Abstract

Le système frigorifique (2) comporte un circuit de flux principal (3) comportant un évaporateur (4), un turbocompresseur (5), un condenseur (6) et un détendeur principal (7) reliés en série, et étant configuré pour transporter un flux de fluide frigorigène principal ; une conduite de flux de dérivation (8) ramifiée à partir du circuit de flux principal (3) et étant configurée pour dériver une partie du flux de fluide frigorigène principal dans la conduite de flux de dérivation (8) en tant que flux de fluide frigorigène de dérivation et pour transporter le flux de fluide frigorigène de dérivation à travers le turbocompresseur (5) afin de refroidir un moteur de compresseur et un agencement de palier du turbocompresseur (5), la conduite de flux de dérivation (8) comprenant un détendeur de dérivation (12) situé en amont du moteur de compresseur et de l'agencement de palier ; et un dispositif de commande (13) configuré pour commander les degrés d'ouverture du détendeur principal (7) et du détendeur de dérivation (12).
