Title (EN) REFRIGERATION DEVICE
(FR) DISPOSITIF DE RÉFRIGÉRATION
(JA) 冷凍装置
Abstract:
(EN) A refrigerant in a refrigerant circuit (11) includes a hydrofluorocarbon having the characteristic of causing disproportionation reactions. A compressor mechanism (40) has provided therein: a blade (51) integrally coupled to pistons (44, 44a, 44b, 77) and partitioning cylinder chambers (45, 45a, 45b, 81, and 82) into a low pressure chamber (L) and a high pressure chamber (H); and a pair of bushes (52) that are pivotably held in a pair of bush grooves (53) formed in cylinders (2, 42a, 42b, 75) and hold the blade (51) so as to be capable of moving forward and backwards.
(FR) L'invention concerne un circuit de fluide frigorigène (11) comportant un fluide frigorigène comprenant un hydrofluorocarbone ayant la particularité de provoquer des réactions de dismutation. Un mécanisme compresseur (40) comprend : une pale (51) accouplée d'un seul tenant à des pistons (44, 44a, 44b, 77) et séparant des chambres (45, 45a, 45b, 81 et 82) de cylindre en une chambre à basse pression (L) et une chambre à haute pression (H) ; et une paire de douilles (52) retenues pivotantes dans une paire de rainures (53) de douille formées dans des cylindres (2, 42a, 42b, 75) et destinées à retenir la pale (51) de façon qu'elle puisse se déplacer vers l'avant et vers l'arrière.
(JA) 冷媒回路(11)の冷媒は、不均化反応を起こす性質を有するフッ化炭化水素を含む冷媒である。圧縮機構(40)には、ピストン(44,44a,44b,77)と一体に連結され、シリンダ室(45,45a,45b,81,82)を低圧室(L)と高圧室(H)とに仕切るブレード(51)と、シリンダ(2,42a,42b,75)に形成される一対のブッシュ溝(53)に揺動可能に保持されるとともにブレード(51)を進退可能に保持する一対のブッシュ(52)とが設けられる。
