Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having a heat storage unit filled with a heat storage agent capable of storing and releasing heat by exchanging heat with air, and contacting air in a living space with the heat storage unit through an air suction passage. The present invention relates to an air conditioner provided with a fan that circulates the air.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, a suction port 6 is provided at an upper part of a wall 8 facing a living space 1, an air outlet 14 is provided at a lower part, and a building In some cases, the heat storage body 2 and the fan 9 were provided inside the wall 8 and between the suction port 6 and the air outlet 14. In the air conditioner, for example, when the air inside the living space 1 becomes high temperature such as in the daytime, the fan 9 is operated to guide the high-temperature air to the heat storage element 2, so that the air between the high-temperature air and the heat storage element 2 Heat exchange. Then, the air that has lost heat energy and has become low temperature is returned to the living space 1 from the outlet 14 again, thereby maintaining the internal temperature of the living space 1 at a comfortable temperature. On the other hand, when the temperature of the air inside the living space 1 becomes low at night, the fan 9 is operated to guide the low-temperature air in the living space 1 from the suction port 6 to the heat storage body 2, The heat is again exchanged between the air and the heat storage body 2, and the warmed air is returned to the living space 1 from the outlet 14 again, so that the interior temperature of the living space 1 is also maintained at a comfortable temperature.

[0003]

However, the above-mentioned conventional air conditioner has the following problems. That is, each of the suction port 6 and the air outlet 14, the heat storage body 2, the fan 9, and the wall 8 that constitute the air conditioning equipment is often configured as a series of units. In many cases, the suction port 6 and the air outlet 14 are provided in a state where they are opened in advance in a member constituting the wall 8. For this reason, especially, the suction port 6 formed above the wall member becomes conspicuous from inside the living space 1, and the interior of the living space 1 may be impaired. In addition, since the suction port 6 has a configuration that opens in the up-down direction X, the suction port 6 has the highest temperature among the high-temperature air in the living space 1 although it is provided as high as possible in the wall 8. It was not possible to suck only the air that had flowed, and in addition to the air that had reached the highest temperature, air had to be sucked at a low temperature to some extent at the same time. For this reason, heat exchange in the heat storage body 2 could not be performed most efficiently. Furthermore, in the conventional air conditioning equipment, the living space 1
Therefore, in order to increase the internal temperature of the living space 1, it was necessary to open the curtain 4 during the day. However, when the curtain 4 is opened, inconveniences such as discoloration of furniture due to ultraviolet rays occur, and the inside of the living space 1 is easily seen from the outside, which is not preferable in terms of crime prevention. SUMMARY OF THE INVENTION An object of the present invention is to provide an air-conditioning system that solves such disadvantages of the related art, enables efficient air-conditioning of a living space, and can improve the interior appearance of the living space.

[0004]

According to a first aspect of the present invention, there is provided an air conditioner for taking air from a living space of the building into an air suction path and bringing the air into contact with the heat storage body. A suction port is arranged in a curtain box, and an air outlet for returning the air after contacting the heat storage body to the living space again is a skirting board below the wall, or
The feature is that it is arranged on at least one of the floors. (Operation / Effect) As in this configuration, by providing a suction port in the curtain box and providing an outlet in the baseboard or floor,
These suction ports and air outlets are made inconspicuous, and the interior of the living space can be improved. In addition, with this configuration, the heat utilization efficiency is improved. For example, when a user of a building goes out during the day, a curtain provided on a window of a living space is often closed. In this case, the curtain is heated by the solar radiation, and the air near the surface of the curtain also has a high temperature and flows upward. In this configuration, since the air suction port is provided inside the curtain box, it is possible to suck this high-temperature air and guide it to the heat storage body.
On the other hand, when using the heat stored in the heat storage body at night or the like,
Since the air warmed by the heat storage body is blown into the living space through an outlet provided on the baseboard or floor, the warmed air can be supplied to the lower part where the temperature in the living space is lowest. Therefore, the heating effect in the living space can be improved. Further, as described above, in the case of this configuration, high-temperature air can be guided to the heat storage body even when the curtain is closed. Therefore, unlike a conventional air conditioner, it is not necessary to keep the curtain open during the daytime, so that inconveniences such as discoloration of furniture in the room due to ultraviolet rays can be prevented, and it is also preferable in crime prevention.

(Configuration 2) As described in claim 2, the air conditioner of the present invention can be configured by arranging the heat storage body at least under the ceiling, inside the wall, or under the floor. (Operation / Effect) In this configuration, for example, when a heat storage body is provided inside a wall, the heat storage body can be provided at a position close to the curtain box, so that high-temperature air in a living space can be easily introduced. Thus, the heat of the high-temperature air can be effectively stored. In addition, when the heat storage body is provided inside the wall, the heat storage wall can be manufactured as a unit in a factory or the like in advance, and the labor required when actually constructing the building can be greatly reduced. On the other hand, when the heat storage body is provided under the floor behind the ceiling, the wall thickness can be reduced compared to a conventional air conditioner in which the heat storage body is provided inside the wall.
A larger living space can be secured.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the air conditioner of the present invention. The air conditioner stores heat of the air in the living space 1 heated by, for example, daytime sunlight, that is, heat energy of the indoor air in the heat storage unit 2 and heats the living space 1 at night or the like. The heat storage of the body 2 is supplied to the living space 1 again.

In the present invention, air heated near the curtain 4 provided in the window 3 is used as the heated air in the living space 1. For example, when the resident goes out during the daytime, the curtain 4 is usually closed. In this case, the curtain 4 is heated by the solar radiation and the curtain 4 is closed.
The air existing between the window 3 and the window 3 is heated to a high temperature. As shown in FIG. 1, a suction port 6 is provided inside a curtain box 5 for suspending the curtain 4 in order to use the high-temperature air. If the suction port 6 is formed over substantially the entire length of the curtain width, a large amount of high-temperature air can be taken in, which is convenient. The high-temperature air taken in from the suction port 6 passes through the air suction path 7 and
And heat exchange is performed by contact with the heat storage body 2. As shown in FIG. 1, for example, the heat storage body 2 is installed in a wall 8 adjacent to a surface on which the window 3 is formed among side surfaces of a building.
This is because with this configuration, a large laying area of the heat storage body 2 can be secured. The air suction path 7 is provided with a fan 9 for guiding high-temperature air to the position of the heat storage unit 2 and contacting the heat storage unit 2.

The heat storage body 2 is filled with a heat storage agent 2a capable of storing and releasing heat by exchanging heat with the high-temperature air. As the heat storage agent 2a, for example, a mixture of calcium chloride hydrate and water, or a material utilizing latent heat that undergoes phase transformation with heat absorption / release such as various low melting point plastics, paraffins, and wax is used. May be
Materials that simply use sensible heat, such as stone, various metals, and cement boards, may be used. In the case of the former substance using latent heat, for example, a phase transformation is set at a temperature of about 20 ° C. When using latent heat, heat absorption and
A large amount of emission can be secured. On the other hand, in the case of the latter substance using sensible heat, troubles such as leakage of the heat storage material can be reliably prevented. In order to enhance the heat storage effect, the wall 8 may be constituted by a heat storage wall 8a.
The heat storage wall 8a is configured by, for example, providing a panel member 10 integrally formed of a cement-based material inside the wall 8, for example. Inside the panel member 10, the heat storage body accommodation space 11 penetrating in the vertical direction X, and the heat storage body accommodation space 1
1, an air suction passage 7 for sucking indoor air, and an air blowing passage 12 for exchanging heat with the heat storage body 2 provided inside the heat storage body housing space 11 and then blowing the sucked room air into the living space 1.
Is formed in advance. Thus, the heat storage body 2 is provided inside the wall 8.
In the case of using a structure including the above, it can be manufactured in advance as a unit in a factory or the like, so that the labor for actually constructing the building can be greatly reduced.

On the other hand, the air that has exchanged heat with the heat storage body 2 is provided, for example, on a baseboard 13 below the wall 8 through an air blowing passage 12 provided below the heat storage body 2. The air is discharged from the outlet 14 into the living space 1. Thus, the outlet 1
The reason why 4 is provided on the baseboard 13 is that, for example, at night,
When utilizing the heat stored in the heat storage body 2 in the daytime, the air heated by the heat storage body 2 is supplied to the lower part of the living space 1 where the temperature is lowest, thereby heating the living space 1. It is because it can raise. The outlet 14 is provided with a lid member 15 that can be opened and closed. This is because, for example, after all the heat stored in the heat storage body 2 is consumed, if the outlet 14 is maintained in the open state, the cool air near the inner surface of the wall 8 cooled by the outside air is discharged. This is because the air enters the interior of the living space 1 from the outlet 14 and the interior of the living space 1 cannot be maintained at an appropriate temperature. Further, the fan 9 may be provided in the air blowing passage 12 in addition to the structure provided in the air suction passage 7.

(Effect) With the air conditioner of the present invention, the air inside the living space 1 heated by the sunshine is stored in the heat storage body 2.
Since the heat is stored and the heat is released at night, the air conditioning of the living space 1 can be efficiently performed, and for example, the amount of heat required for heating the living space 1 can be reduced. Further, the air conditioner of the present invention provides a suction port 6 for guiding the air in the living space 1 to the heat storage element 2 inside the curtain box 5 and re-uses the air after contacting the heat storage element 2 with the living space. Air outlet 1 to return to 1
The suction port 6 and the air outlet 14 can be made inconspicuous inside the living space 1 because the base 4 is provided on the baseboard 13 formed below the wall 8.
The interior of the living space 1 can be improved as compared with the air conditioner provided on the wall 8. Further, as described above, in the case of this configuration, even when the curtain 4 is closed, the high-temperature air can be guided to the heat storage body 2, so that the curtain 4 is always opened and opened during the day like a conventional air conditioner. It is not necessary to keep it, and it is possible to prevent inconvenience such as discoloration of furniture in the room due to ultraviolet rays, and it is also preferable for crime prevention.

Has a configuration that penetrates through the inside of the wall 8, it is necessary to prevent the temperature from dropping while the room air passes through the air suction path 7. Therefore, a heat insulating material is provided on the wall 8 to form a heat insulating wall structure. In the case of this configuration, the thickness of the wall 8 can be made smaller than that of an air conditioner in which the heat storage body 2 is provided inside the wall 8, so that the living space 1 can be secured more widely. In this case, as shown in FIG.
If the outlet 14 is provided on the floor 18, it is possible to prevent the air inside the air suction path 7, which has a low temperature at night, for example, from directly entering the living space 1. If the air outlet 14 is provided with an openable / closable lid member 15, the intrusion of cool air can be more reliably prevented.

<3> In the above embodiment, the air outlet 1

The upper edge of the switching valve 20 abuts on the inner surface of the curtain box 5 on the opposite side to the living space 1 or on the inner surface on the living space 1 side. As a result, the suction port 6 is The curtain 4 can communicate with either the side opposite to the living space 1 or the side of the living space 1. The switching valve 2
0 is operated by the switching means 21 provided on the wall 8 or the like. The operation may be configured to be performed manually or may be configured to be performed automatically. For example, when a resident goes out in the daytime, the curtain 4 is usually closed in many cases. At this time, if the curtain 4 is in a state of receiving solar radiation,
The outside of the curtain 4 becomes particularly hot. In this case, the switching valve 20 is tilted toward the living space 1, and the suction port 6 is communicated with the curtain 4 to the outside, so that high-temperature air can be guided to the heat storage body 2. On the other hand, when heating the living space 1 at night using the heat storage stored in the heat storage body 2 during the day, the switching valve 20 is tilted to the opposite side to the living space 1 and the suction port 6 is set to the curtain 4. To the living space 1 side. In other words, when the heating is performed, air heated by the heat storage of the heat storage body 2 is blown out to the living space 1 from the air outlet 14 provided in the baseboard 13 or the like. From the heat storage body 2
The air will be sucked toward. At this time, in order to prevent the heat storage body 2 from being excessively cooled, the curtain 4
