Resumo: High temperature associated with open typology and lack of thermal isolation of animal sheds seriously affects productive performance of animals. Generally, in Brazil the cooling systems are based on evaporative adiabatic cooling processes with humid porous material pads associated with ventilation systems in tunnel mode. This study compares the efficiency of porous pads made from expanded clay (cinasita) or from cellulose pads (control). Pads of 60, 85 or 100 mm thickness, and two granulometries (grit 1 or grit 2) were used for all temperatures and airflow speeds. The results were analyzed according to hypothesis test of two means. The grit-1 pads were found to be most efficient. The 100 mm grit-2 pads also showed good performance.

Neste sentido, os sistemas de acondicionamento de ambientes usuais nas atividades de produção animal brasileira geralmente fazem uso de processos de resfriamento adiabático evaporativo do ar, utilizando painéis de material poroso umedecido, associado aos sistemas de ventilação em modo túnel. Diante do exposto, este trabalho teve como objetivo comparar a eficiência de placas porosas em argila expandida (cinasita) em relação às do painel de celulose (testemunha) para todas as condições de temperaturas e velocidades das correntes de ar. Foram usados painéis em três espessuras (6 cm, 8,5 cm e 10 cm) e em duas granulometrias, denominadas de granulometria 1 (referência à brita 1) e granulometria 2 (referência à brita 2). Os resultados obtidos foram interpretados com testes de hipóteses de duas médias. Foram encontrados melhores valores de eficiência para os painéis em granulometria 1 em relação à granulometria 2. Também foi verificado bom desempenho para o painel evaporativo de 10 cm de espessura quando a granulometria da argila era a 2.Universidade Federal de Viçosa - UFV2011-12-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/9610.13083/reveng.v19i6.107Engineering in Agriculture; Vol. 19 No. 6 (2011); 516-523Revista Engenharia na Agricultura - REVENG; v. 19 n. 6 (2011); 516-5232175-68131414-398410.13083/reveng.v19i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/96/80Rosa, José FranciscoTinôco, Ilda de FátimaFernandes, Carlos MagnoZolnier, SergioBueno, Mateus Marquesinfo:eu-repo/semantics/openAccess2023-01-19T12:59:50Zoai:ojs.periodicos.ufv.br:article/96Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:59:50Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
