TRNSYS를 이용한 실증용 지열시스템 성능 시뮬레이션

The objective of this study is to analyze the performance of a ground source heat pump system with vertical and horizontal type ground loop heat exchangers. The geothermal system were installed in a hotel building located on the outskirts of Seoul. The ground source heat pump system of the field site building will be monitored continuously in this year. In this study, the performance and annual power consumption of two systems were compared as the results of the TRNSYS simulation. The COP of the vertical type ground source heat pump system was 1.7-9.6% higher than that of the horizontal type ground source heat pump system. In addition, The power consumption of the former heat pump system was about 6.1% lower than that of the latter.
