Abstract

The flow of water through a solar heating panel (1) is controlled by sensors on the inlet (6) and outlets (5) pipes. A temp. difference over the preset value energises a pump (3), causing water to flow into the heat storage tank (2). When the water in the panel has transferred its heat and cooled sufficiently the pump stops. The sensors are insulated from the ambient temp., only detecting the heat in the pipes, and the control unit (4) can be programmed to ensure a gradual start-up of the pump. To prevent overheating, the lower temp. sensor stops the pump if its water temp. becomes too high.

Description

Steuerung für SonnenkollektoranlagenControl for solar collector systems

Die Erfindung betrifft eine Steuerung für Sonnenkollektoranlagen, welche zur ontimalen Nutzung der Sonnenenergie dient und auch in vorhandene Anlagen nachträglich eingehaut werden kann.The invention relates to a control for solar collector systems, which is used for the ontimal use of solar energy and also in existing systems can be subsequently built in.

ner Gegenstand der Erfindung ist in der Zeichnung schematisch dargestellt. Es wird anhand seiner Funktion beschrieben.ner object of the invention is shown schematically in the drawing. It is described based on its function.

Dem Gerät sind zwei Thermofühler beigenackt. Ein Fühler 5 tiird am Sonnenkollektor 1 an der Wasseraustrittsseite unmittelbar am Anschlußrohr angeklemmt und gut gegen Wärmeeinflüsse isoliort.Two thermal sensors are included with the device. A feeler 5 is on Solar collector 1 clamped directly to the connection pipe on the water outlet side and well insulated against heat influences.

Den zweiten Fiihler 6 befestigen wir in ähnlicher Weise an der Wasseraustrittsseite des Wärmespeichers 2 an der Leitung, die zum Sonnenkollektor 1 fahrt (bei Schwimmbadheizung hnlich).We attach the second filter 6 in a similar way to the water outlet side of the heat storage tank 2 on the line that goes to the solar collector 1 (for swimming pool heating similar).

Steigt nun durch Sonneneinstrahlung die Temperatur am Fühler 5 über die des Fehlers 6, schaltet das Solarsteuergerät 4 den Pumpenmotor 3 ein und das wärmere Kollektorwasser heizt den Speicher 2 auf. Die Temperaturdifferenz, bei der das Steuergert schalten soll, ist am Steuergerät 4 einstellhar.If the temperature at sensor 5 rises due to solar radiation that of error 6, the solar control unit 4 switches on the pump motor 3 and that Warmer collector water heats storage tank 2. The temperature difference at which the control unit is to switch is adjustable on the control unit 4.

Sinkt die Temperatur des Fühlers 5 unter die Temperatur des Fühlers 6 nlus der eingestellten Temneraturdifferenz, schaltet das Steuergerät 4 wieder ab.If the temperature of the sensor 5 falls below the temperature of the sensor 6 nlus the set temperature difference, the control unit 4 switches again away.

Um eine Überhitzung des Speichers 2 bzw. des Schwimmbeckens zu vermeiden, hat das Solarsteuergerät 4 ein Temperaturüberwachglied eingebaut. Dieses schaltet den Pumpenmotor 3 sofort ah, wenn der Fühler 6 die Grenztemperatur Überschreitet.To avoid overheating of the tank 2 or the swimming pool, the solar control unit 4 has installed a temperature monitoring element. This switches the pump motor 3 immediately ah when the sensor 6 exceeds the limit temperature.

Die Proportionalschaltung des Gerätes ermöglicht es, in den Grenzbereichen der Temperaturdifferenz zwischen Fühler 5 und Fühler 6 mit gutem Wirkungsgrad Energie zu gewinnen.The proportional switching of the device makes it possible in the limit areas the temperature difference between sensor 5 and sensor 6 with good energy efficiency to win.

Das Drinzip besteht darin, hei Erreichen der eingestellten Temneraturdifferenz die Fhrdernumne 3 nicht sofort mit voller Leistung laufen zu lassen, sondern die Förderleistung durch Änderung der Pumpendrehzahl dem Bedarf anzupassen. Das heißt, daß bei Erreichen der eingestellten Temperaturdifferenz die Pumpe gleitend zu fordern beginnt (und umgekehrt). Die volle "umpenleistung ist erst nach weiteren 20C erreicht.The principle consists in reaching the set temperature difference not to let the leader number 3 run at full power immediately, but the Adapt delivery rate to requirements by changing the pump speed. This means, that when the set temperature difference is reached, the pump has to be called slidingly begins (and vice versa). The full power output is only reached after a further 20C.
