Abstract:
(EN) One main pipe (77) connected to a liquid line (60) and having an expansion valve (78), and multiple branch pipes (81a, 81b, 81c) branching off from the outflow end of the main pipe (77) to connect to compressors (13a, 13b, 13c) and each having a flow adjustment valve (82a, 82b, 82c) are provided in an injection circuit (81). A control unit (100) is provided which, during an injection operation, maintains at a prescribed fixed opening degree the flow adjustment valves (82a, 82b, 82c) corresponding to prescribed compressors (13a, 13b, 13c) of the multiple compressors (13a, 13b, 13c), and adjusts the opening degrees of the compression valve (78) and the remaining flow adjustment valves (82a, 82b, 82c).
(FR) Dans la présente invention, un tuyau principal (77) relié à une conduite de liquide (60) et ayant un détendeur (78), et de multiples tuyaux de dérivation (81a, 81b, 81c) se ramifiant à partir de l'extrémité de sortie du tuyau principal (77) pour se connecter à des compresseurs (13a, 13b, 13c) et ayant chacun une soupape de réglage de débit (82a, 82b, 82c) sont prévus dans un circuit d'injection (81). Une unité de commande (100) est configurée, de sorte, pendant une opération d'injection, qu'elle maintienne à un degré d'ouverture fixe prescrit les soupapes de réglage de débit (82a, 82b, 82c) correspondant à des compresseurs prescrits (13a, 13b, 13c) des multiples compresseurs (13a, 13b, 13c), et règle les degrés d'ouverture de la soupape de compression (78) et des soupapes de réglage d'écoulement restantes (82a, 82b, 82c).
(JA) インジェクション回路(81)には、液ライン(60)に接続するとともに膨張弁(78)を有する1つの主管(77)と、該主管(77)の流出端から分岐して複数の圧縮機(13a,13b,13c)にそれぞれ繋がるとともに、各々が流量調節弁(82a,82b,82c)を有する複数の分岐管(81a,81b,81c)とが設けられる。インジェクション動作において、複数の圧縮機(13a,13b,13c)のうち所定の圧縮機(13a,13b,13c)に対応する流量調節弁(82a,82b,82c)を所定の固定開度に維持するとともに、膨張弁(78)及び残りの流量調節弁(82a,82b,82c)の開度をそれぞれ調節する制御部(100)を備える。
