Abstract
A mathematical model for freezing dispersive waterlogged soils, developed by the authors, is shown. The kinetic of temperature changes in waterlogged soil with the distance from the surface combined with the decrease of the environment temperature is demonstrated. The boundary problem of analyzing cooling medium freezing kinetic of has been formulated. The design fata on the heat transfer from ice to water are experimentally shown to meet the physical sense of the phenomenon in question.The technique developed is simple and easy to use. It is based on the application of modern information technologies.The calculation can be made during substantiating the preparation of the so-called eutectic plates in refrigerator vans, which are used in the technology of machineless cooling based on holdover plates. The technique developed can also be used in mathematical modelling of the processes in the related fields of low-temperature treatment.

Keywords: modelling, ice, moisture content, heat transfer, phase transfer, melting, freezing.
