Abstract

PROBLEM TO BE SOLVED: To provide an antifrosting method for refrigerators, freezing storage chambers, freezing windows, refrigerator trucks and refrigerator ships. SOLUTION: Frosting is prevented in such a manner that the easy-to-frost surfaces of refrigerating equipment are previously coated with a paste liquid obtained by mixing castor oil, a fluoroplastic, and a silicone resin and then, with a solution obtained by thickening an aqueous solution of calcium chloride at a concentration of 10-40% with a sericin protein and, at the same time, a porous container containing an alcohol solution of an alcohol titanate chelate compound is placed in a cooling chamber to increase the partial pressure of the alcohol. When the inner surfaces of a storage chamber are coated with the mixed liquid and, in addition, with the calcium chloride sericin protein solution to form a film, frosting is prevented by absorption of the water content in the air to effect snow melting, and thus, the electric efficiency is increased by 8% and the generation of a frost nest in which bacteria grow can be inhibited. Use of the coated film in roads and roofs can prevent snow damage and eliminate the trouble of removing snow.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION The present invention was developed as a defrosting agent. When an oily defrosting agent has excessive moisture in the air, the surface of the oily defrosting agent becomes fuzzy in the freezer compartment. Frost formation occurs. Therefore, if salts that absorb moisture in the air and do not freeze are applied as an absorbent to this surface, frosting will be controlled for a certain period of time, and when the absorbed water exceeds a certain amount, it will be easy to freeze. When spraying,
Even if the moisture in the air comes in contact, if the moisture in the air continues to be absorbed and the adsorbent is further sprayed before saturation, the frosting properties are further suppressed and the defrosting effect is maintained for a long time. Therefore, the frost formed in the opening and closing of the freezing compartment and its opening / closing door in the freezer and large freezer disappears due to the spray of the absorbent, and is sprayed at any time if the frost is sprayed and defrosted. Keep state. Next, this calcium chloride selasin protein solution is added to sand, illuminite, and lime and dispersed and applied to roads and entrance doors of houses, etc. One of the reasons that the icing on the road is eliminated is that when the thick layer is formed, it becomes easy to slip when the ice is formed, which makes it difficult to drive the car. Then, when the snow that has accumulated snow comes into contact with the cured product of the liquid, the snow melts, and the snow automatically disappears. If snow accumulates, sprinkling the liquid with a sprinkler will result in no snow accumulation and will automatically flow as a liquid and be removed. And there is an advantage that concrete cracks can be prevented if there is a serassin protein. When this calcium chloride selasin protein mixture is frozen, it becomes a plate and becomes 5 to 1%.
When a thick plate of 00 mm is made and attached to the road, there is no snow even if there is one month of snowfall. The hardened product of the present liquid frozen on the outer surface of the touyu has no icing. An undercastor oil mixture is applied to the roof, and the top surface is coated as a topcoat with calcium chloride selasin protein solution mixed with solid calcium chloride. The effect is used for a wide range of uses, for example, for snow melting of trains.

2. Description of the Related Art A frozen stocker for storing ice cream and ice confections is quenched by moisture in the air in the summer, and when it comes into contact with the inner wall of the stocker, a frosting phenomenon occurs. However, there is generally no measure to prevent this. Therefore, as a patent application for Kairen, a paste made by using the antifreeze effect of castor oil, adding sebacic acid to this, adjusting the viscosity, and adding a fluorinated resin or a silicone resin was used as a defrosting agent. When the humidity in the air exceeds 70%, there is a drawback that frost formation occurs in a frozen stocker coated with this paste in 3 to 7 days. Therefore, a salt in which calcium chloride selasin protein was dissolved was used as a salt that immediately absorbs moisture in the air and does not freeze until reaching a certain concentration in combination with this defrosting agent.

When calcium chloride is dissolved to form a 40% liquid, icing does not occur until -40 ° C, but the thin film coated on the surface of the stocker has high fluidity and absorbs moisture in the air. Even in a day, frosting occurs.
Therefore, it was necessary to increase the viscosity of calcium chloride and apply a thick coating to the inner wall of the stocker. However, if fluorinated resin or silicone resin was added, frosting would occur in about three days, so it was necessary to consider this measure. Was.

Means for Solving the Problems The calcium chloride 3
A water solution is prepared by dispersing calcium chloride powder in a 0-40% solution so that excess water in the air can be adsorbed. Another is to increase the viscosity by dissolving the protein serassin in a 30% aqueous solution of calcium chloride. In general, in a water solution of 30% or more of calcium chloride, there is a disadvantage that many of the thickeners are salted out and have no solubility. Therefore, even in a solution of calcium chloride of 30% or more, there is a thickening and dissolution. It was necessary to add a thickener to create the condition. When dissolving seracin protein in a 30% aqueous solution of calcium chloride,
When the calcium chloride concentration increases during processing and reaches 40%, crystallization takes place, so it is necessary to consider a countermeasure.

[Function] When a fluorinated resin and a silicone resin are added to castor oil and stirred with a stirrer to make a paste, the paste does not freeze at -40 ° C, so that it always maintains fluidity and is made of water-repellent fluorinated resin or silicone resin. When the moisture in the air comes in contact with the freezer stocker, the inner room is always quenched at -20 ° C or higher.
For about 3 days, the moisture in the air is less likely to condense and frost, but when the moisture in the air keeps more than 70% humidity like in summer, the frost is gradually increased after 3 days Begin.
Therefore, when the powder of calcium chloride is dispersed on the surface of the stocker to which the oil paint is applied, the water repellent action of the oil does not have the power to immediately absorb the moisture in the air. % Water solution is sprayed little and the frosting is partially formed. This tends to occur as the sprayed calcium chloride film becomes thinner. Therefore, in order to increase the thickness of the calcium chloride liquid film, it is necessary to impart a viscosity. For this reason, utilizing the feature that seracin protein dissolves in a high concentration calcium chloride solution as a thickener, the calcium chloride solution becomes highly viscous when it is dissolved while heating, and it seems to absorb water in the air continuously. become. In general, calcium chloride absorbs water in the anhydrous salt when the moisture in the air is relatively relaxed, and the moisture in the air is 5% or less in one hour. It is necessary to absorb water. For this purpose, it is necessary to use a calcium chloride solution in which 30 to 40% of serassin protein is dissolved, and it is necessary to use a paste obtained by mixing anhydrous calcium chloride powder with this calcium chloride solution. There is. However, in the latter case, when the anhydrous calcium chloride powder is mixed, the specific heat increases, so that it is necessary to limit the amount of the powder added to prevent the frosting completely as in the former case. As the other solvent having the absorbing action, a solvent in which a surfactant is mixed with glycols is used. In this case, there is a problem of some toxicity, but a combination of glycol and a surfactant in a solution of calcium chloride is also used, but in the case of glycols, a high concentration of calcium chloride is hardly soluble. When exposed to air, the water content in the air is gradually absorbed by the glycol, and the solubility of calcium chloride increases in proportion thereto, so that the absorption action is maintained. The polyglycol to which this glycol ethylene oxide is added has high viscosity and is convenient, but as the degree of polycrystallization increases, the crystal proceeds and the frosting property increases.
Mixing castor oil or sebacic acid mixed oil with fluorocarbon resin and silicon resin on the base material makes the paste liquid a highly viscous oil liquid, but this oil liquid hardens when cooled in a freezer stocker, and the humidity is low. When it exceeds 70%, thin frost is formed from about 3 days, and frost is gradually generated at the tip of the frost crystal. Therefore, if the surface of this oil solution is coated with a water absorbent solution in advance, even if the humidity exceeds 80%,
No frosting occurs during the day. In a freezer room of a general household freezer, a room temperature of about -25 ° C. is maintained, but there is no freezing and no frosting even after one month has passed in this room. Fishing boats, especially tuna freezers, do not prevent frosting because they are quick-frozen. However, the calcium chloride selasin solution of the present invention combined with castor oil solution as a topcoat and undercoat has almost no frosting properties in 10 days. There is no, but when spraying or applying calcium chloride containing this serassin protein even if there is frosting, since the frosting will disappear, when spraying or applying calcium chloride mixed solution when frosting occurs Does not cause frost damage. The calcium chloride mixture is harmless, so there is no hygiene problem. However, when this is directly sprayed on tuna fish, it has little frosting properties, but its taste is bitter, so it needs to be washed with water. The solvent containing Glycol surfactant does not freeze even at -30 ° C,
Although it is more toxic than calcium chloride serassin protein solution, washing with water is not only less toxic, but also undercoat castor oil,
It has a feature that it easily adheres to a fluorinated resin or silicon resin liquid film. As described above, the defrosting agent of the present invention is prepared by applying a mixture of castor oil, a fluororesin, and a silicone resin as a top coat with a calcium chloride selasin protein solution or a glycolic surfactant mixture. To prevent sex.
In addition, the addition of seracin protein modifies the water solubility of calcium chloride and increases the compressive strength during curing to form a thick coating film. Helps prevent road icing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the drawings, the present invention will be described in detail below with reference to embodiments.

FIG. 1 is a side view of an enlarged partially frozen aluminum plate or frozen plastics plate, in which a mixed castor oil film (2) is applied to the upper surface of a frozen plate composed of a frozen aluminum plate or frozen plastics plate (1); When cooling with the freezing spiral tube (5), the surface of the freezing plate (1) comes into contact with the moisture in the air and condenses the moisture in advance when the freezing plate (1) is cooled. Two hours after the frosting (4) is performed, frosting is performed to a thickness of about 1 mm.

FIG. 2 shows a side view of a frozen plate (1) showing frosting (4), and when mixed castor oil is applied to this frozen plate (1) to form an oily film (2) even at −30 ° C. The oily film does not freeze and forms a hard film, but when there is moisture in the air and the humidity rises to 80% or more, the surface of the oil film (2) contacts the surface of the oil film (2) when the moisture in the air comes into contact with the surface. Needlelike frost (4) occurs after 3 days.

FIG. 3 is a side view showing a surface of a frozen plate (1) which is multiply frosted. When the frozen plate (1) is cooled by the frozen spiral tube (5), one week later, the upper surface of the oily film (2) on the upper surface of the frozen plate (1) is placed on the frost layer (4) of water. Furthermore, it becomes thick gradually by frosting.

FIG. 4 shows a side view of a frozen plate (1) coated with calcium chloride water and a castor oil mixture, and the surface of the cooled plate (1) cooled by the frozen spiral tube (5) is mixed with castor oil. When the film (2) is applied and the surface is further coated with a calcium chloride solution (3) to form a film, the calcium chloride liquid film (3) absorbs moisture in the air and the calcium chloride liquid film (3) gradually becomes fluid, but the frosting property does not occur even after one week, but when the absorbed water becomes saturated, freezing of water occurs.

FIG. 5 is a side view of a freezing plate in which a calcium chloride solution is further sprayed on a top coating surface of calcium chloride water, and when it reaches a saturation level by absorbing moisture in the air, it becomes fluid, but it is sprayed (6). When spraying or applying concentrated water of calcium chloride solution to the surface of the calcium chloride solution coating (3),
If the fluidity of the calcium chloride solution is stopped and the moisture in the air continues to be absorbed until the water is saturated, there is no frosting property. Wiping with a piece and spraying a fresh concentrated calcium chloride solution will not cause frost for a certain period of time.

FIG. 6 is a side view of a frozen plate sprayed with an overcoat of calcium chloride water, and it takes one week to form a coating (4) by applying a concentrated solution of calcium chloride to a high viscosity so as not to become fluid. However, there is no frosting and there is no frosting for 2 weeks. The high viscosity becomes more than 10 ³ poise, since the viscosity as the cooling temperature decreases increases, the viscosity becomes extremely not absorb moisture in the air, since the manner perform Shimogi surface of the coating 1
0 ³ Good that poise is the mean viscosity. Further, when the calcium chloride is kept in an anhydrous state, the specific heat becomes high and the freezing is performed quickly, so that the moisture in the air cannot be absorbed. Therefore, the concentration of the calcium chloride water is preferably 30 to 40%. In the case of the glycol solution containing calcium chloride, the viscosity is further increased and the syrup becomes syrupy, but no frosting occurs. Glycol to which a surfactant has been added is also used as a defrosting agent because it does not freeze at -40 ° C. However, in the case of keeping food cool, highly toxic substances cannot be used. Liquid ones have less toxicity, and calcium chloride water added with glycols is also used as a defrosting agent.
A dispersion in which calcium chloride powder is dispersed in calcium chloride water can be used, but the frosting property is such that solids are promptly obtained.
In addition, a mixture of a glycol and a surfactant easily adheres to a castor oil film and has spreadability, so that it is convenient to use a harmless surfactant.

FIG. 7 shows an oblique front view of the frozen stocker box,
A castor oil film (2a) (2'a) is applied in advance to the surface of the inner wall (A) (B) of the stocker box (1a), and a calcium chloride solution (3a) (3'a) is applied to the surface. However, there is no frosting which occasionally sprays this liquid onto the surface with a spray (6a). An example of the composition of this defrosting agent is as follows.

[Example 1] Calcium chloride 30% Serasin protein 2% Water 68%

[Example 2] Calcium chloride 15% Ethylene glycol or glycerin 70% Surfactant 15%

[Example 3] Ethylene glycol or glycerin 90% Surfactant 10%

[Example 4] Proplenglycol or glycerin 80% Surfactant 10% Calcium chloride 10%

[Example 5] Propylene glycol 70% Water 20% -30% Surfactant 3% -10%

[Example 6] Liquid parapine 2% Surfactant 3% Ethylene glycol 95%

[Example 7] Calcium chloride 30% Water 70%

[Example 8] Castor oil 85% Fluororesin powder 10% Silicon resin powder 5% In this formulation example, an agitator is attached to an autoclave, and a snow-proofing agent for roads is used which uses a liquid mixed and dissolved according to the blending example according to the blending example. Is as follows.

[Example 9] Calcium chloride 100% (or 40% calcium chloride block) First, dry the floor with tar-tar mixture at both ends of the road and dry calcium chloride or 40% calcium chloride water block

Example 9 (B) is spread to a thickness of 5 mm. On its upper surface

Example 9 The calcium chloride serassin protein solution (A) is poured and solidified. The same applies to the road at the entrance of the house. If you work during the snowfall, use a sprinkler on the road

Example 9 Solution A is sprayed. In the case of a passage, sprinkle water with funnel. When it ’s time,

[Example 9] (A) Dissolve from the contact surface with the liquid, become porous, shrink and elute. At this time, if the anhydrous calcium chloride powder is added alone or together with the carbon ash, the snow melting is quickly performed. When the temperature is -40 ° C or higher, snow can be melted by spraying hot water on the surface.

Fig. 8 shows an oblique front view of a snow-melting board on a road. The surface is a flat plate (1c) obtained by mixing sand or stone blocks with calcium chloride, moistening it with water, and hardening it. A calcium chloride plate (3c) having a bottom surface hardened by adding a small amount of water to calcium chloride particles as a serassin protein mixed plate (2c)
The laminated board of c) is shown, and the surface is non-slip. In order to attach this laminated board to the surface of a road or a passage, an asphalt board (4c) is attached as a bottom face. When the snow falls on the upper surface of the plywood, the snow is deposited, but when it comes into contact with the surface (1c), it comes into contact with the calcium chloride plate, and the snow is melted. Since the groove (5c) is engraved in advance on this surface, the snow is gradually melted.

FIG. 9 shows an oblique side view of the roof of a house, in which a large number of calcium chloride plates (1E) are attached to the upper surface of the roof (A). Then, a fluorine resin or a silicon resin film (2E) is attached to a lower portion of the calcium chloride plate (1E), and a tile or a tin plate is provided at a lower portion thereof. When snow falls, the calcium chloride plate (1E) on the roof top comes in contact with the snow and flows down, and the snow on the bottom automatically slides down. This method eliminates the hassle of falling snow. If the calcium chloride plate (1E) disappears, a new calcium chloride plate is laminated, and snow is automatically removed.

FIG. 10 shows an oblique front view of a tar pitch plate (1F) mixed with crushed calcium chloride, which can be used for roads.
When snow falls on the road, calcium chloride contacts and dissolves (1F), and the board becomes porous, but the crushed stones increase the compressive strength by 30%. The calcium chloride solution formed by calcium chloride and snow gradually penetrates into the lower inside of the (1F) plate, flows while preventing snow accumulation, and continues to dissolve even when it becomes 10% calcium chloride. If the calcium chloride disappears completely, it may be replaced. When this calcium chloride plate is loaded on the top of the roof, if you apply silicon or fluororesin paint on the surface of the tile, tin, or plastic plate in advance, the calcium chloride dissolved from the block on the top of the roof The liquid flows in the space between the roof tiles while flowing to the lower part, and slides down on the paint surface containing a pre-coated fluororesin or the like. Similar results can be obtained by applying castor oil in advance and applying a calcium chloride selasin solution, but calcium chloride must be blocked in order to prevent snow cover over one winter.
In addition, on a road surface made of a concrete block on a highway or a national road, when calcium chloride comes into contact with concrete, salt damage is caused, and corrosion of reinforcing steel by acidic calcium chloride becomes severe. To prevent this, apply a thin tar paint on the surface of the road and set up a protrusion that protrudes both ends of the road to prevent contact with the calcium chloride solution, and if the calcium chloride solution flows, use a plastic pipe to remove the solution. Collect and reuse for watering. In addition, it is stabilized by previously applying sodium pertitanate and sodium silicate as a surface treatment for concrete. Further, when the calcium chloride solid layer is slippery in winter, sand or slag powder carbon may be attached to the surface, and they may be mixed. There is no derailment when this calcium chloride selasin solution is used in combination with castor oil paint when used for train wheel covers. It goes without saying that the present invention is also applied to ships, freezers, freezer cars, and the like. In particular, when this 30% calcium chloride selasin protein or glycol solution is applied to the window glass of an automobile, it can be prevented from freezing and easily removed by wiping with a piece of cloth. This calcium chloride plate does not freeze at −20 ° C., but when it becomes 10% or less, freezing does not occur if the calcium chloride serassin protein solution is sprayed while gradually heading for freezing. Therefore, when there is snowfall after laying the cured calcium chloride serassin protein on the road, 10 to 30% of the calcium chloride solution
The spraying of the water solution causes the snow to be melted quickly, and the snowfall caused by the subsequent snowfall exhibits the snow melting efficiency within a certain period. Thus, the defrosting agent in the present invention is:

Example 8 The castor oil-based defrosting agent is applied. And when spraying the calcium chloride solution on the oil film on the surface,
The inner wall of the stocker has a castor oil-based film that has a thickness of 2 mm in one week at a humidity of 90%. The surface coating of this calcium chloride water absorbs moisture in the air, and the frosting disappears. Since the frosting agent is not sprayed, the aqueous solution of calcium chloride is further sprayed on the frosting agent to increase the concentration of calcium chloride. By repeating this process, there is almost no frosting property. In the case of calcium chloride powder having a concentration of 90% to 100%, the specific heat is high because calcium chloride is in a solid state, and frost is formed on the solid surface, so that moisture in the air is frosted on the surface of calcium chloride and goes into the interior. The result is not good because the penetration of water is suppressed. When the thickening agent serassin protein is dissolved in the calcium chloride water, the fluidity of the calcium chloride water is not small when the selasin protein increases.
Since a substance with a high concentration solidifies, it absorbs less moisture in the air and increases the degree of frosting. Also in ethylene glycol, when the concentration of calcium chloride is increased, fluidity is not obtained and crystallization occurs, so that absorption of moisture in the air is deteriorated. The concentration of calcium chloride water is 10
水 30% calcium chloride-concentrated water is the easiest to absorb moisture in the air. Also, when a 20-35% solution of this calcium chloride serassin protein solution is applied to a stocker, the calcium chloride film is frosted in 3 to 6 days, so that an alcohol solution of ethylene glycol or a titanic alcohol chelate compound is applied. Then, there is almost no frosting property. When 40% calcium chloride water is applied, white crystal fragments of calcium chloride are formed, but when ethylene glycol is applied to the surface thereof, there is no frosting property. Similar results are obtained with a titanate alcohol chelate compound. If 20 cc of an alcohol solution of glycol or titanate chelate is put into a plastic bottle in this stocker, freezing does not occur and no frosting occurs. One method is to put a liquid absorbent into the stocker because it absorbs the moisture in the air in the stocker. This is related to the thickness of the calcium chloride solution or the liquid of glycol to keep frost protection for a long time. The larger the thickness, the more frost-proof. In the case of liquid paraffin, since it does not absorb the moisture in the air, it acts in the same manner as castor oil, and when the temperature decreases, the fluidity stops and frosting occurs on the surface. Therefore, it is necessary that the surface always changes at a constant calcium chloride concentration. In the case of magnesium chloride having a high absorbency, crystallization occurs at an average of 5 to 6 ° C, and when the crystals become -5 ° C or less, the crystals become seeds of frosting. Occur. In a mixture of calcium chloride water and ethylene glycol, the solubility of calcium chloride in ethylene glycol is poor, so that salting out tends to occur and the absorption of water in the air is poor. For this reason, calcium chloride water is the most reasonable for low toxicity and low cost.
In a fish freezer requiring quick freezing such as tuna, the temperature is kept at a temperature of -30 to -40 ° C. Therefore, the efficiency of the air blowing surface of the cold air blowing screen is reduced due to freezing. When this calcium chloride water is applied to the membrane, the moisture in the air is 3 to 5 days and there is no frosting at 80% humidity. Then, a 20% calcium chloride serassin protein solution is sponged, brushed or sprayed on the surface. Applying this method prevents frosting, so if this method is adopted for freezing the lost of the large rapid freezing outlet, freezing will not easily occur, but at -50 ° C, the calcium chloride concentration will be up to 35 to 40%. It is good to raise it, but application of glycol such as ethylene glycol is also effective. In the freezing of tuna, if it is applied with a sponge impregnated with glycol, there is little frosting, and the glycol is easily removed by washing. In addition, when a liquid obtained by mixing an alcohol liquid of a titanic acid alcohol chelate compound with glycol is placed in a container in a stocker and left to stand, the partial pressure of alcohol in the stocker increases, and the partial pressure in the suspected seal in the stocker increases. The penetration of air into the stocker is reduced and the frosting property is reduced, and the penetration of moisture in the air is also reduced, so that the frosting property is low. Polyglycol obtained by adding ethylene oxide to glycol is higher in crystallinity than glycol, but has an effect of thickening the coating layer due to its high viscosity. Further, when an alcoholic liquid of a titanic acid alcohol chelate compound is put in a perforated dish and put in a freezer or a stocker in advance, there is no frosting.

As described above, when an oily liquid in which a fluorinated resin and a silicone resin are mixed with castor oil is applied, when the humidity in the air exceeds 70%, thin frosting occurs on the oily liquid surface. To prevent this, it is necessary to use salts that can sufficiently absorb moisture in the air even at a temperature of zero or less. And it is necessary for the absorbed salts to persist without freezing. For this reason, the present invention applies 10-4 to the frozen surface to which the castor oil mixed paste solution is applied.
When the thickening solution is dissolved by dissolving the serassin protein in 0% calcium chloride aqueous solution and then cooled, the anti-frost effect is further enhanced and frosting is eliminated, but after a certain period of time, this overcoat solution is again applied to the upper surface. When applied, frosting is subsequently prevented and long-lasting frost protection is maintained. In addition, those coated with the glycol liquid do not have frost. In the freezing of a sushi case with a refrigeration pipe, calcium chloride or a 20% solution of calcium chloride added with a surfactant and dispersed with castor oil is applied to the emulsion to reduce the frosting property. Slightly inferior to calcium chloride water alone. A liquid obtained by dispersing a fluororesin or a silicone resin in calcium chloride water and dispersing the same has inferior frosting properties as compared with those using castor oil or calcium chloride serasin protein. When a mixture of an alcohol solution of an ethyl titanate chelate compound and glycol is mixed and put in a container and one part is opened, the water in the stocker is extinguished by the partial pressure of the alcohol gas and is reduced, so that the frosting property is low. The combined use of a castor oil paint and a calcium chloride selasin protein solution with an alcohol glycolate solution of a titanic acid alcohol chelate compound has the effect of preventing frost formation and reducing the damage of snow cover.
Further, when alcohol is vaporized in the stocker, the alcohol glycol solution of the titanic acid alcohol chelate compound has an effect of increasing the partial pressure of alcohol in the stocker, pursuing moisture in the air, and preventing frost formation. In particular, it is more effective to add an organic solvent having a higher volatility than alcohol to the titanic acid alcohol chelate compound, but it is necessary to pay attention to the action after evacuation in order to perform the operation. When the alcoholic liquid of the titanic acid alcohol chelate compound is put into the bottom of the stocker alone to diffuse alcohol from the porous lid, the partial pressure of the alcohol in the stocker rises and the frosting property is low, and other vehicles, It is also used for refrigeration vehicles and ships. Acetone other than alcohol, acetate,
Flavors, hexane ether, etc. also increase the internal pressure inside the stocker to prevent ingress of moisture in the air, which prevents frosting.The partial pressure is increased by the combination of calcium chloride water and the former, while moisture Absorption of water does not cause frosting in the refrigerator, which saves electricity.
