동적 시뮬레이션을 이용한 태양열-지열 이용 하이브리드 시스템의 최적운전법 개발에 관한 연구

Recently, in order to reduce the energy consumption of the cooling and the heating in the field of the architectural, heat pump systems using renewable energy have been developed and used in various applications. In many researches, integrated heat pump systems are suggested which use solar and geothermal heat as the heat source for cooling and heating. However, it is still difficult to get a optimum design of the systems, because the characteristic of heat exchange in each system is complicated and various. In this research, the simulation of the hybrid heat pump system was developed by TRNSYS 17. This paper describes the summary of the suggested three systems and the results of the simulation. The heating loads, average temperature of the heat source, power consumption and COP were calculated with the cases of different system composition and different operation time. As the results, we knew that the composition of system 2 was more efficient and we also grasped the power consumption of the systems.
