INVESTIGATION OF THE RELIABILITY OF THERMAL CONTROL OF THE RESOURCE OF PROTECTIVE PROPERTIES OF PRODUCTS BASED ON CHEMISORBENTS ON A POROUS FIBROUS MATRIX
(pp. 51-57)

Abstract. The method and system of thermal control of the resource of protective properties of installations used for air regeneration in enclosed spaces are considered. The main components of the installations are КО2-based chemical sorbents deposited on inert fibrous materials, which absorb carbon dioxide and water vapor released during breathing as a result of an exothermic reaction and enrich the air with oxygen. The method involves measuring the temperatures of the surfaces of regenerative elements (chemisorbents in the form of plates) and the power of an additionally used flat heating element, the temperature of which is controlled equal to the temperature of the chemisorbent. According to the measurement results, two dimensionless parameters are calculated, depending on the power and temperature of the heater, characterizing the life of the protective properties of regenerative elements. Experimental studies of the thermal control method and system were carried out under the following operating conditions of the air regeneration unit: CO2 concentration in the regenerated air 1...4 %, relative humidity 85 ± 10 %, air temperature 20 ± 5 ºС. The ranges of values of dimensionless parameters used in the proposed algorithm for making a decision on the replacement of regenerative elements based on the results of thermal control are found.

Keywords: resource of protective properties, chemosorbent, air regeneration unit, thermal control system.
