Summary

A calculation method to define the latent heat of fusion of ice in aqueous solution in the situation of the variation in the ice packing factor being infinitesimal is proposed. The calculation of the latent heat considers the effects of dilution and freezing-point depression, and the latent heat was calculated for five actual solutions, ethanol, ethylene glycol, propylene glycol, NaCl and NaNO3 solutions. Additionally, experiments in which ice was added to the five solutions were conducted to compare with the results of the calculations. Differential scanning calorimetry analysis was performed and the measurements and calculated values compared with respect to the specific enthalpy of the ice/solution mixture. Finally, since the values obtained by the measurements and calculations are in good agreement, the calculating method proposed in this study has proven to be adequate.
