The developed clathrate hydrate has latent-heat over the temp. range of 5〜12℃, and a mixture of clathrate hydrate and aqueous solution (referred to as hydrate slurry) has grater cooling capacity compared to cold water. The utilization of the hydrate slurry in air-conditioning system is expected to reduce the pumping power consumption dramatically. Densities of the aqueous solution , the clathrate hydrate and the hydrate slurry were measured. The measured density of hydrate slurry showed a good agreement with a calculated value.
