Title (EN) COMPRESSOR AND REFRIGERATION CYCLE DEVICE
(FR) COMPRESSEUR ET DISPOSITIF DE CYCLE DE RÉFRIGÉRATION
(JA) 圧縮機及び冷凍サイクル装置
Abstract:
(EN) The present invention is equipped with: a compression mechanism unit (35) that compresses a refrigerant and is provided within a shell (8) serving as a sealed container; a crankshaft (4) that imparts rotational force to the compression mechanism unit (35); a bearing (3a) that holds the crankshaft (4); and an oil pump (21) that supplies refrigerant oil to the bearing (3a). The displacement volume (Vst) [cc/rev] of the refrigerant in the compression mechanism unit (35) satisfies the relationship 20 ≤ Vst ≤ 35 [cc/rev], and an ester oil for which the kinetic viscosity (ν) [mm2/s] at 40°C satisfies the relationship 480/(6.5 - 0.13×Vst) < ν < 300 [mm2/s] and having a viscosity index of 80-200 is used as the refrigerant oil.
(FR) La présente invention comprend : une unité de mécanisme de compression (35) qui comprime un réfrigérant et est agencé dans une coque (8) faisant office de récipient scellé ; un vilebrequin (4) qui transmet une force de rotation à l'unité de mécanisme de compression (35) ; un palier (3a) qui supporte le vilebrequin (4) ; et une pompe à huile (21) qui fournit le réfrigérant au palier (3a). Le volume de déplacement (Vst) [cc/rev] du réfrigérant dans l'unité de mécanisme de compression (35) satisfait la relation 20 ≤ Vst ≤ 35 [cc/rev] et une huile d'ester pour laquelle la viscosité cinétique [mm2/s] à 40 °C satisfait la relation 480/(6,5 - 0,13 × Vst) < ν < 300 [mm2/s] et qui présente un indice de viscosité compris entre 80 et 200, est utilisée comme huile de réfrigérant.
(JA)  密閉容器となるシェル8内に設けられ、冷媒を圧縮する圧縮機構部35と、圧縮機機構部35に回転力を付与するクランクシャフト4と、クランクシャフト4を保持する軸受3aと、軸受3aに冷凍機油を供給するオイルポンプ21とを備え、圧縮機構部35における冷媒の押しのけ量Vst[cc/rev]が、20≦Vst≦35[cc/rev]を満たし、40[℃]における動粘度ν[mm/s]が、480/(6.5-0.13×Vst)<ν<300[mm/s]を満たし、かつ粘度指数80~200のエステル油を冷凍機油とする。
