Abstract
- • HFE-356mmz is a low global warming working fluid. • Thermal conductivity measurements are presented using transient hot wires method. • Kinematic viscosity measurements are reported using tandem capillary tubes method. • Correlations have developed for saturation liquid and vapor. 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. [ABSTRACT FROM AUTHOR]
