Restoration of the Soil Temperature Regime During Operation of a Heat Pump Unit Operating on the Principle «Ground Ground-Water»

The utilization of the heat pump installations operating on the principle of "ground-water" has a number of advantages over traditional sources of thermal energy. However, along with the advantages, there are disadvantages: the cooling of the array and, as a result, a decrease in the efficiency of the installation, the dependence of thermal power on the area of the heat exchanger. To solve this problem, a solution is proposed in the form of a heat pump unit operating in reverse mode in the warm season (heating of the soil mass), while the soil mass will be a heat accumulator. Research has been carried out on a laboratory installation, and the fundamental possibility of such approach has been shown.
