摘要： Pressure changing devices and methods of making and using the same are disclosed. One pressure changing device includes an elliptic cylinder and a piston that has an external surface with a trochoid cross-section. Another pressure changing device includes a piston and a rotating cylinder that has an internal surface with a trochoid cross-section. Another pressure changing device includes two fixed axes, one for rotation of one component and another for orbiting or oscillation of the other component. The devices and methods include stacked pressure changing devices with one or more common shafts. The pressure changing device may be easier and less expensive to manufacture and repair than prior pressure changing devices of the same or similar functionality, and can provide efficient gap sealing in a high-pressure expansion part of a compression or expansion cycle.

摘要： Systems and methods for storing and retrieving thermo-mechanical energy are disclosed. The systems and methods generally include a thermodynamic loop or cycle (e.g., a reversible transcritical, trilateral, or Rankine/vapor compression cycle) that works as a heat pump in a charging mode and as a heat engine in a discharging mode. The thermodynamic loop or cycle includes a gas pressure changing device, a liquid pressure changing device, and a working fluid. The system further includes one or more heat storage devices with solid heat storage material(s). Heat is transferred between the working fluid and the solid heat storage material(s) in the high and low pressure sides of the thermodynamic cycle, respectively.

摘要： Systems and methods for storing and retrieving thermo-mechanical energy are disclosed. The systems and methods include a thermodynamic cycle (e.g., a reversible transcritical, trilateral, Brayton or Rankine/vapor compression cycle) that includes a plurality of loops and works as a heat pump in charging mode and as a heat engine in discharging mode. Each loop in the thermodynamic cycle includes pressure increasing and decreasing devices, high and low pressure heat exchanging devices, and the same or different working fluid. The system further includes one or more heat storage chains with hot and cold storage reservoirs and a heat storage fluid. At least one of the high and low pressure heat exchanging devices is a gradient heat exchanging device that exchanges heat with the heat storage chain. Also, at least one other high or low pressure heat exchanging device exchanges heat with a separate heat storage device or a heat source or sink.

摘要： The present disclosure concerns liquid ring systems, including (i) a fixed or rotating casing adapted to contain a liquid, (ii) a rotor located within the casing and having at least one impeller, (iii) a liquid ring formed by rotation of the rotor or the casing, and (iv) a plurality of gas cells formed between the inner surface of the liquid ring and vanes of the impeller. For example, at least one compressing gas cell is in fluid connection with at least one expanding gas cell integrated with the rotor. A liquid valve may include a small gas cell with a reciprocating liquid surface and at least two fluid connections having a free pathway between the connections during an angle of rotation of the rotor and a closed pathway between the connections during 360° minus the angle of rotation.

摘要： A solar energy collector and/or concentrator, a thermal energy storage and retrieval system including the same, and methods of storing and recovering thermal energy are disclosed. The solar energy collector and/or concentrator may include an array of lenses configured to concentrate solar energy, a plurality of conduits through which a heat storage or heat transport fluid flows, and one or more heat transfer elements on each of the conduits, configured to receive the concentrated solar energy from the lenses and transfer the concentrated solar energy to the heat storage/transport fluid. The conduits are configured to move in at least first and second angular dimensions. The thermal energy storage and retrieval system may include the solar energy collector and/or concentrator, a thermodynamic cycle, and a heat storage and retrieval subsystem. Heat is transferred from the heat storage/transport fluid to the heat storage and retrieval subsystem and/or the thermodynamic cycle.
