4.2.4 Scroll Compressor
● Reliable Mechanism for Low Vibration and Low Sound
(1) The rotating direction is denite.
(2) The pressure inside of the compressor housing is high pressure, and the surface temperature of the
compressor housing is 140
o
F (60
o
C) to 230
o
F (110
o
C).
● Principle of Compression
(1) Gas enter the compressor from top at the suction inlet.
(2) Hot gas leaves the compressor from the side mounted discharge gas
outlet.
(3) Compressor starts at the beginning of the scroll at a lower pressure,
and continues to the outer edge of the scroll where the pressure
is greatest and discharged through the side discharge gas port at
the center of the compressor.
(4) The above procedures (Suction Compression Discharge) are
repeated continuously.
