ENERGY AND EXERGY ANALYSİS OF A TRİPLE-EFFECT ABSORPTİON REFRİGERATİON SYSTEM BASED ON GENERATORS

KENAN SAKA,  İBRAHİM HALİL YILMAZ,  TAHA TUNA GÖKSU, 

 Today, even if the increasing energy security problem has brought about system designs having negative effects on the environment, the clean energy sustaining systems have come out the forefront. Absorption refrigeration systems are electricity saving systems, which reduce the electricity consumption to a minimum compared to vapor compression systems. These systems can be designed as half, single, double and triple effect to increase the performance. Increasing the number of effects increases the performance of absorption systems as well as the number of system components which leads to more complicated and precise systems to be controlled. In this study, the thermodynamic analysis of a triple effect series flow lithium bromide-water absorption refrigeration system was made using the Engineering Equation Solver (EES) program, and the obtained simulation results was verified with the literature. It was shown that energy and exergy coefficient of performance (COP and ECOP) increase with the increase of the low pressure generator temperature and decreases with the increase of the high pressure generator and medium pressure generator temperatures. The increase in the condenser and absorber temperatures was found to have an adverse effect on the COP.
