SUPERCONDUCTIVE CABLE COOLING SYSTEM HAVING INTEGRATION OF LIQUID NITROGEN CIRCULATION AND REFRIGERATOR

Abstract:

The present invention relates to a superconductive cable cooling system including: a refrigerator unit including a compressor and an after-cooler; a plurality of heat exchangers for performing heat exchange of a cooling fluid; an expansion valve for performing throttle expansion of the cooling fluid; an expander for adiabatically expanding the cooling fluid; a superconductive cable; and a plurality of branch points at which the cooling fluid is branched and joined, wherein the cooling fluid functions as both a refrigerant for the refrigerator unit and a coolant for the superconductive cable.
