Water evaporators are used to cool the air in poultry buildings during hot climates. However, these devices can not provide even, equal and efficient distribution of the cooled air. Thus, the investigation of air coolers with a great cooling depth becomes important. In this regard, the research aimed to theoretically and experimentally establish a more rational cooling depth and cooling efficiency for air coolers. The object of the study was a device with a capillary porous plate having evaporator sockets. Balance equations and mathematical modeling were used as a methodological base. The analysis of microclimate parameters showed that the use of the moistening system significantly improved the microclimate in the building under study. Thus, the air temperature decreased by 1-20C and humidity increased by 6.5%. The results of the study showed that the air-conditioning system had the necessary efficiency and was able to meet the normative parameters of the microclimate during the last critical stage of broiler breeding. The average live weight was slightly higher under the humid conditions, with 2 kg of feed savings per 1 kg live weight gain. The total fodder saving was 1.5 tonnes during the breeding of this experimental batch.
