The SYNTHSEP methodology that presents a general procedure to derive a complex system configuration of thermodynamic systems operating with a pure working fluid was proposed by A. Lazzaretto and A. Toffolo et al. In this methodology, the designers focus on a set of fundamental thermodynamic processes (compression, heating, expansion, and cooling) in the flowsheet, which is called as the "basic configuration", and it is defined by aggregating certain elementary thermodynamic cycles. In previous studies, this methodology was applied to the absorption refrigeration cycle by Seki et al. for a water-lithium bromide system used as a working fluid pair. By aggregating certain elementary thermodynamic cycles, the cycle configuration and operating point equivalent to the absorption refrigerator that had been considered optimal were demonstrated by a case study. Based on these works, this study redefines a part of the bottom-up synthesis methodology to apply to an absorption power system. In a case study considered for this research, elementary thermodynamic cycles were operated with an ammonia-water mixture. The proposed methodology for optimization is demonstrated by performing a case study for an absorption power cycle with thermal efficiency as an objective function.
