Desempenho térmico de tipos de coberturas no interior de modelos reduzidos de galpões avícolas

Abstract

The goal of this work was to evaluate the thermal comfort index of reduced scale models (1:10) of poultry houses with different roofing materials. This study was conducted in Central Brazil. Three models of poultry sheds were used with different cover material: ceramic tile, aluminum tile and asphalt, and paper tile (recycled). To analyze the models, information about the dry bulb temperature (Tbs), black globe temperature (BGT), relative humidity (RH) and wind speed (vv), were collected during nine days. The thermal comfort was evaluated and classified through black-globe humidity index (BGHI), thermal heat load (THL), and effectiveness (ε). Average values of 75.65 and 453.09 W.m-2 for BGHI and THL, respectly, were observed in ceramic tile roofing. The results showed that the ceramic tiles provide better thermal environment in reduced scale models of poultry houses.
