Development of an improved Stirling cooler for vacuum super-insulated fridges with thermal store and photovoltaic power source for industrialized and developing countries.

Summary

The performances of a free-piston Stirling cooler and a super-insulated refrigerator specifically designed for high-efficiency household refrigeration are presented. Photovoltaic (PV) power is used without battery back-up. Overnight operation is ensured by the presence of a "cold store". The cooling system modulates according to thermal load and available PV power and maintains high part-load efficiency. Preliminary results suggest that an energy consumption of below 50 kilowatthour/year is possible.
