Abstract
The thermal conductivity of the R-32/R-125 (15/85) mixture was investigated in the range of temperatures of 305–411 K and pressures of 0.1–1.8 MPa. Measurements were carried out by the stationary method of coaxial cylinders. The error of the experimental data on thermal conductivity was 1.5–2.5 %, and the measurement errors of temperature and pressure did not exceed 0.05 K and 4 kPa, respectively. A generalizing equation for calculating the thermal conductivity as a function of pressure and temperature was obtained. The thermal conductivity on the dew line and in the ideal gas state was determined.
