Abstract

La présente invention concerne un système à cycle de réfrigération destiné au refroidissement d'un milieu devant être refroidi. Ce système comprend un compresseur de réfrigérant (3) destiné à compresser le réfrigérant après avoir refroidi le milieu devant être refroidi, un condensateur (6) destiné à la condensation du réfrigérant qui vient d'avoir été compressé par le compresseur de réfrigérant (3), une turbine à gaz uniaxiale (27) directement branchée au compresseur de réfrigérant (3), un circuit de retour de flux (12) reliant la partie amont du condensateur (6) à l'orifice d'entrée du compresseur de réfrigérant (3) et un papillon des gaz (13) permettant de réguler le flux dans le circuit de retour de flux (12). Ainsi on peut non seulement réduire la puissance requise au démarrage du compresseur de réfrigérant, mais on peut également atteindre la stabilisation du démarrage du compresseur de réfrigérant en utilisant la turbine à gaz uniaxiale comme source d'entraînement.
