This aim is realized, as three typical for the practice cases are examined. They are connected to the heat transfer through a window of a residential room, from a tube with warm water to the environment and in a steel recuperator for air preheating by the internal energy of the outgoing fue gas from an industrial furnace. The results from the quantitative analysis of the influence of the radiative constituent in the total low-temperature heat transfer are commend and on the basis of them are formulated concrete ascertainments, to what kind of errors would lead the neglecting of the discussed mechanismenArticle
