Abstract
Energy-saving technologies of port facilities and shipyards on the basis of geothermal heat pumps are a very promising direction. The features of offshore facilities are their presence in the zone of influence of seepage flow of ground water, significantly complicating the introduction of energysaving geothermal systems. The results of mathematical modeling of temperature field of soil mass, generated during the operation of the vertical ground heat exchanger of geothermal heat pump over 5 years are presented. The developed method is based on the equation of unsteady heat conduction and setting of boundary conditions for the different operating modes of the heat pump. The results of the temperature field changes were suggested in three modes of operation of geothermal plants: without changing the direction of heat flow, with a change in the direction of heat flow (regeneration) and in the condition of complicated influence of filtration flow of groundwater. The studies were conducted in order to build computational models that are adequate to real physical processes. The method of similarity theory is used to generalize the results.
