Features of Calculation of Temperature Fields When Designing Enclosing Structures

The thermal imaging survey of the structure, according to which was established the decrease in the surface temperature in the local sections of the structure, was analyzed. On the basis of this survey, a numerical simulation of this structure was carried out with boundary conditions corresponding to the climatic conditions of Moscow as well as according to the design temperatures adopted during thermal mapping. Results of the comparative study of the calculation of temperature fields and the thermal imaging of the structural component studied are presented. For taking into account the contiguity of various materials of the construction to each other, so the thermal conductivity of these materials in a multilayer structure, as well as the features of the installation of the construction, certain «assumptions» were made to the heat engineering calculation. The nature of the temperature distribution in the thickness and on the surface of the construction was studied in accordance with the established assumptions.
