This study presents an energy and exergy analysis of R134A, R290, and R32 refrigerants in a vapor compression cycle to assess their environmental impacts and system performances. Factors such as the Coefficient of Performance (COP), exergy loss, exergetic efficiency, and deficiencies in system efficiency are considered. The analysis compares the refrigerants Ozone Depletion Potential (ODP) and Global Warming Potential (GWP), aiming to provide a comprehensive understanding of their performances.
The study finds R290 to be a more suitable alternative to R134A than R32, showing higher exergetic efficiency and lower efficiency defects at condenser temperatures between 40°C and 55°C. The analytical framework employed in this study is constructed utilizing the Engineering Equation Solver (EES) software. This study offers an accurate assessment of the refrigerants environmental impacts while considering their effect on system performance.
