Experimental and theoretical investigation of thermal efficiency and productivity of single slope basin type solar distillation system using honey-comb

Abstract

The aim of current research was to improve water quality by constructing a single slope basin type solar water distillation system with honeycomb, as well as to increase distilled water pro-ductivity. In this investigation, honeycomb structure of 2.25 cm and a diameter of 6 mm in a square section (100 cm ×100 cm) have been proposed to enhance the efficiency of the solar still. An experimental analysis was done to investigate the performance of the honeycomb structure. Thermal efficiency of the standard solar distillation system was obtained approxi-mately 18.48%, while the thermal efficiency and productivity of the solar distillation system with honeycomb was obtained 25.45% and 749.58 ml/m2 respectively. It was concluded that, the solar distillation system with honeycomb structure was more efficient that a simple con-ventional solar distillation system. The addition of honeycomb structure in simple solar de-salination system increased the productivity and efficiency by 35.36% and 37.71% respectively.
