Energy and exergy analysis of an absorption power cycle

The exergy destruction of both the absorption and the conventional cycle was also analysed. In a conventional Rankine cycle, the constant temperature at which phase change occurs leads to higher temperature differences between the operating fluid and the heating and cooling external fluids, producing high exergy destruction. The absorption cycle permits a better temperature match, reducing the exergy destruction. Therefore, the exergetic efficiency of the absorption power cycle is around 10% higher than that of the conventional Rankine cycle.
