Summary of Advantages and Disadvantages of Various Chillers

1. Reciprocating Chiller

Advantages:

1. Simple materials, easy processing, low cost.
2. Simple system design, easy lubrication, no exhaust device required.
3. Multi-cylinder, high-speed design improves performance.

Disadvantages:

1. Many components and wear parts, complex maintenance, high costs.
2. Low compression ratio, small cooling capacity per unit.
3. Poor part-load performance, lacks stepless regulation.
4. Reciprocating motion causes significant vibration.
5. High weight per unit cooling capacity.

2. Screw Chiller

Advantages:

1. Simple structure, fewer moving parts, low failure rate, long lifespan.
2. Smooth rotary motion, low noise, minimal vibration.
3. High compression ratio (up to 20), high EER.
4. Stepless regulation (10%-100%), high efficiency at partial loads.
5. Compact, lightweight, suitable for large vertical units.
6. Resistant to liquid slugging.
7. Operates under positive pressure, preventing external air corrosion.

Disadvantages:

1. More expensive than reciprocating chillers.
2. Smaller capacity and lower speed than centrifugal chillers.
3. Complex lubrication system, higher oil consumption.
4. Larger units produce more noise than centrifugal chillers.
5. Requires high precision in manufacturing and assembly.

3. Centrifugal Chiller

Advantages:

1. High-speed impeller enables large air volume and high capacity.
2. Fewer wear parts, reliable operation, compact structure.
3. Low vibration and noise.
4. Excellent heat transfer due to oil-free refrigerant.
5. High EER (up to 6.99 theoretically).
6. Stepless regulation from 10% to 100%.

Disadvantages:

1. Low-load conditions may cause “surge” instability.
2. High material strength and precision manufacturing required.
3. Efficiency drops sharply if operating outside design conditions.
4. Operates under negative pressure, increasing risk of air ingress and corrosion.

4. Modular Chiller

Advantages:

1. Improved design based on reciprocating and screw chillers, combining multiple chiller units.
2. Compact, lightweight, low height, minimal space requirements.
3. Easy installation, no need for pre-installed openings, ideal for retrofits.

Disadvantages:

1. More expensive than traditional systems.
2. Maximum recommended modules: 8 units.

5. Water Source Heat Pump Chiller

Advantages:

1. Energy-saving, allows heat recovery in winter.
2. Utilizes natural heat sources.
3. High energy efficiency.
4. Easy installation, low maintenance costs.
5. Flexible application, easy to regulate.

Disadvantages:

1. Limited fresh air utilization during transitional seasons.
2. Higher noise levels.
