Summary:To provide a rotating machine cooling system having an excellent cooling performance while preventing occurrence of problems when the refrigerant leaks, and a cooling system for superconducting devices.SOLUTION: A rotating machine cooling system has a rotating part 4a including a superconducting circuit. The superconducting rotor 4 includes: a first tank capable of storing liquid nitrogen; and a nitrogen gas supply path 18 for supplying a nitrogen gas generated from liquid nitrogen to the superconducting circuit. The nitrogen gas generated from the liquid nitrogen stored in the first tank is supplied to the superconducting circuit of the rotating part 4a via the nitrogen gas supply path to cool the superconducting circuit. Thus, the nitrogen gas in a gaseous state is supplied as the refrigerant supplied to the rotating part.SELECTED DRAWING: Figure 2 【課題】冷媒が漏洩した際の不具合発生を防止しつつ、優れた冷却性能を有する回転機械の冷却システム、及び、超伝導デバイスの冷却システムを提供する。【解決手段】超伝導回路を含む回転部4aを有する回転機械の冷却システムであって、超電導ロータ4は、液体窒素を貯留可能な第1タンクと、液体窒素から生成された窒素ガスを超伝導回路に供給するための窒素ガス供給路18を備える。第1タンクに貯留される液体窒素から生成された窒素ガスは、窒素ガス供給路を介して、回転部4aの超伝導回路に供給されることにより、超伝導回路が冷却される。このように回転部に供給される冷媒として、気体状態にある窒素ガスが供給される。【選択図】図2
