11.1.2 Vane compressors

The operation of vane compressors is based on the rotation of the rotor and the reduction of the space available for the refrigerant trapped between the vanes. The contact between the vanes and the stator is sealed by the centrifugal force applied to the vanes at high speed. The capacity between two vanes is variable. The gas is sucked in by the increase in volume before the inlet tube. The gas is then trapped between two vanes and conveyed towards the outlet tube. The volume is reduced in this zone and the gas is released into the outlet pipe. 11.1.3 The compressor ports As a general rule the compressor ports can be distinguished based on their diameters g Low Pressure (Suction port): Big diameter g High Pressure (Discharge port): Small diameter Nevertheless some compressor does not follow this rule, the port functions are then indicated by letters g S for Suction g D for Discharge

High pressure (Discharge port) Small diameter

Low pressure (Suction port) Big diameter

Suction port (low pressure)

Discharge port (high pressure)
