Efeito da cobertura e envoltório no consumo de energia elétrica em aviários de frango de corte

Abstract

This study aims to evaluate the impact of different covers and closures of aviaries in the electric energy consumption in these production systems. For this evaluation were selected two aviaries in the dark house type installed in the Western region of Paraná State, the first with a composite material by aluzinc on the upper side with a layer of polyurethane and aluminized film in the lower side, and the second with aluzinc covering with canvas lining, canvas side fence. The two aviaries have dimension of 16x150 meters with approximately 14 chickens per square metre. For the evaluation of temperature and relative humidity inside and outside of the aviaries was used a thermo-hygrometer, while for the evaluation of the surface temperature of the birds was used a thermal imager camera and the electric energy consumption was obtained by through an energy analyzer. So, the effect of thermal comfort on aviaries on birds and the differences in energy consumption in the two aviaries were evaluated. Thus, it was observed that the aviary A1, with thermal insulation on the roof, presented values for internal average temperature, internal average relative humidity and temperature of the bird closest to those considered as ideal, and it was also the aviary A1 that presented lower value for the consumption of electricity registered for the period of seven days during the accommodation.
