Solar collector and compound glazing

摘要

The solar collector comprises a transparent covering and an absorber with a front side (102) and a rear side (103). The front side faces the solar radiation and the rear side is turned away from the solar radiation, where a medium is provided for reflecting the infra red radiation in the direction of the absorber. A rear wall is formed as a transparent disk, particularly a rear glass pane (3) or a plastic disk. Independent claims are also included for: (1) a composite panel, particularly a composite glass pane with a frame; and (2) an absorber with a heat exchanger medium.
