Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an indoor humidity control system utilizing solar heat.

[0002]

2. Description of the Related Art A dehumidifying device provided with a desiccant rotor as a humidity control unit, which uses solar energy for drying and regenerating the desiccant rotor to keep running costs low, has been conventionally known. (See, for example, JP 2000-210529 A).

Further, in a building provided with the desiccant dehumidifying device as described above, a moisture absorbing / releasing agent is provided on a partition wall of the room, etc. It is also known that even if the desiccant dehumidifying device is stopped, the moisture absorbing / releasing agent is used to keep the indoor dry state.

[0004]

However, the above dehumidifying device equipped with a desiccant rotor is made as a dehumidifying dedicated device, and therefore is used in the summer and not in the winter, and therefore the annual operating rate is reduced. However, even if the running cost can be kept low by solar energy, it takes a long time to depreciate the initial cost, and there is a problem that the cost merit is hard to come out.

Further, in the dehumidifying operation using the above dehumidifying device, when the air passes through the desiccant rotor and is dehumidified and dried, the temperature of the air rises due to the heat of adsorption, and the heated dry air blows out into the room. Therefore, there is a problem that the comfort of the room is impaired or the sensible heat load is increased to increase the energy consumption of other air conditioners, for example, in summer.

Further, in the case where the moisture absorbing / releasing agent is provided on the partition wall of the room, this moisture absorbing / releasing agent is certainly
Although it is dried by the air that has been dried by the dehumidifier, the moisture contained in the indoor air is also absorbed at the same time, so it is difficult for the drying to proceed sufficiently.Therefore, maintain the indoor dry state for a long time after the dehumidification operation is stopped. There was a problem that it was difficult.

In view of the above-mentioned conventional problems, the present invention makes it possible to keep running costs low by utilizing solar energy in a system provided with a humidity control section such as a desiccant rotor, and the annual operating rate. The goal is to raise the initial cost and realize early depreciation of the initial cost, thereby keeping the total cost low. In the dehumidifying operation in summer,
Another challenge is to be able to economically cool the dehumidified and dried heated outside air that is taken into the room.

[0008]

Means for Solving the Problems The above-mentioned problem is provided with a solar heat collecting portion for collecting solar heat with air, and an adsorbent for absorbing moisture from the first passing air and releasing moisture to the second passing air. An indoor humidity control system using solar heat provided with a humidity control section, wherein air from the solar heat collecting section is passed to the humidity control section as the second passing air and exhausted to the outside, and
Or, the indoor dehumidifying state in which the air in the room is passed through the humidity control section as the first passing air to the room and the air from the solar heat collecting section is passed through the humidity control section as the second passing air in the room And a switching means for switching the indoor and / or underfloor air or the outside air or the outside air through the humidity control section as the first passing air and exhausting it outside the room for indoor humidification. This is solved by the indoor humidity control system utilizing solar heat (first invention).

In this system, when the switching means is set to the indoor dehumidifying state in the summer, the outside air and / or the indoor air is absorbed by the humidity control section, dried and supplied to the inside of the room to dehumidify the inside of the room. It At this time, in the humidity control section, the air from the solar heat collecting section passes, the air is dehumidified, and the humidity control section is regenerated.

Further, in the winter season, when the switching means is set to the indoor humidifying state, the air from the solar heat collecting portion is supplied into the room and the room is heated by the solar heat. Then, the humidity control section absorbs moisture by the passage of high-humidity indoor and / or underfloor air or outdoor air exhausted to the outside, and at this time, the humidity control section includes dry air from the solar heat collecting section. To pass through, the air is dehumidified, and the air is supplied to the room to humidify the room.

As described above, in this system, by switching the state by the switching means, it is possible to dehumidify the room in the summer and to humidify the room in the winter, thereby increasing the annual operating rate of the system. It is possible to realize early depreciation of initial costs.

Of course, during the dehumidifying operation in summer, the humidity control section is regenerated by utilizing solar heat.
The running cost during the dehumidifying operation in summer can be kept low.

Further, during the humidifying operation in winter, the room is heated by solar heat, so that the heating cost can be kept low, and the humidification of the heating air into the room is exhausted outside the room with high humidity. Since it is performed using the above air and / or the air under the floor or the outside air, the running cost of the humidifying operation in winter can be suppressed to be low.

In particular, during the humidifying operation in winter, the heating air into the room is humidified by using both the indoor air having a high humidity exhausted outdoors and the air under the floor or the outside air. In this case, it is possible to secure a large amount of moisture absorption in the humidity control section, and it is possible to effectively humidify the above-mentioned air for indoor heating.

The outside air and / or the indoor air that has passed through the sensible heat exchange unit may be supplied into the room (second invention).

In the system according to the second aspect of the present invention, when the indoor dehumidifying state is set by the switching means in the summer, the temperature rises due to the heat of adsorption due to the moisture absorption in the humidity control section when passing through the humidity control section and dehumidifying and drying. In the sensible heat exchange section, the outside air and / or the indoor air exchanges heat with the air exhausted to the outside by cooling the room or the like and / or cool air under the floor to cool the temperature and supply the indoor air. The comfort is not impaired, and the sensible heat load is not increased and the energy consumption of other air conditioners is not increased.

Moreover, since the outside air and / or the indoor air that has passed through the humidity control section and has been dehumidified and has risen in temperature is exchanged with the air discharged to the outside to lower the temperature, the dehumidified outside air and It is possible to economically cool the inter-room air and supply it to the room.

Further, in the system of the first aspect of the present invention, the sensible heat exchange section is provided, and in the indoor humidification state, the air under the floor and / or the outside air passing through the humidity control section is exhausted to the outside. Before this is done, heat is exchanged with outside air and / or room air in the sensible heat exchange section, and this outside air and / or room air that has passed through the sensible heat exchange section is supplied to the room. Good (3rd invention).

In the system according to the third aspect of the present invention, when the indoor humidifying state is set by the switching means in winter, the outside air for ventilation supplied to the room is warm indoor air and / or underfloor air that has passed through the humidity control section. Alternatively, since the temperature is raised by exchanging heat with the outside air, it is possible to prevent the cold outside air from entering the room as it is and impair the comfort of the room in winter.
Moreover, since the outside air is heat-exchanged with the air exhausted to the outside to raise the temperature, the outside air for ventilation can be raised in temperature economically and supplied to the inside of the room.

In the system according to any one of the first to third aspects of the present invention, heat storage means is provided, and the air from the solar heat collecting portion passes through the heat storage means and then passes through the humidity control portion. It may be done (fourth invention).

In this case, the air from the solar heat collecting portion passes through the heat storage means to store the heat of the solar heat in the heat storage means. Therefore, when the switching means is used for indoor dehumidification, the heat is stored in the heat storage means during the daytime in summer, so the heat stored in the heat storage means is used for regeneration of the humidity control section at night when the sun does not shine. Even in the summer night, the outdoor air and / or the indoor air passes through the humidity control section to be dehumidified and dried, and the indoor can be dehumidified.

Moreover, unlike the case where the moisture absorbing / releasing agent is provided on the partition wall, the dry condition in the room during the summer night can be maintained for a long time.

In the system according to any one of the above first to third inventions, a heating means is provided, and the air from the solar heat collecting portion passes through the heating means and then passes through the humidity control portion. It may be done (fifth invention).

In the system according to the fifth aspect of the present invention, the unheated air from the solar heat collecting section is heated by the heating means during the daytime or the nighttime when the sun does not illuminate in winter or summer and during the rainy season when the sun does not illuminate. By heating and using the heated air, the humidity control section can be regenerated during the dehumidifying operation, and the humidified air can be sent into the room during the indoor humidifying operation.

In addition, in the system of the above-mentioned fourth invention, a heating means is provided, and the air from the solar heat collecting portion is
After passing through the heat storage means, it may pass through the heating means, and then pass through the humidity control section (sixth invention).

Also in the system of the sixth aspect of the present invention, it is possible to dehumidify or humidify the room in the daytime or the night when the sun does not illuminate in the winter or summer, or during the rainy season when the sun does not illuminate. Particularly, in this system, the heat storage means is also provided, so that the air from the solar heat collecting portion passes through the heat storage means, then passes through the heating means, and then passes through the humidity control portion. Therefore, when heat is stored in the heat storage means, the heat of this heat storage means can be used to continue dehumidification in the summer and humidification in the winter, and if it is still not possible to use the humidification means for the first time.

As the solar heat collecting unit 3, for example, a metal plate in which a large number of small holes are opened in a dispersed state is used as a heat collecting element, and air including the small holes is passed through the metal plate heated by solar energy. Therefore, the solar heat collector configured to collect air can be preferably used in that solar heat can be collected efficiently and effectively. It should be noted that the present invention is not limited to such a specific solar heat collector, and may be one that collects air by exchanging heat of water heated by solar heat energy with air.

The humidity control section 4 is composed of a desiccant rotor and is provided with an adsorbent such as zeolite or silica gel to absorb moisture from the first passing air and release it to the second passing air.

The first port 9 a of the second switching damper 9 is connected to the connection passage with the first port 8 a of the damper 8 via the sensible heat exchange section 5. In addition, the second port 8 of the first switching damper 8
An outlet 12 is connected to b through an air supply fan 6, and a second port 9b of a second switching damper 9 and a humidity control unit 4 are exposed to a third port 8c of the first switching damper 8. The first switching damper 8 is connected through the heat exchange unit 5 and
An exhaust port 11 is connected to the fourth port 8d of FIG. In addition, the third of the second switching damper 9
The air supply port 10 is connected to the port 9c and the second port
The suction port 13 is connected to the fourth port 9d of the switching damper 9.

It is formed by connecting b and the third port 9c.

This indoor dehumidifying state is used in the summer and rainy seasons, and the exhaust fan 7 is used during the day when the sun shines.
And the air supply fan 6 are driven, the heated air from the solar heat collecting section 3 passes through the humidity control section 4 as the second passing air (air that receives moisture released from the humidity control section 4). The humidity control section 4 is regenerated and is exhausted (EA) to the outside through the exhaust port 11, and the high-humidity outside air (OA) taken in from the air supply port 10 passes through the humidity control section 4 through the first passing air (conditioning). The air that has been absorbed by the damp section 4) passes through, is dehumidified and dried,
The room 2 is blown out (SA) through the air outlet 12 to dehumidify the room.

Heat exchange with the indoor air. That is, the humidity control section 4
The outside air that has passed through the chamber and has been dehumidified and dried rises in temperature due to the heat of adsorption as it passes through the humidity control unit 4. Therefore, when the room 2 is cooled, heat exchange with the cool air exhausted from the room 2 is performed. By performing the above, the temperature is lowered and then blown into the room 2, whereby the rise in room temperature due to the heat of adsorption as described above is suppressed. Of course, this heat exchange is performed using the exhausted indoor air, so that there is a great cost advantage.

Further, the air from the solar heat collecting section 3 is dry because it is in the winter, but passes through the humidity adjusting section 4 as the second passing air (air which receives the moisture released from the humidity adjusting section 4) and is humidified. Since the air is blown out into the room through the air outlet 12 (SA), the room 2 is heated and humidified.
At this time, the high-humidity room air (RA) sucked into and exhausted from the suction port 13 passes through the humidity control section 4 as the first passing air (air that is absorbed by the humidity control section 4), thereby controlling the humidity. Moisture is absorbed by the damp section 4. Since this moisture absorption is performed using the exhausted indoor air having high humidity, the humidification can be performed efficiently.

The outside air for ventilation which is taken in through the air supply port 10 and blows out into the room 2 is warm indoor air which is exhausted through the humidity control section 4 in the sensible heat exchange section 5 before being blown out into the room 2. Heat is exchanged with the temperature to raise the temperature, and then blown out into the room 2. Therefore, the temperature of the air in the room 2 warmed by the solar heat as described above is suppressed from being lowered by the outside air (OA) for ventilation. Since this heat exchange is performed using the exhausted indoor air, there is a great cost advantage. This outside air for heat exchange can be adjusted according to the required ventilation of the building, and when humidification is required or during the daytime, heat collection air is mainly taken in, and at night, heat exchange ventilation is mainly used.
