Mj. Assael et L. Karagiannidis, MEASUREMENTS OF THE THERMAL-CONDUCTIVITY OF LIQUID R32, R124, R125, AND R141B, International journal of thermophysics, 16(4), 1995, pp. 851-865
This paper reports measurements of the thermal conductivity of refrige
rants R32, R124, R125, and R141b in the liquid phase. The measurements
, covering a temperature range from 253 to 334 K and pressure up to 20
MPa, have been performed in a transient hotwire instrument employing
two anodized tantalum wires. The uncertainty of the present thermal-co
nductivity data is estimated to be +/- 0.5%. The experimental data hav
e been represented by polynomial functions of temperature and pressure
for the purposes of interpolation. A comparison with other recent mea
surements is also included.
