Exergy Analysis of Absorption Power Cycle Depending on Source Temperatures

Kyoung Hoon Kim
Abstract—The absorption power generation systems using ammonia–water mixture as a working fluid are proven to be the feasible method for utilizing a low-temperature heat source in the form of sensible energy. In this paper, an exergy analysis is carried out for an absorption power generation system of Kalina cycle using ammonia-water mixture as the working fluid for efficient conversion of low-temperature heat source. Effects of the ammonia mass fraction and the heat source temperature are parametrically investigated on the exergy destruction of each component of the system and the exergy efficiency of the system. Results show that the exergetical performance is greatly affected by the heat source temperature and the ammonia mass fraction of the working fluid.

Index Terms—Ammonia-water mixture, absorption power generation, exergy, Kalina cycle.
