Abstract: Energy efficiency improvements of renovated district heating and cooling (DHC) plants were evaluated by simulation. In this paper, the simulation models for the original and renovated plants are developed based on the equipment specifications of the original plant. Accuracy of this model is examined based on the comparison of the measurement data from the operations of the original plant. From the result of this comparison, few parameters related to the chiller operational control and chiller efficiency were modified. In the final part of this paper, the model quantifies the expected total annual energy efficiency improvement and the contribution of each piece of replaced equipment.
