Working Principle of Compressor and its Types

Basically, compressor in refrigeration system have following main function
1. Remove low temperature and low pressure refrigerant vapors from cooling coil through suction line.
2. Compress refrigerant vapors by increasing the pressure and temperature resulting in an increase of boiling point of refrigerant.
3. Discharge the refrigerant vapors of high temperature and pressure to condenser through discharge line.
Compression of refrigerant gas may be accomplished by any one of several different means such as positive displacement (reciprocating, rotary, gear types) and centrifugal (centrifugal compressor). The common type of compressors in use are
1. Reciprocating compressor
2. Rotary compressor
3. Centrifugal compressor
4. Screw compressor
5. Scroll compressor Read more
