High efficiency, high reliability,
small size, light-weight, low vibration and
low noise have been key demands of the present
age in the air conditioning market. |

WORLD FIRST
IN SCROLL COMPRESSORS |
| |
Hitachi scroll compressor
is made with Hitachi's technology it
was developed and manufactured in 1983
as the world's first scroll compressor. |

FEWER PARTS |
| |
The compression mechanism
of a scroll compressor consists of only
five main parts. |
| |
|
| |
|
| |
|
| |
HIGH EFFICIENCY |
| |
High efficiency due to
minimal gas leakage during compression.
The pressure difference between the
two neighbouring compression pockets
is smaller than the total pressure difference
of the discharge pressure minus the
suction pressure; resulting in minimal
leakage. Since the discharge port is
not connected to the low-pressure side,
the compressed gas does not expand. |

|
| |
|
| |
|
| |
LOW SOUND, LOW
VIBRATION |
| |
Suction, compression
and discharge processes are simultaneously
and continuously performed and therefore,
the vibration and noise levels are low
and the torque of the scroll compressor
varies little in comparison with the
other types of compressors. |
| |
|
| |
|
| |
|
|
|
| |
|
HIGH RELIABILITY |
| |
As there is no
suction valve of discharge valve mounted,
the scroll compressor is more efficient, quieter,
and more reliable. |
|
| |
| |
| |
|
WIDE OPERATING RANGE |
| |
Greater efficiency
is achieved over a wide range of operating
pressure ratios. The volumetric efficiency
has improved remarkably, especially in the
high-pressure ratio range. Smoother operation
makes it possible to introduce the scroll
compressor at high rotational speeds. |
