experimental study of a solar air collector with doubles glazed

Our work focused on an experimental study of a double-glazed solar air collector in the biskra site. the main objective of our work was to minimize thermal losses forward. the experimental model used is based on addition of second glass and increase in distance between the two panes. the study was carried out for the comparison between the average absorber temperature, glass and the outlet temperature and the efficiency for the single-pane and double-pane solar air collector with variable distance (1, 2 and 3cm). correspond to the three flow rates used. experimental results showed that the addition of second pane is effective in minimizing forward thermal losses for a solar air collector. the obtained results from the experimental readings showed that the minimization of thermal losses forward is a very important factor for improving the performance of a solar collector. experimental results showed that the addition of second glazes is effective in minimizing forward thermal losses for a solar air collector.
