The fixed displacement
compressors compress refrigerant in accordance with the engine
rotation.
In the scroll
fixed displacement compressor, a movable scroll rotates to
change the volume of space between the movable scroll and the
fixed scroll, compressing the refrigerant. |
Technology
In 1997 the
first scroll fixed displacement compressor that adopted a centrifugal oil
separator to reduce the amount of oil contained in circulating
refrigerant, improving the efficiency of the air conditioning system was
launched by Denso.
Benefits and Features
Small size and light
weight
housing was improved , giving it a thinner wall while maintaining its strength,
making it smaller and lighter.
The fixed scroll
functions as a compression chamber wall, resulting in an even smaller
and lighter compressor.
High compressor efficiency
and high durability
The oil separator
removes most of the oil from the refrigerant when it is discharged
from the compressor. That oil is then supplied to the compressor's
sliding parts, maintaining lubrication of the compressor and
increasing efficiency as well as durability.
The optimized shape of
the scrolls further improves the compressor efficiency.
The reduced number of
parts in the sliding section, including a simple
rotation-preventive
mechanism, reduces energy loss caused by sliding.
Low noise and vibration
The reduced number of
parts in the sliding section reduces mechanical noise.
The optimized housing
shape reduces the pulsation of refrigerant discharged from the
compressor.
