B-21 Potential for the Energy Efficiency Advancement in District Heating and Cooling Plant by Renovation (Part-1)

Abstract

Energy efficiency improvements of renovated district heating and cooling (DHC) plants were evaluated by simulation. In this paper, the simulation model for the original plant is developed based on the equipment specifications of the original plant. Accuracy of this model is examined based on the comparison to the measurement energy consumption data of original plant. From the result of this comparison, few parameters related to the chiller operational control were modified and chiller efficiency change due to the degradation was considered.
