The goal of this project is to find out the optimum Spacing (Air Gap) of Glazing covers; of Single, Double and Triple Glazed Black painted Flat Plate Collector (FPC) and hence to find out the optimum combination of Number of Glazing and Spacing of Glazing covers(Air Gap) with minimum Top Heat Loss. For that purpose, three ‘one factor at a time’ experiments were designed for Single, double and triple Glazed FPC, taking Spacing of Glazing cover as variable factor having three levels (5 mm, 10 mm and 15 mm). In the second and third experiment, at each trial condition all the Spacing were kept equal to reduce number of experiment. In total nine prototypes (three for each experiment) were made and experimented simultaneously to cancel out natural variations. All the nine prototypes were exposed to sunlight at the same time and after one hour, stagnation temperature of the prototypes were recorded. The experiments were repeated for seven days. ANOVA for all three experiments were conducted to test the significance of the factor considered in the different cases. The result shows Double Glazed Flat Plate collector with 10 mm Air Gap is the optimal combination for a black painted absorber.
