Dimensionamento de uma máquina de arrefecimento de Cerveja utilizando células Peltier

Abstract

The present work aimed at the design of a beer cooling machine using Peltier cells. The methodology included the study of heat transfer fundamentals, the sizing of components such as coil, fins and reservoir, as well as the use of numerical simulations to predict the system’s thermal behaviour. The cooling times of water and beer were evaluated, together with the thermal efficiency of the system and the economic assessment of the proposed solution. Results show that the machine reaches 2 °C in 31 minutes for water and allows cooling beer from 37 °C to 4 °C in only 2 minutes per serving, confirming both the technical and economic feasibility of the design.
