Abstract
The paper deals with the problems of thermal processes modeling, which occur in the elements of the system "human - thermal protection - environment." The simulation method of heat transfer processes in the human thermoregulatory system (HTS) is presented. Mechanisms of HTS aimed to support thermal comfort of the human organism and mechanisms of regulation internal heat sources described. Presented an analysis of influence of external work at the redistribution of the heat transfer fluid between the "core" and "shell". The analysis of cumulative heat loss, depending on the power of the internal heat sources, described the contribution of individual components of the heat flux for different values of power. Submitted the results of the modeling studies about the effect of internal heat sources characteristics (constant and variable) on the heat loss, average mass temperatures of the elements and on the temperature at the boundaries of elements layers. A separate study is devoted to the analysis of the effectiveness of physical exercise at different ambient temperatures, taking into account the external insulation (protective clothing). The results may be useful in the development of the systems individual protection and rehabilitation from thermal overheating and overcooling.
Keywords: processes of heat and mass transfer, internal heat sources, thermal resistance, heat insulation, low temperature.
