LIQUEFACTION SYSTEM AND POWER GENERATION SYSTEM
First Claim
1. A liquefaction system comprising:
- a storage section which stores a substance, whose boiling point is equal to or lower than room temperature, in a liquid state;
a superconducting motor which includes a superconducting magnet constituted by a prescribed superconducting material;
a liquefier which includes a first compression section that is driven by the superconducting motor and that compresses the substance in a gaseous states and a first expansion section that changes the substance from a gaseous state to a liquid state by expanding the substance compressed by the first compression section, and which generates the substance in a liquid state to be stored in the storage section; and
a cooling circuit which includes a second compression section that is driven by the superconducting motor when the first compression section is being driven by the superconducting motor and that compresses a refrigerant, a first heat exchange section that cools the refrigerant by causing a heat exchange between the substance stored in the storage section and the refrigerant compressed by the second compression section, a second expansion section that brings the refrigerant down to or below a critical temperature of the superconducting material by expanding the refrigerant cooled by the first heat exchange section, and a second heat exchange section that imparts cold heat of the refrigerant to the substance by causing a heat exchange between the substance stored in the storage section and the refrigerant after cooling the superconducting magnet, and which supplies the refrigerant brought down to or below the critical temperature by the second expansion section to the superconducting motor and cools the superconducting magnet down to or below the critical temperature.

Abstract
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.
