Annotation

The microclimate of livestock facilities is determined by a range of factors, including physical parameters: humidity, atmospheric pressure, light, temperature, speed and direction of air movement. Air quality plays an important role - the concentration of harmful gases and microorganisms, dust. The parameters of the microclimate affect not only the productivity of animals, but also their health. In order not to harm the health of the animal and achieve the desired performance, these parameters must be adjusted with special equipment. The purpose of research is to substantiate the design and technological parameters of the ventilation system for the injection of clean air in livestock premises to ensure uniformity of its distribution. The article presents the results of research to substantiate the design and technological parameters of the ventilation system for the injection of clean air in pig farms to ensure uniformity of its distribution. As a result of analytical studies of the parameters of the slit of the nozzle for air injection from the condition of uniform air distribution, an approximate equation for its width δ'y depending on the y-axis location for different effective diameters of the nozzle d'H. For the system of injection of clean air the condition according to which at opening of all discharge valves it is necessary to provide uniformity of distribution of air by system of injection is set. For this purpose the central air duct for air injection should have a wedge-shaped form of length L' with constant height b', with initial width a'N and final a'1. As a result of theoretical researches dependences of a lateral angle of a wedge θ the central air duct of system of injection of pure air and its width on the end a1' on distance between adjacent sections L'0, width of the central air duct on its beginning aN' and quantity of branch pipes for injection N' are established. As a result of analytical studies of pressure losses of the ventilation system of pure air injection of the pigsty, the dependences of changes in pressure losses Δp2 and power NW2 required for pumping air through it on the width of the central air duct aN, air flow through the system qk, length between system pipes L0 and their number N.

Keywords: livestock premises, microclimate, equipment, ventilation, injection, air duct, uniformity parameters.
