METHOD FOR CONTROLLING DEGREE OF ELECTROLYTE DEPLETION IN COMBINED ELECTROCHEMICAL AIR REGENERATION SYSTEMS FOR SUBMARINES Russian patent published in 2013 - IPC A62B11/00 

FIELD: medicine.

SUBSTANCE: invention refers to enclosure air regeneration systems, namely to air regeneration systems for submarines. A method for determining a degree of K₂CO₃ depletion as shown by KOH in the combined electrochemical air regeneration systems for the submarines taking the sea involves continuous or periodic variations of specific electric conductance and temperature of a recycling electrolyte; conversion of the derived values into the KOH concentration in the solution K₂CO₃ and comparison of the derived value to the critical KOH concentration in the solution. A coastal laboratory performs a chemical analysis for the K₂CO₃ content in the electrolyte sampled from the electrochemical regeneration system. The specific electric conductance is measured at the pre-set electrolyte temperature. That is followed by measuring the specific electric conductance of a model electrolyte to be used in the electrochemical regeneration system at the pre-set temperature with the pre-set KOH concentration. In a seaway, the measurements similar to those performed by the coastal laboratory are used in a distribution unit of the electrochemical regeneration system. The current load and electrolyte composition in the electrochemical regeneration system are adjusted on the basis of comparing the measurements in a seaway to those in a coastal laboratory.

EFFECT: developing the air regeneration systems for submarines.
