제로에너지 솔라하우스의 태양열원식 히트펌프 시스템 난방 성능 분석 연구

The performance of a SAHPS(Solar assisted Heat Pump System) is analyzed by numerical simulation, TRNSYS 15. The dual evaporator of The SAHPS are used as a solar heated fluid and an ambient air. A parametric study is performed in this study to assess sensitivity of collector area and storage tank volume. We concluded that collector area and storage volume are the primary variables, COP is higher than that of conventional heat pumps. Therefore, collector efficiency can be enhanced with SAHPS during a heating season.
