Abstract
Description
B e s c h r e i b u n g Description
Titel: Sonnenkollektor aus Kunststoffrohren Anwendungsgebiet: Die Erfindung betrifft einen Sonnenkolleltor aus Jtunststoffrohren, durch den Wasser fließt, das durch Sonnenenergie aufgeheizt wird. Das erwärmte Wasser kann bestehenden Heizungsanlagen zugeleitet werden.Title: Solar collector made of plastic pipes Area of application: The The invention relates to a solar panel door made of plastic pipes through which water flows that is heated by solar energy. The heated water can be existing Heating systems are fed.
Zweck: Durch die Gewinnung von Warmwasser aus Sonnenenergie sollen die herkömmlichen Energieträger wie Erdöl, Gas, Kohle u.a. entlastet und auf längere Sicht eine Kostenminderung erzielt werden. Gleichzeitig wird auch die Verschmutzung infolge Ruß- und Ab gas entwicklung herabgesetzt.Purpose: The aim is to obtain hot water from solar energy the conventional energy sources such as crude oil, gas, coal, etc. relieved and for a longer period of time A cost reduction can be achieved. At the same time there is also pollution reduced as a result of soot and exhaust gas development.
Stand der Technik mit Fundstellen: Die Erkenntnis, Sonnenstrahlen durch dunkle Stoffe zu absorbieren um damit Wasser aufzuheizefis-rird schon seit längerem praktisch nutzbar gemacht ( siehe auch die Broschüre " Solarenergie heute ", herausgegeben von der Firma Walter Zink in Nürtingen).State of the art with sites of discovery: The knowledge, sun rays to absorb through dark fabrics in order to heat up water has been around for a long time Made practically usable for a longer period of time (see also the brochure "Solar Energy Today ", published by Walter Zink in Nürtingen).
Kritik des Standes der Technik: Der Bauaufwand und die davon abhängenden Herstellungskosten sind beträchtlich und oft bereitet auch die anzustrebende senkrecht zum Strahleneinfall aufzustellende Kollektorfläche weitere aufwendige Maßnahmen.Criticism of the state of the art: The construction costs and the ones that depend on it Manufacturing costs are considerable and often the desired vertical one also prepares Collector surface to be set up for incidence of radiation, further elaborate measures.
Aufgabe: Das Ziel der Erfindung ist, die Herstellungskosten von Sonnenkollektoren wesentlich zu vermindern, die Montage zu vereinfachen, Materialien auszuwählen, die den Wirkungsgrad verbessern und einen günstigen Strahleneinfallswinkel zu erzielen.Task: The aim of the invention is to reduce the manufacturing costs of solar panels to reduce significantly, to simplify assembly, to select materials, which improve the efficiency and achieve a favorable angle of incidence of the rays.
Lösung: Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß der Sonnenkollektor aus einem verhältnismäßig billigem doppeltem Kunststoffrohr besteht und in einfacher Weise auf einem Hausdach montiert werden kann.Solution: This object is achieved according to the invention in that the Solar collector consists of a relatively cheap double plastic tube and can be easily mounted on a house roof.
Weitere Ausgestal- Um den Wasserdurchfluß ohne zusätzlichen Energietung der Erfindung: aufwand aufrecht zu erhalten, wird der Sonnenkollektor mit einem Druckminderungsventil an die Trinkwasserleitung angeschlossen. Die Durchflußgeschwindigkeit regelt ein Dosierventil am Auslauf des Kollektors.Further designs around the water flow without additional energy the invention: effort to maintain is the solar collector connected to the drinking water pipe with a pressure reducing valve. The flow rate regulates a metering valve at the collector outlet.
Erzielbare Vorteile: Die Herstellung des doppelten t.unststoffrohres kann fabrikmäßig ait Hilfe einer Strangpresse vorgenommen werden. Das nststoffrohr ist biegsam und kann daher in Schneckenform mit einfachen Halterungen am Dach befestigt werden. Der Sonnenstrahleneinfallswinkel ist bei allen Sonnenstellungen, infolge des runden Rohrquerschnittes, immer senkrecht zu einem Rohrdurchmesser. Durch den Anschluß an die Trinkwasserversorgung wird eine Umwälzpumpe eingespart.Achievable advantages: The production of the double plastic pipe can be done at the factory using an extrusion press. The plastic pipe is flexible and can therefore be attached to the roof in a snail shape with simple brackets will. The angle of incidence of the sun's rays is a result of all sun positions of the round pipe cross-section, always perpendicular to a pipe diameter. Through the There is no need for a circulation pump connected to the drinking water supply.
Beschreibung eines Ausführungsbeispieles: Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die obere Abbildung zeigt unmaßstäblich den in Schneckenform verlegten , 300m langen,Kollektor.Description of an exemplary embodiment: An exemplary embodiment the invention is illustrated in the drawing and will be described in more detail below. The picture above shows, not to scale, the 300m long collector laid in a spiral shape.
Unten ist ein Querschnitt des doppelten Kunststoffrohres dargestellt.A cross-section of the double plastic pipe is shown below.
Wirkungsweise: Aus der Trinkwasserleitung fließt das Wasser über einen Zähler zum Druckminderungsventil, worin der Wasserdruck soweit herabgesetzt wird, daß alle Gesamtwiderstände überwunden werden. Während des Durchflusses absorbiert das Wasser Sonnenenergie und erwärmt sich.How it works: The water flows over you from the drinking water pipe Counter for the pressure reducing valve, in which the water pressure is reduced so far, that all total resistances are overcome. Absorbed during flow the water solar energy and heats up.
Das erwärmte Wasser fließt mit einer errechneten konstanten Geschwindigkeit, geregelt vom Dosierventil, zu einem Warmwasserspeicher.The heated water flows at a calculated constant speed, regulated by the metering valve, to a hot water storage tank.
