Resumo: Solar energy has become the most used forms of alternative energy, being a renewable and non-polluting source. As such, solar heating systems have been increasingly used in the residential and industrial sectors. However, in periods with low or no solar luminosity, its efficiency is impaired. Based on this assumption, this work proposes the mathematical modeling of an auxiliary heating system, using solar energy as an alternative source. Three types of configurations are evaluated for the heating system: system I - without solar collector, system II - with solar collector running 24 hours a day, and system III - hybrid system, in which solar collector is activated only during the period in which there is incidence of solar radiation (10am - 5pm). It is proposed the implementation of on/off and PI controllers, in the configurations studied. The results are obtained from the simulation of the mathematical model using the free software Scilab®. The results show that the hybrid system is saving more energy, about 8% of energy when compared to the system I. The PI control is best suited for this application, especially when it is implemented with hybrid system, saving of 60W of energy per day of operation.

Por lo tanto, los sistemas de calefacción solar se utilizan cada vez más en los sectores residencial e industrial. Sin embargo, en períodos con poca o ninguna luz solar, su eficiencia se ve afectada. En base a esta suposición, el presente trabajo propone el modelado matemático de un sistema auxiliar de calefacción industrial, utilizando la energía solar como fuente alternativa. Se evalúan tres tipos de configuraciones para el sistema de calefacción: sistema I - sin colector solar, sistema II - con colector solar que funciona las 24 horas del día, y sistema III - sistema híbrido, en el que el colector solar se activa solo durante el período en que Hay incidencia de radiación solar (10 am - 5 pm). Para el mejor uso de las fuentes de energía disponibles (renovables y no renovables), se propone implementar controladores on/off y tipo PI, en las configuraciones estudiadas. Los resultados se obtuvieron simulando el modelo matemático usando el software libre Scilab®. El sistema híbrido mostró un mayor ahorro de energía, alrededor del 8%, en comparación con el sistema I. Para los casos que utilizan controladores, en comparación con el sistema sin controlador, el que era más adecuado era el que tenía un controlador PI, con el sistema híbrido. En este caso, se obtuvieron ahorros de 60W de energía per día de operación.A energia solar se tornou uma das formas de energia alternativa mais utilizada, por ser uma fonte renovável e não poluente. Sendo assim, sistemas de aquecimento solar vêm sendo cada vez mais empregados nos setores residenciais e industriais. Todavia, em períodos com baixa ou nenhuma luminosidade solar, a sua eficiência fica prejudicada. Partindo desse pressuposto, o presente trabalho propõe a modelagem matemática de um sistema auxiliar de aquecimento de utilidades industriais, empregando a energia solar como fonte alternativa. Sendo avaliados três tipos de configurações para o sistema de aquecimento: sistema I - sem coletor solar, sistema II - com coletor solar funcionando 24 h por dia, e sistema III - sistema híbrido, no qual coletor solar é acionado apenas durante o período em que há incidência de radiação solar (10h – 17h). Para o melhor aproveitamento das fontes de energia disponíveis (renovável e não renovável) propõe-se a implementação de controladores do tipo on/off e do tipo PI, nas configurações estudadas. O modelo matemático proposto foi simulado usando o software livre Scilab®. Analisando os resultados obtidos pela simulação, o sistema híbrido apresentou maior economia de energia, cerca de 8%, quando comparado ao sistema I. Para os casos utilizando controladores, quando comparados ao sistema sem controlador, aquele que se mostrou mais adequado foi o com controlador PI implementado ao sistema híbrido, apresentando uma economia de 60W de energia, por dia de operação.Research, Society and Development2020-03-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/273010.33448/rsd-v9i3.2730Research, Society and Development; Vol. 9 No. 3; e188932730Research, Society and Development; Vol. 9 Núm. 3; e188932730Research, Society and Development; v. 9 n. 3; e1889327302525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2730/2073Copyright (c) 2019 Silas Tavares Silva, Nádia Guimarães Sousainfo:eu-repo/semantics/openAccessSilva, Silas TavaresSousa, Nádia Guimarães2020-08-20T18:07:57Zoai:ojs.pkp.sfu.ca:article/2730Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:12.519189Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
