Thermodynamic and Exergy Analysis of Solar-Based Absorption Refrigeration cycle

The use of solar energy in the refrigeration cycle is one of the newest ways to increase the coefficient of performance and use of clean energy. The purpose of this paper is to present a parametric simulation and the performance analysis of a water- lithium bromide absorption refrigeration cycle equipped with a solar receiver in terms of thermodynamics and exergy.The effect of different parameters on system efficiency, heat transfer rate in generator, exergy efficiency and exergy changes of the whole system is investigated.The results of the study show that there is an optimal radiation intensity at a given temperature for the evaporator and condenser, in which the total exergy changes of the system are minimized and the system coefficient of performance and its exergy efficiency reach its maximum. The results show that when the evaporator temperature is in the range of 4 to 10 ° C and the condenser temperature is in the range of 33 to 39 ° C, the maximum yield coefficient for the single-cycle cycle is in the range of 0.75 0 to 80/0. Also, surveys show that the maximum exergy efficiency for a single-cycle refrigeration cycle is in the range of 13 to 23.7 percent.
