Solar energy is replacing more and more traditional sources of energy because\nof the fact that itâ??s also fighting about global warming. This study is based on\nexergy analysis of a double-effect series flow absorption refrigeration system\npowered by solar energy in Ngaoundere. The simulation is done on the basis\nof a half hourly analysis for the first time, from 6.30 AM to 6.30 PM, using\nwater-lithium bromide as working pair. The main parameters for the performance\nof an absorption cycle, which are the COP and the ECOP, have been\nanalyzed and the results show that this two parameters increase while increasing\nthe temperature of the main generator. The exergy loss of each\ncomponent of the system and the total exergy loss of the system have been\nanalyzed and their effectiveness calculated, using the first and second law of\nthermodynamics. The highest exergy loss occurs in the main generator GI\nand in the absorber, making these components more important in an absorption\ncycle. This analysis is based on a mathematical model using FORTRAN\nlanguage. The results obtained may be useful for the optimization of solar\nabsorption refrigeration systems.
