Summary

The paper reports new, absolute measurements of the liquid refrigerants. The measurements have been performed in a transient hot-wire instrument employing two anodized tantalum wires as the heat source. A recently developed semiempirical scheme is employed to correlate successfully the thermal conductivity and the viscosity of these refrigerants, as a function of their density.
