Dimensionamento de uma câmara frigorífica utilizando materiais de baixo custo

Abstract

This work has as objective to study the use of coconut fiber as a thermal insulator of panels to compose a cold room for cooling beverages in an establishment, from the use of the thermal insulation coefficient of coconut fiber applied to the dimensioning calculations of the chamber. The confirmation of the efficiency of such material as a thermal insulator was based on the comparison of the refrigeration capacity found with that of a cold chamber that uses conventional materials for thermal insulation, such as polystyrene. By the theoretical value found of 0.04 W/m.K, the thermal load of walls, ceiling and floor of 0.65 kW was obtained, which represents an increase of 24% in relation to the same load calculated with the thermal insulation coefficient of Isopor®.
