We presented an algorithm to predict the temperature-humidity index in a naturally ventilated barn. We found that use of additional accelerating fans reduced the temperature-humidity index in a naturally ventilated barn by 0.4-1.0 units and surface temperature of dairy cows by 0.4-0.5 °C in the hottest period. We also revealed the limitations of suggested model in assessing the effectiveness of additional mechanical ventilation in the barns. Slight decrease of temperature-humidity index in animal keeping area and cooling of cattle body surface should be further enhanced, especially during the heat waves.
