Mathematical Simulation of the Thermal Technical Characteristics of External Enclosing Structures with Air Spaces

A screened enclosing structure devoid of heat insulating materials is suggested. To ensure the needed thermal resistance of the external enclosing structure, screens (cement-containing slabs) and closed air spaces between them are employed. With the use of the software suite ANSYS, modeling of the processes of heat transfer in a screened enclosing structure consisting of the main (supporting) part and of screens with air spaces enclosed between them is made. The characteristic features of the process of heat transfer inside the external enclosing structure have been elucidated.
