Improved Plastic-Al Pipe Based System for Refrigeration of Energy Existed in Urban Sewage

Abstract:

In order to recover the urban sewage energy ,a lab-scale equipment for the sewage energy recovery based on water source heat pump was developed and researched experimentally .The technique of indirect heat exchange by the plastic-Al pipe to recover the urban sewage energy, i.e., the corrosion of the heat exchanger, laying the foundation for the practical utilization of sewage energy. The experimental results show that the developed system is favorable to the environment protection and energy conservation, satisfying the cooling duty requirement with the average coefficient of performance 4.15 in the open cycle system and the average coefficient of performance 3.64 in the close cycle system.
