Résumé

When ice slurry is employed for air conditioning, there is gap of 5–7 °C between the melting point of the ice and the cooling water temperature. However,TBAB hydrate slurry made from an aqueous TBAB solution can remove the gap because it has a more suitable melting point. Furthermore, the slurry is relatively a high latent heat of fusion and good fluidity. So, the slurry is the most promising material for air conditioning. However, it is expected that TBAB hydrate in the slurry strongly adheres to surface of a metal such as copper. However, to date, there have been no quantitative studies of the adhesion forces, so in the present work adhesion forces of TBAB hydrates to copper surface at 3 and 5 °C were measured varying TBAB solution concentrations. And the adhesion force and its surface temperature-dependency were investigated based on surface energies and observations of hydrates crystals.
