The thermotechnical characteristics of a thermally insulated door panel used in the manufacture of entrance door blocks for public buildings in low temperature conditions have been determined. An installation based on a ‘Terkon’ signal converter and a climate chamber was used for the study. Mathematical modeling was carried out using the ‘COMSOL’ software with boundary conditions of the 3rd kind – heat transfer at a difference in ambient and surface temperatures inside and outside the climate chamber.
