BOREHOLE HEAT SUPPLY SYSTEM WITH UNDERGROUND HEAT-HYDRO-ACCUMULATION Russian patent published in 2009 - IPC F24D15/04 F24H4/02 

FIELD: heating.

SUBSTANCE: borehole heat supply system with underground heat-hydro-accumulation contains water source, connected to feeding tank, communicating to it water conduit, bottom end of which is connected to flow area, installed in water conduit hydraulic turbine, interlocked to located lowerc vortical heat-generator of disk type, casing of which are implemented with ability of fixation and perception by it of reaction moment by reference element under working level of water, pressure of which is enough for manufacture of heat energy. Water conduit is well, water source is superficial reservoir, in area of which it is drilled well or drilled and communicated to it underground water-bearing zone or zones or superficial reservoir with underground zone or zones of communication of feeding tank to water conduit, outfitted by variable water flow control device, for instance regulator-shutter, well space up to placement location of vortical heat-generator is drilled by upright method. Borehole system also contains heat-water consumer, with heat network, allowing input and output pipelines. Hydraulic turbine and vortical heat-generator of disk type are unitised and amount borehole hydro-heat-aggregate, casing of which are rigidly connected, hydraulic turbine is located higher vortical heat-generator of disk type, reference element is pipe string pulled down into well, top end of which is fixed on well head, hydro-heat-aggregate is connected to bottom end of pipe string. Flow area is absorbing space of natural or artificial origin, for instance formed by means of cracking by hydro-rupture collector. It additionally includes production well, which is drilled, for instance formed by means of cracking by hydro-rupture collector, communicated to it, and in conditions when downstream absorbing space is not intersect to vertical well route, well space lower the placement location of hydro-heat-aggregate is drilled as directed up to intersection to flow area. Input pipeline of heat-water consumer is connected to production well, and its output pipeline - to well.

EFFECT: expansion of use environment of downhole system of heat supply, extension of its functional capabilities - giving of ability to accumulate and keep heat energy output, and implementation of closed cycle of heat supply with cost minimisation for creation of heat networks of heat-consumer and heat losses in it.
