Abstract:
1. A system for cooling to a low temperature at least one piece of equipment, the system comprising a circulation loop ( 4 ) for heat-transfer fluid on which loop are mounted a low-temperature heat exchanger ( 60 ) and at least an equipment exchanger ( 102 ) comprising a heat-exchange surface, the heat-exchange surface of the equipment exchanger ( 102 ) being split between at least a first and a second heat-exchange section ( 104 , 106 ), the first heat-exchange section ( 102 ) having a first flow rate (Q 1 ) of heat-transfer fluid passing through it, the second heat-exchange section ( 106 ) having a second flow rate (Q 2 ) of heat-transfer fluid passing through it, the first flow rate (Q 1 ) being greater than the second flow rate (Q 2 ); wherein the low-temperature heat exchanger (
