Desenvolvimento de um equipamento para refrigeração de latas

Abstract

This work presents the development of a device that performs the cooling of a beverage can, with a volume of 350mL, from a room temperature to an approximate value of 3°C, in about one minute. The equipment has as premises the use of Peltier cells to take out the heat of the system and the use of water to perform the heat exchange between the Peltier and the beverage can. It shows some construction details of the project as the structure of the equipment, how the cooling happens and how the heat is removed from the system. It shows the accumulated thermal energy calculations in the beverage can and discusses the forms of heat transfer, which occur during the operation of equipment, in order to remove this accumulated energy. Besides that, with the thermal energy calculations determines how many cells are enough to supply the power rating to the system. Show details about how the supply of electrical power occurs to the system and the electrical circuits for operating, starting by the rectifier that is the input system of the equipment, followed by the converter, to control the electrical power, till the filters used in order to get an electrical power of quality. At the end, presents the device used to perform the control of the energy that is transferred to the system, and a quickly review of the control system operation.
