동적시뮬레이션을 이용한 태양광열-지열 하이브리드 시스템의 성능분석

Ground source heat pump system has been utilized in building with the stable heat supply of ground heat source. However, the system performance in continuous operation may decrease gradually according to the change of underground temperature. The hybrid system based on connection of solar system is one of the other ways for remedy a defect. A hybrid system using both PVT and ground heat pump system has many advantages such as more efficient system performance and smaller system capacity. However, the design and operation method for this system have not been established. In this paper, the performance of a ground source heat pump system with photovoltaic/thermal system was analyzed by a dynamic simulation model. The power consumption and performance efficiency of hybrid system was calculated in operating conditions of control logic including heating and heat storage operation mode. As a result, the system performance was confirmed according to the operation methods in the fixed system capacity.
