Description
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 memory.
Phasenwechselmaterialien 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.Phase change materials use for heat storage the latent heat of the phase transition between solid and liquid (Heat of fusion). There at the phase change big amounts of heat at low temperature change stored, or become free, find PCMs for temperature stabilization and for the Construction of heat storage high storage density use.
PCMs können auf zwei Arten im 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.PCMs can be applied in energy storage in two ways. Either in Encapsulated modules integrated into the memory, which then also simultaneously as a heat exchanger serve, or to fill the memory directly with PCM and then over a suitable heat exchanger to load and unload.
Die beanspruchte Erfindung betrifft die zweite Variante und kann den Ertrag beispielsweise von thermischen Solaranlagen, die der Heizungsunterstützung dienen, wesentlich verbessern (Problemstellung).The claimed invention relates to the second variant and can the Yield, for example, of solar thermal systems that serve the heating support, significantly improve (problem definition).
Dies wird dadurch erreicht, dass die Wärmetauscher ein äußeres Wärmeträgerrohr (erster Kreis) und ein inneres Wärmeträgerrohr (zweiter Kreis) aufweisen und der Wärmeübertrag entweder vom zweiten Kreis auf den ersten Kreis und in weiterer Folge über die Wärmetauscherrippen auf das PCM (Phasenwechselmaterial) oder vom PCM (Phasenwechselmaterial) über die Wärmetauscherrippen auf den ersten Kreis erfolgt (Anspruch 1).This is achieved in that the heat exchanger is an outer heat transfer tube (first circle) and an inner heat transfer tube (Second circle) and the heat transfer from either of the second Circle on the first circle and subsequently on the heat exchanger fins on the PCM (phase change material) or the PCM (phase change material) on the heat exchanger fins on the first circle takes place (claim 1).
Es ist zweckmäßig, wenn die Wärmetauscher aus zwei Paketen bestehen, die durch einem mit PCM befüllten Zwischenraum thermisch getrennt sind und so eine zweistufige Ladung und Entladung ermöglichen.It is appropriate if the heat exchangers consist of two packets that pass through a space filled with PCM are thermally separated and thus allow a two-stage charge and discharge.
Eine Ausführungsform ist dadurch gekennzeichnet, dass die Wärmeträgerrohre in beliebiger Anzahl oben und unten in Verteiler/Sammler münden, wobei das innere Rohr durch das Verteilerrohr hindurchgeführt wird.A embodiment is characterized in that the heat transfer tubes in any number at the top and bottom of the distributor / collector, with the inner tube is passed through the manifold.
Es ist zweckmäßig, wenn die Wärmetauscher in einer drucklosen Speicherhülle eingebaut sind, die mit Stegen versteift ist, die auch zur Befestigung einer äußeren Verkleidung, bzw. feuerfesten Ummantelung dienen, wobei im Raum zwischen Speicherhülle und äußerer Verkleidung Isoliermaterial angebracht werden kann.It is appropriate if the heat exchangers in a pressureless storage case are built in, which is stiffened with webs, which also for attachment an outer panel, or refractory sheath serve, wherein in the space between the storage shell and outer panel Insulating material can be attached.
Als Wärmetauscher wird ein Rohrregister verwendet, das mit einer aufwändigen Berippung die im Hinblick auf 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 (Anspruch 7). Der Wärmetauscher besitzt zwei Kreise. Damit wird das gleichzeitige Laden und Entladen ermöglicht. Er besteht aus zwei in Serie geschaltenen Paketen. Dadurch wird eine zweistufige Wärmespeicherung ermöglicht.When heat exchangers a pipe register is used, which with an elaborate ribbing which is necessary in view of the poor heat conduction of the PCMs size Heat exchanger surface has. The storage enclosure 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 a very space-saving Accommodation allows (Claim 7). The heat exchanger has two circles. This will be the simultaneous loading and unloading allows. It consists of two packages in series. This will a two-stage heat storage allows.
