Abstract
The coaxial cylinder method was used to measure the thermal conductivity of the R32 and R134a refrigerants and R32–R134a zeotropic mixture. The results are presented, and the overall accuracy of the measurements is assessed.

Keywords: thermal conductivity, coaxial cylinder method, fluorochlorohydrocarbons, R32 and R134a refrigerants, zeotropic mixture, liquid state.
