ABSTRACT:
A cooling system comprising an evaporation cooling device for evaporating an aqueous solution, a water content providing device for allowing vapor evaporated from impurities-containing water to be absorbed into the aqueous solution, and a circulating device for circulating the aqueous solution between the water content providing device and the evaporation cooling device; and a cooling method characterized by comprising the steps of taking in impurities-containing water, cooling a high-temperature body by evaporating water content in an aqueous solution having a boiling point higher than that of the impurities-containing water, allowing vapor evaporated from the impurities containing water to be absorbed into the aqueous solution concentrated by the cooling step, feeding the aqueous solution diluted in the absorbing step to the cooling step, and discharging the impurities-containing water concentrated in the absorbing step. The aqueous solution circulates between the water content providing device and the aqueous solution desalination device, and no salts move between the aqueous solution and the impurities-containing water, thereby providing a cooling system free from scales.
