Abstract:The present study investigates the operation status of a user-side thermal facility where thermal energy is supplied from main Korean district heating system and distributed to many household spaces. On-site measurements are made on the operation conditions of a user-side thermal facility and then exergy analysis method is applied to the measurement results to determine the locations and the magnitudes of exergy loss/destructions. In addition, based on the exergy analysis results, overall exergy efficiency and heat exchanger effectiveness of the user-side thermal
facility are calculated.
Keywords:User-side thermal facility, exergy analysis, heat exchanger, mixing, exergy efficiency
