Description

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

  2. Description of the Related Art Conventionally, a wet humidity control apparatus that adjusts air humidity by bringing a hygroscopic liquid such as lithium chloride into contact with air is 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. A wet humidity control device using a hygroscopic liquid utilizes the above properties of the hygroscopic liquid to absorb moisture in the air into the hygroscopic liquid to dehumidify the air, and conversely, to absorb the moisture of the hygroscopic liquid. Release to air to humidify air.

  Wet humidity control equipment is a processing unit (indoor unit) that takes in air and adjusts the humidity to supply air to the humidity control target space, and moisture absorption that is diluted or concentrated in the process of adjusting the humidity of the air by the processing unit And a regenerator (outdoor unit) that regenerates the organic liquid to an appropriate concentration. The processing machine adjusts the humidity by bringing the air taken in the built-in medium into contact with the hygroscopic liquid. The regenerator dilutes the hygroscopic liquid by replenishing the hygroscopic liquid with water, and heats the hygroscopic liquid to release moisture to the outside, thereby concentrating the hygroscopic liquid.

  When performing a dehumidification process using a wet humidity control device, the moisture in the air is absorbed by the hygroscopic liquid by taking in air with a processing machine and bringing it into contact with the hygroscopic liquid of high concentration and low temperature. Is dehumidified and cooled, and supplied to the humidity control target space. As the air is dehumidified and cooled, the hygroscopic liquid absorbs moisture in the air and is diluted to increase the temperature. The hygroscopic liquid that has been diluted to a high temperature is sent from the processor to the regenerator for regeneration. In the regenerator, moisture is released from the diluted hygroscopic liquid, so that the hygroscopic liquid has a high concentration again. Thus, the hygroscopic liquid regenerated (concentrated) by the regenerator is cooled and returned to the processor again.

  When performing humidification using a wet humidity control device, air is taken in by the processor and brought into contact with a low-concentration / high-temperature hygroscopic liquid to release moisture from the hygroscopic liquid into the air. Humidified and heated to supply to the humidity control space. As the air is humidified and heated, the hygroscopic liquid is concentrated by releasing moisture into the air, and the temperature is lowered. The hygroscopic liquid that has been concentrated to a low temperature is sent from the processor to the regenerator for regeneration. In the regenerator, by supplying water to the concentrated hygroscopic liquid, the hygroscopic liquid is again reduced in concentration. Thus, the hygroscopic liquid regenerated (diluted) by the regenerator is heated and returned to the processor again.

  If the air is hot and humid (generally summer in Japan), use a wet humidity control device to bring the air into contact with the cooled hygroscopic liquid so that the dehumidified and cooled air is subject to humidity control. Supply to space. When the air is cold and humid (generally winter in Japan), the humidified and heated air is brought into humidity control by bringing the air into contact with the heated hygroscopic liquid using a wet humidity controller. Supply to space.

  As described above, the wet humidity control apparatus using the hygroscopic liquid supplies air to the humidity adjustment target space and uses the air in the humidity adjustment target space as in the conventional air conditioner, due to its overwhelming humidity adjustment capability. It is not a circulation type that takes in (return air or return air) and regulates humidity, but it can push air to take in air (outside air) outside the humidity control space and supply it to the humidity control space as the desired humidity. .

  As described above, the wet humidity control apparatus has an advantage that fresh external air can be supplied, and a space that requires clean air (for example, a hospital, a care facility, a supermarket, a food factory, an indoor cultivation facility for crops, etc.) Suitable for humidity conditioning. In addition, if there are living organisms such as humans and animals in the humidity control space, oxygen in the air is consumed by the activity of these organisms, carbon dioxide is released into the air, and the carbon dioxide concentration increases. However, the increase in the carbon dioxide concentration can be suppressed by supplying the outside air by pushing the wet humidity control device. Further, since the outside air is supplied to the humidity control target space, the humidity control target space can be set to a positive pressure by adjusting the balance with the exhaust gas, thereby preventing the entry of the draft air.

  Generally, it is known that when the humidity is low, heat dissipation is promoted, and the heat felt is reduced. Therefore, in the case of high temperature and high humidity, dehumidification is performed, but as described above, in the wet humidity control apparatus, when dehumidifying, the outside air is brought into contact with the cooled hygroscopic liquid. Can be supplied to the humidity control space. In this way, the wet humidity control device improves the high-temperature and high-humidity environment by the effect of lowering the sensible temperature by adjusting the latent heat (humidity) and the effect of lowering the sensible heat (temperature) of the supplied air. Space can be provided.

  On the contrary, if the humidity is high, heat divergence is suppressed and the cold feeling is reduced, so humidification is performed by a humidity control device in the case of low temperature and low humidity. As described above, since the wet humidity control apparatus brings the outside air into contact with the heated hygroscopic liquid during humidification, the temperature of the outside air rises. Thus, the wet humidity control apparatus can improve a low-temperature and low-humidity environment into a comfortable space by the effect of adjusting latent heat (humidity) and the effect of adjusting sensible heat (temperature).

  However, in the wet humidity control device, the temperature adjustment is preliminary and the main function is humidity control (dehumidification and humidification). Heating is necessary. In other words, the wet humidity control apparatus can adjust the humidity and reduce the cooling or heating load of the conventional air conditioner.

  For example, in a supermarket, in order to prevent the product from being frosted, the conventional air conditioner excessively cools the air and mixes the air in the store with a large air volume blower for the purpose of dehumidification. As a result, a cold wind was sometimes blown to the customers. On the other hand, by introducing the above-mentioned wet humidity control device and optimizing the humidity, it is possible to maintain a comfortable state even if the temperature is set slightly higher, to prevent frosting on the product, and to cool the product. It will not be too much. Further, the humidity of the air supplied by the wet humidity control apparatus propagates into the space at a very high speed by the principle of the partial pressure difference of water vapor, thereby diffusing and diluting the cold air.

  There are the following documents as prior art related to the present application.

JP 2011-64359 A

  As described above, the wet humidity control device has various effects such as temperature adjustment (assisting air conditioner), forced ventilation, and prevention of frost in addition to humidity adjustment. In order to achieve this, not only optimal setting of operating parameters according to temperature and humidity, but also optimal operation is required, including the method of sealing and exhausting the humidity control target space, and the operating status of the air conditioner used at the same time. .

  In particular, as described above, the humidity of the air supplied by the wet humidity control apparatus propagates into the space at a very high speed by the principle of the partial pressure difference of water vapor, and supplies the conditioned air from one air supply port. By doing so, humidity control of a large-capacity space can be performed. However, this means that the humidity control effect is drastically reduced if there is even one place communicating with the outside air in a wide space.

  If it is a normal air conditioner, an air conditioner is installed in each room or there is an air supply port in each room. For example, when cooling is performed, if each room feels that there is not enough cooling, that room You can take measures such as checking if the window is open and closing it. However, in the wet humidity control apparatus, it is possible to control the humidity of the large volume of the humidity control target space by supplying air from one air supply port. Even if there is a place, even if you do not notice it or feel that the humidity control effect is insufficient, it is not easy to find out where the cause is.

  In addition, with regard to the air condition that can be experienced such as humidity and temperature, it is possible to feel some degree of adjustment effect, but it is difficult to experience the pressure of air and the concentration of carbon dioxide in the air. Even if it is not in the desired state, the user may not notice. For example, even if the humidity control space is appropriately sealed and a desired humidity control effect is obtained, the concentration of carbon dioxide may increase too much due to the presence of many people in the humidity control space. It is difficult to sense such an increase in carbon dioxide concentration.

  Then, an object of this invention is to operate a wet humidity control apparatus appropriately, or to support the proper operation of a humidity control apparatus.

  According to this configuration, even when the wet humidity control device is operating normally, the humidity is extremely low (there may be a part of the humidity control target space communicating with the outside air). If the temperature is extremely low (the air conditioning may be excessively performed without using the cooling assistance effect of the wet humidity controller), the humidity is appropriate but the carbon dioxide concentration is extremely high (conditioning Detects situations where the wet humidity control device is not operating properly and needs to be improved, such as when there are extremely many people in the humidity target space and ventilation may be insufficient it can.

  According to this configuration, the user can know that the humidity control system is not properly operated, and the user can improve the operation himself.

  In the humidity control system, the monitoring device may further detect a situation where the operation of the wet humidity control device needs to be improved based on the operation parameter.

  According to this configuration, by comparing the air condition of the humidity adjustment target space that would be obtained based on the operating parameters with the actual air condition of the humidity adjustment target space detected by the indoor sensor, It is possible to detect a situation where the operation of the humidity control device needs to be improved.

  The humidity control system may further include an outside air sensor that detects the state of the outside air taken into the outside air processing machine, and the monitoring device further includes a state of the outside air detected by the outside air sensor. Based on the detection value, a situation where the operation of the wet humidity control apparatus needs to be improved may be detected.

  According to this configuration, it is possible to obtain the air condition of the humidity control target space that would be obtained by the operation parameter from the relationship between the outside air condition and the operation parameter, and this is detected by the indoor sensor. By comparing with the actual air condition of the humidity control target space, it is possible to detect a situation where the operation of the wet humidity control apparatus needs to be improved.

  In the humidity control system, when the monitoring device detects a situation where the operation of the wet humidity control device needs to be improved, the monitoring device controls the humidity control device to operate the wet humidity control device. The operating parameter to be improved may be specified, and the humidity control device may set the operating parameter specified by the monitoring device in the wet humidity control device.

  According to this configuration, the operation of the wet humidity control apparatus is automatically improved by remote control.

  The humidity control system according to another aspect of the present invention includes an outside air processing machine that takes in outside air, brings the outside air thus brought into contact with a hygroscopic liquid, and supplies the conditioned air to a humidity adjustment target space, and the outside air.

And a history recording device that records a history of detected values.

  According to this configuration, by referring to the history, the operation of the wet humidity control apparatus such as extremely low humidity is not performed properly even though the wet humidity control apparatus is operating, Detect situations that require operational improvements.

  In the humidity control system described above, the air state of the humidity control target space detected by the indoor sensor is the humidity of the air of the humidity control target space, the pressure of the air of the humidity control target space, and the air of the humidity control target space. And / or the carbon dioxide concentration in the air of the humidity control target space.

  By detecting the humidity of the air in the humidity adjustment target space, it is possible to detect a situation that requires improvement, for example, a part of the humidity adjustment target space communicates with the outside air. By detecting the pressure of the air in the humidity adjustment target space, it is possible to detect a situation that requires improvement, such as communication with outside air in a part of the humidity adjustment target space. By detecting the temperature of the air in the humidity control target space, it is possible to detect a situation that requires improvement, for example, in the humidity control target space, such as not effectively utilizing the cooling assistance benefits of the air conditioning device by the wet humidity control device. . By detecting the carbon dioxide concentration in the air in the humidity adjustment target space, for example, it is possible to detect a situation that requires improvement, for example, there are too many people and the carbon dioxide concentration is not sufficiently adjusted by forced ventilation.

  In the humidity control system, the air condition may be the humidity of the air in the humidity control target space and the carbon dioxide concentration in the air of the humidity control target space, and the monitoring device is the indoor sensor. When it is determined that the detected value of the detected humidity of the air is normal and the detected value of the carbon dioxide concentration in the air detected by the indoor sensor is higher than a predetermined threshold value, the humidity control device On the other hand, the operation parameter may be specified so as to maintain the humidity control capability of the wet humidity control apparatus and increase the amount of air supplied to the humidity control target space of the conditioned air, The humidity control device may set the operation parameter designated by the monitoring device in the wet humidity control device.

  According to this configuration, the humidity is normal but the carbon dioxide concentration is abnormally high, that is, there are many people in the sealed humidity control target space, and the adjustment of the carbon dioxide concentration by pushing ventilation of the wet humidity control device It is possible to detect a situation where is insufficient and improve the situation.

The figure which shows the structure of the humidity control system of embodiment of this invention The figure which shows the structure of the wet humidity control apparatus of embodiment of this invention

  Hereinafter, a humidity control system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a humidity control system according to an embodiment of the present invention.

  The humidity control system 100 includes a wet humidity control apparatus 110 including an outside air processing device 111 and a solution regenerator 112. The humidity control system 100 further includes a humidity control device 120 that controls the wet humidity control device 110. The humidity control device 120 sets operating parameters of the wet humidity control device 110 and controls the wet humidity control device 110. The wet humidity control apparatus 110 performs humidity adjustment of the outside air and regeneration of the solution in accordance with the operation parameters set by the humidity control apparatus 120.

  First, the configuration of the wet humidity control apparatus 110 will be described. FIG. 2 is a diagram showing the configuration of the wet humidity control apparatus according to the embodiment of the present invention. The wet humidity control apparatus 110 includes an outside air processor 111 and a solution regenerator 112. The outside air processor 111 takes in outside air, adjusts the humidity by bringing the taken-in air into contact with the hygroscopic liquid L, and supplies the conditioned air to the humidity adjustment target space. The solution regenerator 112 regenerates the hygroscopic liquid L used for humidity control in the outside air processor 111.

  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, when dehumidification is performed by the outside air processing unit 111, the hygroscopic liquid L having a high solution concentration is cooled, and the cooled hygroscopic liquid L and air are brought into contact with each other. Absorb. 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 solution regenerator 112 returns the hygroscopic liquid L to a high solution concentration by desorbing moisture from the hygroscopic liquid L. In the case of humidification, on the contrary, the solution concentration of the hygroscopic liquid L is increased by the humidification process in the outside air treatment device 111. Therefore, the solution regenerator 112 absorbs the moisture in the hygroscopic liquid L so that the solution concentration is increased. Return to low hygroscopic liquid L.

  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 outdoor air processor 111 is an indoor unit that supplies conditioned air to the room, and the solution regenerator 112 is an outdoor unit that regenerates the hygroscopic liquid L by exchanging moisture with the outside air. . FIG. 2 shows an example in which one solution regenerator 112 is connected to one outdoor air processor 111, but a configuration in which one solution regenerator 112 is connected to a plurality of outside air processors 111. Also good. For example, when installing the wet humidity control apparatus 110 in an apartment house, a large supermarket, etc., the outside air treatment device 111 is installed on each floor, and one solution regenerator 112 connected to each outside air treatment device 111 is externally provided. It can also be set as the aspect to install.

  The outside air processor 111 and the solution regenerator 112 are connected by a first hygroscopic liquid conduit 50 and a second hygroscopic liquid conduit 51. The first hygroscopic liquid conduit 50 is a conduit for sending the hygroscopic liquid L from the outdoor air processor 111 to the solution regenerator 112, and the second hygroscopic liquid conduit 51 is an external air treatment from the solution regenerator 112. This is a conduit for sending the hygroscopic liquid L to the machine 111. By circulating the hygroscopic liquid L between the outdoor air processor 111 and the solution regenerator 112 using the first hygroscopic liquid pipe 50 and the second hygroscopic liquid pipe 51, the outdoor air processor 111 The hygroscopic liquid L used can be regenerated by the solution regenerator 112 and returned to the outside air processor 111.

  Next, the configuration of the outside air processor 111 will be described. The outside air processing device 111 includes a housing 11 having an intake port 12 and an exhaust port 13. The intake port 12 is released to the outside air via a duct as necessary, and the exhaust port 13 is released to the humidity adjustment target space via a duct as necessary. The housing 11 forms a processing space for performing a humidity conditioning process on the air. The exhaust port 13 has an exhaust fan 14 and forcibly exhausts air in the processing space. Further, by discharging air from the inside of the processing space, the inside of the processing space becomes negative with respect to the outside, and the outside air 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 as hygroscopic liquid supply ports through which the hygroscopic liquid L is dropped. The hygroscopic liquid L is supplied to the heat exchange coil 16 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. The air taken in from the air inlet 12 is supplied to the heat exchange coil 16 from the side surface (the right side surface in FIG. 2) that opposes the air inlet 12 (in FIG. 2, arrows indicate the flow of air). As a result, the hygroscopic liquid L supplied from above and the air supplied from the right 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.

  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 of the outside air processor 111, a heat exchange coil 36 of the solution regenerator 112, a compressor 22, an expansion valve 23, and a refrigerant pipe 24 connecting 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 passes through the hygroscopic liquid L and the heat exchange coil 16. Whether the hygroscopic liquid L is heated or cooled depends on whether the outside air processor 111 humidifies or dehumidifies the air. That is, when the outside air processor 111 performs humidification, the moisture contained in the hygroscopic liquid L is desorbed and the hygroscopic liquid L and the air are heated so as to be included in the air. Conversely, when the outside air processing unit 111 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.

  The liquid tank 17 stores the absorbent liquid L dropped from the heat exchange coil 16. The outside air processor 111 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 conduit 50 for sending the hygroscopic liquid L in the liquid tank 17 to the solution regenerator 112 is connected to the pipe 18 for sucking the hygroscopic liquid L from the liquid tank 17 through the three-way valve 20. Has been. The three-way valve 20 controls the amount of the hygroscopic liquid L sent to the hygroscopic liquid supply unit 15 of the outside air treatment device 111 and the amount of the hygroscopic liquid L sent to the solution regenerator 112 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 to be reused, and a part of the hygroscopic liquid L flows to the first hygroscopic liquid pipe 50 by the pump 52. Played.

  Next, the solution regenerator 112 will be described. The solution regenerator 112 includes a housing 31 having an intake port 32 and an exhaust port 33. The intake port 32 and the exhaust port 33 are both open to the outside air. The housing 31 forms a processing space in which the hygroscopic liquid L is regenerated.

  The solution regenerator 112 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 outside air processor 111, and a second supply unit 35 b that supplies the hygroscopic liquid L in the liquid tank 37. And have. Each of the first supply part 35a and the second supply part 35b has a plurality of nozzles as hygroscopic liquid supply ports through which the hygroscopic liquid L is dropped. The heat exchange coil 36 has the same configuration as that of the heat exchange coil 16 included in the outside air processor 111. The heat exchange coil 36 constitutes a heat exchanger of the heat pump 21.

  The solution regenerator 112 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. In this way, by circulating the hygroscopic liquid L in the liquid tank 37 using the pipe 38, the solution regenerator 112 repeatedly performs the regeneration process of the hygroscopic liquid L.

  The solution regenerator 112 has a water supply pipe 41 that supplies 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 outside air processor 111 through the second hygroscopic liquid pipe 51. The amount of the hygroscopic liquid L that returns from the solution regenerator 112 to the outside air processor 111 is adjusted by the valve 53. In the present embodiment, the valve 53 controls the amount of the hygroscopic liquid L that is returned to the outside air processor 111 so that the liquid level of the hygroscopic liquid L in the liquid tank 37 is constant. The other configuration of the solution regenerator 112 is the same as that of the outside air processor 111.

  The wet humidity control apparatus 110 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 the reduction of the recooling load in the outside air processor 111 and the reheating load in the solution regenerator 112.

  Hereinafter, the operation of the wet humidity control apparatus 110 will be described in detail by taking the dehumidification process as an example. The operation described below is realized by operating the wet humidity control apparatus 110 according to the operation parameters set by the humidity control apparatus 120.

  When performing dehumidification in the humidity control system 100, the heat pump 21 causes the heat exchange coil 16 to function as an evaporator and the heat exchange coil 36 as a condenser. The liquid tank 17 of the outside air processor 111 contains a hygroscopic liquid L having a high solution concentration.

  The outside air processing device 111 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 outside air processing unit 111 operates the fan 14 to take in outside air from the air inlet 12 and supplies the taken outside 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 outside air processor 111 collects the hygroscopic liquid L that has passed through the heat exchange coil 16 in the liquid tank 17 as described above. The outside air processor 111 sucks the hygroscopic liquid L in the liquid tank 17 through the pipe 18 and supplies the hygroscopic liquid L from the hygroscopic liquid supply unit 15 again. 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 outside air processor 111 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 solution regenerator 112. The humidity control system 100 sends a part of the hygroscopic liquid L sucked out from the liquid tank 17 of the outside air processor 111 to the solution regenerator 112 through the first hygroscopic liquid conduit 50. The amount of the hygroscopic liquid L sent to the solution regenerator 112 is adjusted by the three-way valve 20.

  The solution regenerator 112 regenerates the hygroscopic liquid L having a low solution concentration supplied from the first hygroscopic liquid conduit 50. Specifically, the solution regenerator 112 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.

  Simultaneously with the above operation, the solution regenerator 112 operates the fan 34 to take in the outside air, and supplies the taken-in 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 solution regenerator 112 collects the hygroscopic liquid L that has passed through the heat exchange coil 36 in the liquid tank 37 via the absorbent material 47. The solution regenerator 112 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 solution regenerator 112 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 on which the regeneration process has been performed returns to the outside air processor 111 through the second hygroscopic liquid pipe 51. The hygroscopic liquid L is exchanged with the hygroscopic liquid L toward the solution regenerator 112 by the heat exchanger 54 in the middle of returning to the outside air processor 111, and the temperature of the hygroscopic liquid L decreases. Heretofore, the dehumidifying operation of the humidity control system 100 of the present embodiment has been described.

  Although the dehumidifying operation of the wet humidity control apparatus 110 has been described above, the roles of the outside air processing device 111 and the solution regenerator 112 may be interchanged 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.

  Next, referring to FIG. 1 again, the configuration of the humidity control system 100 of the present embodiment will be described. In addition to the wet humidity control apparatus 110 and the humidity control apparatus 120 described above, the humidity control system 100 includes an operation unit 130 of the humidity control apparatus 120, an indoor humidity sensor 140, an outside air humidity sensor 150, a history recording apparatus 160, The remote monitoring control device 170 and the operation unit 180 of the remote monitoring control device 170 are provided.

  The operation unit 130, the indoor humidity sensor 140, and the outside air humidity sensor 150 are connected to the humidity control device 120. The operation unit 130 is composed of a liquid crystal touch panel, for example. The user can set a target humidity or the like for the operation unit 130. The indoor humidity sensor 140 detects the humidity of the air in the humidity adjustment target space. The outside air humidity sensor 150 detects the humidity of outside air, particularly outside air taken in by the outside air processor 111. The indoor humidity sensor 140 detects the humidity of the air in the humidity adjustment target space as the state of the air in the humidity adjustment target space, and corresponds to the indoor sensor of the present invention. The outside air humidity sensor 150 detects the humidity of outside air as the state of outside air, and corresponds to the outside air sensor of the present invention.

  In the humidity control device 120, the operation parameter is set based on the operation by the operation unit 130 and the detection values of the indoor humidity sensor 140 and the outside air humidity sensor 150. For example, when a humidification process to a predetermined target humidity is instructed by the operation unit 130, the humidity control device 120 sets operation parameters in the wet humidity control device 110 based on the humidity detected by the outside air humidity sensor 150. To do. Specifically, for example, when the humidification process is instructed and the humidity of the outside air is high, the operation parameters are set so as to increase the humidity control capability of the wet humidity control apparatus 110.

  Moreover, the humidity control apparatus 120 adjusts an operation parameter at any time by performing feedback control based on the humidity of the humidity adjustment target space detected by the indoor humidity sensor 140. That is, when the humidity of the humidity adjustment target space approaches the target humidity during operation, the operation parameters are set so that the humidity adjustment capability of the wet humidity adjustment apparatus 110 is lowered. Such operation information of the operation unit 130 (instructed target humidity information, etc.), operation parameters in the humidity control device 120, and detected values of the indoor humidity sensor 140 and the outside air humidity sensor 150 are recorded as a history (log). It is recorded by the history recording device 160 for maintenance and management.

  The above configuration is installed in a place where the wet humidity control apparatus 110 is installed, for example, a hospital, a crop cultivation facility, or the like (hereinafter referred to as “user side”). The humidity control system 100 further includes a remote monitoring control device 170 and its operation unit 180. The remote monitoring control device 170 and its operation unit 180 are installed at a location different from the user side, for example, a management center (hereinafter referred to as “monitoring side”). The remote monitoring control device 170 is connected to the humidity control device 120 and the history recording device 160 via a communication line.

  The history recording device 160 transmits the recorded history to the remote monitoring control device 170 as appropriate. The remote monitoring control device 170 receives the history from the history recording device 160 and monitors the operation status of the wet humidity control device 110. The remote monitoring control device 170 detects a situation that requires operational improvement based on the history. The remote monitoring control device 170 corresponds to the monitoring device of the present invention.

  For communication between the remote monitoring control device 170, the humidity control device 120, and the history recording device 160, an Internet VPN (Virtual Private Network) that realizes a dedicated line via the Internet is used. As will be described later, the remote monitoring control device 170 can also control the operation of the wet humidity control device 110 via the humidity control device 120. On the other hand, in the wet humidity control apparatus 110, in addition to the humidity adjustment effect, it may be used to obtain the effect of adjusting the pressure of the vacant space by pushing ventilation and adjusting the carbon dioxide concentration.

  Such control information for forced ventilation is highly confidential information that affects human health depending on the use environment (for example, when used in a hospital). On the other hand, if a dedicated line is provided between the user side and the monitoring side, the cost increases. Therefore, in the humidity control system 100 of the present embodiment, low cost and high confidentiality are realized by performing communication between the user side and the monitoring side via the Internet VPN.

  The remote monitoring control device 170 is detected by the indoor humidity sensor 140, for example, even though the humidity control device 120 has set a corresponding operation parameter for the outside air humidity detected by the outside air humidity sensor 150. The situation where the humidity of the humidity control target space is not close to the target humidity is detected as a situation that requires improvement of operation. That is, the remote monitoring control device 170 detects the humidity of the humidity adjustment target space that will be obtained based on the temperature and humidity of the outside air detected by the outside air humidity sensor 150 and the operation parameters, and the actual humidity detected by the indoor humidity sensor 140. Compared with humidity, if the difference between the two does not become a predetermined value or less even after a predetermined time has elapsed from the start of operation, it is determined that the situation needs to be improved.

  In this case, the humidity adjustment target space may be in communication with the outside air. When the remote monitoring and control device 170 detects a situation that requires improvement in operation, the operator of the management center contacts the user who has installed the wet humidity control device 110 to improve the operation (for example, through a window). Close).

  The remote monitoring control device 170 can also control the humidity control device 120 by instructing the humidity control device 120 directly to set the operation parameter. In this case, the remote monitoring control device 170 controls the humidity control device 120 based on an instruction input from the operation unit 180 by the monitoring user. As described above, considering that it is difficult for an amateur to understand the operation parameter setting of the humidity control device 120, on the monitoring side, for example, depending on the characteristics of the humidity adjustment target space, a different operation parameter is set for each season. Can be directed.

  Further, when the remote monitoring control device 170 detects a situation that requires improvement of operation, the remote monitoring control device 170 may obtain an operation parameter that can improve the situation and instruct the humidity control device 120 of the operation parameter. For example, even if a predetermined time elapses from the start of operation, the humidity detected by the indoor humidity sensor 140, the target value of humidity (the temperature and humidity of the outside air detected by the outside air humidity sensor 150, and the operation parameters are obtained. If the difference between the humidity and the humidity is not smaller than a predetermined value, the remote monitoring control device 170 obtains an operation parameter for increasing the dehumidifying or humidifying capability, and the remote monitoring control device 170 sends the humidity control device 120 to the humidity control device 120. Operating parameters may be indicated.

  Further, when the remote monitoring control device 170 detects a situation that requires improvement in operation, the remote monitoring control device 170 may transmit an e-mail to that effect to a designated destination. The destination of the e-mail may be an administrator on the user side and / or a staff (serviceman) for maintenance / operation support on the monitoring side.

  The remote monitoring control device 170 may be a personal computer in which a program is installed, and the operation unit 180 may be a display, a keyboard, and a mouse.

  As described above, according to the humidity control system 100 of the present embodiment, the detected values of the indoor humidity sensor 140 and the outside air humidity sensor 150 and the history of operation parameters set by the humidity control device 120 are recorded. Since the situation where the operation of the wet humidity control apparatus 110 needs to be improved is detected based on the history, it is possible to detect a state where the humidity control system 100 is not operated correctly.

  In the above embodiment, the history recording device 160 records the detected values of the indoor humidity sensor 140 and the outside air sensor 107 and the history of the operating parameters of the humidity control device 120. However, the history recording device 160 is omitted. The detected values of the indoor humidity sensor 140 and the outside air sensor 107 and the operating parameters of the humidity control device 120 may be transmitted directly to the remote monitoring control device 170.

  In the above embodiment, the history recording device 160 transmits the history to the remote monitoring control device 170. However, the remote monitoring control device 170 is omitted, and the history recording device 160 simply records the history. There may be. In this case, the maintenance / operation support staff (serviceman) can check the history recorded by the history recording device 160 to improve the operation of the wet humidity control device 110.

  Furthermore, in the above embodiment, the remote monitoring control device 170 as the monitoring device of the present invention is connected to the humidity control device 120 via a communication line, and remotely monitors the operation status of the wet humidity control device 110. However, the monitoring device of the present invention may be incorporated in the humidity control device 120. In this case, the function of the remote monitoring control device 170 described above is provided on the user side. The humidity control device 120 may detect a situation where the operation of the wet humidity control device 110 needs to be improved based on the detection values of the indoor humidity sensor 140 and the outside air humidity sensor 150 and the operation parameters set by the humidity control device 120 itself. . In this case, an alarm device may be provided on the user side, and an alarm may be output by the alarm device when a situation that requires improvement of the operation of the wet humidity controller 110 is detected.

  Further, in the above embodiment, it is necessary to improve the operation of the wet humidity control device 110 based on the operation parameters set by the humidity control device 120 and the detection values of the indoor humidity sensor 140 and the outside air humidity sensor 150. Although the situation is detected, based on the operating parameter set in the humidity control device 120 and the detection value of the indoor humidity sensor 140, a situation where the operation of the wet humidity control device 110 needs to be improved may be detected. Based on only the detection value of the indoor humidity sensor 140, a situation where the operation of the wet humidity control apparatus 110 needs to be improved may be detected. In addition, since the operation parameters set by the humidity control device 120 reflect the detection values of the indoor humidity sensor 140 and the outside air humidity sensor 150, the operation of the wet humidity control device 110 is based only on the operation parameters. You may detect a situation that needs improvement.

  Further, in the above embodiment, the operation parameter set in the humidity control device 120 is used to detect a situation where the operation of the wet humidity control device 110 needs to be improved, but instead of the operation parameter. In the wet humidity control apparatus 110, the operation results of the wet humidity control apparatus 110 such as the amount of air intake and exhaust, the flow rate of the hygroscopic liquid, the temperature and the concentration are detected by a sensor, and the wet operation is performed based on the detected values. A situation where the operation of the humidity control apparatus 110 needs to be improved may be detected. Furthermore, instead of the operating parameters, a situation in which the operation of the wet humidity control apparatus 110 needs to be improved may be detected based on the target humidity input to the operation unit 130 of the humidity control apparatus 120.
