In the dynamic ice storage system, ice slurry is used for air conditioning. However, there is a gap between melting point of ice and cooling water temperature, and the gap is 5～12°C. So, to settle the gap TBAB hydrate slurry which has good fluidity and larger latent heat of fusion has been noticed because its melting point can be adjusted to suitable temperatures for air conditioning by varying concentrations of TBAB solution. So, the melting point existing between 5 and 12°C can be realized. However, it can be expected that a strong adhesion force of TBAB hydrate to a cooling surface occurs during formation of TBAB hydrate slurry or its transport through a pipe. In this paper, adhesion forces of TBAB hydrate to the cooling copper surface at a fixed temperature were measured varying concentrations of TBAB solution, after which the measured values were quantitatively investigated by estimating mass of free water in the TBAB hydrate which varies according to concentration of TBAB solution.
