Le problème du réchauffement climatique actuel conduit au renforcement des règlementations environnementales. Ainsi, le domaine du génie climatique est affecté par ces évolutions réglementaires, ce qui impose le passage à une nouvelle génération de réfrigérants à plus bas impact environnemental. Dans cette thèse, ce sujet est étudié dans le cas des groupes refroidisseurs d’eau utilisant le R-410A qui est visé par la réglementation. Mais, résoudre ce problème ne s’arrête pas au simple changement du réfrigérant par un autre à plus bas GWP ; il faut que la transition soit accompagnée par une amélioration ou un maintien de la puissance frigorifique et de la performance énergétique du système par crainte d’avoir un effet environnemental inverse ...
