Countercurrent broken-glass solar collector

摘要

Technical problem of the invention. The energy losses due to heat conduction, convection and heat radiation on the side of the solar collector facing the sun are to be kept down. The collector is to be inexpensive. Solution of the technical object. The solution is characterised by the construction of the collector in three layers, at the top a plurality of layers of broken glass, thereunder a layer with a relative flow resistance and at the bottom a layer with a low flow resistance. The heated air is sucked off at the bottom, and at the top ambient air flows into the countercurrent broken-glass solar collector. By using broken glass as an essential component, the countercurrent broken-glass solar collector is very cheap. Area of applicaton. Heating of air of ambient temperature to a considerably higher temperature. <IMAGE>
