Description
パージ制御装置190の制御された動作により、圧力スイング吸着システム100により生成される製品ガスの酸素濃度の増大が可能となる。既存の装置では、圧力スイング吸着サイクルの供給ステップの間、固定の機械加工オリフィスのみが使用され、一つのシーブチャンバから別のシーブチャンバへの酸素のパージ流が制御される。
上昇酸素濃度モードに加えて、パージ制御装置190の制御された動作により、圧力スイング吸着システム100による電力消費が抑制される。電力保護モードで作動する圧力スイング吸着システムの実施例では、アクティブパージ制御装置の流速アルゴリズムを使用することにより、システムの電力消費が最小限に抑制される。圧力スイング吸着システムの電力保護モード用の流速アルゴリズムは、実施されるアルゴリズムから、アクティブパージ制御装置のタイミングを変化させ、これにより最大酸素濃度が得られる。
上昇酸素濃度モードおよび電力保護モードに加えて、本発明では、圧力スイング吸着システム100が騒音抑制モードで動作されるように、パージ制御装置190の動作を制御することが想定される。騒音抑制モードで動作される圧力スイング吸着システムの実施例では、アクティブパージ制御装置用の流速アルゴリズムを実施することにより、システムの騒音が最小化される。圧力スイング吸着システムの騒音抑制モードにおける流速アルゴリズムは、実施されるアルゴリズムから、アクティブパージ制御装置のタイミングを変化させ、最大酸素濃度または最小電力消費のいずれかが得られる。
本発明では、圧力支持システムの作動モードの選定は、手動または自動で行われることが想定される。作動モードを手動選定する場合、入力/出力装置180は、ロジック制御装置150と通信可能に提供される。ユーザは、作動モードを手動で選択し、入力/出力装置180を用いて、例えば上昇酸素モード、電力保護モード、騒音抑制モードが選定される。本発明では、入力/出力装置180は、この機能を有するいかなる適当な装置、例えばスイッチ、ノブ、ボタン、キーパッド、タッチスクリーンディスプレイ、および音声活性化または音声認識装置等であっても良いことが想定される。これにより、ユーザに、幅広い自由度が提供され、ユーザの現在の要望に応じて、PSAシステムを作動する際の最良の方法が選定される。
通常、圧力スイング吸着サイクルには、バランス段階が挿入される。このバランス段階では、圧力スイング吸着システムのシーブチャンバが均等化される。バランス段階は、一つのシーブチャンバの加圧状態に依存し、別のシーブチャンバを加圧する際に利用され、これにより圧縮機の側での要求が抑制される。シーブチャンバでのパージ段階が完了後、シーブチャンバの圧力は、激減する。後続の供給段階を効率的にするため、シーブチャンバは、再加圧される必要がある。2以上のシーブチャンバを備える圧力スイング吸着システムでは、パージおよび供給の段階は、同期化され、一つのシーブチャンバがパージ段階の場合、他方のものは、供給段階となる。従って、パージされるチャンバを用いて、供給されるチャンバの加圧が助長される。バランス段階は、供給段階とパージ段階の間に生じる。
