AN OVERVIEW OF OZONE-SAFE REFRIGERANTS FOR CENTRIFUGAL CHILLERS.

Author(s) : STATT T. G.

Summary

IN THE UNITED STATES, MANY LARGE BUILDINGS ARE COOLED BY CENTRIFUGAL CHILLERS, WHICH CAN RANGE IN SIZE FROM 150 TO 8,000 TONS (520 TO 28.100 KILOWATTS). IN 1986, 38 MILLION LB (17 MILLION KG) OF FULLY HALOGENATED CHLOROFLUOROCARBONS (CFCS) WERE USED BY THESE CHILLERS. BASED ON COMPARISONS OF NORMAL BOILING POINTS, MAJOR CONCLUSIONS WERE THAT R123, R123A, AND POSSIBLY R152 AND R141B APPEAR AS PROMISING ALTERNATIVES FOR R11. FIVE REFRIGERANTS (R134, R22, R134A, R143A, AND R152A) APPEAR AS PROMISING REFRIGERANTS FOR REPLACING R12. THREE REFRIGERANTS (R22, R134A, AND R32) APPEAR AS PROMISING REFRIGERANTS FOR REPLACING R500. FINALLY, 4 NONAZEOTROPES APPEAR AS POSSIBLE REPLACEMENTS FOR BOTH R12 AND R500 ; THEY ARE R32-R134, R32-R142B, R143A-R142B, AND R22-R142B.
