An efficient optimization of an irreversible Ericsson refrigeration cycle based on thermo-ecological criteria

• Thermo-ecological problem of Ericsson refrigeration cycle is developed and solved. Multi-objective optimization refrigerating investigated. Investigation the effect operating parameters on system performance. sensitivity design variables thermo-ecological objective. In present work, a multi-objective study an irreversible carried out to evaluate cryogenic refrigerator based thermal ecological The coefficient performance, cooling load input power are considered as objective functions along with function like effectiveness heat sink exchanger, source temperature ratio capacitance rate source. Objective optimized using transfer search algorithm for two different scenarios, Pareto front obtained. decision making method namely TOPSIS adopted identify best solution among numerous optimal solutions each scenario. explored presented. A maximum 3.27 kW at 172 K obtained 3.91 COP 0.84. Finally, distribution during identified
