How Do Scroll Compressors Compare to Piston Compressors?

When comparing scroll compressors to piston compressors, several factors come into play. Here’s a detailed explanation:

1. Design and Operation:

Scroll compressors and piston compressors have different designs and operating principles. Scroll compressors utilize two interlocking spiral-shaped scrolls to compress the refrigerant or gas. The scroll motion creates a continuous compression process with minimal pulsations. On the other hand, piston compressors use a reciprocating piston driven by a crankshaft to compress the refrigerant or gas. The piston motion generates pulsations during compression.

2. Efficiency:

Scroll compressors are generally more efficient than piston compressors. The continuous compression process of scroll compressors, along with minimal clearance volume, reduces energy losses and improves overall efficiency. In contrast, piston compressors experience more energy losses due to the reciprocating motion and clearance volume. Scroll compressors are known for higher part load efficiency, especially when equipped with variable speed drive (VSD) technology.

3. Noise and Vibration:

Scroll compressors tend to operate with lower noise and vibration levels compared to piston compressors. The interlocking scroll motion in scroll compressors creates a smooth compression process with reduced pulsations, resulting in quieter operation. Piston compressors, on the other hand, generate more noise and vibration due to the reciprocating motion and pulsations during compression.

4. Size and Compactness:

Scroll compressors are generally more compact than piston compressors. The absence of reciprocating parts in scroll compressors allows for a more compact design, making them suitable for applications where space is limited. Piston compressors, with their reciprocating motion and larger size, require more space for installation.

5. Reliability and Maintenance:

Scroll compressors offer enhanced reliability and require less maintenance compared to piston compressors. Scroll compressors have fewer moving parts, such as valves and piston rings, which reduces the chances of failure or breakdown. Piston compressors, with their more complex design and wearing components, may require more frequent maintenance and have a higher probability of mechanical issues.

6. Capacity and Load Handling:

Piston compressors are generally more suitable for applications with varying load demands. Piston compressors can handle a wider range of capacities and adapt to varying cooling or heating loads. Scroll compressors, while capable of modulation with VSD, may have limitations in extreme load turndown situations.

7. Cost:

The cost of scroll compressors and piston compressors can vary depending on factors such as capacity, brand, and features. In general, scroll compressors tend to be more expensive than piston compressors due to their higher efficiency, quieter operation, and compactness. However, the price difference may vary based on specific models and market conditions.

It’s important to note that the suitability of scroll compressors or piston compressors depends on the specific application requirements, load profile, and other factors. Both types of compressors have their advantages and disadvantages, and the choice between them should be based on a thorough analysis of the application needs.

In summary, scroll compressors offer advantages such as higher efficiency, quieter operation, compactness, and enhanced reliability. Piston compressors, on the other hand, may be more suitable for applications with varying load demands.
