Análise do comportamento térmico do forro de resíduo de composto EVA + SBR em habitação de interesse social na cidade de Campina Grande-PB.

Abstract

This work had as general objective to evaluate the thermal behavior of the ceiling of the Copolymer compound (Ethylene-Vinyl Acetate) - EVA + Copolymer (Styrene) Butadiene) - SBR, in buildings of social interest. The research was carried out in a reduced model of a housing block, which contains four housing units (two storeys and two on the upper floor). Such a model was produced in a geometrically similar class, on a scale of 1: 5, structured in sheets plywood, covered with asbestos cement tile. The collection of data was made in the four units, one on the upper floor, one with the ceiling (CF) and one without a ceiling (SF). Data were recorded both in the cold and in the hot, 45 days with the model in the North-South direction and 45 days with the model in the East-West direction, at intervals of every twenty minutes, with the sensors inside and on the cover of the model. The T-type thermocouple wire data referring to the following variables: temperature of the upper surface of the tile (SST), lower tile surface temperature (SIT), surface temperature upper lining (SSF), lower lining surface temperature (SIF), dry bulb (room temperature), wet bulb and black globe. Based on the data collected, the behavior of the environment was determined inside the reduced models CF and SF, with the help of the following indices: temperature and humidity index (ITU) and wet bulb index and globe temperature (IBUTG). Under the conditions in which this work was carried out, and with the results obtained, it is concluded that the presence of the of the compound in question provides thermal comfort in residential buildings of social interest, reducing the temperature of the environment in the most critical periods of heat and keeping the environment warm for longer, in the coldest periods.
