THERMAL LOADS AT TRANSPARENT STRUCTURES INTEGRATED IN TROMBE WALLS

Abstract

This contribution presents thermal load stress analysis of insulating glass units (IGU) integrated in Trombe walls. It is based on modelling and numerical simulation of the heat transfer processes occuring in the construction. The boundary conditions are based on experimental data, obtained from an existing Trombe wall test module, situated at the Technical University of Sofia. The investigations are performed for different cases of IGU fixing in the Trombe wall. The temperature fields and the ensuing thermal stresses in the IGU at winter conditions, obtained from the simulations, are used to analyze the possibility of glass failure due to the internal pressure loads.
