The goal of the work is on increase of heat-exchange equipment efficiency and development of effective geothermal heat supply system schemes. In the process of the research we used analytical and experimental methods. Adequacy of the results is ensured by well-grounded choice of experimental data processing methods, instrumentations, physical and mathematical models used. We developed and made an experimental model of a heat-exchanger comprising a weighed particles dynamic layer for the condition of operation with high mineralized thermal waters. Besides, we carried out theoretical and experimental analyses of heat-exchanging and hydraulic processes taking place within this heat-exchanger. We defined an influence of a material and size of the particles on heat-exchanging processes efficiency. We determined an advantage of the heat- exchanger comprising a weighed particles dynamic layer according to its thermotechnical characteristics and operational reliability over a lamellar and a pipe-housing heat-exchanger. We worked out the of defining the thermotechnical characteristics and power efficiency of the combined schemes of geothermal heat supply systems which may be used while designing and operating the systems.
