Аннотация

The methodology. Theoretical studies of thermal exchange processes in isolating regenerative respirator using the theory of heat-mass and taking into account the process of heating and melting of water ice in the refrigerator.

The results. The dependence and results of the dynamics of the temperature of heating and melting of water ice in the refrigerator are isolated by the regenerative respirator, the error of which in comparison with the data of experiments does not exceed 12%.

Scientific novelty. For the first time a mathematical model of heat exchange processes in the system "environment - isolating respirator-refrigerator is developed, taking into account heat flows penetrating from the external environment through the shell of the respirator, from the human body, absorbed or released by the refrigerator.

Practical significance. These  results allow to determine the thickness and material of the refrigerator shell with lower temperature conduction ratios, which will provide a significant increase in the time of use of the refrigerator regenerative respirator.
