In one embodiment, the device utilizes a nozzle (300) that installs into the discharge opening (388) on a volute (384) of a centrifugal compressor (302). Actuation of the nozzle (300) modifies a flow area (318) through which the working fluid exits the centrifugal compressor (302). The change in the flow area increases the velocity of the working fluid, without the need to change the operating speed and/or other operating parameters of the centrifugal compressor (302).

These embodiments deploy a flow sensor to identify the direction of flow for a working fluid that transits the stages of the compressor device. In one embodiment, the flow sensor generates a signal, which a controller processes to align a variable diffuser vane with the direction of flow of the working fluid. This configuration preempts the operational difficulties of previous designs by providing independent control over the diffuser vanes in the individual stages of the multi-stage compressor device.
Embodiments of a system and method manipulate the position of inlet guide vanes and the drive speed for optimizing performance of a compressor device (e.g., a centrifugal compressor).

In one embodiment, the system and method measure input power with the diffuser vanes at a first position (302) and a second position (304). Changes in the input power will identify other positions for the diffuser vanes that optimize performance of the compressor device, e.g., to reduce power consumption and to achieve and maintain peak compressor efficiency within the entire operating envelope of the compressor device.
Embodiments of a diffuser vane comprise a vane body with a leading edge and a trialing edge that can rotate about the leading edge to improve performance of a compressor device. This configuration maintains the position of the leading edge on the diffuser vane relative to the orientation of the working fluid.
