ON THE DEPENDENCE OF THE TEMPERATURE INTENSITY OF HEAT TRANSFER IN MULTILAYER ENCLOSURE STRUCTURES IN THE CONDITIONS OF NORTHERN KAZAKHSTAN

Abstract

"The article presents studies on the intensity of the influence of temperature on the heat transfer inside the cement sandwich panel, taking into account the intensity of the influence of temperatures in the ranges of positive and negative values when determining the temperature distribution curve inside Protective construction for climatic conditions in Northern Kazakhstan. Three-layer cement sandwich wall panels, which contain basalt wool and foam polystyrene materials as insulation layer, are considered. The research was carried out using the computer program «Comsol Multiphysics» using the method of finite elements. The study of temperature change kinetics according to the thickness of the structures of two types of cement sandwich panels with the aim of revealing sharp temperature changes affecting the processes of material destruction. It has been shown that the temperature influence during the transmission of the heat flow under both decreasing and increasing temperature conditions flows under softer conditions during the passage of the heat flow through a structure comprising basalt wool as an insulating agent. Keywords: temperature, heat transfer, intensity of action, enclosing structure, insulation. "
