Thornton, Colorado Patent of the Year – 2024/2025
Air Squared Inc. has been awarded the 2024/2025 Patent of the Year for its innovative dual-drive co-rotating spinning scroll compressor or expander. Their invention, detailed in U.S. Patent No. 11933299, titled ‘Dual drive co-rotating spinning scroll compressor or expander’, utilizes a novel configuration where two scrolls rotate on separate axes within a shared housing, enhancing efficiency and performance.
This technology introduces a dual-drive mechanism that allows both scrolls to spin concurrently, reducing mechanical stress and improving operational balance. The design incorporates permanent magnets within the scroll extensions, functioning as rotors for integrated motors, which streamlines the device and minimizes energy loss. An Oldham ring maintains precise alignment between the scrolls, ensuring consistent compression or expansion cycles.
The real-world impact of this advancement is significant. By optimizing the scroll compressor and expander design, the technology offers improved energy efficiency and reliability in various applications, including HVAC systems, refrigeration, and industrial processes. The oil-free operation aligns with environmental standards, reducing maintenance needs and potential contamination risks.
Air Squared’s commitment to innovation in scroll technology continues to set industry benchmarks. Their latest patent exemplifies how reimagining traditional components can lead to substantial improvements in performance and sustainability.
