Discussion on application of energy comprehensive utilization system based on clean heating and IDC heat discharge

Through the comprehensive coordination of the complementary characteristics of various energies and the flexible configuration of various links such as “source-network-load-storage”, local consumption of energy is realized and the comprehensive utilization energy efficiency of the system is improved. Combined with an engineering case in Xi’an, the energy-saving and economic analysis of the system application is carried out. The results show that compared with the traditional scheme, the system can save 1.719 2 million tons of standard coal and reduce 4.286 million tons of carbon dioxide, 28 400 tons of sulfur dioxide, 26 800 tons of nitrogen oxides, and 16 500 tons of soot annually. Moreover, the power usage effectiveness (PUE) of the data center is 1.248. The financial net present value of the actual case is 643.974 7 million yuan, the static investment payback period is 4.43 years, and the dynamic investment payback period is 6.25 years. It has significant energy-saving and economic benefits, providing a reference for relevant regional energy comprehensive utilization system planning projects.
