Abstract
(EN) The present invention addresses the problem of preventing the propagation of a disproportionation reaction of a refrigerant. Provided is a use of a composition containing one or more components selected from the group consisting of an ethylene-based fluoroolefin, 2,3,3,3-tetrafluoropropene (HFO-1234yf) and 1,3,3,3-tetrafluoropropene (HFO-1234ze) as a refrigerant in a compressor (21) which is configured such that the flow rate of a refrigerant flowing through an ejection tube (95) under a specific high-pressure condition becomes 1 m/s or more.
(FR) La présente invention aborde le problème consistant à éviter la propagation d'une réaction de disproportionation d'un fluide frigorigène. L'invention concerne une utilisation d'une composition contenant un ou plusieurs composants choisis dans le groupe constitué par une fluorooléfine à base d'éthylène, du 2,3,3,3-tétrafluoropropène (HFO-1234yf) et du 1,3,3,3-tétrafluoropropène (HFO-1234ze) en tant que fluide frigorigène dans un compresseur (21) qui est conçu de telle sorte que le débit d'un fluide frigorigène s'écoulant à travers un tube d'éjection (95) dans une condition de haute pression spécifique devient supérieur ou égal à 1 m/s.
