Análise das propriedades termofísicas de fluidos secundários para refrigeração. 2020. 28 f. Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica ) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2020.https://repositorio.ufrn.br/handle/123456789/42939This work deals with the analysis of the thermophysical properties of secondary fluids used in refrigeration. The SecCool Properties software was used to simulate and obtain data on the mixture between water and a certain alcohol at different concentration levels. The selected alcohols were ethanol, methanol and propylene glycol for their thermophysical properties, with little or no corrosive effect and being totally soluble in water. The concentration of the solute (the alcohols) was defined between 15% and 45%, in each solution only one solute was used. Tables and graphs were used for better visualization and comparison of the melting point thermophysical properties, specific mass, specific heat, thermal conductivity, dynamic viscosity and kinematic viscosity. The data on the thermophysical properties of the solutions proved to be satisfactory for use in indirect refrigeration systems, with each mixture being applied to specific types of projects, leaving the designer to analyze which solution and in which concentration to use.Propriedades termofísicasThermophysical propertiesFluido secundárioSecondary fluidSoluçãoSolutionResfriamento indiretoIndirect coolingRefrigeraçãoRefrigeration.ÁlcoolAlcoholbachelorThesis
