AbstractAbout AuthorsReferences
Heat transfer resistance is one of the main heat engineering characteristics which is taken into consideration when designers decide on the possibility of using the building envelope. The differential equation of heat conduction in stationary and non-stationary formulations with boundary conditions of the third kind is shown. The relationship between the heat flow through the fence and its heat transfer resistance is demonstrated. The current state of documentary standard in determining conventional, reduced and required heat transfer resistance is outlined. Scientific methods for determining the heat transfer resistance are demonstrated. T.A. Musorina and M.R. Petrichenko’s works which propose a calculation of the total thermal resistance by decomposing it into reactive and active components are reviewed. The work of O.D. Samarin describing a method for calculating the heat transfer resistance in soil using a quarter of an infinite array and dividing the soil into concentric circles is cited. Above mentioned O.D. Samarin’s method provides more opportunities compared to the classical method of calculating by zones. Furthermore, an overview of the experimental method for determining heat transfer resistance which consists in finding the average value of the heat flux density in each period with a steady temperature regime is presented. In conclusion, the necessity to improve both theoretical and experimental approaches to determining the heat transfer resistance is highlighted.
