Abstract

L’invention concerne un système de réfrigération (2) qui comprend: un cycle de réfrigération mettant en oeuvre un compresseur (4), un condenseur (6), un récipient collecteur (10) un dispositif de détente (16), un évaporateur (18), et des circuits frigorifiques dans lesquels circule un frigorigène; une conduite de dérivation (20) comprenant une soupape de dérivation (22), la conduite de dérivation (20) raccordant la lame d'air du récipient collecteur (10) à la conduite d'aspiration du compresseur (4); et une unité de commande qui, pendant son fonctionnement, autorise une commutation entre un mode de fonctionnement normal du cycle de réfrigération et un mode de collecte du frigorigène dans lequel la soupape de dérivation (22) s'ouvre et réduit la pression de liquéfaction dans le condenseur (6), si bien que le frigorigène liquide restant dans le condenseur (6) s'évapore en direction du récipient collecteur (10).
