Ingersoll rand provides products services and solutions that enhance our customers energy efficiency productivity and operations.
Centrifugal air compressor efficiency.
Compressor efficiency increases with impeller size both due to reynolds number effect and reduced relative surface roughness.
Centrifugal compressor centrifugal compressors.
Ingersoll rand s diverse and innovative products range from complete air compressor systems tools aro pumps material handling systems and more.
We also enhance productivity through solutions created by club car the global leader in golf and utility vehicles.
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.
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.
