Abstract
In this study, an absorption refrigeration cycle with the working fluid of water-lithium bromide is considered. The needful energy for generator is supplied by the steam at 100°C and in one atmospheric pressure. The exergy analysis is conducted on the whole cycle and it is calculated based on the first and the second laws of thermodynamics. Various components are compared in terms of thermodynamic efficiency. Finally the coefficient of the mentioned cycle is obtained. According to the simulation results, the highest rate of exergy destruction is in the absorber, and it is equal to 35.87 % of the destruction and the main cause of this irreversibility is heat transfer with the high-temperature difference. To improve this, we should increase heat exchange and then reduce the temperature difference. For the system performance improvement, particular attention should be paid to this part to reduce the outlet exergy.
