Resumo: | A prototype of a dryer with a small capacity heat pump was developed and assembled in the laboratory, for drying thermosensitive products, with a refrigeration system coupled to a thermally insulated chamber, fixed to a single structure. Two options for mounting the heat exchange system inside the drying chamber were tested. In the first option (configuration 1), a configuration with a single heat exchanger was used, which alternated the function of evaporator and condenser, in cooling and heating cycles, through the use of a four-way valve. In the second option (configuration 2), a configuration with two heat exchangers was used, where the air passed first through the evaporator and then through the condenser. The settings were evaluated according to the psychrometric operating conditions: temperature, relative humidity and equilibrium air humidity. Configuration 2 was more effective in conditioning the drying air, with more favorable psychrometric conditions, resulting in lower average equilibrium moisture values. |

Se probaron dos opciones para montar el sistema de intercambio de calor dentro de la cámara de secado. En la primera opción (configuración 1) se utilizó una configuración con un solo intercambiador de calor, que alternaba la función de evaporador y condensador, en los ciclos de enfriamiento y calentamiento, mediante una válvula de cuatro vías. En la segunda opción (configuración 2), trabajamos en una configuración con dos intercambiadores de calor, donde el aire pasa primero por el evaporador y luego por el condensador. Los ajustes se evaluaron de acuerdo con las condiciones operativas psicrométricas: temperatura, humedad relativa y humedad del aire en equilibrio. La configuración 2 fue más efectiva en el acondicionamiento del aire de secado, con condiciones psicrométricas más favorables, lo que resultó en valores promedio de humedad de equilibrio más bajos.Foi desenvolvido e montado em laboratório, um protótipo de secador com bomba de calor de pequena capacidade, para secagem de produtos termossensíveis, com sistema de refrigeração acoplado a uma câmara com isolamento térmico, fixados em uma única estrutura. Foram testadas duas opções de montagem do sistema de troca de calor no interior da câmara de secagem. Na primeira opção (configuração 1), trabalhou-se numa configuração com um único trocador de calor, o qual alternava a função de evaporador e condensador, em ciclos de resfriamento e aquecimento, através do emprego de uma válvula de quatro vias. Na segunda opção (configuração 2), trabalhou-se numa configuração com dois trocadores de calor, onde o ar passava primeiramente pelo evaporador e, depois, pelo condensador. As configurações foram avaliadas segundo as condições psicrométricas de operação: temperatura, umidade relativa e umidade de equilíbrio do ar. A configuração 2 mostrou-se mais efetiva quanto ao condicionamento do ar de secagem, com condições psicrométricas mais favoráveis, resultando em menores valores médios de umidade de equilíbrio.Research, Society and Development2021-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2392910.33448/rsd-v10i16.23929Research, Society and Development; Vol. 10 No. 16; e378101623929Research, Society and Development; Vol. 10 Núm. 16; e378101623929Research, Society and Development; v. 10 n. 16; e3781016239292525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/23929/21025Copyright (c) 2021 Rodrigo Aparecido Jordan; Wellytton Darci Quequeto; Anamari Viegas de Araujo Motomia; Valdiney Cambuy Siqueira; Elton Aparecido Siqueira Martins; Ítalo Sabião Sanches; Édipo Sabião Sanches; Bruno Machado Antuneshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessJordan, Rodrigo AparecidoQuequeto, Wellytton DarciMotomia, Anamari Viegas de Araujo Siqueira, Valdiney CambuyMartins, Elton Aparecido Siqueira Sanches, Ítalo Sabião Sanches, Édipo Sabião Antunes, Bruno Machado 2021-12-20T11:03:07Zoai:ojs.pkp.sfu.ca:article/23929Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:38.973072Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
