AI Technical Summary

Problems solved by technology

The true nature of most systems is that they tend to be optimized for a relatively narrow operating range, and operation outside of this range can result in very inefficient or unacceptable wear and tear on components
[0006] This means that for conventional heat pumps or conventional heat engines, large temperature differences are required to achieve sufficiently high operating speeds, which means that such equipment cannot be operated in environments where only low temperature differences are available
This limits the effectiveness of such conventional devices

example 1

[0129] Example 1 - Single Unit, Closed Loop, Heat Pump

[0130] Figure 15 An apparatus 100 according to the present disclosure is illustrated arranged as a closed loop heat pump, eg, a refrigeration unit.

[0131] as reference Figure 1 to Figure 14 As depicted, device 100 includes a first shaft portion 118 (similar to shaft 18 ) that defines a first axis of rotation 130 (similar to axis of rotation 30 ) and is rotatable about first axis of rotation 130 . The first mandrel 120 (similar to the mandrel 20 ) defines a second axis of rotation 132 (similar to the axis of rotation 32 ) through which the first shaft portion 118 extends. The second axis of rotation 132 is substantially perpendicular to the first axis of rotation 130 . Disposed on the first shaft portion 118 is a first piston member 122a (similar to the first piston member 22 ) extending from the first mandrel 120 toward the distal end of the first shaft portion 118 . The first rotor 119 (similar to Figure 1 to ...

[0177] Example 2 - Dual Unit, Closed Loop, Heat Pump

[0178] Figure 16 Another example of a closed loop heat pump, such as a refrigeration unit, is illustrated. This example includes Figure 15 Examples of the same or equivalent many features, and therefore these features are referred to with the same reference numerals.

[0179] Thus, the device 200 includes something like Figure 15 An example of a first fluid flow section 111 that can operate as a compressor or displacement pump. The first fluid flow section 111 has a first port 114a and a second port 114b operable as a flow inlet / outlet.

[0180] Apparatus 200 also includes something similar to Figure 15 An example of a second fluid flow section 115 that can operate as a metering section or an expansion section. The second fluid flow section 115 has a third port 116a and a fourth port 116b operable as a flow inlet / outlet.

[0181] The device 200 includes a first shaft portion 118 that defines a first axis of rota...

[0227] Example 3 - Single Unit, Closed Loop, Heat Engine

[0228] Figure 19 An example of a closed-loop heat engine (eg, energy harvesting generator) apparatus 400 according to the present disclosure is illustrated, including Figure 15 Examples of the same and potentially physically the same or equivalent many features, and therefore these features are referred to with the same reference numerals.

[0229] Figure 19 example with Figure 15 The example differs in that a power off take 408 is coupled to the first shaft 118 instead of the motor 308 and the power off take 408 can be driven by the first shaft 118 . The power take-off 408 is provided as a coupling of a gearbox for driving another device, such as a generator.

[0230] Likewise, the first heat exchanger 302a is configured as a heat source (instead of the heat sink of Example 1), and the second heat exchanger 306a is configured as a heat sink (instead of the heat source of Example 1). besides, Figure 15 , F...

Abstract

A roticulating thermodynamic apparatus (100) having a first fluid flow section (111) and a second fluid flow section (115). The first fluid flow section (111) is configured for the passage of fluid between a first port (114a) and second port (114b) via a first chamber (134a). The second fluid flow section (115) is configured for the passage of fluid between a third port (116a) and a fourth port (116b) via a second chamber (134, 234b). The second port (114b) is in fluid communication with the third port (1 16a) via a first heat exchanger (302a).

Description

technical field [0001] The present disclosure relates to roticulating thermodynamic devices. [0002] In particular, the present disclosure relates to thermodynamic devices capable of operating as heat pumps and / or heat engines. Background technique [0003] Conventional heat pumps and heat engines that compress and expand a working fluid typically include a pump to pressurize the working fluid and a turbine to expand the fluid. This is because the most efficient conventional thermodynamic expanders tend to be rotary (eg, turbines) and are generally limited to a single-stage expansion ratio of 3:1. [0004] To optimize the performance of the system, the turbine is usually run at a higher speed than the pump. Therefore, the pumps and turbines tend to be of different types and rotate independently of each other to allow the pumps and turbines to operate at different speeds. [0005] Additionally, conventional pump and turbine equipment requires consistent operating speeds t...
