An apparatus produces hydrate slurry, which is a mixture of aqueous solution and hydrate, by cooling aqueous solution containing a guest compound, which generates the hydrate at temperature higher than 0&#xb0; C., by using a cooling medium. The apparatus includes a first heat exchanger for supercooling the aqueous solution while holding the aqueous solution in a liquid state and in a second heat exchanger, which is provided on the downstream side of the first heat exchanger for cooling hydrate slurry.

Apparatus for producing hydrate slurry

A thermal storage apparatus for using a hydrate thermal storage medium including: (a) a storage tank for storing a cooling medium liquid; (b) a refrigerating machine, connected with the storage tank via a pipe for cooling the cooling medium liquid, the cooling medium liquid circulating between the storage tank and the refrigerating machine; and (c) a thermal storage body immersed in the cooling medium liquid, wherein the thermal storage medium comprises a hermetically sealed container containing an aqueous solution which generates at least one hydrate selected from the group consisting of a primary hydrate and a secondary hydrate, wherein the primary hydrate has a smaller hydration number and a small heat capacity than the secondary hydrate, and wherein the secondary hydrate has a larger hydration number and a larger heat capacity than the primary hydrate.

Thermal storage medium using a hydrate and apparatus thereof, and method for producing the thermal storage medium

A method and apparatus for making a hydrate slurry, which involves the preparation of an aqueous solution of a guest compound for forming a clathrate hydrate, cooling the aqueous solution, and contacting the aqueous solution with nuclear particles. A thermal storage method, a thermal storage apparatus, and a thermal storage medium using an aqueous solution of a clathrate hydrate, in a concentration which provides a congruent melting point or lower. A refrigerating apparatus and an air conditioner using the thermal storage apparatus and the thermal storage medium.

Air conditioning and thermal storage systems using clathrate hydrate slurry

A method for transporting cold latent-heat which comprises contacting a source of cold latent-heat with a liquid-liquid clathrate capable of crystallization when an onium salt having a C,H,group and an iso-C,H,group is included as a guest into basket-like inclusion clathrate lattices including water molecules.
