How do reciprocating, screw, scroll, and centrifugal compressors compare?³
Refrigeration compressors come in various types, each suited for specific applications. The four most common types are reciprocating, screw, scroll, and centrifugal compressors. They differ in design, working principles, and efficiency levels.
Key Differences Between Compressor Types：
| Compressor Type | Working Principle | Efficiency | Best for |
| Reciprocating | Uses pistons to compress refrigerant | Moderate | Small to medium cooling loads |
| Screw | Rotors compress refrigerant continuously | High | Large industrial refrigeration systems |
| Scroll | Two interlocking scrolls compress refrigerant | High | Commercial refrigeration and HVAC |
| Centrifugal | Uses centrifugal force to compress refrigerant | Very High | Large-scale cooling applications |
Each type offers unique advantages depending on the operational requirements, energy efficiency, and maintenance needs.
