INTERNAL PERFORMANCE OF A REFRIGERANT MIXTURE IN A TWO-EVAPORATOR REFRIGERATOR.

Summary

WHEN A REFRIGERANT MIXTURE IS USED IN A REFRIGERATING SYSTEM, THE TEMPERATURE RISES DURING A CONSTANT-PRESSURE BOILING PROCESS AND FALLS DURING A CONSTANT-PRESSURE CONDENSATION. IF THE REFRIGERATION APPLICATION REQUIRES COOLING A FLUID THROUGH A TEMPERATURE RANGE, THE MATCH OF THIS RANGE WITH THE EVAPORATING TEMPERATURES WILL POTENTIALLY RESULT IN AN IMPROVED COP. THE COOLING OF AIR IN THE TWO-COMPARTMENT DOMESTIC REFRIGERATOR CAN APPROXIMATE THE DESIRABLE COOLING APPLICATION. THE AUTHOR PRESENTS SOME EXPERIMENTAL MEASUREMENTS ON A TWO-EVAPORATOR SYSTEM WITH A 50% MIXTURE OF R12/R114 AND COMPARES THAT SYSTEM TO THE PERFORMANCE OF A SYSTEM USING R12 ALONE.
