Electronic-physical model that determines thermal conductivity of walls made of various materials

The article analyzes data on creating an electronic-physical model designed to determine the thermal conductivity of walls from various loose or solid materials used in the agricultural sector and construction. At the end of 2022 and the beginning of 2023, during the abnormally cold winter days observed in the Republic of Uzbekistan, accidents were observed at many construction sites and in heating networks. In response to this, by the government's decision, practical work was carried out to cover buildings' outer part (facade) with special basalt material. The studies of one-dimensional heat transfer in a compound cylinder carried out in a stationary mode at a constant thermal conductivity of the material, are analyzed. In these studies, heat conduction equations were studied with the results of heat transfer simulations developed using the Ansys software. The electronic-physical model proposed in the article allows you to quickly and accurately measure the heat and thermal diffusivity of walls made of various materials. It will be possible to intelligently control the electronic-physical model using thermal sensors. The article contains detailed engineering calculations and illustrative materials. Internet data was analyzed, and specific conclusions were drawn. The prerequisites for the creation of an intelligent system for measuring the temperature and thermal conductivity of walls from various bulk materials are made in the work.
