摘要： A helical pile including a heat exchanger is described. The pile is formed from a lead section and one or more extension sections. The interior of the lead and extension sections are hollow and form a heat exchanger cavity. At the lower end of the lead section is a helical blade. Rotation of the lead section causes the helical blade to screw into the ground, thus pulling the lead section downward. Extension sections are added to the lead section and the pile is rotated until it is installed to a desired depth. The pile includes an inflow tube extending a predetermined distance into the heat exchanger cavity and an outflow port connected with the heat exchanger cavity. In operation, a heat carrying fluid is pumped into the inflow tube from a heat source or sink, for example, a heat pump for a building heating and cooling system. The fluid exits the tube at a point near the bottom of the heat exchanger cavity. The fluid flows upward through the heat exchange cavity and exchanges heat with the surrounding soil. The fluid flows out through the outflow port and back to the heat source or sink.

摘要： A geothermal development system includes a ground lifting system, a large-diameter shaft, an underground high temperature and high pressure heat transfer pool, a heat transfer diversion channel, a hot mine blasting fracture reservoir formed by an inlet blasting tunnel and a main tunnel, and a removable sealing device. The injection pipe and the collection pipe are set along the large diameter silo wall in the geothermal development system. The injection pipe is connected to the collection pipe through the heat transfer diversion channel in the dry hot rock. The circulation main roadway is arranged around the underground high temperature and high pressure heat transfer pool. Multiple blasting roadways are set along the main roadway level to form hot mine blasting fracture reservoir with loose blasting by caving method. A movable sealing device is arranged above the blasting layer of the large-diameter shaft.

摘要： An induced groundwater flow closed loop geothermal system provides safety associated with closed loop geothermal systems (e.g., no mixing of surface water, closed system fluid, and groundwater) and efficiency associated with open loop geothermal systems (e.g., increased heat transfer provided by groundwater flow). A heat exchanger connected to an external system is located in a hole in a geological formation. The hole has a depth below where groundwater is located. A fluid from the external system is routed through the heat exchanger. A pump is utilized to induce groundwater flow from the geological formation, across the heat exchanger and back to the geological formation to enable thermal transfer between the fluid and the groundwater and the groundwater and the geological formation. A casing may be located in the hole to provide structural support and grouting materials may be used to fill space around the casing enabling a groundwater flow path.

摘要： Systems and methods for generating electrical power using a solar power system that comprises a pressurized closed loop pipe containing a transfer liquid extending between a solar collector and a heat exchanger. The transfer liquid is heated by the solar collector and gives up its thermal energy at the heat exchange to produce steam. The system also includes a source of geothermal energy and a source of natural gas. The geothermal energy in the form of heat separates the natural gas from the ground water in a separation tank. At the resulting heated ground water from the separation tank is connected to the heat exchanger to supplement thermal energy from the solar collector.

摘要： A unique method and ternary cycle process that captures heat from low temperature sources currently considered not commercially usable to produce electricity and desalinate water. In one cycle a novel flash tower operating at vacuum pressure causes a fraction of low temperature water to flash into steam. The steam passes to an indirect heat exchanger with a circulating refrigerating agent such as CO2, which condenses the steam on its outside surfaces to produce desalinated water product. The steam heat of condensation vaporizes the refrigerating agent, which is part of a binary refrigerate cycle that uniquely conditions it for turbine expansion to produce electricity in a connected electric generator.

摘要： A heat exchanger includes at least one flat tube configured to allow a refrigerant mixture inclusive of HFO1123, R32, and HFO1234yf to flow therethrough as a heat medium. The flat tube includes a plurality of flow paths for the heat medium. Each of the plurality of flow paths has a round rectangular shape in cross section, the round rectangular shape being defined by a pair of longitudinal line segments opposed to each other, a pair of lateral line segments opposed to each other, and a set of four rounded corners, each of the rounded corners being a segment of a circumference of a circle. The pair of longitudinal line segments are intersects with the pair of lateral line segments at the rounded corners. The round rectangular shape is configured to satisfy 0.005≦r/d≦0.8 where r is a radius of the circle, and d is a distance between the pair of longitudinal line segments opposed to each other.
