En raison de la distillation, un bon nombre de concepteurs est concerné par l'utilisation des mélanges de frigorigène de nature zéotropiques La difficulté principale vient de la différence bien connue de composition entre les deux phases liquide et vapeur dans un mélange non-azéotrope. Dans ce travail, l'impact de tels effets a été analysé en se basant sur essais menés sur une pompe à chaleur domestique fonctionnant en mode chauffage ainsi qu'en mode rafraîchissement. Les tests ont été effectués successivement avec du R-407C en composition nominale, puis avec un mélange « riche » de 33%R32-25%R125-42%R134a et enfin avec un mélange « pauvre » de 13%R32- 25%R125-62%R134a. L'analyse thermodynamique (puissance frigorifique, COP, EER, différents rendements du compresseur, ?) déduite des mesures expérimentales, confirme globalement les résultats théoriques : la dégradation des performances de la machine reste limitée même pour une telle variation de composition, La diminution maximum du COP a été enregistrée pour le mélange dont la fraction massique du R-32 est plus élevée.
