Long-term Energy Performance and Optimal Operation for Ground-Source Heat Pump

Abstract

Based on five years of operation of a ground source heat pump system, the long-term operational performance and optimum operating conditions of the system were investigated. It was confirmed that the system operated stably during the study period and that there was no significant performance degradation due to long-term operation. Lastly, as part of the study of optimal operating conditions, a heat source water distribution would maximize the performance of the heat exchangers investigated, and it is effective to search for the optimal operation plan based on actual operation data, as in this case, in order to guarantee the long-term operating performance of this system.
