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 […]

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 […]

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 […]
