  • 32 Accesses

Abstract

The environment-friendly A/C system by Behr being introduced in 2003 is more powerful than a conventional system. However, the requirements have changed: Instead of a higher cooling performance, the same performance of a R744 system is expected in comparison to a state-of-the-art system with R134a, with minimal additional costs. The second generation R744 system fulfils these requirements.
