Patentbeschreibung_Patent description
"Zusammenfaltbare Vorrichtung zum Erhitzen von Wasser durch Sonneneinstrahlung"" Foldable device for heating water by solar radiation "
Warmwasser wird in vielen Industriezweigen und in den Haushalten tagtäglich benötigt. Die enormen Energiemengen, die zu seiner Aufbereitung nötig sind, könnten zumindest teilweise durch Solarenergie gedeckt werden. Es wäre durchaus sinnvoll, die"hochwertigen" Energierträger - wie z.B. Öl — vorwiegend zur Erzielung von Wassertemperaturen über 100 C zu benutzen und die "minderwertige" Energiequelle Sonne für den Temperaturbereich darunter. Voraussetzung hierzu sind Sonnenwarmwasserkollektoren, die als low-price Systeme in grossen Mengen ökonomisch herstellbar, leicht in bestehende Wasserkreisläufe zu integrieren und weitgehendst wartungsfrei sind. Ausserdem sollen sie gefaltet leicht transportierbar, sein.Hot water is used in many industries and in households needed every day. The enormous amounts of energy required for its processing could at least partially be covered by solar energy. It would make perfect sense to use the "high quality" Energy carriers - such as oil - are to be used primarily to achieve water temperatures above 100 C and the "inferior" energy source, the sun, for the temperature range below. The prerequisite for this are solar hot water collectors, which are easy to manufacture as low-price systems in large quantities can be integrated into existing water cycles and are largely maintenance-free. In addition, they should be easy to transport when folded, be.
Diese Bedingungen erfüllt die im Folgenden vorgeschlagene Vorrichtung zum Erhitzen von Wasser durch Sonneneinstrahlung, Sie ist ein klein zusammenfaltbares, leichtes, gut transportables System, das über geeignete Anschlüsse (6, 7) zum Anschluss an vorhandene Wasserkreisläufe verfügt. Es wird auf sonnenreichen Orten - wie z.B. Flachdächern - ausgelegt und durch den Wasserdruck im vorhandenen Wasserkreislauf zur Entfaltung gebracht. Im entfalteten Zustand ist die Einheit so schwer, dass sie statisch stabil,ζ.·Β. gegen Windeinflüsse, am Auslegeort liegen bleibt.The device proposed below fulfills these conditions for heating water by solar radiation, it is a small foldable, light, easy to transport System that has suitable connections (6, 7) for connection to existing water circuits. It will be sunny on Places - such as flat roofs - and made to unfold by the water pressure in the existing water cycle. When unfolded, the unit is so heavy that it is statically stable, ζ. · Β. against wind influences, remains at the place of deployment.

Sie nimmt die linsenartige Form eines Wassertropfens mit künstlicher Oberflächenspannung an.It takes the lenticular shape of a water drop with artificial Surface tension.
Das System besteht aus einer oder mehreren Einzeleinheiten, die beliebig kombinierbar miteinander verbunden werden können.The system consists of one or more individual units that can be combined with one another as required.
Erfindungsgemäss besteht eine Einheit aus einem geschlossenen Kunststoffsack (θ), dessen Bodenfläche [5) lichtabsorbierend, gut wärmeisolierend und mechanisch widerstandfähig sowie gegen Schädlingsfrass resistent ist (1O) und dessen Deckfläche (3) von einem Lichtfenster in Form einer klar durchsichtigen Kunststoffolie gebildet wird. Die Wärmeisolation zum Boden hin wird durch eine flexible Isolationsschicht (9) aus Luftbläschenfolie, die mit der absorbierenden Schicht direkt verbunden ist, gewährleistet.According to the invention, a unit consists of a closed one Plastic bag (θ), the bottom surface [5) of which is light-absorbing, has good thermal insulation and mechanical resistance and is resistant to pests (1O) and its top surface (3) is formed by a light window in the form of a clear, transparent plastic film. The thermal insulation to the floor is through a flexible insulation layer (9) made of air bubble film, which is directly connected to the absorbent layer, guaranteed.
Erfindungsgemäss ist die durchsichtige Deckschicht der Einheit (3) so konzipiert, dass sie entweder gut wärmeleitend mit der Umgebungsluft verbunden ist, oder aber von dieser wärmeisoliert ist. Dies wird dadurch erreicht, dass die durchsichtige Deck— folie aus zwei, an ihren Rändern luftdicht verbundenen Folienschichten (3,1) aufgebaut ist, zwischen die bei Bedarf ein Luftpolster (2) gebracht werden kann.According to the invention, the transparent cover layer of the unit (3) is designed so that it either conducts heat well with the Ambient air is connected, or is thermally insulated from this. This is achieved by the fact that the transparent cover- film is made up of two film layers (3,1) connected airtight at their edges, between which an air cushion if necessary (2) can be brought.
Bei Lufttemperaturen, die über der des erwärmten Wassers liegen, sind die zwei Schichten ohne Luftpolster wärmeleitend mit der Luft verbunden und können so zusätzlich zur direkten Sonneneinstrahlung Wärme durch Wärmeleitung dem Wasser zuführen. Ist die Lufttemperatur niedriger als die des erwärmten Wassers, wird ein Luftpolster (2) zwischen die beiden Schichten gebracht, welches eine ausgezeichnete Wärmeisolierung darstellt und einen Wärmeverlust des Wassers an die Umgebung verhindert.At air temperatures that are above that of the heated water, the two layers are connected to the air in a thermally conductive manner without air cushions and can thus be used in addition to direct sunlight Apply heat to the water by conduction. If the air temperature is lower than that of the heated water, a Air cushion (2) placed between the two layers, which is excellent thermal insulation and heat loss of the water to the environment.
Erfindungsgemäss sind Zu- und Ablauf (6, 7) jeder Einheit mit Drosselhähnen versehen. Hiermit können der Wasserdruckfluss (4) und die erreichbare Wassertemperatur gesteuert werden und eine gleichmässige Füllung der Heizelemente erreicht werden.According to the invention, the inlet and outlet (6, 7) of each unit are provided with throttle valves. This allows the water pressure flow (4) and the achievable water temperature can be controlled and an even filling of the heating elements can be achieved.

Heizungseinheiten, die auf abfallenden Hängen ausgebreitet werden sollen, erhalten erfindungsgemäss zusätzlich kammartig ineinandergreifende Schweissnähte (11), durch die das Wasser mäanderförmig hindurchfliesst und ein Wegrollen der Einheit verhindert. Die auf die Heizungseinheit auftreffende Sonnenenergie von max, 1 KW/m (Mittagszeit) durchdringt die durchsichtige Deckfolie (1, 3) und das Wasser (4) und wird von der dunklen Bodenfläche (5) absorbiert. Diese erwärmt sich und das über ihr fliessende Wasser (4). Die auf diese Weise geleistete Erwärmungsarbeit desAccording to the invention, heating units that are to be spread out on sloping slopes are additionally provided with comb-like interlocking ones Weld seams (11) through which the water meanders flows through it and prevents the unit from rolling away. The solar energy incident on the heating unit of max, 1 KW / m (lunchtime) penetrates the transparent cover sheet (1, 3) and the water (4) and is removed from the dark floor area (5) absorbed. This heats up and the water flowing over it (4). The heating work of the

Wassers entspricht pro m und Stunde dem Heizwert von ca. -rg 1Water corresponds to the calorific value of approx. -Rg 1 per m and hour
Erfindungsgemäss ist die Einheit mechanisch so stabil aufgebaut, dass sie auch als Sitz oder Liegekissen geeignet ist. Dies geschieht durch Auswahl geeigneter Folien hoher Festigkeit und eine optimale Schweisstechnik.According to the invention, the unit is so mechanically stable that it is also suitable as a seat or a bed cushion. this happens by selecting suitable high-strength foils and an optimal welding technique.
Grundsätzlich ist die beschriebene Vorrichtung zum Erhitzen von Wasser durch Sonneneinstrahlung überall dort einsetzbar, wo Sonne scheint und Warmwasser bis ca. 1QO C benötigt wird. Zur Speicherung der während der Sonnenperioden anfallenden Wärme sind Latentwärmespeicher mit paraffinähnlichen Stoffen vorgesehen.In principle, the device described for heating water by solar radiation can be used anywhere where where the sun shines and hot water up to approx. 1QO C is required. Latent heat stores with paraffin-like substances are provided to store the heat generated during the solar periods.
