Scroll Compressors

Scroll compressors are a popular type of positive displacement compressor used extensively in air conditioning, refrigeration, and heat pump applications. Known for their quiet operation, high efficiency, and reliability, scroll compressors have become a standard in residential, commercial, and light industrial HVACR systems.

How Scroll Compressors Work

Scroll compressors use two interleaved spiral-shaped scrolls:

  • One scroll is stationary, fixed in place.
  • The other scroll orbits (moves in a circular path without rotating) around the fixed scroll.

As the orbiting scroll moves, it traps refrigerant in crescent-shaped pockets between the scrolls and gradually pushes it toward the center, where it is compressed and discharged. This continuous, smooth compression process leads to efficient and quiet operation with minimal pulsations.

Key Features & Advantages

  • High Efficiency
    Fewer moving parts and continuous compression result in lower energy consumption compared to reciprocating compressors.
  • Quiet Operation
    The smooth, rolling action reduces vibration and noise, making scroll compressors ideal for noise-sensitive environments.
  • Reliability
    Durable design with fewer components reduces wear and tear, extending operational life.
  • Compact Size
    Scroll compressors are generally smaller and lighter than other compressor types of similar capacity.
  • High Tolerance to Liquid Slugging
    Scroll compressors can handle occasional liquid refrigerant return better than many other designs.
