Abstract

The performance of a sewage water source heat pump system is assessed through conventional/enhanced exergy-based methods in this present study. The experimental data used in the analyses are based the cooling mode. According to the conventional-based results, the condenser has the lowest exergy efficiency. Beside this, the enhanced exergy-based analysis results show the sewage water heat exchanger should be considered as the most significant component as it has the highest avoidable exergy destruction rate in the whole system and takes the improvement priority. Based on the enhanced exergy analysis, 56% of the total exergy destruction belongs to the avoidable part.
