Mathematical Modelling of the Hygro-Thermal Regime of a Poultry Livestock Building: Simulation for Spring Climate
(*) Corresponding author
Poultry house are designed to protect chickens, but also to create a suitable climate in order to get a high-level productivity under harsh conditions. This work proposes a mathematical model of the hygro-thermal regime for a poultry livestock building; the particularity of this research is to develop a model related with the age of the broilers and with the air velocity cooling inside the poultry house, furthermore, to determine the convection regime which is most suitable for health and comfort of the chickens. Simulation case studies were conducted to verify and validate the mathematical model where the monitoring control system is used on a 3 different mode controlling: natural mode (natural ventilation), intermediate mode (normal ventilation and consumption of water by the evaporative cooling system) and tunnel mode (maximum ventilation and cooling) and where the chickens are exposed to three different air velocity (0,1-0,3 and 1,2 m/s). The predicted values for internal temperature and relative humidity were tested successfully with the real physical data especially during the first and second age. As good results, the temperature and relative humidity are respectively a root mean-square error (RMSE) of 0,96 °C and 4, 14 %.
