New thermal management system for alternative refrigerants

Abstract

The European Union has expressed concerns on the usage of some materials that may have a long-term effect on the ecosystem, particularly PFAS (per- and polyfluoroalkyl substances), in keeping with its continuous commitment to sustainability and the ethical use of resources. Regulations on the use of these materials, especially those containing PFAS, are being worked on by the EU. As a company committed to sustainability, Volvo Cars is actively identifying and planning ahead for the use of substitutes in places where PFAS is utilized. The Thermal Management System is one important component that interacts with the EU-regulated refrigerant-containing refrigeration circuit. This has spurred a concentrated effort to investigate substitute refrigerants and design a suitable Thermal Management System based on them.
