- 極低温冷却部と、
前記極低温冷却部と冷媒との熱交換により前記極低温冷却部を冷却するよう構成された複数の冷媒循環ループであって、各冷媒循環ループが、前記冷媒を循環させる循環ポンプと、前記冷媒を冷却する機械式冷凍機と、を備える複数の冷媒循環ループと、
前記冷媒を流通可能に前記複数の冷媒循環ループを相互連結する連結ラインと、を備え、
前記連結ラインは、非連結状態から連結状態に切替可能に構成され、前記非連結状態では各冷媒循環ループの循環ポンプが当該冷媒循環ループについて前記冷媒を循環させるように前記複数の冷媒循環ループを相互に切り離し、前記連結状態では少なくとも1つの冷媒循環ループの循環ポンプが他の少なくとも1つの冷媒循環ループについても前記冷媒を循環させるように前記複数の冷媒循環ループを連結し、
前記複数の冷媒循環ループの各々は、一方が前記循環ポンプの上流側に設けられ、他方が前記循環ポンプの下流側に設けられ、前記非連結状態では開放され前記連結状態では閉鎖される一組の逆流防止用開閉弁を備えることを特徴とする極低温システム。 - 前記連結ラインは、2つの冷媒循環ループをつなぐ連結流路と、前記連結流路に設けられ、前記非連結状態では閉鎖され前記連結状態では開放される連結用開閉弁を備えることを特徴とする請求項1に記載の極低温システム。
- 前記連結ラインは、前記極低温システムの常温部に配置されていることを特徴とする請求項1または2に記載の極低温システム。
- 前記一組の逆流防止用開閉弁は、前記極低温システムの常温部に配置されていることを特徴とする請求項1から3のいずれかに記載の極低温システム。
- 少なくとも1つの冷媒循環ループは、各々が前記機械式冷凍機を備え、前記循環ポンプが前記冷媒を循環させる複数の冷媒循環サブループを備え、
前記複数の冷媒循環サブループは、個別に前記循環ポンプから切り離し可能であることを特徴とする請求項1から4のいずれかに記載の極低温システム。 - 少なくとも1つの冷媒循環ループは、前記極低温システムの低温部に配置された低温部冷媒管を備え、
前記機械式冷凍機が機能しない場合に想定される前記極低温システムの常温部から前記機械式冷凍機の冷凍機ステージへの熱伝導による単位時間あたり熱量が、前記冷凍機ステージから前記低温部冷媒管を通じた前記極低温冷却部への熱伝導による単位時間あたり熱量の1/100〜1/1000であることを特徴とする請求項1から5のいずれかに記載の極低温システム。
