Summary

The thermal conductivity coefficient is measured by a steady-state method of coaxial cylinders. The evaluated maximum relative error is to be 3-3.5% with a confidential probability of 0.95. Refrigerants were investigated in the 290-400 K temperature range. In the liquid phase, the measurements were conducted at a pressure from close to the phase transition curve up to 15 MPa and in the gaseous phase, from 0.29 up to 3.63 MPa.
