Summary

Hydrofluoroether 1,1,1,3,3,3-hexafluoro-2-methoxypropane (HFE-356mmz) is a promising candidate of low global warming working fluid in high-temperature heat pumps and organic Rankine cycle. In this study, the thermal conductivity was measured by using a transient hot wire method in the conditions of temperature from 319 to 462?K and pressure from 0.5 to 4.0?MPa for the liquid phase, and temperature from 393 to 452?K and pressure from 0.18 to 1.04?MPa for vapor phase. The combined standard uncertainties of thermal conductivity measurements were estimated to be less than 2.3% at liquid and 2.6% at vapor phases. On the other hand, the kinematic viscosity was measured by using tandem the capillary tubes method over the temperature range of 313–454?K for liquid and from 393 to 475?K for vapor phase up to 4.00?MPa. The uncertainties in liquid and vapor phases were estimated to be less than 2.9% and 3.0%, respectively. Also, correlations have been developed for saturated liquid and vapor.
