Item Desenvolvimento de um código computacional para estudo parametrizado da carga térmica de uma câmara frigorífica(2021-03-01) Moreira, José Luciano Batista; Marques, Adriano da Silva; http://lattes.cnpq.br/0104058705628000; http://lattes.cnpq.br/9231432778525972Cold rooms are fundamental equipments for the preservation of perishable foods, guaranteeing the maintenance of the quality of the products in the stages of their processing and distribution. The correct dimensioning of this equipment represents efficiency related to the cooling and freezing performance, as well as the energy efficiency of the system. Thus, this project deals with the development of a computational code on the EES platform (Engineering Equation Solver) to determine the energy consumption of the evaporator unit (thermal load) of a cold room. The cold storage was designed to be installed in the city of Belém do Pará, responsible for storing 5 tons per day of apples and 10 tons per day of pork. The study also presents parameterized results for the thickness of the thermal insulation and the inlet temperature of the products, applying the equations of the thermal load by conduction and the load by the product. The values applied to the parametric variation respect the conditions established by the current technical standards, related to the refrigerated storage of food. It was verified that the discrepancy between the maximum and minimum operation regimes of the cold room, represents a reduction of approximately 20,19% of the energy consumption of the evaporator unit. Thus, it can be concluded that the parameterized study can result in a diagnosis of energy savings for cold storage projects.Item Parametrização da carga térmica de um restaurante através de um código computacional(2022-05-27) Silva, Felipe Mateus Laurentino da; Silva, Rogério Soares da; http://lattes.cnpq.br/5570338185824272; http://lattes.cnpq.br/9299362453501615Refrigeration systems are essential for the thermal comfort of people, in addition to other important existing applications. Correct sizing of air conditioning equipment represents system efficiency and, consequently, better performance. Therefore, this study deals with the development of a computational code in the EES (Engineering Equation Solver) platform to determine the energy consumption of the thermal door of the evaporator units (thermal load) of a fictitious medium-sized restaurant. The restaurant is located in Recife-PE, accepts 250 customers and 17 responsible employees, in addition to indoors. The study also presents the inclusion of a paved surface parking lot and its influence on energy input also through light into the restaurant's interior, in addition to parameterized results of the consequences of the number of people entering the restaurant's interior. From these data, it was possible to observe the customers and resources, through the thermal load of the restaurant, to the point of considering the implementation of the Variable Refrigerant Volume (VRV) system at the point of reflection of the thermal load. The script used for the human comfort of load obeyed as current norms, related to systems that aim at the thermal in closed places. It was verified that the inclusion of a paved surface parking lot increases by 900% the insolation values for the interior of the restaurant. In this way, it is concluded that the computational study can result in a more real and reliable car system to the demand of the establishment.
