AI Technical Summary

Technical Problem

The complex pipelines and large pressure losses in external supply structures of commercial air conditioning units reduce the efficiency of compressors.

Method used

A multi-stage compressor with a flash tank integrated within the compressor, connecting the flash tank's refrigerant inlet with the high-pressure stage suction and liquid outlet with the evaporator, reducing pressure losses and enhancing refrigerating capacity.

Benefits of technology

The integration of the flash tank improves compressor efficiency by enlarging the enthalpy difference of refrigerant entering the evaporator, increasing refrigerating capacity and reducing the compressor's footprint.
