| Popis: | This work proposes a modeling for the thermal behavior of piglets' house, based on innovative alternatives material and sustainable production systems. The applied finite difference method is applied for the solid system up to the floor and the finite volume method is applied in the piglets' house using the CFD toolbox Open FOAM. Both models simulate each temperature value inside the shelter in order to adjust the thermal floors heating parameters convenient for an optimum animal welfare. The cement based floors were fabricated applying residual materials: swine deep bedding ashes and short sisal fibers. The correlation between modeled and experimental values is satisfactory (standard deviation of 1.37 K for the floor temperature determination and 0.56 K for the black globe temperature determination). The temperature of external environment and inside the piglets' house are effective to adjust the temperature of the electrical resistance of the thermal floor for better performance of the piglets’ microenvironment. |
