홈페이지논문 초록 (Abstract)
Recently, utilization of building foundations as ground-coupled heat exchangers has attracted much attention because they reduce the cost and enhance the heat transfer. The objective of this study is to evaluate the performance of energy-slab ground-coupled heat exch anger installed in a commercial building. In order to demonstrate the energy transfer characteristics of the energy-slab, experiments were c onducted from October 2010 to September 2011. The 1-year measurement res ults showed that the mean EWTs of brine returning from the energy-sl ab were 9.6℃ in heating season and 24.9℃ in cooling season, which wer e in a range of design target temperatures. In addition, the geotherma l heat pump system with the energy-slab showed on-off operation accord ing to the setting temperatures of secondary fluid in water storage ta nk. The results also showed that the energy-slab extracted heat of 198. 6 kW from the ground and injected heat of 318.9 kW to the ground, respectively.
