Экспериментальное исследование плотности бинарных смесей хладагентов R23-HFE 347MCC и разработка локального многоконстантного уравнения состояния вириального типа

Аннотация:

The experimental PVTX-data are presented for gas phase, curve of condensation and two-phase region of binary system R23 -HFE 347mcc with concentrations of second component from 12,22 to 30,77 % (mass). The measurements are carried out by isochoric-related method of subsequent expansions in diapasons of temperatures from 288,15...353,15 К at pressures up to 3 MPa. The local equation of state of virial type is elaborated for calculations of thermodynamic properties of system in pointed out region of concentrations and temperatures. The mean square uncertainty of compressibility approximation is 0,086 %.
