Summary

PRESENTS COMPUTERISED SIMULATION AND DESIGN OF SOLAR OPERATED NH3-H2O ABSORPTION REFRIGERATION CYCLES. THE PROGRAM RECEIVES INPUT DATA AND CALCULATES THE BUILDING COOLING AND HEATING LOADS INITIALLY. NEXT THE ABSORPTION CYCLE IS DESIGNED ALONG WITH THE SOLAR COLLECTORS AND AUXILARIES. VARIOUS ECONOMIC PARAMETERS ARE ALSO CALCULATED FROM WHICH THE MOST FAVOURABLE SYSTEM MAY BE SELECTED. TWO EXAMPLES WERE RUN, ONE FOR THE KNESSET BUILDING IN JERUSALEM AND THE OTHER FOR AN AMERICAN OFFICE BUILDING. RESULTS INDICATED THE EXISTENCE OF VARIOUS MINIMAL OPERATING PARAMETERS, EG COLLECTORS' OUTLET TEMPERATURE, ETC. AT THE 1979 RATE OF ENERGY COST INCREASE IN ISRAEL THE SYSTEM PAYBACK PERIOD WAS ESTIMATED AT 9 YR WITH A PRESENT VALUE TOTAL SAVING OF 42.5 MILLION DOLLARS. YET HIGHER VALUES WERE OBTAINED FOR THE AMERICAN OFFICE BUILDING AT ABOUT 81 PERCENT SOLAR FRACTION FOR THE COMPOUND COOLING AND HEATING SEASON. (INT. BUILD. SERV.
