摘要

The hot air solar roof has two layers, one facing the sun that is transmissive and one that is absorbent to radiation, between which air is heated and fed by natural convection to a device that utilizes the heat. The two layers consist of roof tiles, the upper one of glass tiles and the lower one conventional tiles or radiation absorbing glass tiles.
