dc.description.abstractModern systems for cooling the supply air in poultry houses are based on the use of spraying or evaporative systems. Both systems rely on the principle of adiabatic cooling, where water transitions from a liquid to a gaseous state through free evaporation, allowing for the reduction of the temperature of the external heated air in poultry premises. The objective of the research study was development of theoretical basis for using new method of cooling the outside air in poultry house ventilation systems is proposed, based on the use of water from underground wells and recuperative heat exchangers to cool the supply air. This method enables the reduction of the outside air temperature without increasing its relative humidity, unlike water spraying cooling systems, for example. Numerical modeling was conducted to obtain velocity fields, temperatures, and pressure differentials in the air environment of the poultry house. The results show that the air temperature exiting the heat exchangers at 20 °C is heated up to 26.6 °C inside the poultry house. Thus, the temperature of the supply air with this cooling system does not exceed permissible norms. The velocities and pressure differentials are sufficient to ensure that the air exiting the supply valves reaches the middle of the poultry house.eng
