Air movement characteristics inside a cow barn with natural ventilation under no-wind conditions in the winter season

The paper presents results of air movement observations inside a cow barn (Fermbet construction type) adapted for a loose housing system. The conducted experiments made it possible to determine directions and characteristics of ventilated air flux in selected areas of the building as well as mark out areas where air stood still. In addition, the study offers recommendations regarding effective ventilation systems in the occupied zone under no-wind conditions.
