Solar-powered heating system uses air, as the heat carrier medium, with plastic components for the absorber and absorption/collection chambers for light weight and rapid response even in weak sunlight

摘要

Solar-powered heating system, using heated air as the heat carrier medium, has an absorber (3) of a perforated plastic film with an absorbency of at least 80% in the visible wavelength range. An absorption chamber (4), filled with gas through an inflow opening and which can be divided into compartments, is on one side of the absorber. The solar-powered heating system, using heated air as the heat carrier medium, has an absorber (3) of a perforated plastic film with an absorbency of at least 80% in the visible wavelength range. An absorption chamber (4), filled with gas through an inflow opening and which can be divided into compartments, is on one side of the absorber, with its wall away from the absorber formed by a transparent plastic film (2). A similar gas-filled collection chamber (5), with a gas outflow opening, is on the other side of the absorber with a back wall formed by at least one plastic film. A thermal insulation chamber (14), formed by a plastic film (8), has at least one opening for a gas inflow and gas outflow.
