Description

  The present invention relates to a humidity control apparatus that performs humidity control using a hygroscopic liquid.

  Conventionally, as described in Patent Document 1, Patent Document 2, and the like, for example, a humidity control apparatus that performs humidity control using a hygroscopic liquid such as lithium chloride has been known. A humidity control apparatus using a hygroscopic liquid has a processing machine and a regenerator. The processor takes in air, performs dehumidification or humidification by gas-liquid contact between the taken-in air and the hygroscopic liquid, and discharges the processed air to the humidity control space. The regenerator regenerates the hygroscopic liquid whose concentration is changed by using the processor.

  Here, the regeneration of the hygroscopic liquid means returning the hygroscopic liquid whose concentration has been changed by adjusting the humidity to a state before being used for the humidity adjustment. For example, in the case of dehumidification, moisture in the air is absorbed by the hygroscopic liquid, so that the solution concentration of the hygroscopic liquid becomes low. Since sufficient dehumidification cannot be performed with a hygroscopic liquid having a low solution concentration, the hygroscopic liquid having a high solution concentration is restored by releasing moisture from the hygroscopic liquid. On the contrary, in the case of humidification, the solution concentration of the hygroscopic liquid becomes high, so that the hygroscopic liquid is returned to the hygroscopic liquid having a low solution concentration by absorbing moisture.

A hygroscopic liquid with a high solution concentration absorbs moisture when the temperature decreases, and a hygroscopic liquid with a low solution concentration releases moisture when the temperature increases. A conventional humidity control apparatus utilizes this property to adjust the temperature of the hygroscopic liquid supplied to the processor and the regenerator to regenerate the humidity control and hygroscopic liquid. For example, in the case of dehumidification, the moisture in the air is absorbed by the hygroscopic liquid by cooling the hygroscopic liquid having a high solution concentration and passing air through the cooled hygroscopic liquid.

  The present invention provides a humidity control device that improves the efficiency of moisture exchange by gas-liquid contact between air and a hygroscopic liquid and improves the efficiency of dehumidification or humidification with a simple configuration.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus including a regenerator, wherein the processing unit includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. A fan for taking air into the housing through an air inlet formed in the housing, and a flow resistance adjustment for adjusting the flow resistance of the air outlet formed in the housing A part.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus comprising a regenerator, wherein the regenerator includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. A fan for taking air into the housing through an air inlet formed in the housing, and a flow resistance adjustment for adjusting the flow resistance of the air outlet formed in the housing A part.

  In this way, by adjusting the flow path resistance of the discharge port by the flow path resistance adjusting unit, it is possible to change the atmospheric pressure in the housing of the processing machine or the regenerator with a simple configuration. That is, when the flow path resistance of the discharge port is increased, air is not easily discharged from the housing, but air is pushed in by the fan, so that the atmospheric pressure in the housing increases. Since the water vapor contained in the air is liable to be liquefied when the atmospheric pressure is increased, the hygroscopic liquid efficiently absorbs moisture in the air. When this configuration is used in a processor, dehumidification can be performed efficiently, and when used in a regenerator, regeneration processing for diluting a hygroscopic liquid can be performed efficiently.

  In the humidity control apparatus, the flow path resistance adjustment unit increases the flow path resistance of the discharge port when the gas-liquid contact unit performs a process of removing moisture in the air, and the gas-liquid contact unit When performing a process of releasing moisture into the air, the flow path resistance of the discharge port may be reduced.

  Thus, by reducing the flow path resistance of the discharge port when performing the process of releasing moisture, the atmospheric pressure inside the casing is made to be approximately the same as the atmospheric pressure outside the casing. Thereby, it can prevent from the process which discharge | releases a water | moisture content from a hygroscopic liquid in the air, and can apply the structure of a flow-path resistance adjustment part to the humidity controller which can perform both dehumidification and humidification. Note that the state where the flow path resistance is large is a resistance that causes a difference in atmospheric pressure between the inside and the outside of the housing.

  The said humidity control apparatus may use the damper which adjusts the opening degree of the said discharge port as said flow-path resistance adjustment part.

  The opening degree of the discharge port can be reduced by the damper, and the flow path resistance of the discharge port can be increased.

  The said humidity control apparatus may provide a 2nd fan in the said discharge port as said flow-path resistance adjustment part.

  By rotating the second fan provided at the discharge port at a speed different from that of the air intake fan, the flow path resistance of the discharge port can be changed. Specifically, by rotating the second fan at a speed that discharges a smaller amount of air than the amount of air taken in, the air pressure in the housing increases due to the difference between the amount of air taken in and the amount of air discharged. Further, the second fan may rotate in the direction of taking in air. In this case, the rotation amount of the second fan is a speed at which a smaller amount of air is taken in than the amount of air taken in by the fan at the intake port. Thereby, since the air taken in from the intake port goes out of the housing, the air pressure in the housing becomes high enough to overcome the air intake force by the second fan. Therefore, the atmospheric pressure in the housing can be further increased.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus including a regenerator, wherein the processing unit includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. Through the flow path resistance adjusting unit for adjusting the flow resistance of the air intake port formed in the housing and the air discharge port formed in the housing to the humidity control space from the inside of the housing And a fan for discharging air.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus comprising a regenerator, wherein the regenerator includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. The humidity control space from the inside of the housing through the flow resistance adjustment portion for adjusting the flow resistance of the air intake port formed in the housing and the air discharge port formed in the housing. And a fan for discharging air to the outside.

  In this way, by adjusting the flow path resistance of the intake port by the flow path resistance adjusting unit, it is possible to change the atmospheric pressure in the housing of the processing machine or the regenerator with a simple configuration. That is, if the flow path resistance of the intake port is increased, air is less likely to be taken in from the intake port, but air is forcibly discharged from the housing by the action of the fan, so the atmospheric pressure in the housing is lowered. . When the atmospheric pressure is lowered, the moisture in the hygroscopic liquid is easily released into the air. When this configuration is used in a processing machine, the humidification process can be performed efficiently, and when used in a regenerator, the regeneration process for concentrating the hygroscopic liquid can be performed efficiently.

  In the humidity control apparatus, the flow path resistance adjustment unit reduces the flow path resistance of the intake port when performing a process of removing moisture in the air at the gas-liquid contact unit, When performing a process of releasing moisture into the air, the flow path resistance of the intake port may be increased.

  Thus, by reducing the flow path resistance of the outlet when performing the process of removing moisture, the atmospheric pressure inside the casing is made to be approximately the same as the atmospheric pressure outside the casing. Thereby, it is possible not to interfere with the process of removing moisture in the air, and the configuration of the flow path resistance adjustment unit can be applied to a humidity controller that can perform both dehumidification and humidification. Note that the state where the flow path resistance is large is a resistance that causes a difference in atmospheric pressure between the inside and the outside of the housing.

  The said humidity control apparatus may use the damper which adjusts the opening degree of the said intake port as said flow-path resistance adjustment part.

  The opening degree of the discharge port can be reduced by the damper, and the flow path resistance of the discharge port can be increased.

  The said humidity control apparatus may provide a 2nd fan in the said intake port as said flow-path resistance adjustment part.

  By rotating the second fan provided at the intake port at a speed different from that of the air discharge fan, the flow path resistance of the intake port can be changed. Specifically, by rotating the second fan at a speed that takes in an amount of air that is smaller than the amount of air discharged, the atmospheric pressure in the housing is lowered due to the difference between the air intake amount and the air discharge amount. Further, the second fan may rotate in the direction of discharging air. In this case, the rotation amount of the second fan is set to a speed at which a smaller amount of air is discharged than the amount of air discharged from the discharge port. Thereby, since air is taken into the housing from the intake port, the difference in atmospheric pressure between the outside of the housing and the inside of the housing becomes large enough to overcome the air discharging force by the second fan. Therefore, the atmospheric pressure in the housing can be further reduced.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus including a regenerator, wherein the processing unit includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. A first fan provided in an air intake port formed in the housing, and a second fan provided in an air discharge port formed in the housing, wherein the gas-liquid contact When the process of removing moisture in the air is performed at the section, the amount of rotation of the first fan in the direction of taking in the air is made larger than the amount of rotation of the second fan, and the air-liquid contact section When discharging the air from the second fan when processing to release moisture The rotation amount to be larger than the amount of rotation of the first fan.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus comprising a regenerator, wherein the regenerator includes a temperature control unit that controls a temperature of the hygroscopic liquid, and a housing that houses a gas-liquid contact unit that brings air into contact with the hygroscopic liquid. A first fan provided in an air intake port formed in the housing, and a second fan provided in an air discharge port formed in the housing, wherein the gas-liquid contact When the process of removing moisture in the air is performed at the section, the amount of rotation of the first fan in the direction of taking in the air is made larger than the amount of rotation of the second fan, and the air-liquid contact section When discharging the air from the second fan when processing to release moisture The rotation amount to be larger than the amount of rotation of the first fan.

  With this configuration, the atmospheric pressure in the housing can be controlled by the difference in the rotation amount between the first fan and the second fan. That is, by making the amount of rotation of the first fan in the direction of taking in air larger than the amount of rotation of the second fan, the force for taking in air into the case becomes larger than the force for discharging air from inside the case. , The atmospheric pressure inside the housing is increased. Conversely, by making the amount of rotation of the second fan in the direction of discharging air larger than the amount of rotation of the first fan, the force for discharging air from the inside of the housing is greater than the force for taking air into the housing. It becomes larger and the atmospheric pressure inside the housing becomes lower. Without changing the air flow from the intake port to the discharge port, the pressure inside the housing can be made higher or lower than the humidity control space. By controlling the atmospheric pressure in the housing in this way, moisture can be efficiently exchanged both when performing a process for removing moisture in the air and when performing a process for releasing moisture into the air.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus including a regenerator, wherein the processor includes a temperature control unit that controls a temperature of the hygroscopic liquid, a first air port, and a second air port smaller than the first air port. Formed in the housing, a gas-liquid contact portion that contacts the air and the hygroscopic liquid, and the intake of air into the housing through the first air port and the housing. A fan capable of switching air discharge from the body to the humidity control space, and performing the process of removing moisture in the air at the gas-liquid contact portion, the first air port by the fan Air is taken in and discharged from the second air port. When performing the process of releasing moisture into the air by the gas-liquid contact portion to discharge air from the first air outlet by the fan takes in air from the second air inlet.

  The humidity control apparatus of the present invention regenerates a treatment machine that adjusts the humidity of the humidity control space by gas-liquid contact between air and a hygroscopic liquid, and a diluted or concentrated hygroscopic liquid that is used in the treatment machine. A humidity control apparatus including a regenerator, wherein the processor includes a temperature control unit that controls a temperature of the hygroscopic liquid, a first air port, and a second air port smaller than the first air port. Formed in the housing, a gas-liquid contact portion that contacts the air and the hygroscopic liquid, and the intake of air into the housing through the first air port and the housing. And a fan capable of switching between exhausting air from the body, and when performing a process of removing moisture in the air at the gas-liquid contact portion, air is taken in from the first air port by the fan. The air is discharged from the second air port and the gas-liquid contact When performing the process of releasing moisture into the air and discharging air from said first air outlet by the fan at, taking in air from the second air inlet.

  Thus, in the housing having the second air port smaller than the first air port, the air pressure in the housing is lower and higher than the air pressure outside the housing by having the configuration in which the air flow direction is switched by the fan. Adjustable between states. That is, the air pressure in the housing can be increased by taking air from the first air port, and the air pressure in the housing can be decreased by discharging air from the first air port. By controlling the atmospheric pressure in the housing in this way, moisture can be efficiently exchanged both when performing a process for removing moisture in the air and when performing a process for releasing moisture into the air.

  In the humidity control apparatus, the first air port and the second air port may be formed at a position where air flows in a direction intersecting the flow of the hygroscopic liquid in the gas-liquid contact portion.

  With this configuration, even when air is taken in or discharged from the first air port, it contacts so as to intersect with the hygroscopic liquid, so even when processing for removing moisture in the air is performed, Efficient gas-liquid contact can also be realized when performing a process of releasing moisture.

  According to the present invention, by adjusting the flow path resistance of the discharge port by the flow path resistance adjustment unit, the atmospheric pressure in the housing is increased with a simple configuration, so that the hygroscopic liquid efficiently absorbs moisture in the air. Can be. In addition, by adjusting the flow path resistance of the intake port by the flow path resistance adjustment unit, the atmospheric pressure in the housing can be lowered with a simple configuration, and the moisture in the hygroscopic liquid can be efficiently released.

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 apparatus 1 includes a processing device 10 that takes in air from outside the humidity control space or from the humidity control space, and adjusts the intake air by gas-liquid contact with the hygroscopic liquid L, and a humidity control process in the processing device 10. And a regenerator 40 that regenerates the hygroscopic liquid L used in the above.

  Here, the regeneration of the hygroscopic liquid L refers to returning the hygroscopic liquid L whose concentration has been changed to a state before being used for the humidity control process by performing humidity control. For example, in the case of dehumidifying treatment, moisture in the air is absorbed by the hygroscopic liquid L by cooling the hygroscopic liquid L having a high solution concentration and passing air through the cooled hygroscopic liquid L. Although the solution concentration of the hygroscopic liquid L is lowered by this treatment, the hygroscopic liquid L having a low solution concentration cannot perform sufficient dehumidification. The hygroscopic liquid L having a high solution concentration is returned to the hygroscopic liquid L having a high solution concentration by a regeneration process for desorbing moisture from the hygroscopic liquid L having a low solution concentration. In the case of the humidification process, conversely, since the solution concentration of the hygroscopic liquid L is increased, the hygroscopic liquid L is returned to the low solution concentration by the regeneration process in which the hygroscopic liquid L absorbs moisture.

  In the present embodiment, lithium chloride (LiCl) is used as the hygroscopic liquid L. The hygroscopic liquid L 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, propylene glycol, and other hygroscopic properties. You may use the cheap liquid which has.

  The processor 10 is an indoor unit that adjusts the humidity of indoor air, and the regenerator 40 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 40 is connected to one processor 10, a configuration in which one regenerator 40 is connected to a plurality of processors 10 may be adopted. For example, when installing the humidity control apparatus 1 in an apartment house or a large supermarket, the processor 10 is installed in each room or floor, and one regenerator 40 connected to each processor 10 is installed outside. It can also be set as the aspect to do.

  The processor 10 and the regenerator 40 are connected by a first hygroscopic liquid conduit 61 and a second hygroscopic liquid conduit 62. The first hygroscopic liquid pipe 61 is a pipe for sending the hygroscopic liquid L from the processor 10 to the regenerator 40, and the second hygroscopic liquid pipe 62 is a hygroscopic pipe from the regenerator 40 to the processor 10. This is a conduit for feeding the sex liquid L. By using the first hygroscopic liquid pipe 61 and the second hygroscopic liquid pipe 62 to circulate the hygroscopic liquid L between the processing machine 10 and the regenerator 40, the moisture absorption used in the processing machine 10. The organic liquid L is regenerated by the regenerator 40 and returned to the processor 10.

[Processing machine]
Next, the configuration of the processor 10 will be described. The processing machine 10 includes a housing 11 that contains a filler 14 for performing gas-liquid contact between air and the hygroscopic liquid L, and a hygroscopic liquid supply unit 15 that drops the hygroscopic liquid L on the filler 14. It has. The filler 14 has a role of temporarily retaining the hygroscopic liquid L dropped from the hygroscopic liquid supply unit 15. In addition, a liquid tank 16 that stores the hygroscopic liquid L that has passed through the filler 14 is provided at the lower portion of the housing 11.

  The housing 11 is formed with an intake port 12 for taking in air and an exhaust port 13 for discharging air. The intake 12 is provided with a fan 17 for sending air into the housing 11. Air is sent into the housing 11 by the fan 17. Although there is no fan at the discharge port 13, air is discharged from the discharge port 13 when air is sent from the intake port 12. In FIG. 1, arrows indicate the flow of air. As shown in FIG. 1, the air taken in from the intake 12 passes through the filler 14. Since the hygroscopic liquid L stays in the filler 14, moisture is exchanged between the hygroscopic liquid L and the air passing through the filler 14, and dehumidification or humidification is performed.

  The discharge port 13 is provided with a damper 18 that adjusts the size of the opening. When the opening degree of the damper 18 is increased, the air in the housing 11 flows smoothly into the humidity control space through the discharge port 13. When the opening degree of the damper 18 is reduced, the flow path resistance of the discharge port 13 is increased. In this case, while air is sent into the housing 11 by the fan 17, it becomes difficult for air to come out from the discharge port 13, so the atmospheric pressure in the housing 11 becomes high.

  The processing machine 10 has a pipe 19 for supplying the hygroscopic liquid L in the liquid tank 16 to the hygroscopic liquid supply unit 15. A pump 20 is attached to the pipe 19 to suck up the hygroscopic liquid L in the liquid tank 16.

  The pipe 19 is provided with a first heat exchanger 31 of a heat pump 30, and the hygroscopic liquid L is heated or cooled by the first heat exchanger 31. The first heat exchanger 31 controls the temperature of the hygroscopic liquid L supplied to the hygroscopic liquid supply unit 15 of the processor 10. 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 the humidification process, the hygroscopic liquid L is heated in order to release the moisture contained in the hygroscopic liquid L into the air. Conversely, when the processor 10 performs the dehumidifying process, the hygroscopic liquid L is cooled in order to make the hygroscopic liquid L easily absorb moisture in the air.

  The first hygroscopic liquid pipe 61 for sending the hygroscopic liquid L in the liquid tank 16 to the regenerator 40 is connected to the pipe 19 for sucking the hygroscopic liquid L from the liquid tank 16 through the three-way valve 21. ing. The three-way valve 21 controls the amount of the hygroscopic liquid L sent to the hygroscopic liquid supply unit 15 of the processing machine 10 and the amount of the hygroscopic liquid L sent to the regenerator 40 through the first hygroscopic liquid conduit 61. In the present embodiment, the three-way valve 21 is configured such that (amount of hygroscopic liquid L sent to the hygroscopic liquid supply unit 15): (amount of hygroscopic liquid L sent to the regenerator 40) is from 8: 2 to 9: 1. Control to be a percentage.

  The first hygroscopic liquid conduit 61 is provided with a second heat exchanger 32 that cools or heats the hygroscopic liquid L supplied to the regenerator 40. The second heat exchanger 32 controls the temperature of the hygroscopic liquid L supplied to the regenerator 40. The first heat exchanger 31 and the second heat exchanger 32 constitute a heat pump 30, and heat moves between the first heat exchanger 31 and the second heat exchanger 32.

  Here, the configuration of the heat pump 30 will be described. The heat pump 30 includes a first heat exchanger 31, a second heat exchanger 32, a compressor 33, an expansion valve 34, and a refrigerant pipe 35 that connects them. The heat pump 30 can cause the first heat exchanger 31 to function as an evaporator or a condenser by reversing the flow of the refrigerant. The second heat exchanger 32 performs a process opposite to that of the first heat exchanger 31.

[Playback machine]
Next, the playback device 40 will be described. The regenerator 40 regenerates the hygroscopic liquid L by bringing the hygroscopic liquid L sent from the processor 10 into air-liquid contact. The regenerator 40 includes a casing 41 that houses a filler 44 for performing gas-liquid contact between air and the hygroscopic liquid L, and a hygroscopic liquid supply unit 45 that drops the hygroscopic liquid L on the filler 44. have. In addition, a liquid tank 46 that stores the hygroscopic liquid L that has passed through the filler 44 is provided at the lower portion of the housing 41.

  The hygroscopic liquid supply unit 45 is filled with the hygroscopic liquid supply unit 45 a that supplies the hygroscopic liquid L sent through the first hygroscopic liquid pipe 61 to the filler 44, and the hygroscopic liquid L sucked up from the liquid tank 46. And a hygroscopic liquid supply unit 45 b for supplying the material 44. Whether the second heat exchanger 32 of the heat pump 30 provided in the first hygroscopic liquid pipe 61 heats or cools the hygroscopic liquid L is whether the hygroscopic liquid L is concentrated or diluted by the regenerator 40. by. That is, when the regenerator 40 concentrates the hygroscopic liquid L, the hygroscopic liquid L is heated in order to release the moisture contained in the hygroscopic liquid L into the air. On the contrary, when the regenerator 40 dilutes the hygroscopic liquid L, the hygroscopic liquid L is cooled in order to make the hygroscopic liquid L easily absorb moisture in the air.

  The housing 41 is formed with an intake port 42 for taking in air and an exhaust port 43 for discharging air. The discharge port 43 is provided with a fan 47 for discharging air from the inside of the housing 41. By discharging the air in the housing 41 to the outside by the fan 47, the inside of the housing 41 becomes a negative pressure with respect to the outside of the housing 41, so that the air flows into the housing 41 through the intake port 42.

  In FIG. 1, arrows indicate the flow of air. As shown in FIG. 1, the air taken in from the intake 42 passes through the filler 44. Since the hygroscopic liquid L stays in the filler 44, moisture is exchanged between the hygroscopic liquid L and air. Thereby, the hygroscopic liquid L is regenerated.

  The intake port 42 is provided with a damper 48 that adjusts the size of the opening. When the opening degree of the damper 48 is increased, the air smoothly flows into the housing 41 through the intake port 42. When the opening degree of the damper 48 is reduced, the flow path resistance of the intake port 42 is increased. In this case, air is discharged from the inside of the casing 41 to the outside by the fan 47, but air is difficult to enter from the intake port 42, so that the atmospheric pressure in the casing 41 becomes low.

  The regenerator 40 has a pipe 49 that supplies the hygroscopic liquid L in the liquid tank 46 to the first hygroscopic liquid conduit 61. The hygroscopic liquid L in the liquid tank 46 is sucked up by the pump 50 to the first hygroscopic liquid pipe 61. The hygroscopic liquid L is supplied again to the regenerator 40 through the second heat exchanger 32.

  The regenerator 40 has a supply pipe 51 for supplying the hygroscopic liquid L in the liquid tank 46 to the hygroscopic liquid supply unit 45b. A pump 52 is attached to the supply pipe 51 and sucks up the hygroscopic liquid L in the liquid tank 46. The tube 51 is provided with a heating source 53. The heating source 53 heats the hygroscopic liquid L sucked up from the liquid tank 46 when it is desired to increase the temperature in addition to the temperature control by the second heat exchanger 32. The heated hygroscopic liquid L is dropped onto the filler 44 from the hygroscopic liquid supply unit 45 b and is brought into gas-liquid contact with the filler 44. The hygroscopic liquid L that has passed through the filler 44 enters the liquid tank 46. By circulating the hygroscopic liquid L in this way, the regenerator 40 performs a regeneration process of the hygroscopic liquid L.

  The regenerator 40 has a water supply pipe 54 that supplies water to the liquid tank 46. A valve 55 is provided on the water supply pipe 54, and water supply is controlled by the valve 55.

  The hygroscopic liquid L in the liquid tank 46 returns to the processor 10 through the second hygroscopic liquid conduit 62. The amount of the hygroscopic liquid L that returns from the regenerator 40 to the processor 10 is adjusted by a valve 63. In the present embodiment, the valve 63 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 46 is constant.

  The humidity control apparatus 1 includes a heat exchanger 64 that performs heat exchange between the first hygroscopic liquid pipe 61 and the second hygroscopic liquid pipe 62. This heat exchanger 64 reduces the temperature difference between the hygroscopic liquid L flowing through the first hygroscopic liquid conduit 61 and the hygroscopic liquid L flowing through the second hygroscopic liquid conduit 62, and the pumping temperature difference of the heat pump 30 is reduced. Contributes to reduction.

[Operation of humidity control device]
Next, operation | movement of the humidity control apparatus 1 of this Embodiment is demonstrated. First, the operation when the humidity control apparatus 1 performs a dehumidifying process will be described. In this case, the heat pump 30 causes the first heat exchanger 31 to function as an evaporator and the second heat exchanger 32 as a condenser. A hygroscopic liquid L having a high solution concentration is placed in the liquid tank 16 of the processor 10.

  The processor 10 sucks up the hygroscopic liquid L having a high solution concentration from the liquid tank 16, cools the hygroscopic liquid L in the first heat exchanger 31 functioning as an evaporator, and supplies the hygroscopic liquid L to the hygroscopic liquid supply unit 15. To do. In the air treatment unit 11, the hygroscopic liquid L is dropped onto the filler 14. The dropped hygroscopic liquid L slowly passes through the filler 14 and returns to the liquid tank 16.

  At the same time as the above operation, the processor 10 takes air into the housing 11 by the fan 17 provided at the intake port 12, passes through the space between the fillers 14, and then discharges it into the humidity control space through the discharge port 13. To do. Since the filler 14 contains the hygroscopic liquid L having a high solution concentration and a low temperature, the moisture in the air is absorbed by the hygroscopic liquid L, and the discharged air is dehumidified. In addition, heat exchange is also performed simultaneously between the hygroscopic liquid L and air, and exhaust air is cooled.

  When the dehumidifying process is performed, the processor 10 reduces the opening degree of the damper 18 of the discharge port 13. FIG. 2A is a diagram illustrating the atmospheric pressure in the housing 11 during the dehumidifying process. As shown in FIG. 2A, by reducing the opening of the damper 18, the discharge port 13 is narrowed and the flow path resistance is increased, so that the atmospheric pressure in the housing 11 is increased from the outside of the housing 11. Get higher. Thus, when the atmospheric pressure in the housing 11 is increased, the water vapor in the air is easily liquefied. Therefore, the moisture absorption rate in the air by the hygroscopic liquid L is improved as compared with the case where the atmospheric pressure in the housing 11 is the same as the external atmospheric pressure (hereinafter referred to as “natural pressure”).

  When the processing machine 10 continues the dehumidifying operation, the hygroscopic liquid L is diluted and it becomes difficult to absorb moisture in the air, so the hygroscopic liquid L is regenerated by the regenerator 40. The humidity control apparatus 1 supplies a part of the hygroscopic liquid L sucked from the liquid tank 16 of the processor 10 to the first hygroscopic liquid pipe 61 and sends it to the regenerator 40. The amount of the hygroscopic liquid L sent to the regenerator 40 is adjusted by the three-way valve 21.

  A second heat exchanger 32 functioning as a condenser is disposed in the middle of the first hygroscopic liquid pipe 61, and the hygroscopic liquid L sent to the regenerator 40 is the second heat exchanger 32. Heated by. The regenerator 40 regenerates the hygroscopic liquid L having a low solution concentration supplied from the first hygroscopic liquid conduit 61. Specifically, the hygroscopic liquid supply unit 45 a drops the hygroscopic liquid L heated by the second heat exchanger 32 onto the filler 44. The dropped hygroscopic liquid L enters the liquid tank 46 through the filler 44.

  At the same time as the above operation, the regenerator 40 discharges air from the inside of the casing 41 by the fan 47 provided at the discharge port 43. Thereby, air flows into the housing 41 through the intake port 42. The air that has flowed in passes through the filler 44 and is discharged from the discharge port 43. When the air contacts the hygroscopic liquid L, moisture is desorbed from the high temperature hygroscopic liquid L and escapes into the air, and the concentration of the hygroscopic liquid L increases. The hygroscopic liquid L that has passed through the filler 44 enters the liquid tank 46.

  The regenerator 40 reduces the opening degree of the damper 48 of the intake 42 when performing the regeneration for concentrating the hygroscopic liquid L. As shown in FIG. 2A, by reducing the opening of the damper 48, the intake port 42 is narrowed and the flow path resistance is increased, so that the air pressure in the housing 41 is increased from the outside of the housing 41. Lower. Thus, when the atmospheric | air pressure in the housing | casing 41 becomes low, it will be in the state in which the water | moisture content in the hygroscopic liquid L is easy to be discharge | released in the air. Therefore, the hygroscopic liquid L is easily concentrated as compared with the case where the atmospheric pressure in the housing 11 is a natural pressure.

  Part of the hygroscopic liquid L in the liquid tank 46 is sucked up by the pump 52 and supplied to the hygroscopic liquid supply unit 45 b through the supply pipe 51. At this time, the hygroscopic liquid L is heated by the heating source 53. Therefore, the moisture of the hygroscopic liquid L is more easily released, and the regenerator 40 can perform an efficient concentration process.

  A part of the hygroscopic liquid L in the liquid tank 46 is supplied to the first hygroscopic liquid pipe 61. The hygroscopic liquid L supplied to the first hygroscopic liquid conduit 61 is heated by the second heat exchanger 32 and supplied again to the hygroscopic liquid supply unit 45a. As the hygroscopic liquid L circulates between the filler 44 and the liquid tank 46 in this way, the concentration of the hygroscopic liquid L gradually increases.

  The hygroscopic liquid L in the liquid tank 46 that has been subjected to the regeneration process returns to the processor 10 through the second hygroscopic liquid conduit 62. The hygroscopic liquid L undergoes heat exchange with the hygroscopic liquid L toward the regenerator 40 by the heat exchanger 64 on the way back to the processor 10, and the temperature decreases. Heretofore, the dehumidifying operation of the humidity control apparatus 1 of the present embodiment has been described.

  Next, the operation when the humidifying process is performed by the humidity control apparatus 1 will be described. When humidifying is performed by the humidity control apparatus 1, the heat pump 30 causes the first heat exchanger 31 to function as a condenser and the second heat exchanger 32 to function as an evaporator. A hygroscopic liquid L having a low solution concentration (containing a lot of water) is placed in the liquid tank 16 of the processing machine 10. In the case of the humidification process, basically, the humidity controller 1 performs an operation opposite to the dehumidification process.

  While the processor 10 heats the hygroscopic liquid L having a low solution concentration and drops it onto the filler 14, the processor 10 releases the moisture from the hygroscopic liquid L by passing the taken-in air through the filler 14. Humidify. In addition, heat exchange is also performed simultaneously between the hygroscopic liquid L and air, and exhaust air is heated.

  When the humidification process is performed, the damper 18 of the processor 10 has a large opening. FIG.2 (b) is a figure which shows the atmospheric | air pressure in the housing | casing 11 in the case of performing a humidification process. As shown in FIG. 2B, since the opening degree of the damper 18 is increased, the atmospheric pressure in the housing 11 of the processing machine 10 is the same as the natural pressure. As in the dehumidifying process, when the atmospheric pressure in the housing 11 is increased (see FIG. 2A), moisture is hardly released from the hygroscopic liquid L, and the efficiency of the humidifying process is reduced. When the processing is performed, such an inconvenience does not occur by increasing the opening of the damper.

  When the processing device 10 continues the humidification operation, the hygroscopic liquid L is concentrated and the moisture released into the air is reduced, so that the hygroscopic liquid L is regenerated by the regenerator 40. The humidity control apparatus 1 supplies a part of the hygroscopic liquid L sucked from the liquid tank 16 of the processor 10 to the first hygroscopic liquid pipe 61 and sends it to the regenerator 40.

  The hygroscopic liquid L sent to the regenerator 40 is cooled by the second heat exchanger 32 in the first hygroscopic liquid conduit 61. The cooled hygroscopic liquid L is supplied to the hygroscopic liquid supply unit 45a of the regenerator 40. Regeneration in which the hygroscopic liquid L absorbs moisture by passing the air taken in from the outside through the filler 44 while dropping the hygroscopic liquid L having a high concentration cooled by the hygroscopic liquid supply unit 45a onto the filler 44. Process. The hygroscopic liquid L that has passed through the filler 44 enters the liquid tank 46.

  Part of the hygroscopic liquid L in the liquid tank 46 is sucked up by the pump 52 and supplied to the hygroscopic liquid supply unit 45 b through the supply pipe 51. A part of the hygroscopic liquid L in the liquid tank 46 is supplied to the first hygroscopic liquid pipe 61. The hygroscopic liquid L supplied to the first hygroscopic liquid conduit 61 is cooled by the second heat exchanger 32 and supplied again to the hygroscopic liquid supply unit 45a. As described above, the hygroscopic liquid L circulates between the filler 44 and the liquid tank 46, so that the concentration of the hygroscopic liquid L gradually decreases.

  When the hygroscopic liquid L is diluted and regenerated, in addition to taking moisture from the outside air into the hygroscopic liquid L, by directly supplying water to the hygroscopic liquid L, the hygroscopic liquid L can be diluted. Good. The regenerator 40 opens the valve 55 of the water supply pipe 54 and supplies water to the liquid tank 46. Further, the regenerator 40 heats the hygroscopic liquid L by the heating source 53 when the temperature of the hygroscopic liquid L is lowered by the water supply. The hygroscopic liquid L in the liquid tank 46 that has been subjected to the regeneration process returns to the processor 10 through the second hygroscopic liquid conduit 62. The configuration and operation of the first embodiment have been described above.

  The humidity control apparatus 1 according to the first embodiment reduces the opening degree of the damper 18 of the discharge port 13 of the processing machine 10 when performing the dehumidifying process. Thereby, the atmospheric | air pressure in the housing | casing 11 can be raised and the efficiency of a dehumidification process can be improved.

  The humidity control apparatus 1 according to the first embodiment reduces the opening degree of the damper 48 of the intake port 42 of the regenerator 40 when the hygroscopic liquid L is regenerated during the dehumidifying process. Thereby, the atmospheric | air pressure in the housing | casing 41 can be made low and a solution density | concentration can be raised efficiently.

  The humidity control apparatus 1 according to the first embodiment has a simple configuration in which the dampers 18 and 48 are provided at the discharge port 13 of the processing device 10 or the intake port 42 of the regenerator 40, and the atmospheric pressure in the housings 11 and 41. Can be changed.

  When performing the humidification process, the humidity control apparatus 1 according to the first embodiment increases the degree of opening of the dampers 18 and 48 of the processor 10 and the regenerator 40, and naturally adjusts the atmospheric pressure in the casings 11 and 41. Since the pressure is set, the humidification process by the processor 10 and the regeneration process (dilution process) by the regenerator 40 can be prevented.

  In the first embodiment, in both the processor 11 and the regenerator 41, the air taken in from the side surfaces of the casings 11 and 41 passes through the fillers 14 and 44 from the bottom to the top, and the casings 11 and 41. It is discharged from the top surface. Since the hygroscopic liquid L dropped from the hygroscopic liquid supply units 15 and 45 is pushed up from below by air, the time for the hygroscopic liquid L to pass through the fillers 14 and 44 can be increased (the retention time of the hygroscopic liquid L is increased). Yes), efficient gas-liquid contact can be made.

  In addition, when using the humidity control apparatus 1 only for dehumidification, it is good also as a structure which forms a discharge port with large channel resistance (for example, a discharge port with a narrow channel), and does not use a damper.

(Second Embodiment)
FIG. 3 is a diagram illustrating a configuration of the humidity control apparatus 2 according to the second embodiment. The basic configuration and operation of the humidity control apparatus 2 of the second embodiment are the same as those of the humidity control apparatus 1 of the first embodiment. In the humidity control apparatus 2 of the second embodiment, the positions of the fan and the damper are different from those of the humidity control apparatus 1 of the first embodiment. That is, in the second embodiment, the processor 10 has a damper 18 at the intake port 12 and a fan 17 for discharging air to the discharge port 13. The regenerator 40 has a fan 47 for taking air into the intake port 42 and a damper 48 at the discharge port 13.

  FIG. 4A and FIG. 4B are diagrams for explaining the atmospheric pressure in the casings 11 and 41 during the operation of the humidity control apparatus 2 of the second embodiment. Fig.4 (a) shows the time of a humidification process. As shown in FIG. 4A, during the humidification process, the processing machine 10 reduces the opening degree of the damper 18 and lowers the atmospheric pressure in the casing 11 of the processing machine 10. Thereby, since the moisture of the hygroscopic liquid L is easily released into the air, the efficiency of the humidification process can be increased. The regenerator 40 also decreases the opening of the damper 48 and increases the atmospheric pressure in the housing 41 of the regenerator 40. Thereby, since water vapor in the air is easily liquefied, the hygroscopic liquid L can be diluted efficiently.

  FIG. 4B shows the time of dehumidification processing. As shown in FIG. 4B, during the dehumidifying process, the processor 10 increases the opening degree of the damper 18 to make the inside of the housing 11 a natural pressure. As in the case of the humidification process, if the atmospheric pressure in the housing 11 is lowered (see FIG. 4A), moisture is easily released from the hygroscopic liquid L, and the efficiency of the dehumidification process is reduced. When the process is performed, such an inconvenience does not occur by increasing the opening degree of the damper 18. Similarly, the regenerator 40 also increases the opening degree of the damper 48 so that the inside of the housing 41 has a natural pressure. Thereby, the inconvenience that the efficiency of concentration and regeneration of the hygroscopic liquid L by the regenerator 40 is reduced does not occur.

(Third embodiment)
FIG. 5 is a diagram illustrating a configuration of the humidity control apparatus 3 according to the third embodiment. The basic configuration and operation of the humidity control device 3 of the third embodiment are the same as those of the humidity control device 1 of the first embodiment. In the humidity control apparatus 3 according to the third embodiment, the fan 22 is provided instead of the damper 18 of the discharge port 13 of the processor 10, and the fan 56 is replaced with the damper 48 of the intake port 42 of the regenerator 40. have. That is, in the third embodiment, the processor 10 and the regenerator 40 have fans at both the intake ports 12 and 42 and the exhaust ports 13 and 43. These fans 17, 22, 47, and 56 can adjust the force for taking in and discharging air by changing the rotation speed. Note that the fans 17, 22, 47, and 56 may have blades in a shape that makes it difficult for air to pass through when the fans are not rotating.

  FIG. 6A and FIG. 6B are diagrams for explaining the atmospheric pressure in the casings 11 and 41 during the operation of the humidity control apparatus 3 of the third embodiment. Fig.6 (a) shows the time of a dehumidification process. As shown in FIG. 6A, during the dehumidifying process, the processor 10 increases the rotation amount of the fan at the intake port 12 and decreases the rotation amount of the fan 22 at the discharge port 13. Thereby, since the force which takes in air becomes larger than the force which discharges air, the atmospheric | air pressure in the housing | casing 11 of the processing machine 10 becomes high. Thus, when the atmospheric pressure in the housing 11 is increased, the water vapor in the air is easily liquefied, so that moisture is easily absorbed by the hygroscopic liquid L, and the efficiency of the dehumidification process is improved. In addition, since the force to take in air is larger, the amount of air taken in temporarily becomes larger than the amount discharged, but when the inside of the housing 11 is at a constant pressure, the amount of air taken in and the amount discharged Are balanced.

  The regenerator 40 increases the rotation amount of the fan 47 at the discharge port 43 and decreases the rotation amount of the fan 56 at the intake port 42. Thereby, since the force which discharges air becomes larger than the force which takes in air, the atmospheric | air pressure in the housing | casing 41 of the reproducing | regenerating machine 40 becomes low. Thus, when the atmospheric | air pressure in the housing | casing 41 becomes low, it will be in the state from which water | moisture content is easy to discharge | release in air, and the efficiency of the regeneration process which concentrates the hygroscopic liquid L can be improved. In addition, since the force to discharge air is larger, the amount of air discharged temporarily becomes larger than the amount of intake, but when the inside of the housing 41 reaches a constant pressure, the amount of air taken in and discharged The amount is balanced.

  FIG.6 (b) shows the time of a humidification process. As shown in FIG. 6B, during the humidification process, the processor 10 increases the rotation amount of the fan 22 at the discharge port 13 and decreases the rotation amount of the fan 17 at the intake port 12. Thereby, since the force which discharges air becomes larger than the force which takes in air, the atmospheric | air pressure in the housing | casing 11 of the processing machine 10 becomes low. Thereby, it will be in the state from which water | moisture content is easy to be discharge | released in air, and the efficiency of a humidification process will improve.

  The regenerator 40 increases the rotation amount of the fan 56 at the intake port 42 and decreases the rotation amount of the fan 47 at the discharge port 43. Thereby, since the force for taking in air is larger than the force for discharging air, the air pressure in the casing 41 of the regenerator 40 becomes higher. Thereby, the water vapor in the air is easily liquefied, and the efficiency of the regeneration process for diluting the hygroscopic liquid L can be improved.

  As described above, the humidity control apparatus 3 according to the third embodiment controls the amount of rotation of the fans 17, 22, 47, and 56 provided at the intake ports 12 and 42 and the discharge ports 13 and 43. Thus, during the dehumidifying process, the atmospheric pressure in the casings 11 and 41 can be increased to improve the efficiency of the dehumidifying process, and during the humidifying process, the atmospheric pressure in the casings 11 and 41 can be decreased to improve the efficiency of the humidifying process. .

  In the present embodiment, the example in which the atmospheric pressure in the housings 11 and 41 is controlled by making the rotation amount of one fan smaller than the other has been described, but one fan may be rotated in the reverse direction. For example, in the example shown in FIG. 6A, the processor 10 reduces the rotation amount of the fan 22 at the discharge port 13, but rotates the fan 22 at the discharge port 13 in the reverse direction and draws air from the discharge port 13. You may make it take in (discharge negative air). In this case, in order to keep the air flow in a certain direction, the rotation amount of the fan 22 at the discharge port 13 is made smaller than the rotation amount of the fan 17 at the intake port 12.

  Thus, by rotating the fan 22 of the discharge port 13 in the reverse direction and taking in the air, the air is discharged from the discharge port 13 to the outside of the case 11. It becomes high enough to overcome the air intake force by the fan 22. Therefore, the atmospheric pressure in the housing 11 can be further increased.

(Fourth embodiment)
FIG. 7 is a diagram illustrating a configuration of the humidity control apparatus 4 according to the fourth embodiment. The basic configuration and operation of the humidity control device 4 of the fourth embodiment are the same as those of the humidity control device 1 of the first embodiment. In the humidity control apparatus 4 according to the fourth embodiment, the casing 11 of the processing machine 10 has air ports 12 and 13 formed on two side surfaces sandwiching the filler 14. The two air openings are different in size. A fan 17 is attached to the larger air port (hereinafter referred to as “first air port”) 12. The fan 17 can change the rotation direction, and can switch between intake of air into the housing 11 and discharge of air from the housing 11. The smaller air port (hereinafter referred to as “second air port”) 13 has a size that allows a smaller amount of air to be taken in or discharged from the first air port 12. Yes. That is, the second air port 13 has a larger flow path resistance than the first air port 12.

  In the regenerator 40, similarly to the processor 10, a first air port 42 and a second air port 43 having different sizes are formed in the housing 41, and a fan 47 is provided in the first air port 42. It has been. The fan 47 can change the rotation direction, and can switch between intake of air into the housing 41 and discharge of air from the housing 41.

  FIG. 8A and FIG. 8B are diagrams for explaining the atmospheric pressure in the casings 11 and 41 during the operation of the humidity control apparatus 4 according to the fourth embodiment. FIG. 8A shows the time of dehumidification processing. As shown in FIG. 8A, during the dehumidifying process, the fan 17 of the processing machine 10 is rotated in a direction in which air is taken into the housing 11. Thereby, air flows from the first air port 12 to the second air port 13. Since the second air port 13 has a larger flow path resistance than the first air port 12, the atmospheric pressure in the housing 11 becomes higher. Water vapor contained in the air is easily liquefied, and the efficiency of the dehumidification treatment can be improved.

  On the other hand, the fan 47 of the regenerator 40 is rotated in a direction in which air is discharged from the housing 41. Thereby, air flows from the second air port 43 to the first air port 42. Since the second air port 43 has a larger flow path resistance than the first air port 42, the atmospheric pressure in the housing 41 is low. The moisture in the hygroscopic liquid L is easily released into the air, and the efficiency of the regeneration process for concentrating the hygroscopic liquid L can be improved.

  FIG.8 (b) shows the time of a humidification process. As shown in FIG. 8B, during the humidification process, the fan 17 of the processor 10 is rotated in a direction in which air is discharged from the housing 11. Thereby, air flows from the second air port 13 to the first air port 12. Since the second air port 13 has a larger flow path resistance than the first air port 12, the atmospheric pressure in the housing 11 is lowered. The moisture in the hygroscopic liquid L is easily released into the air, and the efficiency of the humidification process can be improved.

  On the other hand, the fan 47 of the regenerator 40 is rotated in the direction of taking air into the housing 41. Thereby, air flows from the first air port 42 to the second air port 43. Since the second air port 43 has a larger flow path resistance than the first air port 42, the atmospheric pressure in the housing 41 becomes higher. Water vapor in the air is easily liquefied, and the efficiency of the regeneration process for diluting the hygroscopic liquid L can be improved.

  As described above, the processor 10 of the humidity control apparatus 4 according to the fourth embodiment controls the rotation direction of the fan 17 provided in the first air port 12, so The pressure inside the body 11 can be increased to improve the efficiency of the dehumidifying process, and the pressure inside the housing 11 can be lowered to improve the efficiency of the humidifying process during the humidifying process. Similarly, the regenerator 40 can perform efficient dilution regeneration or concentration regeneration of the hygroscopic liquid L by controlling the rotation direction of the fan 47.

  Further, in the humidity control apparatus 4 of the fourth embodiment, the first air port 12 and the second air port 13 are formed on the two side surfaces sandwiching the filler 14, so that the humidifying process is also performed. Air flows horizontally during dehumidification. On the other hand, since the hygroscopic liquid L dropped from the hygroscopic liquid supply unit 15 falls downward, the air and the hygroscopic liquid L intersect in the filler 14. Thereby, efficient gas-liquid contact is realizable. Similarly, the regenerator 40 can achieve efficient gas-liquid contact regardless of whether the hygroscopic liquid L is diluted or concentrated and regenerated.

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

  In the above-described embodiment, the first heat exchanger 31 and the second heat exchanger 32 of the heat pump 30 have been described as examples of the configuration for controlling the temperature of the hygroscopic liquid L, but the configuration for controlling the temperature is a heat pump. Not limited to this, an independent heater or cooler may be used. As a heater, you may employ | adopt the structure using the waste heat of another heat source, for example.
