Types of Compressers

Centrifugal compressors are similar to axial compressors in that they are rotating airfoil based compressors as shown in the adjacent figure. It should not be surprising that the first part of the centrifugal impeller looks very similar to an axial compressor.

An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged.

A rotary-screw compressor is a type of gas compressor that uses a rotary-type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as jackhammers.

A screw compressor is one where rotary helical screws are used to compress the air. These compressors are a replacement for the piston type compressors where vibrations and surges are more due to reciprocating action.

A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger) and as a vacuum pump.

Air Cooled Compressor Vs Water Cooled Compressor - posted in Industrial Professionals: hi everyone, i have a doubt regarding the type of cooling for a screw compressor.
