The article investigates the temperature-humidity characteristics zones "freshness" of household refrigerating appliance. The paper presents the results of measurements of temperature and moisture characteristics in the section "freshness" in refrigerator-freezer «Indesit BIA181 NF». The obtained results of the experiments, experimental studies have shown that the parameters of temperature and humidity of air in the area of ​​"freshness" are in a wider range in comparison with the required their ra-tional values, which is the reason for the decline of quality cold storage.

It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.
