Description

  The present invention relates to a humidity control apparatus that performs humidity control using a hygroscopic liquid such as lithium chloride (LiCl).

  Conventionally, for example, humidity control apparatuses that perform humidity control using a hygroscopic liquid such as lithium chloride have been known. The higher the solution concentration and the lower the temperature, the lower the saturated vapor pressure of the hygroscopic liquid, and the easier it is to absorb moisture. Conversely, the hygroscopic liquid has a lower saturated solution pressure and a higher temperature, the saturated vapor pressure becomes higher, and moisture is more easily desorbed. The humidity control apparatus performs humidity control processing by adjusting the saturated vapor pressure of the hygroscopic liquid using this property.

  The humidity control apparatus described in Patent Document 1 takes in air from a humidity control space or the outside, and brings the taken-in air into contact with the hygroscopic liquid, thereby dehumidifying or humidifying the taken-in air into the humidity control space. It has an indoor unit that performs the process of returning. The indoor unit has a heat exchanger on a pipe line that supplies the hygroscopic liquid, heats or cools the hygroscopic liquid in the heat exchanger, and injects the heated or cooled hygroscopic liquid from the injection nozzle onto the filler. Was.

  In such a humidity control apparatus, it is required to increase the energy use efficiency. Here, the energy use efficiency is the ratio of the amount of air that can be dehumidified or humidified with respect to the total energy applied to the humidity control apparatus.

  In view of this, the present applicant has proposed a humidity control device with improved energy use efficiency (Japanese Patent Application No. 2008-145812). This humidity control device is a humidity control device that adjusts the humidity of a humidity control space, and includes a housing having an intake port for taking in air and an exhaust port for discharging air after humidity control processing to the humidity control space, A hygroscopic liquid supply unit that supplies hygroscopic liquid that exchanges moisture between the hygroscopic liquid, and temporarily stores the hygroscopic liquid to allow air to pass through the hygroscopic liquid supplied from the hygroscopic liquid supply unit And a heat exchange coil for heating or cooling the air and the hygroscopic liquid.

  With this configuration, moisture between the hygroscopic liquid and the air is obtained by temporarily retaining the hygroscopic liquid in the heat exchange coil and passing the air through the hygroscopic liquid while heating or cooling the heat exchange coil. Can be efficiently exchanged and energy use efficiency can be improved. This is presumably because the amount of saturated water vapor in the air changes due to the configuration in which not only the hygroscopic liquid but also the air is heated or cooled by the heat exchange coil, so that moisture is easily exchanged with the hygroscopic liquid.

  Based on this proposal, the present inventors have found that the following problem occurs when the member for retaining the hygroscopic liquid is changed from a conventional filler to a heat exchange coil. That is, since the heat exchange coil is not hydrophilic, the hygroscopic liquid dropped from the hygroscopic liquid supply section flows down through the heat exchange coil at a higher speed than in the case of the filler. For this reason, splashes are generated when the hygroscopic liquid hits the surface of the hygroscopic liquid accumulated in the liquid tank, and minute particles of the hygroscopic liquid are scattered inside the humidity control apparatus. In addition, fine particles of the hygroscopic liquid are also generated in the vicinity of the exchange coil. Such fine particles are discharged from the exhaust port of the humidity control device into the humidity control space (inside the room) along the flow of the humidity-controlled air.

  Here, in order to prevent the fine particles of the hygroscopic liquid from being discharged from the humidity control apparatus to the humidity control space, it is conceivable to provide a filter or the like at the exhaust port to prevent the discharge of the fine particles. However, when the particle diameter of the fine particles is smaller than 1 μm, for example, about 0.5 μm, the fine particles pass through the filter, and the discharge of the fine particles to the humidity control space cannot be effectively prevented.

  Therefore, the present invention is intended to reduce scattering of fine particles of the hygroscopic liquid in the humidity control apparatus having a heat exchange coil for temporarily retaining the hygroscopic liquid and heating or cooling the air and the hygroscopic liquid. Objective.

  The humidity control apparatus of the present invention is a humidity control apparatus that adjusts the humidity of the humidity control space, and includes a housing having an intake port for taking in air and an exhaust port for discharging the air after humidity control processing to the humidity control space; A hygroscopic liquid supply unit that supplies hygroscopic liquid that exchanges moisture with air, and a hygroscopic liquid that is supplied from the hygroscopic liquid supply unit to temporarily contact the air with the hygroscopic liquid A heat exchange coil that heats or cools the air and the hygroscopic liquid, a liquid tank that is supplied from the hygroscopic liquid supply unit and that contains the hygroscopic liquid that has passed through the heat exchange coil, and the heat exchange coil. The absorbent is disposed so that the hygroscopic liquid once supplied is absorbed and the exuded hygroscopic liquid falls into the liquid tank.

  According to this configuration, the hygroscopic liquid enters the liquid tank with its falling speed being reduced by being absorbed by the absorbent material. Therefore, the hygroscopic liquid entering the liquid tank is stored in the liquid tank. It is possible to reduce the occurrence of splashes when colliding with the surface, and to reduce the scattering of fine particles of the hygroscopic liquid due to the occurrence of the splashes.

  In the humidity control apparatus, the absorbent material is provided corresponding to an air ventilation surface of the heat exchange coil.

  With this configuration, the fine particles of the hygroscopic liquid generated on the air ventilation surface of the heat exchange coil can be reduced by air, or the spray of hygroscopic liquid can be generated on the air ventilation surface of the heat exchange coil. Can be reduced. In addition, a humidity control device using a hygroscopic liquid has a dust removal effect due to contact with gas and liquid, and also has a bacteria removal effect when using a humidity control agent having a sterilization ability such as lithium chloride. By disposing the absorbent material on the air ventilation surface, an effect of enhancing the dust removing effect and the sterilizing effect can be obtained.

  In the humidity control apparatus, the absorbent material is provided below the heat exchange coil, and the hygroscopic liquid that has fallen from the heat exchange coil passes through the absorbent material and then enters the liquid tank.

  With this configuration, it is possible to prevent the hygroscopic liquid that has flowed through the heat exchange coil at a high speed from entering the liquid tank as it is. Since the hygroscopic liquid is absorbed by the absorbent before entering the liquid tank, the speed is reduced before entering the liquid tank and enters the liquid tank, so the hygroscopic liquid accumulated in the liquid tank The occurrence of splashes can be reduced.

  Moreover, in said humidity control apparatus, the said absorber and the said heat exchange coil are closely_contact | adhered. With this configuration, it is possible to reduce splashes generated by the collision of the hygroscopic liquid that has fallen from the heat exchange coil with the hygroscopic liquid that has penetrated the absorbent material on the surface of the absorbent material.

  Further, in the humidity control apparatus, the hygroscopic liquid supply unit supplies the hygroscopic liquid from above the heat exchange coil, and the intake port is provided between the absorber and the liquid tank. Provided on the side of the body, the absorbent material has air permeability, and supplies air taken in through the intake port from below the heat exchange coil through the absorbent material.

  With this configuration, air to be dehumidified or humidified flows in a direction opposite to the direction in which the hygroscopic liquid flows (counter direction), so that the contact between the air and the hygroscopic liquid increases, and the effect of dehumidification or humidification is improved. .

  Further, in the humidity control apparatus, the hygroscopic liquid supply unit supplies the hygroscopic liquid from above the heat exchange coil, and the intake port is provided on a side of the heat exchange coil, and the absorption The material is provided on the side of the heat exchange coil opposite to the air inlet, and supplies air taken in through the air inlet from the side of the heat exchange coil.

  With this configuration, when the air to be dehumidified or humidified flows in the direction crossing the direction in which the hygroscopic liquid flows (cross direction), the hygroscopic liquid blown in the lateral direction by the wind of the air is absorbed by the absorbent material, It is possible to reduce the splashes generated by the blown-off hygroscopic liquid and the splashes generated by the blown-off hygroscopic liquid directly falling on the liquid surface of the hygroscopic liquid stored in the liquid tank.

  In the humidity control apparatus, the absorbent material and the heat exchange coil are in close contact with each other. According to this configuration, the hygroscopic liquid that has jumped out from the side of the heat exchange coil can be reliably received and absorbed by the absorbent material, and splashes generated by jumping out from the side surface of the heat exchange coil can be eliminated.

  In the humidity control apparatus, the absorbent material has air permeability, and is also provided between the heat exchange coil and the intake port, and the air taken in through the intake port is converted into the heat exchange coil and the intake air. It supplies from the side of the said heat exchange coil through the said absorption material between opening | mouths. According to this structure, the hygroscopic liquid which jumps out from the side surface of the heat exchange coil and falls directly into the liquid tank can be reduced more reliably.

  In the humidity control apparatus described above, the absorbent material has a thickness of 1 to 300 mm. When the absorbent material is 1 mm or more, a sufficient hygroscopic liquid holding function by the absorbent material can be secured and an action as a buffer material can be obtained. If the absorbent material is 300 mm or less, pressure loss can be suppressed.

  In the humidity control apparatus, the absorbent is provided inside the heat exchange coil, and the hygroscopic liquid supplied from the hygroscopic liquid supply unit is absorbed by the absorbent, thereby the thermal coil. Temporarily stays inside.

  With this configuration, the speed of the hygroscopic liquid flowing in the heat exchange coil can be reduced. Thereby, the speed | rate of the hygroscopic liquid which enters into a liquid tank can be slowed, and generation | occurrence | production of splash can be reduced. In addition, the residence time of the hygroscopic liquid in the heat exchange coil can be increased, and the energy utilization efficiency can be increased.

  In the humidity control apparatus, the absorbent material is a porous sponge or a woven fabric. With this configuration, the absorbent material can sufficiently absorb the hygroscopic liquid, and the absorbent material can act as a buffering material, and can reduce splashes generated when the hygroscopic liquid collides with the absorbent material.

  According to the present invention, the hygroscopic liquid is temporarily retained in the heat exchange coil, and while the heat exchange coil is heated or cooled, the hygroscopic liquid is brought into contact with air, and the hygroscopic liquid is absorbed by the absorbent. Since the falling speed is reduced, energy use efficiency can be improved and scattering of the hygroscopic liquid can be reduced.

Hereinafter, a humidity control apparatus according to an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram illustrating a configuration of a humidity control apparatus 1 according to the first embodiment. The humidity control device 1 takes in air in a humidity control space (indoor) and makes the humidity adjustment by bringing the taken-in air into contact with the hygroscopic liquid L, and is used for humidity control in the processor 10. A regenerator 30 for regenerating the hygroscopic liquid L. Here, the regeneration of the hygroscopic liquid L refers to returning the concentration of the hygroscopic liquid L whose concentration has been changed by performing humidity adjustment to a state before being used for humidity adjustment. For example, in the case of dehumidification, moisture in the air is absorbed by the hygroscopic liquid L by cooling the hygroscopic liquid L having a high solution concentration and bringing the cooled hygroscopic liquid L into contact with air. Since moisture is absorbed by the hygroscopic liquid L by this treatment, the solution concentration of the hygroscopic liquid L is lowered. Since the hygroscopic liquid L having a low solution concentration cannot perform sufficient dehumidification, the moisture is desorbed from the hygroscopic liquid L to return to the hygroscopic liquid L having a high solution concentration. In the case of humidification, on the contrary, the solution concentration of the hygroscopic liquid L becomes high, so that the hygroscopic liquid L is returned to the hygroscopic liquid L having a low solution concentration by absorbing moisture.

  In the present embodiment, lithium chloride (LiCl) is used as the hygroscopic liquid L. The hygroscopic liquid is not limited to lithium chloride, but a salt solution having a deliquescent property such as saline, a polyhydric alcohol having a high hygroscopic property such as glycerin, ethylene glycol or propylene glycol, or other hygroscopic property. An inexpensive liquid may be used.

  The processor 10 is an indoor unit that regulates the humidity of indoor air, and the regenerator 30 is an outdoor unit that regenerates the hygroscopic liquid L by transferring moisture to and from the outside air. Although FIG. 1 shows an example in which one regenerator 30 is connected to one processor 10, a configuration in which one regenerator 30 is connected to a plurality of processors 10 may be adopted. For example, when the humidity control apparatus 1 is installed in an apartment house or a large supermarket, the processing machines 10 are installed in each room or floor, and one regenerator 30 connected to each processing machine 10 is installed outside. It can also be set as the aspect to do.

  The processor 10 and the regenerator 30 are connected by a first hygroscopic liquid conduit 50 and a second hygroscopic liquid conduit 51. The first hygroscopic liquid pipe 50 is a pipe for sending the hygroscopic liquid L from the processor 10 to the regenerator 30, and the second hygroscopic liquid pipe 51 is a hygroscopic pipe from the regenerator 30 to the processor 10. This is a conduit for feeding the sex liquid L. By using the first hygroscopic liquid conduit 50 and the second hygroscopic liquid conduit 51 to circulate the hygroscopic liquid L between the processor 10 and the regenerator 30, the moisture absorption used in the processor 10. The property liquid L can be regenerated by the regenerator 30 and returned to the processor 10.

  Next, the configuration of the processor 10 will be described. The processor 10 includes a housing 11 having an intake port 12 and an exhaust port 13. The exhaust port 13 has an exhaust fan 14 and forcibly exhausts the air in the housing 11. Further, by discharging air from the inside of the housing 11, the inside of the housing 11 becomes negative with respect to the outside, and the air outside the housing 11 is taken into the housing 11 through the air inlet 12.

  The housing 11 includes a hygroscopic liquid supply unit 15, a heat exchange coil 16, and a liquid tank 17. The hygroscopic liquid supply unit 15 has a plurality of nozzles for dropping the hygroscopic liquid L. The hygroscopic liquid L is supplied by dropping the hygroscopic liquid L from a plurality of nozzles.

  The heat exchange coil 16 temporarily retains the hygroscopic liquid L supplied from the hygroscopic liquid supply unit 15. Air taken from the air inlet 12 is supplied to the heat exchange coil 16 from below (in FIG. 1, arrows indicate the flow of air). Thereby, the hygroscopic liquid L supplied from the upper side and the air supplied from the lower side come into contact with each other in the heat exchange coil 16, and moisture is exchanged between the hygroscopic liquid L and the air. A corrosion resistant coating is applied to the surface of the heat exchange coil 16. Thereby, corrosion of the heat exchange coil 16 by the hygroscopic liquid L can be prevented, and the hygroscopic liquid L can be retained.

  The heat exchange coil 16 constitutes a heat exchanger of the heat pump 21. Here, the configuration of the heat pump 21 will be described. The heat pump 21 includes a heat exchange coil 16, a heat exchange coil 36, a compressor 22, an expansion valve 23, and a refrigerant pipe 24 that connects them. The heat pump 21 can cause the heat exchange coil 16 to function as an evaporator or a condenser by reversing the refrigerant flow. The heat exchange coil 36 performs the reverse process of the heat exchange coil 16.

  The heat exchange coil 16 temporarily retains the hygroscopic liquid L supplied from the hygroscopic liquid supply unit 15 and heats or cools the air that has temporarily retained the air passing through the heat exchange coil 16. To do. Whether the hygroscopic liquid L is heated or cooled depends on whether it is humidified or dehumidified by the processor 10. That is, when the processor 10 performs humidification, the moisture contained in the hygroscopic liquid L is desorbed and the hygroscopic liquid L and air are heated so as to be included in the air. Conversely, when the processor 10 performs dehumidification, the hygroscopic liquid L and the air are cooled in order to make the hygroscopic liquid L easily absorb moisture in the air.

  An absorbent material 27 is provided below the heat conversion coil 16 and above the liquid tank 17. The absorbent material 27 has hydrophilicity and air permeability. The absorbent material 27 is, for example, a porous sponge or a woven fabric.

  FIG. 2A is a perspective view showing the configuration of the heat exchange coil 16 and the absorbent material 27. FIG. 2B is a cross-sectional view for describing the inside of the heat exchange coil 16 and the configuration of the absorbent 27, and shows the heat transfer tube included in the heat exchange coil 16. In the relationship between FIG. 2A and FIG. 2B, the direction D1 shown in FIG. 2A corresponds to the direction D1 shown in FIG. 2B. Further, in FIG. 2B, the depth direction in the drawing corresponds to the direction D2 in FIG.

  As shown in FIG. 2A, the heat exchange coil 16 has a plurality of plate fins 61 arranged in parallel to each other. When the hygroscopic liquid L and air pass between the plate fins 61, heat exchange is performed between the hygroscopic liquid L and air and the plate fins 61. If the distance between the plate fins 61 is too narrow, the hygroscopic liquid L is clogged due to the surface tension of the hygroscopic liquid L. If the distance between the plate fins 61 is too wide, the contact area between the hygroscopic liquid L and air will be small. Accordingly, the distance between the plate fins 61 is determined in consideration of these factors. The interval between the plate fins 61 is preferably 3 to 10 mm, more preferably 4 to 8 mm, and most preferably 5 to 6 mm.

  The heat exchange coil 16 has a heat transfer tube 62 through which the refrigerant flowing from the compressor 22 or the expansion valve 23 flows. As shown in FIG. 2B, the heat transfer tube 62 extends through the plate fin 61. The temperature of the refrigerant flowing through the heat transfer tubes 62 moves to the plate fins 61. The heat transfer tube 62 has a plurality of straight tube portions 62a perpendicular to the plate fins 61, and the plurality of straight tube portions 62a are connected outside the plate fins 61 to form one flow path. In FIG. 2B, only one heat transfer tube 62 is illustrated, but actually, the heat transfer tube 62 has a plurality of stages in the depth direction of the paper surface (the left-right direction D2 of the paper surface in FIG. 2A).

  The heat exchange coil 16 has headers 63 and 64 connected to the refrigerant pipe 24 of the heat pump 21. Each of the end portions of the flow path of the heat transfer tube 62 is connected to the headers 63 and 64. The refrigerant supplied from the refrigerant pipe 24 to the header 63 flows through the heat transfer pipe 62, returns to the header 64, and returns from the header 64 to the refrigerant pipe 24. The heat pump 21 can reverse the flow of the refrigerant. In this case, the refrigerant is supplied to the header 64 and returns from the header 63 to the refrigerant pipe 24.

  The absorbent 27 has a size and shape that covers the entire bottom surface of the heat exchange coil 16. With this shape and arrangement of the absorbent material, the hygroscopic liquid L supplied from the hygroscopic liquid supply unit 15 and passed through the heat exchange coil 16 is absorbed by the absorbent material 27 before entering the liquid tank 17. At this time, the absorbing material 27 functions as a buffer material that absorbs the hygroscopic liquid L and weakens its speed. The absorbent 27 is disposed above the liquid tank 17, and the hygroscopic liquid L that has oozed out of the absorbent 27 falls into the liquid tank 17.

  The absorber 27 is provided above the air inlet 12. Specifically, the absorbent material 27 is disposed such that the upper surface thereof is above the upper end of the intake port 12. By arranging the absorber 27 in this way, the air taken in from the air inlet 12 passes through the absorber 27 and is supplied to the heat exchange coil 16. Thus, by arranging the absorbent 27 corresponding to the ventilation surface of the heat exchange coil 16, the absorbent 27 also has a function as a dust removal filter.

  If the distance L1 between the absorbent 27 and the heat exchange coil 16 is too long, the hygroscopic liquid L that has dropped from the heat exchange coil 16 at a high speed collides with the surface of the absorbent 27 and is held by the absorbent 27. Splashes may occur when the hygroscopic liquid L is repelled. Further, the absorbent liquid L may be splashed between the heat exchange coil 16 and the absorbent material 27. Therefore, the shorter the distance L1 between the absorbent 27 and the heat exchange coil 16, the better. Specifically, the distance L1 between the absorbent material 27 and the heat exchange coil 16 is preferably 0 to 10 mm, more preferably 0 to 5 mm, and most preferably the absorbent material 27 and the heat exchange coil 16. It is in close contact.

  If the thickness L2 of the absorbent material 27 is too thin, the function of the absorbent material 27 as a buffering material will be reduced, and the droplet velocity will be sufficient when receiving the hygroscopic liquid L falling from the heat exchange coil 16. Cannot be weakened, and when the hygroscopic liquid L collides with the absorbent 27, there is a risk of splashing. In addition, if the thickness L2 of the absorbent 27 is too thin, bubbles may be generated on the upper surface, which is the downstream surface of the air flow. On the other hand, if the absorbent 27 is too thick, the pressure loss increases. Therefore, the thickness of the absorbent material 27 is determined in consideration of these factors. As for the thickness of the absorber 27, 1-300 mm is preferable, More preferably, it is 50-100 mm.

  With reference to FIG. 1 again, the configuration of the processor 10 will be described. In the liquid tank 17, the absorbent liquid L that has oozed out from the absorbent 27 is dropped and stored. The processing machine 10 has a pipe 18 for supplying the hygroscopic liquid L in the liquid tank 17 to the hygroscopic liquid supply unit 12. A pump 19 is attached to the pipe 18 and sucks up the hygroscopic liquid L in the liquid tank 17.

  The first hygroscopic liquid pipe 50 for sending the hygroscopic liquid L in the liquid tank 17 to the regenerator 30 is connected to the pipe 18 for sucking the hygroscopic liquid L from the liquid tank 17 through the three-way valve 20. ing. The three-way valve 20 controls the amount of the hygroscopic liquid L sent to the hygroscopic liquid supply unit 15 of the processor 10 and the amount of the hygroscopic liquid L sent to the regenerator 30 through the first hygroscopic liquid conduit 50. That is, a part of the hygroscopic liquid L stored in the liquid tank 17 is pumped up by the pump 19 and flows to the pipe 18 for reuse, and a part of the hygroscopic liquid L flows to the first hygroscopic liquid pipe 50 by the pump 52. Played.

  Next, the playback device 30 will be described. The regenerator 30 includes a housing 31 having an intake port 32 and an exhaust port 33. The regenerator 30 has an exhaust fan 34 and forcibly exhausts the air in the housing 31. Further, by exhausting air from the inside of the casing 31, outside air is taken into the casing 31 through the intake port 32.

  In the housing 31, the hygroscopic liquid supply part 35 that supplies the hygroscopic liquid L, the heat exchange coil 36 that temporarily stores the hygroscopic liquid L, and the absorbent liquid L that has passed through the heat exchange coil 36 are contained. And a liquid tank 37 to be placed. The hygroscopic liquid supply unit 35 includes a first supply unit 35 a that supplies the hygroscopic liquid L sent from the processor 10, and a second supply unit 35 b that supplies the hygroscopic liquid L in the liquid tank 37. have. Each of the first supply unit 35a and the second supply unit 35b has a plurality of nozzles for dropping the hygroscopic liquid L. The heat exchange coil 36 has the same configuration as the heat exchange coil 16 included in the processor 10. The heat exchange coil 36 constitutes a heat exchanger of the heat pump 21 as described above.

  An absorbent material 47 is provided below the heat exchange coil 36. The absorbent material 47 has the same configuration as the absorbent material 27 of the processor 10, and the hygroscopic liquid L that has passed through the heat exchange coil 36 is once absorbed by the absorbent material 47. The absorbent material 47 is arranged above the liquid tank 37 so that the hygroscopic liquid L that has oozed out from the absorbent material 47 is dropped into the liquid tank 37.

  The regenerator 30 has a pipe 38 for supplying the hygroscopic liquid L in the liquid tank 37 to the second supply unit 35b. A pump 39 is attached to the pipe 38 to suck up the hygroscopic liquid L in the liquid tank 37. Further, a heating source 40 is attached to the tube 38 and heats the hygroscopic liquid L sucked up from the liquid tank 37. The second supply unit 35 b performs the regeneration process by dropping the hygroscopic liquid L sucked up from the liquid tank 37 and passing air through the hygroscopic liquid L in the heat exchange coil 36. By recirculating the hygroscopic liquid L in the liquid tank 37 using the pipe 38 in this way, the regenerator 30 repeatedly performs the regeneration process of the hygroscopic liquid L.

  Further, the regenerator 30 has a water supply pipe 41 for supplying water to the liquid tank 37. A valve 42 is provided on the water supply pipe 41, and water supply is controlled by the valve 42.

  A second hygroscopic liquid conduit 51 is connected to the liquid tank 37. The hygroscopic liquid L in the liquid tank 37 returns to the processor 10 through the second hygroscopic liquid pipe 51. The amount of the hygroscopic liquid L returning from the regenerator 30 to the processor 10 is adjusted by a valve 53. In the present embodiment, the valve 53 controls the amount of the hygroscopic liquid L that is returned to the processor 10 so that the liquid level of the hygroscopic liquid L in the liquid tank 37 is constant. Other configurations of the regenerator 30 are the same as those of the processor 10.

  The humidity control apparatus 1 includes a heat exchanger 54 that performs heat exchange between the first hygroscopic liquid conduit 50 and the second hygroscopic liquid conduit 51. The heat exchanger 54 contributes to reducing the recooling load in the processor 10 and the reheating load in the regenerator 30.

  Next, operation | movement of the humidity control apparatus 1 of this Embodiment is demonstrated. First, an outline of the operation of the humidity control apparatus 1 will be described. In the humidity control apparatus 1 of the present embodiment, the processor 10 takes in air or outside air in the humidity control space, and passes the taken-in air through the hygroscopic liquid L, so that moisture is absorbed between the air and the hygroscopic liquid L. Send and receive, adjust the humidity of the air, exhaust the conditioned air to the humidity control space. The hygroscopic liquid L used for humidity adjustment in the processor 10 is sent to the regenerator 30, and is regenerated to the original solution concentration by the regenerator 30.

  Hereinafter, the operation of the humidity control apparatus 1 will be described in detail using the dehumidifying process as an example. When dehumidification is performed by the humidity control apparatus 1, the heat pump 21 causes the heat exchange coil 16 to function as an evaporator and the heat exchange coil 36 as a condenser. A hygroscopic liquid L having a high solution concentration is placed in the liquid tank 17 of the processor 10.

  The processor 10 sucks the hygroscopic liquid L having a high solution concentration from the liquid tank 17 and supplies it to the hygroscopic liquid supply unit 15. In the hygroscopic liquid supply unit 15, the hygroscopic liquid L is dropped from a plurality of nozzles. The dropped hygroscopic liquid L temporarily stays in the heat exchange coil 16.

  At the same time as the above operation, the processor 10 operates the fan 14 to take in air from the air inlet 12 and supplies the taken air to the heat exchange coil 16 from below. The hygroscopic liquid L having a high solution concentration staying in the heat exchange coil 16 comes into contact with the air, and moisture in the air is absorbed by the hygroscopic liquid L. Further, since the heat exchange coil 16 functions as an evaporator, the hygroscopic liquid L and the air are cooled by the heat exchange coil 16. When the hygroscopic liquid L is cooled, it easily absorbs moisture in the air. In addition, when the air is cooled, the amount of saturated water vapor in the air decreases, so that moisture in the air is more easily absorbed by the hygroscopic liquid.

  The hygroscopic liquid L dropped from the hygroscopic liquid supply unit 15 adheres to the plate fins 61 of the heat exchange coil 16 and then flows downward through the plate fins 61 due to the action of its own weight. The hygroscopic liquid L that has flowed on the plate fin 61 falls off the plate fin 61 at the lower end of the plate fin 61. At this time, the hygroscopic liquid L at the time of leaving the plate fin 61 has, as an initial speed, the speed at which it has already flowed through the plate fin 61. Therefore, as the hydrophilicity of the plate fin 61 is smaller (that is, the resistance to the flow of the hygroscopic liquid L is smaller), the hygroscopic liquid L falls from the plate fin 61 at a higher speed. The hygroscopic liquid L falling from the plate fin 61 collides with the absorbent 27 and is absorbed by the absorbent 27. When an amount of the hygroscopic liquid L exceeding the absorption capacity of the absorbent material 27 is given to the absorbent material 27, the hygroscopic liquid L absorbed by the absorbent material 27 oozes out from the lower surface of the absorbent material 27, and drops into droplets. Then fall free (falls at an initial velocity of 0).

  In this way, the absorbent 27 receives and absorbs the hygroscopic liquid L that has fallen from the plate fins 61 of the heat exchange coil 16 at the initial speed, thereby absorbing the hygroscopic liquid L that has fallen from the plate fins 61 of the heat exchange coil 16. Is directly applied to the surface of the hygroscopic liquid L accumulated in the liquid tank 17 to prevent splashing. The hygroscopic liquid L that has oozed out of the absorbent material 27 falls freely as droplets and collides with the liquid surface of the hygroscopic liquid L accumulated in the liquid tank 17. Is 0, the speed at the time of collision is not large. In addition, since the lower surface of the absorbing material 27 where the free fall of the droplet starts is at a position lower than the lower end of the plate fin 61 of the heat exchange coil 16, compared to the case of dropping from the plate fin 61. The acceleration time will be shortened and the speed at the time of collision will not increase. Therefore, even if the free-falling hygroscopic liquid L collides with the liquid surface of the hygroscopic liquid L accumulated in the liquid tank 17, no splash is generated.

  The processor 10 collects the hygroscopic liquid L that has passed through the heat exchange coil 16 in the liquid tank 17 through the absorbent 27 as described above. The processor 10 sucks up the hygroscopic liquid L in the liquid tank 17 through the pipe 18 and supplies the hygroscopic liquid L again from the hygroscopic liquid supply unit 15. By circulating the hygroscopic liquid L placed in the liquid tank 17 in this manner, the hygroscopic liquid L can be efficiently utilized to adjust the humidity.

  When the processing machine 10 continues the dehumidifying operation, the hygroscopic liquid L is diluted and hardly absorbs moisture in the air, so the hygroscopic liquid L is regenerated by the regenerator 30. The humidity control apparatus 1 sends a part of the hygroscopic liquid L sucked out from the liquid tank 17 of the processor 10 to the regenerator 30 through the first hygroscopic liquid conduit 50. The amount of the hygroscopic liquid L sent to the regenerator 30 is adjusted by the three-way valve 20.

  The regenerator 30 regenerates the hygroscopic liquid L having a low solution concentration supplied from the first hygroscopic liquid conduit 50. Specifically, the regenerator 30 drops the hygroscopic liquid L supplied through the first hygroscopic liquid conduit 50 from the first supply unit 35a. The dropped hygroscopic liquid L is temporarily retained in the heat exchanger 36.

  At the same time as the above operation, the regenerator 30 operates the fan 34 to take in outside air, and supplies the taken outside air to the heat exchange coil 36 from below. Since the hygroscopic liquid L having a low solution concentration staying in the heat exchange coil 36 and the air come into contact with each other, the moisture of the hygroscopic liquid L escapes into the air. Moreover, since the heat exchange coil 36 functions as a condenser, the hygroscopic liquid L and air are heated by the heat exchange coil 36. When the hygroscopic liquid L is heated, the moisture in the hygroscopic liquid L is easily detached into the air. Further, when the air is heated, the saturated water vapor amount of the air increases, so that the moisture in the hygroscopic liquid L is more easily desorbed.

  The regenerator 30 collects the hygroscopic liquid L that has passed through the heat exchange coil 36 in the liquid tank 37 via the absorbent material 47. Also in the regenerator 30, the hygroscopic liquid L dropped from the heat exchange coil 36 at the initial speed is received and absorbed by the absorbent material 47. The hygroscopic liquid L absorbed by the absorbing material 47 oozes out from the lower surface of the absorbing material 47 and freely drops into the liquid tank 37 as droplets.

  The regenerator 30 sucks up the hygroscopic liquid L that has entered the liquid tank 37 through the pipe 38. The hygroscopic liquid L sucked up through the tube 38 is heated by the heating source 40. The regenerator 30 supplies the heated hygroscopic liquid L from the hygroscopic liquid supply unit 35b. By being heated by the heating source 40 in this way, the hygroscopic liquid L becomes in a state where moisture is more easily desorbed, and the hygroscopic liquid L can be efficiently regenerated. As the hygroscopic liquid L circulates between the heat exchange coil 36 and the liquid tank 37, the concentration of the hygroscopic liquid L gradually increases.

  The hygroscopic liquid L in the liquid tank 37 subjected to the regeneration process returns to the processing machine 10 through the second hygroscopic liquid pipe 51. The hygroscopic liquid L undergoes heat exchange with the hygroscopic liquid L toward the regenerator 30 by the heat exchanger 54 on the way back to the processor 10, and the temperature of the hygroscopic liquid L decreases. Heretofore, the dehumidifying operation of the humidity control apparatus 1 of the present embodiment has been described.

  Although the dehumidifying operation of the humidity control apparatus 1 of the present embodiment has been described above, the roles of the processing device 10 and the regenerator 30 may be switched when performing the humidifying operation. Specifically, the heat exchange coil 16 of the heat pump 21 is operated as a condenser, and the heat exchange coil 36 is operated as an evaporator. In addition, as a regeneration process of the hygroscopic liquid L in the humidifying operation, the valve 42 may be opened to supply water from the water supply means 41.

  Since the humidity control apparatus 1 according to the present embodiment is configured to retain the hygroscopic liquid L outside the plate fins 61 of the heat exchange coil 16, it is easy to perform a corrosion-resistant coating and can check the state of the coating. effective. Conventionally, since the heat exchanger for heating or cooling the hygroscopic liquid L has been provided in the pipeline that carries the hygroscopic liquid L, the corrosion resistant coating has to be performed in the pipeline. Since the pipe line is very small as compared with the casing 11 of the processing machine 10, it is not easy to perform a corrosion-resistant coating process or to check the coating state in the pipe line. In the example of the conventional heat exchanger, the distance between the plate fins is about 0.3 mm, and an appropriate coating process is difficult. The humidity control apparatus 1 according to the present embodiment can eliminate such inconvenience.

  The humidity control apparatus 1 according to the present embodiment has the above-described advantages, and the absorbent material 27 is provided below the heat exchange coil 16, so that the speed of the hygroscopic liquid L falling from the heat exchange coil 16 is reduced. In addition, the hygroscopic liquid L stored in the liquid tank 17 can be dropped. Thereby, the problem caused by replacing the filler with the heat exchange coil, that is, the hygroscopic liquid passing through the heat exchange coil collides with the liquid surface of the hygroscopic liquid stored in the liquid tank at high speed, and splashes are generated. The problem that fine particles of the hygroscopic liquid are scattered can be reduced.

  The humidity control apparatus of the present invention has been described in detail with reference to the embodiment, but the present invention is not limited to the above-described embodiment.

  In the embodiment described above, an example has been described in which both the processor and the regenerator have the absorbent material, but only one of the processor and the regenerator may have the absorbent material. In particular, when the exhaust port of the processor is facing the room and the exhaust port of the regenerator is facing the outside, an absorber is provided in the processor to reduce the scattering of hygroscopic liquid particles into the room. In addition, the regenerator may not be provided with an absorbent material.

  In the above-described embodiment, the heat exchange coil 16 having the plate fins 61 has been described as an example. However, a heat exchange coil having another configuration can be used.

  In the above-described embodiment, the example of the humidity control apparatus 1 using the heat pump 21 has been described. However, the humidity control apparatus of the present invention does not necessarily use the heat pump 21, and uses the hygroscopic liquid L to control the humidity. It is possible to apply any humidity control device that performs the above.

  FIG. 3 is a diagram showing a configuration of the humidity control apparatus 2 according to a modification of the first embodiment of the present invention. The basic configuration of the humidity control apparatus 2 shown in FIG. 3 is the same as the humidity control apparatus 1 of the above-described embodiment, but the humidity control apparatus 2 shown in FIG. 3 is not the heat pump 21 but the processing machine 10 side. The difference is that different heat sources 25 and 26 are used on the regenerator 30 side. For the heat sources 25 and 26 of the processor 10 and the regenerator 30, for example, a configuration that performs heat exchange with the hygroscopic liquid L by supplying cold water or hot water can be employed. Even with this configuration, as in the above-described embodiment, moisture is transferred between the air and the hygroscopic liquid L (latent heat exchange), and at the same time, the sensible heat between the air and the hygroscopic liquid L and the refrigerant of the heat pump. By changing the amount of saturated water vapor in the air by exchanging, the energy utilization efficiency can be increased.

(Second Embodiment)
The humidity control apparatus 3 according to the second embodiment includes a processing machine and a regenerator, as with the humidity control apparatus 1 according to the first embodiment. The basic configuration of the humidity control device 3 is the same as the humidity control device 1 of the above-described embodiment. In the humidity control device 3 of the present embodiment, dehumidification or humidification is performed using the processing device 60 and the regenerator 70. The method of performing is the same as the humidity control apparatus 1 of the first embodiment. The humidity control apparatus 3 of the present embodiment is different from the humidity control apparatus 1 of the first embodiment in the method of reducing the scattering of fine particles of the hygroscopic liquid inside the processor 60 and the regenerator 70. Hereinafter, a method for reducing scattering of fine particles of the hygroscopic liquid mainly in the humidity control apparatus 3 of the present embodiment will be described.

  FIG. 4 is a diagram illustrating a configuration of the humidity control apparatus 3 according to the second embodiment. As shown in FIG. 4, the processor 60 and the regenerator 70 have a configuration in which air to be dehumidified or humidified is taken into the housing from the side of the heat exchange coil.

  Hereinafter, the configuration of the processor 60 of the present embodiment will be described. The intake port 121 is provided on the side of the heat exchange coil 16. Specifically, the air inlet 121 is provided on the side wall of the housing 11 on the side of the heat exchange coil 16. A fan 141 is provided at the air inlet 121. The exhaust port 131 is provided on the side wall of the casing 11 opposite to the intake port 121 with the heat exchange coil 16 interposed therebetween. A fan 142 is also provided at the exhaust port 131.

  An absorber 271 is provided below the heat exchange coil 16. The configuration and action of the absorbent material 271 are the same as those of the absorbent material 27 of the first embodiment. In the processing machine 10 of the present embodiment, further, absorbent materials 272 and 273 having air permeability are provided on the side of the heat exchange coil 16. The absorbent material 272 is provided between the air inlet 121 and the heat exchange coil 16. The absorbent material 272 covers the entire side surface of the heat exchange coil 16. The absorber 273 is provided between the exhaust port 131 and the heat exchange coil 16. Similarly, the absorbent material 273 covers the entire side surface of the heat exchange coil 16. The absorbent materials 272 and 273 face the side surface of the heat exchange coil 16 that intersects the planar direction of the plate fin 61, and receive and absorb the hygroscopic liquid L that flows out from the plate fin 61 to the side.

  In the example of FIG. 4, the absorbent material 272 and the heat exchange coil 16 are in contact with each other. If the absorbent material 272 is in contact with the heat exchange coil 16, there is no space between the heat exchange coil 16 and the absorbent material 272 in which splashes of hygroscopic liquid leaking from the side surfaces of the heat exchange coil 16 are generated, The scattering of fine particles of the hygroscopic liquid can be reduced more reliably. The absorbent material 272 and the heat exchange coil 16 may be separated from each other. However, if the distance between the absorbent 272 and the heat exchange coil 16 is too long, the hygroscopic liquid L flowing out of the heat exchange coil 16 does not contact the absorbent 272 and the hygroscopic liquid L in the liquid tank 17 Dropping directly on the liquid surface may cause splashing. Therefore, the shorter the distance between the absorbent 272 and the heat exchange coil 16, the better. If the distance between the absorbent material 272 and the heat exchange coil 16 is sufficiently short, the hygroscopic liquid L flowing out from the side of the heat exchange coil 16 can be reliably received and absorbed by the absorbent material 272. When the collecting material 272 and the heat exchange coil 16 are separated, the distance between the absorbent material 272 and the heat exchange coil 16 is determined in consideration of these factors. From the above, the distance between the absorbent 272 and the heat exchange coil 16 is preferably 0 to 10 mm, more preferably 0 to 5 mm, and most preferably the absorbent 272 and the heat exchange coil 16 are in close contact with each other. It is that you are. The same applies to the distance between the absorbent 273 and the heat exchange coil 16.

  In the regenerator 70, similarly to the processor 60, the air inlet 321 is on the side of the heat exchange coil 36, and the air outlet 331 is on the opposite side of the air inlet 321 across the heat exchange coil 36. Fans 341 and 342 are provided at the intake port 321 and the exhaust port 331, respectively. Absorbing materials 472 and 473 are provided on the side of the heat exchange coil 36 corresponding to the intake port 321 and the exhaust port 331, and the absorbing material 471 is also provided below the heat exchange coil. These configurations are the same as those of the processor 60.

  Next, operation | movement of the humidity control apparatus 3 of this Embodiment is demonstrated. The outline of the operation of the humidity control device 3 is the same as that of the humidity control device 1 of the first embodiment. The processor 60 sucks up the hygroscopic liquid L having a high solution concentration from the liquid tank 17 and supplies it to the hygroscopic liquid supply unit 15. In the hygroscopic liquid supply unit 15, the hygroscopic liquid L is dropped from a plurality of nozzles. The dropped hygroscopic liquid L temporarily stays in the heat exchange coil 16.

  At the same time as the above operation, the processor 60 operates the fan 141 and the fan 142 to take in air to be dehumidified or humidified from the air inlet 121, and the taken-in air passes through the absorbent material 273 having air permeability. The heat exchange coil 16 is supplied from the side. At this time, air obtains a flow rate in the horizontal direction (horizontal direction) by the fan 141 provided in the intake port 121. By the action of this air, the hygroscopic liquid L staying on the plate fins 61 of the heat exchange coil 16 flows in the lateral direction (horizontal direction) and jumps out from the side end of the plate fins 61 on the side opposite to the air inlet 121. The hygroscopic liquid L jumping out from the side end of the plate fin 61 is absorbed by the absorbent material 272.

  When the hygroscopic liquid L in an amount exceeding the absorption capacity of the absorbent material 272 is given to the absorbent material 272, the hygroscopic liquid L absorbed by the absorbent material 272 oozes out from the lower surface of the absorbent material 272 and becomes liquid droplets. Fall freely. Droplets that fall freely from the absorbent material 272 are stored in the liquid tank 17.

  Thus, the absorbent 272 receives and absorbs the hygroscopic liquid L blown off by the fan 141 and ejected from the side of the plate fin 61 of the heat exchange coil 16, thereby absorbing the plate fin 61 of the heat exchange coil 16. The hygroscopic liquid L blown off from the side end is directly prevented from hitting the liquid surface of the hygroscopic liquid L accumulated in the liquid tank 17 to prevent splashing. The hygroscopic liquid L that oozes out from the absorbent 272 falls freely as droplets and collides with the liquid surface of the hygroscopic liquid L accumulated in the liquid tank 17. Is 0, the speed at the time of collision is not large. Therefore, even if the hygroscopic liquid L that has freely dropped from the lower surface of the absorbent material 272 collides with the liquid surface of the hygroscopic liquid L accumulated in the liquid tank 17, splashing does not occur. Moreover, since the side surface of the heat exchange coil 16 and the absorbent material 272 are in close contact as described above, splashing of the hygroscopic liquid L does not occur in the space between them.

  Similarly, the absorbent 273 absorbs the hygroscopic liquid L that has jumped out from the inlet 121 side of the heat exchange coil 16, so that the hygroscopic liquid L falls directly on the surface of the hygroscopic liquid L accumulated in the liquid tank 17. No, the occurrence of splashes of the hygroscopic liquid L is prevented. In addition, since the absorbent 273 and the heat exchange coil 16 are in close contact with each other, splashing of the hygroscopic liquid L does not occur in the space between them. In the regenerator 70 as well as the processor 60, the occurrence of splashes of the hygroscopic liquid L is prevented.

  As described above, according to the humidity control apparatus 3 of the present embodiment, the absorbent material 272, 273 absorbs the hygroscopic liquid L that jumps out from the side surface perpendicular to the planar direction of the plate fin 61 of the heat exchange coil 16, It is prevented that the hygroscopic liquid which came out from the side of the heat exchange coil 16 directly hits the liquid surface of the hygroscopic liquid L stored in the liquid tank, and splashing is prevented.

  In the present embodiment, the example in which the absorbent material 272 completely covers the side surface of the heat exchange coil 16 has been described, but the present invention is not limited to this. Even if the absorbent material 272 covers only a part of the side surface of the heat exchange coil 16, the absorbent material 272 can absorb the hygroscopic liquid blown off from at least a part of the side of the plate fin 61. As long as the above-mentioned effects can be obtained.

  Moreover, in said embodiment, you may comprise the absorbers 271-273 integrally. Further, an absorbent material may be provided also on the heat exchange coil 16 so that the absorbent material surrounds the entire circumference of the heat exchange coil 16. At this time, you may comprise integrally the absorber surrounding the perimeter of a heat exchange coil. Moreover, it is good also as a structure which does not provide the absorber 273 by the side of the inlet 121, and it is good also as a structure which does not provide the absorber 271 below the heat exchange coil 16.

  In the above embodiment, the exhaust port 131 is provided on the side of the heat exchange coil 16, but the exhaust port 131 may be provided on the upper surface of the housing 11 as in the first embodiment.

(Third embodiment)
FIG. 5 is a cross-sectional view of the heat exchange coil 161 according to the fourth embodiment. In the heat exchange coil 161, a plurality of plate fins 61 are arranged in parallel, as in the heat exchange coil 16 of the first and second embodiments. An absorbent material 274 is inserted between each of the adjacent plate fins 61.

  The hygroscopic liquid L dropped from above toward the heat exchange coil 161 is absorbed by the absorbent 274 inserted between the plate fins 61. When the amount of the hygroscopic liquid L absorbed by the absorbent 274 increases, the hygroscopic liquid L freely drops as droplets from the lower surface of the absorbent 274. The liquid droplets dropped from the absorbent material 274 are stored in the liquid tank 17.

  The heat exchange coil 161 of the present embodiment can be applied to a humidity control device of a type that allows air to flow upward (counter direction) as in the humidity control device 1 of the first embodiment. The present invention can also be applied to a humidity control device of a type that flows air in the lateral direction (cross direction) as in the humidity control device 3 of FIG.

  In the heat exchange coil 161 of the present embodiment, the hygroscopic liquid L dripped from the hygroscopic liquid supply unit 15 proceeds in the direction of gravity through the absorbent 274 and oozes out from the lower surface of the heat exchange coil 161, so that the liquid tank Fall to 17. The initial velocity of the droplet of the hygroscopic liquid L when dropping from the lower surface of the heat exchange coil 161 is zero. Therefore, even if the droplet hits the liquid surface of the hygroscopic liquid L stored in the liquid tank 17, no splash occurs.

  In the heat exchange coil 161 of the present embodiment, the hygroscopic liquid L is held in the heat exchange coil 161 by the absorbent material 274. Thereby, the residence time of the hygroscopic liquid L in the heat exchange coil 16 becomes longer, and the time for the hygroscopic liquid L to come into contact with air becomes longer, so that the energy utilization efficiency is improved.

  As described above, the heat exchange coil 161 according to the present embodiment extends the residence time of the hygroscopic liquid and maintains the temperature of the retained hygroscopic liquid at a low temperature or a high temperature. Can improve efficiency. Thereby, the dripping amount of the hygroscopic liquid with respect to the amount of air to be dehumidified or humidified can be reduced.

  In the present embodiment, the absorbent material 274 is inserted so as to fill the space between the plate fins 61 of the heat exchange coil 161, but the present invention is not limited to this. For example, the absorbent material 274 may be attached to both surfaces of the plate fins 61, and there may be a gap between the absorbent materials attached to the opposing surfaces of the adjacent plate fins 61.

  In the present embodiment, the absorbent material 274 having a length substantially corresponding to the vertical length of the heat exchange coil 161 is inserted into the gap between the plate fins 61. It may be inserted only in the lower half of the.

  In the present invention, the hygroscopic liquid is temporarily retained in the heat exchange coil, and air is passed through the hygroscopic liquid while being heated or cooled by the heat exchange coil, and the falling speed of the hygroscopic liquid is reduced by the absorbent. Thus, the energy use efficiency can be improved and the scattering of the hygroscopic liquid can be reduced, and the apparatus is useful as a humidity control apparatus that performs humidity control using the hygroscopic liquid.
