Abstract

This paper presents a basic energy performance data of microturbine, renewable Energy(BIPV and Solar Collector System) and a hybrid energy system(geothermal system and microturbine) installed in hospital building. The efficiency of solar collector and BIPV system was 30[%], 10[%] individually, and lower than micro turbines. Finally, in energy performance aspect, microturbine and geothermal source heat pump system were a high-efficiency system in hospital building. It is confirmed hybrid energy systems also show the most powerful alternative energy system for green hospital building from the simulation results.

본 논문은 대형 병원 건물에 신재생에너지 및 열병합시스템을 설치하였을 경우 에너지 성능해석 및 경제성평가를 도출한 것이다. 태양광, 태양열, 지열, 마이크로터빈 및 마이크로터빈과 지열을 복합한 하이브리드 에너지시스템에 대하여 각각 분석하였다. 분석결과 지열 및 마이크로터빈 시스템이 비교적 양호한 결과를 얻었으며 특히 하이브리드시스템으로 운전하는 경우 병동부의 냉난방공급이 가능하고 경제성평가에서도 매우 좋은 결과를 나타냈다. 이는 빌딩 스마트 그리드시스템의 에너지해석 및 경제성평가 방법을 통한 시스템 구축에 필수적인 자료 활용할 수 있다.
