desorption phase of a fluid medium on a storage medium, preferably a microporous solid. In the desorption phase, the device according to the invention is thermal energy, for. B. in the form of solar energy. The surrounding vacuum prevents the dissipation of thermal energy to the surroundings via the vessel 3 in connection with a known reflecting upper surface. The vacuum is generated, temporally coupled to the desorption phase, with the help of a vacuum pump 6 of low power, which z. B. from the integrated in the housing photovoltaic cell 7 . Via valves 8 ; 9 ; 10 ; 14 and heat dissipation devices 12 ; 13 a change in the vacuum is possible.
Der erfindungsgemäßen Vorrichtung liegt weiterhin die folgende Funktionsweise zugrunde:The device according to the invention is also the following How it works:
Während der Adsorptionsphase und demzufolge Unterbrechung der äußeren Energiezufuhr wird eine möglichst effektive Wärmeener gieabgabe angestrebt. Dazu schaltet sich die Vakuumpumpe 6 - beispielsweise zeitlich an diese Phase gekoppelt - ab, wobei entweder automatisch oder durch Ventile 8; 9; 10 (abhängig vom Wirkungsprinzip der Pumpe) ein geeignetes Gas aus einem Behälter 11 oder die Umgebungsluft in das Gefäß 3 eingelassen werden. Zur Verbesserung des Wirkungsgrades der Wärmeenergie ableitung in der Adsorptionsphase kann das genannte Gas eine er höhte Wärmeleitfähigkeit aufweisen, wie beispielsweise Helium, und Energie über die am Behälter 1 angebrachten inneren Kühl rippen 12 aufnehmen. Dieses Gas kann komprimiert in einem ent sprechenden Behälter bis zu seiner Verwendung aufbewahrt werden. Luft kann auch durch eine entsprechende Vorrichtung bewegt wer den und dadurch ebenfalls eine größere Wärmemenge pro Zeit einheit an die mit der Kühlvorrichtung 13 versehenen Außenseiten des Gefäßes 3 abgeben.During the adsorption phase and consequently interruption of the external energy supply, the most effective heat energy release is sought. For this purpose, the vacuum pump 6 switches off - for example, temporally coupled to this phase - either automatically or through valves 8 ; 9 ; 10 (depending on the principle of operation of the pump) a suitable gas from a container 11 or the ambient air can be let into the vessel 3 . To improve the efficiency of the heat energy dissipation in the adsorption phase, the gas can have an increased thermal conductivity, such as helium, and absorb energy via the inner cooling ribs 12 attached to the container 1 . This gas can be stored in a compressed container until it is used. Air can also be moved by a corresponding device and thus also deliver a larger amount of heat per unit time to the outside of the vessel 3 provided with the cooling device 13 .
Im Gefäß 3 kann die Luft vom Einlaßventil 8 entweder über das Absperrventil 9 infolge einer Schornsteinwirkung zum Auslaßven til 14 gelangen oder aber über die beispielsweise als Ventila tor genutzte Vakuumpumpe 6 und deren Ventil 10.In the vessel 3 , the air from the inlet valve 8 can either pass through the shut-off valve 9 as a result of a chimney effect to the Auslaßven valve 14 or via the vacuum pump 6 used for example as a ventila tor and its valve 10 .
Zur beispielhaften Nutzung in Verbindung mit einem Kühlaggregat ist die erfindungsgemäße Vorrichtung mit einem bekannten System (vgl. DE-OS 35 12 805) über eine Leitung 15 verbunden. In einem Kondensator 16 kondensiert in der Desorptionsphase das ausge triebene dampfförmige fluide Medium und gelangt in den Verdamp fer 17, der einen geringeren Innendruck aufweist als die Vor richtung 1. Dies wird dadurch ermöglicht, daß das in der An fangsphase des Desorptionsprozesses ausgetriebene fluide Medium durch Sperrung des direkten Weges durch Ventil 19 zwischen Vor richtung 1 und Verdampfer 17 über den Kondensator 16 geführt wird, der über eine Leitung 20 mit dem Verdampfer 17 verbunden ist. In der auf die Desorptionsphase nach Abkühlung der absor bierenden oder adsorbierenden Medien 2 folgenden Adsorptions phase entsteht im Verdampfer ein Unterdruck, infolgedessen die Verdampfungswärme des fluiden Mediums dem Kühlbehälter 21 ent zogen wird. Dadurch wird durch Schließen des Ventils 18 das im Verdampfer 17 befindliche gasförmige Medium in das in der Vor richtung 1 befindliche absorbierende oder adsorbierende Medium 2 transportiert. Dieser Prozeß entzieht dem Kühlbehälter 21 die nutzbare Wärmemenge.For exemplary use in connection with a cooling unit, the device according to the invention is connected to a known system (cf. DE-OS 35 12 805) via a line 15 . In a condenser 16, the expelled vaporous fluid medium condenses in the desorption phase and passes into the evaporator 17 , which has a lower internal pressure than the device 1 . This is made possible by the fact that the fluid medium expelled in the initial phase of the desorption process is blocked by blocking the direct path through valve 19 between device 1 and evaporator 17 via the condenser 16 , which is connected via a line 20 to the evaporator 17 . In the adsorption phase following the desorption phase after cooling of the absorbing or adsorbing media 2, a negative pressure is created in the evaporator, as a result of which the heat of vaporization of the fluid medium is removed from the cooling container 21 . As a result, by closing the valve 18, the gaseous medium located in the evaporator 17 is transported into the absorbing or adsorbing medium 2 located in the device 1 . This process extracts the usable amount of heat from the cooling container 21 .
