Summary

THE THERMAL CONDUCTIVITY OF MIXTURES OF R22 WITH R13, R23, R12, AND R114 WAS MEASURED AT TEMPERATURES OF 298.15 AND 323.15 K UNDER PRESSURES FROM ATMOSPHERIC TO SATURATED. THE PRECISION WAS WITHIN 2%. THERMAL CONDUCTIVITY INCREASES WITH INCREASING TEMPERATURE AND PRESSURE AT A CONSTANT COMPOSITION. EACH MIXTURE CHANGE ALMOST LINEARLY WITH THE CONCENTRATION OF R22 AT A CONSTANT TEMPERATURE AND PRESSURE, ALTHOUGH THE THERMAL CONDUCTIVITY AT EACH COMPOSITION IS SLIGHTLY LARGER THAN THE CALCULATED VALUES BY A SIMPLE MOLE-FRACTION AVERAGE METHOD. THE EXPERIMENTAL RESULTS WERE CORRELATED BY EMPIRICAL EQUATIONS AND COMPARED WITH SEVERAL PREDICTION METHODS.
