What does centrifugal compressor means and how does it works

The centrifugal compressor is a kind of dynamic compressor or simply a turbo compressor which constitutes with a radial design. These compressors work at a constant pressure but its performance changes with the external conditions like a change in the inlet temperatures.

One can see its significant applications in the food & beverage industry, oil refineries, natural gas processing, refrigeration, air conditioning etc.

The centrifugal compressor achieves a rise in pressure by adding significant velocity to the continuous flow of the fluid through the impeller. In this device the energy transfers from the sets of rotating blades to the working fluid (Air). It gets the designation of centrifugal as the gas flows in the radial direction.

In result, the energy transfer is due to the change in the centrifugal forces acting on the gas.  They have high flow capacity, good reliability and require less maintenance in comparison to reciprocating compressors.
