REFRIGERADOR PORTÁTIL ALIMENTADO POR ENERGIA RENOVÁVEL

Abstract

This study is about the design of a portable refrigerator powered by renewable energy. Research is done on small scale solar and wind energy availability. The refrigeration is generated by thermoelectric modules, also known as Peltier modules. A successful refrigeration project begins with the correct calculation of the heating load. These calculations are based on local data from the intended area of operation (Tramandaí). The Peltier module selection is done through a heat transfer analysis based on the heat sinks used on the design and using the datasheet provided by the module manufacturer. The software EnergyPlus is used to calculate the available power provided by the photovoltaic panel during operation. Finally a brief study about the system electric components is done and its connections are represented in a simplified drawing. The design of the portable refrigerator has some physical and energetic constraints, like the large size and weight of its components, great energy consume by the Peltier modules and the low rate of energy powered by the renewable sources, adding a limitation to the heating. However, when the product is placed at 5 °C in the refrigerator, the temperature is preserved, and the refrigerator works within its limitations energy.
