Abstract：
Develops the recovery and utilization experimental system of sewage heat energy based on water-source heat pumps. Obtains the technique of indirect heat exchange by PAP to reclaim sewage heat energy and resolves the key problem of the utilization of urban sewage heat energy, i.e., corrosion of heat exchangers. The experimental results show that the system can satisfy the demand of heating in winter with the average COP of the system up to 32.
