Методология за адаптивно управление на вентилацията в говедовъдни ферми чрез интегрирана оценка на THI и газови емисии
Methodology for Adaptive Ventilation Control in Cattle Farms Through Integrated Assessment of THI and Gas Emissions

Summary/Abstract: This paper presents a methodology and adaptive algorithm for microclimate management in cattle farms through integrated monitoring of the temperature-humidity index (THI) and air quality (CO₂ and NH₃). The THI is calculated in real time using Thom's formula based on the measured temperature and relative humidity, and on this basis, ventilation modes are determined – from minimum mode under comfortable conditions to maximum ventilation and cyclical activation of sprinklers in case of critical heat stress. At the same time, threshold criteria for CO₂ and NH₃ are applied, which, when exceeded, increase the ventilation power regardless of the THI in order to quickly dilute the harmful gases. The control team is formed according to the strictest criterion, which ensures preventive protection of the animals and sustainable maintenance of a healthy environment in the room
