Resumo: Roof coverings are responsible for promoting a suitable environment for animal production, in addition to be one of the main factors interfering with heat transfer. In this context, this study aimed to assess different roof covers over reduced-scale shed prototypes through thermography. The experimental design was completely randomized with five treatments (TT, thermal; RT, recycled (Tetra Pak); ACT, asbestos-cement; BT, bamboo; and AT, aluminum tile) and 14 repetitions, one for each assessment day. For roofing thermal analysis, thermographic images were taken by a thermographic camera (FLIR® TR420), which measured surface temperature changes (external and internal) at 8:00, 10:00, 12:00, 14:00 and 16:00 h, over 14 days. Environmental temperature was measured inside each prototype. BT roofing showed to be efficient, with values of intermediate surface temperatures, enabling its use in replacing RT, AcT and AT roofing tiles. These other tiles had no difference from each other and showed the worst performances.

Nesse contexto, objetivou-se avaliar através da termografia, o desempenho de diferentes coberturas em modelos reduzidos de galpões. O delineamento adotado foi inteiramente casualizado com cinco tratamentos, sendo diferentes tipos de coberturas: TER - Térmica; REC – Reciclada (Tetra-Pak); CIA – Cimento-amianto; BAM – Bambu e ALU – Alumínio, com 14 repetições, referentes aos dias de coleta. Para a análise térmica dos materiais de cobertura foram utilizadas imagens termográficas utilizando-se uma câmera termográfica TR420, da FLIR, que mensurou a variação das temperaturas superficiais (externa e interna) registradas nos horários das 8, 10, 12, 14 e 16 h, no período de 14 dias experimentais. Foi coletada a temperatura ambiente no interior de cada modelo reduzido. A cobertura de bambu mostrou-se eficiente, apresentando valores de temperaturas superficiais intermediários, o que possibilita seu uso em substituição às telhas reciclada, cimento amianto e alumínio, as quais não diferiram entre si e apresentaram os piores desempenhos.Sociedade de Ciências Agrárias de Portugal2019-01-14T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/RCA17215eng2183-041X0871-018XAkamine, Luana AlvesAraujo, Kari Katiele SouzaSena, Carolina CarvalhoPassini, Robertainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:24:45Zoai:ojs.revistas.rcaap.pt:article/16651Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:31:01.190739Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
