A vapor compression system (10) having a line (19) for flowing heat transfer fluid (34), a compressor (12) and a condenser (14) both connected with the line (19). The vapor compression system (10) also has an expansion device (18) connected with the line (19) for expanding the heat transfer fluid (34). The expansion device (18) has a housing (40) defining an orifice (44, 46, 62, 66, 74, 76) with at least two positions, wherein the orifice is effectively made larger in the first position than in the second position. The vapor compression system (10) also has an evaporator (16) connected with the line (19) for transferring heat from ambient surroundings to the heat transfer fluid (34).
L'invention concerne un système de compression de vapeur (10) doté d'un conduit (19) d'écoulement de fluide de transfert de chaleur (34), d'un compresseur (12) et d'un condenseur (14) tous deux connectés au conduit (19). Le système de compression de vapeur (10) comprend aussi un dispositif d'expansion (18) connecté au conduit (19) permettant l'expansion du fluide de transfert de chaleur (34). Ce dispositif d'expansion (18) possède un logement (40) définissant un orifice (44, 46, 62, 66, 74, 76) à au moins deux positions, cet orifice se présentant plus grand dans la première position que dans la seconde. Le système de compression de vapeur (10) comprend aussi un évaporateur (16) connecté au conduit (19) et destiné à transférer la chaleur environnante au fluide de transfert de chaleur (34).
