Numerical simulation device for the transport of geothermal heat with forced circulation of media

This article deals with the acquiring of low‐potential energy with vertical ground heat exchangers and gravity U‐tube. These two systems are a part of the device (simulator) for low‐potential heat transport through the phase changes in the vaporization and the condensation part of the tube at temperatures below 0 °C. So, the device thus allows a development of research activities during the verification of the technological production of a heat pipe that is suitable for the utilization of terrestrial heat at low temperature in a laboratory environment. The individual components of the device allow a research of thermo‐kinetic heat transport parameters and realistic modeling of a heat flow from the rock into the heat transfer fluid.
