Sinopsis

Visual observations of the processes of heat-and-mass transfer in a block of solid CO2 formed in the circulation loop of a bottle-subliminal refrigerator have been carried out. The results of the observation allowed to state the fact of creation of the internal porous structure in the block. The internal porous structure is a dynamic formation the characteristics of which depend on the intensity of phase changes on the boundaries of the block. A mathematical model of heat-and-mass transfer in a such porous substance has been developed.
