METHOD FOR COOLING RESPIRATORY GAS MIXTURE IN RESPIRATORY INDIVIDUAL PROTECTIVE EQUIPMENT Russian patent published in 2017 - IPC A62B7/08 

FIELD: chemistry.

SUBSTANCE: respiratory gas mixture (RGM) is passed between fibrous supporting structures on which a coolant is preliminarily applied to one or both sides, while as coolant the mixture of solid high molecular saturated hydrocarbons modified by nanomaterial is used. The mixture of modified parafins with different phase transition temperature is used as the coolant. As a nanomaterial, carbon nanostructured material "Taunit" is used, which is the mixture of carbon nanotubes of "Taunit" or "Taunit-M" type in the quantity (wt.%) from 0.5 to 10, or nanographite (polygraphene) in the quantity (wt.%) from 0.2 to 6 is used. Nodeless net is placed into a gap between fibrous supporting structures with applied coolant. The use of claimed method allows to enhance RGM cooling efficiency by 25-40°C for generation comfort respiration conditions.

EFFECT: simpler servicing of respiratory protective equipment and providing the possibility of long-term storage thereof in live condition.
