Description
主圧縮機は、駆動モータにより一定の回転数に保たれるので圧縮されるべきガスの一定の体積流量を吸い込む。前圧縮機を介して供給圧力が上昇させられると、圧縮機システム全体の体積流量が増大することになる。供給圧力が1bar(g)の場合、同一温度において体積流量は倍増し、2bar(g)では3倍になり、3bar(g)ではそれどころか4倍になった。
所望の体積流量を伴う圧縮機システムを実現するために、主圧縮機は、供給圧力が1bar(g)で同一温度の場合、前圧縮無しの圧縮機システムの場合のわずか1/2の大きさに寸法設定されるに過ぎない。それどころか供給圧力が2bar(g)の場合には、構成サイズが通常の構成サイズの約1/3に縮小し、同様に3bar(g)の場合も約1/4に縮小することになる。
前圧縮機と主圧縮機との間の最適に選択された圧縮比に基づき、全体効率は良好な中間冷却において、15%を上回って改善され得る。このことは、エネルギ消費量の大幅な減少につながり、延いては圧縮機システム運転における大幅なコスト節減につながることになる。
システム運転者により、より高い作動圧力が所望された場合、より高い作動圧力は、供給圧力の低下延いては体積流量の減少により形成され得る。主圧縮機は、より高い圧力を得るためにより高いトルクを必要とし、前圧縮機は、より低い供給圧力に基づき、駆動モータの供与可能なトルクと、前圧縮機及び主圧縮機の所要トルクとの間に再び均衡が生じるまで、その所要トルクを低下させることができる。
電動モータにより駆動される圧縮機システムの場合は本発明に基づき、種々様々なパラメータ、例えば消費電力及び電圧の監視、又は巻線温度の監視により、モータの負荷を最適に適合させることが可能である。
