The liquid thermal conductivity of R32 (CH{sub 2}F{sub 2}) and R134a (CF{sub 3}CH{sub 2}F) was measured in the range from 223 to 323 K and from 2 to 20 MPa by the transient hot-wire method. The thermal conductivity of the R32+R134a mixture was also measured in the same range by varying the mass fraction of R32. The measured data are analyzed to obtain a correlation in terms of temperature, pressure and composition of the mixture. The uncertainty of our measurements is estimated to be within {+-}2%.
