AN EVALUATION OF 2 REFRIGERANT MIXTURES IN A BREADBOARD AIR CONDITIONER.

Author(s) : MULROY W.

Summary

AN EXPERIMENTAL WATER-TO-WATER BREADBOARD HEAT PUMP WAS CONSTRUCTED FORCOMPARISON OF PURE R22 TO THE REFRIGERANT MIXTURES R22-R114 AND R13-R12. THREE EVAPORATOR CONFIGURATIONS WERE EXTENSIVELY STUDIED. IN ALL CASES THE BEST MIXTURE OUTPERFORMED R22. THE BEST EFFICIENCY WITH R22-R114 WAS 32% HIGHER AND WITHR13-R12 WAS 16% HIGHER THAN THE BEST EFFICIENCY MEASURED WITH R22. HEAT EXCHANGE BETWEEN THE CONDENSED AND EVAPORATING REFRIGERANT IS BENEFICIAL TO SOME MIXTURES. MIXTURES EXHIBIT NONLINEARITY OF ENTHALPY VERSUS TEMPERATURE IN THE TWO-PHASE REGION WHICH HAS SIGNIFICANT IMPACT ON BOTH HEAT EXCHANGER AND CYCLE DESIGN.
