Scroll compressors are a type of positive displacement compressor commonly used in various applications, including air conditioning equipment, refrigeration units, and industrial processes. Before we dive into the pros and cons, let’s understand how scroll compressors work:

Design: A scroll compressor consists of two spiral “scrolls.” Scroll 1 remains immobile and serves as the compression site, while scroll 2 orbits inside scroll 1 due to the crankshaft’s motion. Compression occurs as the inner scroll moves within the immobile scroll.

Now, let’s explore the advantages and disadvantages of scroll compressors:

Advantages:

1. Efficiency:

   • Scroll compressors minimize waste buildup. Every ounce of air that enters the scrolls leaves the compression area, ensuring efficient performance.

   • The orbital movement within the scrolls reduces particle size during compression, resulting in better efficiency.

2. Low Noise Levels:

   • The simple design of scroll compressors allows them to operate at an almost imperceptible volume.

   • Their low vibration rates lead to a minimal hum, comparable to the noise level in a library.

   • This makes scroll compressors suitable for installation in noise-sensitive locations.

Disadvantages:

1. Manufacturing Cost:

   • Scroll compressors involve high-end machinery and precise centering assembly technology, which increases manufacturing costs.

   • Consequently, the initial purchase price of scroll compressors tends to be higher than other compressor types.

2. Water-Cooled Scroll Chillers:

   • In the context of chillers, scroll compressors are often used in water-cooled systems.

   • Pros: Longer lifespan and well-suited for constant cooling needs.

   • Cons: Require a constant water supply and are more expensive than air-cooled scroll chillers3

3. Air-Cooled Scroll Chillers:

   • In the context of chillers, scroll compressors are also used in Air-cooled systems.

   • Pros: Longer lifespan and well-suited for constant cooling needs.

   • Cons: Require a large open Area.
