INTEGRATED COOLING SYSTEM OF LIQUID NITROGEN CIRCULATION AND REFRIGERATOR FOR HTS CABLE

摘要

The present invention relates to a superconductive cable cooling system which comprises: a refrigerator system made of a compressor and a cooler; a plurality of heat exchangers in which heat of a cooling fluid is exchanged; an expansion valve configured to perform throttle expansion in the cooling fluid; an expander configured to perform adiabatic expansion in the cooling fluid; a superconductive cable; and a plurality of branch points through which the cooling fluid is branched or gathered. The cooling fluid simultaneously functions as a coolant role of the refrigerator system and a coolant role of the superconductive cable.
