Type of Refrigerant Compressor

Reciprocating Compressors:

Type of Refrigerant Compressors, Compressors in which vapor refrigerant is rotated by the piston forward and backward is called the piston speed. These compressors are used for refrigerants with relatively low volumes per kilogram and a large differential pressure, such as ammonia, R-12,22, and methyl chloride. Reciprocating compressors are available in smaller sizes of 1/12 kW than those used in small household refrigerators and up to about 150 kW for large-capacity installations.

In general use, two types of rotating compressors are single acting vertical compressors and double horizontal horizontal compressors.

2. Screw compressors:

Screw compressors consist of a pair of meshing screws, between which the refrigerant is compressed. They can produce high pressures for small amounts of gas. They consume less power than reciprocating compressors and are being widely used. It can be used with refrigerants such as R12, R22, and others.

3. Rotary Compressors:

Rotary compressors have two rotating elements like gears, between which refrigerant is compressed. These compressors can pump refrigerants at low or moderate condensing pressures. Since they can handle small amounts of gas and produce low pressure, they are used in fewer applications.

4. Centrifugal compressor:

Centrifugal compressors include impellers or blowers that can handle large amounts of gas but at relatively low condensing pressures. It is suitable for working with refrigerators like R-11, R-113 etc.

4. Scroll compressors:

The scroll compressor consists of two interleaved scrolls, one of which is fixed and the other circled eccentrically without twisting. During its motion small gaps are formed between the scrolls where the refrigerant becomes compressed. Scrolls can have different shapes such as an Involve, Archmedian Spiral or Hybrid Curve. In another arrangement both scrolls can rotate eccentrically to produce compression.
