Abstract
The working principles of wastewater source plant both as a water chiller and a heat pump and performances of wastewater were briefly introduced in this paper.Then,calculating formulas on exergy destroys in refrigeration and heat pump states of main units in wastewater source plant,exergy efficiency of this kind of plant and primary energy rate were minutely stated ,which were used to analyze and compare exergy destroys in main units and exergy efficiency of the plant and PER with different temperature wastewater sources in refrigeration and heat pump states.According to the results,R407C was the ideal working substance.
