Abstract

Le circuit de climatisation (3) pour refroidir l’habitacle (4) d’un véhicule automobile (1) comprend un fluide frigorigène et un dispositif de compression (5) comportant un éjecteur (11). Le système de climatisation comprend en outre des moyens de transfert de chaleur (10) configurés pour chauffer une première fraction (m1) du fluide frigorigène à partir d’une source chaude (SC) du véhicule, l’éjecteur étant configuré pour comprimer une deuxième fraction (m2) du fluide frigorigène à partir de la première fraction du fluide réchauffé. Référence : figure 1The air conditioning circuit (3) for cooling the passenger compartment (4) of a motor vehicle (1) comprises a refrigerant fluid and a compression device (5) comprising an ejector (11). The air conditioning system further comprises heat transfer means (10) configured to heat a first fraction (m1) of the refrigerant from a hot source (SC) of the vehicle, the ejector being configured to compress a second fraction (m2) of the refrigerant from the first fraction of the reheated fluid.
