2. Description of the Related Art In recent years, global warming and the ozone layer destruction caused by a large amount of gas emitted from human activities such as carbon dioxide and chlorofluorocarbon and daily life have been reported one after another. Various measures are also being taken internationally to reduce the amount of this occurrence. In particular, regarding Freon gas, the Conference of the Parties to the Framework Convention on Climate Change (COP)
H, which is frequently used in air conditioners,
In addition to CFC refrigerants, HFCs, PFCs, and other alternative chlorofluorocarbons are in the process of being regulated. The desiccant air-conditioning system is not only attracting attention because it is one of the CFC-free air conditioners, but also can use the waste heat that was simply discarded every day. It is promising in the future, and its use is expected to expand more and more.

Various types of desiccant air-conditioning systems of this kind have already been devised.
Japanese Unexamined Patent Publication (Kokai) No. H10-203,086 is known. Hereinafter, the configuration will be described with reference to FIG.

FIG. 20 is a schematic diagram of a conventional desiccant air conditioning system. As shown in FIG. 20, one or more active inorganic powders such as silica gel, zeolite, activated carbon and the like are mixed and processed into a thin sheet to form an active inorganic powder sheet into a honeycomb-shaped hollow structure. Heating means 102 for heating and regenerating the rotor-type suction element 101, and a partition member 10 for partitioning the air flow path.
3. The rotor-type adsorption element 101 is provided with its rotation means 104 and transmission means 105, and the heat recovery sensible heat exchanger 1
06, circulating air cooling means 107, and air sending means 108
Is provided. In this configuration, the rotor-type suction element 101 includes its rotating means 104 and the transmitting means 1.
05 rotates at a constant speed. Further, the rotor-type suction element 101 is provided with a partition member 10 for partitioning the air flow path.
3 allows the air to be dehumidified on the one hand and regenerated by the heating means 102 on the other hand, so that the air can be continuously dehumidified. Here, when dehumidifying, the rotor-type adsorption element 101 chemically adsorbs moisture in the air, so that the dehumidified air not only causes a temperature rise due to heat of adsorption but also adsorbs to the rotor-type adsorption element 101. The element itself acts as a heat exchanger when the moisture is regenerated by the heated air generated from the heating means 102, so that the heat of the heated air is recovered by the dehumidified air and the temperature further rises. Happens. In order to cover this, the air dehumidified by the rotor-type adsorption element 101 is first cooled in the heat recovery sensible heat exchanger 106, and further humidified and cooled by using the latent heat of evaporation of the water in the cooling means 107 for flowing air. You. By supplying the cooled air, the air-conditioned area can be cooled. Conversely, the air from which the rotor-type adsorption element 101 is regenerated contains abundant moisture, so that if it is supplied, the air-conditioning area can be humidified and heated. On the other hand, the rotor-type adsorption element 101 is an active inorganic powder sheet obtained by mixing one or two or more types of active inorganic powders such as silica gel, zeolite, and activated carbon to form a thin sheet.
Is formed in a honeycomb-shaped hollow structure, so that on the dehumidifying side, activated carbon or activated inorganic powder is used to deodorize,
It is possible to add an antibacterial function. Next, the conventional cooling means 107 will be described. FIG. 21A is a schematic view of a cooling coil as a conventional cooling means, FIG. 21B is a schematic view of a water evaporative cooler as a conventional cooling means, and FIG. It is a schematic diagram of a water spray heat exchanger as a means. Conventionally, as shown in each figure, a cooling coil for lowering the temperature of passing air using a chilled water coil or an evaporator using a refrigerant or the like as shown in FIG. As shown in (b), water that blows water to an evaporator that can take a large contact area with air, or that blows water to a place where it is impregnated depending on the material, and deprives the passing air of evaporative latent heat, thereby lowering the temperature. A water spray that evaporates by evaporating water by simply spraying water on the passing air, as shown in FIG. 21 (c), as in the case of a mist, as shown in FIG. Heat exchangers and the like are generally widely known and used.

[0005]

As described above, in the conventional desiccant air-conditioning system, the humidifying means for lowering the temperature of the dehumidified air supplied to the air-conditioning area and achieving cooling is provided with respect to the dehumidified air. In this case, water is simply brought into contact, and the heat of vaporization is used to lower the temperature of air. In such a conventional configuration, the humidifying means does not have an air purifying function, so that molds, bacteria, and the like easily propagate due to moderately high temperature and high humidity. Frequent maintenance such as cleaning of the humidifier is required to prevent scattering of air, and it is necessary to separately provide a filter with dust removal, bacteria elimination and deodorization functions at the outlet of the air conditioning area, etc. There was a problem that it also leads.

Further, the conventional cooling means in which water is simply brought into contact with dehumidified air or only sensible heat is reduced by a chilled water coil or the like cannot be expected to have a Leonard effect, so that negative ions are hardly generated. Even if it occurs, there is a problem in that it cannot be supplied to the air conditioning area because it is blocked by a filter provided at the outlet of the air conditioning area.

[0007] Even if the rotor-type adsorption element has deodorizing and antibacterial functions, if a conventional water evaporation type cooler is used as a humidifier to cool dehumidified air, if maintenance is neglected, the inside of the humidifier or It is also possible that smells and bacteria may be generated later due to the effects of mold and bacteria on the filter and sent to the air-conditioned area, and there was a problem that the precious function could not be used.

Further, when humidification or heating is carried out in a desiccant air conditioning system, the moisture adsorbed on the rotor-type adsorbing element is achieved by desorbing and regenerating the water adsorbed by the heated air and released. Since volatile organic compounds and ammonia are also easily adsorbed, there is a problem that the humidified air on the regeneration side is easily released together with moisture to the air conditioning area side.

The present invention solves such a conventional problem. In addition to air-conditioning an air-conditioning area, the air-conditioning area can be air-cleaned such as dust removal, sterilization, and deodorization at a low cost with easy maintenance.

[0019]

(Embodiment 1) First, a schematic configuration of a desiccant air conditioning system according to the present invention will be described.
FIG. 1 is a schematic configuration diagram of a desiccant air conditioning system according to a first embodiment of the present invention. As shown in FIG. 1, this air conditioning system includes an adsorption element 1, a true humidifier 2 as a humidifier having a water supply unit and a crushing unit, a blower 3, and an air passage for adsorbing moisture in the processing air. , A hot water coil 5 as heating means for producing heated air for regenerating the adsorption element 1, and a regeneration path 6 for forming an air path for desorbing and regenerating the moisture adsorbed by the adsorption element 1. And a blower 3 for sending out the regenerated air after regenerating the adsorption element 1 in the regenerating path 6.
Although not particularly shown, a filter or a rag is provided at the entrance of the adsorption path and the regeneration path so that dust and dust are trapped in advance so as not to enter the inside of the air path.
The adsorption element 1 is formed by processing a material on which at least one adsorbent such as zeolite, silica gel, and activated carbon is supported, and is preferably formed in a honeycomb shape in terms of surface area. The blower 3 is constituted by a sirocco fan or a turbo fan. The hot water coil 5 is constituted by a fin tube type heat exchanger.

Next, the operation will be described. First, as the flow of air on the adsorption side, the processing air 7 to be dehumidified is dehumidified by the adsorption element 1 and introduced into the true humidifier 2 as high-temperature air 8 having a low dew point. In the fresh air humidifier 2, the high-temperature air 8 having a low dew point is humidified and cooled to the wet-bulb temperature, and the supply air 9
Is supplied to the air conditioning area by the blower 3. Next, as the flow of the air on the regeneration side, the regeneration air 10 introduced from the air conditioning area becomes hot air 11 by the hot water coil 5 and is sent to the adsorption element 1. As a heat source of the hot water to the hot water coil 5, hot water as exhaust heat of another heat source, hot water generated by using a boiler, or the like is used. here,
The adsorbing element 1 which has become likely to contain moisture by dehumidifying the air is heated and regenerated, and the adsorbing element 1 is deprived of moisture and discharged as humid air 12. The processing air 7 is introduced from the air conditioning area when the desiccant air conditioning system is of the circulation type, and is introduced from outside the air conditioning area such as outside when the ventilation system is of the ventilation type, and is supplied to the air conditioning area. On the other hand, regeneration air 10
When the desiccant air conditioning system is of a circulation type, air outside the air conditioning area such as an outdoor is introduced. When the desiccant air conditioning system is of a ventilation type, air is introduced from the air conditioning area and discharged outside the air conditioning area such as an outdoor. The air blowing path of the adsorption element 1 is divided into an adsorption path 4 and a reproduction path 6, and the adsorption path 4 and the reproduction path 6 are separated by a partition so as not to be mixed with each other. Here, the processing side can continuously adsorb the moisture in the air by continuously or intermittently rotating the suction side air passage 14 and the reproduction side air passage 15 by rotation as a driving means by the motor 13, while the reproduction side is The water adsorbed on the adsorption element 1 can be continuously regenerated and discharged. FIG. 2 is a schematic diagram in the case where the adsorption path 4 and the regeneration path 6 of the adsorption element 1 are continuously replaced. In the case where the suction path 4 and the regeneration path 6 of the adsorption element 1 are continuously replaced, a circular rotor is generally used for the adsorption element 1 as shown in FIG. Fixed, transmitting the rotation of the motor 13 as a driving means by a pulley and a pulley belt,
This is rotated continuously. On the other hand, FIG. 3 is a schematic diagram of a case where the adsorption path 4 and the reproduction path 6 of the adsorption element 1 are intermittently exchanged. When interchanging the adsorption path 4 and the reproduction path 6 of the adsorption element 1 intermittently, as shown in FIG. 3, the adsorption element 1 has a stacked block shape, and a motor 13 is used as a driving means. Then, the suction path 4 and the regeneration path 8 are intermittently rotated by 90 °. FIG. 2, FIG.
In any method, the rotation speed and the cycle of the motor 13 are adjusted to an optimum speed by the thickness of the suction element 1 in the direction of the air path and the surface wind speed on the surface of the suction element 1.

The adsorbing element 1 may have any shape as long as it absorbs the moisture of the air passing through the adsorbing element 1, and is not limited to those formed by stacking in a honeycomb shape. In FIG. 2, the belt drive method is used when the suction path 4 and the regeneration path 6 of the suction element 1 are continuously replaced. However, the circular rotor is continuously driven by directly driving the motor 13 in combination with the gear. Any method can be used as long as it can be rotated. Further, the rotation angle is set to 90 ° when interchanging the adsorption path 4 and the reproduction path 6 of the adsorption element 1 intermittently. However, any angle may be used as long as the adsorption path 4 and the reproduction path 6 can be switched. . Further, in FIG. 3, a method in which the suction element 1 is directly driven by 90 ° by the motor 13 is used, but any method can be used as long as the suction element 1 can be rotated by a fixed angle, such as by driving using a link mechanism. good. Further, although the hot water coil 5 has been described as the heating means, any heater such as a sheathed heater, a halogen heater, a nichrome wire heater, or the like may be used as long as the temperature can be raised to a temperature at which the adsorption element 1 can be regenerated. It is not limited to the hot water coil 5. For the same reason, the heating means is 1
The configuration is not limited to the type, and may be, for example, a configuration in which an electric heater and a hot water coil 5 are used in combination. In this case, there is also an advantage that when one of the heat sources takes time to raise the temperature of the air, another heat source can cover the heat and keep the regeneration temperature.

Next, the basic configuration of the fresh air humidifier 2 will be described. FIG. 4 is a basic configuration diagram of the true humidifier 2, and FIG.
The humidifier 2 comprises a blower 3 and a water tank 16 which can be removed and supplied by human hands as a water supply means.
Pump 17 and pump 1 for pumping water in the water tank 16
And a nozzle 18 for spraying or spraying water molecules pumped from a pump 17 as crushing means.
And the cylindrical wall 2 which repels water molecules ejected from the nozzle 18
0. The material of the water tank 16 and the cylindrical wall 20 is preferably a member whose charging sequence is a negative member so as not to impair the generation of negative ions described later, and is preferably a lightweight, easy-to-process and environmentally friendly material, For example, polypropylene is used. In addition, pump 1
For example, a centrifugal pump can be used for pumping water, and a hollow cone type nozzle for spraying or spraying water molecules can be used for the nozzle 18, for example. The charging sequence is a series of the amount and charge of static electricity generated for each substance due to friction or the like. FIG. 5 is a charging order table. Exhibited materials are Harada Sangyo Co., Ltd.
"Electrostatic control in the electronics industry"
Because.

Next, the operation will be described. The group of water molecules pumped up from the water tank 16 by the pump 17 is
8 is sprayed or sprayed toward the cylinder wall 20 at high speed. The guide of the amount of water discharged from the pump 17 and the number of nozzles 18 to be installed is an amount capable of humidifying the dehumidified air flowing through the processing path to almost 100% relative humidity. Although fine water molecules are generated at the time of spraying or jetting from the nozzle 18, the water molecules are further crushed by the impact when colliding with the cylindrical wall 20, and a large number of fine water molecules are generated. You. The size of the fine water molecule group is generally 0.5 μm or less. At this time, many negative ions are generated by the Leonard effect or the Simpson effect. On the other hand, the wind flowing through the fresh air humidifier 2 is sucked by the blower 3 from below the fresh air humidifier 2, passes through the fine water molecules generated by the nozzle 18 and the cylindrical wall 20, and passes through the air conditioning area. Dust and chemical substances such as odor components contained in the air are taken into the water molecules when they pass through the fine water molecules in advance, and are discharged as dirt. Dropped to 16 The water in this water tank 16
As a guide, if it is replaced about once a day, it can be used without any hygiene problems. Furthermore, when the true humidifier 2 is used, since dust removal, deodorization, and bacteria removal are performed here, it is not necessary to provide a filter having a dust removal, bacteria removal, or deodorization function at an outlet of an air conditioning area or the like. . The air passing through the fresh air humidifier 2 is dry air that has been dehumidified by the adsorption rotor 1 and is deprived of the latent heat of vaporization of the water molecules when passing through the sprayed or injected water molecules. Instead of increasing the humidity, the dry bulb temperature can be reduced to near room temperature. A true humidifier 2 such that the amount of water molecules sprayed or jetted from the nozzle 18 can be adjusted, such as by adjusting the amount of water discharged from the pump 17.
If the absolute humidity of the air supplied to the air-conditioned area is made smaller than the absolute humidity of the air in the air-conditioned area, the air-conditioned area can be dehumidified. As a result, it is possible to obtain a desiccant air-conditioning system that can perform dehumidification and air purification of the air-conditioning area without separately providing a filter at the outlet, and can supply negative ions to the air-conditioning area.

FIG. 6A is a schematic view of the true humidifier 2 when a pump is not used as a water supply means. In this case, as shown in FIG. 6A, the water supply means uses a water tank 16 and a hollow conical nozzle 21 as in FIG. The conical nozzle 21 simultaneously drives the fans of the blower 3 and simultaneously rotates them by a waterproof motor 22. The method of supplying water to the water tank 16 may be the same as that described with reference to FIG. FIG. 6B is a cross-sectional view of the conical nozzle 21. As shown in FIG. 6B, the conical nozzle 21 has a fine net 23 on the upper surface. The fine net 23 may be made of any material as long as the material has a negative charging order. For example, the fine net 23 is made of polypropylene, which is the same as the material of the cylindrical wall 20 and the like. The mesh interval of the miniaturized net 23 is about several millimeters, for example, 1 to 3
Use the one of about mm. In this way, when the conical nozzle 21 is rotated at a high speed by the motor 22, the water molecules in the tank 16 are sucked up by the conical nozzle 21 and have the centrifugal force of rotation to reduce the size of FIG. Fine water molecules are formed on the net 23 and the lid of the conical nozzle 21. Since the miniaturized net 23 is rotating at the same time as the conical nozzle 21 at a high speed, it plays a role of finely chopping the sucked-up water molecules. Further, the water molecule group collides with the cylindrical wall 20 from the conical nozzle 21 by the centrifugal force of rotation, and a finer water molecule group is generated by the impact force. In such a configuration, the role of the crushing means is such that the cylindrical wall 20 and the miniaturized net 23 play a role.
FIG. 6C is a schematic diagram when the miniaturized net 23 is not built in the conical nozzle 21. The miniaturized net 23 is shown in FIG.
As shown in (c), it is also possible to adopt a configuration in which the conical nozzle 21 is taken out without being built in the conical nozzle 21 and rotated together. In this case, the conical nozzle 21 protrudes by centrifugal force, and the cylindrical wall 20
The finely divided net 23 plays a role of further finely shredding the water molecules that have been finely crushed by the method.

4 and 6 (a) show an example in which the fresh humidifier 2 and the blower 3 are integrated, the air passing through the fresh humidifier 2 is supplied to the air conditioning area. If possible, the blower 3 may be placed anywhere in the processing path 4, and the true humidifier 2 and the blower 3 are not limited to an integrated configuration. Also, a conical nozzle 2
Although the same motor 22 as that of the blower 3 was used for the drive of No. 1, this is a case in which the true humidifier 2 and the blower 3 are integrally formed, and is separate when the blower 3 is separately arranged. It may be driven by a motor, and is not necessarily limited to be driven by the same motor as the blower 3. Also, when the conical nozzle 21 is driven by the same motor 22 as the blower 3, the motor 22 is always arranged between the conical nozzle 21 and the blower 3 as shown in FIG. There is no limitation, and any arrangement and number of motors may be used as long as the conical nozzle 21 and the fan of the blower 3 can be rotated simultaneously. In addition, water tank 1
Water was supplied to the 6 by a method of manual water supply. However, as in the case of a water supply tank in a toilet, a water supply system using a float and a link mechanism was used. An electric valve provided on the water pipe was opened and closed by a water level sensor. Any method may be used as long as the pump 17 can ensure a water supply state, such as a method for automatically supplying water and a method for supplying water by directly connecting the pump 17 to a water pipe. 4 and 6 (a) exemplify a configuration in which water is always stored in the water tank 16, the configuration may be such that water molecules can be continuously sprayed or jetted. The water tank 16 is not necessarily required. In this case, the water supply means may be provided by directly connecting a water pipe and a pump. Further, in the above example, polypropylene was used as the material of the water tank 16 and the cylindrical wall 20 as having a charge order of minus. However, even if the charge order is more than plus, a large amount of negative ions can be supplied. After the time elapses, the charge is electrically neutralized by the negative ions and the negative ions can be supplied, so that the charging sequence is not necessarily limited to the material having the negative polarity. The pump 17 is not limited to a centrifugal pump as long as it can pump water continuously. The nozzle 18 is not limited to a hollow cone type nozzle as long as it can spray or jet water molecules.

Next, the principle of purifying air and generating negative ions by the fresh air humidifier 3 will be described in detail.

FIG. 7 is a schematic view showing the air purifying action of the fresh air humidifier 2 and the principle of generating negative ions. As shown in FIG. 7, the processing air containing dust, dust, odor components, bacteria, and chemical substances is sent from the pump 17 to the nozzle 1.
When passing between the water molecules sprayed or sprayed from 8 and the water molecules further finely pulverized by the cylinder wall 20, the water molecules include dust, dust, odor components, bacteria and chemicals. The substance is taken in. In this way, the treated air is sent out as purified air from which chemical substances such as dust, dust, and odor components and bacteria have been removed. On the other hand, the dirt-containing water molecules are returned to the tank and reused or drained as they are. Further, when the water molecules are sprayed or jetted from the nozzle 18 or when they collide with the cylinder wall 20 to become fine water molecules, a large amount of negative ions are generated by the Leonard effect and the Simpson effect. The negative ions generated here are included in the purified air as described above and sent directly to the air-conditioning area, or large water droplets are separated by providing the steam-water separator 24 as shown in FIG. It is also possible to supply only negative ions and fine water droplets or fine water droplet clusters to the air conditioning area. Further, in this desiccant air-conditioning system, since the processing air is dehumidified by the adsorption element 1, the air has a low dew point, which is lower in absolute humidity or relative humidity than air which normally exists indoors or outdoors. In other words, humidifying such air with a low absolute humidity or relative humidity by the true humidifier 2 is more effective than directly humidifying the outdoor air or indoor air with high absolute humidity or high relative humidity by the true humidifier 2. More water molecules can be humidified into the air, and there is an effect that negative ions, fine water droplets, or fine water droplet clusters can be supplied in a larger amount. Recent research has shown that negative ions, fine water droplets, or fine water droplet clusters provide non-oxidizing effects that prevent rot and corrosion, static elimination effects such as static electricity removal, and physiologically active effects such as refreshing and relaxing effects. Thus, if the true humidifier 2 is used in the desiccant air-conditioning system as described above, not only can air purification be performed, but also more negative ions can be supplied to the air-conditioning area, making the air-conditioning area a more comfortable space. You can do it.

Next, an example of the structure of the steam separator 24 shown in FIG. 7 will be described. FIG. 8A is a schematic configuration diagram of the steam separator 24 as a component. As shown in FIG. 8 (a), the steam separator 24 is composed of a number of openings and a shielding plate, and it is more preferable to use a material whose charging sequence is less than that of the true humidifier 2, as in the case of the fresh air humidifier 2. , For example, polypropylene.

Next, the operation and effect of the steam separator 24 will be described. FIG. 8B is a schematic diagram illustrating the effect of the steam separator 24. As shown in FIG. 8B, the steam-water separator 2
4 is to pass air sent in a state containing water molecules of various sizes generated by the crushing means,
At the same time, the direction of air passage is changed by the resistance of the shielding plate, and at the same time, only large water molecules and water droplets contained in the air are separated. The air that has passed through the steam separator 24 becomes air containing only negative ions, fine water droplets, or fine water droplet clusters, and can be supplied from the blower 3 to the air conditioning area. FIG. 9 is a schematic diagram in the case where the steam separator 24 is configured only with an air passage. The material in this case is the same as that in FIG. 8A or 8B. As shown in FIG. 9, the processing air is introduced from above the position of the nozzle 18 to form a downward airflow, passes through a group of sprayed or injected water molecules, and then passes through the steam-water separator 24 as an upward airflow. If the air passage and the water / water separator 24 are integrally formed as described above, while passing through the water / water separator 24 after changing from a descending airflow to an ascending airflow, large water molecules and water droplets contained in the air Only gravity is naturally separated by gravity, which can be returned to the water tank 16. If the steam-water separator 24 is used in the desiccant air-conditioning system as described above, only large water molecules can be separated, and air containing negative ions, fine water droplets or fine water droplet clusters can be efficiently supplied to the air-conditioning area, The air-conditioned area can be made a more comfortable space.

In the case where the steam separator 24 is used as a component, an example in which the steam separator 24 is composed of a large number of openings and a shielding plate has been described. However, it includes water molecules of various sizes generated by the crushing means. It is only necessary to be able to separate large water molecules and water droplets contained in the air when passing the air sent in the air, and the shape and mechanism are limited to those shown in FIG. Not something. Further, as an example in which the steam separator 24 is composed of only the air path, an air path configuration as shown in FIG. 9 is taken as an example. However, in a state in which water molecules of various sizes generated by the crushing means are included. It is only required that large water molecules and water droplets contained in the air when passing the sent air can be separated, and the present invention is not limited to this air path configuration.

Next, FIG. 10 is a schematic configuration diagram in the case where the fresh air humidifier 2 is provided with a sterilizing means. As shown in FIG.
In the water tank 16 of the fresh air humidifier 2 shown in FIG. 4, as a sterilizing means, preferably a low input, a high sterilizing effect, and no influence on the air conditioning area, for example, a UV sterilizing lamp 25 for irradiating ultraviolet rays Are arranged so as to be able to irradiate.

Next, the operation and effect will be described.
As described with reference to FIG.
From step 8, chemical substances such as dust, dust, and odor components, which are taken in by the water molecules sprayed or jetted, and bacteria are taken in. Therefore, if time passes, bacteria may gradually grow in the water tank 16, and the inside of the water tank 16 and the inside of the true humidifier 2 may become unsanitary. For this reason,
Usually, maintenance such as frequent cleaning of the inside of the humidifier 2 and the water tank 16 is required. However, if a UV germicidal lamp 25 is provided as a germicidal means so that irradiation can be performed, bacteria in the water tank 16 can be radiated. Can be killed and the inside of the water tank 16 can be kept hygienic, so that maintenance such as cleaning becomes easy. In addition, the method of sterilizing by UV irradiation with the UV germicidal lamp 25 exerts its effect only inside the tank, such as means for sterilizing using a chemical substance or the like.
There is no need to worry about scattering to the air conditioning area. By using the UV germicidal lamp 25 in this way, the growth of bacteria in the fresh air humidifier 2 can be suppressed, the inside of the fresh air humidifier 2 can be kept clean at the same time, and there is no fear of scattering to the air conditioning area. A desiccant air conditioning system that facilitates maintenance of the humidifier 2 can be obtained.

In FIG. 10, the sterilizing means is provided in FIG. 4 as an example. However, when the true humidifier 2 is provided with the water tank 16, all of them can be used. It is not limited.

Next, FIG. 11 is a schematic configuration diagram in a case where the fresh humidifier 2 is provided with a removing means for removing impurities present in the water molecule group. As shown in FIG. 11, when the fresh humidifier 2 has the water tank 16 shown in FIG. 4, a hollow fiber filter 26 is used as a removing means for removing impurities, and the water supply means of the fresh humidifier 2 is used. Between the water tank 16 and the pump 17.

Next, the operation and effect will be described.
As in the description of FIG. 10, chemical substances such as dust, dust, and odor components and bacteria are taken in the water tank 16. When water is supplied to the pump 17 from the water tank 16, the water is filtered by the hollow fiber filter 26. Is done. Hollow fiber filter 2
6 has a hollow shape one by one, and 1
It has a structure in which microscopic holes smaller than a micron are innumerably opened. Dust, dust, bacteria and the like sucked from the water tank 16 can be captured and removed when passing through the water tank 16, and clean water molecules can be used in the true humidifier 2. . Further, it is known that the number of negative ions generated by the fresh air humidifier 2 is improved as the water quality is better. If the hollow fiber filter 26 is attached to improve the water quality and the water is sprayed or jetted from the nozzle 18, the negative ions are generated. And the number of negative ions can be increased, and more negative ions can be supplied to the air conditioning area. By using the hollow fiber filter 26 in this way, it is possible not only to prevent bacteria in the fresh air humidifier 2 from circulating in the fresh air humidifier 2 but also from scattering to the air conditioning area. By always supplying water molecules of good quality, the amount of negative ions generated by the Leonard effect and the Simpson effect is improved, and a desiccant air conditioning system capable of supplying more negative ions to the air conditioning area can be obtained.

In FIG. 11, the hollow fiber filter 26 is used as a removing means for removing impurities present in the water molecule group of the fresh air humidifier 2; however, in addition to chemical substances such as dust, dust, and odor components, bacteria It is only necessary to be able to remove chemical substances such as odor components by using countless holes on the surface, for example, if granular activated carbon or ceramic particles are used, chlorine or trihatamelon etc. They can be removed, and they are not limited to the use of the hollow fiber filter 26, such as using them alone or using them together with the hollow fiber filter 26. Further, even when water molecules are directly introduced into the pump 17 from a water pipe or the like without using the water tank 16 as in the example of FIG. 11, the removing means is disposed between the water pipe as the water supply means and the pump 17. The configuration is not limited to the configuration including the water tank 16.

As described above, in this embodiment, the dehumidified air continuously supplied into the air-conditioning area using the adsorption element 1 that reversibly adsorbs and desorbs the moisture in the air is used as the pure air humidifier 2. By supplying fine water molecules finely crushed in the inside, it is possible to take in chemical substances and bacteria such as dust, dust and odor components contained in the air and then supply them to the air conditioning area, so air conditioning is inexpensive A desiccant air conditioning system capable of supplying purified air while dehumidifying the area is obtained.

Further, the dehumidified air continuously supplied into the air-conditioning area using the adsorbing element 1 which reversibly adsorbs and desorbs the moisture in the air is supplied to a fine humidifier 2 which is finely crushed. By supplying water molecules, a large amount of negative ions due to the Leonard effect and the Simpson effect can be generated and supplied to the air-conditioning area. Therefore, the desiccant that can simultaneously supply the negative ions while dehumidifying the air-conditioning area. An air conditioning system is obtained.

In addition, of the water molecules generated by the crushing means, the structure provided with the steam-water separator 24 for separating water droplets allows only large water molecules to be separated, resulting in a negative effect having a physiologically active effect. A desiccant air conditioning system capable of efficiently supplying air containing ions, fine water droplets, or fine water droplet clusters to the air conditioning area is obtained.

Further, a UV germicidal lamp 25 is used as a germicidal means for sterilizing bacteria that grow in the true humidifier 2 as humidifying means.

FIG. 12 is a basic schematic diagram of a desiccant air conditioning system according to a second embodiment of the present invention. As shown in FIG. 12, this air conditioning system regenerates the adsorption element 1, a fresh air humidifier 2, a blower 3, an adsorption path 4 for forming an air path for adsorbing moisture in the processing air, and an adsorption element 1. The heating water coil 5, the regeneration path 6 that forms an air path for desorbing and regenerating the moisture adsorbed by the adsorption element 1, the adsorption path 4 and the regeneration path 6, and the flow of air flowing through the adsorption path 4 and the regeneration path 6 are observed. Sensible heat exchanger 27 for heat exchange
And a cooler 28 for cooling the regeneration air to near the wet bulb temperature.
And a blower 3 in the regeneration path 6 for sending out the regeneration air after the adsorption element 1 has been regenerated. Although not particularly shown, a filter or a dust is provided at the entrance of the adsorption path 4 and the regeneration path 6 so that large dust and dust are trapped here so as not to enter the inside of the apparatus. Specifically, the sensible heat exchanger 27 is made of a rotary sensible heat exchanger, and is preferably made of a rust-resistant material such as aluminum or stainless steel.
A rotary sensible heat exchanger having a honeycomb-shaped rotor inside is used. Next, as the cooler 28, for example, a cooling coil which is a fin tube type heat exchanger is used.

Next, the operation will be described. First, as the flow of air on the adsorption side, the treated air 29 to be dehumidified is dehumidified by the adsorption element 1 as in the first embodiment, and is subjected to sensible heat exchange in the sensible heat exchanger 27 as high-temperature air 30 having a low dew point.
After the air is purified and humidified and cooled in the true humidifier 2, it is supplied to the air conditioning area. Next, as the flow of the air on the regeneration side, the regeneration air 33 is first cooled in the cooler 28. The cooled air 34 is supplied to the processing air 30 in the sensible heat exchanger 27.
After the sensible heat exchange with the hot water coil 5, the hot air is introduced into the hot water coil 5 as heat recovered air 35, and is sent to the adsorption element 1 by the hot water coil 5. The high-temperature air 36 heats and regenerates the adsorbing element 1, which is likely to contain moisture by dehumidifying the air, deprives the adsorbing element 1 of water, and is discharged as humid air 37. Here, the processing air 29 and the regeneration air 33
Is introduced in the same manner as described in the first embodiment. Next, the ventilation path of the sensible heat exchanger 27 is divided into an adsorption path 4 and a regeneration path 6 as in FIG. 2, and the adsorption path 4 and the regeneration path 6 are partitioned by a partition so as not to be mixed with each other. The driving means is also continuously rotated at a constant speed by the motor 13 as in FIG. 2, and the suction path 4 and the reproduction path 6 are interchanged. Since the processing air 29 that has become high-temperature air as a result of dehumidification by the adsorption element 1 flows through the adsorption path 4 of the sensible heat exchanger 27, high temperature is stored in the sensible heat exchanger 27 while sensible heat is stored. Since the regeneration air 33 cooled by the cooler 28 flows through the regeneration path 6 of the heat exchanger 27, the sensible heat exchanger 2
As a result, the sensible heat exchanger 27 rotates to achieve both sensible heat exchanges. That is, the processing air 30 is cooled only by its sensible heat,
As a result of approaching the dry-bulb temperature of No. 4, the specific enthalpy value is reduced, and the desiccant air-conditioning system can be cooled, thereby improving the air-conditioning capacity. On the other hand, the regeneration air 34 is
As a result of recovering the heat of step 4 and approaching the dry-bulb temperature of the processing air 30, the required input required by the hot water coil 5 can be reduced. As a result, the sensible heat exchange of the sensible heat exchanger 27 can improve the coefficient of performance of the entire desiccant air conditioning system. Furthermore, in the system of the present embodiment, a rotary heat exchanger is used as the sensible heat exchanger 27, and the sensible heat exchange efficiency of the sensible heat exchanger 27 can be changed by adjusting the number of rotations. When the cooling capacity of the sensible heat exchanger 27 can be adjusted and the rotation speed of the sensible heat exchanger 27 is set to zero, the sensible heat exchange efficiency of the sensible heat exchanger 27 becomes zero.
It is also possible to make the system completely equivalent to. In this way, a configuration is provided that includes a sensible heat exchanger 27 that exchanges sensible heat between the air dehumidified by the adsorption element 1 and heated to a high temperature by the heat of adsorption, and the regeneration air flowing through the hot water coil 5 as a heating unit. By doing so, the heat of adsorption heat is recovered in the regenerated air, so that the required input to the hot water coil 5 can be reduced. As the specific enthalpy value decreases, cooling of the air conditioning area becomes possible, and the cooling capacity is improved in accordance with the sensible heat exchange efficiency of the sensible heat exchanger 27, so that a desiccant air conditioning system having an excellent coefficient of performance can be obtained.

Although a rotary sensible heat exchanger is used as the sensible heat exchanger 27, any sensible heat exchange between the processing air 30 and the regeneration air 34 can be used. If it is a metal, it is preferably made of a rust-resistant material, such as aluminum or stainless steel, as in the drive type, and if it is a non-metal, it is a non-moisture permeable resin, for example, a plate fin heat exchanger made of polystyrene or the like. But it is good. Also, a fin tube type cooling coil has been described as an example of the cooler 28, but any means can be used as long as it can reduce the dry bulb temperature of the regeneration air 33. , A water spray heat exchanger, and a true humidifier 2 may be used. Also, the cooler 28 has a dry bulb temperature of the regeneration air 33 to some extent,
For example, when the temperature is lower than 30 ° C., the specific enthalpy of the processing air 31 can be sufficiently reduced in the sensible heat exchanger 27, and therefore, it is not necessary.

As described above, in this embodiment, the sensible heat exchange between the air dehumidified by the adsorption element 1 and heated to a high temperature by the heat of adsorption and the regenerated air flowing through the hot water coil 5 as the heating means. With the configuration including the exchanger 27, the heat of the adsorption heat is recovered to the regenerated air, so that the necessary input to the hot water coil 5 can be reduced. Since only the heat is cooled and the specific enthalpy value is reduced, the air conditioning area can be cooled, and the cooling capacity is improved according to the sensible heat exchange efficiency of the sensible heat exchanger 27, so that the coefficient of performance is excellent. A desiccant air conditioning system is obtained.

(Embodiment 3) In this embodiment, unless otherwise specified, the same parts as those described above are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

FIG. 13 is a basic schematic diagram of a desiccant air-conditioning system according to a third embodiment of the present invention. As shown in FIG. 13, this air conditioning system regenerates the adsorption element 1, the fresh air humidifier 2, the blower 3, the adsorption path 4 that forms an air path for adsorbing moisture in the processing air, and the adsorption element 1. The heating water coil 5, the regeneration path 6 that forms an air path for desorbing and regenerating the moisture adsorbed by the adsorption element 1, the adsorption path 4 and the regeneration path 6, and the flow of air flowing through the adsorption path 4 and the regeneration path 6 are observed. Sensible heat exchanger 27 for heat exchange
A fresh air humidifier 2 as a humidifier for humidifying the regenerated air in the regeneration path 6 after regenerating the adsorption element 1;
A blower 3 for sending out the regenerated air after the adsorbing element 1 is regenerated in the regenerating path 6. Although not particularly shown, a filter or a dust is provided at the entrance of the adsorption path 4 and the regeneration path 6 so that large dust and dust are trapped here so as not to enter the inside of the apparatus.

Next, the operation will be described. First, as the flow of the air on the adsorption side, the processing air 38 to be dehumidified is dehumidified by the adsorption element 1 as in the first embodiment, and is subjected to sensible heat exchange in the sensible heat exchanger 27 as high-temperature air 39 having a low dew point. The air is exhausted outside the air conditioning area as 40. Next, as the flow of the wind on the regeneration side, the regeneration air 41 is supplied to the sensible heat exchanger 27.
After the sensible heat exchange with the processing air 39, the sensible heat of the processing air 39, which has become high temperature due to the heat of adsorption, is recovered and the recovered air
The hot water is introduced into the hot water coil 5 and turned into high-temperature air 43 by the hot water coil 5 and sent to the adsorption element 1. The hot air 43 is
The adsorbing element 1, which is likely to contain moisture due to dehumidification of the air, is heated and regenerated, deprives the adsorbing element 1 of water and becomes hot and humid air to be introduced into the fresh air humidifier 2. The humidified air 44 humidified by the true humidifier 2 is supplied to the air-conditioning area as it is, so that the air-conditioning area can be humidified or heated. When the desiccant air-conditioning system is of a circulation type, the processing air 38 is supplied from outside the air-conditioning area such as outside.
In the case of a ventilation type, the air is introduced from the air conditioning area and exhausted to the outside of the air conditioning area such as the outside. On the other hand, the regeneration air 41
When the desiccant air-conditioning system is of a circulation type, air is introduced from an air-conditioning area, and when the system is of a ventilation type, air is introduced from outside the air-conditioning area, such as outdoors, and finally supplied to the air-conditioning area as air for humidification or heating. On the other hand,
Due to its structure, the adsorbing element 1 has a property of adsorbing chemical substances such as odor components when the processing air 38 is dehumidified. That is, when humidification or heating is performed in the desiccant air-conditioning system, if these substances are contained in the processing air 38, the adsorbing element 1 that adsorbs these substances generates the regeneration air 4.
When the water is regenerated by the fuel cell 3 and the water is released, there is a risk that these chemical substances may be discharged together with the air-conditioned area.
Then, the air that has passed through the adsorption element 1 is converted into a true humidifier 2.
To be introduced. By doing so, chemical substances such as odor components, dust, and dust contained in the air passing through the adsorption element 1 can be removed in the true humidifier 2 to purify the air. Since the air that has been regenerated is very humid and almost saturated, there is no concern that water molecules will lose latent heat of vaporization when passing through the fresh air humidifier 2 and after passing through the fresh air humidifier 2 The dry-bulb temperature of the regeneration air 44 does not decrease so much. In addition, since negative ions are generated by the Leonard effect and the Simpson effect in the true humidifier 2 without any change, the negative ions can be supplied to the air-conditioning area.

As described above, in this embodiment, the humidified air continuously supplied into the air-conditioning area by using the adsorption element 1 which reversibly absorbs and desorbs moisture in the air is used as a true humidifier. By supplying fine water molecules finely crushed in 2, chemicals and bacteria such as dust, dust and odor components contained in the air can be taken and then supplied to the air conditioning area, so it is inexpensive A desiccant air conditioning system capable of supplying purified air while humidifying or heating the air conditioning area is obtained.

Further, the humidified air continuously supplied into the air-conditioning area using the adsorbing element 1 which reversibly adsorbs and desorbs moisture in the air is supplied to the air humidifier 2 where the humidified air is finely crushed. By supplying water molecules, a large amount of negative ions due to the Leonard effect and the Simpson effect can be generated and supplied to the air-conditioning area. A possible desiccant air conditioning system is obtained.

(Embodiment 4) In this embodiment, unless otherwise specified, the same parts as those described above are designated by the same reference numerals, and the description thereof will be omitted. Only different parts will be described.

Here, various performances of the fresh air humidifier 2 described in the first embodiment will be described with reference to experimental results. First, the dust removal performance of the true humidifier 2 will be described.
FIG. 14 is a graph showing an experimental result regarding the dust removal performance of the true vessel humidifier 2 alone. When dust is generated by hitting a futon-like cloth in a room, the room is agitated with a fan, and after a while, the true humidifier 2 is operated in the inside air circulation at a rate of 50 ventilations / hour. Elapsed time on the horizontal axis,
The vertical axis shows the number of dust per unit volume measured by the particle counter for each size of dust. As can be seen from the results of the graph, the dust removal performance of the humidifier 2 is
It can be seen that the larger the dust, the higher the dust, and if the size is 0.5 μm or more, the number is smaller than the number of dust before dust is generated. In addition, even if the size is 0.5 μm or more, the number is hardly changed by natural attenuation, but the dust is slightly removed.

Next, the deodorizing performance of the fresh air humidifier 2 will be described. FIG. 15A is a graph showing an experimental result on the ammonia deodorizing performance of the fresh air humidifier 2 alone, and FIG.
FIG. 5 (b) is a graph showing an experimental result on the acetic acid deodorizing performance of the fresh air humidifier 2 alone. FIG. 15 (c) is a graph showing an experimental result on acetaldehyde deodorizing performance of the fresh air humidifier 2 alone. These graphs show that each gas is generated using cigarettes in a closed space room,
This is a case where the fresh air humidifier 2 is operated by internal air circulation at a rate of 3.8 times / hour of ventilation, and the elapsed time is plotted on the horizontal axis, and the odor concentration measured by the gas detection tube is plotted on the vertical axis. The odor remaining rate when the value before the operation of the vessel 2 is set to 1 is shown. As a comparative reference, the deodorizing performance of the humidifier 2 was compared with that of the true humidifier 2 during natural attenuation and when a filter air cleaner of a certain company was operated. As can be seen from any of the graphs, it can be seen that the true humidifier 2 has a significantly better deodorizing ability than the natural attenuation and filter type air cleaner. In addition, similar results were obtained with formaldehyde, indicating that the Shinki humidifier 2 was very effective in removing chemical substances such as odor components and VOCs.

Next, the sterilization effect by the true humidifier 2 and the UV
The germicidal effect of the germicidal lamp 25 will be described. FIG. 16 is a table showing the results of experiments on the disinfection effect by the true humidifier 2 and the disinfection effect by the UV germicidal lamp 25. For the experiment, a fresh air humidifier 2 equipped with a UV germicidal lamp 25 was prepared in a clean room, and tap water dechlorinated by a filter was put in a water tank 16. Further, as experimental conditions, dechlorinated tap water was operated for 30 minutes immediately after being put on the day, left for 4 days, operated for 30 minutes, and left for 5 days, and then left for 30 days.
The number of bacteria in the tank before and after the operation of the fresh air humidifier 2 and the number of airborne bacteria in the room were measured before and after the operation. In addition, when the dechlorinated tap water was operated on the same day, the number of bacteria in the tank before and after the operation of the true humidifier 2 was similarly determined when the UV germicidal lamp 25 was turned ON and OFF, The number of suspended bacteria in the room was measured. In addition, as bacteria measured, bacteria resident in the outside air (general bacteria) were measured. In particular,
For measuring bacteria in tank water, 1m tank water on Petri film
l, and the number of suspended bacteria was measured using an RCS sampler, which was operated at a maximum suction volume of 320 liters for 8 minutes. After culturing at 37 ° C for 48 hours, the cells were further cultured at room temperature for 5 days. And the final number of bacteria. U
Regarding the effect of the V germicidal lamp 25, as shown in FIG.
It can be seen that the number of bacteria in the tank after the operation when the V germicidal lamp 25 was turned off was 2050, while the number of bacteria in the tank after operation was 0 when the V sterilization lamp 25 was turned on. The UV germicidal lamp 25 is very effective in maintaining good sanitary conditions in the tank, since the bacterial count in the tank after leaving it for 4 or 5 days using dechlorinated tap water is very large. You can see that there is. On the other hand, regarding the disinfection performance of the fresh air humidifier 2, the fresh air humidifier
Although a very small amount of bacteria was detected in the air in the clean room before the operation, the humidifier 2 was not detected at all after the operation. From this, it can be seen that the fresh air humidifier 2 is very excellent in sterilization performance.

Next, the relationship between the number of negative ions generated by the fresh air humidifier 2 and water quality will be described. FIG. 17 is a true humidifier 2
Is a graph showing the relationship between the quality of water used and the number of generated negative ions. The experimental conditions were as follows. In a closed room having a size of about 3 tatami mats, the humidifier 2 was operated for one hour, and the number of negative ions in the room was measured with a negative ion counter. For the kind of water used for the operation of the sane humidifier 2, tap water, dechlorinated tap water, ion-exchanged water, and ultrapure water are prepared, and each electric low efficiency is measured in advance. In the operation of No. 2, the water temperature was unified to 12 ° C. and the number of negative ions was measured under the same conditions. This is plotted on the abscissa with the electric low efficiency and the ordinate with the number of negative ions. As can be seen from the results, the number of negative ions generated in the fresh air humidifier 2 is almost proportional to the water quality, more specifically, the electric low efficiency of the water used. From this, it can be seen that if the quality of the water used for the fresh air humidifier 2 is good, the number of generated negative ions can be increased, and the mounting of the hollow fiber filter 26 in Example 1 is very effective.

(Embodiment 5) In this embodiment, unless otherwise specified, the same parts as those described above are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

Here, the usefulness of the desiccant air-conditioning system described in the first embodiment when the true humidifier 2 is used will be described with experimental results. FIG. 18 is a schematic configuration diagram of an experiment when the true humidifier 2 is used in the desiccant air conditioning system. The configuration of the desiccant air-conditioning system is the same as that of the first embodiment, and detailed description of the configuration and the like is omitted.
In the experimental configuration, as shown in FIG. 18, a 1 cubic meter box 46 was prepared in a constant temperature room 45 that could be adjusted to a constant temperature and humidity, and a desiccant air-conditioning system equipped with the true humidifier 2 was connected. Further, a negative ion counter 47 is set in the 1 cubic meter box 46. The processing air 48 sucked from the constant temperature chamber is supplied as processing air 49 to the 1 cubic meter box 46 via the adsorption element 1 and the true humidifier 2. On the other hand, the regeneration air 50 is also sucked in from the constant temperature chamber, is heated here by the electric heater 5 as a heating means, and then regenerates the adsorption element 1 and is exhausted as regeneration air 51 into the constant temperature chamber. 1 cubic meter box 46
Has many holes, and the pressure difference between the inside and the constant temperature chamber is 0
It was configured to be. Specifically, a nichrome wire heater was used for the electric heater 5. Next, as experimental conditions, first, the vacuum humidifier 2 was operated in a state where the operation of the adsorption element 1 and the electric heater 5 was turned off and the dehumidification capacity was set to 0,
The number of negative ions in one cubic meter box 46 was measured by negative ion counter 47. Next, with the operation of the adsorption element 1 and the electric heater 5 turned ON and the dehumidification capacity at the maximum of about 5 liters per hour, the true humidifier 2 was operated, and the relative humidity in the 1 cubic meter box 46 when the dehumidification amount was 0 hour. While adjusting the humidification amount so as to be the same as the humidity, the number of negative ions in the 1 cubic meter box 46 was measured by the negative ion counter 47, and the number of negative ions was compared with the case where the dehumidification amount was 0. FIG. 19 is a table showing the results of experiments in Example 5. As shown in this table, when the ratio of the number of negative ions measured when the operation of the adsorption element 1 and the electric heater 5 was turned off was set to 100, the adsorption element 1 and the electric heater 5 were turned on and the dehumidified air was collected. When humidification was performed by the air humidifier 2, the ratio of the number of negative ions increased by about 25% to 125. As described in the first embodiment, when the air is dehumidified by the adsorption element 1, the air has an absolute humidity or a relative humidity lower than the air when the air is not dehumidified. That is, humidifying the air having such a low absolute humidity or relative humidity by the true humidifier 2 is more effective than directly humidifying the outdoor air or indoor air having a high absolute humidity or relative humidity by the true humidifier 2. This is considered to be because it is possible to humidify more and to supply a larger amount of negative ions, fine water droplets or fine water droplet clusters generated in the true humidifier 2.

As is apparent from the above embodiment, according to the present invention, the dehumidified air continuously supplied into the air-conditioning area using the adsorbing element for reversibly adsorbing and desorbing moisture in the air can be obtained. By supplying finely crushed fine water molecules, chemical substances and bacteria such as dust, dust and odor components contained in the air are taken in the fine water molecules and removed, and then supplied to the air conditioning area Therefore, it is possible to obtain a desiccant air conditioning system capable of supplying purified air while dehumidifying the air conditioning area at low cost.

Further, by supplying fine water molecules finely crushed to the humidified air continuously supplied into the air conditioning area by using an adsorption element which reversibly adsorbs and desorbs moisture in the air. Chemical substances and bacteria such as dust, dust and odor components contained in the air can be taken into fine water molecules and removed before being supplied to the air-conditioning area. At the same time, a desiccant air conditioning system capable of supplying purified air is obtained.

Further, by supplying fine water molecules finely crushed to dehumidified air continuously supplied into the air conditioning area by using an adsorption element which reversibly absorbs and desorbs moisture in the air. Since negative ions due to the Leonard effect and the Simpson effect can be generated and supplied to the air-conditioning area, a desiccant air-conditioning system that can supply the negative ions while dehumidifying the air-conditioning area can be obtained.

Further, fine water molecules finely crushed are supplied to the humidified air which is continuously supplied into the air conditioning area by using an adsorption element which reversibly adsorbs and desorbs moisture in the air. Since negative ions due to the Leonard effect and the Simpson effect can be generated and supplied to the air conditioning area, a desiccant air conditioning system capable of supplying the negative ions while humidifying or heating the air conditioning area can be obtained.

Further, by providing sensible heat exchanger means for exchanging sensible heat between air dehumidified by the adsorption element and heated to a high temperature by the heat of adsorption, and regenerated air flowing through the heating means, the regenerated air is provided. In addition to the heat recovery of the heat of adsorption, the required input of the heating means can be reduced, and the processing air is cooled only by the sensible heat of the air that has become hot due to the heat of adsorption, and the specific enthalpy value decreases. The cooling capacity of the air conditioning area is improved, and a desiccant air conditioning system with an excellent coefficient of performance can be obtained.
