This paper presents a developed ecological function for absorption refrigerators with fourtemperature-level. Moreover, aforementioned absorption refrigerator is optimized by implementing ecological function. With the aim of the first and second laws of thermodynamics, an equivalent system is initially determined. To reach the addressed goal of this research, two objective functions: the coefficient of performance (COP ) and the ecological function (E) have been involved in optimization process simultaneously. The first aforementioned objective function has to maximize the rest objective functions, on the other hand, have to maximize in parallel optimization process. Developed multi objective evolutionary approaches (MOEAs) on the basis of NSGA-II method are implemented throughout this work.

“…1, the absorption refrigerator in the hybrid system is operated between three heat reservoirs with temperatures T, T c , and T 0 , and the temperatures of the cyclic working fluid in three isothermal processes are different from those of external heat reservoirs, where T 1 and T 2 are respectively the temperatures of the working fluid in the generator and evaporator, T 3 is the temperature of the working fluid in the condenser and absorber. According to the theory of non-equilibrium thermodynamics, the equations of the heat transfer between the working fluid and the heat reservoirs may be written as [36,37].…”

The new thermo-ecological performance optimization of absorption is investigated by taking the ecological coefficient of performance ECOP as an objective function. ECOP has been expressed in terms of the temperatures of the working fluid in the main components of the system. The maximum of ECOP and the corresponding optimal temperatures of the working fluid and other optimal performance design parameters such as coefficient of performance, specific cooling load of absorption refrigerators, specific heating load of absorption heat pumps, specific entropy generation rate and the distributions of the heat exchanger areas have been derived analytically. The obtained results may provide a general theoretical tool for the ecological design of absorption refrigerators and heat pumps.
