Abstract:
1. A cooling system comprising a first heat exchanger ( 3 ) for heating a cooling liquid and a second heat exchanger ( 5 ), which comprises an evaporator, for cooling the cooling liquid, a pump ( 1 ) for guiding the cooling liquid through pipes ( 2 , 4 , 6 ) and through the first and second heat exchangers ( 3 , 5 ), a drain ( 13 ) for discharge of cooling liquid from the system and a supply ( 12 ) for addition of fresh cooling liquid into the system, wherein the system is connected to a pellet reactor ( 7 ) having an inlet ( 9 ) and an outlet ( 10 ) for cooling liquid, the inlet ( 9 ) being connected to any of the pipes ( 2 , 4 , 6 ) of the system by a conduit ( 8 ) for withdrawing liquid from the system, the outlet ( 10 ) being connected to any of the pipes ( 2 , 4 , 6 ) of the system by a conduit ( 11 ) for feeding cooling liquid from the pellet reactor ( 7 ) back to the system, and the pellet reactor ( 7 ) comprising a graft material for grafting impurities from the cooling liquid thereon.
