Abstract
The report gives results of an evaluation of transport properties of 1,1,1,2,3,3-hexafluoropropane (HFC-236ea), with liquid viscosity and thermal conductivity being the two main transport properties of interest. In addition, the specific heat and density of refrigerant/lubricant mixtures are also provided in this study. The study used a novel method for simultaneously measuring viscosity and thermal conductivity, using inline property sensors in series with a heat transfer measurement system. Specifically, viscosity was measured with an inline torsional oscillation viscometer, and thermal conductivity was measured from the knowledge of single-phase heat transfer characteristics of a heated test section. For HFC-236ea, the measured data were compared with REFPROP, a theoretical prediction package developed by the NIST (National Institute of Standards and Technology): average deviations were within +15% in thermal conductivity, and -5% in viscosity.
