DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning space in which air contained in air to be supplied to an air-conditioning space is adsorbed by a desiccant and the air is dried. The present invention relates to a dehumidifying air-conditioning method and an apparatus for sending the air into the apparatus, and a method for using the apparatus. It can be suitably used for air-conditioning of a building having a volume of a space to be air-conditioned.

[0002]

2. Description of the Related Art Conventionally, when air-conditioning various types of buildings, particularly a building having a large volume of air-conditioned space such as a factory, water contained in air supplied to the air-conditioned space is desiccated by a desiccant. So-called dehumidifying air-conditioning (desiccant air-conditioning) is performed, in which the air is dried by being adsorbed on a (dehumidifying agent) and then cooled and sent into a space to be air-conditioned.

FIG. 7 shows an entire configuration of a dehumidifying air conditioner 80 which is an example of a conventional device for performing such dehumidifying air conditioning.

In FIG. 7, a dehumidifying air-conditioning apparatus 80 includes an air supply section 81 for supplying air-conditioned air into an air-conditioned space 93 on the right side of the drawing, and a desiccant by taking in return air from the air-conditioned space 93. And a regenerating unit 82 for performing the regenerating process and discharging the same to the outside. Then, in the air supply unit 81, an air flow (arrows X1 to X
4) is formed by the air supply fan 83, while the regeneration unit 8
In FIG. 2, an air flow (arrows Y1 to Y4) flowing from the right to the left in the drawing is formed by the regeneration fan 84 so as to oppose the flow.

The dehumidifying air conditioner 80 includes a dehumidifying rotor (desiccant rotor) 85 and a heat exchanging heat exchanging rotor (sensible heat rotor) disposed over the air supply unit 81 and the regenerating unit 82, respectively. ) 86 is provided.
The dehumidifying rotor 85 is formed by filling a desiccant that adsorbs moisture contained in air.

Further, the dehumidifying air conditioner 80 includes an air supply section 81.
A hot water coil 87 provided on the side, a hot water coil 88 provided on the regeneration section 82 side, a hot water boiler 89 and a boiler pump 90 for switching and supplying hot water to these, and a hot water coil 87 provided on the air supply section 81 side. A humidifier 91 and an evaporative cooler 92 provided on the regeneration section 82 side.

In such a dehumidifying air conditioner 80,
Air-conditioning of the space 93 to be air-conditioned is performed as follows.

First, when cooling is performed in summer, air is supplied to the air supply unit 81 by turning the air supply fan 83 from outside (arrow X1). The moisture contained is adsorbed on the desiccant and dried (arrow X2), and the dried air is cooled by passing through the heat exchange rotor 86 (arrow X).
3) The air-conditioned air is supplied into the air-conditioned space 93 (arrow X4).

On the other hand, in parallel with this, air is taken from the air-conditioned space 93 into the regenerating section 82 by turning the regenerating fan 84 (arrow Y1) and cooled by passing it through the evaporative cooler 92. The heat exchange rotor 86 is cooled by passing through the heat exchange rotor 86 (arrow Y2). At this time, heat exchange is performed with the air supply unit 81 via the heat exchange rotor 86. Then, the air that has passed through the heat exchange rotor 86 and has been heated by heat exchange is heated by the hot water coil 88 for regeneration (arrow Y3), and the moisture adsorbed on the desiccant of the dehumidification rotor 85 by the heated high-temperature air. After evaporation
The high-temperature and high-humidity air that has passed through the dehumidification rotor 85 is discharged to the outside (arrow Y4).

When heating is performed in winter, the dehumidification rotor 85 is not operated, and the air supply fan 83 is turned to take in air from the outside into the air supply unit 81 (arrow X1). After performing heat exchange with the air on the side of the regenerating unit 82, the air is heated by the hot water coil 87, and if necessary, humidified by the humidifier 91. (Arrow X
4).

According to the dehumidifying air conditioner 80, the humidity can be removed first, and then the air can be cooled as needed, so that the humidity and the temperature can be controlled separately. Therefore, in conventional air conditioners, air was supercooled to lower the humidity, and then the temperature was too low. At 80, since the dried air is cooled, it is possible to improve the energy efficiency and avoid excessive low-temperature cooling.

[0012]

However, although the dehumidifying air conditioner 80 described above is a device sufficient for improving energy efficiency and the like as compared with a conventional air conditioner, the dehumidifying rotor 85 is regenerated. Since about 90 degrees of heat is required for this, a hot water coil 88 and a hot water boiler 89 for supplying hot water thereto are used to secure a heat source for this.

[0013] Such a hot water boiler 89 and the like,
The larger the dehumidifying air conditioner 80, the larger the equipment must be. Therefore, a heat source is secured by other means or other means for assisting them, and it is not necessary to use them. If the size of the equipment can be reduced, the energy efficiency can be further improved and the energy saving effect can be improved, which is advantageous.

Further, if such other means can suppress the generation of carbon dioxide (CO ₂ ) which causes global warming, it becomes environmentally preferable and meets the demands of the times. It will be along.

By the way, apart from such a dehumidifying air conditioner 80, the following device utilizing solar heat has been devised as a device for heating in winter. That is, a heat collecting panel for absorbing solar heat is installed along the outer wall surface of the building, and the outside air warmed by heat exchange with the heat collecting panel is sent into the room to perform heating (Japanese Patent Laid-Open No. Hei-2-2). 2
No. 79954, Japanese Patent No. 2675385, etc.).

Since such a heating device utilizes solar heat, it can suppress the generation of CO ₂ and can be said to be an environmentally preferable device. However, if a single building is to be cooled in summer, a dehumidifying air conditioner must be used. 80, and even if such a heating device utilizing solar heat is simply provided, there is no relevance between the two devices. Therefore, during the summer cooling, the hot water boiler 89 of the same size as before is still used.
And the like, and simply installing a heating device using solar heat cannot be another means as described above.

An object of the present invention is to provide a dehumidifying air-conditioning method, an apparatus thereof, and a method of using the apparatus, which can further improve energy efficiency and are environmentally preferable.

[0018]

SUMMARY OF THE INVENTION The present invention aims at achieving the above object by skillfully combining a heating device using a heat collecting panel for solar heat absorption and a dehumidifying air conditioner using a desiccant for dehumidifying. Is what you do.

Specifically, the present invention relates to a method for adsorbing moisture contained in air supplied into a space to be air-conditioned to a desiccant and drying the air, and then cooling the dried air to cool the air-conditioned object. In the dehumidifying air-conditioning method for sending air into a space, a heat collecting panel that absorbs solar heat is provided outside the outer peripheral surface of the building along the outer peripheral surface, and the outside air heated by exchanging heat with the heat collecting panel is provided. Thus, the desiccant adsorbing moisture is dried and regenerated.

Here, the outer peripheral surface of the building includes not only the outer wall surface but also the roof surface. In addition, the buildings include various structures such as hulls of ships, in addition to factory buildings, warehouses, office buildings, general houses, and the like. Further, the air-conditioned space includes rooms, passageways, halls, factories, warehouses, and the like in ordinary buildings, the premises of subway stations, underground shopping malls, tunnels, and ships.

In the present invention, since the desiccant in a state of adsorbing moisture is dried and regenerated by the external air warmed by heat exchange with the heat collecting panel, the prior art shown in FIG. Hot water boiler 8 like dehumidifying air conditioner 80
Instead of using only 9 as the heat source to regenerate the desiccant, it is possible to secure a heat source for regenerating the desiccant only by using the warm air from the heat collecting panel and the hot water boiler or using only the warm air from the heat collecting panel.

For this reason, in addition to the effects obtained by the conventional dehumidifying air conditioner 80, such effects as improvement of energy efficiency by cooling the dried air and avoiding excessive low-temperature cooling can be obtained. Since the solar heat is used, the energy efficiency is further improved, and the energy saving effect is further improved.

Further, since solar heat is used, CO ₂
Because it can suppress the generation of the gas, it is useful for prevention of global warming, is an environmentally preferable device, and meets the demands of the times.

Since each of these effects can be obtained during cooling, it is clearly different from the case where the conventional dehumidifying air conditioner 80 and the heating device using solar heat are provided together as described above. is there. In other words, in a mere installation that does not have any relationship between the two devices, it is possible to obtain an energy saving effect and a CO ₂ suppression effect by utilizing solar heat only during heating, whereas in the present invention, these devices are not used during cooling. Since the effects can be obtained, it is obvious that the invention is not a simple invention in which the two devices are simply assembled but an inventive invention in which the two devices are skillfully combined.

Further, as an apparatus for realizing the above-described dehumidifying air-conditioning method of the present invention, there is the following dehumidifying air-conditioning apparatus of the present invention.

That is, the present invention provides a dehumidifying means formed by loading a desiccant which adsorbs moisture contained in air supplied into an air-conditioned space, and air dried by the dehumidifying means by heat exchange. In a dehumidifying air conditioner provided with a heat exchange means for cooling, heat exchange is performed between a heat collecting panel for solar heat absorption provided outside the outer peripheral surface of the building along the outer peripheral surface and the heat collecting panel. And regenerating warm air supply means for sending the warmed outside air to the dehumidifying means to dry and regenerate the desiccant in a state of adsorbing moisture.

Here, it is preferable that the dehumidifying means is filled with a desiccant without substantially any gap, but the present invention is not limited to this, and the dehumidifying means may be charged at a certain interval. In addition, the structure of the dehumidifying means may take the form of a disk-shaped dehumidifying rotor that is disposed across the air supply unit side (the side that performs the dehumidification process) and the regeneration unit side (the side that regenerates the desiccant). It is preferable in that the structure is such that the loaded desiccant can be easily reciprocated between these parts. However, the present invention is not limited to this. In other words, the dehumidification process and the regeneration process can be performed alternately. What is necessary is just a structure which can be performed.

In the present invention as described above, the warm air obtained by heat exchange with the heat collecting panel is sent to the dehumidifying means by the regenerating warm air supplying means, and is used once for performing the dehumidifying treatment to absorb moisture. Since the desiccant in the state is dried and regenerated, the operational effects obtained by the above-described dehumidifying air-conditioning method of the present invention are realized as they are.

Further, the present invention provides the above dehumidifying air conditioner, wherein an air supply unit for processing air taken in from the outside and supplying the air into the space to be air-conditioned, and processing the air taken from the space to be air-conditioned and discharging it to the outside. Exhaust unit, and a regenerating unit for drying and regenerating the desiccant of the dehumidifying means, the air supply unit,

A discharge processing unit that discharges air after being used to cool the replacement unit to the outside, and the regeneration unit includes a regeneration warm air that introduces warmed outside air sent by the regeneration warm air supply unit. It is preferable to adopt a configuration including an introduction section and a desiccant regeneration processing section for drying and regenerating the desiccant of the dehumidifying means by the warm air introduced into the regeneration warm air introduction section.

In the case where the three air flows of the air supply unit, the exhaust unit, and the regeneration unit are formed in the dehumidifying air conditioner, the desiccant is supplied by supplying warm air from the heat collecting panel. In the regeneration, the flow (arrows X1 to X1) of the air supply unit 81 in the conventional dehumidifying air conditioner 80 of FIG.
X4) and the flow of the regeneration unit 82 (arrows Y1 to Y4) can further improve the energy efficiency as compared with the case where the warm air is supplied with the two air flows.

That is, when the warm air from the heat collecting panel is to be supplied with the two air flows of the conventional dehumidifying air conditioner 80, the air (arrow Y3) after passing through the heat exchange rotor 86 is supplied. Since the temperature is different from the temperature of the warm air from the heat collecting panel, the heat of the warm air from the heat collecting panel cannot be directly supplied to the desiccant of the dehumidifying rotor 85, and the energy efficiency is reduced. On the other hand, in the present invention, the conventional regeneration unit 82 is divided into two parts, an exhaust unit and a regeneration unit, and the exhaust processing unit of the exhaust unit uses the air after being used to cool the heat exchange means. Is discharged to the outside, so that the warm air from the heat collecting panel does not mix with the air used to cool the heat exchange means, so that the energy efficiency can be improved. Become.

As a method of using the dehumidifying air-conditioning apparatus of the present invention described above, the following method can be mentioned.
That is, the method of using the dehumidifying air-conditioning apparatus of the present invention is such that, when heating is performed, the dehumidifying unit is deactivated, and the external air heated by exchanging heat with the heat collecting panel is dried by the drying agent of the dehumidifying unit. Instead of being used for reproduction of the air-conditioner, it is supplied into the air-conditioned space.

If heating is performed in this manner, it is possible to use warm air from the heat collecting panel not only during cooling but also during heating, so that energy efficient operation is performed in any of the spring, summer, autumn and winter seasons. Will be able to do it. In addition, since heating using solar heat is performed, not only during cooling but also during heating, it is possible to consider the environment and improve energy saving effects by suppressing the generation of CO ₂ as described above. .

In the present invention described above, the heat collecting panel has a large number of through holes for taking in outside air into the air collecting space formed between the heat collecting panel and the outer peripheral surface. Or the above-mentioned JP-A-2-22-2.
No. 79954, Japanese Patent No. 2675385, etc., the flow of outside air is formed along the inner surface (the building-side surface) or the outer surface (the sun-side surface) of the heat collecting panel,
At this time, heat exchange between the outside air and the heat collecting panel may be merely performed.

Further, in the present invention, a heat collecting panel for absorbing solar heat is used as a means for obtaining warm air for regenerating the desiccant, but other than the heat collecting panel, for example, a specially provided heat collecting panel may be provided. The same effect as that of the present invention can be obtained by using warm air obtained by performing air heating using a greenhouse or a box or by using a solar cell power supply to regenerate a drying agent. By using the warm air forming means for warming the air by utilizing the above, the same effects as those of the present invention can be obtained, such as further improvement of energy efficiency and environmental consideration accompanying suppression of generation of CO ₂ .

Heat is exchanged between the outside air and the heat collecting panel 20 by sucking the air into the insides 1 and 22 to obtain warm air for regenerating the desiccant. Then, the warm air in the air collecting spaces 21 and 22 is introduced into the regeneration warm air introduction unit 43A of the regeneration unit 43 through the chamber 23, the duct 24, and the regeneration warm air introduction port 61.

Subsequently, if necessary, hot water is supplied from the hot water boiler 51 to the hot water coil 50 for regeneration.
By 0, the warm air introduced into the regeneration warm air introducing section 43A is further heated (arrow N1). If necessary, for example,
If only the heat of warm air obtained by heat exchange with the heat collecting panel 20 on a sunny day or the like is sufficient, the hot water boiler 51 and the hot water coil 50 may be in an inactive state or a low-temperature operating state, and conversely, Heat collecting panel 2 on rainy days
When the heat of warm air obtained by heat exchange with 0 is not sufficient, it means that these are brought into an operating state.

Then, in the desiccant regeneration processing section 43B, the moisture adsorbed on the desiccant of the dehumidification rotor 47 is evaporated by the warm air introduced into the regeneration warm air introduction section 43A or the high temperature air further heated by the hot water coil 50. Let it be removed. Thus, the desiccant filled in the dehumidifying rotor 47 is
It is regenerated and used again for the dehumidification processing in the adsorption processing section 41A of the air supply section 41.

Thereafter, the high-temperature, high-humidity air that has passed through the dehumidification rotor 47 is discharged to the outside from the regeneration warm air discharge port 57 (arrows N2, N3, N4). The above is the flow of processing when cooling is performed.

On the other hand, when performing heating, the air supply fan 44 and the regeneration fan 46 are operated, and the dampers 56 and 58 are closed and the damper 60 is opened. FIG. 5 shows the flow of air during heating in the system conceptual diagram of the dehumidifying air conditioner 10.

That is, in FIG. 5, first, by turning on the air supply fan 44 and the regeneration fan 46, the warm air in the air collecting spaces 21 and 22 obtained by heat exchange with the heat collecting panel 20 is
The gas is introduced into the regeneration warm air introduction section 43A of the regeneration section 43 through the chamber 23, the duct 24, and the regeneration warm air introduction port 61.

Next, the introduced air is sent to the air supply section 41 through the communication passage 59 (arrows T1, T2, T3). At this time, the dehumidifying rotor 47 is not operated because it does not perform the dehumidifying process as in cooling. Therefore, unlike during cooling, the warm air obtained by heat exchange with the heat collecting panel 20 is not used for regenerating the desiccant filled in the dehumidifying rotor 47.

Subsequently, the warm air sent to the air supply section 41 is sent to the position of the heat exchange rotor 48 (arrows T4, T5, T
6). Here, if necessary, the exhaust fan 45 is turned to introduce warm air in the room from the inside of the air-conditioned space 4 through the exhaust duct 31 to the exhaust portion 42 and form a flow for discharging the warm air from the exhaust port 62 to the outside. (Arrows S1, S2, S
3). Thereby, ventilation of the air-conditioned space 4 can be performed. At this time, the evaporative cooler 54 is not operated.

When the heat exchange rotor 48 is operated in such a state that the flow of the exhaust part 42 is formed, heat exchange between the exhaust part 42 and the air supply part 41 is performed via the heat exchange rotor 48. Then, the heat of the warm air discharged from the air-conditioned space 4 can be recovered. However, the heat exchange rotor 48
Does not need to be activated when there is no need for heat exchange.

In the process up to this point, the warm air is further heated by one of the hot water coil 49 and the hot water coil 50 as necessary. If there is a special situation as described above, heating may be performed by both the hot water coils 49 and 50. Note that heating by the hot water coils 49 and 50 is not necessarily performed, and the hot water boiler 51 need not be operated when unnecessary.

Here, when the heating is performed by the hot water coil 49, the air after the heat is recovered by the heat exchange rotor 48 is heated, so that the energy consumption of the hot water boiler 51 can be suppressed low. . That is, when supplying a certain amount of heat energy to the air-conditioned space 4, air having a lower temperature is supplied to the heat exchange rotor as compared with a case where the heat is recovered by the heat exchange rotor 48 after heating by the other hot water coil 50. 48, the heat exchange rotor 4
8, the efficiency of heat recovery by the hot water coil 49 can be reduced. When there is a special situation such as a failure of the damper 60 in the communication passage 59, the damper 56 is opened, outside air is introduced from the outside air inlet 55 for air supply as in the related art, and the hot air is heated by the hot water coil 49. The air for heating may be sent to the space 4 to be air-conditioned.

On the other hand, when heating is performed by the hot water coil 50, the hot water coil 50 is used not only for cooling but also for heating, so that the hot water coil 50 is also used for drying agent regeneration and heating. Can be. For this reason, it is possible to omit the installation of the hot water coil 49, and it is possible to simplify the device configuration and reduce the manufacturing cost.

Thereafter, the humidifier 53 is humidified as required, and the air thus heated or humidified is supplied from the air outlet 32 into the air-conditioned space 4 through the air supply duct 30. Supply. The above is the flow of processing when heating is performed.

According to this embodiment, the following effects can be obtained. That is, since the dehumidifying air-conditioning apparatus 10 includes the heat collecting panel 20 and the regeneration warm air supply means 26 including the duct 24 and the like, the warm air obtained by heat exchange with the heat collecting panel 20 causes the dehumidifying rotor 47 to rotate. The desiccant can be dried and regenerated.

Therefore, instead of using only the hot water boiler 89 as a heat source to regenerate the desiccant as in the conventional dehumidifying air conditioner 80 shown in FIG. 7, the warm air from the heat collecting panel 20 and the hot water boiler 51 are used together, or The heat source for regenerating the desiccant can be secured only by the warm air from the heat collecting panel 20.

For this reason, the effects obtained in the conventional dehumidifying air conditioner 80 include the improvement of the energy efficiency by cooling the dried air, the avoidance of excessive low-temperature cooling, the avoidance of the use of CFCs and alternative CFCs, and the like. In addition to the effect of suppressing the growth of mold and bacteria, the use of solar heat can further improve the energy efficiency, and can further enhance the energy saving effect.

Also, since solar heat is used, CO ₂
Since it is possible to suppress the generation of the gas, it is possible to prevent global warming, to be environmentally preferable, and to realize a device that meets the demands of the times.

The air conditioning process is performed by taking in a large amount of outside air from the outside air intake port 55 for air supply to the air supply section 41 instead of circulating room air as in a conventional air conditioner. A comfortable indoor air environment can be maintained. For this reason, the dehumidifying air conditioner 10 is not limited to a factory,
It can be suitably used as an air conditioner for supermarkets, hospitals, nursing homes, schools, hotels and the like. The dehumidifying air conditioner 10 may be used for drying tea, cigarettes, and grains.

Further, since a large number of through holes 25 are formed in the heat collecting panel 20 (see FIG. 4), heat can be exchanged when outside air passes through these through holes 25. The heat can be absorbed very efficiently.

Further, the heat loss in the air-conditioned space 4 from the outer wall surface 2 and the roof surface 3 can be recovered in the air-gathering spaces 21 and 22, so that the energy efficiency can be further improved. .

Since the air collecting spaces 21 and 22, which are air layers, are formed between the heat collecting panel 20 and the outer wall surface 2 or the roof surface 3, in summer, radiant heat is cut off to insulate. The effect can be enhanced.

In the main body 11 of the dehumidifying air conditioner 10, three air flows of an air supply section 41, an exhaust section 42, and a regeneration section 43 are formed. When the desiccant is regenerated by supplying warm air, the flow (arrows X1 to X4) of the air supply unit 81 and the regenerating unit 8 in the conventional dehumidifying air conditioner 80 of FIG.
Energy efficiency can be further improved as compared with a case where warm air is supplied with two flows of air (arrows Y1 to Y4).

That is, in the dehumidifying air-conditioning apparatus 10, the portion corresponding to the regeneration section 82 of the conventional dehumidifying air-conditioning apparatus 80 is divided into an exhaust section 42 and a regeneration section 43, and the exhaust section 4
The air used after cooling the heat exchange rotor 48 is discharged to the outside from the exhaust port 62 by the exhaust fan 45 provided in the second exhaust processing section 42C. Mixing with warm air from 21 and 22 can be avoided. Therefore, the air collection space 2
The heat of warm air from 1 and 22 can be directly supplied to the desiccant filled in the dehumidifying rotor 47, and the energy efficiency can be improved.

Further, at the time of heating, the dehumidifying rotor 47 is deactivated, and the warm air obtained by heat exchange with the heat collecting panel 20 is not used for regenerating the desiccant filled in the dehumidifying rotor 47, but for air conditioning. Since it is supplied into the target space 4 (FIG. 5
), Not only during cooling but also during heating, the warm air obtained by heat exchange with the heat collecting panel 20 can be used, and energy efficient operation can be performed in any of the spring, summer, autumn and winter seasons. . And since it is heating using solar heat, not only at the time of cooling but also at the time of heating, it is possible to consider the environment and improve the energy saving effect by suppressing the generation of CO ₂ as described above.

Since the communication path 59 and the damper 60 are provided, the warm air introduced into the regeneration warm air introduction section 43A of the regeneration section 43 through the regeneration warm air introduction port 61 is removed.
The air can be sent to the air supply unit 41 to be used as heating air (see FIG. 5). Therefore, since the hot water coil 50 is placed in the middle of the heating air supply path, the hot water coil 50 can be used not only at the time of cooling but also at the time of heating, and the hot water coil 50 is used for regenerating the desiccant. And can be used for heating. For this reason, the installation of the other hot water coil 49 can be omitted, and the device configuration can be simplified and the manufacturing cost can be reduced.

Further, since the air outlets 32 are provided at appropriate intervals above the air supply duct 30 (see FIG. 2), the air conditioned from these air outlets 32 is supplied at a constant speed. The air can be blown into the air-conditioned space 4. Therefore, the convection of the air is efficiently performed, and the temperature in the air-conditioned space 4 can be made uniform. And
By making the temperature in the air-conditioned space 4 uniform, extra heating or cooling can be minimized, and a high energy saving effect can be obtained.

The present invention is not limited to the above-described embodiment, but includes modifications and the like within a range that can achieve the object of the present invention.

That is, in the above embodiment, the heat collecting panel 20 is installed on a part of the outer wall surface 2 and the roof surface 3, but either the outer wall surface 2 or the roof surface 3 may be used.
Moreover, it may be provided not only on a part of the roof surface 3 but on the entire surface. In short, it may be provided on the outer peripheral surface of the building 1, preferably on the south-facing surface.

A solar cell is mounted on the outer surface of the heat collecting panel 20 and the dehumidifying rotor 47 and the heat exchanging rotor
It may be used as an energy source for each part of the dehumidifying air-conditioning apparatus 10, such as a rotary drive of 8, or a heat source of the hot water boiler 51, or an auxiliary thereof.

Furthermore, in the above-described embodiment, when heating is performed, warm air from the air collecting spaces 21 and 22 is first passed through the main body 11 and then is passed through the air supply duct 30 into the air-conditioned space 4. (See FIG. 5), for example, as shown in FIG. 6, a path for directly supplying the air-conditioned space 4 without passing through the main body 11 may be provided.

In FIG. 6, a damper 71 is provided in the middle of the air supply duct 70 so that the path can be switched and the flow rate of each switched side can be adjusted. By performing the switching operation of the damper 71, the air collecting spaces 21 and
On the one hand, the warm air in 2 goes from the chamber 23 to the outlet 73 of the air supply duct 70 directly through the damper 71 by turning the air supply auxiliary fan 72 (arrow P), and from the chamber 23 on the other hand. After being passed through the main body 11 once through the duct 24, the air supply duct 7 passes through the damper 71.
0 is directed toward the outlet 73 (arrow Q).
The flow of the latter arrow Q is exactly the same as the flow at the time of heating in the above-described embodiment, but the flow of the former arrow P is different. When it is not necessary to perform humidification, it is not necessary to pass through the humidifier 53 provided in the main body 11, so only the flow of the former arrow P may be used. The flow of the former arrow P and the flow of the latter arrow Q may be used together instead of only the flow of the arrow Q. When the former flow of the arrow P is formed by turning the air supply auxiliary fan 72, the warm air near the ceiling of the air-conditioned space 4 can be partially taken in and reused (arrow R).

In the above embodiment, the air-conditioned space 4
Although the inside air is exhausted from the exhaust part 42 (see FIG. 3), the air in the air-conditioned space 4 is naturally exhausted, and outside air is introduced into the exhaust part 42 and this external air is used. Thus, the cooling and regeneration of the heat exchange rotor 48 may be performed.
