Resumo: In order to improve the thermal condition inside built environments and consequently to reduce the consumption of electricity, the Earth-Air Heat Exchanger (EAHE) is a device that uses renewable energy from the solar radiation that reaches the soil surface and is deposited in the form of thermal energy. Its operating principle consists of forcing the ambient air to flow inside one or more ducts buried in the ground, which due to its thermal inertia allows the heat exchange with the flowing air. In this way, the soil removes heat from the air in seasons of higher temperatures, and provides heat to the air in seasons of the year when temperatures are lower. Thus, this work has the objective of analyzing numerically the thermal behavior of an EAHE installation, considering the soil of a region of the Federal University of Rio Grande (FURG), as well as the realistic annual temperature variation of air and surface for this region. Through a validated and verified computational model, numerical simulations were performed in Fluent software (based on the Finite Volume Method). The results indicated that the ideal installation depth for the EAHE is 2.00 m, with thermal potential for improving the thermal condition of environments built in both summer and winter.

Seu princípio de funcionamento consiste em forçar o ar ambiente a escoar no interior de um ou mais dutos enterrados no solo, que devido a sua inércia térmica permite a troca de calor com o ar em escoamento. Dessa forma, o solo retira calor do ar em estações do ano de temperaturas mais elevadas, e cede calor ao ar em estações do ano em que as temperaturas são mais baixas. Sendo assim, este trabalho tem o objetivo de analisar numericamente o comportamento térmico de uma instalação de TCSA, considerando o solo de uma região da Universidade Federal do Rio Grande (FURG), bem como a variação anual realística de temperatura do ar e da superfície do solo dessa mesma região. Através de um modelo computacional, validado e verificado, foram realizadas simulações numéricas no software Fluent (baseado no Método dos Volumes Finitos). Os resultados apontaram que a profundidade de instalação ideal para o TCSA é de 2,00 m, existindo potencial térmico para melhoria da condição térmica de ambientes construídos tanto no verão quanto no inverno.Programa de Pós-Graduação em Integridade de Materiais da Engenharia2019-01-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/ripe/article/view/1921610.26512/ripe.v5i1.19216Revista Interdisciplinar de Pesquisa em Engenharia; Vol. 5 No. 1 (2019): Revista Interdisciplinar de Pesquisa em Engenharia - RIPE; 121-128Revista Interdisciplinar de Pesquisa em Engenharia; v. 5 n. 1 (2019): Revista Interdisciplinar de Pesquisa em Engenharia - RIPE; 121-1282447-610210.26512/ripe.v5i1reponame:Revista Interdisciplinar de Pesquisa em Engenhariainstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/ripe/article/view/19216/20420Copyright (c) 2019 Revista Interdisciplinar de Pesquisa em Engenhariainfo:eu-repo/semantics/openAccessHermes, Vinicius de FreitasCosti, JulianaMarques, Wiliam CorreaRocha, Luiz Alberto OliveiraSantos, Elizaldo Domingues dosRodrigues, Michel KepesIsoldi, Liércio André2019-06-07T22:16:14Zoai:ojs.pkp.sfu.ca:article/19216Revistahttps://periodicos.unb.br/index.php/ripePUBhttps://periodicos.unb.br/index.php/ripe/oaianflor@unb.br2447-61022447-6102opendoar:2019-06-07T22:16:14Revista Interdisciplinar de Pesquisa em Engenharia - Universidade de Brasília (UnB)false
