Rotary Compressor
-
Operating Principle
The working fluid is compressed through the eccentric rotation of a roller and reciprocating motion of vanes within a cylindrical chamber. Volume reduction between components achieves gas compression.
-
Structural Features
- Simplified design with minimal moving parts (shaft, roller, vanes, cylinder)
- Oil-lubricated components for sealing and cooling
- Compact cylindrical housing with integrated inlet/outlet valves
- Direct eccentric drive mechanism
-
Advantages and Limitations
Advantages:
- High volumetric efficiency and compact size
- Low vibration and noise levels
- Balanced operation with minimal torque fluctuation
- Cost-effective manufacturing and maintenance
Limitations:
- Reduced efficiency under partial-load conditions
- Sensitivity to liquid refrigerant ingress ("slugging")
- Limited pressure ratio capability compared to reciprocating compressors
- Wear-prone vane-cylinder interface requiring precise lubrication
