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 wall ventilation panels of closed house housings includes a pipe with holes for water supply from the top of the panel and water collectors at the bottom. On top of ventilation panels there passes horizontally pressure polymer pipe with atomisers for water spraying in two pieces above each ventilation panel. Ventilation panels are made of geonet and facades, which are put on air intake grids. At the bottom of the panel along a line of window ledges with a slope a non-pressure water collecting pipe is stretched from polymer material with diameter not less than thickness of panels. At the same time sections of pipe passing under panels within their width are made with cutout to the middle of pipe, on top of which along the entire area of cuts a mesh from stainless material is attached.EFFECT: invention provides higher efficiency of house ventilation system due to effective cooling and moistening of inlet warm and dry air and creation of normal microclimate inside closed premises of poultry houses in summer heat, as well as reduction of material costs for its installation.1 cl, 5 dwgИзобретение относится к системам вентиляции птицеводческих ферм и может быть использовано для обеспечения циркуляции охлажденного воздуха в закрытых птицефабриках. Система увлажнения и охлаждения пристенных вентиляционных панелей закрытых птичников включает трубу с отверстиями для подачи воды сверху панели и водосборники внизу. Сверху вентиляционных панелей горизонтально проходит напорная полимерная труба с форсунками для распыления воды по две штуки над каждой вентиляционной панелью. Вентиляционные панели выполнены из геосетки и фашин, которые ставят на решетки приточных окон. Внизу панели по линии подоконников с уклоном протягивается безнапорная во
