Description
即ち、前記圧縮機台数制御装置６によってローテーションによる台数制御が行われていて、図６、図７に示すように前記下位圧縮機グループＣ１'に運転指令が発せられると、切替盤９は選択圧縮機Ｃ1Aを運転するよう制御し、この運転によっても貯留タンク３に備えた圧力開閉器１０が設定圧力以下の場合には切替盤９は追加圧縮機Ｃ1Bを運転するよう制御し、貯留タンク３に備えた圧力開閉器１０が設定圧力以上となった場合には切替盤９は追加圧縮機Ｃ1Bを無負荷運転するよう制御し、一定時間経過後に切替盤９は追加圧縮機Ｃ1Bを停止するようにしている。 That is, when the number control of the compressor is controlled by the compressor number control device 6, and the operation command is issued to the lower compressor group C1 ′ as shown in FIGS. When the pressure switch 10 provided in the storage tank 3 is equal to or lower than the set pressure, the switching panel 9 controls to operate the additional compressor C1B. When the pressure switch 10 provided exceeds the set pressure, the switching panel 9 controls the additional compressor C1B to perform no-load operation, and the switching panel 9 stops the additional compressor C1B after a certain period of time. Tei Ru.
即ち、前記圧縮機台数制御装置６によってローテーションによる台数制御が行われていて、図８、図９に示すように前記下位圧縮機グループＣ１'に運転指令が発せられ、切替盤９が追加圧縮機Ｃ1Bを運転するよう指令した際において、追加圧縮機Ｃ1Bの重故障発生を切替盤９が検出すると、切替盤９は選択圧縮機Ｃ1Aを運転するように指令する。このように、選択圧縮機Ｃ1Aと追加圧縮機Ｃ1Bの一方が運転中に重故障が発生した場合には、切替盤９に接続された対象機を優先してバックアップさせる。圧縮機台数制御装置６は自動バックアップしないように切替盤９と協調制御を行う。尚、切替盤９に接続された対象機に自動対象機が無い場合には、従来の圧縮機台数制御装置６によるバックアップ制御を優先する。
That is, the number control of the compressor is controlled by the compressor number control device 6, and an operation command is issued to the lower compressor group C1 'as shown in FIGS. When the switching panel 9 detects that a major failure has occurred in the additional compressor C1B when commanded to operate C1B, the switching panel 9 commands the selected compressor C1A to operate. As described above, when a major failure occurs during operation of one of the selected compressor C1A and the additional compressor C1B, the target machine connected to the switching panel 9 is preferentially backed up. The compressor number control device 6 performs cooperative control with the switching board 9 so that automatic backup is not performed. In addition, when there is no automatic target machine in the target machine connected to the switching board 9, priority is given to the backup control by the conventional compressor number control apparatus 6. FIG.
