Scroll compression principle
Scroll compressor
components
The motor stator is rigidly attached to the shell.
The rotor is shrink-t onto the eccentric shaft. The
shaft is supported by two bearings, one in the
crankcase and the second below the motor.

Scroll compression principle
The scroll compression
process
SUCTION
The entire scroll compression process is illustrated
below. The centre of the orbiting scroll traces a
circular path around the centre of the xed scroll.
This movement creates compression pockets
between 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
simultaneously, another is being discharged.

Performance
Danfoss Heat Pump scroll compressors are
manufactured using the most advanced
machining, assembly, and process control
techniques. In design of both the compressor
The Danfoss Heat Pump scroll compressor

and process control were rst priority. The result
is a highly ecient product with the highest
reliability obtainable, and a low sound level.
it's early commissioning. A seventy-two hour
run-in is recommended to meet performance
expectations.
