Abstract

The transformation- and storage block (1) has multiple channels (2), where the channel walls consist of a sorptive functional layer (7), which is a permanent casing for a storage material (9). Another functional layer (8) acts as a binder between the former functional layer and the storage material. The latter functional layer is an elastomer, which balances the volume change of the sorptive functional layer against the storage material. The storage material is made of a pourable polymer with low shrinkage.

Description

[0001] Die vorliegende Erfindung betrifft einen Übertrager- und Speicherblock für sensible und latente Wärme sowie für Stoffe bei erzwungener Strömung eines Fluides durch eine Vielzahl von Kanälen. Der Übertrager- und Speicherblock wird dabei abwechselnd von einem Fluid mit hohem Potential (Temperatur, Stoffkonzentration) und einem Fluid mit niederem Potential im Gegenstrom durchströmt. Dieser Übertrager- und Speicherblock ist auch als Rotationswärmeübertrager mit Sorption oder als Umschaltspeicher bekannt und wird z.B. zur regenerativen Wärme- und Feuchterückgewinnung in Lüftungs- und Klimaanlagen verwendet. The present invention relates to a transmitter and memory block for sensitive and latent heat and for substances in forced flow of a fluid through a plurality of channels. The transformer and storage block is alternately flowed through by a fluid with high potential (temperature, substance concentration) and a fluid with low potential in countercurrent. This transformer and storage block is also known as a rotary heat exchanger with sorption or as a switching memory and is e.g. used for regenerative heat and moisture recovery in ventilation and air conditioning systems.

[0002] Es sind mehrere gattungsgemässe Übertrager sowie Speicher von Wärme und Stoffen bekannt. There are several generic transformers and storage of heat and substances known.

[0003] Die Patentschriften EP 0 957 320 Heat exchanger element, EP 1 796 819 Production of wound storage material for rotational heat exchangers und DE 10 2005 003 543 Feuchtigkeits- und/oder Wärmeaustauschvorrichtung z.B. Plattenwärmeaustauscher, Sorptionsrotor Adsorptionsentfeuchtungsrotor od. dgl., beschreiben Wärmerückgewinnungselemente, hergestellt aus dünnwandigen Bändern, einmal glatt und einmal gewellt. Diese mit Sorptionsmaterial beschichteten Bänder werden zu einem Rotor gewickelt. Nachteile dieser Ausführung sind der schlechte Wärmeübergang bezogen auf die Brutto-Bandoberfläche und die ungünstige Kanalform. Die Luftkanäle werden dabei durch die 2 Bänder gebildet. Bei den Verbindungsstellen dieser Bänder entstehen relevante Anteile von nicht genutzten Oberflächen. In diesen Kanalecken ist die Spülung bei laminarer Strömung unvollständig. Dies führt zu einer ungewünschten Stoffübertragung, z.B. Gerüche, von der Abluft auf die Zuluft. Speziell bei kleinem hydraulischem Durchmesser sind diese Nachteile stark ausgeprägt. Diese Kanalecken sind zudem ungünstig bezüglich dem Verschmutzungsverhalten des Wärmeaustauschers. Bei Verwendung von metallischen Bändern, z.B. Aluminium, mit der für die Wärmespeicherung notwendigen Materialdicke, wird zudem der Wirkungsgrad infolge der axialen Wärmeleitung reduziert. EP 0 957 320 Heat exchanger element, EP 1 796 819 Production of wound storage material for rotational heat exchangers and DE 10 2005 003 543 moisture and / or heat exchange device, e.g. Plate heat exchanger, sorption rotor Adsorptionsentfeuchtungsrotor od. Like. Describe heat recovery elements made of thin-walled bands, once smooth and once wavy. These sorbent-coated ribbons are wound into a rotor. Disadvantages of this design are the poor heat transfer based on the gross strip surface and the unfavorable channel shape. The air channels are formed by the 2 bands. At the junctions of these bands, relevant proportions of unused surfaces are created. In these channel corners, lavage at laminar flow is incomplete. This leads to unwanted mass transfer, e.g. Odors, from the exhaust air to the supply air. Especially with a small hydraulic diameter, these disadvantages are pronounced. These channel corners are also unfavorable with regard to the soiling behavior of the heat exchanger. When using metallic bands, e.g. Aluminum, with the necessary for the heat storage material thickness, the efficiency is also reduced due to the axial heat conduction.

[0004] Die Patentschrift DE 10 2011 0 011 181 Wärme- und/oder Feuchteaustauschelement beschreibt einen Plattenwärmeübertrager als Umschaltspeicher. Dünnwandige Platten oder Bänder mit Abstandsleisten aus Kunststoff werden zu einem Wärmeübertrager gestapelt und verklebt. Der Feuchteaustausch erfolgt über die Kondensatphase beim Abkühlzyklus. Nachteile dieser Ausführung sind der geringe Feuchtewirkungsgrad, speziell bei einem geringen Kondensationspotential, sowie der Materialaufwand für die Erreichung eines druckstabilen Wärmeübertragers. Bei einem Feuchteaustausch mit freiem Wasser besteht der Nachteil, dass wasserlösliche Stoffe und Gerüche übertragen werden. Bei dieser Ausführung sind Massnahmen für die Kondensatableitung und gegen die Vereisung notwendig. Der Druckverlust ist wegen der vielen Abstandshalter und der ungünstigen Kanalform nicht vorteilhaft. The patent DE 10 2011 0 011 181 heat and / or moisture exchange element describes a plate heat exchanger as Umschaltspeicher. Thin-walled panels or strips with plastic spacer strips are stacked and glued to form a heat exchanger. The moisture exchange takes place via the condensate phase during the cooling cycle. Disadvantages of this design are the low moisture efficiency, especially at a low condensation potential, as well as the cost of materials for the achievement of a pressure-stable heat exchanger. In a wet exchange with free water has the disadvantage that water-soluble substances and odors are transmitted. With this version measures for the condensate drainage and against the icing are necessary. The pressure loss is not advantageous because of the many spacers and the unfavorable channel shape.

[0005] Obiges gilt auch für die bekannten Ausführungen mit spiralförmig aufgerollten Bändern. The above also applies to the known designs with spirally rolled-up bands.

[0006] Die Patentschriften WO 2004 113 816 Wabenkörper für thermische Abgasbehandlung, KR10 2012 025 057 Continuity turning type regenerative heat exchanger und CN 000 101 898 498 Evapuration type automobile parking ventilating and cooling System, beschreiben Übertrager aus Keramik mit wabenförmigen Kanälen für Fluide mit hohen Temperaturen und für Stoffe mit korrosiven Eigenschaften. Keramik ist für die Stoffübertragung von z.B. Wasser im Temperaturbereich kleiner 0°C nicht geeignet. Das in den Poren gespeicherte H2O vereist und sprengt das keramische Material beim Auftauprozess. Der Feuchteaustausch erfolgt über die Kondensatphase. Die vorgängig beschriebenen Nachteile geringer Feuchtewirkungsgrad, Geruchsübertragung, Kondensatableitung und Vereisungsschutzmassnahmen gelten auch für diese Ausführung. Zudem ist die Herstellung dieser Übertrager mit Kanälen mit kleinem hydraulischem Durchmesser aufwändig. Patents WO 2004 113 816 Honeycomb body for thermal exhaust gas treatment, KR10 2012 025 057 Continuity turning type regenerative heat exchanger and CN 000 101 898 498 Evapuration type describe automotive transformers with honeycomb channels for fluids with high Temperatures and for substances with corrosive properties. Ceramics are suitable for the mass transfer of e.g. Water in the temperature range below 0 ° C not suitable. The H2O stored in the pores ices up and breaks up the ceramic material during the thawing process. The moisture exchange takes place via the condensate phase. The previously described disadvantages of low moisture efficiency, odor transmission, condensate drainage and anti-icing measures also apply to this design. In addition, the production of these transformers with channels with a small hydraulic diameter is expensive.

[0007] Die Patentschrift CH 700 341, Wärmeübertrager mit einem Helix-Kanal für eine erzwungene Strömung, beschreibt einen helixförmigen Fluidkanal mit 3 Kanalabschnitten für die verbesserte Wärme- und Stoffübertragung. Die Kanaloberfläche ist mit einer Funktionsschicht für die Stoffübertragung ausgeführt. Diese Ausführung beschreibt eine vorteilhafte Ausführung für eine hohe spezifische Übertragungsleistung. Die Herstellung der helixförmigen Kanäle ist aber recht aufwändig und nur für Anwendungen, bei welchen eine hohe Leistungsdichte gefordert wird, gerechtfertigt. The patent CH 700 341, forced-flow helix-type heat exchanger, describes a helical fluid channel having 3 channel sections for improved heat and mass transfer. The channel surface is designed with a functional layer for the mass transfer. This embodiment describes an advantageous embodiment for a high specific transmission power. However, the production of the helical channels is quite complex and justified only for applications in which a high power density is required.

[0008] Die Erfindung hat die Aufgabe, eine verbesserte Ausführung eines gattungsgemässen regenerativen Übertrager- und Speicherblocks bereitzustellen. Insbesondere soll für die Ausführungen, bei welchen die Kanäle mit einem hydraulischen Durchmesser von kleiner als 3 mm notwendig sind, die spezifische Übertragungsleistung verbessert und die ungewünschte Stoffübertragung, z.B. Gerüche, reduziert werden. The invention has the object to provide an improved embodiment of a generic regenerative transformer and memory block. In particular, for embodiments in which the channels with a hydraulic diameter of less than 3 mm are necessary, the specific transmission performance should be improved and the unwanted mass transfer, e.g. Odors, to be reduced.

[0009] Der erfindungsgemässe Übertrager- und Speicherblock ist dadurch gekennzeichnet, dass die Kanäle eine für die Anwendung und Herstellung optimierte Geometrie aufweisen und die Kanalwände durch wenigstens eine Funktionsschicht erzeugt werden. Der erfindungsgemässe Übertrager- und Speicherblock besteht nicht wie bisher bekannt aus einzelnen Bändern oder Platten mit Beschichtung, sondern ist ein Block aus einem Speichermaterial mit einer Vielzahl von Kanälen. Die Funktionsschichten erzeugen dabei die verlorene Schalung für das Speichermaterial. Die erste Funktionsschicht ist sorptiv wirksam. Die zweite Funktionsschicht ist z.B. ein Binder, welcher auf die Art des Sorptionsmaterials und das Speichermaterial abgestimmt ist. Für Anwendungen mit hohen hygienischen Anforderungen kann in das Ausgangsmaterial für die erste oder zweite Funktionsschicht mit einem antimikrobiell wirkenden Stoff, z.B. Silberionen oder Nanosilber, gemischt werden. The transformer according to the invention and memory block is characterized in that the channels have an optimized for the application and production geometry and the channel walls are generated by at least one functional layer. The transformer and memory block according to the invention does not consist of individual tapes or plates with a coating, as hitherto known, but is a block of a memory material with a multiplicity of channels. The functional layers thereby generate the lost formwork for the storage material. The first functional layer is sorptively effective. The second functional layer is e.g. a binder which is tailored to the type of sorbent material and the storage material. For applications with high hygienic requirements, the starting material for the first or second functional layer with an antimicrobial agent, e.g. Silver ions or nanosilver.

[0010] Diese vorteilhafte Ausführung des Übertrager- und Speicherblocks ermöglicht eine einfache Herstellung ohne aufwändige Verbindungen von Bändern oder Platten. Es sind keine Abstandsprofile (Plattenwärmeübertrager) oder Naben (Rotoren) notwendig. Die Kanalgeometrie kann dabei je nach Aufgabenstellung beliebig gewählt werden und wird nicht durch verformte und gestapelte Bleche gebildet. Die Funktionsschichten können z.B. mit einem mehrstufigen Tauchverfahren aufgebaut werden. Dabei besteht der Tauchkern aus einer Vielzahl von Stäben, welche die gewünschte Kanalgeometrie aufweisen. Bei einer vorteilhaften Kanalform, z.B. kreisförmig oder wabenförmig, entstehen keine Ecken, welche nur schwer gespült werden können. Durch die Wahl der Dicke und der spez. Wärme des Speichermaterials kann der Speicher je nach Anforderung dimensioniert werden. Bei Verwendung von Kunststoffen als Speichermaterial ist die Wärmeleitung in axialer Richtung geringer als bei einem metallischen Trägermaterial. This advantageous embodiment of the Übertrager- and memory block allows easy production without complex connections of bands or plates. No spacer profiles (plate heat exchangers) or hubs (rotors) are necessary. The channel geometry can be chosen arbitrarily depending on the task and is not formed by deformed and stacked sheets. The functional layers may e.g. be built with a multi-stage dipping process. In this case, the plunger consists of a plurality of rods, which have the desired channel geometry. In an advantageous channel shape, e.g. circular or honeycomb, no corners, which are difficult to flush. By choosing the thickness and the spec. Heat of the storage material, the memory can be sized according to requirements.
