Refrigeration Cycle: Reciprocating Compressors

September 1st, 2026

Reciprocating compressors are the most common type of refrigeration compressor. The design of reciprocating compressors since their adoption in the mid-1800s is similar to that of a car engine. In a “recip”, compression is accomplished in the same manner as a bike pump. When the piston is pulled to one end, the cylinder volume increases and […]

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 […]
