Abstract

La présente invention concerne un climatiseur qui, lorsqu'un premier échangeur de chaleur, à savoir un échangeur de chaleur (12) du côté source de chaleur, joue le rôle d'un condenseur, est commandé de sorte que, alors qu'un fluide frigorigène circule à travers un premier tuyau de dérivation (4a) vers un tuyau du côté arrivée pour un accumulateur (15) via des dispositifs (14a et 14d) d'étranglement, ledit fluide frigorigène s'écoule également à travers un second tuyau de dérivation (4b) via l'un des dispositifs (14b) d'étranglement et est introduit dans un canal entre un compresseur (10) et l'accumulateur (15). Lorsque l'échangeur de chaleur (12) du côté source de chaleur joue le rôle d'un évaporateur, le climatiseur est commandé de sorte que le fluide frigorigène s'écoule à travers le second tuyau de dérivation (4b) via le dispositif (14b) d'étranglement susmentionné et est introduit dans le canal entre le compresseur (10) et l'accumulateur (15) et l'autre dispositif (14d) d'étranglement est soit complètement fermé, soit fermé de sorte que pratiquement aucun fluide frigorigène ne s'écoule à travers celui-ci.
