Abstract
This work presents exergy analysis of a double effect parallel flow, single effect and half effect absorption systems for comparison. A computer program is developed for the thermodynamic properties of lithium bromide - water solutions by the author in FORTRAN codes for the exergy analysis. The coefficient performance (COP) and the exergetic coefficient performance (ECOP) of the double effe ct parallel flow absorption systems are higher than the single effect and the half effect cycles. For the double effect cycle COP and ECOP are found as 1.196 and 0.284, and for the single effect cycle COP and ECOP are found as 0.68 and 0.254, respectively. For the half effect cycle COP and ECOP are found as 0.455 and 0.24, respectively. For each component the exergy loss is calculated. Most of the irreversibilities are found in the evaporator and in the absorber. It is concluded that the performance of the evaporator and the absorber is crucial for the three cycles. Better design and improving of these two components will directly improve and affect positively the performance and the working conditions of the three cycles.
