<P>PROBLEM TO BE SOLVED: To provide a liquid medium composition for heat exchange which exhibits a stable fluidity even at a temperature as low as -30°C or lower and does not cause precipitation of inorganic salts at a temperature around room temperature. <P>SOLUTION: The liquid medium composition for heat exchange comprises an aqueous solution containing an inorganic salt added at a concentration at which the freezing point is lowered to -10°C or below and the lowest freezing point is not reached and 0.01-5 wt.% of a surfactant. A liquid phase of the freezing point is further lowered by the collaborated action of the inorganic salt and the surfactant and an ice slurry in which a solid liquid equilibrium is reached at a freezing point corresponding to the concentration of the inorganic salt. <P>COPYRIGHT: (C)2007,JPO&INPIT |
