Simulação computacional para o desempenho térmico de paredes trompe para a cidade de São Luís

Abstract

The present research aims to investigate the use of Paredes Trombe in the city of São Luís to promote thermal comfort. The method used to investigate and analyze the results was the Finite Differences Method used in Heat Transfer analysis. It was necessary to collect data on air temperatures and solar radiation of four periods of the seasons of 2016: autumn equinox, winter solstice, spring equinox and summer solstice. As well as the use of information regarding the initial thickness of the Wall Trombe, taking into account the reality of the city buildings, coefficient of thermal conductivity, convection coefficient of internal and external air and internal design temperature, information obtained by queries in standards Regulatory and technical catalogs. After analyzing the graphical results, it was verified that the use of this technology for the city of São Luís would not be technically feasible from the point of view of thermal comfort, but with the increase of the Wall Trombe thickness (increase of the Thermal Inertia of the Wall Trombe) The results tend to approach a more viable thermal reality, that is, to get closer to the comfort temperature
