Abstract


The present work presents an experimental study on the evolution of the temperatures of the various components making up a flat solar collector intended to produce hot air. To do this, it was deemed necessary to design and manufacture a new type of flat plate air solar collector equipped with cylindrical mini-concentrators with reflective mirrors (CMCRM). The temperatures were measured using type K thermocouples placed on the glazing, absorber, and in the air space between the absorber and glazing. The temperatures of ambient air and at the outlet of the solar collector were also measured. Several series of measurements were recorded during the day of April 13, 2023. Starting from an ambient air temperature of around 27 °C (inlet air temperature), it was found that the temperatures at the absorber and at the output of the solar collector could reach 139 °C and 129 °C, respectively, which represents an improvement of 30% compared to a conventional air solar collector. These results are considered as very encouraging.
