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 () for introducing supplemented gas into a gas passage () of a compressor, and an airflow-guiding assembly is provided in the annular gas-supplementing passage (). The gas-guiding assembly is used for adjusting a direction of the supplemented gas flowing into the gas passage (), so that an angle between a direction of the supplemented gas flowing into the gas passage () and a direction of an airflow in the gas passage () 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.
