Abstract
(EN) The present invention suppresses the propagation of a coolant disproportionation reaction. The present invention pertains to the use of a composition containing one or more types of compound 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 coolant in a compressor (21) in which the flow rate of the coolant flowing through the periphery of areas (86a, 91a, 93a) which produce ignition energy inside the compressor (21) under prescribed high-pressure conditions is 1 m/s or higher.
(FR) La présente invention élimine la propagation d'une réaction de disproportionation de fluide de refroidissement. La présente invention concerne l'utilisation d'une composition contenant un ou plusieurs types de composés 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 de refroidissement dans un compresseur (21), dans laquelle le débit du fluide de refroidissement s'écoulant à travers la périphérie de zones (86a, 91a, 93a) qui produit de l'énergie d'allumage à l'intérieur du compresseur (21) dans des conditions de haute pression prescrites est supérieur ou égal à 1 m/s.
(JA) 冷媒の不均化反応の伝播を抑制する。エチレン系のフルオロオレフィン、2,3,3,3-テトラフルオロプロペン(HFO-1234yf)、および、1,3,3,3-テトラフルオロプロペン(HFO-1234ze)からなる群より選択される1種または2種以上を含む組成物の、所定の高圧条件下において圧縮機(21)内部の着火エネルギ発生箇所(86a、91a、93a)の周囲を流れる冷媒の流速が1m/s以上となる圧縮機(21)における冷媒としての使用。
