ADSORPTIVE DRYING OF RETURN AIR IN SPECIAL-PURPOSE ROOMS AS A MEANS OF BETTER PERFORMANCE OF BUILDING STRUCTURES IN DAMP

A scientifically verified energy saving device has been designed to produce compressed air in damp environments in order to improve the reliability of building structures used in special-purpose rooms like heat chambers for testing electronic components. The devices operation involves the treatment of intake atmospheric air in the compressor air filter by utilizing turbulence and thermodynamic separation phenomena, which makes the cleaning from fine-dispersed particles and water drops more intensive. Further on the treated air is subjected to adsorption drying until rated parameters of return air are reached up both in terms of temperature and cleanness. The paper develops the theory of added masses by supplementing the definition of kinetic energy with atmospheric air stream that is saturated by airborne contamination particles (natural and man-made dust particles) before constriction section, and that makes it possible to determine a jump in the stream speed with subsequent release of friction heat. The identified phenomenon was proved experimentally with reference to the theory of intake air thermodynamic laying in the vortex cavity of the compressor air filter. The disagreement between expected temperature drop in the “cold” stream with actual parameter value is within correlation error range and is related with steam specific enthalpy that depends on climate and weather conditions on construction or quarry site. The original design solution is protected by RF patent.
