چکیده مقاله
This study presents a thermodynamic analysis of a single effect solar absorption refrigeration system operating under Dezful's climatic conditions 1800 2200 kWh/m² annual solar irradiance Using Engineering Equation Solver EES software, the system, comprising flat plate solar collectors, a LiBr H2O absorption chiller, a storage tank, and heat exchangers, was modeled to evaluate steady state performance The analysis focuses on mass, energy, exergy, and entropy balances across key components generator, condenser, evaporator, absorber Input parameters include generator temperature 90°C , condenser and absorber temperatures 35°C , evaporator temperature 5°C , and cooling load 65 kW , as specified in the reference conditions Results indicate a coefficient of performance COP of approximately 0 77, with the generator contributing the highest entropy generation 25% of total and exergy destruction 30% of total The system demonstrates potential for sustainable cooling in high irradiance regions, reducing fossil fuel dependency by up to 40% Sensitivity analysis highlights the significant impact of generator temperature on COP and entropy This study underscores the thermodynamic viability of solar driven refrigeration in Dezful, offering insights for sustainable cooling applications in similar climates
