Avaliação de ambiente térmico de galpões com e sem isolamento térmico para poedeiras comerciais

Abstract

The concern about the constructive aspects of the zootechnic installations has increased in order to provide an adequate environment, thermal comfort and consequently, comfort for the animals. Between these aspects, the thermal insulants are responsible to reduce the heat flow emitted on the roof during the hotter hours of the day. In order to prove it, heat and humidity sensors were installed in three different heights inside the corridors of two poultry sheds that are located in Mantiqueira’s farm in the city of Primavera do Leste- MT. One of the sheds uses extruded polystyrene (FOAMULAR®) installed in its structure as an insulant material. After the statistic comparation of the data, the results reveal a significative difference of the temperature obtained by the higher height sensors and the medium height sensors of the sheds, especially during the hours of higher solar radiation. The sensors localized in the lower height of both sheds did not obtain a significative difference in the temperature because they are localized under the nebulizers. Through the comparison of the data obtained, it is possible to conclude that the insulant material has contributed to the efficiency of the thermal comfort of the animals, being a good option for use in installations
