Abstract

This paper obtained the changing range of sewage temperature, the inlet and outlet temperatures of the sewage heat exchanger, evaporator and condenser in winter by monitoring the large sewage source heat pump system in Shi Jia-zhuang. By the testing data, the operating performance of the heat pump system was studied. During the heating test, the heat pump system operated steadily and the coefficient of heat transfer of the sewage heat exchanger was 740 W/ (m²·°C), and the average coefficient of performance of the heat pump was 3.76. These can be taken as references for the design and engineering application of the sewage source heat pump systems.
