Summary

By using an ejector refrigeration cycle, cooling demand can be supplied from solar thermal energy with little power consumption. The cycle’s COP has already obtained over 40 at 60 °C generator temperature in our experiments. A photovoltaic/thermal (PV/T) solar panel, which can convert solar energy into heat and electricity, was developed in 2020 by the present authors. The panel can supply electricity and hot water up to about 70 °C. A system combining the PV/T solar panel with the ejector refrigeration cycle has the potential to supply space cooling by using solar energy with little power consumption. This paper focuses on the cooling in Tokyo and Paris by the simulation calculation based on existing results. The results showed that the ejector refrigeration cycle’s heat output accounts for 45.9 % of the cooling demand, with the cycle’s COP being 38 to 45 in a low-humidity environment in Paris.
