Collector with integrated expansion machine, generator for converting thermal solar radiation into electricity has internal heat sink, uses carbon dioxide as heat carrying medium in several circuits

摘要

The collector has an integrated expansion machine (4), a generator (5) for converting thermal solar radiation into electricity and an internal heat sink. The device has several circuits and uses carbon dioxide or a hydrocarbon as the heat carrying medium in the circuits. The expansion machine is in the form of a turbine. A vacuum is at least partly caused by the heat carrying medium vapor jet.
