The intention of the invention is to improve the cost-performance ratio of solar absorption systems, to increase their range of applications and to ensure that they can be fitted to a roof in a visually appropriate way with the minimum degree of expenditure. In order to achieve these aims, it is proposed according to the invention that the collector system be formed of transparent double-hose elements. The heat absorption is effected by means of a suitable strip-shaped absorption element which is inserted into the hose and divides the hose into an upper and a lower channel, a connection being formed between the channels at one end of the hose. The heat which is produced in the middle of the hose is conducted away by a transparent heat-transporting medium which flows through the hose according to the counterflow principle (Fig. 2). In order to increase the range of applications of the solar system, the absorption element can be coated on its upper side with photo-sensitive cells, as a result of which a combined generation of heat and electrical current is possible. Since the flexible hose elements are easy to mount they are highly suitable for retrofitting. |
