Refrigeration Cycle: Screw Compressors

September 8th, 2026

The most common type of screw compressor is the ‘rotary screw compressor’. This type of compressor utilizes two rotors which are often called helical screws. One screw is designated the “male” screw and the other is a “female” screw. Vapor is drawn into the screw and captured in the space between the screws. The screws are precisely […]

Refrigeration Cycle: Positive Displacement Compressors

August 25th, 2026

All positive displacement compressors generate pressure by drawing vapor into a compression chamber, sealing the chamber, and then shrinking the volume of the chamber. There are four common types of positive displacement compressors: 1) Screw Compressors 2) Reciprocating (or Piston) Compressors 3) Rotary Vane Compressors; and 4) Scroll Compressors. Screw compressors utilize meshing rotors to force […]
