Summary

SOLAR REFRIGERATION AND HEATING FACILITIES USING 1,330 M2 OF CPC CONCENTRATORS WERE APPLIED TO AN HOSPITAL ESTABLISHED IN MARCH 1984. RESULTS WERE EVALUATED WITH COLLECTOR EFFICIENCY, COP OF REFRIGERATION, COP OF THE SYSTEM, SYSTEM EFFICIENCY AND PERCENTAGE OF SOLAR DEPENDENCE. RESULTS FOR REPRESENTATIVE DAYS IN SUMMER, WINTER AND INTERMEDIATE SEASON WERE SHOWN IN DETAIL AND COMPARED WITH THE CALCULATED RESULTS, WHICH SHOWED SATISFACTORY AGREEMENT. IT WAS DISCLOSED THAT THE CAREFULLY DESIGNED CPC-COMBINED SOLAR REFRIGERATING AND HEATING PLANT COULD BE OPERATED EFFICIENTLY, SAFELY AND STABLY WITH THE AID OF OPTIMAL CONTROLS, DUE TO THE HIGH TEMPERATURE DIFFERENCE TO BE UTILIZED AND THE EXCLUSION OF BOILING AS WELL AS FREEZING BY APPLYING SILICONE OIL AS THE HEAT MEDIA IN THE COLLECTOR CIRCUIT.
