Abstract

Provided are a centrifugal compressor gas-supplementing structure and a compressor using the foregoing gas-supplementing structure. The centrifugal compressor gas-supplementing structure includes a annular gas-supplementing passage (6) for introducing supplemented gas into a gas passage (5) of a compressor, and an airflow-guiding assembly is provided in the annular gas-supplementing passage (6). The gas-guiding assembly is used for adjusting a direction of the supplemented gas flowing into the gas passage (5), so that an angle between a direction of the supplemented gas flowing into the gas passage (5) and a direction of an airflow in the gas passage (5) falls within a preset range, and a turbulence loss generated when the two passages of gas merge is avoided to the greatest extent, thereby improving cycle efficiency.
