The thermal conductivity of solid CF2Cl2 was measured by the linear-flow method in the temperature range 80–115 K under saturated vapor pressure. Special attention is given to the explanation of the heat transfer process under constant density. The temperature dependence of the isochoric thermal conductivity is analyzed within a model in which heat is transferred by phonons and, above the phonon mobility edge, by «diffusive» modes migrating randomly from site to site.
