Embodiment Construction

[0020]Referring to FIG. 1, the inflatable solar collector 1 has a cylindrical tube 2 as a sleeve. The tube is transparent, at least above a reflector membrane 5 which divides the tube 2 into two chambers 3, 4. In the illustrated example, the reflector membrane 5 is reflective on the top, upwardly facing side and extends essentially diametrically across the tube over the entire length of tube 2. An elongated absorber 6 is situated above the reflector membrane 5, approximately in the region of the lateral surface of the tube 2. This may be, for example, a pipe through which media flow. The chambers 3, 4 and the absorber 6 are connected to corresponding connecting lines 7, 8, 9. Two ballast chambers 10 are situated below the reflector membrane, and may be filled or emptied through lines 11 as needed. As shown in FIG. 1, the ballast chambers may be further divided into subchambers 18 which are connected via lines. Anchoring bands 12 are fastened at diametrically opposed outer sides of t...

Abstract

The invention relates to an inflatable solar collector (1) comprising an at least partially transparent sleeve divided at least into two chambers (3, 4) which are separated by a reflector membrane (5) reflecting on one side and which can respectively receive a gas, and at least one absorber (6) arranged opposite the reflective side of each reflector membrane (5). The sleeve is a cylindrical tube (2) and each reflector membrane (5) extends along the length thereof. The absorber(s) (6) is/are arranged along at least one focus line extending along the length thereof. Fillable ballast chambers (10) can be provided beneath the reflector membrane (5). Anchoring strips (12) are used for anchoring and bearing rolls (13) for support.

Description

RELATED APPLICATIONS[0001]This application claims the priorities of Austrian Patent Applications Nos. AT 505,075 B1 and AT 504,916 B1 and of PCT Application No. PCT / AT2008 / 000177, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention relates to an inflatable solar collector with an at least partially transparent sleeve divided into at least two chambers which are separated by a reflector membrane that is reflective on one side, and which can be independently acted on by a gas, and has at least one absorber that is oppositely situated from the reflective side of each reflector membrane.[0003]Such a spherical inflatable solar collector, which may be used for terrestrial energy production, has become known from a research report. All solar collectors of this type are based on the principle that solar radiation is bundled by the reflector membrane and directed to the absorber, which converts the solar radiation into energy. As the r...
