Abstract

La présente invention concerne l'utilisation d'un ou plusieurs éjecteurs à deux phases activés par du fluide frigorigène mis sous pression, ledit ou lesdits éjecteurs à deux phases sont situés stratégiquement dans le cycle du système de réfrigération de façon à fournir une partie de l'effet de compression requis pour la charge de réfrigération, ce qui permet de soulager dans une partie de ses fonctions le compresseur mécanique classique, augmentant ainsi l'efficacité de cycle globale du système de réfrigération.
