RESUMO

In this paper, a new type of metal roof-pond based on indirect evaporative cooling and including confined thermal mass is experimentally evaluated. Five passive cooling systems have been studied with this experimental device. Their characteristic temperatures are analyzed in order to determine the cooling potential in each case and the influence of the thermal mass on thermal performance. The passive cooling techniques applied include indirect evaporative cooling (EEI) and nocturnal radiative cooling (ER). The system that combines thermal mass and indirect evaporative cooling in the experimental device presents high cooling efficiency; its value increases as the conditions become more extreme. A greater cooling potential is achieved by adding radiative cooling to the previous system.
