In this study, a modified reverse flow type, one of the triple effect absorption cycles, is studied for performance improvement. The cycle simulation is carried out by using EES(Engineering Equation Solver) program for the working fluid of H₂O/LiBr solution. The split-ratios of solution flow rate, UA of each component, pumping mass flow rate of solution are considered as key parameters. The results show that the optimal SRH (split ratio of high side) and SRL (split ratio of low side) values are 0.596 and 0.521, respectively. Under these conditions, the COP is maximized to 2.1. The optimal pumping mass flow rate is selected as 3 ㎏/s and the corresponding UAEVA is 121 ㎾/K in the present system. The present simulation results are compared to the other literature results from Kaita’s (2002) and Cho’s (1998) triple effect absorption systems. The present system has a lower solution temperature and a higher COP than the Kaita’s modified reverse flow, and it also gives a higher COP than the Cho’s parallel flow by adjusting split ratios.
