Jochim, Stanislav, 1972- Determining the heat transfer coefficient of insulated log-cabin walls based on one-dimensional heat conduction / Stanislav Jochim. -- Obr., tab. -- Lit. - An accurate calculation of heat transfer coefficient (U-value) for the insulated log-cabin walls in the practice is carried out using a difficult method of two-dimensional heat conduction, or using experimental measurement. This is due to the various thicknes of the wall layers – log-cabin and thermal insulation. The calculations are demanding form the professional point of view, as well as from the time aspect. Furthermore, it requires the use of specific programmes. Experimantal measurements are demanding due to the same reasons. The aim of the paper is to propose a simplified and accurate determinantion of the heat transfer coefficient of insulated log-cabin walls using the modification of the method according to the STN EN ISO 6946 following the one-dimenaional heat conduction. The basis for the method modification is to determine the exact substitution method for the substitution of the profile of insulated log-cabin walls to a constant thickness. The paper determines and analyses two substitution methods of wall layers – dimensional and areal. When using the areal substitution method the modified methodology according to the STN EN ISO 6946 is suitable for a simplified and accurate calculation of the U-value of insulated log-cabin wall or other similar wall constructions.
