Abstract
The invention discloses a centrifugal compressor and a water chilling unit having the same. The centrifugal compressor includes an impeller (), a diffuser (), a volute () and an exhaust diffuser pipe (), the diffuser () including a pressurization passage, air flowing through the impeller () entering an inlet of each pressurization passage, the volute () being configured to collect the air pressurized by the diffuser (), the exhaust diffuser pipe being communicated with the volute, and an extending direction of the exhaust diffuser pipe inclining downwards with respect to a horizontal plane. The extending direction of the exhaust diffuser pipe communicated with the volute inclines downwards with respect to the horizontal plane, so that noise and airflow losses of high-temperature and high-pressure air in the exhaust diffuser pipe expelled from the centrifugal compressor due to bending of the pipe can be reduced, and the noise can be effectively reduced.
