Evalution of distribution system performance in district heating and cooling system

In this study, energy simulation program of heat distribution network in a district heating and cooling system was developed. Research on actual condition of heat distribution system of DHC plant was also executed. Using the measurement result, the accuracy of the program is confirmed. Using this program, the relationship between scale of pipeline network and energy consumption of heat distribution system was examined. In the final part, importance of chilled water temperature differences at the building side for energy performance of DHC is clarified quantitatively.
