| Abstract: | in order to study the design of the power subsystem and exchanger network in the distributed energy systems, with the distributed energy system in Aide Hospital as the object of study, the hot and cold stream in distributed energy systems with the pinch technology is analyzed, then the location of the pinch is found. At the same time the improvement strategy of the heat exchanger network is analyzed, and the exchanger network i~ improved. The result shows that, the internal combustion engine has a good advantage as power subsystem, and the requirement of the heat load reduce 107.07 kW through the optimizing design of the heat exchange network, which has decreased the consumption of energy greatly. The saving effect was remarkable. |
