Modern Principles of Air Exchange Concept in Premises of Different Purpose

Abstract:

Modern scientific principles of air exchange and air distribution calculations are meant in the development of calculation methods based on complex consideration of stream flows and approximative models regularity – i.e. system of heat-air balance equations compiled for specific volumes of the premise. The article defines most significant factors affecting the formation of gas, moisture and velocity fields in the premise, namely: heat emission sources, intake streams, descending convective air flows occurring near cold surfaces, heat losses (or intakes), draft ventilation (general exchange and local). Issues regarding determination of intake air volumes and distribution of the above inside the premises were considered in close interrelation with each other (i.e. principle of air exchange and air distribution conjoint calculation). Consistency of calculation methods has been repeatedly proved with physical models and in field conditions.
