Resumo: | Tests were carried out in an open environment with two photovoltaic panels, in the city of Dourados/MS, for six non-consecutive days, between the months of June to July 2018, where one panel was kept original (PV), while the other underwent modifications to operate as a photovoltaic-thermal module using (PVT/w), which is connected to a reservoir for hot water accumulation. The tests were carried out according to the open circuit voltage (Voc), the surface temperature of the photovoltaic cells and the water temperature of the cooling and thermoaccumulation system of the PVT/w, to determine the adequate and adequate thermal energy of the thermal yield. The increase in the temperature of the cooling water negatively affects the value of the open circuit voltage, which was, on average, 2.3% higher for PVT/w, which presented a lower surface temperature in all tests. The average thermal efficiency of PVT/w was 242 W m-2, given in an estimate of total efficiency (thermal and electrical) of 349 W m-2, an increase of 161% in relation to the energy efficiency of PV (only electricity), estimated at 106 W m-2 based on information from the manufacturer's technical catalog. |

Las pruebas se realizaron en función de la tensión en circuito abierto (Voc), la temperatura superficial de las células fotovoltaicas y la temperatura del agua del sistema de refrigeración y termoacumulación del PVT / w, para determinar la energía térmica adecuada y adecuada del rendimiento térmico. El aumento de la temperatura del agua de refrigeración incide negativamente en el valor de la tensión de circuito abierto, que fue, en promedio, un 2,3% superior para PVT / w, que presentó una temperatura superficial más baja en todas las pruebas. La eficiencia térmica promedio de PVT / w fue de 242 W m-2, dada en una estimación de eficiencia total (térmica y eléctrica) de 349 W m-2, un aumento del 161% en relación a la eficiencia energética de PV (solo electricidad), estimado en 106 W m-2 según información del catálogo técnico del fabricante. Foram realizados testes em ambiente aberto com dois painéis fotovoltaicos, na cidade de Dourados/MS, durante seis dias não consecutivos, entre os meses de junho a julho de 2018, onde um painel foi mantido original (PV), enquanto o outro sofreu modificações para operar como um módulo fotovoltaico-térmico utilizando água (PVT/w), sendo este conectado a um reservatório para acumulação de água quente. Nos ensaios foram feitas medições de tensão de circuito aberto (Voc), temperatura na superfície das células fotovoltaicas e temperatura da água do sistema de resfriamento e termoacumulação do PVT/w, para determinação da energia térmica produzida e estimativa do rendimento térmico. O aumento da temperatura da água de arrefecimento afeta de forma negativa o valor da tensão de circuito aberto, a qual foi, em média, 2,3% maior para o PVT/w, o qual apresentou menor temperatura superficial em todos os testes. O rendimento térmico médio do PVT/w foi de 242 W m-2, resultando numa estimativa de rendimento total (térmico e elétrico) de 349 W m-2, um aumento de 161% em relação ao rendimento energético do PV (apenas energia elétrica), estimada em 106 W m-2 com base nas informações do catálogo técnico do fabricante.Research, Society and Development2021-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1643810.33448/rsd-v10i7.16438Research, Society and Development; Vol. 10 No. 7; e14210716438Research, Society and Development; Vol. 10 Núm. 7; e14210716438Research, Society and Development; v. 10 n. 7; e142107164382525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16438/15161Copyright (c) 2021 Rodrigo Aparecido Jordan; Orlando Moreira Junior; Bruno Machado Antunes; Anamari Viegas de Araujo Motomiya; Ítalo Sabião Sanches; Édipo Sabião Sanches; Agleison Ramos Omido; Elton Aparecido Siqueira Martinshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessJordan, Rodrigo AparecidoMoreira Junior, Orlando Antunes, Bruno MachadoMotomiya, Anamari Viegas de Araujo Sanches, Ítalo SabiãoSanches, Édipo Sabião Omido, Agleison Ramos Martins, Elton Aparecido Siqueira 2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16438Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:59.320304Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
