Compressor Types
This period is devoted to the discussion of the different types of compressors.
There are primarily four types of compressors used in the air-conditioning
industry: reciprocating, scroll, helical-rotary (or screw), and centrifugal.
The traditional reciprocating compressor has been used in the industry for
decades. It contains cylinders, pistons, rods, a crankshaft, and valves, similar to
an automobile engine. Refrigerant is drawn into the cylinders on the
downstroke of the piston and compressed on the upstroke.
Scroll and helical-rotary (or screw) compressors have become more
common, replacing the reciprocating compressor in most applications due to
their improved reliability and efficiency.
These three types of compressors (reciprocating, scroll, and helical-rotary) all
work on the principle of trapping the refrigerant vapor and compressing it by
