Research on energy consumption of multi-source networked transmission and distribution cooling system

At present, there are mainly two forms of district cooling: centralized transmission and distribution and distributed transmission and distribution. Generally, most of them are characterized by centralized energy stations, large pipelines and long-distance transmission and distribution, leading to high energy consumption and poor economy under low load conditions. In view of the above problems, this paper proposes a multi-source networked transmission and distribution cooling system, in which each user builds energy stations separately (multi-source) and connects each energy station through a pipeline network, so as to achieve energy self-sufficiency for each user during the medium and low load periods, and be supplemented by other energy stations (multi-source) during the peak load period. By calculating the energy consumption of centralized transmission and distribution system, distributed transmission and distribution system, and multi-source networked transmission and distribution system, the results show that the multi-source networked transmission and distribution system saves 41% energy compared to the centralized transmission and distribution system, and 23% energy compared to the distributed transmission and distribution system.
