The problems of creating an optimal microclimate in the closed workshops of poultry farms are relevant for the regions of the south of Russia and the Northern Caucasus, especially acute these problems are for Kabardino-Balkaria. The used zoohygienic measures and existing ventilation systems of closed poultry houses need to be improved and adapted to the local natural conditions. The purpose of the work was to research and develop effective ventilation systems for closed poultry houses in hot climates. Existing ventilation systems and zoohygienic conditions in closed-type poultry houses were studied and investigated. According to the results, the main disadvantages of the existing ventilation systems and their low efficiency were established. And on their basis, new technical solutions have been found to create more efficient ventilation systems for closed poultry houses that provide the optimal microclimate: temperature, humidity and pressure. With the active participation of the author, new technical solutions have been developed and proposed, for which two applications for obtaining patents have been prepared: one for a utility model - for a device for moistening and cooling wall ventilation ducts of poultry houses; the second is for the invention - on the method of erecting a cooling system and humidifying the ventilation panels of the supply. During their implementation, these new technical solutions allow creating such a microclimate, thanks to which optimal indicators of productivity and growth, uniformity, efficiency of feed and meat gain are achieved, without reducing the characteristics of the health and well-being of birds. Ventilation is becoming a major factor in microclimate control in closed houses and the epizootological resistance of birds
