いる。2. Description of the Related Art When an aqueous solution containing a guest compound (various salts such as tetra-n-butylammonium salt, tetra-iso-amyl ammonium salt, tetra-iso-butylphosphonium salt, tri-iso-amyl sulfonium salt) is cooled, a hydrate is formed. (Liquid clathrate hydrate) is produced. 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 transport medium for air conditioners and the like.

物スラリタンクへ戻される。Conventionally, the production of such a hydrate slurry and its use in a load-side air conditioner or the like have been performed as follows. That is, an aqueous solution containing, for example, tetra-n-butylammonium bromide (TBAB) is supplied to the hydrate slurry tank, and the slurry production operation (heat storage operation) is started. The aqueous solution in the hydrate slurry tank is sent to a slurry production heat exchanger (for example, an evaporator of a refrigerator) by a production pump and cooled by heat exchange to produce a hydrate slurry. This hydrate slurry is stored in a hydrate slurry tank. Further, during the load operation, the hydrate slurry in the hydrate slurry tank is sent to the load side heat exchanger by the load pump and the cold heat is used to form an aqueous solution, and the aqueous solution is returned to the hydrate slurry tank.

含む水和物スラリを用いることが望ましい。By the way, tetra-n-butylammonium bromide (TBAB) is composed of a first hydrate having a small hydration number and a low formation temperature and a second hydrate having a large hydration number and a high formation temperature in a low concentration region. It is known that it can be produced (only the first hydrate is produced in the high concentration region). Of the two hydrates, the second hydrate has a higher heat density and a larger amount of cold energy, and therefore, it is desirable to use a hydrate slurry containing the second hydrate for the air-conditioning load operation.

動力の変動を招いていた。[0005] However, if continuous cooling is performed in the slurry production heat exchanger according to the conventional method, the supercooling may be released after a large supercooling occurs, and in such a case, the hydrate is rapidly reduced. Is generated, the viscosity increases, the flow resistance increases, the pump power increases, and in the worst case, the heat exchanger may be blocked. Also, after the first hydrate is first formed during the slurry production operation, the first hydrate changes to the second hydrate even when the temperature falls below about 8.0 ° C. at which the second hydrate can be formed. Instead, it often subcooled to a lower temperature before changing to the second hydrate, causing fluctuations in pump power.
