Solar-energy converter

Abstract: A solar energy converter which can be used as a solar collector or for the direct mounting on a building for the heating of the interior thereof through a wall of the building has a light transmissive layer spaced from this wall and provided on its inner side with an absorptive surface at which incident solar energy is transformed into heat. One or more solar structures between this layer and the wall contain a chemico-physical phase transformation medium capable of storing latent heat when thermal energy is produced at the absorptive surface and adapted to release this heat through the wall or to a heat carrier fluid which can be passed through a space formed by the solar structure.

Wall for the absorption of sun rays

Abstract: 1. Wall having an external layer (4) which is secured approximately parallel thereto on the front external face, which is permeable to solar rays and behind which there is arranged at a distance a surface (2, 2_a) absorbing solar radiation, there being arranged in the cavity between this external layer (4) and the absorbing surfaces (2, 2_a) translucent, heat-insulating material, characterised in that the translucent, heat-insulating material consists of acrylic glass or silgel in the form of foam or capillary tubes or in amorphous form.

Solar collector with a layer fixed on the outer side

Abstract: Die Erfindung betrifft einen Sonnenkollektor mit einer auf der Ausenseite davor parallel befestigten, den Sonnenstrahlen ausgesetzten Schicht zur Absorption der Sonnenstrahlungsenergie. Zumindest die auserste Schicht (6) ist lichtdurchlassig, und zwischen der ausersten Schicht (6) und der Innenwand (1) oder der Kollektorinnenseite ist mindestens eine Sonnenstrahlen absorbierende Flache (9) angeordnet, an der mindestens ein mit Salzhydrat reziproken Salzpaaren oder einer Mischung aus Salzhydrat und Salz gefullter Raum (4) angrenzt.
