Description

[Detailed Description of the Invention] The present invention relates to a method for producing purified, temperature-controlled, and humidity-controlled air for indoor atmosphere control. To provide a method for efficiently producing atmospheric air that can maintain and store stored goods without losing their freshness.

Traditionally, indoor temperatures have been strictly controlled indoors, especially in refrigerators, and fresh foods such as vegetables, root vegetables, and fruits, as well as perishables such as yeast, have been stored at the lowest temperature possible. has been done. Low-temperature storage is used for this purpose, but conventional low-temperature storage has the sole purpose of maintaining a predetermined low temperature, and its structure is mostly sealed, with an air cooling system using Freon gas. It is used for cooling. For this reason, the air inside the refrigerator condenses moisture when it comes into contact with the cooling pipes, and then the temperature rises due to the amount of heat brought in by the stored materials and the influence of the outside air.As a result, the inside of the refrigerator is always dry, and the stored materials gradually become hydrated. This results in loss of freshness and dryness. On the other hand, it is well known that the solidified water drips and wets the surrounding area, causing the growth of mold, etc. that are resistant to low temperatures, making it difficult to manage the refrigerator. In order to prevent this, products are packaged with thin films such as vinyl, but it is impossible to completely prevent the above phenomenon. A method has been proposed in which the container is cooled by dropping the container along a line and using cold water, but this method has the disadvantage that the interior of the refrigerator gets wet and cannot be applied to general products.

The present inventor installed an air processing device having a basic structure of a cyclone structure capable of cleaning, temperature and humidity control of air outside the storage room. By producing air and supplying it into the storage chamber, the above-mentioned drawbacks of conventional refrigerators have been successfully overcome.

As described above, the present invention relates to a method for producing purified, temperature-controlled, and humidity-controlled air for atmosphere management of refrigerators and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below along with an illustrated air treatment apparatus suitable for implementing the present invention. In the drawings, arrow A indicates the flow of air, arrow H indicates the flow of hot water, and arrow W indicates the flow of water for spraying.

Referring first to FIG. 1, there is shown an example of a cyclone type air treatment device 15 suitable for practicing the present invention. The air suction pipe 1 is installed in a tangential direction with respect to the outer circumference of the outer cylinder, that is, the annular cylinder 2 constituting the cyclone, and therefore the air flows through the annular cylinder 2.
It is blown into the air so that it descends in a swirling manner. Inside this annular cylinder 2, the blown air circulates for a long period of time, while the high-pressure water pipe 12 and the spray nozzle 1
Exposure to the water spray from 3 removes contaminants such as dust contained in the air and humidifies it. Then, the purified air, which has a relatively light specific gravity, ascends through the inner cylinder, that is, the air rising cylinder 3, constituting the cyclone, and is sent through the delivery pipe 4 to a predetermined location, that is, the air-conditioned room. A fluid passage, that is, a hot water annular cylinder 9 is provided between the outer periphery of the annular cylinder 2 and between the annular cylinder 2 and the air rising cylinder 3.
and 10 are arranged. Therefore, when the air passes through the annular tube 2 and the air riser tube 3, the air is heated by sufficiently indirectly exchanging heat with the hot water.
Contaminants such as dirt and dust removed by the annular cylinder 2 are discharged through the pipe 5, valve 6, and pipe 7 together with water from the spray nozzle 13. Although hot water has been explained above, it goes without saying that if cold water is used instead of hot water, the air will be cooled.

Referring now to FIG. 2, another example of a cyclone-type air treatment device 20 suitable for carrying out the present invention is shown. The air blowing pipe 26 is attached tangentially to the outer periphery of the outer cylinder, that is, the annular cylinder 27 constituting the first cyclone, so that air is blown into the annular cylinder 27 so as to descend in a swirling manner. In this annular tube 27, the blown air is exposed to water spray from a high-pressure water pipe 52 and a spray nozzle 53, and contaminants such as dust contained in the air are removed and humidified. .
Then, the purified air, which has a relatively light specific gravity, rises through the inner cylinder, that is, the air rising annular cylinder 21 that constitutes the first cyclone, and is blown from the blow pipe 22 into the outer cylinder, that is, the annular cylinder 23 that constitutes the second cyclone. be included. The blowing pipe 22 is attached tangentially to the outer circumference of the annular tube 23, so that air is blown into the annular tube 23 in a downward spiral manner. That is, a cyclone action is performed. The air is completely removed in this annular cylinder 23 and sent to a delivery pipe 25 through an inner cylinder constituting the second cyclone, that is, an air rising cylinder 24, and from there to a predetermined place, that is, an air-conditioned room (as shown in the figure). (omitted) etc. A fluid passage, i.e., hot water rising annular cylinder 57 , is provided on the outer periphery of the annular cylinder 27 , a fluid passage, i.e., hot water descending annular cylinder 48 , between the annular cylinder 27 and the annular cylinder 21 , and a fluid passage, i.e., between the annular cylinder 21 and the annular cylinder 23 . The hot water rising annular cylinders 50 are arranged concentrically. The annular cylinder 57 and the annular cylinder 48 communicate with each other through a communication path 58, and the annular cylinder 48 and the annular cylinder 50 communicate with each other through a communication path 49. A heat exchange chamber 37 is disposed below the first cyclone, and a heat radiation pipe 41 is disposed within the heat exchange chamber 37. Heat exchange room 3
The hot water heat-exchanged in the pipe 7 passes through a pipe 42, a three-way valve 43, a pipe 44, and is sent from a pipe 46 to an annular cylinder 47 by the action of a pump 45. Subsequently, the hot water flows from the annular tube 47 to the communication path 58 and the annular tube 4.
8 and the communication path 49 to the annular cylinder 50. Further, water passes from the annular tube 50 through a recovery pipe 54, a part of which is recovered into the heat exchange chamber 37 through the pipe 51, and the rest is sent from the pipe 55 to the pipe 44 through the three-way valve 43. With the above configuration, air flows through the annular cylinders 27, 21,
and 23, the air passes through the annular cylinder 5
7, 48, and 50, and heat is indirectly exchanged with the hot water flowing through them to warm the air. Contaminants such as dust contained in the air are removed by the annular tube 27 and discharged together with water from the spray nozzle 53 through the discharge pipe 31, valve 32, and pipe 33. In addition, the water completely removed and collected in the annular tube 23 is transferred to the discharge pipe 2
8, is discharged through valve 29 and pipe 30. Further, annular cylinders 57, 48 and 50 through which hot water passes.
A spiral partition plate 56 is arranged inside.
Guide the flow of hot water. Therefore, the hot water can flow evenly throughout the fluid passage, that is, within the annular cylinder, and the efficiency of heat exchange can be improved. Heat exchange room 37
When the hot water inside is sprayed from the spray nozzle 59 into the annular cylinder 27, [In order to prevent the hot water from being sprayed, a structure that allows the spray nozzle 59 to be closed, such as a structure provided with a valve etc., may be used. Water (not shown) can be replenished from the pipe 34, valve 35 and pipe 36. In addition, pipe 38, valve 39 and pipe 4 are used for drainage.
0 is set.

Although hot water has been explained above, the heat dissipation pipe 41
By replacing the pipe with a cooling pipe, cold water is sent instead of hot water, and it goes without saying that heat exchange can be performed to cool the air.

Referring now to FIG. 3, there is illustrated yet another example of a cyclone type air treatment apparatus suitable for carrying out the present invention. In this embodiment, a plurality of cyclone-type air treatment devices shown in FIG. 1 are arranged in series (three in the drawing), and the details are the same as the cyclone-type air treatment device shown in FIG. Therefore, I will briefly explain it. Contaminated air A passes through a first cyclone type air treatment device. That is, air A is sent from the blowing pipe 60 to the pipe 63 through the outer cylinder or annular cylinder 61 and the inner cylinder or air rising cylinder 62. The air is then sent to a second cyclone-type air treatment device. Air A is pipe 6
3, the air is sent to a pipe 69 through an outer cylinder or annular cylinder 67 and an inner cylinder or air rising cylinder 68. lastly,
Air is sent to a third cyclone-type air treatment device. Air A is passed from the pipe 69 to the outer cylinder or annular cylinder 73 and the inner cylinder or air rising cylinder 74.
is sent to pipe 75 through. From here, the air A is sent to a predetermined location, that is, an air-conditioned room (not shown). Of course, a large number of cyclone type air treatment devices can be arranged in series as desired. The hot water H is sent from the inlet pipe 79 through the inlet branch pipes 80, 81 and 82 to the fluid passages or hot water annular cylinders 83, 84 and 85, respectively. Then, the hot water is heated through the hot water annular cylinder 8.
3, 84 and 85, it is collected into a collection pipe 92 through collection branch pipes 89, 90 and 91, respectively. Further, the high pressure water W is sent from the spray pipe 93 to spray branch pipes 94, 95 and 96, and then to spray nozzles 97, 98 and 99.
The liquid is sprayed into the annular cylinders 61, 67, and 73, respectively. The sprayed water humidifies and cleans the air and then passes through pipe 64, valve 65 and pipe 66, pipe 70, valve 71, and pipe 7.
2, and pipe 76, valve 77 and pipe 7
8 and are discharged respectively.

Although the case where hot water is flowed through the feed pipe 79 has been described above, it is of course possible to flow cold water instead of hot water to exchange heat with the air and cool the air. By arranging several cyclone-type air treatment devices in series in this way,
The temperature can be controlled very accurately and the air can be purified more reliably.

Because of the above configuration, the cyclone type air treatment device of the present invention has a simple and strong structure and is less likely to break down. In addition, since it is a cyclone type, it has high thermal efficiency and can completely separate dust, dust, etc., resulting in extremely clean air.
