STUDY OF THE INFLUENCE OF THE ARRANGEMENT OF EXHAUST FANS ALONG THE LOWER LINE ON THE AERODYNAMICS OF THE POULTRY HOUSE

Abstract

Coverage and outbreaks of diseases lead to considerable losses in large-scale poultry farming. New ventilation systems are essential to ensure a safe and uniform indoor environment in large enterprises, especially in the changing climate of global warming. Thus, it is necessary to improve the design of the poultry house, to search for the most effective way of arranging the supply air valves and to improve the aerodynamic parameters of the internal environment of the poultry house in the most effective way of arranging the supply air valves and improving the aerodynamic parameters of the internal environment of the poultry house. Within the framework of this study, computational hydrodynamics modelling of the lateral ventilation system in the poultry house during the winter period of the year was performed. As a result, the temperature of the 3D field, the current lines, and the pressure in the aviary were detected. Supply air valves located 200 mm above the floor were found to perform better than those conventionally installed at 400 mm. Building walls on the inside of the poultry house frame, as well as reducing the height of the floor, improve the aerodynamics of the poultry house. The practical value of the presented study is targeted at poultry farmers with large productive capacities.
