Description

Forced Evaporative Humidifier {FORCED EVAPORATION TYPE HUMIDIFIER}

The present invention relates to a forced evaporative humidifier, and more particularly, to maintain a constant relative humidity in the room while avoiding condensation, so that the air is pleasantly humidified, in particular, even if the humidity is kept in a storage bin where agricultural products are stored. The present invention relates to a forced evaporative humidifier that can prevent the phenomenon of farm products from being corrupted by preventing the phenomenon from occurring.

In general, the room where people live or the inside of the reservoir was humidified by supplying water in a state that is easy to evaporate by spraying water in the form of fine particles. However, in the indoor space, even if water is supplied to the microparticles, since the water is in a liquid state, the humidification proceeds only when it is close to the sprayed position. In addition, the low-temperature reservoir where agricultural products are stored is provided with cooling means for lowering the internal temperature, and since the cooling means lowers the internal temperature in the evaporator, the surface of the evaporator installed in the reservoir is frozen by water particles, resulting in an ice layer. . At this time, the moisture in the reservoir is reduced by the generated ice, and the relative humidity in the reservoir is about 65% to 85%. As a result, the humidity in the low temperature reservoir decreases, and the moisture contained in the agricultural product evaporates into the air of the reservoir, thereby reducing the weight of the agricultural product. As such, when fruits and vegetables as well as agricultural products lose moisture, moisture is evaporated from the agricultural products to reduce the weight of the agricultural products, and excessive moisture evaporates, the epidermis dries and the state of appearance decreases, resulting in loss of commodity value. Most agricultural products lose their commercial value when the water loss is more than 5%, and their farm price is reduced due to weight loss and quality deterioration. On the other hand, crops such as ginger and sweet potatoes require high humidity environment conditions of about 90% to 98% during the curing or storage process after harvesting, and corruption occurs when the humidity is low.

Conventionally, in order to solve this problem, a heat humidifier, a centrifugal humidifier, or an ultrasonic humidifier was used to supply water into the reservoir. However, in the case of a heated humidifier, water is supplied to the air in the form of water vapor, but when water is supplied to a low temperature place such as a storage room due to the high temperature of the water vapor, not only condensation occurs but also a change in the room temperature occurs. have. In addition, in the case of centrifugal and ultrasonic humidifiers, the air is humidified in a state where water is finely granulated, so when granulated water is supplied to a low temperature reservoir, condensation occurs on the walls of the reservoir or the agricultural products being stored, and freezes on the evaporator. The amount of ice will be higher. Thus, the repetition of the defrosting process increases the temperature in the reservoir, which increases the ups and downs of the temperature in the reservoir, making it difficult to maintain the freshness of the stored produce. In addition, since both centrifugal and ultrasonic humidifiers are supplied to the reservoir in the form of droplets, even if water does not freeze in the evaporator, if dew forms in the reservoir, the growth of mold or bacteria is promoted, resulting in the decay of agricultural products. .

Thus, in recent years, not only can the room be humidified with water vapor, but also produce can store the produce while humidifying the inside of the store uniformly at 90% to 98% relative humidity conditions to prevent moisture loss, and water droplets form in the store. There is a need for a humidifier that can prevent it.

Therefore, the problem to be solved by the present invention is to provide a forced evaporative humidifier that can maintain the high humidity inside the reservoir at the same time to prevent the condensation of water droplets in the reservoir by evaporating water and supplying the water to the reservoir in a gaseous state. will be.

Water droplets can form on the plant to prevent the produce from decaying. Furthermore, since the humidification proceeds while circulating the air in the reservoir, after the humidification, the air temperature is sent out to be equal to the temperature of the reservoir, thereby preventing condensation from occurring in the reservoir. Therefore, not only the freshness of the agricultural products can be maintained for a long time, but also the quality of the agricultural products can be maintained and the weight loss can be suppressed, so that the farmhouse price can be prevented from falling.

Hereinafter, the present invention will be described in more detail with reference to preferred examples. It will be apparent to those skilled in the art, however, that these examples are provided to further illustrate the present invention, and the scope of the present invention is not limited thereto.

Most agricultural products contain between 85% and 98% moisture. Fruits and vegetables, as well as agricultural products, lose their freshness when they lose moisture. In other words, if the relative humidity in the air is too low, moisture is evaporated from the agricultural product to reduce the weight of the agricultural product, and excessive moisture evaporates, the epidermis dries and the appearance of the product deteriorates and the value of the product is lost. Most agricultural products lose their commercial value when the moisture loss is more than 5%, and the weight of the farm reduces the farmers' receiving price. Therefore, it is preferable that the agricultural products are stored at the relative humidity conditions as high as possible to prevent moisture loss.

The present invention relates to a forced evaporative humidifier (100) capable of maintaining a water content of agricultural products, including fruits and vegetables for a long time, the forced evaporative humidifier (100) according to the present invention, the air in the humidifier 200 The water (W) is in constant contact to increase the amount of water vapor contained in the air. Therefore, unlike the centrifugal forced evaporative humidifier or ultrasonic forced evaporative humidifier, the water is supplied in the water vapor state in the air so that the humid air is supplied into the reservoir.

1 is a perspective view of a forced evaporative humidifier according to an embodiment of the present invention, Figure 2 is a cross-sectional view of a forced evaporative humidifier according to an embodiment of the present invention.

In the forced evaporative humidifier 100 according to the present invention, as shown in Fig. 1 and 2, the exhaust port 114 is perforated on the upper surface, the inlet port 112 is perforated on one side of the front housing 110 ;

Located in the lower portion of the inlet 112, the water tank 120 is stored water (W);

A spray nozzle 132 located above the inlet 112, a pump P for raising water W of the water tank 120 to the spray nozzle 132, and a pump P An injection unit 130 including a transfer pipe 134 through which the water W to be raised moves;

A blowing fan 160 positioned above the injection nozzle 132 to transfer air to the exhaust port 114 side of the housing 110;

Located in the lower portion of the injection nozzle 132, the body surface 212 is formed so that the water injected from the injection nozzle 132 flows and the plurality of tubular spacers 214 protruding to the body surface 212 Humidification unit 200, the thin plate 210 including a horizontal direction laminated; And

Located between the blowing fan 160 and the injection nozzle 132, the eliminator 150 for preventing the scattering of the water droplets contained in the humidified humidifier in the humidifier 200; includes.

The forced evaporative humidifier 100 transfers the water (W) stored in the water tank 120 to the injection nozzle 132 using the pump (P). The water (W) sprayed from the spray nozzle 132 falls into the humidifier 200 located below the spray nozzle 132. Since the humidifying part 200 has a plurality of thin plates 210 formed upright, the water W is widened when the water W flows along the thin plate 210, rather than vertically falling in the air. In addition, since the blower fan 160 is located above the water tank 120, the humidifier 200, the sprayer 130, and the eliminator 150, the blower fan 160 is disposed in the housing 110. When the wind is driven toward the exhaust port 114 side, air outside the housing 110 is forced through the inlet 112 of the housing 110 by forced convection by the blower. Will pass). Here, some of the water (W) passing through the humidifying unit 200 will fall to the water tank 120 without being vaporized. As such, when the water W in the liquid state flows into the water tank 120 and the air introduced into the inlet 112 meets the water W, the contaminants contained in the water W are adsorbed onto the water. do. Therefore, the wet air discharged to the exhaust port 114 is discharged in a cleaner state than the air introduced into the intake port 112.

In addition, in order to suppress the dust in the air flowing into the intake port 112 into the forced evaporative humidifier, the dust removal filter 113 may be attached to the intake port 112. That is, the air may come in contact with the water, so that the contaminants may be washed off by the water, but the contaminants may be removed before the dust in the air flowing into the housing 110 through the inlet 112 reaches the water. have. Here, by installing the dust removing filter 113 over the entire area of the inlet 112, the air flowing into the housing 110 passes through the dust removing filter 113 to allow the humidification to proceed.

There is a constant liquefaction and vaporization between water and air. That is, water continues to change into water vapor and water into water. The rate at which these two changes proceed depends on how quickly the water evaporates. What determines this ratio depends on the relative humidity of the air touching the surface of the water. The relative humidity of air here is related to the absolute amount of water vapor and the temperature of the air. Wind means the movement of air molecules by the pressure difference. As wind moves, water vapor moves along with it. When the wind blows, the air that is in contact with the liquid is replaced with new air. Since the newly supplied air is not in contact with the liquid, the absolute humidity is lowered and the relative humidity is lower than that of the air in contact with the liquid. Therefore, when new air comes into contact with water, vaporization proceeds smoothly. Therefore, the forced evaporative humidifier 100 according to the present invention, while flowing along the thin plate 210, the water (W) having a wider surface area meets the air passing through the thin plate 210 to evaporate into water vapor. Therefore, the relative humidity of the air sent to the outlet 152b is increased more than the air introduced into the inlet 112.

Here, the blowing fan 160 is provided above the eliminator 150 in order to smoothly discharge the air with increased water vapor. In the case of the blowing fan 160, the wind speed of the front and rear is different. That is, the front of the blower fan 160 through which the wind is discharged collects the air introduced in multiple directions from the rear of the blower fan 160, so that the wind speed of the front of the blower fan 160 is higher than that of the rear of the blower fan 160. fast. Looking at the position of the blowing fan 160 in the forced evaporative humidifier 100 according to the present invention for the characteristics of the blowing fan 160 as follows. For example, when the blowing fan 160 is located below the humidifying part 200, since the wind speed is high, the water W descending on the thin plate 210 may be short in contact with the air. There is no time for (W) to evaporate. In addition, since the wind acts in the opposite direction of gravity acting on the water (W), the water (W) is moved along the thin plate 210 to prevent the surface area from widening. Therefore, even if the water (W) is exposed to the air for the same time, the surface area is reduced, so that the water (W) evaporation efficiency is reduced. In addition, the distance between the exhaust port 114 and the blowing fan 160 is difficult to smoothly discharge the humidified air.

In addition, when the blowing fan 160 is located between the spray nozzle 132 and the humidifier 200, a part of the water W discharged through the spray nozzle 132 does not move directly to the humidifier 200. Because it is scattered toward the eliminator 150, the humidification process is difficult to actively proceed. In addition, in this case, since the amount of water (W) supplied to the eliminator 150 is increased, when a larger amount of water (W) is supplied to the eliminator 150 than can be prevented from being scattered. Since some of the water (W) introduced into the eliminator 150 passes through the eliminator 150, water (W) is accumulated in the reservoir. Therefore, it is preferable that the blowing fan 160 is formed between the eliminator 150 and the exhaust port 114 so that the humidification process can be performed smoothly and the humidified air can be smoothly supplied to the reservoir. That is, the humidifier 200, the injection nozzle 132, and the eliminator 150 are located on the rear side of the blower fan 160, so that the air velocity of the air moves in the direction of water droplets even when the air moves upward. Make sure that the speed does not change to the upper direction. Therefore, the air passing through the humidifying part 200 sufficiently contacts with the water W having a large surface area without preventing the surface area of the water W from widening so that the water W can be evaporated smoothly into water vapor. . In addition, since the air passing through the eliminator 150 is a low speed, not only does water (W) mix in the air, but also prevents the pass through the eliminator (150), even if water (W) is mixed in the air, the eliminator In the process of moving the scattering prevention tube 154 of the eater 150, the air is moved at a low speed so that the air can be discharged in a state separated from the water (W). Therefore, the air including only water vapor is supplied to the rear surface of the blower fan 160, and thus the collected air is discharged to the outside of the housing 110 through the exhaust port 114, thereby preventing water W from forming in the reservoir. .

The humidifier 200 is provided with a plurality of thin plates 210. As the number of thin plates 210 increases, the surface area of the water W in contact with air may be increased. However, when the spacing between the body surface 212 is too densely installed, it is preferable that a plurality of thin plates 210 are installed at appropriate intervals because air is difficult to pass between the body surfaces 212. To this end, the thin plate 210 is preferably installed at intervals of 1.9mm to 2.5mm between the body surface 212. That is, when the distance between the body surface 212 is less than 1.9mm, the space through which air can pass is so narrow that the speed of the wind passing between the body surface 212 by the capillary phenomenon can be increased rapidly. . In this case, because the wind speed is too fast, it is difficult for water (W) to evaporate smoothly with water vapor. In addition, even if the capillary phenomenon does not occur, it is preferable that the space between the body surfaces 212 is at least 1.9 mm because the space is narrow and air is difficult to flow smoothly. In addition, when the spacing of the thin plate 210 exceeds 2.5mm, the air is smoothly humidified because the surface area of the water (W) that can be in effective contact with the air is reduced compared to the amount of air passing through the humidifying unit 200. it's difficult. Therefore, the thin plate 210 is preferably installed at intervals of 1.9mm to 2.5mm between the body surface 212.

Similarly, the thinner the thickness of the body surface 212 increases the number of thin plates 210 that can be installed in the humidifying part 200, but if the body surface 212 is formed too thin, the strength is lowered and the humidifying part 200 It is preferable that the humidification part 200 is provided with a body surface 212 having an appropriate thickness because durability of the s) is reduced. To this end, the thickness of the body surface 212 is preferably 0.1mm to 0.5mm. That is, when the thickness of the body surface 212 is less than 0.1mm, because the thickness of the body surface 212 is thin because the air passing through the thin plate 210 continuously impacts the body surface 212, forced evaporation type When the humidifier 100 is driven, noise is generated in the humidifier 200. In addition, as the body surface 212 is damaged, the durability of the humidifying unit 200 is lowered. In addition, when the thickness of the body surface 212 exceeds 0.5mm, compared to the strength required by the humidifying unit 200, the strength of the thin plate 210 is unnecessarily improved, and thus the installation space of the thin plate 210 is increased. Will be reduced. Therefore, the thickness of the thin plate 210 is preferably 0.1 mm to 0.5 mm.

A variety of spray nozzles 132 formed on the spray unit 130 may be used, but in particular, a spiral full cone nozzle (SPIRAL FULL-) capable of smoothly spraying even when dust is mixed in the air flowing into the housing 110. CONE NOZZLE) is preferably used. In particular, by using a spray angle of 90 ° to 120 °, so that water can be evenly sprayed to the humidifying unit 120. That is, when the spray angle of the spray nozzle 132 is less than 90 °, even if a plurality of spray nozzles 132 are mounted to spray the water evenly on the humidifying part 200 because the empty gap formed between the thread and the mountain is humidified. Water may be sprayed only on a portion of the 200. In addition, when the injection angle of the injection nozzle 132 exceeds 120 °, the water injection zones between the injection nozzles 132 may be excessively overlapped and may hinder the flow of air in the humidifying part 200. In addition, as the droplets injected into the small particles merge with each other, the size of the droplets increases, so that the effective contact area with the air may be reduced compared to the amount of water jet. Accordingly, the spray nozzle 132 used in the spray unit 130 may use a spiral full cone nozzle having a spray angle of 90 ° to 120 °.

The eliminator 150 forms a shatterproof tube 154 so that the inlet 152a and the outlet 152b are provided at positions displaced in the vertical direction to prevent the water droplets contained in the air from scattering. Therefore, when the air including the water (W) passes through the shatterproof pipe 154, the water (W) is attached to the bent portion of the shatterproof pipe 154, only the water vapor contained in the air and air eliminator It is possible to pass 150. In this case, in order to maximize the area of the scattering prevention tube 154 of the eliminator 150, it is preferable to form the inlet 152a and the outlet 152b in a hexagon. That is, the scattering prevention tube 154 provided between the inlet 152a and the outlet 152b is formed in a hexagonal tube shape. Therefore, water W contained in the air can be effectively removed.

Water (W) injected from the water supply nozzle is supplied from the water tank 120 located in the lower portion of the housing 110. Therefore, as time passes, the water W in the water tank 120 gradually decreases. In the present invention, the water tank 122 may be provided so that the water tank 120 is always supplied with a predetermined amount or more. Here, the water supply unit 122 may supply water (W) manually, or by providing a floating valve 126 in the water tank 120, the water supply unit when the water (W) in the water tank 120 is a predetermined amount or less Opening the 122 may allow water (W) to flow into the water tank 120. That is, when the floating valve 126 including the floating port floating on the water (W) is moved to the lower position of the floating port to open the water supply unit 122 to supply the water (W) in the water tank 120, When the float is moved to a certain height, the floating valve 126 closes the water supply 122 and stops the water (W) from being supplied into the water tank 120.

In addition, the water tank 120 further includes a sterilizing solution water supply unit 124 through which a sterilizing solution for suppressing bacterial growth and removing bacteria is contained in the air through a process in which water W is continuously circulated. The contaminated bacteria can be prevented from contaminating the water (W) while contacting the water (W). That is, the water (W) flowing into the water tank 120 while descending from the humidifying unit 200 is introduced into the water tank 120 while adsorbing contaminants of air introduced into the forced evaporative humidifier 100. As such, even if water containing contaminants is introduced into the water tank 120, bacteria or viruses are prevented from growing in the water in the water tank 120 by contaminants. In addition, by providing such a sterilizing solution, it is possible to prevent the water (W) from being caught between the thin plates 210 to allow the air to flow smoothly between the humidifying parts 200 for a long time. That is, when the water (W) containing the sterilizing liquid is supplied to the humidifying unit 200 through the injection nozzle, the humidifying unit 200 is sterilized by the water (W) containing the sterilizing liquid. In addition, in addition to sterilizing the humidifying unit 200 by the sterilizing solution, by antibacterial processing the surface of the thin plate 210, it is possible to prevent the adsorption of bacteria in the air during the process of humidifying the air. In addition to the thin plate 210, the surface of the humidifying pipes 442 and 542 described later is subjected to antibacterial treatment, thereby inhibiting the growth of the bacteria or bacteria in the humidifying unit 200, whereby the agricultural products decay due to bacteria or bacteria. Can be prevented.

When the tubular spacer 214 is provided on the body surface 212, the humidification part 200 includes a fastening tube 248 coupled to the plurality of thin plates 210 simultaneously as shown in FIG. 2. It may be further provided. Here, the fastening tube 248 is fixed to the humidifying part 200 position in a state where the plurality of laminated thin plates 210 are not disturbed from each other. Here, the water (W) of the water tank 120 may be circulated to the fastening pipe 248.

On the other hand, by providing a constant temperature coil in the water tank 120, it is possible to prevent the water in the water tank 120 falls below a predetermined temperature. That is, when the water in the water tank 120 is continuously circulated to decrease the temperature, the constant temperature coil is operated to rise back to the target temperature. By providing the constant temperature coil as described above, the temperature of the water injected into the injection nozzle 132 may be prevented from becoming too low and the temperature of the water flowing in the fastening tube may be maintained to prevent the thin plate 210 from being frozen. Here, each fastening tube is coupled in fluid communication with a sea ice water pipe 249 that receives water from the water tank 120 directly from the pump.

3 is a perspective view of a thin plate according to an embodiment of the present invention, FIG. 4 is a cross-sectional view A of FIG. 3, and FIG. 4b is a cross-sectional view B of FIG. 3.

The spacer 214 formed in the thin plate 210 may extend a flow path of air passing between the thin plates 210 in addition to maintaining a constant gap between the thin plates 210. As such, the spacers 214 are preferably arranged to be offset from each other in the vertical direction on the same thin plate 210 in order to extend the air passage. That is, the spacers 214 located above and below the one spacer 214 are arranged so that their centers are shifted upward and downward, so that the flow path is changed by the spacer 214 so that the air is thin. The thin plate 210 is moved in a path longer than the vertical length of 210. Therefore, even if the same amount of air passes between the thin plate 210 is to increase the amount of humidification.

For example, as shown in FIG. 3, when the spacers 214 are formed in three horizontal rows, the spacers 214 located in the odd rows and the spacers 214 located in the even rows are shifted from each other. Is formed. That is, even-spaced spacing 214 is located in the vertical direction between the spacing 214 located in the odd column. That is, when the thin plate 210 is provided in the humidifying part 200 in a standing state, one spacer 214 is arranged so that the center and the other spacer 214 located in the vertical direction are shifted from each other. In addition, the spacer surface 212 is provided between the spacer 214, the slot is divided into the first slot and the second slot according to the shape of the body surface 212 is perforated.

The spacer 214 formed on the body surface 212 of the present invention is provided with one end 214a and the other end 214b. One end 214a of the spacer 214 is formed to be connected to the body surface 212, the spacer 214 is formed on the body surface 212 at the position where the spacer 214 is formed, as shown in Figure 4a, The through hole 216 may be drilled in position. The spacer 214 is provided so that the plurality of thin plates 210 stacked in the lateral direction can be kept constant at a distance from each other. Accordingly, the diameter of the other end 214b of the spacer 214 may be wider than the diameter of the one end 214a of the spacer 214, and the body surfaces 212 of the adjacent thin plates 210 may maintain a constant distance from each other. As described above, in addition to forming different diameter sizes of one end 214a and the other end 214b of the spacer 214, the other spacer 214 is not inserted into one spacer 214 of the thin plate 210. If it is possible to form the spacer 214 in any structure.

Here, a plurality of slits 213 cut in the horizontal direction are formed between the pair of spacers 214 adjacent in the horizontal direction. At this time, the present invention does not merely perforate the slit 213, as shown in Figure 4b, by allowing the portion in which the slit 213 is formed, the air flows more smoothly in the front and rear direction of the body surface 212. Do it. That is, the plurality of slits 213 may include a first slit 213a in which the cutting positions 212a and 212b of the body surface 212 cut by the slit protrude toward the upper direction of the body surface 212. The cutting position 212b of the body surface 212 is formed to include a second slit 213b protruding toward the lower direction of the body surface 212. Here, the installation positions of the first slit 213a and the second slit 213b may be arranged in various ways as desired, but in one embodiment of the present invention, the first slit 213a and the first slit 213a are formed in one horizontal column. Two slits 213b are formed at the same time.

5 schematically shows the direction of movement of air and water through the thin plate.

Air moving from the bottom to the top of the thin plate 210, as shown in Figure 5a, the length of the movement path is increased by the spacer 214. Likewise, the water moving from the top to the bottom of the thin plate 210 also increases in the length of the movement path by the spacer 214. That is, with the increase in the surface area of the water that can be in contact with the air as the path of the water is longer, the air can be in contact with the water moving along the thin plate 210 of the humidifying unit 200 as the path is longer. Will increase. Therefore, even if the same amount of air flows by the spacer 214, the air can be in contact with water for a long time, it is possible to humidify the room at high humidity even at low temperatures.

The slit 213 is for increasing the flow length of air and water like the spacer 214. If the spacer 214 increases the length of the vertical movement path of the thin plate 210, the slit 213 is shown in FIG. As shown in 5b, air and water are allowed to flow through the body surface 212. Therefore, the air and water to move in the front and rear direction of the body surface 212. That is, the wind passing through the second slot moves upward while passing through the first slot, and the water passing through the first slot moves downward through the second slot. Therefore, air and water flow in the front and rear directions of the body surface 212, so that the air may contact the water for a long time. Therefore, the room can be humidified with high humidity even at a low temperature. The forced evaporative humidifier according to the present invention can be installed anywhere where air conditioning is required in addition to the agricultural product storage. That is, it can be applied to any place such as an office, a workshop, a hospital, a cold storage room and a clean room.

Relative humidity is measured. The experiment was carried out by running a forced evaporative humidifier for one hour in a reservoir equipped with a cooler at the front, and then measuring the measured humidity at each point in the reservoir. Relative humidity was measured by measuring humidity values at nine points of upper, middle, and lower layers, respectively, where the lower layer was 0.6m from the bottom, the middle layer was 1.2m from the bottom, and the upper layer was 1.8m from the bottom. The points were measured uniformly within the area from the forced evaporative humidifier installation position to the opposite wall surface to measure relative humidity. The nine points where relative humidity is measured are Front of Left (LF), Front of Center (CF), Front of Right (RF), Middle of Left (LM), Middle of Center (CM), and Middle of Right (RM), respectively. It is divided into LR (Rear of Left), CR (Rear of Center) and RR (Rear of Right) .Measure 9 points located at the upper, middle, and lower levels, and then measure the relative humidity at 9 points of each floor. Shown graphically. In addition, each point at which relative humidity is measured is shown in FIG.

Example

As shown in Figure 2 using a forced evaporative humidifier equipped with a humidification unit formed in a thin plate, the nozzle was selected STF12 nozzle of the International Nozzle Co., Ltd., at this time, the spray angle of the nozzle is 120 °, injection pressure Is 0.7 kg / cm 2. The installation position in the reservoir is the point center 225 mm away from the front wall.

Comparative example  One

In Comparative Example 1, a heated forced evaporative humidifier was used, and the heated forced evaporative humidifier used was a CompactLine model manufactured by HygroMatik, Germany. The installation position in the reservoir is the same as in the embodiment.

Comparative example  2

In Comparative Example 2, a centrifugal forced evaporative humidifier was used, and the centrifugal forced evaporative humidifier used was a model name HR-25 manufactured by Flanders Indus. The installation position in the reservoir is the same as in the embodiment. In the case of the centrifugal forced evaporative humidifier, the water is injected into the fine particles, so it is preferable not to be installed in the vicinity of the cooler, but the forced evaporation in the embodiment for comparison with the forced evaporative humidifier according to the present invention. The humidifier was installed at the location.

Comparative example  3

In Comparative Example 3, an ultrasonic forced evaporative humidifier was used, and the ultrasonic forced evaporative humidifier used was a model name DLE-US-06 manufactured by Htech (formerly Donglim Engineering). The installation location in the cellar is located in the center of the left wall, 2015mm above the floor. Ultrasonic forced evaporative humidifiers are installed on the side rather than the front of the cooler because it sprays water into fine particles. In other words, it is installed in a location that can optimally humidify the inside of the store.

Relative Humidity Measurement Results

Relative humidity at each point according to Examples and Comparative Examples 1, 2 and 3 is shown in Tables 1 to 4. The forced evaporative humidifier according to the present invention was marked as a developed forced evaporative humidifier. In addition, the contents of Table 1 are shown graphically in FIG. 6, the contents of Table 2 are illustrated graphically in FIG. 7, the contents of Table 3 are illustrated graphically in FIG. 8, and the contents of Table 4 are illustrated in FIG. 9. It was.

Based on the relative humidity measurement results of the Examples and Comparative Examples, it can be seen that the forced evaporative humidifier according to the embodiment is evenly humidified inside the reservoir compared to the forced evaporative humidifiers according to Comparative Examples 1 to 3. . Wherein the centrifugal forced evaporative humidifier corresponding to Comparative Example 2 is disposed in the same position as the example, while the ultrasonic forced evaporative humidifier corresponding to Comparative Example 3 was installed at the optimal place where the humidification occurs best. That is, Comparative Example 2 and Comparative Example 3, which are forced evaporative humidifiers for supplying water in the form of particles, were placed at the installation position and the optimum humidification position of the examples, and then compared with the examples. According to the experimental results, when water is sprayed in the form of particles to humidify the air, the degree of humidification differs depending on the location within the reservoir, even if the air is humidified, and the water particles are frozen in the cooler. It also lowers the cooling performance inside.

On the contrary, the forced evaporative humidifier according to the present invention can be humidified in the reservoir with uniform humidity because the humidifying air is supplied into the reservoir in a humid air state, so that the state of agricultural products in the reservoir can be stored uniformly for a long time.
