Summary

SOLAR REFRIGERATION IS ESPECIALLY ATTRACTIVE IN ISOLATED REGIONS. THE DANUBE DELTA NEEDS ICE FOR FISH PRESERVATION. THE PAPER DESCRIBES AN INTERMITTENT SINGLE-STAGE AMMONIA-WATER SOLAR ABSORPTION SYSTEM OF 46 MJ/CYCLE. SOLAR COLLECTORS HEAT THE GENERATOR. INSTALLATION DETAILS AND EXPERIMENTAL RESULTS ARE PRESENTED. THE COPSYSTEM VARIES BETWEEN 0.152 AND 0.09 IN THE PERIOD OF MAY-SEPTEMBER. SOLAR RADIATION AVAILABILITY AND THE THEORETICAL COP ALSO APPLICABLE TO THE TROMBE-FOEX SYSTEM, ARE ASSESSED. REFERENCE IS MADE TO EVACUATED SOLAR COLLECTORS WITH SELECTIVE SURFACES. ACTUAL COPSYSTEM VALUES OF 0.25-0.30 CAN BE ACHIEVED AT GENERATION AND CONDENSATION TEMPERATURES OF 353 AND 297.3 K (80 AND 24.3 DEG C) RESPECTIVELY. FOR BIGGER CAPACITIES OF 450-675 MJ/DAY, THE PAY-OFF PERIOD IS ESTIMATED TO BE 6 AND 4 YEARS RESPECTIVELY AND THE LIFETIME TO 15-18 YEARS.
