Abstract :
The coefficient of performance (COP) is one efficient important evaluating indicator in the urban sewage heat pump system. Based on the engineering thermodynamics principle, the heating operating performance of direct and indirect systems have been analyzed and compared. The results indicate that the actual COP of direct sewage source heat pump system is higher approximately 0.3 than that of indirect system, and the influence of the sewage temperature and the user supply water temperature are big to the system performance while it is small on the temperature differences of sewage, intermediary water, the evaporator or the condenser.
