Abstract

See full text

Liquefier includes first compression section which is driven by a superconducting motor and which compresses a substance in a gaseous state. Cooling circuit includes: second compression section which is driven by the motor when first compression section is being driven by the motor and which compresses a refrigerant; first heat exchange section which cools the refrigerant by causing heat exchange between a substance in a tank and the compressed refrigerant; second expansion section which brings the refrigerant down to or below a critical temperature of a superconducting material by expanding the cooled refrigerant; and second heat exchange section which imparts cold heat of the refrigerant to the substance by causing heat exchange between the substance in the tank and the refrigerant after cooling a superconducting magnet, and supplies the refrigerant brought down to or below the critical temperature by second expansion section to the motor and cools the superconducting magnet.
