| Research Abstract |
The precise measurements of PpTx property, saturation properties,and critical parameters have been performed in the liquid, super-critical, and saturationregions for the CO2/hydrocarbon mixtures, which are expected as long-term alternatives forrefrigeration and heat-pump systems. As the results, the reliable measurement data wereobtained in the wide ranges of temperatures, pressures, densities, and compositions. Theobtained data were systematically compared with the available thermodynamic propertymodels, from which the necessity of the improvements of the models could be confirmed.
