FIELD: transport.
SUBSTANCE: invention relates to ship building. Proposed system comprises two sweet water circulation circuits. First circuit comprises circulation tank whereto sweet water is fed from power plant. Second circuit comprises ribbed coil built in said tank and sweet water cooler. Water fed into circulation tank from power plant is cooled by heat exchange with coil surface. Water cooled in cooler with the help of refrigerating plant circulates in said coil. Refrigerating plant represents closed coolant circuit and comprises evaporator accommodated in cooler, screw compressor, condenser and receiver. Higher reliability and longer life due to ruling out of sea water from cooling system.
EFFECT: reduced cooling system materials/output ratio.
