Types of Compressors

Types of Compressors Points : types of compressors, reciprocating compressors, centrifugal compressors, rotary compressors, screw type compressors There are four types of compressors used in refrigeration system.
(i) Reciprocating compressors.
(ii) Centrifugal compressors
(iii) Rotary compressors.
(iv) Screw type compressors.

The reciprocating compressors find application and are very suitable for refrigerants which require relatively small-displacement volumes and high condensing pressures. The refrigerant like R-12, R-22, R-717 etc. fall in this group.

The centrifugal compressors find application and are very suitable for refrigerants which require relatively large displacement volumes and low condensing pressures. The refrigerants like R- 11, R- 113 etc. fall in this group. R- 12 is also employed with centrifugal compressors for large ‘capacity jobs and low temperature applications.

The rotary compressors find application and are very- suitable for refrigerants having moderate or low condensing. pressures. Refrigerants like R-21 and R-114 fall in this group. This is mainly used for domestic refrigerants.
