Avaliação do uso das embalagens de caixa Tetra Park para aumento do conforto térmico de paredes de alvenaria no sertão alagoano

Abstract

This work presents the study of plates produced from the junction of Tetra Pak boxes, cut and washed, with the objective of reusing them as thermal insulation in masonry walls, with different materials, in Sertão Alagoano. The plates were made by gluing with the heating of an electric iron. After that, they were installed as a thermal insulator on two small walls, one made of concrete block with an area of 0,32 m2 and the other of soil-cement with expanded clay with an area of 0,204 m2. A second experiment was carried out in the drivers' break room at UFAL - Campus Sertão, where two plates were installed, one with an area of 6,7 m2 and the other smaller, with an area of 0,57 m2. In addition, a third step was carried out: the simulation of a model similar to the conditions of the drivers' break room, in the fluid dynamics software: ANSYS WORKBENCH and, comparing the results obtained with the experimental results for the reliability of the values. With the analysis of the experiments and the simulation, it was observed that the Tetra Pak milk cartons have an insulating material behavior, thus being able to be used for thermal comfort purposes in masonry walls in semi-arid regions.
