Tecnologias de arrefecimento térmico em telhados para condicionamento ambiental

Abstract

This research presents the study on evaporative cooling, by water sprinkling on roofs, in the bioclimatic zone 2. Constructive solutions of roofs that allowed the improvement of the environmental conditions of comfort in buildings confined environments were prospected. The solutions were prototyped through six test cells covered with aluzinco tiles, fiber cement and glass. Based on the equations of NBR 15220-2003, the parameters of the test cell were modeled as: thermal resistance and termal transmittance. Through the test cells, two non-cooling roofing conditions were tested in the asbestoscement, alloy-cement and cooling models in the asbestos, alloy and glass models, both of which demonstrated improved ambient conditions.
