Investigation of Heat Exchange Processes in a Cooling System in a Poultry House With Side Ventilation

A new method of cooling the outside air in the ventilation systems of poultry houses is proposed, based on the use of water from underground wells and heat exchangers for cooling the supply air. Numerical modeling of aerodynamics and heat transfer processes in poultry houses with a tunnel ventilation system was carried out. As a result of numerical calculations, the distribution of temperatures, velocities, and pressures in the air environment of the poultry house was obtained. The use of heat exchangers to cool the supply air makes it possible to maintain its temperature at +20-25 ℃ and reduce the moisture content in poultry houses, which is high when using cassette methods or spraying water with nozzles to cool the supply air. As a result of the numerical studies, it is recommended to increase air flow rates by including a third exhaust fan located on the top line of the rear end wall. This will allow for a more even temperature distribution in the house.
