Subsequently, an embodiment embodying the present invention will be described with reference to the attached drawings, and the present invention will be understood.
As shown in FIG. 1, the air-conditioning equipment 10 according to the first embodiment of the present invention is an equipment for air-conditioning the interior space P of the building Q having the roof portion R, and is inside the building Q from the roof portion R. Moisture absorbing / releasing member 11 that is arranged at intervals and provides a ventilation portion T that allows air in the indoor space P to flow in between the roof portion R and the air in the indoor space P to the outside via the ventilation portion T. It is provided with an air transport device 12 capable of discharging. Hereinafter, it will be described in detail.

As shown in FIG. 1, the building Q provided with the air conditioner 10 has a roof portion R, a ceiling plate U that divides the inside of the building Q into an attic space S and an interior space P, and a wall surrounding the interior space P from the front, back, left and right. It has a part W. In the present embodiment, the roof portion R includes a rectangular inclined plate R1 and a rectangular inclined plate R2 smaller than the inclined plate R1, and an air pool portion H is formed at the highest position of the attic space S. .. An opening M is formed in the ceiling plate U, and the air in the attic space S and the air in the indoor space P can be exchanged through the opening M.

The moisture absorbing / releasing member 11 includes a moisture absorbing / releasing layer 13 which is made of cellulose fiber as a main raw material and spreads out in a plane, and a plate-shaped base material 14 to which the moisture absorbing / releasing layer 13 is attached from below. It is arranged below the inclined plate R1 at a distance from the inclined plate R1. The moisture absorbing / releasing layer 13 and the base material 14 are arranged in an inclined manner, are parallel to the inclined plate R1, and spread in a plane between the base material 14 (moisture absorbing / releasing member 11) and the inclined plate R1. A ventilation portion T is provided. One side of the ventilation portion T communicates with the air reservoir portion H, and the other side communicates with the indoor space P.

The moisture absorbing / releasing layer 13 has a moisture absorbing / releasing property capable of absorbing moisture from the surroundings and releasing the absorbed moisture to the surroundings. The base material 14 has moisture permeability and is arranged between the ventilation portion T and the moisture absorbing / releasing layer 13. Therefore, the moisture absorbing / releasing layer 13 can absorb moisture from the air in the attic space S, and the absorbed moisture can be discharged to the ventilation portion T through the base material 14 (that is, the moisture absorbing / releasing member 11 is in the attic space. Moisture can be absorbed from the air in S, and the absorbed moisture can be released to the ventilation unit T).

In addition to the moisture absorbing / releasing member 11, the air conditioning equipment 10 is arranged in the air pool portion H, has a thermometer 15 (ventilation portion thermometer) for measuring the temperature inside the ventilation portion T, and a fan provided on the ceiling plate U. It is provided with an air transport device 12 arranged in the attic space S having 16, a fans 17 and 18 provided in the wall portion W, and a temperature control device 19 for cooling and heating the indoor space P. The fan 17 is an example of ventilation means.
The fan 16 is normally operated, and by the operation, the air in the attic space S is sent to the indoor space P. When the fan 16 operates, the air in the indoor space P flows into the attic space S through the opening M, so that the air in the attic space S and the air in the indoor space P are constantly exchanged.

The fans 17 and 18 operate to exhaust the air in the interior space P to the outside. In this embodiment, fans 17 and 18 are provided in the living room and the bathroom, respectively. An opening M is formed in the ceiling plate U, air in the indoor space P can flow into the attic space S through the opening M, and air in the attic space S can flow into the indoor space P through the opening M. ..
As shown in FIGS. 1 and 2, in the air transport device 12, in addition to the fan 16, a ventilation pipe 20 having both ends arranged in the air reservoir H and outdoors, and a fan 21 and a damper provided in the ventilation pipe 20 are provided. 22 is provided with a ventilation pipe 23 having one end connected to the ventilation pipe 20, a damper 24 provided on the ventilation pipe 23, and a control unit 25 for controlling the fans 16, 21 and the dampers 22, 24.

The fan 21 is arranged closer to the air reservoir H than the damper 22, and by operation, the air in the air reservoir H is taken into the ventilation pipe 20 and sent out of the air reservoir H. As the air in the air reservoir H is sent out to the ventilation pipe 20, the air in the ventilation portion T flows into the air reservoir H, and the air in the interior space P flows into the ventilation portion T.
One end of the ventilation pipe 23 is connected to the ventilation pipe 20 between the fan 21 and the damper 22, and the other end is arranged in the attic space S.

The damper 22 is closed so that air does not pass through the installation position of the damper 22 of the ventilation pipe 20, and the damper 22 is opened so that air can pass through the installation position of the damper 22 of the ventilation pipe 20. The damper 24 is closed to prevent air from passing through the installation position of the damper 24 of the ventilation pipe 23, and is open to allow air to pass through the installation position of the damper 24 of the ventilation pipe 23. The open / closed state of the dampers 22 and 24 is changed by transmitting a signal from the control unit 25.

By operating the fan 21 with the dampers 22 and 24 in the open state and the closed state, respectively, the air in the air reservoir H is discharged to the outside through the ventilation pipe 20 as shown in FIG. Then, when the fans 21 are operated with the dampers 22 and 24 in the closed state and the open state, respectively, the air in the air pool portion H passes through the ventilation pipes 20 and 23 and the attic space S, as shown in FIG. Will be sent within.

As shown in FIG. 2, the control unit 25 is connected to the thermometer 15 in addition to the fan 21, the dampers 22 and 24, and can acquire the measured temperature of the thermometer 15. In the present embodiment, the control unit 25 is mainly composed of a CPU, a memory, and software installed in the memory, but is not limited thereto.
Further, the temperature control device 19 takes in the air in the attic space S (an example of the space in which the suction portion 19a is arranged) from the suction portion 19a, cools or heats the air, and then blows the air into the indoor space P. In FIG. 1, the description of the outdoor unit of the temperature control device 19 is omitted.

The control unit 25 intermittently acquires the measured temperature of the thermometer 15, and determines whether or not the water potential in the ventilation unit T is lower than the water potential of the indoor space P based on the acquired measured temperature of the thermometer 15. do. In the present embodiment, when the measured temperature of the thermometer 15 is the temperature t1 or higher, the control unit 25 determines that the water potential in the ventilation unit T is lower than the water potential in the indoor space P. A temperature t1 can be set in the control unit 25, and as the temperature t1, the temperature inside the ventilation unit T (for example, 30 to 50 ° C.) is considered to be lower than the water potential in the indoor space P in the summer. Predetermined temperature in the range of) is set.

Since the air in the attic space S and the air in the indoor space P are usually exchanged by the operation of the fan 16, the attic space S and the indoor space P are exchanged with each other in temperature, relative humidity, absolute humidity and moisture potential. Is approximated. When the temperature rises in the closed space, the moisture potential decreases. Therefore, when the inclined plate R1 absorbs the solar heat during the day and the temperature of the ventilation portion T rises, the moisture potential in the ventilation portion T decreases, and the ventilation portion T decreases. The moisture potential inside is lower than the moisture potential of the indoor space P and the roof space S.

Therefore, the moisture absorbed by the moisture absorbing / releasing layer 13 moves to the ventilation portion T through the base material 14, and the moisture (moisture in the air) of the attic space S is absorbed by the moisture absorbing / releasing layer 13 to form an indoor space. The phenomenon that the moisture of P moves to the attic space S occurs. Therefore, the humidity in the indoor space P moves to the attic space S, and moves from the attic space S to the ventilation portion T via the moisture absorbing / releasing member 11.

When the control unit 25 determines in the summer that the water potential in the ventilation unit T is lower than the water potential in the indoor space P and the attic space S based on the measured temperature of the thermometer 15, the dampers 22 and 24 are opened, respectively. And closed, and the fan 21 is operated, whereby the air in the indoor space P is discharged to the outside via the ventilation portion T, the air reservoir portion H, and the ventilation pipe 20 as shown in FIG. .. At this time, since the moisture potential of the ventilation portion T is lower than the moisture potential of the attic space S, the moisture in the attic space S moves to the ventilation portion T through the moisture absorbing / releasing member 11, and is collected together with the air in the ventilation portion T. It is discharged to the outside via the portion H and the ventilation pipe 20. As a result, the humidity of the indoor space P is discharged to the outside, and the indoor space P is dehumidified.

As shown in FIG. 2, the control unit 25 is connected to the control means 26 connected to the fan 17. The control means 26 can be configured mainly by a CPU, a memory, and software, can control the operation of the fan 17, and can acquire information on the operation status of the fan 21 and the dampers 22 and 24 from the control unit 25. The fan 17 installed in the living room usually rotates at a predetermined rotation speed to ventilate the interior space P. The fan 18 installed in the bathroom can be switched between rotation and stop by a manual operation.

From the information acquired from the control unit 25, the control means 26 operates the fan 21 with the dampers 22 and 24 in the open state and the closed state, respectively (that is, the air in the indoor space P is the ventilation unit T and the air). When it is detected that the air is discharged to the outside via the pool portion H and the ventilation pipe 20, the fan 17 is stopped or the rotation speed of the fan 17 is reduced to reduce the air discharge amount.

By this control, the control means 26 is outdoors from the inside of the building Q within a unit time before and after the air in the indoor space P is discharged to the outside via the ventilation portion T, the air reservoir portion H, and the ventilation pipe 20. Adjust so that the amount of air discharged to is the same. Then, when the control means 26 detects that the dampers 22 and 24 are in the open state and the dampers 22 are in the open state and the damper 21 is released from the operating state, the rotation of the fan 17 is restarted or the rotation of the fan 17 is started. Return the speed to the normal value.

Further, in the summer, when the measured temperature of the thermometer 15 is equal to or lower than the temperature t2 (for example, a predetermined temperature in the range of 20 to 25 ° C.), the temperature inside the ventilation unit T is higher than the temperature of the roof space S. It is determined that the temperature is low (that is, the temperature inside the ventilation unit T is lower than the temperature of the space where the temperature control device 19 takes in air), the dampers 22 and 24 are closed and opened, respectively, and the fan 21 is set. It is operated so that the air in the ventilation portion T is sent to the roof space S (the space in which the suction portion 19a of the temperature control device 19 is arranged) as shown in FIG. Since the air in the ventilation portion T is sent to the attic space S, the air is taken into the ventilation portion T from the indoor space P, and the air in the attic space S is sent to the indoor space P by the fan 16, so that air is conveyed. The device 12 returns the air in the indoor space P to the indoor space P via the ventilation unit T.

This is because the air in the ventilation portion T is sent to the indoor space P to lower the room temperature in the indoor space P at night in the summer, and the temperature in the ventilation portion T is lowered by the radiant cooling of the inclined plate R1. Is sent to the attic space S to lower the temperature of the attic space S, and the cooling load of the temperature control device 19 is reduced.
In the control unit 25, as the temperature t2, the temperature inside the ventilation unit T is considered to be lower than the temperature of the attic space S (the space where the temperature control device 19 takes in air) (for example, 20 to 25 ° C.). Range temperature) is set.

Then, in winter, when the temperature inside the ventilation unit T is equal to or higher than the temperature t3 (an example of a predetermined temperature) based on the measured temperature of the thermometer 15, the control unit 25 closes and opens the dampers 22 and 24, respectively. Then, the fan 21 is operated so that the air in the ventilation portion T is sent to the roof space S (the space in which the suction portion 19a of the temperature control device 19 is arranged). Therefore, the air transport device 12 returns the air in the indoor space P to the indoor space P via the ventilation unit T. This is because when the inclined plate R1 is heated by the sun heat and the temperature of the ventilation portion T rises during the daytime in winter, the air in the ventilation portion T is sent to the interior space P to raise the room temperature of the interior space P. This is because the air in the ventilation portion T whose temperature has risen is sent to the roof space S to raise the temperature of the roof space S and reduce the heating load of the temperature control device 19.

The temperature t3 is set in the control unit 25 at a temperature at which the temperature inside the ventilation unit T is considered to be higher than the temperature of the attic space S (for example, a temperature in the range of 15 to 25 ° C.) in winter. There are various methods for causing the control unit 25 to detect that the current season is summer or winter. For example, the control unit 25 may be made to acquire seasonal information via the Internet. The control unit 25 may be provided with a calendar function, or the control unit 25 may be connected to a changeover switch for detecting whether it is summer or winter.

Next, with reference to FIG. 5, the air conditioning equipment 30 according to the second embodiment of the present invention will be described. In the air conditioning equipment 30, the same components as those of the air conditioning equipment 10 are designated by the same reference numerals, and detailed description thereof will be omitted.
As shown in FIG. 5, the air conditioning equipment 30 heats or cools the moisture absorbing / releasing member 11, the air transport device 31 that sends out the air in the air reservoir H, and the air in the attic space S, and sends the air to the indoor space P. The device 32 is provided.

The air transport device 31 includes a fan 16, a fan 34 that discharges the air from the air reservoir H to the outside, and a fan 36 that transfers the air from the air reservoir H to the temperature control device 32 via a ventilation pipe (duct) 35. I have. One end of the ventilation pipe 35 is connected to the air suction portion 32a of the temperature control device 32. In the summer, when the measured temperature of the thermometer 15 is equal to or lower than the predetermined temperature, the fan 36 operates to directly transfer the air in the ventilation unit T to the air suction unit 32a of the temperature control device 32 via the ventilation pipe 35. In winter, when the measured temperature of the thermometer 15 is equal to or higher than a predetermined temperature, the fan 36 operates and the air in the ventilation section T is directly transferred to the air suction section 32a of the temperature control device 32 via the ventilation pipe 35. do. Thereby, the load of the cooling operation or the load of the heating operation of the temperature control device 32 can be reduced.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all changes in conditions that do not deviate from the gist are within the scope of the present invention.
For example, air conditioning equipment can be installed in a building that does not have an attic space. When installing air conditioning equipment in a building that does not have an attic space, a moisture absorption / desorption member is placed near the roof in the interior space to form a ventilation part between the moisture absorption / desorption member and the roof, and the moisture absorption / desorption member is provided. By allowing the roof to absorb moisture directly from the indoor space, the humidity in the indoor space can be discharged to the outside via the moisture absorbing / releasing member and the ventilation part.

In addition, when an air conditioner equipped with a temperature control device is installed in a building where there is no roof space, the space where the temperature control device takes in air is the indoor space (or the underfloor space), and the air transfer device is installed in the ventilation section in the summer. When it is determined that the temperature is lower than the temperature of the indoor space (or underfloor space) where the air is taken in, the air in the ventilation section is sent to the indoor space (or underfloor space), and the temperature inside the ventilation section is adjusted in winter. When the device determines that the temperature is higher than the temperature of the indoor space (or underfloor space) that takes in air, the air in the ventilation section is sent to the indoor space (or underfloor space).
Further, the ventilation portion does not need to communicate directly with the indoor space, and may communicate with the indoor space through a pipe or a space through which air flows.

Further, the control unit (that is, the air transport device) does not have to determine whether or not the water potential in the ventilation unit is lower than the water potential in the indoor space based only on the measured temperature of the ventilation unit thermometer. For example, by providing an indoor thermometer that measures the temperature of the indoor space in addition to the ventilation unit hygrometer and detecting that the measured temperature of the ventilation unit hygrometer is higher than the measured temperature of the indoor thermometer (that is, the ventilation unit). It may be determined that the moisture potential in the ventilation section is lower than the moisture potential in the indoor space (based on the measured temperature of the thermometer and the measured temperature of the indoor thermometer), or hygrometers may be placed in the indoor space and the ventilation section, respectively. Based on the measured values of the two hygrometers, it may be determined whether or not the moisture potential in the ventilation portion is lower than the moisture potential in the indoor space.

Then, in the summer or winter, the control unit sends the air in the ventilation unit to the space where the temperature control device takes in the air based only on the measured temperature of the ventilation unit thermometer (or the air in the ventilation unit is passed through the duct. It is not necessary to decide (to send directly to the temperature controller). For example, it is decided to compare the measured temperature of the ventilation section thermometer with the measured temperature of the thermometer that measures the temperature of the space where the temperature controller takes in air, and send the air in the ventilation section to the space where the temperature controller takes in air. Alternatively, the control unit may be designed so that the outside air temperature can be acquired, and the control unit may decide to send the air in the ventilation unit to the space where the temperature control device takes in the air based on the outside air temperature. good.

In addition, when a ventilation unit thermometer and an indoor thermometer are provided, when the measured temperature of the ventilation unit thermometer is lower than the measured temperature of the indoor thermometer by a predetermined temperature (for example, a temperature in the range of 3 to 5 ° C.) or more in summer. When the air transport device returns the air in the indoor space to the indoor space via the ventilation section, or when the measured temperature of the ventilation section thermometer is higher than the measured temperature of the indoor thermometer in winter, the air transport device Can return the air in the indoor space to the indoor space via the ventilation part.
