지열-태양열원 복합시스템의 성능평가에 관한 연구 = A Study on the Performance Evaluation of Hybrid Energy System with Geothermal and Solar Heat Sources

다국어 초록 (Multilingual Abstract)

The present study concerns the annual performance evaluation of a hybrid- renewable energy system with geothermal and solar heat sources for hot water, heating and cooling of the residential buildings. The hybrid energy system consists of ground source heat pump of 2RT for cooling, solar collectors of 4.8m2, storage tank of 250liters and gas fired backup boiler of 11.6kW. The averaged coefficients of performance of geothermal heat pump system during cooling and heating seasons are measured as 4.1 and 3.5, respectively. Also solar fraction for hot water is measured as 35percent. Overall, the results shows that the hybrid-renewable energy system satisfactorily operated under all climatic conditions.
