Abstract:
One exemplary embodiment of this disclosure relates to a centrifugal refrigerant compressor system. The system includes a condenser, an evaporator, and an economizer between the condenser and the evaporator. The system further includes a centrifugal compressor having a first impeller and a second impeller downstream of the first impeller. The compressor includes at least one port. Fluid from a recirculation flow path and an economizer flow path is introduced into a main flow path of the compressor by way of the at least one port.
