Centrifugal, Screw, or Absorption: Which Chiller Type Is Most Efficient for Your Facility?
Centrifugal, Screw, or Absorption: Which Chiller Type Is Most Efficient for Your Facility ?
Facility managers asking "which chiller type is most efficient?" usually discover the answer is frustratingly context - dependent.A centrifugal chiller achieving COP 6.5 at full load sounds impressive until you realize it operates at full load less than 10 % annually.A screw chiller with lower peak efficiency but excellent part - load performance might deliver better real - world results.
Efficiency Hack: Real-world efficiency isn't about peak numbers; it's about how the chiller performs during the 90% of the year it operates at partial load.
Understanding Efficiency Metrics
Comparison of Technologies
1. Centrifugal
Capacity: 150-6,000 TR
Peak Strategy: Highest efficiency at 100% load.
Best for: Stable, high - load environments like data centers.
2. Screw
Capacity: 70-600 TR
Peak Strategy: Superior part-load flexibility (10-100%).
Best for: Hotels or offices with variable daily loads.
3. BROAD Absorption
Capacity: 50-1,500 TR
Peak Strategy: Converts waste heat into free cooling.
Best for: Industrial sites with steam or exhaust gas.
Efficiency Decisions
| Factor | Centrifugal | Screw | BROAD VAM |
|---|---|---|---|
| Main Energy | Electricity | Electricity | Heat / Waste Heat |
| Part Load | Fair(risks surge) | Excellent | Stable Continuous |
| Op.Cost | High(Electricity) | Medium - High | Lowest(Waste Heat) |
