摘要： Systems and methods for improved geoheat harvesting enhancements are presented in which a wellbore contains a closed loop geoheat harvesting system that is thermally coupled to a hot and dry rock formation via thermal reach enhancement structures that extend from the wellbore into the formation and that are filled with a thermally conductive filler. Preferred configurations and/or operational parameters are determined by a model that calculates heat flow in a three-dimensional system considering time changes and the influence of the thermal reach enhanced intrinsic thermal conductivity of the rock.

摘要： Thermal energy is extracted from geological formations using a heat harvester. In some embodiments, the heat harvester is a once-through, closed loop, underground heat harvester created by directionally drilling through hot rock. The extracted thermal energy can be converted or transformed to other forms of energy.

摘要： A heat pump system and a method for implementing efficient evaporation by using a geothermal well are provided. The system includes a stepped underground evaporator, a compressor, a condenser, a liquid storage tank, and a throttle. The underground evaporator includes an inner pipe and an outer pipe. The inner pipe is designed into a multi-section structure. Each section includes a gas guiding pipeline, a baffle plate, and a seepage hole. Under the action of the structure, a liquid working medium flowing into the underground evaporator flows downwards along an inner wall of the outer pipe, and absorbs heat from an underground rock mass and gasifies into a gas working medium; and the gas working medium flows upwards to ground. Compared with the prior art, neither gas-liquid re-entrainment nor a liquid accumulation effect can occur in the underground evaporator designed according to the system and method.

摘要： A subterranean geothermal power generation system is disclosed herein, comprising a closed cavity, a temperature differential mechanical power generation device, an electric power generation device and a heat conduction module. The mechanical power generation device with a heat source end and a cold source end and the electric power generation device are integrated into the cavity. The heat source end is exposed from the cavity for contacting with a heat source in the well; the cold source end and the electric power generation device are located in the cavity. A heat conduction fluid is filled into the cavity, the heat conduction module extends from the cavity to the outside of the well. Accordingly, a temperature difference between the cold source end and the heat source end is created to enable the mechanical power generation device to mechanically drive the electric power generation device to generate electricity.

摘要： A concentric pipe geothermal heat exchanger well head is described. The well head may include a riser pipe having an outer pipe and an inner core pipe, wherein an inner heat exchanger pipe is coupled to the inner core pipe, a reducer coupled to an outer heat exchanger pipe on one side and coupled to the outer pipe on a second opposite side to conduct fluid between the outer heat exchanger pipe and the outer pipe, a flow pipe parallel to and biaxial with the riser pipe configured to be coupled to a geothermal heat pump, and an elbow coupled to the outer pipe to couple fluid between the outer pipe and the well head pipe.

摘要： The disclosure relates to a thermosiphon system operable to consistently maintain the permafrost and active frost layer in a frozen condition to adequately support buildings and other structures. During cooler seasons, the thermosiphon system uses a passive refrigeration cycle to efficiently maintain the frozen layers using the cold air. When the air temperature rises during the warmer months, the system transitions into an active refrigeration mode that uses a refrigeration system to minimize thawing or degradation of the permafrost and active frost layers.

摘要： The disclosure describes trench-confirmable geothermal reservoirs that can snugly abut trench walls (that may be of virgin, compacted earth) for facilitating heat exchange and flow liquid from one lower end to an opposing top end, and vice versa, depending on desired heat exchange. The direction can be reversed for summer and winter heat/cooling configurations. A series of the reservoirs may be used for appropriate heat transfer. The water volume of the reservoirs is relatively large and slow moving for good earth heat conduction.

摘要： Building heating and/or cooling methods are provided that can include: distributing fluid from within conduits within a concrete floor of a building to conduits within grounds surrounding and/or supporting the building; diverting at least some of the fluid exiting the conduits within the grounds surrounding and/or supporting the building to a dehumidifier operably associated with the interior of the building; and returning the at least some of the fluid from the dehumidifier to the conduits within the grounds surrounding and/or supporting the building.
