Aufgabe der Erfindung ist es einen hydraulischen Temperaturdifferenzverteiler vorzuschlagen, der unabhängig von zusätzlicher Schalt- Regel- oder Meßenergie eine leistungsabhängige Volumenmengenregelung zur maximalen Energieausbeute und Begrenzung der Speichertemperatur ermöglicht.task The invention is a hydraulic temperature difference distributor to propose that independently from additional Switching control or measuring energy a performance-based Volume control for maximum energy yield and limitation the storage temperature allows.
Erfindungsgemäß wird die Aufgabe mit dem kennzeichnenden Merkmalen des Anspruch 1 gelöst.According to the invention Problem solved with the characterizing features of claim 1.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.advantageous Embodiments are described in the subclaims.
Bei der erfindungsgemäßen Vorrichtung wird die Temperatur, des im Kollektor erwärmten Mediums, von einem mechanischen Thermoelement erfasst und über das mit dem Thermoelement verbundene Ventil in den Wärmespeicher geleitet. Ein zweites Thermoelement befindet sich im Wasserkreislauf der solaren Speicherebene und ist auf eine Temperaturdifferenz zwischen der Temperatur des Mediums im Kollektorkreis und der Temperatur im Speicherkreislauf eingestellt.at the device according to the invention is the temperature of the medium heated in the collector, of a mechanical Thermocouple detected and over the valve connected to the thermocouple in the heat storage directed. A second thermocouple is located in the water cycle of the solar storage level and is due to a temperature difference between the temperature of the medium in the collector circuit and the temperature set in the memory cycle.
Bei einer Temperaturerhöhung im Kollektorkreis reagiert das Thermoelement mit einer Längenänderung und lenkt den Energiefluss in die anfordernde Ebene des Wärmespeichers. Ist jedoch die Speichertemperatur höher als die Temperatur im Kollektorkreislauf, reagiert das zweite Thermoelement mit einer Längenänderung und die Anlage wird im Umlauf betrieben.at a temperature increase in the collector circuit, the thermocouple responds with a change in length and directs the flow of energy into the requesting plane of the heat store. However, if the storage temperature is higher than the temperature in the collector circuit, the second thermocouple reacts with a change in length and the system becomes operated in circulation.
Durch dieses gleitende Öffnen und Schließen wird eine Durchflussmengenänderung erreicht und somit automatisch die Durchflussmenge im Speicher reduziert oder erhöht und der solare Kreislauf bleibt immer voll erhalten, um alle Kollektorelemente gleichmäßig zu durchströmen. Sobald ein nutzbares Energiegefälle (Differenz) vorhanden ist, erfolgt eine Abladung in der anfordernden Speicherebene. Unabhängig von der Sonneneinstrahlung oder der Größe der Kollektorfläche wird für jede solarthermische Anlage immer selbsttätig der Volumenstrom dem Energiebedarf der einzelnen Speicherebenen angepasst. Das bedeutet, bei hohem Temperatur gefälle zwischen dem Kollektorkreislauf und dem Speicher ist der Volumenstrom hoch, bei Erreichen der voreingestellten Temperaturdifferenz wird der Volumenstrom durch den Speicher stufenlos verringert, um das Wärmeträgermedium im Kollektor durch längere Verweilzeit auf ein nutzbares Energieniveau zu bringen.By this sliding opening and closing becomes a flow rate change and thus automatically reduces the flow rate in the memory or increased and the solar circuit is always fully maintained to flow through all the collector elements evenly. As soon as a usable energy gap (Difference) is present, a discharge takes place in the requesting Storage level. Independently from solar radiation or the size of the collector surface for every Solar thermal system always automatically the flow rate energy demand adapted to the individual storage levels. That means at high Temperature gradient between the collector circuit and the memory is the volume flow high, when the preset temperature difference is reached the volume flow through the store is infinitely reduced to the Heat transfer medium in the collector by longer To bring dwell time to a usable energy level.
Nach einem weiteren Merkmal kann durch Reihenschaltung für beliebig viele Speicher die Effizienz noch gesteigert werden.To Another feature can be connected in series by any number a lot of storage will increase the efficiency even more.
