Abstract

L'invention porte sur un dispositif à cycle de réfrigération (100) qui est équipé d'un compresseur de commande de volume (101), d'un passage de commande de volume (111), d'une vanne à quatre voies (unité de commutation des trajets d'écoulement) (112), d'un passage (114) d'introduction de haute pression, d'un passage (116) d'introduction de basse pression, et d'un clapet de non retour (120). Lorsque la charge est faible, la vanne à quatre voies (112) est commandée de telle sorte que le passage de commande de volume (111) est connecté au passage d'introduction de la basse pression (116). Lorsque la charge est grande, la vanne à quatre voies (112) est commandée de telle sorte que le passage de commande du volume (111) est connecté au passage (114) d'introduction de la haute pression. Le passage d'introduction de la haute pression (114) est équipé du clapet de non retour (120), qui permet la circulation du réfrigérant d'un trajet d'écoulement (10a) à la vanne à quatre voies (112) et interdit la circulation dans le sens inverse.
