Özet

Exergy analysis helps identify the amount and the positions of exergy losses in any system along with its main components. To achieve sustainability, these irreversibilities should be diminished. This study aims at presenting the exergetic-based performance of a sewage water source heat pump system based on experimental data. Initially, the exergetic performance assessments are carried out and then the exergetic performance results are evaluated using exergy-based sustainability indicators. The SWSHP system had the values for exergetic efficiency 57.77%-63.81% and overall sustainability index 2.31-2.72, respectively. Eight other exergy-based indicators are applied to determine and compare the most impacted component among the others.
