Abstract

A hybrid solar energy unit is (1) controlled to optimize it for thermal or for photovoltaic use by controlling the efficiency of the circulating pump (4) within predetermined ranges, i.e., operating at 50-100% of the full range for thermal use and at 80-100% for electrical use.

Description

Die Erfindung betrifft die Steuerung einer Solaranlage nach dem Oberbegriff des Patentan­ spruchs 1.The invention relates to the control of a solar system according to the preamble of the patent saying 1.

Hybridkollektoren können aus der solaren Strahlung sowohl thermische als auch elektri­ sche Energie gewinnen. Zu diesem Zweck besitzen sie einen üblichen Absorber, aus dem das Wasser einer Solaranlage Wärme zu einem Solarspeicher transportiert. An der Ober­ fläche ist der Absorber mit bekannten Photovoltaikzellen bestückt, die der Stromerzeugung dienen. Dabei können beide Arten der Energiegewinnung gleichzeitig wirksam sein.Hybrid collectors can both thermal and electrical from the solar radiation win energy. For this purpose they have a usual absorber from which the water in a solar system transports heat to a solar storage tank. On the waiter surface of the absorber is equipped with known photovoltaic cells that generate electricity serve. Both types of energy generation can be effective at the same time.

Bei thermischen Kollektoren ist es üblich, durch eine variable Leistungsregelung der Um­ wälzpumpe den umgewälzten Solarwasser-Volumenstrom zu verändern. Das erfolgt in Abhängigkeit von den aktuellen Werten der solaren Strahlung und der Temperatur im So­ larspeicher. Dabei kann ein Modulationsbereich von beispielsweise 50 bis 100% der Pum­ penleistung variabel eingestellt werden. Je nach dem vorhandenen Wärmeangebot am Kollektor stellt sich auf diese Weise ein variabler Volumenstrom zwischen dem Mindest- und dem Höchstwert ein, der zu einer optimalen thermischen Nutzung der einstrahlenden Sonnenenergie führt.In the case of thermal collectors, it is common to use a variable output control to regulate roller pump to change the circulated solar water volume flow. That takes place in Dependence on the current values of solar radiation and the temperature in the sun larspeicher. A modulation range of, for example, 50 to 100% of the pump power can be set variably. Depending on the available heat on In this way, the collector sets a variable volume flow between the minimum and the maximum value that leads to an optimal thermal utilization of the irradiating Solar energy leads.

Der Erfindung liegt die Aufgabe zugrunde eine Steuerung, für eine Solaranlage mit einem Hybridkollektor zu schaffen, welche zu jeder Zeit eine optimale thermische und/oder elek­ trische Nutzung der solaren Strahlung ermöglicht.The invention has for its object a controller for a solar system with a To create hybrid collector, which at all times an optimal thermal and / or elec trical use of solar radiation enables.

Die erfindungsgemäße Steuerung ist gekennzeichnet durch die im Patentanspruch 1 ge­ nannten Merkmale. The control according to the invention is characterized by the ge in claim 1 mentioned characteristics.  

Die Optimierung der thermischen Nutzung erfolgt durch die an sich bekannte variable Leistungsregelung der Umwälzpumpe im Solarkreis über den komplett möglichen Modula­ tionsbereich und die Optimierung der thermischen Nutzung durch eine Leistungsregelung der Umwälzpumpe nur im oberen Modulationsbereich. Dabei empfielt sich für die Optimie­ rung der thermischen Nutzung ein Modulationsbereich von etwa 50 bis 100% der Pum­ penleistung und für die Optimierung der elektrischen Nutzung ein Modulationsbereich von etwa 80 bis 100% der Pumpenleistung.The thermal use is optimized by the variable known per se Capacity control of the circulation pump in the solar circuit via the completely possible module range and the optimization of thermal use through a power control the circulation pump only in the upper modulation range. It is recommended for the optimization thermal use a modulation range of about 50 to 100% of the pump performance and a modulation range of about 80 to 100% of the pump output.

Die erfindungsgemäße Aufgliederung der Optimierungsbereiche hat das Ergebnis, dass in der thermischen Optimierungsphase eine größtmögliche Wärmenutzung erfolgt, da der Solarwasser-Volumenstrom durch die Modulation der Pumpe an das Wärmeangebot am Kollektor angepasst ist. Bei einem geringen Volumenstrom können aber die Temperaturen am Kollektor infolge der geringeren Wärmeabfuhr ansteigen. Und diese erhöhten Tempe­ raturen am Kollektor haben einen geringeren Wirkungsgrad der Photovoltaikzellen des Hybridkollektors zur Folge. Um nun die elektrische Nutzung zu optimieren, erfolgt in dieser Betriebsphase eine Leistungsregelung der Umwälzpumpe nur im oberen Modulationsbe­ reich, vorzugsweise von etwa 80 bis 100% der Pumpenleistung. Die elektrische Optimie­ rung vermeidet also bewusst sehr niedrige Volumenströme mit der Möglichkeit eines Tem­ peraturanstiegs am Kollektor. Durch die optimale Wärmeabfuhr erfolgt eine genügende Kühlung der Photovoltaikzellen, mit einer höchstmöglichen Stromerzeugung. Eine Ver­ schlechterung des Wirkungsgrades in dieser Phase infolge zu hoher Kollektortemperaturen wird vermieden.The breakdown of the optimization areas according to the invention has the result that in the thermal optimization phase, the greatest possible use of heat takes place, since the Solar water volume flow by modulating the pump to the heat supply on Collector is adjusted. With a low volume flow, however, the temperatures can rise at the collector due to the lower heat dissipation. And this increased temp fittings on the collector have a lower efficiency of the photovoltaic cells Hybrid collector result. In order to optimize the electrical usage, this is done in this Operating phase a capacity control of the circulation pump only in the upper modulation area rich, preferably from about 80 to 100% of the pump output. The electrical optimization So deliberately avoids very low volume flows with the possibility of a tem rise in temperature at the collector. The optimal heat dissipation is sufficient Cooling the photovoltaic cells with the highest possible power generation. A ver deterioration in efficiency in this phase due to excessive collector temperatures is avoided.

Statt eines permanenten Parallelbetriebs, wie er bisherigen Hybridkollektoren vorgesehen ist, ergeben sich somit zwei mögliche Betriebsarten, und zwar auf der einen Seite eine be­ vorzugte Wärmenutzung bei vollem Modulationsgrad der Umwälzpumpe und auf der ande­ ren Seite eine bevorzugte Stromerzeugung bei einer Leistungsregelung der Umwälzpumpe im oberen Leistungsbereich. Als Kriterium für diese oder jene Optimierung gilt dabei das Wärmeangebot infolge der solaren Strahlung. Ist dieses gering, etwa während des Winter­ halbjahres, dann empfiehlt sich eine Optimierung der thermischen Nutzung. Ist dieses je­ doch höher, etwa während des Sommerhalbjahres, dann empfiehlt sich hingegen eine Op­ timierung der elektrischen Nutzung. Somit wird man geringeren Außentemperaturen die thermische Optimierung mit einer Anwendung des kompletten Modulationsbereichs und bei höheren Außentemperaturen die elektrische Optimierung mit einer Anwendung nur des oberen Modulationsbereichs vorsehen. Instead of permanent parallel operation, as provided by previous hybrid collectors is, there are thus two possible operating modes, namely a be on one side preferred use of heat with full degree of modulation of the circulation pump and on the other Ren side a preferred power generation with a power control of the circulation pump in the upper performance range. This is the criterion for this or that optimization Heat supply due to solar radiation. Is this low, for example during winter half-year, then an optimization of the thermal use is recommended. Is this ever but higher, for example during the summer half-year, an op is recommended timing of electrical use. So you will have lower outside temperatures thermal optimization with an application of the complete modulation range and at higher outside temperatures the electrical optimization with an application of only the Provide upper modulation range.  

Die Umschaltung von dem einen auf den anderen Optimierungsbereich kann in Abhängig­ keit von gemessenen Werten des Energieangebotes anhand der Außentemperatur und gegebenenfalls auch der solaren Strahlung erfolgen. Es ist auch eine Umschaltung in Ab­ hängigkeit von der jeweiligen Jahreszeit an je einem Stichtag im Frühjahr und im Herbst möglich.Switching from one to the other optimization area can be dependent of measured values of the energy supply based on the outside temperature and optionally also the solar radiation. It is also a switch to Ab Dependency on the respective season on a key date in spring and autumn possible.

Die Umschaltung sowie die Steuerung selbst kann in ein Energiemanagement für die Anla­ ge mit dem Hybridkollektor integriert werden. Die Sensorik für die Steuerung steht dabei mit dem Photovoltaik-Sensor bereits zur Verfügung, so dass keine Erweiterungen der bis­ herigen Vorrichtung nötig ist. Durch die erfindungsgemäße Programmierung wird das vor­ handene Energiepotential optimal genutzt.The switching as well as the control itself can be done in an energy management system be integrated with the hybrid collector. The sensors for the control are there with the photovoltaic sensor already available, so no extensions of the up previous device is necessary. The programming according to the invention makes this possible existing energy potential optimally used.

Die Zeichnung stellt in einer einzigen Figur das Schema einer Solaranlage als Ausfüh­ rungsbeispiel der Erfindung dar.The drawing shows the diagram of a solar system as a version in a single figure Example of the invention.

Ein Hybridkollektor 1 besitzt einen von Wasser durchströmten Absorber 2 für die Nutzung der elektrischen Energie. Durch eine Umwälzpumpe 4 im Solarkreis 5 wird das Wasser einem Wärmetauscher 6 im Solarspeicher 7 zugeführt. Die Umwälzpumpe 4 wird über ein Steuergerät 8 in Abhängigkeit von Messwerten an einem Außentemperaturfühler 9 und einem Speichertemperaturfühler 10 oder von sonstigen geeigneten Größen gesteuert.A hybrid collector 1 has an absorber 2 through which water flows for the use of the electrical energy. The water is supplied to a heat exchanger 6 in the solar storage 7 by a circulation pump 4 in the solar circuit 5 . The circulating pump 4 is controlled via a control unit 8 as a function of measured values on an outside temperature sensor 9 and a storage tank temperature sensor 10 or on other suitable variables.

Für die Optimierung der thermischen Nutzung wird die Umwälzpumpe 4 in einem Modulati­ onsbereich von beispielsweise 50 bis 100% variabel in ihrer Leistung geregelt. Dadurch passt sich der geförderte Volumenstrom des Solarwassers dem Wärmeangebot am Kol­ lektor an. Es wird ein Maximum an thermischer Energie dem Solarspeicher 7 zugeführt. Das ist speziell bei niedrigen Außentemperaturen, etwa im Winterhalbjahr, sinnvoll.To optimize thermal use, the circulation pump 4 is variably regulated in its output in a modulation range of, for example, 50 to 100%. This means that the volume flow of the solar water that is conveyed adapts to the heat available at the collector. A maximum of thermal energy is supplied to the solar storage 7 . This is particularly useful when the outside temperature is low, for example in the winter half-year.

Bei höheren Außentemperaturen, etwa im Sommerhalbjahr, empfiehlt es sich hingegen, die Umwälzpumpe 4 nur im oberen Modulationsbereich zu regeln. Niedrige Volumenströme mit einem Temperaturanstieg am Kollektor werden vermieden. Die gute Kühlung fördert den Wirkungsgrad der Photovoltaikzellen 3 und optimiert dadurch die elektrische Nutzung. In the case of higher outside temperatures, for example in the summer half-year, it is advisable to regulate the circulation pump 4 only in the upper modulation range. Low volume flows with an increase in temperature at the collector are avoided. The good cooling promotes the efficiency of the photovoltaic cells 3 and thereby optimizes the electrical use.

In beiden Phasen sind beide Nutzungsarten wirksam. Jede Nutzungsart ist zu ihrer Zeit jedoch optimiert, so dass ein Höchstmaß an thermischer und elektrischer Energie gewon­ nen werden kann.Both types of use are effective in both phases. Each type of use is in its time however, optimized so that a maximum amount of thermal and electrical energy won can be.
