Abstract
In this study, the thermal characteristics of water including an adsorbent were analyzed by a differential scanning calorimeter, DSC, in the temperature range from -20 to 20°C, and the heat generation by adsorbing the water was measured by a calorific meter, in order to examine the effects of the adsorption characteristics of the adsorbent. As a result, it was found that the surface adsorption water in a micro pore of nanometer order did not freeze and the capillary water could freeze. The capillary water showed the lower melting point than the free water. The latent heat of the capillary water decreased with increasing the adsorption heat of adsorbent.
