Centrifugal air compressor efficiency.

Centrifugal compressor centrifugal compressors. Ingersoll rand provides products services and solutions that enhance our customers energy efficiency productivity and operations. Available in up to four stages centrifugal air compressors are on average 5 more efficient than older compressor. Compressor efficiency increases with impeller size both due to reynolds number effect and reduced relative surface roughness.

In this example case the operating range for the compressor is approximately 1 42 1 62 kg s with the pressure ratio of 1 47. For the relatively small high speed centrifugal compressors in the 200 to 700 kw th capacity range peak efficiency increases about 2 for each jump in frame size. The energy calculations based on the compressor improvement scenarios focus on a centrifugal compressor delivering air in the primary process of the illustrated system in fig.
