SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18595658 titled 'SCROLL COMPRESSOR
The abstract describes a scroll compressor with a back pressure passage that allows communication between the compression chamber and the back pressure chamber, enabling quick adjustment of pressure in the back pressure chamber based on the pressure in the compression chamber.
- The back pressure passage guides compressed refrigerant from the compression chamber to the back pressure chamber.
- Communication between the chambers is facilitated through a front end surface of a non-orbiting wrap facing an orbiting end plate.
- When the orbiting scroll tilts, the non-orbiting wrap opens a scroll back pressure hole to adjust pressure in the back pressure chamber.
- This adjustment helps increase sealing power and prevent excessive contact in the compressor.
- The innovation allows for adaptive pressure control in the back pressure chamber based on operating conditions.
Potential Applications: - HVAC systems - Refrigeration units - Air compressors
Problems Solved: - Quick adjustment of back pressure in response to changes in compression chamber pressure - Increased sealing power and prevention of excessive contact
Benefits: - Improved efficiency in scroll compressors - Enhanced performance in various applications - Reduced wear and tear on compressor components
Commercial Applications: Title: Adaptive Pressure Control System for Scroll Compressors This technology can be utilized in various commercial applications such as HVAC systems, refrigeration units, and air compressors, improving efficiency and performance while reducing maintenance costs.
Questions about the technology: 1. How does the back pressure passage in the scroll compressor facilitate communication between the compression and back pressure chambers? 2. What are the benefits of adaptive pressure control in scroll compressors for different operating conditions?
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.
