The viscosity of the adhesion and aggregation, reduction slurry that are adjusted between the solidification phase transition temperature of solution, ice pellets with additives such as alcoholic compounds changes
Kind mobile performance；Cohesion between ice pellets is improved, and ice pellets size is more uniform.
The ice slurry that microemulsion in the present invention is mutually deformed into has higher cold-storage ability, heat transfer property good；Ice slurry shape
At phase transformation degree of supercooling between 0.2~0.5 DEG C, phase transition temperature is between -1~-1.5 DEG C.
The preparation method of above-mentioned preparation ice slurry microemulsion, includes the following steps, mixing water and atoleine, then successively
Surfactant, alcoholic compound is added, concussion, which handles to obtain, prepares ice slurry microemulsion.
In above-mentioned technical proposal, concussion processing time is 3~5 minutes, and lotion is not in after the ice slurry prepared is melted
Lamination.
The invention also discloses above-mentioned preparation ice slurry microemulsions to prepare cold-storage ice slurry or in preparing cold-storage material
Using.
A kind of cold-storage method for regulating temperature, includes the following steps：
（1）Then mixing water and atoleine sequentially add surfactant, alcoholic compound, concussion, which handles to obtain, prepares ice slurry
Use microemulsion；
（2）Ice slurry microemulsion will be prepared to be fitted into container, crystallization obtains ice slurry, completes cold-storage；
（3）Ice slurry is melted, and cold, completion cold-storage temperature adjustment is released.
Ice slurry has good mobility and transmission performance, can store in ice storage tank and be flowed in pipeline.The phase of ice slurry
It is big to become latent heat, a large amount of colds are can release in heat transfer process；The presence of ice pellets in ice slurry, because of its large specific surface area, heat exchange efficiency
It is higher, cold can be quickly released, workload demand is met.In identical thermic load, compared with chilled water system, use
Ice slurry can reduce line size as refrigerating medium, reduce system initial cost, reduce flow, reduce the energy consumption of water pump conveying, comprehensive
Cost can reduce by 30%；And ice-making system is run at night, can make full use of power grid trough-electricity, has good economy.
Compared with traditional ice slurry preparation system, the characteristics of this patent be by increase in phase transformation system atoleine,
Surfactant forms microemulsion with cosurfactant, overcomes lotion and prepares the demulsifying phenomenon occurred in the process after ice slurry,
Microemulsion has good stability in ice making/ice-melt cyclic process, and reduces ice slurry and form degree of supercooling.
