The aerodynamic air ducts in the poultry house significantly affect the poultry keeping and ensure air quality. Stagnant zones ultimately worsen the quality of output and many other factors that contribute to this. To improve the aerodynamics in the poultry house, authors proposed to install exhaust ventilation equipment on the upper line – 2.18 m above floor level. New scientific and practical results of CFD modeling show improved aerodynamic characteristics near exhaust fans. On the plane of the room at a height of 0.7 m from the floor level, the average air velocity is 0.696 m/s. In certain areas the air velocity is kept at 1.5 m/s. When the exhaust fans are located on the upper line, the so-called "tunnel effect" is created, which allows, in the warm period of the year, not to use additional equipment of the microclimate system to create a tunnel ventilation system.
