AI Technical Summary
Technical Problem
In compressor devices with multiple compressors operating at different suction and discharge pressures, the high-stage compressor experiences a larger discharge of lubricant, leading to a potential shortage of lubricant.
Method used
A compressor device with a two-stage compression system using carbon dioxide as refrigerant, incorporating oil discharge and return mechanisms to balance lubricant distribution across compressors, including oil separators and coolers to manage lubricant levels.
Benefits of technology
The solution effectively reduces lubricant discharge from the high-stage compressor, maintaining adequate lubrication levels and enhancing the efficiency and reliability of the refrigeration apparatus.
