Viscosity and thermal conductivity of R152a.

Author(s) : KRAUSS R., STEPHAN K.

Summary

Based on reliable measurements the authors have developed formulations for the viscosity and thermal conductivity of R152a covering a temperature range 240-440 K at pressures up to 20 megapascals and densities up to 1050 kg/m3, respectively, including the critical region. The ascribed overall uncertainty of the background terms is about more or less 3% for viscosity and more or less 5% for thermal conductivity. The data analysis showed partly considerable inconsistencies between series of measuremnts from different laboratories. The authors have specified regions where further reliable measurements are needed.
