Description of the Related Art When an aqueous solution containing a guest compound (various salts such as tetra n-butylammonium salt, tetraiso-amylammonium salt, tetraiso-butylphosphonium salt, triiso-amylsulfonium salt) is cooled, a hydrate is formed. Is generated. This hydrate can be formed at a temperature of 0 ° C. or higher, and has a large latent heat, and can store cold energy several times as much as that of cold water. Further, the hydrate becomes fine particles and floats in the aqueous solution to form a hydrate slurry having relatively high fluidity. For this reason, such a hydrate slurry has favorable characteristics as a cold storage material or a cold transfer medium for air conditioning equipment and the like.

ましい。[0003] The hydrate slurry as described above is sent to a heat storage tank or a load side device, for example, an indoor unit of an air conditioner, through a piping system by a pump or the like. In particular, hydrate slurry is manufactured and stored using midnight power or waste heat,
In a system that uses the cold heat for air conditioning of a building or the like, the hydrate slurry must be circulated through complicated and long pipes in the building, and it is desirable to reduce the power required for the transportation.

Hydrate particles produced by cooling have a particle size of 10 to 300 μm
A hydrate slurry containing such fine particle hydrate is a non-Newtonian fluid. For this reason, when the solid phase ratio of the hydrate slurry increases, the transport heat density increases, but at the same time, the viscosity increases, the pressure loss during piping transportation increases, and the pump power increases. It has been found that there is a problem that it is necessary to increase the size and the equipment cost increases.
