Investigation of heat exchange processes in vertically arranged heat exchangersToday, in many countries, electricity is produced in a variety of ways, depending on current trends. The use of heat pump technology in heat energy development is one of the most efficient energetic methods. In order to save energy, it makes possible to use heat of subsurface water, reservoirs, natural water flows, etc. The environmental effectiveness of this technology is that it helps to prevent greenhouse gas emissions caused by combustion. Therefore, it is the use of gas and liquid fuel in the system that is one of the main and actual problems of operating heat pumps, but not replacement of old boilers. It will not only reduce fuel consumption, but also reduce carbon dioxide emissions to the atmosphere. In the laboratory of «Unconventional Energy Sources», experiments were conducted on an assembled test bench to study heat exchange processes taking place in a ground heat exchanger. The temperature distribution data in the vicinity of a U-shaped ground heat exchanger was experimentally specified. They showed temperature changes around the pipe in the ground. Using the obtained data, dependency graphs were constructed. The temperature change depending on different moisture content of the sand was determined. The temperature variation dependency graph with temperature difference of different moisture content was plotted.
