Components
Compressor
The centrifugal compressor uses the principle of dynamic compression,
which involves converting energy from one form to another, to increase the
pressure and temperature of the refrigerant. It converts kinetic energy to static
energy.
The core component of a centrifugal compressor is the rotating impeller. The
center, or eye, of the impeller is fitted with blades that draw refrigerant vapor
into radial passages that are internal to the impeller body.
