대수층 축열 지열원 열펌프 시스템의 일일 난방 성능 특성

The aim of this study is to investigate the daily heating performance of a heating and cooling system with aquifer thermal energy storage(ATES) known as one of the underground thermal energy storage application systems. The heating and cooling system was composed of heat pump unit and ATES, which was installed in a factory building located in Anseoung. The system represented very high heating performance due to the stability of EWT from ATES. Daily average heat pump unit COP and system COP were 5.2 and 4.0, respectively.
