Visteon's latest application-ready R744 climate system consumes up
to 25 percent less fuel than conventional R134a systems and enables
a reduction of CO2 tailpipe emissions of up to 7g/km while
operating the air-conditioning system. KERPEN, Germany, Sept. 7,
2007 /PRNewswire/ -- As a recognized leader of R744 automotive
thermal management solutions, Visteon Corporation (NYSE:VC) has
demonstrated enhanced system performance through continuous
improvements on both the system and component level. The global
company has designed a system set to improve fuel economy in future
vehicles. (Logo:

latest generation R744 system consumes up to 25 percent less
incremental fuel compared to conventional R134a systems. The
efficient operation helps to reduce the overall fuel consumption of
the vehicle by approximately 0.3 liter per 100 km at the same
cooling performance as traditional systems at an ambient
temperature of 25 degrees C, leading to a reduction of CO2 tailpipe
emission by 7g/km. Pioneering the development of R744 systems,
Visteon has delivered more than 30 prototype vehicles with R744 air
conditioning systems across different platforms to more than 12
vehicle manufacturers. These vehicles and Visteon's own test fleet
have been undergoing extensive trials in hot and cold climates. "We
have been developing R744 climate systems and components since 1999
and have achieved significant improvements in both system
efficiency and cooling performance," explains Nurdal Kucukkaya,
Visteon vice president. "Today we can offer a production-ready and
complete R744 climate system, which not only meets upcoming
European legislation on greenhouse gases, but also helps our
customers improve fuel economy." Visteon's in-depth system
expertise and state-of-the-art development tools were applied to
optimize the design of components and fully utilize the favorable
thermodynamic properties of the natural refrigerant R744. By
designing standardized and compact components, Visteon has
developed a package and cost efficient system, which can be
integrated in parallel to the phaseout of existing R134a systems.
As a part of the system, Visteon has designed a new and very robust
fitting technology called VisCO2nnect. Unlike conventional metal
seal fittings, VisCO2nnect has a patented design which assures the
required level of pressure and supports easy assembly and
serviceability. "With our innovative fitting technology we have
been able to demonstrate a high level of system competence," said
Kucukkaya. "Our customers have confirmed that VisCO2nnect has
redefined industry standards in R744 fluid transport development."
Visteon also has developed a range of compressors to support all
vehicle classes from small and compact to luxury vehicles. All
compressors have been through extensive component and vehicle
testing. In addition, Visteon is working on future R744
applications supporting hybrid vehicles. The key component is a
compact designed electrical compressor, which allows for efficient
package utilization and integration in parallel to conventional
compressors. Visteon is actively working with various OEMs to
develop a modular compressor, which can be easily adapted to mild
and full hybrid applications. Visteon Corporation is a leading
global automotive supplier that designs, engineers and manufactures
innovative climate, interior, electronic and lighting products for
vehicle manufacturers, and also provides a range of products and
services to aftermarket customers. With corporate offices in Van
Buren Township, Mich. (U.S.); Shanghai, China; and Kerpen, Germany;
the company has facilities in 26 countries and employs
approximately 43,000 people.
