59. PV/Tソーラーパネルとエジェクタ冷凍サイクルを組み合わせた太陽エネルギー利用システムの検討

抄録

Our research group has already developed a photovoltaic/Thermal (PV/T) solar panel, which can utilize 73 % of solar energy as electricity and hot water in the highest case. On the other hand, how to use the PV/T solar panel is the next important subject. This paper reports the simulation approach for utilizing the hot water especially in summer by introducing an ejector refrigeration cycle, which can supply cooling energy at 15 °C from the hot water at about 60 °C. From the simulation, the importance of the development of a new system design for utilizing solar thermal as cooling, heating, and hot water supply through a year is concluded.
