Abstract

L'invention concerne un appareil frigorifique comportant un évaporateur destiné à évaporer un fluide frigorigène, un compresseur destiné à comprimer le fluide frigorigène, et un condenseur condensant le fluide frigorigène comprimé à l'état de vapeur. Pour éviter des bruits gênants d'injection et d'écoulement dans l'évaporateur, un séparateur de liquides est monté en aval du condenseur dans le sens d'écoulement du fluide frigorigène. Le séparateur de liquides produit une meilleure distribution du fluide frigorigène.
