Abstract

In order to upgrade the waste heat to higher process temperatures for recuperation, an ejection absorption heat transformer gives more an effective potential for that purpose and higher system performance than a single-stage one. Thermodynamic analysis, both first and second law, is employed to be a tool for consideration of the quantity and quality of energy in both thermal systems. In this paper, an exergy analysis is comparatively performed on two cycles with lithium-bromide/water as the working pair. The numerical results for the cycle obtained here are tabulated. The thermal properties, entropy, and exergy of the working fluids are also calculated to analyze irreversible loss in system components under operating conditions.
