Abstract
Description
Die Erfindung, betrifft einen wassergefüllten Speicherbehälter, dessen Inhalt mit einer Wärmepumpe Energie entzogen wird, bis er ganz, oder teilweise zu Eis gefroren ist.The invention relates to a water-filled storage tank whose contents are deprived of energy by a heat pump until it is completely or partially frozen in ice.
Mit der entnommenen Wärme können in der kalten Jahreszeit Wohn- oder Gewerberäume beheizt werden; umgekehrt ist es möglich, diese im Sommer zu kühlen, wobei dem Eisdepot über einen Kaltwassersatz eine entsprechende Wärmemenge zugeführt wird, um es wieder zu flüssigem Wasser zu schmelzen, worauf dessen Wärmepotential erneut im Winter zu Heizzwecken zur Verfügung steht.With the extracted heat residential or commercial spaces can be heated in the cold season; Conversely, it is possible to cool them in the summer, wherein the ice storage on a chiller, a corresponding amount of heat is supplied to melt it back to liquid water, whereupon its heat potential is available again in the winter for heating purposes.
Damit ist es möglich, die elektrische Energie, die zum Betrieb der Wärmepumpe eingesetzt wurde, sozusagen ein zweites Mal zu Kühlzwecken zu nutzen, oder, anders herum betrachtet, die Abwärme einer Gefriertruhe für Lebensmittel oder einer Raumklimatisierung zur Warmwasserbereitung für ein Hotel oder eine Restaurantküche. Des weiteren kann mit dem Eiswasser eine Kühltheke für Lebensmittel direkt betrieben werden, und bedarf somit nicht eines eigenen Kühlaggregats.Thus, it is possible to use the electrical energy that was used to operate the heat pump, so to speak a second time for cooling purposes, or vice versa, the waste heat of a freezer for food or air conditioning for hot water for a hotel or a restaurant kitchen. Furthermore, a refrigerated counter for food can be operated directly with the ice water, and thus does not require its own refrigeration unit.
Wenn die sommerliche Kühllast nicht ausreicht, den gesamten Eisvorrat zu schmelzen, kann mit einem Solarkollektor zusätzliche Wärme in den Eisspeicher eingetragen werden, der Wirkungsgrad dieses Kollektors wird durch die niedrigen Rücklauftemperaturen erhöht. Bei einer entsprechenden Dimensionierung des Eisspeichers wird dieser somit zu einem Saisonspeicher für thermische Solaranlagen.If the summer cooling load is not sufficient to melt the entire ice stock, additional heat can be added to the ice storage tank with a solar collector, the efficiency of this collector is increased by the low return temperatures. With a corresponding dimensioning of the ice storage this is thus a seasonal storage for solar thermal systems.
Die Investition für den Eisspeicher macht sich sehr schnell bezahlt, da ja andere Kosten, z. B. Für das Schlagen eines Grundwasserbrunnens, oder für die Verlegung von Rohrschlangen im Erdreich, zur Erschliessung einer Wärmequelle entfallen. Im Gegensatz zur saisonalen Speicherung von Solarwärme in einem Heisswasserspeicher muss ein Eisspeicher nicht isoliert werden, es ist sogar günstig, wenn er als Erdspeicher angelegt wird und dem umgebenden Erdreich im Winter zusätzliche Wärme entzieht, und mit dieser unterkühlten Umgebung im Sommer den Eisvorrat kalt hält.The investment for the ice storage is paid very quickly, since other costs, such. B. For hitting a groundwater well, or for the laying of pipe coils in the ground, account for the development of a heat source. In contrast to the seasonal storage of solar heat in a hot water storage, an ice storage does not need to be insulated, it is even beneficial if it is designed as a ground storage and the surrounding soil in the winter extracts additional heat, and keeps the ice stock cold with this supercooled environment in the summer.
Es ist bekannt, ihn aus vorgefertigten Betonringen in Form einer Zisterne mit geringem wirtschaftlichen Aufwand zu erstellt Noch wirschaftlicher ist seine Erstellung mit einem Foliensack, welcher im Erdreich eingegraben wird.It is known to create him from prefabricated concrete rings in the form of a cistern with little economic effort to even more economical is its creation with a foil bag, which is buried in the ground.
Diese Bauform wird in der hier vorliegenden Patentanmeldung näher beschrieben.This design is described in more detail in the present patent application.
Die Wärmeentnahme mit Hilfe einer Wärmepumpe, unterhalb der Phasenumwandlungs-temperatur hat den Vorteil, daß zusätzlich zur sensiblen Wärme des Wasservorrats auch dessen Latentwärme entnommen werden kann, sie entspricht in etwa der sensiblen Wärme für einen Temperaturhub von 80°K. Die Speicherkapazität verdoppelt sich also gegenüber einem sensiblen Warmwasserspeicher, die Nutzung zu Kühlzwecken wird überhaupt nur so möglich.The heat removal by means of a heat pump, below the phase transition temperature has the advantage that in addition to the sensitive heat of the water supply and its latent heat can be removed, it corresponds approximately to the sensible heat for a temperature of 80 ° K. The storage capacity is thus doubled compared to a sensitive hot water storage tank, the use for cooling purposes is only possible in this way.
Allerdings erfordert die Eisbildung eine besondere Konstruktion des Wärmetauschers, bzw. des Verdampfers der Wärmepumpe, da andernfalls die an seiner Oberfläche sich bildende Eisschicht den Wärmestrom behindert.However, the formation of ice requires a special construction of the heat exchanger or the evaporator of the heat pump, since otherwise the ice layer forming on its surface hinders the heat flow.
Eine Lösung dieses Problems wird in der
Auch die
Der in der
Die
Die so entstehende Eisschicht wird bei Erreichen einer bestimmten Dicke vom Absorber abgelöst, indem dieser kurzzeitig auf den Verflüssiger der Wärmepumpe umgeschaltet und somit erwärmt wird.The resulting ice layer is replaced when it reaches a certain thickness of the absorber by this is briefly switched to the condenser of the heat pump and thus heated.
Diese zyklische Erwärmung des Wärmetauschers führt aber zu Energieverlusten, und damit zu einem schlechten Wirkungsgrad des Gesamtsystems.However, this cyclic heating of the heat exchanger leads to energy losses, and thus to a poor efficiency of the overall system.
Es wird deshalb hier vorgeschlagen, die Oberfläche des Verdampfers der Wärmepumpe mit einer Beschichtung zu versehen, welche die Bildung, und damit auch das Anhaften von Eis unterbindet.It is therefore proposed here, the surface of the evaporator of the heat pump with a coating which prevents the formation, and thus the adhesion of ice.
Dem Speichermedium Wasser wird dann nicht direkt an der Oberfläche des Verdampfers der Wärmepumpe seine Kristallisationsenthalpie entzogen, sondern indirekt, und erst nachdem das unter den Gefrierpunkt abgekühlte Wasser diese Oberfläche verlassen hat, und daraufhin im umgebenden Speicherwasser zu Eiskristallen gefriert.The storage medium water is then not deprived of its crystallization enthalpy directly at the surface of the evaporator of the heat pump, but indirectly, and only after the cooled below freezing point water has left this surface, and then freezes in the surrounding storage water to ice crystals.
Erreicht wird dieses Ziel durch eine geeignete, mikro- bzw. nanostrukturierte Oberfläche des Verdampfers, von welcher das Wasser abgestossen wird, so dass sich auf ihr auch bei Minusgraden kein Eis bildet. Diese Oberfläche kann sowohl direkt auf dem Material des Verdampfers erzeugt werden, als sie auch in Form einer Folie mit entsprechend behandelter Oberfläche auf ihm angebracht werden kannThis goal is achieved by a suitable, micro- or nanostructured surface of the evaporator, from which the water is rejected, so that no ice forms on it even at freezing temperatures. This surface can be produced both directly on the material of the evaporator, as it can be mounted in the form of a film with a correspondingly treated surface on it
Der Vorgang der indirekten Eisbildung wird untenstehend anhand der Zeichnungen näher erläutertThe process of indirect ice formation is explained below with reference to the drawings
Da zum Zeitpunkt dieser Anmeldung nur mikro- bzw. nanostrukturierte Oberflächen bekannt sind, welche die Eisbildung zu 90% verhindern, wird in d. Unteransprüchen 2. u. 3. vorgeschlagen, diese Oberfläche auf einer Folie aus geeignetem Material anzubringen, welche zyklisch 1 periodisch mithilfe eines Trennfluids von der Oberfläche des Verdampfers abgehoben werden kann. Dadurch wird die Ablösung von Eiskristallen, welche der Oberfläche evtl trotzdem anhaften, erreicht.Since at the time of this application only micro- or nanostructured surfaces are known, which prevent the formation of ice to 90%, in d.
Indem die Folie verformt, und/oder durch das Trennfluid über den Gefrierpunkt v. Wasser erwärmt wird, lösen sich evtl. auf ihr befindliche Eiskristalle von ihr ab.By deforming the film, and / or by the separating fluid above the freezing point v. Water is heated, possibly dissolve on her ice crystals from it.
