Technisches GebietTechnical area
Die Erfindung stellt eine Neuentwicklung auf dem Gebiet Wärmespeicher mit Phasenwechselmaterial (englisch Phace Change Material, kurz PCM) oder Latentspeicher dar.The invention represents a new development in the field of heat storage with phase change material (English Phace Change Material, short PCM) or latent storage.
Stand der TechnikState of the art
Phasenwechselmateralien nutzen zur Wärmespeicherung die latente Wärme des Phasenübergangs zwischen fest und flüssig (Schmelzwärme). Da beim Phasenwechsel große Wärmemengen bei geringer Temperaturänderung gespeichert, bzw. frei werden, finden PCMs zur Temperaturstabilisierung und für den Bau von Wärmespeichern hoher Speicherdichte Verwendung. PCMs können auf zwei Arten in Energiespeicher angewendet werden. Entweder in Module verkapselt in dem Speicher integriert, die dann auch gleichzeitig als Wärmetauscher dienen, oder den Speicher direkt mit PCM zu befüllen und dann über einen geeigneten Wärmetauscher zu be- und entladen.Phase change materials use the latent heat of the phase transition between solid and liquid (heat of fusion) for heat storage. Since large amounts of heat are stored or released during the phase change with little change in temperature, PCMs are used for temperature stabilization and for the construction of heat storages of high storage density. PCMs can be used in energy storage in two ways. Either encapsulated in modules integrated in the memory, which then also serve as a heat exchanger, or to fill the memory directly with PCM and then loaded and unloaded via a suitable heat exchanger.
Die gegenständliche Erfindung betrifft die zweite Variante und kann z.B. den Ertrag von thermischen Solaranlagen, die der Heizungsunterstützung dienen, wesentlich verbessern.The subject invention relates to the second variant and may e.g. significantly improve the yield of solar thermal systems that support the heating system.
Vorteile der Erfindung gegenüber den bereits bekannten SystemenAdvantages of the invention over the already known systems
Als Wärmetauscher wird ein Rohrregister verwendet, dass mit einer aufwendigen Berippung die für die schlechte Wärmeleitung der PCMs notwendige große Wärmetauscher-Oberfläche besitzt. Die Speicherhülle wird der geometrischen Form der Wärmetauscher angepasst, sodaß sich ein hoher PCM-Volumsanteil von über 80% ergibt und die flache, kastenförmige Bauform eine äußerst platzsparende Unterbringung ermöglicht.As a heat exchanger, a pipe register is used that has a costly ribbing the necessary for the poor heat conduction of the PCMs large heat exchanger surface. The storage envelope is adapted to the geometric shape of the heat exchanger, so that a high PCM volume share of over 80% results and the flat, box-shaped design allows a very space-saving accommodation.
Der Wärmetauscher besitzt 2 Kreise, damit wird das gleichzeitige Laden und Entladen ermöglicht. Er besteht aus zwei Paketen in Serie geschalten, dadurch wird eine 2-stufige Wärmespeicherung ermöglicht.The heat exchanger has 2 circuits, thus enabling simultaneous charging and discharging. It consists of two packages connected in series, thus enabling a 2-stage heat storage.
Figuren-BeschreibungFigures Description
In Fig. 1 ist der Speicher im seitlichen Schnitt dargestellt.In Fig. 1 the memory is shown in lateral section.
Er besteht aus der Speicherhülle (10) mit eingebauten 1. Wärmetauscherpaket (5) und 2. Wärmetauscherpaket (6). Die Wärmetauscherpakete bestehen aus dem äußeren Wärmeträgerohr (1) mit aufgezogenen Rippen (3) zur Oberflächenvergrößerung.It consists of the storage enclosure (10) with built-in 1st heat exchanger package (5) and 2nd heat exchanger package (6). The heat exchanger packages consist of the outer heat transfer tube (1) with mounted ribs (3) to increase the surface area.
Im äußeren Wärmeträgerrohr befindet sich das innere Wärmeträgerrohr (2). Oben und unten sind die Wärmeträgerrohre mit Verteiler/Sammler (9) für das äußere Rohr und das innere Rohr (8) verbunden. Die Räume zwischen Speicherhülle, den Wärmetauschern und den Rippen (3) ist mit PCM (4) gefüllt. Im Raum zwischen den Wärmetauscherpaketen (7) dient das schlecht wärmeleitende PCM zur thermischen Trennung. Die Stege (11) dienen zur Versteifung der Speicherhülle und zur Befestigung der äußeren Verkleidung (12), bei Bedarf feuerfeste Ummantelung. Zwischen Speicherhülle und äußerer Verkleidung befindet sich Isoliermaterial (13).In the outer heat transfer tube is the inner heat transfer tube (2). Above and below the heat transfer tubes with distributor / collector (9) for the outer tube and the inner tube (8) are connected. The spaces between the storage shell, the heat exchangers and the ribs (3) is filled with PCM (4). In the space between the heat exchanger packets (7), the poor thermal conductivity PCM is used for thermal separation. The webs (11) serve to stiffen the storage enclosure and to attach the outer panel (12), if necessary, refractory sheath. Between memory shell and outer panel is insulating material (13).
In Fig. 2 ist im Schnitt der Aufbau von Verteiler/Sammler (8 und 9) ersichtlich, in Fig. 3 ist das Wärmetauscherpaket von oben gesehen gezeichnet.In Fig. 2, the construction of manifold / collector (8 and 9) can be seen in section, in Fig. 3, the heat exchanger package is drawn from above seen.
In Fig. 4 ist der Speicher von oben gesehen dargestellt, in Fig. 5 von vorne gesehen.In Fig. 4, the memory is shown viewed from above, seen in Fig. 5 from the front.
