Solar collector arrangement for use as e.g. facade element in facade of building, has disk element including recess i.e. hole, for single connection between chambers for gas pressure compensation between chambers
The arrangement (10) has two disk elements (12, 14) i.e. glass disks, defining an outwardly medium-tight sealed intermediate chamber (18). One of the two disk elements (14) and a third disk element (16) define an outwardly medium-tight sealed intermediate chamber (20). An absorber (22) is arranged in the former chamber. Endothermic fluid flows through the absorber. One of the two disk elements (14) includes a recess (52) i.e. hole, for single connection between the chambers for gas pressure compensation between the chambers. A cross-section of the recess is approximately 5 square mm.
