GUIDELINES
Performer® Heat Pump scroll compressors are
manufactured using the most advanced machin-
ing, assembly, and process control techniques. In
design of both the compressor and the factory,
very high standards of reliability and process con-
trol were fi rst priority. The result is a highly effi
-
cient product with the highest reliability obtain-
able, and a low sound level.
The Performer® Heat Pump scroll compressor
referenced in this guide is a fully compliant scroll
and actually improves with run time in it's early
commissioning. A seventy-two hour run-in is rec-
ommended to meet performance expectations.
The entire scroll compression process is illustrat-
ed below. The centre of the orbiting scroll traces a
circular path around the centre of the fi xed scroll.
This movement creates compression pockets be-
tween the two scroll elements.
Low pressure suction gas is trapped within each
crescent-shaped pocket as it forms; 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, with
corresponding increase in gas pressure. Maximum
compression is achieved, as the pocket reaches
the discharge port at the centre.
Scroll compression is a continuous process: when
one pocket of gas is being compressed during the
second orbit, another gas quantity enters a new
pocket formed at the periphery, and simultane-
ously, another is being discharged.
