There are five main types of compressors used in HVAC systems: rotary, scroll, screw, reciprocating, and centrifugal. Each type compresses gas or liquid with moving parts like pistons or impellers.
In air conditioning systems, rotary screw, vane, and reciprocating compressors are commonly found in small to medium-sized industries. Among these, screw compressors are known for their reliability and efficiency, while rotary compressors are preferred for their quiet operation and minimal vibration.
Reciprocating compressors, on the other hand, work by moving pistons up and down in a cylinder to compress air, similar to an engine. Each compressor type has its own advantages and applications in HVAC systems.
