未利用熱の有効利用を目的とするスラリー熱媒体の蓄熱量の評価

抄録

In this study, specific heat and heat of dilution of solution were measured to estimate effective latent heat of fusion of the solute in its aqueous solution. Erythritol solution and mannitol solution were used as a sample. In the measurement of heat of dilution, pure water was mixed into the solution, and temperature variations of the solution due to the dilution of the solution was measured. From the temperature variation, heat of dilution of the solution can be calculated. As a result, it was found that the influence of dilution of the aqueous solution on the effective latent heat of fusion of erythritol and mannitol was small.
