Title: Evaporative Cooling In Tropical Climate: Case Study Of Campinas, Brazil
Author: Teixeira C.F.B.
Labaki L.C.
Abstract: In Brazil, a country with great territorial extension, a major extension of the territory is in tropical climate. So the challenge for researchers and designers is to achieve comfortable indoor temperatures and to contribute to energy saving. The objective of this paper is to present a discussion about the results obtained in a case study accomplished in cell-tests with roof evaporative cooling in Campinas, SP. Comparative monitoring of surface internal temperature of roof tiles, simultaneously with and without water spraying at different time intervals, as well as attic air temperatures of corresponding cell-tests are presented. The technique allowed verifying a significant difference in the tile surface internal temperature, even when water spraying occurred in small time intervals. Results show that evaporative cooling in fiber-cement tiles for heat attenuation with reduced time intervals of water spraying, even in season with high relative humidity could be a passive cooling technique for low-income housing, for which those tiles are frequently the only roof component.
