Abstract
This article discusses the problem of desogning an energy-efficient air regeneration system. To achieve this goal, it is necessary to solve two main tasks: obtaining oxygen with minimal energy consumption and absorbing carbon dioxide with the least resistance and energy consumption for the technological module absorbing carbon dioxide. An analysis of known methods for producing oxygen shows that a method based on chemical reactions is the most acceptable for solving this problem. When evaluating the methods of carbon dioxide absorption, the absorption method was chosen due to absorption columns’ having low resistance, therefore, this method minimizes energy consumption. To verify the correctness of the selected concepts, it is necessary to design and manufacture an experimental stand and conduct a series of field tests. The schematic diagram of the stand is shown. When designing the stand, the necessary equipment was calculated and selected, as well as technological processes providing the specified parameters were considered. The energy consumption of the module is determined by the integration of all components of the air regeneration system.

Keywords: air regeneration, oxygen generator, carbon dioxide absorption, energy efficiency, sealed compartment.
