Segment Method for Calculation of Temperature Distribution along the Sectionof the Enclosing Structure of a Building
Methods for determining the number of cycles of the temperature transition via zero for different sections of enclosing structures of the building are presented.The basis of methods is the solution of the differential equation of heat conductivity of Fourier which determines the one-dimensional heat transfer under nonstationaryconditions at permanent coefficients with the help of the finite difference method. Developed methods make it possible to calculate the temperature at any section of the enclosing structure at any moment of time. At this, a real external temperature of the ambient air, not standard, participates in the calculation.To confirm the correctness of the developed methods, long-term testing on the external wall of the operated building has being conducted. The results of testsshowed a good convergence of calculated and experimental data. Methods for conducting tests and processing the experiment data are described in details.Comparison of the developed method with the methods of Muromov-Shklover and S.V. Aleksandrovsky shows its advantage.
