To provide an effective and reliable system, cooling superconducting equipment.
A cooling fluid 5, at a temperature within the range of typically about -243.15 to -223.15°C, is delivered to a cryogenic cooler 7 inside a vacuum sleeve 8. The vacuum sleeve provides insulation to the cold end of the cryogenic cooler, and a heat exchanger 9 at this low-temperature end. The cooling fluid 5 is delivered through the heat exchanger 9 of the cryogenic cooler 7 and cooled. Then, it becomes a cooling fluid flow 10, that is cooled at the temperature within the range of generally about -253.15 to -243.15°C, and leaves the cryogenic cooler 7. The cooled cooling fluid flow 10 becomes the cooling fluid flow 19 at the temperature of typically about -272.15 to -269.15°C, that is a temperature higher than that of the cooling fluid 10, cooled through indirect heat exchange with a ballast liquid. Then, it is delivered to the superconducting equipment 20, where it provides cooling to the superconducting equipment 20 through either direct or indirect heat exchange.
