Abstract1   지열에너지는 지중의 항온성을 이용하여 냉난방 및 급탕 부하에 대응 가능한 고성능 에너지 절약형 기술로 주목 받고 있다. 하지만 기존의 지열설비 설계 프로세스인 최대부하 계산을 통해 지열설비의 용량을 산출하는 방법은 초기 투자비용이 많이 드는 단점이 있다. 이와 같은 단점으로 인해 지열에너지의 보급이 주춤해지고 있으며 지열설비 시스템의 설계에 대한 보완이 필요하다. 본 연구에서는 최적화 툴을 이용하여 지열설비시스템의 최적화 설계를 진행하였다. 최적화 된 지열설비 시스템의 초기투자비용은 기존의 초기투자비용보다 약 18.6% 감소하였다.
Abstract2   Since the revision of the Rationalization of Energy Use Law, the spread of new and renewable energy in buildings has been promoted. In addition, the production of electric power and thermal energy is an important issue in the change of energy paradigm centered on the use of distributed energy. Among them, geothermal energy is attracting attention as a high-performance energy-saving technology capable of coping with heating / cooling and hot water load by utilizing the constant temperature zone of the earth. However, there is a disadvantage that the initial investment cost is high as a method of calculating the capacity of a geothermal facility by calculating the maximum load. 이The disadvantages of these disadvantages are that the geothermal energy supply is getting stagnant and the design of the geothermal system needs to be supplemented. In this study, optimization design of geothermal system was carried out using optimization tool. As a result of the optimization, the ground heat exchanger decreased by 30.8%, the capacity of the heat pump decreased by 7.7%, and the capacity of the heat storage tank decreased by about 40%. The simulation was performed by applying the optimized value to the program and confirmed that it corresponds to the load of the building. We also confirmed that all of the constraints used in the optimization design were satisfied. The initial investment cost of the optimized geothermal system is about 18.6% lower than the initial investment cost.
