Presents the analysis method of the energy loss of the distributing pipe network of the district cooling system, and analyses the operating data of the distributing pipe network of the district cooling system. Preliminary analysis results show that in the initial stage of the district cooling system, due to fewer users, the energy loss ratio of the distributing pipe network is relatively large. In the first year of operation, the annual energy loss ratio of the distributing pipe network can reach 12.3%. The energy loss ratio of the distributing pipe network gradually decreases with more customers connected to the network. The energy loss ratio of the distributing pipe network is expected to be less than 2% on the full load condition.
