Manifold configurations with high reliability for staged modulations
In a Performer® SM / SY / SZ scroll compressor, the compression is performed by two scroll elements located in the upper part of the compressor.
Suction gas enters the compressor at the suction connection. As all of the gas fl ows around and through the electrical motor, thus ensuring
complete motor cooling in all applications, oil droplets separate and fall into the oil sump. After exiting the electrical motor, the gas enters the
scroll elements where compression takes place.
Ultimately, the discharge gas leaves the compressor at the discharge connection.
The figure below illustrates the entire compression process. The centre of the orbiting scroll (in grey) traces a circular path around the centre of
the fi xed scroll (in black). This movement creates symmetrical compression pockets between the two scroll elements. Low-pressure suction gas is
trapped within each crescent-shaped pocket as it gets formed; continuous motion of the orbiting scroll serves to seal the pocket, which decreases
in volume as the pocket moves towards the centre of the scroll set increasing the gas pressure. Maximum compression is achieved once a pocket
reaches the centre where the discharge port is located; this stage occurs after three complete orbits. Compression is a continuous process: the
scroll movement is suction, compression and discharge all at the same time.
