FIELD: heat power engineering.
SUBSTANCE: invention relates to heat engineering and can be used in heat supply systems of residential, administrative and production facilities of capital construction. Geothermal device for waterproof soils consists of drainage reinforced concrete chamber, in the lower part of which there is a geothermal U-shaped probe, which provides circulation of heat carrier, mounted in geothermal well in casing filled with filler with high draining capacity in form of coarse sand, which is moistened with ground and storm water from system of natural moistening of filler of geothermal probe through reinforced concrete chamber.
EFFECT: technical result consists in increase of heat capacity of ground heat exchanger using arranged gravity-flow collection of ground, sedimentary water with subsequent moistening of filler of geothermal well, and also significantly expands the field of application in areas with availability of water-resistant soils, having low natural moisture content.
