Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is a method for storing foods and various industrial products in a refrigerator,
Air cooling device used for cold storage.

(Prior Art) Many refrigeration devices are used in fields such as the food industry, chemical industry, and distribution industry.

Conventionally, this type of cooling device has used an air-refrigerant heat exchanger using a refrigerant (for example, chlorofluorocarbon gas) to cool the inside of a refrigerator. In some cases, the inside of a refrigerator is cooled by an air-secondary refrigerant heat exchanger that completely sprays cold water cooled by a refrigerator system into the cooler.

(Problem to be solved by the invention) However, due to power, in recent years, objects that are kept refrigerated are
Particularly in the food industry, there is a need to maintain freshness and humidity of the quality of food products.
Due to the increased proliferation of bacteria, it has been difficult to maintain the freshness and humidity of refrigerated items.

This is because the conventional idea of refrigerated storage was to extend the shelf life by keeping refrigerated items at a low temperature, but there was no idea of actively maintaining humidity or killing the items. Met. or.

Negative ions that have a favorable effect on fresh foods can be added to the atmosphere in a rough atmosphere in an appropriate amount, for example 150 oct/CC, to prevent the surface of fresh foods from being damaged and to reduce the amount of electrons on the surface of fresh foods. Nothing was done to prevent failure.

(Objective of the Invention) The present invention provides an air cooling device that creates an atmosphere containing favorable temperature, humidity, sterility, and negative conditions for objects to be refrigerated by performing cooling, humidification, and sterilization. It is about providing.

Further, according to the present invention, there is provided a case having a gas inlet and an outlet, an ion supply means for generating and supplying positive and negative ions, particularly ozone ions, in the case, and spraying cold water in the case. cold water spraying means and +q'1i
i6 An air cooling device is provided which includes a cooling means and a rotating electromagnetic field processing means, which are disposed upstream of the cold water distribution means and which cool the cold water and treat it with a rotating electromagnetic field.

(Function) Inside the case, positive and negative ions, especially ozone ions, are supplied by the ion supply means, and cooling water is sprayed by the cold water spraying means. The positive ions are sterilized by ozone, the positive ions are adsorbed by the cold water because they are floating particles, and the negative ions are adjusted to an appropriate concentration by the cold water, and are further cooled and humidified by the cold water.

As a result, the air inside h can be sterilized, dust removed, added with negative ions, cooled, and humidified by the refrigeration device of the present invention.

(Examples) Hereinafter, the present invention will be specifically described based on illustrated examples.

FIG. 1 is a schematic diagram of an air cooling device equipped with ion supply means, cold water distribution means, and gold according to the first invention.

In the figure, 12 is an air cooling device, which includes a case 1 equipped with a gas inlet 11a and an outlet 11b', and an ion supply means 2 for supplying positive and negative ions, particularly ozone ions, into the case 1. The cooling water spraying means 4 is configured to spray cooling water into the case 1.

The case 1 is installed inside the refrigerator ff1i:13, and is connected to the differential 181 and the rotating electromagnetic field generator 9 outside the refrigerator 13 via piping 14. It is connected to a water cooler 10.

Various types of ion supply means 2 can be considered.

For example, there are germicidal lamps that use ultraviolet rays, or lamps that apply a high-voltage alternating current electric field between parallel electrodes to positively and negatively ionize the air passing between the parallel plate electrodes, producing ozone in particular. The cold water spraying means includes a water cooling system [10] that cools the water to, for example, around 0@C, a pipe 14a that leads the cooling water to the case 1, a spray nozzle 4 that sprays the cooling water into the case 1. A water tank 7 temporarily receives cooling water that has cooled the air, and the cooling water is sucked from the water tank through a pipe 14b.

It consists of a pump 8 that pumps the water under pressure, and a rotating electromagnetic field generator 9 that passes the cooling water pumped by the pump 8 through a rotating electromagnetic field and processes the rotating electromagnetic field.

The air cooling device according to the present invention is constructed as described above, and its operation will be explained below.

When the blower 6 in the air cooling device 12 operates, the air in the refrigeration side 13 flows through the air intake port 11a to the ion supply device 2. The air is circulated through an air-chilled water heat exchange device formed by a spray nozzle 4, an eliminator for removing water droplets, a 5° blower 6, and an air outlet ttb.

On the other hand, cooling water is supplied from the water tank 7 to the pipe 14 through the pump 8.
It is sucked into Mt-, and the pump 8 generates a rotating electromagnetic field generator 9.
After being pressure-fed to water, it is cooled down to a predetermined temperature by a water cooler 10, and passed through a pipe 14a to a spout 1/- nozzle 4.
The air is then distributed into the air cooling device 12 and circulated again.

At this time, since the cooling water is disposed perpendicularly across the rotating electromagnetic field generated in the one-rotation electromagnetic field generator 9, it is subjected to electromagnetic fluid action. That is, electric fields generated by Lorentz force, minute eddy currents, and Maxwell's equations ionize the salts in the cooling water, and the electromagnetic field also acts as a generator for bacteria in the cooling water. For this reason, as is known in the magnetic treatment of water, prevention of scale generation, sludge generation, bacteria and debris generation, and sterilization effects occur. The reason why a rotating electromagnetic field is used is that it can transmit electromagnetic effects more efficiently than the static electromagnetic field used for general magnetic treatment of water. For this reason, the air cooling system 12 of the present invention is replaced with sterile cooling water. This sterile state is further enhanced by the ozone generated by the ion supply device 2 injecting the cooling water (C solution).

Experiments have confirmed that this cold water, which has been treated in the field to improve its taste, has a weak alkali level of 18P H7.5 to 8.0, and for this reason, the cooling water as a whole Since the weight of negative ions is greater than the weight of positive ions, this cooling water flows through the air cooling device 12 from the spray nozzle 4.
It has been confirmed through experiments that if the glass ions in the airflow are dispersed inside the refrigerator 13, the average concentration of liner 241 at 1 degree will be about 1500 ke/CC. .

In this way, the air in the refrigerator 13A is transferred to the air cooling device 1
．． ．． : By passing through the air repeatedly for 1 meter, ozone generated by the ion supply device 2 sterilizes the air, and floating dust particles in the air are positively ionized, so they are collected with cooling water. The air contains many negative ions, and is cooled to an appropriate temperature and humidified by the cooling water sprayed from the cooling water spray nozzle 4. Naturally, the large droplets of cooling water sprayed from spray nozzle 4 are eliminator 5.
removed from the air stream by

The air flow inside the refrigerator 13 equipped with the air cooling device of the present invention is sterilized, dust removed, and added with negative ions.

Since the refrigerator 13 is cooled and humidified, the freshness of stored items in the refrigerator 13 can be clearly improved compared to those using a conventional cooling device.

Although the present invention has been described above based on the illustrated embodiments, the present invention is not limited to only those shown in the embodiments, and various modifications can be made within the scope of the spirit of the present invention. are not excluded from the scope of the present invention.

(Effects of the Invention) As described in detail above, according to the present invention, the atmosphere of the object to be refrigerated is kept at low temperature, high humidity, and sterile.

Since it is possible to maintain a state containing negative ions, it is possible to industrially impart a protective effect to refrigerated items, which was not possible with conventional cooling devices.
