FIELD: ventilation and air conditioning； poultry breeding.SUBSTANCE: invention relates to poultry farming ventilation systems and can be used to provide circulation of cooled air in closed poultry farms. System for humidification and cooling of inlet ventilation panels of air-supply windows of houses includes a pipe with holes for water supply from the top of the panel and water collectors at the bottom. Pressure polymer piping with stiffness rings around pipe at a distance of width of ventilation openings and panels horizontally passes from above ventilation cassettes. Pipe sections on top of the panels between the stiffening rings are perforated, around the windings by geomats. Ventilation panels are made of geonet and fascines of bulrush attached to it, and fixed on air inlet grids. Non-pressure water collecting pipe of polymer material with diameter not less than thickness of panels is stretched along the window ledges with slope. At that, pipe sections passing under panels within their width are made with cutout to the middle of the pipe, on top of which along the whole area of cuts there are mesh made of stainless material.EFFECT: invention provides higher efficiency of house ventilation system due to effective cooling and moistening of inlet warm and dry air, creation of normal microclimate inside closed workshops of hen houses in summer heat, as well as reduction of material costs for its installation.1 cl, 6 dwgИзобретение относится к системам вентиляции птицеводческих ферм и может быть использовано для обеспечения циркуляции охлажденного воздуха в закрытых птицефабриках. Система увлажнения и охлаждения приточных вентиляционных панелей приточных окон птичников включает трубу с отверстиями для подачи воды сверху панели и водосборники внизу. Сверху вентиляционных кассет горизонтально проходит напорная полимерная труба с кольцами жесткости вокруг трубы на расстоянии ширины вентиляционных окон и панелей.
