Visteon Corporation has launched a refrigerant system which it says furthers its goal of safe and reliable climate control solutions for the automotive market. The prototype was demonstrated with two test vehicles at the 2006 SAE Automotive Alternate Refrigerant Systems Symposium, June 27-29 in Scottsdale, Ariz. Automotive engineers and designers attending the show test drove two vehicles showcasing Visteon’s alternative refrigerant technology — one using natural refrigerant R744 and the other featuring the alternative low global warming potential refrigerant Fluid H. As a global automotive supplier, Visteon has in-depth climate systems expertise and broad development capabilities enabling the company to supply components and system solutions for either type of refrigerant. The Fluid H vehicle was developed by Visteon and its affiliate Halla Climate Control in close relationship with Hyundai. Visteon’s R744 system demonstrated production-ready component hardware. An R744 system uses carbon dioxide refrigerant instead of the R134a refrigerant found in today’s systems. R744 systems run at higher pressures but are more efficient under most conditions. The system can achieve up to a 20 percent reduction of incremental fuel consumption for air conditioner operation. Visteon’s R744 climate systems are a potential solution to meet upcoming European and worldwide legislation on greenhouse gases. “Visteon is recognized as a leader in R744 development, and we continue to investigate further solutions for potential advance refrigerants,” explained Joy Greenway, vice president of Visteon’s climate group. “Our objective is to deliver the most efficient and reliable solution to meet current and future environmental legislation regarding automotive refrigerants.” The SAE 2006 Automotive Alternate Refrigerant Systems Symposium brought together industry engineers to focus on mobile heating and cooling technologies. Attendees learned about effective refrigerant system control strategy, and updates on SAE standards covering system design, service equipment and technician service procedures for mobile air conditioning systems. Visteon Corporation is a 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.
