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 A device 100 according to the present disclosure arranged as a closed loop heat pump, such as a refrigeration unit, is illustrated.

[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 . First mandrel 120 (similar to mandrel 20 ) defines a second axis of rotation 132 (similar to axis of rotation 32 ) through which first shaft portion 118 extends. The second axis of rotation 132 is substantially perpendicular to the first axis of rotation 130 . A first piston member 122a (similar to the first piston member 22 ) is disposed on the first shaft portion 118 , the first piston member 122a extending from the first mandrel 120 towards the distal end of the first shaft portion 118 . The first rotor 119 (similar ...

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

[0178] Figure 16 Another example of a closed loop heat pump is illustrated, such as a refrigeration unit. The example includes the same Figure 15 A number of features are identical or equivalent to the examples of the present invention and are therefore referred to by the same reference numerals.

[0179] Thus, device 200 includes a Figure 15 Examples of the first fluid flow section 111 can operate as a compressor or a 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 Figure 15 An example of the 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 flow inlet / outlet.

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

[0228] Figure 19 An example of a closed-loop heat engine (eg, energy harvesting generator) arrangement 400 according to the present disclosure is illustrated that includes a combination with Figure 15 Examples of the same and potentially many features that are physically the same or equivalent, and these features are therefore 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 is capable of being driven by the first shaft 118 . The power output device 408 is configured 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 (rather than the heat sink of Example 1), and the second heat exchanger 306a is configured as a heat sink (rather than the heat source of Example 1...

Abstract

A rotationally articulated thermodynamic device (100) having a first fluid flow section (111) and a second fluid flow section (115). The first fluid flow section (111) is configured for passing fluid between the first port (114a) and the second port (114b) via the first chamber (134a). The second fluid flow section (115) is configured for passing fluid between the third port (116a) and the fourth port (116b) via the second chamber (134, 234b). The second port (114b) is in fluid communication with the third port (116a) via the 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 usually 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 are often of different types and rotate independently of each other to allow the pumps and turbines to run at different speeds. [0005] Additionally, conventional pump and turbine equipment requires consistent operating speeds to maximi...
