INTERIORS: SAE committee to work with VDA on R-744 A/C standards

摘要

R-1234yf may be the choice of most car manufacturers worldwide as the new low-global-warming (LGW) A/C refrigerant to replace R-134a, but as many in the industry have learned, there are several German automakers who have had second thoughts. They have reactivated a project to use R-744 (carbon dioxide as a refrigerant) instead, and development assignments to members were distributed by VDA (German association of the automotive industry). The leadership assignments went to vehicle manufacturers; Tier 1 suppliers also are participating.
