One of the reserves of animal husbandry intensification is normalization of air environment of livestock breeding and poultry breeding farms. Optimization of microclimate allows achieving physiological potential of productivity of animals and birds. Normal air environment also promotes reliability of the equipment. Worsening of microclimate leads to decline of animal productivity and increase of fodder consumption per one unit of production. For creation of controlled air exchange inside the farm room special inflow and outflow devices are used. Air chambers with regulated air gates supply air inflow and outflow, but they accumulate condensed vapor on their walls because of temperature difference. Therefore, creation of rational construction of inflow-outflow device with regulation of air distribution appears quite important problem. A special research of inflow cold proof air chamber with air distribution is carried out. A scheme of an experimental air chamber with special ring and disc is presented. A scheme of inflow cold proof air chamber with air distributor is displayed. Physical characteristics of the both chambers are enumerated. Dependence of air movement speed inside the chamber on different work regimes is shown; dependence of productivity of the chamber on different work regimes is evaluated. Energy consumption of ventilators during different work regimes is presented.
