Resumo: Cellulose pad panels are commonly used in air cooling systems, despite some problems. Several studies have shown the possibility of using alternative materials such as expanded clay (Cinasita). Earlier studies have shown that this type of clay has required characteristics of a good porous material, thus can be an economical replacement for cellulose. The present study was done to determine suitable size and thickness of porous expanded clay pads, which could provide better cooling efficiency in acclimatized environments. Expanded clay pads with granulometry 1 (reference to grit 1) and 77 mm in thickness showed good efficiency for evaporative adiabatic cooling at the wind speed between 0.44 and 1.28 m/s.

Muitos estudos já concluíram que é viável o uso de materiais alternativos diversos em substituição a celulose, entre eles, aparece como viável, a argila. Em pesquisas anteriormente realizadas foi demonstrado que essa argila possui características favoráveis, que satisfazem as exigências pertinentes a um bom material poroso, podendo substituir, com vantagem econômica, a celulose. Diante do exposto, este trabalho teve como objetivo obter um dimensionamento de placas porosas em argila expandida, que permita, por meio de determinada granulometria da argila e uma espessura do painel, no qual se obtenha melhor eficiência de resfriamento do ar, o emprego em acondicionamento de ambientes em geral. Pelos resultados obtidos, pôde-se concluir que os painéis de argila expandida com granulometria 1 (referência à brita 1) e espessura de 7,7 cm foram os que possibilitaram melhor eficiência de resfriamento adiabático evaporativo para qualquer velocidade do ar compreendida entre 0,44 e 1,28 m/s.Universidade Federal de Viçosa - UFV2012-11-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/9710.13083/reveng.v20i5.108Engineering in Agriculture; Vol. 20 No. 5 (2012); 404-411Revista Engenharia na Agricultura - REVENG; v. 20 n. 5 (2012); 404-4112175-68131414-398410.13083/reveng.v20i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/97/81Rosa, José FranciscoTinôco, Ilda de FátimaFernandes, Carlos MagnoZolnier, Sergioinfo:eu-repo/semantics/openAccess2023-01-19T13:03:49Zoai:ojs.periodicos.ufv.br:article/97Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:03:49Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
