Title
(EN) REFRIGERANT COMPRESSOR AND EQUIPMENT USING SAME
(FR) COMPRESSEUR DE FLUIDE FRIGORIGÈNE ET ÉQUIPEMENT L'UTILISANT
(JA) 冷媒圧縮機及びこれを用いた機器
Abstract
(EN)
A refrigerant compressor comprises: a sealed container in which refrigeration oil is stored; an electric component that is housed in the sealed container and driven by electricity supplied externally; and a compression component that is housed in the sealed container, is deposited in the refrigeration oil, is driven by the electric component, and compresses refrigerant gas supplied externally. The refrigeration oil contains, in a dissolved state, an oil film shortage regulating agent for which the concentration is regulated so as not to precipitate out at least during operation.
(FR)
Un compresseur de fluide frigorigène comprend : un récipient étanche dans lequel de l'huile de réfrigération est stockée; un composant électrique qui est logé dans le récipient étanche et entraîné par l'électricité fournie à l'extérieur; et un composant de compression qui est logé dans le récipient scellé, est déposé dans l'huile de réfrigération, est entraîné par le composant électrique, et comprime le gaz frigorigène fourni à l'extérieur. L'huile de réfrigération contient, dans un état dissous, un agent de régulation de pénurie de film d'huile pour lequel la concentration est régulée de manière à ne pas précipiter au moins pendant le fonctionnement.
(JA)
冷媒圧縮機は、冷凍機油が貯留された密閉容器と、密閉容器に収容され、外部より供給される電力により駆動される電動要素と、密閉容器に収容されて冷凍機油に被着され、電動要素により駆動されて、外部から供給される冷媒ガスを圧縮する圧縮要素とを備える。冷凍機油に、少なくとも運転時に析出しない濃度に調整された油膜切調整剤が溶解状態で含まれている。
