Zusammenfassung:	This paper briefly reviews measurements and correlations of viscosity and thermal conductivity of alternative refrigerants. The emphasis is on the analysis of similar correlations which expressed the viscosity and thermal conductivity as a function of temperature and density, and which can be used to calculate each property knowing the other. New correlations for the thermal conductivity of R22, R32, R125, R134a and R152a, based on our own measurements in a coaxial cylindrical cells are also reported.
