General Information
The working principle of the Rotary Compressor
Rotary compressors are ‘high pressure shell’ type compressors. The suction on these compressors
is taken directly into the compression chamber. Gas compressed in the compression chamber is
discharged into the compressor casing. It should be noted that from a cold start-up, high pressure shell
type compressors take longer to reach their normal operating pressure in the compressor shell. This
is partly due to the larger volume of the compressor casing and partly as a result of refrigerant being
trapped in the oil. Any refrigerant in the oil has to completely evaporate before condensing pressure can
reach its operating level.

Tecumseh Europe with its long experience of compressor development has introduced
a range of rotary compressors for air conditioning and commercial refrigeration.
This operating manual has been designed to help you correctly install this compressor
range in your applications.
