SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240318654 titled 'SCROLL COMPRESSOR
Simplified Explanation:
The scroll compressor described in the patent application includes a back pressure passage that allows communication between the compression chamber and the back pressure chamber. This design helps guide compressed refrigerant from the compression chamber to the back pressure chamber, adjusting pressure levels as needed.
- The back pressure passage connects the compression chamber to the back pressure chamber.
- The passage is located at the front end surface of a non-orbiting wrap facing an orbiting end plate.
- When the orbiting scroll tilts, the non-orbiting wrap moves away from the orbiting end plate, opening a back pressure hole.
- This allows for quick adjustment of pressure in the back pressure chamber based on the compression chamber's pressure.
- The system adapts to different operating modes and conditions, improving sealing power and reducing excessive contact.
Potential Applications:
This technology can be applied in various refrigeration and air conditioning systems where precise pressure control is essential. It can also be used in industrial applications where efficient compression of gases is required.
Problems Solved:
This innovation addresses the need for quick and adaptive pressure adjustments in scroll compressors to optimize performance and prevent damage due to excessive pressure differentials.
Benefits:
- Improved sealing power - Enhanced efficiency in pressure control - Prevention of excessive contact and wear - Adaptability to different operating conditions
Commercial Applications:
The technology can be utilized in HVAC systems, refrigeration units, and industrial compressors to enhance performance, reduce maintenance costs, and increase overall system reliability.
Questions about Scroll Compressor Technology:
1. How does the back pressure passage in the scroll compressor contribute to pressure control? 2. What are the potential benefits of using this innovative scroll compressor design in industrial applications?
Original Abstract Submitted
a scroll compressor may include a back pressure passage that provides communication between a compression chamber and a back pressure chamber to guide refrigerant compressed in the compression chamber partially to the back pressure chamber. the back pressure passage may communicate with the compression chamber through a front end surface of a non-orbiting wrap axially facing an orbiting end plate. accordingly, when an orbiting scroll tilts, the non-orbiting wrap may be spaced apart from the orbiting end plate to open a scroll back pressure hole, such that the compression chamber and the back pressure chamber communicate with each other to quickly vary pressure in the back pressure chamber to be adaptive to the pressure of the compression chamber. this may result in appropriately adjusting back pressure in the back pressure chamber according to an operating mode and/or operating conditions, thereby increasing a sealing power and suppressing or preventing excessive contact.
