Title
(EN) REFRIGERANT PIPE AND AIR-CONDITIONING DEVICE
(FR) TUYAU DE FLUIDE FRIGORIGÈNE ET DISPOSITIF DE CLIMATISATION
(JA) 冷媒配管、及び、空気調和装置
Abstract
(EN)
A refrigerant pipe which is connected to an elemental component (X) constituting a refrigerant circuit in a refrigeration device, and through which a refrigerant flows, wherein the refrigerant pipe includes a first portion (21) and a second portion (22), the first portion (21) is stainless steel, the second portion (22) is provided on an end of the first portion (21) and is connected to a connection-receiving surface (X2a) of the elemental component (X), and the second portion (22) comprises a material that differs from the first portion (21) and is the same as that of the connection-receiving surface (X2a).
(FR)
Tuyau de fluide frigorigène qui est relié à un composant élémentaire (X) constituant un circuit de fluide frigorigène dans un dispositif de réfrigération, et à travers lequel circule un fluide frigorigène. Ledit tuyau de fluide frigorigène comprend une première partie (21) et une seconde partie (22). La première partie (21) est en acier inoxydable, la seconde partie (22) est disposée sur une extrémité de la première partie (21) et est reliée à une surface de réception de raccordement (X2a) du composant élémentaire (X), et la seconde partie (22) comprend un matériau qui diffère de la première partie (21) et est identique à celui de la surface de réception de raccordement (X2a).
(JA)
冷凍装置の冷媒回路を構成する要素部品(X)に接続され、冷媒が流れる冷媒配管であって、冷媒配管が、第1の部分(21)と第2の部分(22)とを含んでおり、第1の部分(21)が、ステンレス製であり、第2の部分(22)が、第1の部分(21)の端部に設けられかつ要素部品(X)の被接続面(X2a)に接続され、さらに、第2の部分(22)が、第1の部分(21)とは異なる材料であって被接続面(X2a)と同一の材料からなる。
