The performance results of Trombe-Wall passive systems under Aegean Sea climatic conditions

Abstract

Since 1977, at the >Solar Energy Thermal Applications Laboratory of M.T.A.> in Marmaris, Turkey, an experimental study of a >Trombe Thermal Storage Wall> passive system continues in operation; two analogous houses have been built, one of which is serving as a reference system. The incident solar radiation on a vertical surface, the temperature changes of the internal and external surfaces of the wall, at interval of thirty minutes, and the convective flow through the >Trombe-Wall> have been measured in order to determine the solar fractions transmitted by the processes of radiation, convection and thermocirculation. In the present study, the variation of the >Trombe-Wall> efficiency has been calculated during the period of a year using a computer evaluation model in which the half hour measurement data have been introduced. The experimental results show that, according to the months, 15-35 per cent of the incident solar radiation over the south facade is transmitted to the interior through the >Trombe-Wall>, while the reference house transmits from the south facade 8-19 per cent of solar radiation received. Finally, it can now be confirmed that the results of the >Trombe-Wall> system without any special type insulation, contributes to practically the total heating load of the village houses under the sunny Aegean Sea Climatic conditions. © 1983.
