Summary

Centrifugal compressors are used for gas compression in several engineering applications. In refrigeration, a number of a dvantages, such as compact size, thermodynamic efficiency in different operati on velocities, low noise and vibration levels, justifies their application in detriment of positive displacement compressors. However, as far as low refrigeration capacity is concerned, the app lication of centrifuga l compressors requires extremely high speed levels. [...]
