AI Technical Summary

Technical Problem

The existing dry-cleaning systems using carbon dioxide face inefficiencies in oil separation from refrigerants, leading to malfunction of components, decreased washing performance, and oil shortages due to pressure differences between oil separators.

Method used

A compression system with multiple oil separators connected in series, featuring capillary flow resistance bodies in connection and recovery pipes to manage oil flow and prevent shortages, ensuring effective oil separation and recovery.

Benefits of technology

This configuration enhances oil separation efficiency, reduces component malfunctions, improves washing performance by minimizing oil content in refrigerants, and prevents oil shortages in the compressor.
