Abstract

The article presents the results of research on a new technology for increasing the thermal insulation properties of fences based on sandwich panels for thermal insulation of buildings, storage facilities, cooling chambers, industrial and residential premises, as well as for the production, storage and transportation of agricultural products. The costs of cold and heat are reflected in the cost of agricultural products. The idea is to replace the air in the pores of mineral (basalt) wool with gas with low thermal conductivity. The article presents a theoretical analysis of the possible effectiveness of this substitution, and the developed research methodology. The analysis made it possible to predict a possible decrease in the heat transfer coefficient by about 21%. This is a very high indicator. It can be assumed that approximately this value can reduce the cost of electricity spent on maintaining rational temperatures. The scheme and description of the stand for experimental research, and the results of these studies are given. It was found that as a result of the conducted experiments, it was possible to obtain a decrease in the thermal conductivity of sandwich panels with argon by 8.8%, and with carbon dioxide by 10.2%.
