Experimental Investigation to Determine the Performance of Solar Thermal Collector with Single and Double Glazing

Abstract

The purpose of this study is to see the effect of using the double glazing on the performance of the thermal air solar collector with a single air pass without using fins under the absorbing plate have been investigated experimentally. The experimental work with the following conditions such as: volume flow rate (0.012 m3/s), an angle of inclination of the collector (30o). The experimental setup was realized at the mechanical workshop at the University of Laghouat, Algeria. This study shows the evolution of the thermal parameters of the solar air collector as function of the local solar time such as temperature of: the absorber, the bottom plate, the outlet air, and the thermal efficiency. The experiment has been carried out between 09.00 AM to 04.00 PM. The result shows that the efficiency of double glazing is slightly higher compared to single glazing.
