Scroll compression principle

  1. Compressor sucks air through air inlet located at outer scroll.
  2. Compression chamber goes smaller with rotary movement and trapped air is compressed.
  3. Compression chamber becomes minimum volume at the center of the scroll and air is pumped out through air outlet located at the center of scroll.
  4. These, suction, compression & discharging, process is repeated continuously.
