Abstract
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a compressor having an impeller configured to rotate to pressurize a working fluid and direct pressurized working fluid through a diffuser passage of the compressor and an adjustable vane assembly. The adjustable vane assembly includes a vane configured to extend into the diffuser passage and to guide flow of the pressurized working fluid through the diffuser passage, and the adjustable vane assembly is actuatable to adjust a position of the vane within the diffuser passage.
Claims20
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- a compressor, comprising:
- an impeller configured to rotate to pressurize a working fluid and direct pressurized working fluid through a diffuser passage of the compressor;
- and
- an adjustable vane assembly comprising a vane configured to extend into the diffuser passage and to guide a flow of the pressurized working fluid through the diffuser passage, wherein the adjustable vane assembly is actuatable to adjust a position of the vane within the diffuser passage.
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- an adjustable vane assembly for a compressor, wherein the adjustable vane assembly comprises a plurality of vanes configured to extend into a diffuser passage of the compressor, and the adjustable vane assembly is actuatable to adjust a position of the plurality of vanes within the diffuser passage;
- and
- a control system configured to:
- determine a parameter associated with a flow of a working fluid through the compressor;
- and
- adjust the position of the plurality of vanes based on the parameter.
A compressor for a heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- an impeller configured to rotate to pressurize a working fluid and direct pressurized working fluid through a diffuser passage of the compressor;
- a base plate at least partially defining the diffuser passage;
- and
- an adjustable vane assembly comprising a plurality of vanes configured to extend through the base plate and into the diffuser passage, wherein the plurality of vanes is configured to guide flow of the pressurized working fluid through the diffuser passage, and the adjustable vane assembly is actuatable to adjust a position of the plurality of vanes relative to the diffuser passage.
