Centrifugal Air Compressor Efficiency

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.

Centrifugal air compressor efficiency. 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. Ingersoll rand provides products services and solutions that enhance our customers energy efficiency productivity and operations. Compressor efficiency increases with impeller size both due to reynolds number effect and reduced relative surface roughness. A centrifugal compressor is a radial flow rotodynamic fluid machine that uses mostly air as the working fluid and utilizes the mechanical energy imparted to the machine from outside to increase the total internal energy of the fluid mainly in the form of increased static pressure head.

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 compressor centrifugal compressors. 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.
