Title
Solarkollektor mit Kuehlfunktion
Other Title
Flat solar collector for cooling office building, has cooling channel allowing flow of heat transfer fluid, such that heat from heat transfer fluid is transferred to outer surface of transparent cover
Abstract
(A1) Die Erfindung betrifft einen Solarkollektor mit einer fuer Solarstrahlung weitgehend transparenten Abdeckung (5), welche eine Aussenflaeche (11) aufweist, einem Absorber (1), der ausgebildet ist einfallende Solarstrahlung in Waerme umzuwandeln, und einer ersten von einem ersten Waermetraegerfluid durchstroembaren Einrichtung (2) zur Abfuhr der durch Solarstrahlung gewonnenen Waerme. Der Kollektor zeichnet sich dadurch aus, dass eine zweite von einem zweiten Waermetraegerfluid durchstroembare Einrichtung (8) vorhanden ist, die derart ausgebildet ist, dass Waerme aus dem zweiten Waermetraegerfluid ueber die Aussenflaeche (11) uebertragen werden kann.

DE 102008053192 A1 UPAB: 20100506 NOVELTY - The collector has a transparent cover (5) with an absorber (1) to convert incident solar radiation into heat, and a meander shaped tube (2) for flowing of a heat transfer fluid e.g. liquid, for removal of the heat. A cooling channel (8) allows flow of another heat transfer fluid, such that the heat from the latter heat transfer fluid is transferred to an outer surface (11) of the transparent cover. The cover exhibits a cover element (6) that is made of glass and spaced apart from another cover element (7), where the cooling channel is formed by a gap formed between the cover elements. USE - Flat solar collector for cooling an office building. ADVANTAGE - The cooling channel is formed by the gap formed between the cover elements, such that dissipation of heat from the absorber to the environment is prevented, thus avoiding calorific losses during night, hence forming high-efficient solar collector.
