Solarkollektor mit VerlustreduzierungSolar collector with loss reduction
Sonnenkollektoren üblicher Bauart bestehen aus einem beschichtetem Absorber, der in einem wärmegedämmten Gehäuse eingebettet ist und eine Abdeckung aus Glas und/oder Kuststoff aufweist.Solar collectors of conventional design consist of a coated absorber, which is embedded in a thermally insulated housing and has a cover made of glass and/or plastic.
Die bei besonders großen Temperaturunterschieden Kollektor-Außenluft entstehenden Wärmeverluste durch die Abdeckung können zwar durch mehrfach-Abdeckungen gemindert werden,aber sinkt dadurch auch die Transmission,was besonders bei geringer Einstrahlung zu großen Nachteilen führt.Durch die Kombination von transparenter Wärmedämmung und Glasplatte als Abdeckung konnten die Wärmeverluste bei Sonnenkollektoren wesentlich verringert werden.Da jedoch bei hoher energetischen Einstrahlung und Stillstand des Kollektors (Ausfall der Umwälzpumpe o.a.) Temperaturen über 200 Grad Celcius entstehen können,besteht die Gefahr,daß die Materialien des Kollektors,insbesondere die aus Kunststoffen bestehende transparente Wärmedämmung zerstört oder zumindest langfristig beschädigt oder in ihrer Funktion beeinträchtigt werden.The heat losses caused by the cover when there are particularly large differences in temperature between the collector and the outside air can be reduced by using multiple covers, but this also reduces the transmission, which leads to major disadvantages, especially when the radiation is low. The combination of transparent thermal insulation and a glass plate as a cover has made it possible to significantly reduce the heat losses in solar collectors. However, since temperatures of over 200 degrees Celsius can occur when there is high energy radiation and the collector is not working (circulation pump failure, etc.), there is a risk that the materials of the collector, in particular the transparent thermal insulation made of plastic, will be destroyed or at least damaged in the long term or their function will be impaired.
Der im Schutzanspruch 1. angegebenen Erfindung liegt das Problem zugrunde,einen Sonnenkollektor zu schaffender mit einem Überhitzungsschutz ausgestattet bei auftreten von hohen,dem Kollektor schadenden Temperaturen eine Kühlung unterhalb der kritischen Temperatur der wärmeempfindlichen Kollektormaterialien bewirkt.The invention specified in claim 1 is based on the problem of creating a solar collector which is equipped with an overheating protection and which, when high temperatures occur which are damaging to the collector, causes cooling below the critical temperature of the heat-sensitive collector materials.
Dieses Problem wird mit den im Schutzanspruch 1. aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.
Mit der Erfindung wird erreicht,daß beim Auftreten von hohen den Kollektormaterialien schadenden Temperaturen eine automatische Kühlung durch temperaturgesteuerte Lüfter zur Be- und Entlüftung einsetzen und dadurch den Solarkollektor vor Überhitzung und somit vor Zerstörung,Beschädigung oder Beeinträchtigung der Kollektormaterialien schützen.Außerdem wird durch abführen der Feuchte die Transmission der transparenten Abdeckung und die feuchteempfindliche selektive Beschichtung des Absorbers (4) nicht mehr beeinträchtigtes zusammenfassend einen langjährigen verlustarmen betrieb des Solarkollektors bedeutetThe invention ensures that when high temperatures occur that are damaging to the collector materials, automatic cooling is used by temperature-controlled fans for ventilation and thus protecting the solar collector from overheating and thus from destruction, damage or impairment of the collector materials. In addition, by removing the moisture, the transmission of the transparent cover and the moisture-sensitive selective coating of the absorber (4) are no longer impaired, which in summary means that the solar collector can operate for many years with low losses.
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2. gegeben. Da bei Sonnenkollektoren-Gehäuse(l) ein absolute Dichtigkeit meist nicht erreicht wird,kann es insbesonders in den Morgenstunden zum beschlagen der Abdeckungsinnenfläche und dadurch zur verminderter Transmission der transparenten Abdeckung kommen. Wird am Feuchte-Sensor(7) der unmittelbar unter der Abdeckungsinnenfläche(6) installiert ist der eingestellte Wert der Feuchte-Regelung(lO) überschritten,werden Lüfter zum befreien der Abdeckungsinnenfläche von der Kondensationsfeuchte eingeschaltet.An advantageous embodiment of the invention is given in claim 2. Since absolute tightness is usually not achieved with solar collector housings (1), the inner surface of the cover can fog up, particularly in the morning hours, and this can lead to reduced transmission of the transparent cover. If the set value of the humidity control (10) is exceeded on the humidity sensor (7) installed directly under the inner surface of the cover (6), fans are switched on to free the inner surface of the cover from condensation moisture.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutertAn embodiment of the invention is explained with reference to the drawing
Erhitzt sich der Kollektor auf eine die den Kollektor-Materialien( insbesondere
der transparenten Wärmedämmung 5) kritischen Temperatur,wird durch den Temperatursensor (11) und der eingestellten Temperatur an der elektrischen
Lüftersteuerung (10),Lüfter zur Be-und Entlüftung des Kollektorinnenraumes eingeschaltet,was eine Öffnung der Lüfterklappen (13) bewirkt und eine
Überhitzung der Kollektormaterialien verhindert.If the collector heats up to a temperature that is critical for the collector materials (in particular the transparent thermal insulation 5), the temperature sensor (11) and the set temperature on the electric fan control (10) switch on the fan to ventilate the interior of the collector, which causes the fan flaps (13) to open and
Prevents overheating of the collector materials.
