공기열원 히트펌프를 위한 공기식 지중 열교환기(GAHX) 설계 및 분석 연구 = Ground Air Heat Exchanger Design and Analysis for Air Source Heat Pump

다국어 초록 (Multilingual Abstract)

A ground air heat exchanger (GAHX), also called earth air heat exchanger is a useful technology to be integrated with other renewable energy technologies. In this study, ground-air heat exchanger system for the air source heat pump is introduced. The purpose of this study is to design the volumetric flow rate and the length of GAHX system. A GAHX length model equation has been developed and used for calculation. GAHX thermal efficiency are recommended as 75% and 85% in order to optimize pipe length. 2,750 m3/h, 2,420 m3/h of volumetric flow rate on 88.3m, 111.7m length are suggested for providing 7.5kW thermal capacity. And the number of path is recommended more than two to minimize pressure drop. For future study, advanced model equation study with ground thermal behavior and a more efficient GAHX design will be considered.
