Energy, exergy, energy matrices, exergoeconomic, and enviroeconomic (5E) analysis of active solar distiller using water loaded nanoparticles: A comparative study

Abstract

The exergoeconomic and enviroeconomic analysis of a hybrid double slope solar distiller system using Al₂O₃ nanoparticles in a CPC collector was examined in the current work. MATLAB was used with input data of New Delhi climate conditions provided by IMD Pune, India for mathematical calculations. The yield was evaluated based on the energy seasonally outlet, with maximum yield being 16.44 kg/day, minimum yield being 5.25 kg/day, and annual yield being 8.52% higher. The average energy payback time was 16.16%, the average energy payback factor was 13.91%, and the average life cycle cost conversion efficiency was observed to be 7.15% higher. In terms of enviroeconomics, the proposed system has a carbon mitigation/ton of 57.45, carbon credit earnings of 287.29 ($), an annual exergy of 7.31%, and a productivity of 5.17%. Over a 20-year period at an interest rate of 3%, System-A has a calculated value of 0.083, while System-B has a calculated value of 0.080 for the Rex parameter in kWh/₹. Additionally, the proposed system has a 4% higher Rex value than System-B and a distillate cost of 1.52 (₹/kg). The proposed system has been found better than the existing method, and future research may examine the use of various nanoparticles.
