The influence of the size of air cells on the resistance to a heat transfer of the building envelope

The article presents the idea advanced in the Patent N. 168609, A Multi-Layer Wall which deals with the interior cladding that increases the resistance to heat transfer. The influence of the size of a closed air cell on the resistance to heat transfer has been studied in it. To that end, the method of determining the heat resistance of heterogeneous constructions has been adapted to the object of study. A variable part representing the mutual dependence of air cells and bars is the bar in the intersection of the mutually perpendicular rows of bars. Applying our technique, data have been obtained for the bars with the length and height of 25, 30, 40 … 70 mm and for the bars of the variable thickness of 30, 40 … 70 mm. The mathematical experiment has been carried out to compare the options of the outside wall. The article presents the researches and calculations graphically and numerically which confirm the usefulness of the patented invention.
