Description
UMLAUFKOLLEKTORCIRCULATION COLLECTOR
Die Erfindung geht aus von einem Verfahren zur Optimierung des Konversionsfaktors bei der Gewinnung thermischer Energie aus Abwärmeprozessen zugunsten eines Wärmespeichers(- verbrauchers). Zur Ausführung des Verfahrens wird eine Vorrichtung (Umlaufkollektor) (Anspruch 1) vorgeschlagen.The invention is based on a method for optimizing the conversion factor in the production of thermal energy from waste heat processes in favor of a heat store (consumer). A device (circulation collector) (claim 1) is proposed for carrying out the method.
Nach dem Stand der Technik wird versucht, im Bereich der Ladung des Speichers (US 4,409,959) Schwerkraftsysteme einzusetzen. Die Ladung des Speichers erfolgt über einen externen Wärmetauscher, der die Zirkulation des Wärmeträgerfluids im Kollektorkreislauf von dem Sekundärkreislauf hydraulisch trennt. Eine Umkehrung des Wärmetransports aus dem Wärmetauscher in den Kollektor wird durch ein Ventil verhindert. Eine zusätzliche Laderegelung ist je nach Ausführung nicht erforderlich. Nachteil des Verfahrens ist neben den Kosten des Wärmetauschers und dessen eingeschränkter Wärmeleistung die kontinuierlich hohe Temperatur der Leitungen bei nur geringer Fluidströmung im Kollektor.According to the prior art, attempts are made to use gravity systems in the area of the storage charge (US Pat. No. 4,409,959). The storage tank is charged via an external heat exchanger, which hydraulically separates the circulation of the heat transfer fluid in the collector circuit from the secondary circuit. A valve prevents a reversal of the heat transport from the heat exchanger into the collector. An additional charge control is not necessary depending on the version. In addition to the cost of the heat exchanger and its limited heat output, the disadvantage of the method is the continuously high temperature of the lines with only a low fluid flow in the collector.
Weiter gibt der Stand der Technik eine Laderegelung des Speichers (US 4,531 ,510) auf der Basis eines externen, bidirektionalen Thermo-Syphon-Ventils wieder. Die Ladung des Speichers erfolgt auf der Grundlage der temperaturabhängigen Dichte des Wärmeträgerfluids. Das bidirektionale Thermo-Syphon-Ventil arbeitet als 3-Wege-Ventil und schaltet entspechend den Temperaturen der zugeführten Wärmeträgerfluide zwischen zwei Betriebszuständen um: 1. Ladung des Speichers, 2. Zirkulation im Kollektorkreislauf. Nachteil des Verfahrens ist neben den Kosten des externen Thermo-Syphon-Ventils zum einen dessen eingeschränkte Wärmeleistung und die dem Ladevorgang entgegenwirkende, zwanghafte Strömung des Kollektorkreislaufs. Die begrenzte Wärmeleistung beruht auf einem zur Vermeidung von Verwirbelungen im Thermo-Syphon-Ventil eingeschränkten Volumenstrom im Kollektorkreislauf, der sich neben den kontinuierlich hohen Leitungstemperaturen nachteilig auf den Wirkungsgrad des Gesamtsystems auswirkt.Furthermore, the prior art reproduces a charge control of the memory (US Pat. No. 4,531,510) based on an external, bidirectional thermosiphon valve. The storage tank is charged on the basis of the temperature-dependent density of the heat transfer fluid. The bidirectional thermo-siphon valve works as a 3-way valve and switches according to the temperatures of the supplied heat transfer fluids between two operating states: 1. charging the storage tank, 2. circulation in the collector circuit. In addition to the costs of the external thermosiphon valve, the disadvantages of the method are its limited heat output and the compulsory flow of the collector circuit which counteracts the charging process. The limited Heat output is based on a volume flow in the collector circuit restricted to avoid turbulence in the thermo-siphon valve, which, in addition to the continuously high line temperatures, has a negative effect on the efficiency of the overall system.
Es sind Systeme bekannt, die durch drehzahlgeregelte Pumpen und Bypaßsysteme auf der Grundlage einer geregelten, kontinuierliche Strömung des Wärmeträgerfluids versuchen den Ertrag thermischer Solaranlagen zu verbessern. Gemeinsamer Nachteil dieser Verfahren ist neben den Kosten der Bauteile und dem hohen Strömungswiderstand in den Verbindungsleitungen und dem Wärmetauscher die Addition der Leitungsverluste zu den Kollektorverlusten.Systems are known which attempt to improve the yield of thermal solar systems by means of speed-controlled pumps and bypass systems based on a regulated, continuous flow of the heat transfer fluid. A common disadvantage of these methods is, in addition to the costs of the components and the high flow resistance in the connecting lines and the heat exchanger, the addition of the line losses to the collector losses.
Die Erfindung mit den kennzeichnenden Merkmalen der Ansprüche hat demgegenüber die Vorteile, daß die Fördereinrichtung (21) nur dann eingeschaltet wird, wenn eine konventionelle oder Energiedifferenzregelung den zu erwartenden Energieeintrag in den Speicher (4) positiv bewertet.The invention with the characterizing features of the claims has the advantages that the conveyor (21) is only switched on when a conventional or energy difference control evaluates the expected energy input into the memory (4) positively.
Nach einer vorteilhaften Ausgestaltung des Verfahrens ist die Umlaufleitung (14) (innerhalb des Energieraums Kollektor (1)) beschattet und mit Kühlkörpern, sowie einem (regelbaren) Ventil (16) versehen. Bei Beginn der Einwirkung der Wärmestrahlung setzt sich in den Absorberröhren (12) und in der Umlaufleitung (14) eine auf der temperaturabhängigen, unterschiedlichen Dichte des Mediums beruhende Schwerkraftzirkulation in Gang, die den Übergang der Wärme vom Absorber (11) in das Wärmeträgerfluid beschleunigt und damit den Wirkungsgrad des Kollektors (1) verbessert. Solange die Einschaltbedingung eines Regelalgorithmus die Fördereinrichtung (21) einschaltet, verhindert das Ventil (16) die Strömung des Wärmeträgerfluids durch die Umlaufleitung (14). Der kontinuierliche Fluß in den Absorberröhren bleibt bestehen, der Wirkungsgrad wird weiter verbessert. Schaltet die Ausschaltbedingung eines Regelalgorithmus die Fördereinrichtung (21) ab, gibt das Ventil (16) die Schwerkraftzirkulation in der Umlaufleitung (14) frei. Das Ventil (22) in der Leitung (2) sperrt die Leitung (2) und führt das Wärmeträgerfluid ausschließlich dem Kollektor zu (Fig. 1/4). Die Erfindung mit den kennzeichnenden Merkmalen der Ansprüche hat die Vorteile, daß der Konversationsfaktor des Absorbers und damit der Wirkungsgrad des Kollektors durch diesen kontinuierlichen Fluß des Wärmeträgerfluids unter Ausschaltung der Leitungsverluste wesentlich verbessert wird.According to an advantageous embodiment of the method, the circulation line (14) (within the energy space collector (1)) is shaded and provided with heat sinks and a (controllable) valve (16). When heat radiation begins to act, a gravity circulation based on the temperature-dependent, different density of the medium starts in the absorber tubes (12) and in the circulation line (14), which accelerates and transfers the heat from the absorber (11) into the heat transfer fluid thus improving the efficiency of the collector (1). As long as the switch-on condition of a control algorithm switches on the conveyor (21), the valve (16) prevents the flow of the Heat transfer fluid through the circulation line (14). The continuous flow in the absorber tubes remains, the efficiency is further improved. If the switch-off condition of a control algorithm switches off the conveying device (21), the valve (16) enables the circulation of gravity in the circulation line (14). The valve (22) in line (2) blocks line (2) and supplies the heat transfer fluid exclusively to the collector (Fig. 1/4). The invention with the characterizing features of the claims has the advantages that the conversation factor of the absorber and thus the efficiency of the collector is significantly improved by this continuous flow of the heat transfer fluid with elimination of the line losses.
Nach einer weiteren vorteilhaften Ausgestaltung einer Vorrichtung zur Durchführung des Verfahrens wird die Schwerkraftzirkulation im Kollektor (1) und der Umlaufleitung (14) durch eine Fördereinrichtung (18) unterstützt. Nach überschreiten eines anlagenspezifischen Energiestroms dE/dt auf den Absorber (11), der beispielsweise durch Erfassen der Temperaturgradienten innerhalb des Absorbers ermittelt wird, schaltet die Fördereinrichtung (18) ein und fördert das Wärmeträgerfluid durch die Umlaufleitung (14) und die Absorberröhren (12) ohne zusätzliche Leitungsverluste, d.h. Wärme- und Strömungsverluste durch den Kollektor (1). Das Ventil (22) in der Leitung sperrt die Leitung (2) so daß der gesamte Massenstrom durch den Absorber fließt (Fig. 3/4). Solange die Einschaltbedingung eines Regelalgorithmus die Fördereinrichtung (21) ein- und die Fördereinrichtung (18) ausschaltet, verhindert das Ventil (16) die Strömung des Wärmeträgerfluids durch die Umlaufleitung (14). Der kontinuierliche Fluß in den Absorberröhren bleibt bestehen, der Wirkungsgrad wird weiter verbessert. Schaltet die Ausschaltbedingung eines Regelalgorithmus die Fördereinrichtung (21) ab, gibt das Ventil (16) die Zirkulation in der Umlaufleitung (14) frei. Das Ventil (22) in der Leitung (2) sperrt die Leitung (2) und führt das Wärmeträgerfluid ausschließlich dem Kollektor zu (Fig. 4/4). Die Erfindung mit den kennzeichnenden Merkmalen der Ansprüche hat den Vorteil, daß der Konversationsfaktor des Absorbers und damit der Wirkungsgrad des Kollektors durch diesen kontinuierlichen Fluß des Wärmeträgerfluids unter Ausschaltung der Leitungsverluste wesentlich verbessert wird.According to a further advantageous embodiment of a device for carrying out the method, the gravity circulation in the collector (1) and the circulation line (14) is supported by a conveyor device (18). After exceeding a system-specific energy flow dE / dt on the absorber (11), which is determined, for example, by detecting the temperature gradients within the absorber, the conveyor device (18) switches on and conveys the heat transfer fluid through the circulation line (14) and the absorber tubes (12). without additional line losses, ie heat and flow losses through the collector (1). The valve (22) in the line blocks the line (2) so that the entire mass flow flows through the absorber (Fig. 3/4). As long as the switch-on condition of a control algorithm switches the conveying device (21) on and the conveying device (18) off, the valve (16) prevents the flow of the heat transfer fluid through the circulation line (14). The continuous flow in the absorber tubes remains, the efficiency is further improved. If the switch-off condition of a control algorithm switches off the conveying device (21), the valve (16) gives the circulation in the circulation line (14) free. The valve (22) in line (2) blocks line (2) and supplies the heat transfer fluid exclusively to the collector (Fig. 4/4). The invention with the characterizing features of the claims has the advantage that the conversation factor of the absorber and thus the efficiency of the collector is significantly improved by this continuous flow of the heat transfer fluid with elimination of the line losses.
Nach einer weiteren vorteilhaften Ausgestaltung einer Vorrichtung zur Durchführung des Verfahrens ist die Umlaufbaugruppe, bestehend aus der Umlaufleitung (14), der Fördereinrichtung (18) und dem Ventil (16) eine eigene Baugruppe, die auf konventionelle Kollektoren und Kollektorgruppen aufgeschaltet wird.According to a further advantageous embodiment of a device for carrying out the method, the circulation assembly, consisting of the circulation line (14), the conveying device (18) and the valve (16), is a separate assembly which is connected to conventional collectors and collector groups.
