Abstract

The present invention discloses a method and a system for preventing the dew condensation in order to prevent condensation in a reservoir such as an ammunition bin or an archive. The present invention establishes an air treatment space that is separated from an enclosed reservoir, and forcibly converts the air in the air treatment space into an air treatment apparatus so as to be dry below a predetermined humidity where condensation is unlikely to occur. Condensation in the storage is prevented by injecting dry air in the space into the storage, and discharging the humid air in the storage to the outside of the storage by the difference in density. The injected air is converted into high-density air in the low temperature dry state and injected into the bottom of the storehouse, so that hot and humid air is floated and discharged to the ceiling, or converted into low-density air in the high-temperature dry state and injected into the upper part of the storeroom. As a result, the high temperature and low humidity air is lowered and discharged to the lower part of the wall.

The present invention can effectively and economically solve the problem of condensation of the reservoir with energy that is much smaller than the energy required to increase the temperature in the reservoir, and can keep the reservoir dry for a long time, so intermittent operation is sufficient, especially condensation occurs seriously. It is suitable for ammunition which requires a lot of storage capacity.

The present invention provides a method for preventing condensation in a reservoir for removing moisture existing in an interior of a closed building such as an ammunition warehouse, an archive, an underground library or an underground library, and an ossuary. In particular, the system relates to an air treatment space that is separated from a reservoir, and converts the characteristics of the air in the air treatment space into an air treatment device so as to have a desired temperature and humidity without condensation. The present invention relates to a method and a system for preventing dew condensation in a reservoir that can be economically and reliably prevented from being condensed in the storage by pushing the inside of the storage at a time.

The air contains some (about 1%) water vapor, which is a gaseous state that mixes in the air and wanders well. The maximum amount of water vapor contained in the air (saturated state) varies depending on the temperature under the same air pressure. The higher the temperature, the higher the amount of saturated steam in the air, and the lower the temperature, the lower the amount of saturated steam.

The ratio of the saturated water vapor to the actual water vapor content at a certain temperature, expressed as a percentage, is called relative humidity (commonly referred to as 'humidity'). If the relative humidity is 100% (saturated), the air is no longer steam at a given temperature. You will not be able to include.

Therefore, if the amount of water vapor contained in the air at the same temperature is higher than the saturation state or the temperature is lowered in the saturation state, the excess water vapor is no longer mixed with air in the water vapor state and condensed into water, and the relative humidity at this time The temperature at 100% is called dew point, and this phenomenon is called condensation.

This condensation is common around us and causes many problems. For example, it is easy to see the condensation of water droplets on the indoor wall due to the temperature difference between indoors and outdoors, etc., which is caused by the temperature of the water vapor being lowered below the dew point by contact with the low temperature wall surface. It also causes mold. In particular, condensation is more severe in places where ventilation is poor, such as behind the cabinet.

Of course, condensation can be prevented to some extent by improving the heat insulation of the wall surface to raise the surface temperature above the dew point of the indoor humid air, and by appropriately ventilating to prevent the stagnation of the humid air and to suppress the generation of moisture in the room. However, due to the structural characteristics of the storage, it is very difficult to prevent condensation only by insulation and ventilation only when it is difficult to ventilate smoothly or when a large number of items are stored in the storage.

In particular, once the conditions inside the condensation occurs, circulating the air by ventilation causes more wet air contact, causing condensation to occur continuously, causing water to flow down the floor. It causes symptoms.

In addition, condensation prevention is very important in the case of ammunition, archives, ossuaries, underground libraries, museums and underground common areas where close storage and high preservation are required.

Among these, the case of the ammunition which condensation is recognized as a very serious problem is described as follows.

Generally, the ammunition tank is located in the basement or on the ground, but most of it is covered with soil so that it is buried in the ground and exposed only the front part where the explosion-proof door is installed. A vent is provided under the explosion-proof door and a non-powered exhaust fan is provided at the rear of the roof.

For this reason, the internal temperature of the ammunition warehouses is relatively low in summer and high in winter, showing a relatively large temperature difference between the two. Figure 1 shows the temperature distribution inside the conventional ammunition (C) in the summer, as can be seen in the figure the air temperature in the front of the vent (S) is relatively high, but the exhaust fan toward the rear away from the vent (S) The farther away from (F) the lower the temperature is, the greater the temperature difference is from outside (about 30 ℃).

This shows that the conventional ammunition (C) is not efficiently ventilated, and condensation may occur in quite a large area of the ammunition (C) as shown in the drawing when hot and humid air from outside the summer is introduced. Indicates that it can.

Figure 2 shows the storage of the ammunition in the existing ammunition (C), and at the same time shows the formation of the air layer inside the ammunition (C) and the flow of air. Ammunition (A) is not stored in the front of the ammunition (C) to facilitate storage and discharge is mainly stored densely packed in layers from the rear of the ammunition (C) bar, vent hole (S) under the explosion-proof door (D) Air introduced from the outside is blocked by a pile of ammo (A) receives a large flow resistance is not enough flow to the rear of the ammunition (C).

As a result, there is virtually no air flow in the rear and bottom of the ammunition tank (C). Therefore, the area where the ammunition (A) is densely stored in the ammunition tank (C) has a low temperature and high humidity and a high humidity layer (A _L ). To form.

However, the low temperature and high humidity air layer A _{L in} the ammunition tank C thus formed is higher in density than the high temperature and high humidity air layer A _{H in the} ammunition tank C as well as compared to the high temperature and high humidity air in the ammunition tank C. It is distributed at the bottom.

Therefore, even if the outside air flows through the vent (S), convection does not occur in the lower rear portion of the ammunition (C), and the introduced high temperature outside air flows into the low temperature and humidity air layer (A _L ) around the ammo (A). As it does not penetrate and rises immediately above and is discharged to the outside through the exhaust fan F, the low temperature and humidity air layer A _L inside the ammunition C is not discharged, but rather, only the external moisture is supplied.

Therefore, when hot and humid outside air flows in summer, condensation occurs due to a drop in saturated steam pressure when it meets the low temperature air in the ammunition tank (C). In particular, the condensation phenomenon occurs at the surface of the ammunition (A) having a lower temperature and high thermal conductivity. In this case, the temperature of the hot and humid air is sharply lowered, so that a large amount of water vapor contained therein forms condensation of water (M) on the surface of the ammunition (A).

Therefore, in the summer condensation is continuously generated, the surface of the ammunition (A) is always buried in the water (M), this water (M) is easily caused by the corrosion of the ammunition (A).

On the other hand, since the low-temperature dry air is introduced from the outside in winter, hot and humid air around the ammunition (A) is pushed out by the density difference, bar condensation on the surface of the ammunition (A) hardly occurs in winter. At this time, the high temperature and high humidity air around the ammunition means a high temperature in comparison with the outside air, and represents the same air as the low temperature and high humidity air layer A _L described above.

However, if the surface of the ammunition (A) is already wet in the summer and the corrosion has started, the surface corrosion of the ammunition (A) continues to proceed even in winter. After a certain period of time, discard the ammunition (A). Disposal or removal of all ammunition (A) must be carried out periodically to scrape and repaint.

On the other hand, various solutions have been sought to solve this problem, but in most cases, the relative humidity is lowered by increasing the temperature inside the reservoir, installing a dehumidifier in the reservoir, and putting another metallic material inside the reservoir. In order to disperse condensation, research has been conducted.

Increasing the temperature inside the reservoir to reduce the relative humidity has not achieved the effect in most of the reservoirs, because the internal temperature of the reservoir rises only when it is raised up to the temperature of the heavy storage material in the reservoir. Even if you try to raise the temperature of a heavy material only a lot of heat energy is necessary because it is not economical.

For example, ammunition stores hundreds of tons of ammunition, and because air is in contact with them, it is almost impossible to increase the temperature of the air without raising the temperature of the ammunition. It takes a lot of energy. Therefore, the method of installing the heater inside the ammunition, or the way to install the electric coil on the floor did not have an effect.

In addition, the use of dehumidifiers has not been achieved, for the same reason that existing reservoirs cannot push dense air into less dense air.

In other words, the air introduced into the dehumidifier is in contact with a low temperature object and the humidity of the air is converted into water in the form of the above-mentioned surface condensation, so the humidity is lowered, but as it is released from the dehumidifier, it passes through the heating plate at the rear of the dehumidifier. There is a problem in that the temperature is released higher than the incoming ambient air.

Because of this, the dehumidifier does not have a great effect in the place where the object is stored, especially when a lot of things are stored densely inside, such as an ammunition.

Because the air emitted from the dehumidifier is lighter than the surrounding air, it rises to the upper part of the reservoir, and the incoming air also has a relatively high temperature of light hot air, which is relatively easy to flow. This is because the low temperature and humidity air between the parts of the part has little flow and remains dehumidified.

If the air between the stored objects is sucked into the dehumidifier and the discharged air is sent between the objects, the size of the gap between the objects will depend on the size of the gap between the objects. The energy required to run the dehumidifier is simultaneously consumed, resulting in inefficiency.

Finally, there is a research result that induced the dew condensation on the surface of the metal by putting a metallic material with excellent thermal conductivity inside the reservoir. This method works well in the absence of water on the metallic material, but if the water persists, the effect is significantly reduced.

This is because when the condensation occurs on the metallic material, the thermal conductivity of the metal decreases, and since the metal absorbs heat generated by water condensation and the temperature of the metal rises, the temperature of the metal matches the temperature of the stored object. Because it is in equilibrium.

Therefore, the dehumidification effect of this method decreases with time, and consequently, condensation occurs in the same state as the object stored inside, and it only has the effect of dividing the total amount of condensation generated inside the store. The degree of condensation on the surface of the object is about the same.

This method requires putting as much metallic material as possible relative to the amount of goods stored, which does not serve the original purpose of the store being to store certain things in the store. For example, adding a small amount of ammunition to an ammunition bin and adding a lot of condensation-protecting metallic material can reduce the total amount of condensation on the surface of the ammunition, but over time, the degree of condensation on the surface of individual ammunition can be reduced. This is because the level is almost equal.

In addition, measures have been devised to store the items stored in the storage bins sufficiently to facilitate ventilation in the storehouses.However, when storing the cartridges sparingly, many ammunition bins must be constructed in proportion to the storage of the cartridges. There is a problem of enormous rent and construction cost, so it is not practical for practical use.

The present invention has been devised to solve the above-mentioned conventional problems, and is not limited to the loading density of the internal loads, but also does not continuously operate and sporadically operates as needed, thereby effectively removing moisture present in the reservoir. It is an object of the present invention to provide a method for preventing condensation in a store that can reliably prevent condensation in the store.

The valve poppet 49 is installed in a substantially reverse conical shape inside the valve body 48 and has an operating margin that can be operated between the valve body 48 and the valve body 48 as the piston plate 41 moves up and down.

Exhaust means 50 may be configured in various forms, but preferably made of a so-called pressure-driven check valve that is automatically opened and closed according to the internal pressure of the reservoir 10 as shown in FIG. Exhaust and prevent the inflow of outside air.

To this end, the exhaust means 50 is a cylindrical valve body 51 which is installed in the exhaust hole 13 of the reservoir 10 and the inlet 51a of the valve body 51 in accordance with the internal pressure of the reservoir 10. ) And a protective film 54 on a mesh for preventing the entrance of the valve plate 52 and the valve plate 52 while preventing the separation of the valve plate 52 and the like.

The valve plate 52 is configured to have an outer diameter smaller than the inner diameter of the valve body 51 to form the discharge passage of the airflow, and is mounted on the support jaw 53 formed at the inlet 51a of the valve body 51. The valve plate 52 is made of a thin and light plastic or rubber, and is mainly easy to use a circular shape, but may be configured in a quadrangular shape.

The upper part of the valve body 51 is provided with a protective roof 55 in order to prevent rain or snow from functioning as the exhaust means 50 or to prevent water from flowing into the reservoir 10. Accordingly, the valve body 51 is provided. The exhaust port 51b of) is formed around the valve body 51.

On the other hand, the reservoir condensation prevention system of the present invention is controlled by a central control device (not shown), for each of the sensors 15, 16, 28 and 29, the air treatment device 30 and dry air Injection device 40 is circuitally connected to the central control unit. In addition, the central control unit stores basic data regarding the internal state of the humidity of the storage 10 necessary for the prevention of condensation and the humidity and temperature of the drying air to be injected.

Next, the operation of the first embodiment of the storage condensation preventing system according to the present invention configured as described above will be described.

First, the humidity and temperature sensors 15 and 16 installed in the storage 10 continuously detect the state of the inner space 11 and send it to the central controller. Then, the central control unit compares the humidity and temperature of the storage 10 with the stored basic data, and transmits an operation signal to the air treatment device 30 when the detected humidity is determined to be a dangerous humidity of dew condensation.

Accordingly, the air treatment device 30 is operated to convert the air in the processing chamber 23 of the air treatment space 20 into low temperature dry air.

In more detail, this process, the refrigerator 39 of the air treatment device 30 is driven in accordance with the signal of the central control unit to cool the temperature below the predetermined temperature while circulating the air in the cooling housing (31). At the same time, the blower 33 of the air treatment apparatus 30 circulates the air in the lower chamber 23b of the treatment chamber 23 of the air treatment space 20 with the dehumidification unit 32. At this time, the circulation of the air in the processing chamber 23 is in the direction of suction from the upper portion of the lower chamber 23b and re-introduced into the lower portion of the lower chamber 23b. Because.

Then, the air sucked from the processing chamber 23 passes through the dehumidification unit 32 and cools while exchanging heat with the cold existing in the cooling housing 31. At the same time, the water vapor in the processing air is reduced in accordance with the temperature drop. And condensation on the inner surface of the upper condensation chamber 35, wherein the salt contained in the treated air is also removed with the condensate.

In particular, the wiper 37 continuously wipes the condensed water condensed on the inner wall of the upper condensation chamber 35 so that the inner wall of the upper condensation chamber 35 is always kept clean, so that water vapor in the treated air more easily condenses. Dehumidification takes place.

On the other hand, the condensed condensate flows to the lower part and is collected in the lower drain chamber 34, and when the water level reaches a predetermined level, the drain valve 34b is opened by the water level sensor 34c and discharged to the outside.

When such an operation is continued for a predetermined time and all the air in the processing chamber 23 of the air treatment space 20 is converted into low-temperature dry air, the humidity sensor 28 and the temperature sensor 29 installed in the piston plate 41 are changed. The state is sensed and transmitted to the central control unit, and accordingly the central control unit sends the stop signal of the air processing unit 30 and sends the operation signal of the dry air injection unit 40.

Then, the forward and reverse drive motor 44 is driven in the forward direction to release the drive wire 46 wound on the reel 45, whereby the piston plate 41 hanging on the drive wire 46 is lowered by its own weight. Will go down.

When the piston plate 41 is lowered, the low-temperature dry air is pressed by the volume reduction of the lower chamber 23b, and thus the valve poppet of the first check valve 43 installed in the piston plate 41 is reduced. 49) moves upward to block the upper valve hole 48a of the valve body 48, so that the low temperature dry air of the lower chamber 23b does not flow out into the upper chamber 23a and continues to be pressurized.

Therefore, the check valve plate 26 in which the low temperature dry air in the lower chamber 23b of the processing chamber 23 shields the dry air injection slot 25 under the heat insulation wall 21 as the piston plate 41 descends. The pressure is applied to the bottom of the inner space 11 of the reservoir 10 while opening the check valve plate 26.

At this time, since the temperature of the low temperature dry air that is pushed into the inner space 11 is heavier than the high temperature and high humidity air in the inner space 11, the existing high temperature and high humidity air in the inner space 11 is buoyant due to the density difference. It is pushed up. The hot and humid air pushed to the upper portion of the inner space 11 is discharged out through the exhaust means 50 provided in the exhaust hole 13 of the ceiling 12.

That is, when the low-temperature dry air flows from the air treatment space 20, the air pressure in the reservoir 10 rises and becomes larger than the atmospheric pressure. Accordingly, the valve plate 52 having a high temperature and humidity bet to be pushed up by the density difference is light. Pushed up).

Then, the inlet 51a of the valve body 51 is opened by the weight of the valve plate 52 falling off from the supporting jaw 53 which is in close contact with the supporting jaw 53. As a result, the hot and humid bet which is pushed by the low temperature and dry air escapes through the exhaust port 51b.

Subsequently, when the hot and humid bet is sufficiently discharged and the pressure in the reservoir 10 falls back to the atmospheric pressure, the valve plate 52 is seated on the supporting jaw 53 again by its own weight, and thus the inlet 51a of the valve body 51 is provided. Blocking will block the inflow of outside air.

On the other hand, when the piston plate 41 is lowered, the upper chamber 23a of the processing chamber 23 partitioned by the piston plate 41 is lowered in pressure due to an increase in volume, thereby forming a low pressure. Air outside the reservoir 10 is sucked into the upper chamber 23a of the processing chamber 23 of the air treatment space 20 through the suction pipe 27.

After the piston plate 41 reaches the bottom of the processing chamber 23 and injects the low temperature dry air into the inner space 11, the forward and reverse driving motor 44 is driven in the reverse direction to wind the driving wire 46. As a result, the piston plate 41 is raised to the initial position.

Then, since the pressure no longer acts on the lower chamber 23b of the processing chamber 23, the open check valve plate 26 is rotated downward by its own weight around the hinge at the upper end thereof and formed on the heat insulating wall 21. The dry air injection slot 25 is closed, so that the air in the internal space 11 cannot flow back into the air treatment space 20.

When the piston plate 41 is raised, the valve poppet 49 of the first check valve 43 installed therein moves downward under pressure to close the lower valve hole 48b of the valve body 48. The upper valve hole 48a is opened.

Therefore, air in the upper chamber 23a of the processing chamber 23 flows through the upper valve hole 48a and the vent hole 48c of the first check valve 43 while the piston plate 41 is raised. Since the pressure is increased, the pressure change does not occur in spite of the volume reduction of the upper chamber 23a, and the same is true of the lower chamber 23b in which the volume increases. This is, after all, the same as moving only the piston plate 41 to the upper portion of the processing chamber 23 while the air does not move.

In this case, the air in the processing chamber 23 of the air treatment space 20 is filled with air outside the reservoir 10.

On the other hand, the amount of air discharged from the inner space 11 of the reservoir 10 is equal to the amount of air stored in the lower chamber 23b of the processing chamber 23 of the air treatment space 20, the air treatment space 20 The low temperature dry air pushed into the inner space 11 in the air is different in density from the existing air and thus remains at the bottom of the inner space 11 while forming a layer.

Therefore, in the most ideal case, the amount of air in the lower chamber 23b of the processing chamber 23 of the two air treatment spaces 20 and the amount of air in the storage space 10 of the reservoir 10 are the same, so that the operation of the piston plate 41 is performed once. By this, it can be said that all the air in the reservoir 10, the interior space 11 is discharged.

However, when the size of the air treatment space 20 is limited for the purpose of using the space, the low temperature dry air and the existing air of the inner space 11 that are pushed out of the air treatment space 20 may form a layer. Convection can occur, which can reduce efficiency slightly. That is, since the existing high temperature and high humidity air coexists with the newly injected low temperature dry air, the duration until reaching the condition where condensation may occur is relatively shortened.

In this case, the above-described operation may be repeated one or more times in succession to discharge all the existing high temperature and high humidity air in the internal space 11, which is the volume of the internal space 11 and the air treatment space of the storage 10. (20) Humidity and temperature sensors (15, 16) can be controlled numerically depending on the ratio of the volume of the lower chamber (23b) of the processing chamber (23) or to sense the humidity and temperature of the interior space (11). You can also control with).

That is, by repeatedly performing the above-described air treatment and injection until the humidity of the interior space 11 of the storage 10 corresponds to the basic data stored in the central control unit, the high temperature and high humidity air of the interior space 11 is gradually phased. It discharges and stops operation by the signal input from the humidity sensor 15 when the desired humidity is reached.

On the other hand, considering the amount of air and the amount of moisture in the interior space (11) of the reservoir 10, the amount of energy required to increase their temperature to lower the relative humidity and to lift and discharge them by the injection of low-temperature dry air As a result of the calculation, it can be seen that lifting and discharging them is much more economical and saves energy.

And heat may be generated by the operation of the air treatment device 30, such heat may be released to the outside, but in order to use the more effective energy to store the heat generated in the air treatment device 30 of the storage 10 It may be more preferable to use to increase the temperature of the internal air to the inner space (11).

9 schematically shows a modification of the above-described first embodiment. This is in the configuration of the first embodiment described above, the dry air injection device 60 is provided in the outside air suction pipe 61 and the outside air suction pipe 61 which communicates the processing chamber 23 of the air treatment space 20 with the outside. Blowing fan 62 for injecting outside air into the processing chamber 23 of the air treatment space 20, and the opening and closing means for opening and closing the inner end of the outside air suction pipe (61). Here, the outside air suction pipe 61 is used as the outside air suction pipe 27 for inducing the outside air to the process chamber 23 in the first embodiment described above.

In addition, the opening and closing means may be configured in various forms. For example, the outside air suction pipe 61 is disposed on the processing chamber 23 side of the insulating partition 22 that divides the air treatment space 20 into the processing chamber 23 and the machine room 24. Hinges connected to the upper end of the check valve plate 63 larger than the diameter of the) may normally be configured to close by its own weight and open only when the outside air is sucked.

An embodiment of this configuration converts the air in the air treatment space 20 into a desired low temperature dry air by the air treatment device 30, and then stores the low temperature dry air through the dry air injection slot 25. When it is to be introduced into the inner space 11 of the air, the blower fan 62 is driven to inject the outside air into the processing chamber 23 of the air treatment space 20, thereby storing the low temperature dry air in the processing chamber 23 into the reservoir 10. Will be injected.

That is, when the blower fan 62 is driven to inject external air into the processing chamber 23 of the air treatment space 20, the check valve plate 63 is opened by the injection pressure of the outside air, thereby causing the processing chamber 23 to be opened. Injected into the top of the Then, the relatively high temperature outside air is filled from the upper side of the processing chamber 23, so that the pressure in the processing chamber 23 is increased, whereby the low-temperature dry air in the processing chamber 23 is pushed down, thereby The check valve plate 26 is opened through the dry air injection slot 25 and is injected into the inner space 11 of the reservoir 10, and at the same time, the processing chamber 23 is also filled with outside air.

Here, if the operation time of the blowing fan 62 is controlled by calculating the size of the processing chamber 23 of the air treatment space 20 and the amount of injected air of the blowing fan 62, only the low temperature dry air in the processing chamber 23 is stored ( 10) It can be pushed inside.

This modification can simplify the structure compared to the first embodiment described above, and since the piston plate 41 is not provided, the entire processing chamber 23 of the air treatment space 20 can be utilized, so that a larger amount of the gas can be used at a time. Dry air can be injected.

10 and 11 schematically show a second embodiment of the reservoir condensation prevention system according to the present invention.

This second embodiment has the upper chamber 23a of the processing chamber 23 on the upper and lower portions of the heat insulating wall 21, instead of removing the exhaust means 50 and the outside air suction pipe 27 in the configuration of the first embodiment described above. ) And a check valve plate (25a, 25b) for communicating the lower chamber (23b) and the internal space (11) of the reservoir (10), respectively, and opening and closing each of the ventilation slots (25a, 25b) ( 26a) and 26b are installed in the heat insulating wall 21 to convert the internal air of the reservoir 10 into low temperature dry air.

The upper check valve plate 26a is installed at the processing chamber 23 side of the heat insulating wall 21, and the lower check valve plate 26b is installed at the inner space 11 side of the storage 10 of the heat insulating wall 21.

As a result, in the above-described second embodiment, in the first embodiment described above, the exhaust means 50 for discharging the hot and humid air in the storage space 10, the internal space 11, out of the internal space 11 is provided with an air treatment space ( 20) It can be said that it is substantially the same as installing in the upper part of the heat insulation wall 21 so that it may communicate with the upper chamber 23a of the process chamber 23. FIG.

The second embodiment of this configuration, after converting the air in the lower chamber 23b of the processing chamber 23 of the air treatment space 20 with the air treatment apparatus 30 to low-temperature dry air, the dry air injection device 40 When the piston plate 41 is lowered, the first check valve 43 provided on the piston plate 41 is closed, so that the low temperature dry air in the lower chamber 23b is lower chamber 23b. As the pressure increases due to the decrease in volume, the lower check valve plate 26b is pushed through the lower vent slot 25b to the bottom of the inner space 11 of the reservoir 10.

Accordingly, the upper chamber 23a of the processing chamber 23 has a low pressure due to volume increase and a density difference with the low temperature dry air into which the high temperature and high humidity air in the interior space 11 of the reservoir 10 is injected. As the pressure rises while rising upward, the hot and humid air rising upward opens the upper check valve plate 26a through the upper ventilation slot 25a and is pushed out into the upper chamber 23a of the processing chamber 23. .

At this time, the amount of low-temperature dry air injected into the interior space 11 of the reservoir 10 and the amount of high temperature and high humidity air discharged from the interior space 11 to the upper chamber 23a of the processing chamber 23 are the same.

When the lowering of the piston plate 41 stops, the upper and lower chambers 23a and 23b of the processing chamber 23 and the interior space 11 of the reservoir 10 form a pressure balance, and thus the upper and lower check valve plates ( 26a) and 26b are rotated downward by their own weight to close the upper and lower ventilation slots 25a and 25b again.

On the other hand, when the piston plate 41 is raised to the initial position after the injection of the low temperature dry air is completed, the first check valve 43 installed in the piston plate 41 opens to open the high temperature and humid air in the upper chamber 23a. Is moved to the lower chamber 23b through the first check valve 43, so that the upper chamber 23a and the lower chamber 23b of the processing chamber 23 of the air treatment space 20 are stored in the storage room 10. It is filled with hot and humid air discharged from).

Such a process is intermittently performed one or several times depending on the detection result of the humidity and temperature sensors 15 and 16 installed in the interior space 11, thereby causing condensation to occur in the storage space 10. Keep dry.

Meanwhile, FIGS. 12 to 17 illustrate a third embodiment of the storage condensation preventing system according to the present invention, which injects light high temperature dry air into the internal space 11 of the storage room 10 so that relatively high temperature and high humidity air is provided. It is a configuration to discharge.

This third embodiment is substantially the same as the configuration of the above-described first embodiment except for a part of the configuration, for convenience the same reference numerals for the same configuration and will not be repeated description. In addition, the expression of the air inside the reservoir 10 as high temperature and high humidity in the following is relatively low temperature and high humidity compared to the high temperature dry air injected from the air treatment space 20. When using dry air, it is known in advance that the air is the same condition as the air represented by hot and humid air.

In this embodiment, in the configuration of the first embodiment described above, the dry air injection slot 25 and the check valve plate 26 for injecting the dry air into the storage 10 are toward the processing chamber 23 of the heat insulation wall 21. It is formed on the upper portion, the piston plate 41 of the dry air injector 40 is located at the lower portion of the processing chamber 23 of the air treatment space 20 at an appropriate interval with the bottom, accordingly, the air intake pipe 27 also It is provided to communicate with the narrow lower chamber 23b of the process chamber 23 partitioned by the piston plate 41.

The outside air suction pipe 27 is effectively installed near the upper end of the side wall 14 of the reservoir 10, and has a shape that is bent in a substantially refracted shape to connect to the lower chamber 23b of the processing chamber 23.

In the air treatment apparatus 30 of the first embodiment described above, as shown in FIG. 15, the blower 33 is connected to the lower side of the upper chamber 23a of the treatment chamber 23, and is accommodated in the cooling housing 31. The dehumidification unit 32 is composed of only the lower drain chamber 34 and the condensation pipe 36, and passes through the dehumidification unit 32 instead of the upper condensation chamber 35 while cooling and removing water, salt, and the like. Heating unit 70 for heating to a predetermined temperature is installed.

The heating unit 70 is installed at the outer upper end of the cooling housing 31 and connected to the upper end of the condensation pipe 36 of the dehumidification unit 32, and is installed inside the heating chamber 71. Hot wire 72 for heating the cooled and dehumidified air, and a heat insulating plate 73 provided at the bottom in the heating chamber 71 to prevent the heat emitted from the hot wire 72 from being transferred to the condensation pipe 36. )

The filter 75 for removing foreign matters in the air is discharged to the upper outlet (23a) of the processing chamber 23 of the air treatment space 20, the upper portion of the heating chamber 71 of the heating unit 70 ) Is detachably installed.

On the other hand, the piston plate 41 of the dry air injector 40 is opened only when the piston plate 41 is lowered, allowing only air in the lower chamber 23b to move to the upper chamber 23a, and rising. When the second check valve 80 is closed is installed.

The second check valve 80 is substantially the same as the exhaust means 50 without the protective roof 55. That is, a cylindrical valve body 81 having a support jaw 82 at its lower end, a lightweight valve plate 84 mounted on the support jaw 82 to shield the valve hole 83, and the valve plate 84. It consists of a mesh-shaped protective film 85 which is installed at the inner circumference of the valve body 81 at intervals above.

And the exhaust means 50 is installed on the side wall 14 of the reservoir 10 so that the low-temperature and humid air of the inner space 11 of the reservoir 10 pushed down by the high temperature dry air can be discharged out, it is smooth In order to secure the operation, it is provided with a connecting pipe 56 fitted horizontally in the exhaust hole 13, or may be installed in the connecting pipe 56 or bend upward by extending the valve body 51.

According to the third embodiment of this configuration, when it is determined that the air in the storage space 10 and the internal space 11 should be discharged by the detection signal of the humidity sensor 15, the air treatment device 30 first starts the air treatment space. (20) The air in the upper chamber 23a of the processing chamber 23 is sequentially passed through the dehumidifying unit 32 and the heating unit 70 accommodated in the cooling housing 31 to be heated to a predetermined temperature with dehumidification and dried at high temperature. Convert to state

At this time, the temperature of the heated air is heated higher than the temperature of the interior space 11 of the storage 10 detected by the temperature sensor 16, which is a temperature sensor 29 for sensing the temperature of the air treatment space 20 Controlled by

After the air in the processing chamber 23 is converted to the desired humidity and temperature, the forward and reverse drive motor 44 of the dry air injector 40 is driven to raise the piston plate 41, at which time the second check valve 80 Is pressed by the high temperature dry air of the upper chamber 23a, and the valve plate 84 closes the valve hole 83 of the valve body 81.

Therefore, the high temperature dry air in the upper chamber 23a of the processing chamber 23 is increased in pressure due to the volume decrease by the piston plate 41, so that the check valve is provided through the dry air injection slot 25 on the upper side of the insulation wall 21. Opening the plate 26 is pushed into the inner space 11 of the reservoir (10).

At this time, the lower chamber 23b of the processing chamber 23 has a lower pressure than atmospheric pressure due to an increase in volume due to the rise of the piston plate 41, so that the outside air flows through the outside air suction pipe 27 to the processing chamber 23. Is sucked into the lower chamber 23b.

On the other hand, the high temperature dry air injected into the internal space 11 is less dense than conventional air because the temperature is high and the humidity is low compared to the low temperature and high humidity air that was previously in the storage 10.

Therefore, the injected high temperature dry air floats above the existing low temperature and humid air in the storage space 10 of the storage space 10 by buoyancy, but the internal space 11 is sealed by the high temperature drying air which is continuously injected. The low temperature and high humidity air is also pressurized and eventually discharged out through the exhaust means 50 installed at the lower side of the side wall 14.

When the piston plate 41 rises to the top dead center and stops, pressure is balanced between the upper chamber 23a of the processing chamber 23 and the inner space 11 so that the check valve plate 26 is rotated downward by its own weight and dried. The air injection slot 25 is shielded, and the lower chamber 23b of the processing chamber 23 is filled with fresh air.

Thereafter, the forward and reverse drive motor 44 is rotated in the opposite direction so that the piston plate 41 is lowered to its initial position by its own weight. In this case, the valve plate 84 of the second check valve 80 installed on the piston plate 41 is stopped. ) Rises under pressure to open the valve hole 83.

Therefore, since the air in the lower chamber 23b of the processing chamber 23 moves to the upper chamber 23a through the open second check valve 80, both the upper and lower chambers 23a and 23b of the processing chamber 23 are used. Pressure change due to volume change does not occur, and only the piston plate 41 is moved.

After the completion of the lowering of the piston plate 41, depending on the amount of the high-temperature dry air injected and the humidity of the interior space 11 of the reservoir 10, or the like or the above-described operation is repeatedly performed several times.

18 and 19 schematically show a fourth embodiment of the reservoir condensation prevention system according to the present invention.

In this fourth embodiment, in the configuration of the above-described third embodiment, instead of removing the exhaust means 50 and the outside air suction pipe 27 in the configuration of the above-described second embodiment, the process chamber is provided on the upper and lower portions of the heat insulating wall 21. Ventilation slots 25a and 25b for communicating the upper chamber 23a and the lower chamber 23b of the 23 with the internal space 11 of the reservoir 10 are formed, respectively, and each of the ventilation slots 25a and 25b. The check valve plate (26a) (26b) for opening and closing the) is installed in the heat insulating wall (21) to convert the internal air of the reservoir (10) into high temperature dry air.

However, in contrast to the second embodiment, the upper check valve plate 26a is installed in the storage space 10 of the heat insulating wall 21, and the lower check valve plate 26b is disposed on the insulating wall 21. It is installed in the processing chamber 23 side.

As a result, in the fourth embodiment, the exhaust means 50 for discharging the hot and humid air in the storage space 10, the internal space 11, out of the internal space 11 may be provided. 20) It can be said that it is substantially the same as installing in the lower part of the heat insulation wall 21 so that it may communicate with the lower chamber 23b of the process chamber 23. FIG.

In the fourth embodiment of this configuration, after converting the air in the upper chamber 23a of the processing chamber 23 of the air treatment space 20 with the air treatment apparatus 30 to the high temperature dry air, the forward and reverse driving motor 44 When the piston plate 41 rises, the second check valve 80 provided in the piston plate 41 is closed, so that the high temperature dry air in the upper chamber 23a reduces the volume of the upper chamber 23a. As the pressure increases, the upper check valve plate 26a is opened through the upper vent slot 25a, and the upper check valve plate 26a is pushed into the upper part of the storage space 10.

Accordingly, the lower chamber 23b of the processing chamber 23 is formed with a low pressure due to the volume increase and is subjected to the pressure by the high temperature dry air into which the low temperature and high humidity air in the interior space 11 of the reservoir 10 is injected. The lower check valve plate 26b is opened through the lower vent slot 25b and pushed out to the lower chamber 23b of the processing chamber 23.

When the lowering of the piston plate 41 stops, the upper and lower chambers 23a and 23b of the processing chamber 23 and the inner space 11 of the reservoir 10 are in pressure balance, and the upper and lower check valve plates 26a are provided. ) 26b is rotated by its own weight to close the upper and lower ventilation slots 25a and 25b again.

On the other hand, when the piston plate 41 is lowered to the initial position after the injection of the high temperature dry air is completed, the second check valve 80 installed in the piston plate 41 is opened to cool the low temperature and humid air of the lower chamber 23b. Is moved to the upper chamber 23a through the second check valve 80, so that the upper chamber 23a and the lower chamber 23b of the processing chamber 23 of the air treatment space 20 are stored in the storage 10 and the inner space 11. It is filled with low temperature and humidity air discharged from).

20 and 21 schematically illustrate a fifth embodiment of the storage condensation preventing system according to the present invention.

This embodiment has a closed interior space (11) has a reservoir (10) covered all over the door except for the door (17), and installed in the cover (E) covering the reservoir (10) and high temperature and humidity The air treatment passage 90 which cools and dehumidifies the external air as it cools and dehumidifies, the blower 100 which injects the external air into the air treatment passage 90, and the air treatment which opens and closes the air treatment passage 90. And exhaust means (50) for discharging the hot and humid inside of the reservoir (10) out of the reservoir (10) by the density difference between the passage opening and closing means and the low temperature dry air injected from the air treatment passage (90). It is composed.

The ceiling 12 of the reservoir 10 senses the humidity and temperature of the internal space 11 and sends it to a central controller (not shown) to operate the blower 100 and the air treatment apparatus 30 described later. The humidity sensor 15 and the temperature sensor 16 for controlling are provided.

The air treatment passage 90 is preferably constituted by continuous metal pipes such as copper pipes having excellent thermal conductivity in a zigzag form along the vertical direction, and the ends thereof are connected to the inner space 11 of the reservoir 10. The air treatment passage 90 is formed by, for example, connecting the metal pipes 91 in a straight line to an elbow socket 92 having a substantially U-shape at its bent portion.

At this time, the metal pipes 91 are preferably inclined at an appropriate angle α with respect to the horizontal for easy drainage of the condensed water generated by condensation of water vapor contained in the outside air.

The internal space of the air treatment passage 90 needs to be sufficiently large in order to have a function similar to that of the air treatment space 20 in the above-described embodiments.

In the vicinity of the end (lower end) of the air treatment passage 90, a drain pipe 93 for discharging the condensed water is branched, and the drain pipe 93 is interrupted by a drain valve 94. Although not shown, the drain valve 94 may be controlled by a level sensor that detects a water level in the drain pipe 93.

The blower 100 is installed at the inlet of the air treatment passage 90, and the air treatment passage opening and closing means is connected to the inside of the side wall 14 of the reservoir 10 by a hinge, although not separately illustrated, and thus the air treatment passage 90. It may be composed of a check valve plate to close the end of and open only by the injection pressure of the outside air injected by the blower 100.

Exhaust means 50 is installed in the exhaust hole 13 provided in the ceiling 12 of the reservoir 10, and has the same configuration and operation as the exhaust means 50 of the above-described embodiments, for convenience, description will be duplicated Omit.

In the fifth embodiment configured as described above, when it is determined that the air in the storage 10 should be discharged by the detection signals of the humidity sensor 15 and the temperature sensor 16, the blower 100 is driven to process the outside air. Inject into passageway 90. Then, a high pressure is generated in the air treatment passage 90 so that the air inside the first air is injected into the storage 10 while opening and closing the opening and closing means, and then the outside air injected by the blower 100 is air treatment passage. As it passes through (90), it is properly cooled and dehumidified and then continuously injected.

At this time, the air injected into the inside of the reservoir 10 is in the air treatment passage 90 buried in the cover portion E, which is significantly lower in temperature than the outside, while being dehumidified and cooled, and is in a low temperature drying state, and the blower 100 The outside air injected by) is heat exchanged in the course of passing through the cold air treatment passage (90), and the water vapor contained therein is cooled and converted to a low temperature dry state.

Therefore, the low temperature dry air injected into the cellar 10 is heavier than the existing high temperature and high humidity air in the cellar 10 and is located at the bottom of the cellar 10, and the existing high temperature and high humidity air is injected into the low temperature dry air. Due to the difference in density, the pressure of the reservoir 10 is increased while floating upward.

When the pressure of the reservoir 10 is increased in this way, the exhaust means 50 is opened, and the existing high temperature and high humidity air pushed up by the injected low temperature dry air escapes to the outside, and the inside of the reservoir 10 Filling with freshly injected low-temperature dry air can prevent condensation.

Here, if the operation time of the blower 100 is controlled by calculating the volume of the air treatment passage 90 and the amount of injected air of the blower 100, only the low temperature dry air in the air treatment passage 90 is stored in the storage 10. Not only can it be pushed, but also it can push out all the hot and humid air in the reservoir (10).

On the other hand, it is possible to change the inside of the reservoir 10 to low-temperature dry air without condensation with only such a configuration, but more preferably, further provided with an air treatment device 30 to pass through the air treatment passage 90 The outside air can be reprocessed to the desired humidity and temperature and then injected.

To this end, the air treatment device 30 is embedded in the cover portion E, and is connected to the inlet end and the distal end of the air treatment passage 90 through the three-way valve 110, respectively, and at the end of the air treatment passage 90 thereof. Humidity sensor 120 and the temperature sensor 130 for sensing the humidity and temperature of the outside air passed through and sent to the central control unit is installed.

In this case, the air treatment passage opening and closing means may be replaced by one of the two three-way valves 110 without being separately installed. In addition, since the air treatment device 30 has the same configuration and operation as the air treatment device 30 of the first embodiment, the overlapping description is omitted.

When the air treatment device 30 is provided as described above, the humidity sensor 120 and the temperature sensor of the outside air injected by the blower 100 and passed through the air treatment passage 90 are installed at the end thereof. The sensing unit 130 senses the data and sends it to the central control unit. The central processing unit compares the input data with the stored basic data and injects the air processing unit 30 without operating it when it matches the set humidity and temperature.

However, when the humidity and temperature is less than the comparison result, after the inlet and the end of the air treatment passage 90 through the two three-way valve 110 to form a closed circuit and the air treatment device 30, the air treatment device (30) is operated to dehumidify and cool again until the set conditions are reached while circulating the air in the air treatment passage (90). At this time, the humidity and temperature of the outside air is also sent to the central control unit by the humidity sensor 120 and the temperature sensor 130 installed in the air treatment passage (90).

If the air conditioner 30 meets the setting conditions, the blower 100 and the air treatment passage 90 and the reservoir 10 are communicated again through the three-way valve 110, and the blower 100 is operated to operate the outside air. Is injected into the air treatment passageway 90 to inject the low temperature dry air in the air treatment passageway 90 into the reservoir 10.

By repeating this operation several times, the inside of the storage 10 can be completely filled with low temperature dry air.

On the other hand, in the interior space 11 of the reservoir 10, for example, loads such as ammunition are stored and stored, so that the door 17 must be opened for entry and exit of the load. Only waste will result.

Therefore, it is preferable to include a door opening and closing sensor 140 for stopping the operation of the system by detecting the opening of the door 17 of the storage 10 and sending it to the central control unit.

The door opening and closing sensor 140 is applied not only to the fifth embodiment but also to the above-described first to fourth embodiments.

In the above description, the air treatment device is limited to a specific configuration, but the present invention is not limited thereto. For example, an existing dehumidifier, a refrigerator or a freezer, a constant temperature and humidity device, or the like may be used individually or in a combination thereof. Of course it can.

In addition, the storage condensation prevention system according to the present invention is particularly suitable for applying to the ammunition, it can be simply installed and used in the existing ammunition as well as newly constructed ammunition.

As described above, according to the condensation prevention system of the present invention, the condensation problem occurring in the use of the existing ammunition and document storage, etc. by using a separate air treatment space and an air treatment apparatus, Only air can be discharged easily and reliably by buoyancy caused by density difference between air according to the temperature. Therefore, the condensation problem of the reservoir can be effectively and economically saved with much less energy than the energy required to raise the temperature inside the reservoir. It can be solved.

Moreover, once the dry air is introduced, the pressure-driven check valve ensures that the outside air is introduced again and moisture is generated, and the seal of the reservoir is automatically maintained. The system can be shut down for a long time. The burden of maintenance costs due to frequent operation can be minimized.

In addition, because only the air inside the reservoir is controlled and dehumidified, more loads can be stored in the same volume of reservoirs, while condensation can be economically prevented, especially if there are many reservoirs. It is less effective because it is smaller and more economical. It is therefore particularly suitable for applications in ammunition where serious condensation occurs and requires a large amount of storage.
