Abstract
New energy-saving enclosing structures with air gaps are proposed; when calculating the temperature fields in the enclosing structures, the method of finite element analysis in the ANSYS environment was used. As a result of the study, the temperature fields of various enclosing structure solutions in various design options were analyzed. An analysis was made of the thermal resistance values of traditional and developed enclosing structures. The thermal resistance of the cladding with the use of two ventilated layers relative to the traditional enclosure, as well as the use of a heat-reflecting screen, depending on the environmental indicator, significantly increased the thermal resistance from 4.7% to 24.5% of the structure as a whole, which indicated the effectiveness of the constructive solution of the enclosure with two air gaps compared to the traditional constructive scheme of the enclosure. It was also found that the use of a heat-reflecting screen on the inside or on both sides has little effect on thermal resistance. At the same time, claddings were analyzed using horizontal channels. Where there was no efficiency, however, when taking into account the heat-reflecting screen in the horizontal channels, the efficiency of use increased from 1% to 8.4%, depending on the environment.
