Abstract
The working principles of wastewater source plant both as a water chiller and a heat pump and performances of wastewater source are briefly introduced.Then,calculating formulas on exergy destroys in refrigeration and heat pump states of main units in wastewater source plant and exergy efficiency of this kind of plant were minutely stated,which were used to analyze exergy destroys in main units and exergy efficiency of the plant with different temperature wastewater sources in refrigeration and heat pump states.According to the results,efficient approaches to increase exergy efficiency of wastewater source plant both as a water chiller and a heat pump are presented.
