Summary

A SOLAR ICE MAKER WITH A 0.8 M2 COLLECTION SURFACE WAS STUDIED. IT IS AN ADSORPTION MACHINE WITH AN INTERMITTENT DAILY CYCLE THAT USES THE ACTIVE CARBON AC 35-METHANOL PAIR. THE SAME EXCHANGER CAN BE USED EITHER AS AN EVAPORATOR OR AS A CONDENSER. THE SYSTEM CONSISTS IN MOVING THIS EXCHANGER BETWEEN THE THERMALLY INSULATED ICE BANK AND AN AMBIENT-TEMPERATURE WATER TANK, AND IN ACTUATING THE VENTILATION PORTS FOR THE HEATING AND COOLING OF THE COLLECTOR. NO VALVE IS REQUIRED. THE RESULTS SHOW THAT, WITH A COLLECTION EFFICIENCY OF 0.41 AND A THERMAL COP OF 0.40, IT IS POSSIBLE TO OBTAIN A GROSS SOLAR COP OF 0.15 (AS A FUNCTION OF THE QUANTITY OF METHANOL). THIS MACHINE PRODUCED 4 KG OF ICE PER DAY, DURING SUMMER, WHICH CORRESPONDS TO 5 KG PER SQUARE METRE OF COLLECTION SURFACE.
