A correlation predicting thermal conductivity of liquid halogenated hydrocarbons

Tsvetkov O.B. , Laptev Yu.A.

Abstract
The need for and uses of transport properties while selecting halogenated hydrocarbons and their mixtures for the vapour compression cycle are reviewed. A correlation is given for heat conduction of fluorocarbons and their mixtures using the theoretical approach suggested by L.P. Filippov. The predicted heat conduction data obtained for saturated liquid state have been compared with the data from other authors.

Keywords: halogenated hydrocarbons, refrigerants, heat conduction, mixtures of refrigerants, saturated liquid.
