Résumé

In this paper the results of the experimental testing of the double exposure flat-plate and the conventional flat-plate water solar collectors are presented. The double exposure flat-plate solar collector (DEFPC) is a solar collector which can absorb solar radiation by upper as well as lower absorber surface. Absorption from lower absorber surface is enabled by application of a flat-plate reflector. The reflector is placed in parallel below the collector. The experiments were performed in the months of August, September and October in 2012. In this paper the experimental results for the dates when the achieved daily irradiation of the lower absorber surface of the DEFPC was the lowest (8th of August) and the highest (4th of October) are presented. The results showed that the thermal power of the DEFPC was 41,79% to 66,44% higher than the thermal power of the conventional solar collector (FPC). The thermal efficiency of the DEFPC is the similar to that of the FPC. The daily average thermal efficiency of the DEFPC and the FPC during the 8th of August was 0,575 and 0,576, while during the 4th October 0,521 and 0,508, respectively.
