Abstract

Measurements of <i>PρTx</i> properties for five compositions of the binary R 245fa + R 134a mixture were made by the isochoric method<tt>.</tt> With respect to 90.00 mass%, 70.00 mass%, 50.00 mass%, 30.00 mass%, and 20.00 mass% R 245fa mixtures, 134, 125, 119, 122, and 43 <i>PρTx</i> data were obtained in the temperature range from 310 K to 430 K, and pressure up to 6.94 MPa, respectively. The vapor-liquid equilibrium data were determined with an aid of the break point along the isochores. The critical pressure for five compositions were measured and the correlation of the critical locus for the R 245fa + R 134a mixture was also formulated.
