Summary

A NEW APPARATUS FOR MEASURING THE PVT PROPERTIES OF FLUID MIXTURES WAS DESIGNED AND CONSTRUCTED. THE APPARATUS WAS EXAMINED FOR PERFORMANCE BY THE MEASUREMENTS OF THE PVT PROPERTIES OF R22. THE PVT PROPERTIES OF A MIXTURE OF 80 WT% R12 + 20 WT% R22 WERE MEASURED IN THE RANGE OF TEMPERATURES 293 TO 418 K, PRESSURES 0.7 TO 9.6 MPA AND DENSITIES 141 TO 1049 KG/M3. TWO HUNDRED PVT MEASUREMENTS WERE MADE ALONG THE 13 ISOCHORES. BASED ON THE OBTAINED DATA, DEW-AND BUBBLE-POINT CURVES WERE DETERMINED AND THE AVAILABLE ESTIMATION METHODS WERE DISCUSSED.
