Visteon's Scroll Compressor Delivers Cooling and Energy Efficiencies

    PALMELA, Portugal, March 26 The scroll compressor produced
by Visteon Corporation at its dedicated facility in Palmela,
Portugal, delivers major benefits over conventional, piston-driven
compressors.
    
    Visteon's scroll compressor design is based on the principle of circle
involutes or scrolls, which revolve around each other in a "rolling" motion.
Pressure loads supported by ball bearings create far less friction on internal
components when compared to piston-driven compressors.  By reducing the need
for hydrodynamic lubrication that is required to reduce friction at internal
contact points, the scroll compressor provides an inherently smoother
operation and improved thermodynamic efficiency.

    The compressor is the engine behind any refrigeration or air conditioning
system and the way in which it operates will play a large part in determining
the effectiveness and efficiency of the system as a whole.  The main benefit
of the Visteon scroll compressor is a quieter, smoother and more efficient
operation, along with greater reliability and durability.

    "The scroll compressor will run between 30 percent and 100 percent
capacity reducing engine 'surge' or 'stumble' which is experienced with some
vehicle air conditioning systems," said Sunil Bilolikar, Compressor Operations
Manager at Visteon's Palmela plant.  "The compressor also provides a smoother
transition when the air conditioning is switched from on to off.  At the same
time, the compressor helps minimize the effects of air conditioning on power
consumption at typical road speeds."

    The scroll compressor is capable of running for extended periods of time
at 10,000 RPM (revolutions per minute) and exceeds OEM's requirement of
reliable service over 10 years or 240,000 kilometers.
