Management of connections for passenger car air-conditioning using CO2

Markus Goebel; Martin Lechner

An EU regulation prescribes that from 2011, with a transition period up to 2017, all new passenger cars and light commercial vehicles must contain an environmentally-friendly refrigerant. The German car manufacturers have decided in favor of carbon dioxide “CO2” (R744) as the new natural refrigerant for vehicle air-conditioning systems. In addition to environmental friendliness, CO2 air-conditioning systems also offer higher efficiency than current R134a systems. For a better management of connections Voss Automotive developed new connection systems and sealing design, which allow the pressures four times higher and operating temperatures twice as high in a CO2 air-conditioning system.

Verbindungsmanagement fuer die CO2-Klimatisierung in Pkw

Markus Goebel; Martin Lechner

Eine EU-Regelung schreibt vor, dass ab dem Jahr 2011, mit einer Ubergangsfrist bis zum Jahr 2017, alle neuen Pkw und leichten Nutzfahrzeuge mit einem umweltfreundlichen Kaltemittel ausgestattet werden mussen. Die deutschen Automobilhersteller haben sich fur Kohlendioxid „CO2“ (R744) als neues naturliches Kaltemittel in Fahrzeugklimaanlagen entschieden. Neben der Umweltfreundlichkeit bieten CO2-Klimaanlagen auch einen hoheren Wirkungsgrad als aktuelle R134a-Anlagen. Voss Automotive hat fur ein verbessertes Verbindungsmanagement neue Verbindungssysteme und Dichtungsformen entwickelt, die die vierfach hoheren Drucke und doppelt so hohen Betriebstemperaturen in einer CO2-Klimaanlage erlauben.
