Exergetic Assessment of Biogas Engine-Driven Heat Pump Systems for Using Sewage Resource

Abstract:

In order to improve energy utilization rate of biogas engine-driven heat pump (BEHP) systems for wastewater treatment plant, the exergy analysis is applied in this paper. The paper concludes the exergy losses and exergy efficiency of each equipment, and reveals the weak link of energy transformation of the whole system. According to the calculation of one example, the location of maximum exergy loss is the biogas engine-driven, while the location of minimum exergy efficiency is the compressor, which provides powerful theoretic references to improve and optimize BEHP systems for wastewater treatment plant.
