Definition:The heart of a mechanical refrigeration system. Compresses refrigerant vapor from low pressure (evaporator) to high pressure (condenser), enabling the refrigeration cycle.
Types::
- **Reciprocating**: Piston-based, common in small TRUs
- **Scroll**: Spiral compression, quieter operation, medium capacity
- **Screw**: Twin rotating screws, high capacity, industrial applications
- **Centrifugal**: High-speed impeller, very large capacity systems
Why It Matters:: Compressor type and size determine system capacity, efficiency, reliability, and maintenance requirements. Altitude significantly affects compressor performance in Gauteng.
