        <p>The study is devoted to a comprehensive thermodynamic analysis of work processes in pneumatic systems for feeding bulk materials in construction production. The relevance of the work is due to the need to increase the energy efficiency of transport systems with increasing demands on environmental safety and productivity of construction processes. The research methodology is based on the application of modern thermodynamic approaches to the analysis of gas-solid-phase flows, including experimental modeling of heat exchange and mass transfer processes in horizontal and vertical sections of pneumatic routes. The empirical base includes the results of field experiments on industrial installations of various capacities with registration of parameters of temperature fields, pressures and velocity characteristics of the two-phase flow. It has been found that optimization of thermodynamic parameters makes it possible to reduce specific energy consumption by 18- 24% while increasing system performance by 12-16%. The critical dependences between the temperature regime of the conveying agent and the efficiency of energy transfer to material particles, which determine the boundaries of stable operating modes, are revealed. The developed mathematical model of thermodynamic processes demonstrates a high correlation with experimental data, which confirms the possibility of its practical application for the design of highly efficient pneumatic systems. The research results provide a theoretical basis for engineering solutions in the field of automated building materials supply systems.</p>
