Resumo: The thermal environment inside a broiler house has a great influence on animal welfare and productivity during the production phase. Enthalpy is a thermodynamic property that has been proposed to evaluate the internal broiler house environment, for being an indicator of the amount of energy contained in a mixture of water vapor and dry air. Therefore, this study aimed to characterize the spatial variability of enthalpy in a broiler house during the heating phase using geostatistics. The experiment was conducted in the spring season, in a commercial broiler house with heating system consisting of two furnaces that heat the air indirectly, in the first 14 days of the birds' life. It was possible to characterize enthalpy variability using geostatistical techniques, which allowed observing the spatial dependence through kriging maps. The analyses of the maps allowed observing problems in the heating system in regions inside the broiler house, which may cause a thermal discomfort to the animals besides productive and economic losses.

A entalpia é uma propriedade termodinâmica que tem sido proposta para avaliação do ambiente interno de galpões de criação de frangos de corte por ser um indicador da quantidade de energia contida em uma mistura de vapor d'água e ar seco razão por que se objetivou, com o presente trabalho, caracterizar a variabilidade espacial da entalpia em um galpão de frangos durante a fase de aquecimento de pintinhos utilizando a geoestatística. O experimento foi conduzido na primavera, em um galpão comercial com sistema de aquecimento constituído de duas fornalhas de aquecimento indireto do ar, durante os primeiros 14 dias de vida das aves. Utilizando as técnicas da geoestatística foi possível caracterizar a magnitude da variabilidade espacial da entalpia permitindo a observação da dependência espacial por meio de mapas de krigagem. A análise dos mapas permitiu observar a existência de falhas no sistema de aquecimento em regiões do galpão, que podem ser possíveis causadoras de desconforto térmico para os animais, além de perdas produtivas e econômicas.Universidade Federal de Campina Grande (UFCG)2018-07-18T20:31:11Z2018-07-18T20:31:11Z2016-04-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFERRAZ, P.
