Description
Die Erfindung betrifft einen Warmwasserschichtenspeicher zur Speicherung von Wärme mit einem drucklosen Wasserspeicher und einer Einrichtung zur schichtweisen Einleitung von Warmwasser.The The invention relates to a hot water layer storage for storage of warmth with an unpressurized water reservoir and a layer-by-layer device Hot water discharge.
Die Erfindung wird vorzugsweise zur Speicherung von in Solararkollektoren erwärmtem Wasser über angewendet.The Invention is preferably used for storage in solar collectors heated Water above applied.
Im Stand der Technik sind verschiedene Warmwasserschichtenspeicher zur Speicherung von Wärme mit einem drucklosen Wasserspeicher und einer Einrichtung zur schichtweisen Einleitung von Warmwasser bekannt.in the Various hot water layers are state of the art for storing heat with an unpressurized water reservoir and a layer-by-layer device Hot water discharge known.
Zur Speicherung von Wärme ist üblich, erwärmtes Wasser mit unterschiedlich hohen Temperaturen in Warmwasserschichtenspeicher einzuleiten.to Storage of heat is common, heated Water with different temperatures in hot water stratified tanks initiate.
Zur schichtweisen Einleitung von Warmwasser in Schichtenspeicher sind verschiedene Einrichtungen bekannt, die zur Vermeidung einer Durchmischung verschiedener Temperaturschichten ein möglichst verwirbelungsarmes Einströmen von Warmwasser in eine Schicht gleicher Temperatur bewirken sollen.to Layered introduction of hot water into stratified storage tanks Various devices known to avoid mixing different temperature layers as little swirl as possible pour in of hot water in a layer of the same temperature.
Nach
Nachteilig bei diesem Schichtenspeicher ist neben dem hohen technologischen Aufwand zur Herstellung eines derartigen Schichtenspeichers und den damit verbundenen hohen Kosten der mechanische Verschleiß der höhenverstellbaren Konstruktion.adversely in this stratified storage is next to the high technological Effort to manufacture such a layer memory and associated high costs of mechanical wear of the height adjustable Construction.

Auch
aus
Nachteilig sind dabei ebenfalls sowohl der hohe technologische Aufwand zur Herstellung derartiger Schichtenspeicher sowie die damit verbundenen hohen Kosten. Außerdem ist bei diesen bekannten Lösungen die relativ hohe Strömungsgeschwindigkeit nachteilig, mit der Warmwasser aus relativ kleinen Austritten oder aus kleinen Öffnungen austritt, da auch lokale hohe Strömungsgeschwindigkeiten zu Verwirbelungen und somit zu einer Verringerung des Temperaturgefälles in den Schichtenspeichern führen.adversely are also both the high technological effort Production of such stratified storage and the associated high costs. Moreover is with these known solutions the relatively high flow rate disadvantageous with the hot water from relatively small leaks or from small openings emerges, as local high flow velocities also cause turbulence and thus a reduction in the temperature gradient in the stratified storage.
Der Erfindung liegt die Aufgabe zugrunde, einen einfach und kostengünstig herstellbaren Warmwasserschichtenspeicher zur Speicherung von Wärme anzugeben, der einen höhenmässig exakten, schichtweisen und weitgehend verwirbelungsfreien Zulauf von Warmwasser mit sehr geringen Strömungsgeschwindigkeiten erlaubt.The The invention has for its object a simple and inexpensive to produce Specify hot water layer storage for storing heat, one that is exact in terms of height, in layers and largely swirl-free inflow of hot water with very low flow rates allowed.
Erfindungsgemäß wird die Aufgabe mit den in Anspruch 1 angegebenen Merkmalen gelöst.According to the Task solved with the features specified in claim 1.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.advantageous Refinements are specified in the subclaims.
Die Erfindung weist eine Reihe von Vorteilen auf. Durch die Ausbildung eines sehr hohen und schlanken Wasserspeichers gelingt auch bei hohen Temperaturdifferenzen eine Schichtenaufbau des Speicherwassers mit geringer Temperaturgradiente. Durch die Verwendung eines Schlauches mit flexibler, poröser und wasserdurchlässiger Wandung, der oben an einen Warmwasserzulauf angeschlossen ist und bis zum Boden der Wasserspeichers reicht, gelingt eine höhenmässig exakte, schichtweise und weitgehend verwirbelungsfreie Zuführung von Warmwasser mit sehr geringen Strömungsgeschwindigkeiten.The Invention has a number of advantages. Through training a very high and slim water reservoir also works high temperature differences a stratification of the storage water with a low temperature gradient. By using a hose with more flexible, more porous and more permeable to water Wall, which is connected to a hot water inlet at the top and reaches the bottom of the water reservoir, a height-exact, Layer-by-layer and largely swirl-free feeding of Hot water with very low flow rates.
Besonders vorteilhaft ist es, eine von oben in den Warmwasserschichtenspeicher geführte Warmwasserentnahme an einen flexiblen Entnahmeschlauch anzuschließen, dessen Ende an einem Schwimmer befestigt ist, so dass selbst bei variablen Füllständen im Wasserspeicher eine Warmwasserentnahme immer von der oberen und somit wärmsten Wasserschicht möglich ist.Especially It is advantageous to store one from above in the hot water stratified tank guided Connect hot water extraction to a flexible extraction hose, the End is attached to a float, so that even with variable levels in the Water storage always takes hot water from the top and thus warmest Layer of water possible is.
Des weiteren ist zur Reduzierung des Wärmeverlustes der wärmsten (oberen) Wasserschicht nach oben eine Anordnung von mittels einer gemeinsamen, flexiblen Hülle zusammengefassten Paraffinelementen, die auf der oberen Wasserschicht im Wasserspeicher schwimmen, vorteilhaft.Furthermore, to reduce the heat loss of the warmest (upper) water layer upwards, an arrangement of by means of a common seed, flexible shell combined paraffin elements, which float on the upper water layer in the water reservoir, advantageous.
Durch die Verwendung einer Wandung aus Holz als Tragkonstruktion und als Wärmedämmung für einen flexiblen und leichten inneren Wasserspeicher aus Gummi gelingt auf besonders einfache Weise die Herstellung eines Warmwasserschichtenspeichers.By the use of a wall made of wood as a supporting structure and as Thermal insulation for one flexible and light inner water storage made of rubber succeeds the production of a hot water layer storage in a particularly simple manner.
Ein weiterer Vorteil besteht darin, dass der Speicher mit geringfügigen Anpassungen auch als Druckspeicher für Drücke bis zu 2 bar betrieben werden kann.On Another advantage is that the memory with minor adjustments also as a pressure accumulator for pressures can be operated up to 2 bar.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles näher erläutert.The The invention is explained in more detail below using an exemplary embodiment.
