Thermal Efficiency of Trombe Wall in the South Facade of a Frame Building

Abstract

The article presents the possibility of using a mass collector-storage wall (CSW), integrated into the structure of a building with a light skeleton structure. The considered system is a proposal for an energy-saving solution that can be used in buildings with various utility purposes. The article presents the results of experimental tests of a collector-storage wall mounted in the space of the skeleton structure of the southern facade of a building for the period of one year, as well as the results of numerical simulation. In the summer, the influence of the use of heat-insulating roller shutters on limiting overheating of the chamber interior was investigated. The effect of using the roller shutters is a reduction in the average value of the heat flux by about 77%. In the winter, the energy efficiency of the wall was tested. The obtained effect is energy consumption during the heating season at a level comparable to a wall with a traditional structure with a coefficient of U = 0.30 W/(m2K). The results of the numerical tests showed high agreement with the direct results, which provides a basis for the use of such simulations in further research on the search for the optimal structure of a collector-storage wall.

The Influence of Glazing on the Functioning of a Trombe Wall Containing a Phase Change Material

“…The aim of the research in the article [9] was to analyze the heat flow through the Trombe wall with shutters inclined at different angles. At the same time, the Trombe wall, equipped with an external shutter, was placed in a skeleton steel structure [10]. Tests of its energy efficiency were carried out in real climatic conditions.…”
