Abstract
The present invention relates to a cold storage agent which can be used in a refrigerator, an ice chest, a refrigerated cabinet, etc. The cold storage agent comprises a water solution containing ammonium chloride and metal chloride, wherein the weight percentage content of the ammonium chloride is from 8 to 30%; the weight percentage content of the metal chloride is from 0.1 to 19%. The latent heat of phase change is fully used by the present invention. The cold storage agent has suitable phase change temperature, large latent heat of phase change, and a narrow solidification and melting temperature range. The solidification temperature of the cold storage agent is between-30 DEG C and-5 DEG C, and the latent heat of phase change is greater than 300 KJ/kg. An ice separation phenomenon basically does not exist.
Description
Technical field
The present invention relates to cold storage agent, specifically, relate to a kind of cold storage agent that can be used in refrigerator, refrigerator, refrigerator and other regenerator.
Background technology
For making freezer compressor after shutdown or power failure, refrigerator can provide cold in a long time, makes to keep low temperature in the refrigerator, and some refrigerator manufacturing companies have adopted super ice bag cold-storage technology; On the other hand, for the vaporizer heat transfer temperature difference, reduce refrigerator current consumption, improve efficiency of energy utilization, refrigerator adopts uninterrupted formula vaporizer, and a large amount of relevant patent and bibliographical informations are also arranged; In addition, the low temperature of preventive medical transportation has for convenience also been adopted the cold-storage technology in its transport refrigeration equipment.Therefore, the cold-storage technology has become the technology of a kind of extensive utilization in refrigerating field.
Present employed cold storage agent, because it is abundant inadequately to cold storage agent research, or fusing point is improper, as certain patent refrigerator cold storage agent is salts solution, and transformation temperature is-12 ℃, is not suitable for two stars and three-star refrigerator cold-storage, this mainly is because the three-star refrigerator refrigeration chamber is interior below-18 ℃ after will guaranteeing compressor shutdown, cold storage agent must have certain heat transfer temperature difference, and the cold storage agent transformation temperature usually will be below-25 ℃, and this salts solution obviously is undesirable; Or have ice-precipiting phenomenon, the latent heat of phase change of cold storage agent can not effectively be absorbed near the fusing point of design and discharge, thereby the target cold insulation cold-storage effect when not reaching the regenerator design lose the meaning of utilizing the latent heat of phase change cold-storage.
Summary of the invention
The object of the present invention is to provide a kind of cold storage agent, can overcome the shortcoming of above-mentioned prior art, realize different transformation temperatures, make it can be respectively applied for freezer compartment of refrigerator and refrigerating chamber cold-storage by its formula rate of reasonable adjusting; By utilizing the rational transformation temperature of cold storage agent, reduce the vaporizer heat transfer temperature difference, improve efficiency of energy utilization, thereby reduce refrigerator current consumption.
The objective of the invention is to realize by following technical scheme, construct a kind of cold storage agent, form by ammonium chloride, metal chloride and water, wherein, the weight percent of ammonium chloride is 6～30%, the weight percent of metal chloride is 0.1～3.5%, and all the other are water, and described metal chloride is sodium-chlor or Repone K or calcium chloride.
In described cold storage agent of the present invention, described metal chloride is sodium-chlor or Repone K or calcium chloride.
Implement cold storage agent provided by the invention, made full use of latent heat of phase change, have suitable transformation temperature and bigger latent heat of phase change, and have narrower solidifying and the temperature of fusion scope, its temperature of solidification is between-30 ℃～-5 ℃, and there is not ice-precipiting phenomenon in latent heat of phase change substantially greater than 300KJ/kg.
Embodiment
Below in conjunction with embodiment, the characteristics of cold storage agent of the present invention are described further:
This cold storage agent is guidance with thermal conduction study, solution theory and thermodynamic (al) Phase Equilibrium theory, obtains by a large amount of test, and it is the aqueous solution based on ammonium chloride, sodium-chlor.By changing the composition proportioning of ammonium chloride, sodium-chlor or potassium chloride solution, can obtain being fit to respectively that cold compartment of refrigerator and refrigeration chamber regenerator use has the narrower cold storage agent that solidifies with the temperature of fusion scope.Proportion of composing according to prescription, the weight percent content of ammonium chloride is closely pressed 6～30%, the weight percent content of sodium-chlor is closely poured container (as beaker) into by 0.1～3.5Wt% (adding the cold-storage performance that sequencing does not influence cold storage agent), the water yield (tap water, distilled water, ion exchanged water etc.) that adds formula concentration required 66.5～89.5% stirs until dissolving fully and forms uniform solution.
Embodiment: the weight percent 8% of ammonium chloride, weight sodium chloride degree are 15%.All the other are water.Pei Zhi cold-storage liquid like this, transformation temperature is-24.45 ℃.
Embodiment: the weight percent 12% of ammonium chloride, weight sodium chloride degree are 0.3%.All the other are water.Pei Zhi cold-storage liquid like this, transformation temperature is-17 ℃.
Embodiment: the weight percent 2% of ammonium chloride, Repone K weight percent content are 19%.All the other are water.Pei Zhi cold-storage liquid like this, transformation temperature is-14.1 ℃.
According to cold storage agent of the present invention, good reliability, manufacture craft is simple, has saved the energy, and cost is low.
