Exergetic Analysis of a Solar-Powered Fish Dryer

Article Preview

Abstract:

To assess the efficiency and performance of a solar-powered fish drying system, a comprehensive exergetic analysis was conducted. The system was developed to enhance fish preservation in coastal and inland communities using renewable energy. The study evaluates the dryer’s thermodynamic behaviour based on the second law of thermodynamics, identifying energy losses and optimization opportunities. Key parameters such as solar irradiance, thermal energy, exergy destruction, and exergetic efficiency were analyzed. Results revealed that the solar-powered dryer achieved a maximum thermal and exergetic efficiencies of 72% and 54% respectively, demonstrating sustainability and viability for off-grid applications. The analysis supports the system’s potential for energy optimization and food preservation in low-resource settings.
