Horizontal Scroll Compressors

Horizontal
Scroll Compressors
for TRANSPORT Air Conditioning Application
Printed in Japan (H) HR-E592 Sep. 2010

Exclusive design for transport air conditioning
thanks to long experience and a wealth of
know-how since 1966.
Compressor Supplied (Applications)
Thanks to compact size and lighter weight,
Hitachi horizontal scroll compressors are suitable for
the applications which installation space and weight of
the air conditioner are limited, like metro and LRT projects.

Advantages
High Efficiency
Efficiency has been improved by minimizing gas leaks
during compression.
The gas leakage can be minimized because the pressure
difference between the 2 compression pockets next to
each other is less than the total pressure difference, which
takes intake pressure from the outlet pressure.
Also, the compressed gas does not expand, as the outlet
opening is not connected to the low-pressure side.
High Reliability
Orbiting scroll is supported by intermediate pressure
in high pressure chamber, which can reduce sliding
parts and realize higher reliability.
Higher resistance to ON/OFF operation thanks to less oil
foaming.
Less fluctuation of temperature and pressure for discharge gas.
Suitable for variable speed control, since oil is
supplied to compression room by pressure difference.
High Pressure Type Compressor
Fixed Scroll
Low noise and Low Vibration
As intake, compression and emission are continuously
carried out as a series of movements, the scroll compressor
has low noise and low vibration, plus the torque after
compression is nearly the same as other compressors.
Size & Weight
Thanks to compact design, adoption of Hitachi horizontal
scroll compressors realizes space-saving. Especially, the
HVAC has become thinner. They are mainly used in Metro
and LRT projects,where installation space is limited.
Reducing the weight of the air conditioner by adopting
HITACHI horizontal scroll compressors can realize
power-saving.
