Centrifugal Air Compressor Efficiency

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.

Centrifugal air compressor efficiency.

Ingersoll rand provides products services and solutions that enhance our customers energy efficiency productivity and operations. 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. Compressor efficiency increases with impeller size both due to reynolds number effect and reduced relative surface roughness. We also enhance productivity through solutions created by club car the global leader in golf and utility vehicles.

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. Fs elliott air compressors take maintenance friendly operation a step further by offering a horizontally split gear case allowing full access to the gearbox in the field and avoiding costly downtime. Available in up to four stages centrifugal air compressors are on average 5 more efficient than older compressor.
