Title (EN) REFRIGERATION DEVICE AND REFRIGERATION SYSTEM
(FR) DISPOSITIF DE RÉFRIGÉRATION ET SYSTÈME DE RÉFRIGÉRATION
(JA) 冷凍装置、冷凍システム
Abstract: front page image
(EN) This refrigeration device (3) is provided with: multiple compressors (31) each of which has an oil pod (315) storing a lubricant oil; a level sensor (318) which detects when the level of the lubricant oil in the oil pods (315) falls to a predetermined reference level (LS); a communication tube (43) which allows communication between the oil pods (315) of the compressors (31); and a controller (100) which, when the level sensor (318) detects, in one of the multiple compressors (31), that the level has fallen to the reference level (LS), operates the multiple compressors (31) at mutually different rotation speeds.
(FR) Ce dispositif de réfrigération (3) comprend : de multiples compresseurs (31) dont chacun a une capsule d'huile (315) stockant une huile lubrifiante; un capteur de niveau (318) qui détecte lorsque le niveau de l'huile lubrifiante dans les capsules d'huile (315) chute à un niveau de référence prédéterminé (LS); un tube de communication (43) qui permet la communication entre les capsules d'huile (315) des compresseurs (31); et un dispositif de commande (100) qui, lorsque le capteur de niveau (318) détecte, dans l'un des multiples compresseurs (31), que le niveau a chuté au niveau de référence (LS), actionne les multiples compresseurs (31) à des vitesses de rotation mutuellement différentes.
(JA) 冷凍装置(3)は、潤滑油を貯留するオイルポッド(315)をそれぞれ有する複数の圧縮機(31)と、前記オイルポッド(315)内における前記潤滑油の液面レベルが予め定めた基準レベル(Ls)まで低下したことを検出するレベルセンサ(318)と、複数の圧縮機(31)のオイルポッド(315)同士を連通する連通管(43)と、複数の圧縮機(31)のいずれか一つにおいて、レベルセンサ(318)で前記液面レベルが基準レベル(Ls)まで低下したことを検出した場合に、複数の圧縮機(31)の回転数を互いに異ならせて運転するコントローラ(100)と、を備える。
