Analysis of district cooling system

With an actual example project in Guangxi Zhuang Autonomous Region, by simulation and theoretical calculation, analyses the three common issues of load calculation, energy saving control strategies and cooling loss of secondary pipeline. The result shows that the equivalent full load rate of the project is 0.37, and that the energy performance of system is improved significantly resulting from the improved loading rate of refrigerating units with optimal operation strategy, and that cooling loss of trench buried pipe is greater than that of direct buried pipe, and in given pipe buried mode, cooling loss of pump operation is the largest, followed by that of supply pipeline, and that of return pipeline is the least.
