Pipe Network Optimization in District Cooling/Heating System: A Review

Because the pipe network system is the most important part of the district cooling/heating system, pipe network optimization is the key factor of district cooling/heating system efficient and successful operating. The optimization techniques of pipe network system used in the engineering can not only save a lot of money, reduce the energy consumption, but also can improve the entire pipe network hydraulic conditions. This paper presents a comprehensive review of all significant research on district cooling/heating pipe network optimization in three aspects: network layout, pipe diameter and operation. The characteristics and scope of application of all kinds of optimization algorithm are analyzed. Likely future developments are discussed at the end of this paper.
