Abstract

Ce dispositif à cycle de réfrigération (100) comprend : un compresseur ; une vanne à quatre voies ; un premier échangeur de chaleur (3) comprenant une première section d'entrée / de sortie (3A) et une seconde section de sortie / d'entrée (3B) à l'intérieur et à l'extérieur de laquelle s'écoule un fluide frigorigène mélangé non azéotrope, et des premières sections de tuyau (31A) et des secondes sections de tuyau (32A) qui sont reliées en série l'une à l'autre entre la première section de sortie / d'entrée et la seconde section de sortie / d'entrée et à travers lesquelles s'écoule le fluide frigorigène mélangé non azéotrope ; un dispositif de décompression ; et un second échangeur de chaleur (6). Le fluide frigorigène mélangé non azéotrope comprend un fluide frigorigène qui a la propriété de provoquer une réaction de dismutation et un fluide frigorigène qui n'a pas la propriété de provoquer une réaction de dismutation. La vanne à quatre voies commute entre un premier état dans lequel le fluide frigorigène mélangé non azéotrope s'écoule à travers le compresseur, le premier échangeur de chaleur, le dispositif de décompression et le second échangeur de chaleur dans cet ordre et un second état dans lequel le fluide frigorigène mélangé non azéotrope s'écoule à travers ces composants dans la direction opposée à celle du premier état. Lorsqu'il se trouve dans le premier état, le fluide frigorigène mélangé non azéotrope s'écoule à travers les premières sections de de sortie / d'entrée, les premières sections de tuyau, les secondes sections de tuyau, et la seconde section de sortie / d'entrée dans cet ordre à l'intérieur du premier échangeur de chaleur. Lorsqu'il se trouve dans le second état, le fluide frigorigène mélangé non azéotrope s'écoule à travers la seconde section de sortie / d'entrée, les secondes sections de tuyau, les premières sections de tuyau, et la première section de sortie / d'entrée dans cet ordre à l'intérieur du premier échangeur de chaleur. Le taux d'expansion de surface des premières surfaces circonférentielles internes dans les premières sections de tuyau est supérieur au taux d'expansion de surface des secondes surfaces circonférentielles internes dans les secondes sections de tuyau.
