Investigation of thin film energy-saving coatings

Abstract

Abstract. The report presents the results of an experimental study of the thermophysical properties and energy efficiency of thin-film energy-saving coatings consisting of hollow microspheres and a binder material from styrene-acrylic dispersion. The value of the thermal conductivity coefficient of the energy-saving paint is estimated depending on its composition and temperature, and the thermal diffusivity coefficient is determined. Experimental results of energy efficiency of using thin-film coatings for insulation of facades of buildings and as thermal insulation for pipelines with a hot coolant are presented.

Features of mathematical modelling of the microclimate of the non-productive building

“…The geometric and grid models of the experimental room of the university's educational audience in the ANSYS Fluent SCC and the features of the computing process of microclimate parameters are described in detail in the paper [8]. Figure 1 shows the results of mathematical modeling and experimental measurement of air temperature at four points in the experimental room: in the center of the room (point 1 on the figure 1), at a distance of 0.5 m from the left wall (point 2 on the figure 1) and at a distance of 0.5 m from the front wall (point 3 on the figure 1).…”
