SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18588301 titled 'SCROLL COMPRESSOR
The abstract describes a scroll compressor with features such as an orbiting scroll, a non-orbiting scroll, a back pressure chamber assembly, a back pressure passage, and a flow resistance portion. The back pressure passage connects the compression chamber and the back pressure chamber, while the flow resistance portion reduces refrigerant flow through the passage to improve sealing stability and compression performance.
- Back pressure passage reduces refrigerant flow
- Flow resistance portion decreases cross-sectional area
- Enhances sealing stability between scrolls
- Lowers pressure pulsation in back pressure chamber
- Improves compression performance
Potential Applications: - Air conditioning systems - Refrigeration units - Heat pumps
Problems Solved: - Pressure pulsation in back pressure chamber - Sealing stability between scrolls - Refrigerant flow control
Benefits: - Enhanced compression performance - Improved sealing stability - Reduced pressure pulsation
Commercial Applications: Title: Enhanced Scroll Compressor Technology for HVAC Systems This technology can be used in various commercial HVAC systems, refrigeration units, and heat pumps to improve efficiency and performance.
Questions about Scroll Compressor Technology: 1. How does the flow resistance portion improve sealing stability between the scrolls? 2. What are the specific benefits of reducing pressure pulsation in the back pressure chamber?
Original Abstract Submitted
A scroll compressor is provided that may include an orbiting scroll, a non-orbiting scroll, a back pressure chamber assembly, a back pressure passage, and a flow resistance portion. The back pressure passage may provide communication between a compression chamber and a back pressure chamber, and the flow resistance portion may be disposed at a middle portion of the back pressure passage to reduce an amount of refrigerant flowing through the back pressure passage. This may reduce a substantial cross-sectional area of the back pressure passage while improving machining of the back pressure passage, thereby decreasing an amount of refrigerant flowing between the compression chamber and the back pressure chamber. Accordingly, pressure pulsation in the back pressure chamber may be lowered and sealing stability between the orbiting scroll and the non-orbiting scroll may be enhanced, thereby improving compression performance.
