In order to improve the energy performance of a district heating and cooling (DHC) system, retro-commissioning was studied using simulation based on mathematical models, and improved operation schemes were searched to reduce energy consumption. This paper describes the method of determining the optimal cooling water temperature and the validation of the method using experiments. The simulation model of chiller and cooling tower is improved using experimental data, and the simulation error of the chiller subsystem energy consumption was reduced to 1.5%. The optimal cooling water temperatures are calculated using the improved models. If the cooling water temperatures can be setted at optimal values hourly, energy consumption of the chiller system can be reduced by 2.6%, compared with present set point 27.5℃.
