59. Investigation of a solar energy utilization system using a PV/T solar panel and an ejector refrigeration cycle

Abstract

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.
