MODELING OF THERMAL RESISTANCE OF THE DEVELOPED EXTERNAL ENCLOSING STRUCTURES WITH AN AIR LAYER

Abstract

The paper investigated the temperature fields in the enclosure under various boundary conditions, which were calculated in the ANSYS software package, where an iterative computational scheme was used to determine the thermal resistance of the interlayer or channel. It is found that of all the developed structures, the most effective is the construction with air layers with a heat-reflecting screen in the outer surface, which exceeds other structures in terms of thermal resistance: at a minimum outdoor temperature by 14.5%, at a maximum temperature by 14.2%, at an average temperature of the coldest five-day period by 16.7%, and at an average temperature of the temperature of the first month after the end of the heating period is 16%, and the thermal resistance of horizontal or vertical channels have almost the same values.
