Abstract: | An experimental analysis of dual‐purpose corrugated plate solar collector (DPCPSC) is used to heat water and air simultaneously. Three types of corrugated plate solar collectors (CPSCs) were presented: namely single purpose corrugated plate solar collector (SPCPSC), only water heating of aluminum absorber plate (SPCPSC 1) and copper absorber plate (SPCPSC 2) and DPCPSC type water‐air compound heating of aluminum based absorber plate. In this experimental investigation, the comparative analysis of SPCPSC 1 and 2 at mass flow rate (MFR) of water was 0.025 kg/s (case 1 and 2) and 0.04167 kg/s (case 3 and 4), DPCPSC at MFR of air was 0.011 kg/s while MFR of water was 0.025 kg/s (case 5) and 0.04167 kg/s (case 6), respectively, and DPCPSC at MFR of water and air were 0.04167 and 0.023 kg/s, respectively (case 7), are analyzed. The results indicate that the efficiency of the DPCPSC, of case 6 is 16.74% higher than single purpose system that of case 3 and 6.65% also that of case 4. Comparing the DPCPSC, the optimum efficiency of case 7 is 8.64% higher than case 5 and 1.87% also higher than case 6. |
