Abstract
The invention aims to provide phase change coolant which has large latent heat, small condensate depression, good heat conductivity and phase change temperature ranged from -20 DEG C to -25 DEG C and is specifically used for refrigeration equipment of low temperature refrigerators. The coolant is prepared by mixing and agitating sodium chloride aqueous solution which is taken as main materials and ammonium chloride, sodium carboxymethylcellulose and borax which are taken as auxiliary materials. The coolant is transparent or semi-transparent colloidal liquid at normal temperature and changes the phase at -20 DEG C to -25 DEG C to form white solid. The product has the advantages of low cost, simple process and non-toxicity and harmlessness and is substantially free from corrosion on metal equipment.
Description
Technical field
The present invention relates to air conditioner refrigerating cold-storage technical field, the phase change cold accumulating agent that particularly a kind of low-temp. refrigerator is special-purpose.
Technical background
The modern times huge at resource consumption, that the energy is in short supply day by day, use renewable energy source, make full use of existing resources, carry out low-carbon economy and be our current top priority.Phase change cold-storage is the important means that reduces electric load; Concrete grammar is in low power consumption period refrigeration, makes phase change material undergo phase transition cold-storage, lets the phase change material absorption refrigeration in the peak of power consumption period; To reduce the power consumption consumption of refrigeration system at crest segment; Reach peak load shifting, reduce grid loss, improve electric energy efficiency.
Present low-temperature phase-change material has water, sal glauberi, ammonium chloride, Repone K etc., and transformation temperature is mainly used in ice cold-storage unit, food transportation at-5～10 ℃, and right-20～-25 ℃ low-temp. refrigerator phase-change material for cold storage does not also have report at present.
Summary of the invention
The object of the present invention is to provide that a kind of latent heat is big, condensate depression is little, conduct heat, transformation temperature is at-20～-25 ℃, specialty is used for the phase change cold accumulating agent of the refrigeration equipment of low-temp. refrigerator.
Cold storage agent of the present invention is main material with sodium chloride aqueous solution, and ammonium chloride, Xylo-Mucine, borax etc. are auxiliary material, processes through mixing to stir.
Cold storage agent of the present invention is transparent or semitransparent gel liquid at normal temperatures, undergoes phase transition at-20～-25 ℃, becomes white solid.Its moity is following according to mass percent:
Sodium-chlor 15～20%
Deionized water 71～76%
Ammonium chloride 3%
Sodium laurylsulfonate 1%
Borax 2%
Xylo-Mucine 3%
Said cold storage agent can prepare through following steps:
1, the solid matter weighing in the aforementioned formula is subsequent use, deionized water is with clean container, agitator
2, solid ingredient is added in the deionized water one by one, open electric mixer, under 250rpm, stir 30min, make the batching uniform dissolution and be scattered in the water.
3, the material after the stirring, after leaving standstill 12 hours, restir 15min.
Product of the present invention has simultaneously that cost is low, technology is simple, nontoxic, hardware do not had basically advantages such as corrosion.
Embodiment
Below in conjunction with embodiment the present invention is explained further details.
The component concentration of each embodiment of table 1 (mass percent)
The prescription of each embodiment in the table 1 is prepared into the low-temp. refrigerator phase change cold accumulating agent according to the following step:
1, the solid matter weighing in will filling a prescription is subsequent use, and deionized water is with clean container, agitator;
2, solid ingredient is added in the deionized water one by one, open electric mixer, under 250rpm, stir 30min, make the batching uniform dissolution and be scattered in the water;
3, the material after the stirring, after leaving standstill 12 hours, restir 15min.
After each embodiment prepared completion, its performance parameter test result saw table 2
Each embodiment performance perameter of table 2
