PERFORMANCE EVALUATION OF PURE AND MIXED REFRIGERANTS IN DOMESTIC REFRIGERATORS: DROP-IN REPLACEMENT OF R12.

Author(s) : JUNG D. S., RADERMACHER R.

Summary

IN SIMULATING A STEADY-STATE THERMAL SYSTEM, BOTH SUCCESSIVE SUBSTITUTION AND NEWTON-RAPHSON METHODS ARE EMPLOYED INDEPENDENTLY AND YIELDED THE SAME RESULTS WITHOUT ANY SIGNIFICANT DIFFERENCE IN THEIR PERFORMANCE. AN EXTENSIVE SCREENING WAS CARRIED OUT FOR 15 PURE AND 21 MIXED REFRIGERANTS. RESULTS INDICATE THAT NO SINGLE PURE FLUIDS MAY BE A DROP-IN REPLACEMENT FOR R12 DUE TO THE MISMATCH OF VOLUMETRIC CAPACITY EVEN IF A FEW FLUIDS SUCH AS R22, R152A, R142B, R141B HAVE A COMPARABLE COP TO R12. ONLY R22-R142B AND R32-R142B MIXTURES YIELDED AN INCREASEIN COP UP TO 3% WITH THE SAME CAPACITY AS THAT OF R12. IN THE SHORT RUN, THESE MIXTURES MAY BE SUBSTITUTED FOR R12.
