Compressor type
- Dec 02, 2016 -

Compressor refrigeration system was seen as the heart of best performance of compressor characteristic terms known as "vapor pump". Responsibilities assume the compressor is to raise the pressure, increase the suction pressure to discharge pressure.

Compression ratio is a technical representation of pressure difference, which means high side pressure divided by the absolute pressure of the low-voltage side. Compression ratio of absolute pressure value must be used. To avoid compression ratio calculated value negative, absolute pressure must be used when calculating the pressure ratio, rather than the gauge pressure. Absolute pressure value in order to make the compression ratio is used to calculate the value is positive, it makes sense.

The compressor used in refrigeration and air conditioning industry has 5 major types: reciprocating, screw, Rotary, scroll compressors and centrifugal, reciprocating is small and medium-scale commercial refrigeration system up to a compressor. Screw-type compressor mainly for large commercial and industrial systems. Rotary compressors, scroll compressors are mainly used for domestic and small commercial air-conditioning units, centrifugal compressors are widely used in air conditioning systems of large buildings.

Reciprocating compressor is generally based on the compressor shell and drive mechanism set up classifications. According to shell forms, open and enclosed semi-hermetic compressor. Enclosed we mean the compressor is set in a shell.
