Maintaining a standardized microclimate in the poultry house is one of the main factors. It is the quality of the air parameters that ultimately determines the quality of the product output. Poultry at its maintenance requires great efforts and technological solutions. In this regard, the study is to improve the system of microclimate in the air environment of the poultry house by including exhaust fans on the rear end wall in a non-traditional way. Computational Fluid Dynamics (CFD) using ANSYS Fluent is a powerful tool for predicting the microclimate system in the poultry house as an alternative to experimental studies. According to the results of CFD modeling of hydrodynamics and heat and mass transfer processes, it was concluded that changing the spoiler angle by 73° allows to supply air to the center of the house. At the same time the pressure drop at the inlet valves is 70.48 Pa, which allows to fully provide the exhaust fan. The air velocity at the inlet of the supply valves is 11.57 m·s–1. The average air velocity at a height of 0.7 m from floor level is 0.46 m·s–1and the temperature is 15.94 ℃. Thus, the presented scientific research can be used in the future in the development of new ventilation systems of poultry houses.
