This is because a hollow layer in which air flows vertically between the outer side material and the inner side material allows ventilation by the chimney effect, and enables natural ventilation to the room using the hollow layer. It is.

JP 2011-219989 A

  However, the double skin curtain wall shown in Patent Document 1 does not necessarily have a sufficient chimney effect because the hollow layer is divided into a plurality of layers, and no special heat shielding measures are taken in itself. Therefore, a sufficient energy saving effect cannot be expected.

That is, in the conventional double skin curtain wall, solar radiation passes through the glass surface as the outer side surface material and the inner side surface material and enters the room as it is.
Moreover, not only the air in the hollow layer becomes high temperature due to solar radiation, but also the double skin curtain wall itself (that is, the glass surface as the outer side member and inner side member constituting the double skin curtain wall and for attaching them) The whole of the sash etc.) becomes excessively hot, so the hot air in the hollow layer flows into the room through the internal ventilation port, or the outside air introduced into the room through the duct of the external ventilation port is heated to a high temperature, It is assumed that not only the energy saving effect is not obtained but also the cooling load increases.

  In view of the above circumstances, the present invention further improves the double skin curtain wall disclosed in Patent Document 1 to realize an effective and appropriate double skin curtain wall that provides a sufficient energy saving effect, and also includes the double skin curtain wall. The purpose is to provide an effective air conditioning system to be applied to a building.

An inner surface member provided at an interval on the inner side, and a hollow layer communicating in the vertical direction is provided between the outer surface member and the inner surface member, and the lowermost layer and the uppermost portion of the hollow layer are provided. A lower ventilation opening and an upper ventilation opening that are open to the outside are provided, respectively, and at least a part of the outer side surface material and the inner side surface material is a window portion made of a glass material, and the hollow layer has a position at the window portion A solar radiation shielding material is provided, and for each of the levels, an indoor ventilation mechanism is provided for directly ventilating the room between the room and the outdoors. The external ventilation opening that opens in the room An internal vent to the mouth, and characterized by being installed across said hollow layer constituted by ventilation duct for connecting the internal vent to the outside vent.

  The invention according to claim 2 is the double skin curtain wall according to claim 1, wherein an exhaust mechanism for exhausting indoor air in each layer to the hollow layer is provided for each of the layers. It is characterized by becoming.

  Invention of Claim 3 is an air-conditioning system applied to the building provided with the double skin curtain wall of Claim 1 or 2, Comprising: Air-conditioning equipment for performing air-conditioning operation | movement, taking in external air with respect to each hierarchy And an exhaust system for exhausting air from each level, wherein the air conditioning system is configured to be able to introduce at least part of the introduced outside air through the hollow layer in the double skin curtain wall, and the exhaust system Is configured such that at least a part of the exhaust from the room can be exhausted to the hollow layer in the double skin curtain wall, and the air conditioning equipment, the exhaust equipment, and the indoor ventilation installed in the double skin curtain wall. The mechanism is configured to be capable of air-conditioning operation and outdoor air-cooling operation for each level. That.

According to the double skin curtain wall of the present invention and the air conditioning system using the double skin curtain wall, the heat load from the outer wall surface and the window surface can be greatly reduced, and the cooling and heating energy consumption can be reduced. In particular, in the summer, solar radiation acquisition from the window can be sufficiently reduced by the solar radiation shielding material.

It is a figure which shows the example of an operation pattern similarly. It is a figure which shows the example of the driving | running pattern for every same season. It is a figure showing an embodiment of an air-conditioning system of the present invention.

Hereinafter, embodiments of the double skin curtain wall and the air conditioning system of the present invention will be described.
FIG. 1 shows a basic first embodiment of a double skin curtain wall 1 of the present invention. The double skin curtain wall 1 according to the present embodiment is attached to the outer wall portion of a multi-layered building over each level to constitute the outer wall surface of the building, and is basically the same as that shown in Patent Document 1. Are provided with an outer surface material 2 and an inner surface material 3 provided at an interval on the indoor side of the outer surface material 2, and communicated in the vertical direction between the outer surface material 2 and the inner surface material 3. Thus, the hollow layer 4 through which air can flow is provided.

In the double skin curtain wall disclosed in Patent Document 1 described above, the hollow layer is divided into a plurality of layers, and a lower ventilation port and an upper ventilation port are provided for each division. The curtain wall 1 is not provided with such a section, and is provided with a lower ventilation port 5 and an upper ventilation port 6 that open to the outdoors only at the lowermost part and the uppermost part of the entire hollow layer 4.
Therefore, in the double skin curtain wall 1 of the present embodiment, a chimney effect is generated in the entire hollow layer 4, and outside air flows into the hollow layer 4 from the lowermost lower ventilation port 5, and flows from the uppermost upper ventilation port 6 to the outside. A series of updrafts over the entire hollow layer 4 is surely formed to flow out, so that the air in the hollow layer 4 and the double skin even if the hollow layer 4 is naturally well ventilated and exposed to sunlight in summer. The curtain wall 1 itself is prevented from becoming too hot.

  In addition, it is also preferable to provide an appropriate opening / closing mechanism in both or one of the lower ventilation port 5 and the upper ventilation port 6, and it is also preferable to provide an opening degree adjusting mechanism in the opening / closing mechanism. Thereby, it is possible to close the lower ventilation port 5 and the upper ventilation port 6 to stop the ventilation in the hollow layer 4 as necessary, or to adjust the ventilation amount appropriately.

Further, in the double skin curtain wall 1 of the present embodiment, at least a part of the outer side surface material 2 and the inner side surface material 3 is a window portion 7 made of a daylightable glass material.
In the case of the illustrated example, the range facing the interior of each floor is a window portion 7 made of a transparent glass material, and the space between the upper and lower window portions 7 is a waist portion 8. The material of the waist portion 8 is arbitrary, but when the entire double skin curtain wall 1 is entirely made of a glass curtain wall, the waist portion 8 may be formed of a transparent or opaque glass material.

And the solar radiation shielding material 9 which consists of blinds, for example is provided in the position of the window part 7 in the hollow layer 4 in the double skin curtain wall 1, The window is operated by operating the solar radiation shielding material 9 as needed. The amount of solar radiation that enters the room through the unit 7 can be controlled.
In addition, it is preferable to use pair glass, Low-E glass or the like on which a heat ray reflective film is formed as a glass material provided on at least the inner surface material 3, thereby further improving the heat insulating performance in the window portion 7. It is possible.

Furthermore, the double skin curtain wall 1 of the present embodiment is provided with an indoor ventilation mechanism 10 for performing ventilation directly between the room and the outdoors with respect to each level.
The indoor ventilation mechanism 10 in the present embodiment is installed in an external ventilation port 11 that opens to the outer side face material 2, an internal ventilation port 12 that opens to the ceiling surface of the room, and the hollow layer 4. The ventilation duct 13 connects the ventilation opening 11 and the internal ventilation opening 12, and outside air is directly taken into the room as needed by the room ventilation mechanism 10, or conversely, the room air is directly taken outdoors. Exhausted.

It is preferable that a plurality of such indoor ventilation mechanisms 10 be provided on each surface of the outer wall surface, thereby causing inflow of outside air or outflow of room air into any of the indoor ventilation mechanisms 10 according to weather conditions such as wind direction and wind force. Natural ventilation is thereby effectively produced.
Further, in order to secure the amount of outside air flowing into the room through the room ventilation mechanism 10, a void space (for example, a void 40 described later) is provided in the building, and the chimney effect generated there is used to create the room ventilation mechanism. It is also preferable to induce outside air into the building through 10.

  In addition, since the indoor ventilation mechanism 10 of this embodiment is the structure which connected the external ventilation port 11 and the internal ventilation port 12 with the ventilation duct 13, the air in the hollow layer 4 is high temperature by solar radiation in the summer or middle period. However, the high temperature air does not flow directly into the room. However, since the outside air introduced into the room through the ventilation duct 13 may be heated by the high-temperature air in the hollow layer 4 when passing through the ventilation duct 13, it is necessary to prevent this. It is preferable to cover the ventilation duct 13 with a heat insulating material.

  The indoor ventilation mechanism 10 is preferably provided with an appropriate opening / closing mechanism, and the opening / closing mechanism is preferably provided with an opening adjustment mechanism. By operating the opening and closing mechanism as necessary, ventilation by the indoor ventilation mechanism 10 can be freely performed only when necessary. If ventilation is not necessary, the opening and closing mechanism may be closed. It is also possible to adjust the ventilation volume appropriately if necessary.

According to the double skin curtain wall 1 of the present embodiment, the lower ventilation port 5 is provided only at the lowermost portion of the hollow layer 4 and the upper ventilation port 6 is provided only at the uppermost portion as described above. As a result, the upward flow due to the chimney effect is surely generated and sufficient ventilation is naturally performed. Therefore, the air in the hollow layer 4 may become excessively hot due to solar radiation, or the double skin curtain wall 1 itself may become excessively hot. Absent.
Therefore, according to the double skin curtain wall 1 of the present embodiment, a sufficient energy saving effect can be obtained as compared with the conventional double skin curtain wall disclosed in Patent Document 1, and the lower ventilation opening 5 and the upper ventilation opening 6 are respectively provided. The construction cost can be reduced because it is sufficient to provide one place at a time.

  Further, since the sunscreen material 9 such as a blind facing the window 7 is incorporated in the double skin curtain wall 1, the double skin curtain wall 1 itself can control the solar radiation in the room. In this case, the energy saving effect is excellent, and it is not necessary to provide other solar radiation control means in the room.

  Furthermore, since the indoor ventilation mechanism 10 is provided at each level, natural ventilation by the indoor ventilation mechanism 10 is possible in an intermediate period or the like, and the indoor ventilation mechanism 10 is indoors and outdoors without the hollow layer 4 being interposed. Therefore, even if the air in the hollow layer 4 becomes high temperature in the middle period, the high-temperature air is not introduced into the room as it is.

FIG. 2 schematically shows an example of the air conditioning operation pattern for each season using the double skin curtain wall 1 of the first embodiment. In addition, illustration of the solar radiation shielding material 9 is abbreviate | omitted in FIG.
As shown in FIG. 2, the hot air in the hollow layer 4 can be efficiently discharged by opening the lower ventilation port 5 and the upper ventilation port 6 at the time of cooling in summer. The entire curtain wall 1 can be prevented from becoming excessively hot.
By closing the lower ventilation port 5 and the upper ventilation port 6 during heating in winter, the entire double skin curtain wall 1 can be substantially sealed and its heat insulation can be improved.
In the intermediate period, natural ventilation using the indoor ventilation mechanism 10 is possible. In this case, if the void 40 is provided in the building as shown in the figure, the indoor air is exhausted by the chimney effect generated in the void 40, and accordingly, the outside air is induced into the building through the indoor ventilation mechanism 10, More effective natural ventilation is possible.

Conventionally, it has been practiced to provide a void inside a building and use it for exhausting natural ventilation, but sufficient natural ventilation cannot be expected simply by providing only a void.
That is, as shown in FIG. 3, when the void 40 is simply provided without providing the double skin curtain wall 1, the outside air temperature θ 0 , the room temperature θ R , and the void inside temperature θ B are set, and the outside air density ρ 0 , Assuming that the indoor density ρ R and the void internal density ρ B , a relationship of θ 0B ≦ θ R , ρ 0B ≦ ρ R occurs between them, and the pressure gradient in the outside air, the room, and the void is Each is in the state shown in the figure.
Therefore, if the pressure difference ΔP 1 between the outside air and the room, and the pressure difference ΔP 2 between the void and the room, a floor where ΔP 1 + ΔP 2 ≦ 0 occurs on the upper floor, which is effective in a state where wind power cannot be expected. Ventilation is not possible.
Therefore, it is not effective to simply provide the void 40 without providing the double skin curtain wall 1, and it is effective to provide the void 40 after providing the double skin curtain wall 1 as described above.

Although the basic first embodiment of the present invention has been described above, the following modifications can be considered in the present invention.
In the double skin curtain wall 1 of the above-described embodiment, as schematically shown in FIG. 1, the configuration of the indoor ventilation mechanism 10 installed at each level is configured such that the external ventilation port 11 is directly connected to the outer face material 2. The ventilating duct 13 is installed straight so as to cross the hollow layer 4 while being installed so as to open. Alternatively, for example, a modification as shown in FIG. 4 is also conceivable.
This is because the external ventilation port 11 has a horizontally long slit shape and a chamber 13a which is a part of the ventilation duct 13 is provided on the inside, and the original ventilation duct 13 is connected to the chamber 13a. The opening area of the external ventilation port 11 can be increased to ensure a sufficient amount of ventilation.

Moreover, in the double skin curtain wall 1 of this invention, in addition to providing the indoor ventilation mechanism 10 for ventilating between indoors and outdoors like the said 1st Embodiment, 2nd implementation shown in FIG. It is also preferable to provide an exhaust mechanism 15 for exhausting air from the room to the hollow layer 4 of the double skin curtain wall 1 as in the embodiment.
In the case where such an exhaust mechanism 15 is provided, it is preferable that the exhaust mechanism 15 is also provided with an appropriate opening / closing mechanism and opening degree adjusting mechanism, so that the exhaust from the room to the hollow layer 4 is performed freely only when necessary. It is also possible to adjust the displacement appropriately.

FIG. 6 shows an operation pattern when natural ventilation is performed using the double skin curtain wall 1 of the second embodiment provided with the exhaust mechanism 15.
In this case, both the indoor ventilation mechanism 10 and the exhaust mechanism 15 are opened, outside air is taken in by the indoor ventilation mechanism 10, and exhaust is performed by the exhaust mechanism 15.
In this case, it is preferable to minimize the pressure loss at the upper ventilation port 6 by opening the opening area of the upper ventilation port 6 of the hollow layer 4 larger than the cross-sectional area of the hollow layer 4. Moreover, it is preferable to maximize the pressure loss at the lower ventilation port 5 so that the lower ventilation port 5 is closed or slightly opened.
Moreover, it is preferable that the upper ventilation port 6 is installed inside the lower part of the roof crown wall 2a formed by raising the outer face member 2 upward so as to receive negative wind pressure.

In this case, assuming that the outside air temperature θ 0 , the room temperature θ R , and the temperature θ d in the hollow layer, and the outside air density ρ 0 , the room density ρ R , and the density ρ d in the hollow layer, θ 0 < A relation of θ Rd , ρ 0 > ρ R > ρ d is generated, and a pressure gradient as shown in the figure is generated.
Then, the pressure difference [Delta] P 1 between the outside air and the chamber when the pressure difference [Delta] P 2 of the indoor and the hollow layer 4, all of ΔP 1 + ΔP 2 downstairs> 0, therefore the outside air from the room ventilation system 10 in a room flows, Natural ventilation of exhausting from the exhaust mechanism 15 is performed.
Furthermore, when wind blows and a negative wind pressure ΔP 3 is applied to the upper ventilation opening 6 (ΔP 3 <0),
Since ΔP 1 + ΔP 2 −ΔP 3 >> 0, a large amount of natural ventilation can be obtained.

In the double skin curtain wall 1 of the second embodiment, in addition to the basic operation pattern as shown in FIG. 2 by the double skin curtain wall 1 of the first embodiment, air conditioning for each season as shown in FIG. Driving patterns are also possible. In addition, illustration of the solar radiation shielding material 9 is abbreviate | omitted in FIG.
That is, at the time of cooling in summer, the exhaust air is guided to the desiccant air conditioner 50 installed on the roof by the high-temperature air from the upper ventilation opening 6 of the double skin curtain wall 1, so that the desiccant rotor of the desiccant air conditioner 50. Can be used for playback. This operation pattern can be similarly applied to the double skin curtain wall 1 of the first embodiment.
At the time of heating in winter, the external air load can be reduced by introducing high-temperature air from the upper ventilation opening 6 of the double skin curtain wall 1 to the external air conditioner 60. This operation pattern can be similarly applied to the double skin curtain wall 1 of the first embodiment.
In the intermediate period, natural ventilation using the indoor ventilation mechanism 10 and the exhaust mechanism 15 is possible as shown in FIG. In this case, by providing the void 40 in the building as in the case of the first embodiment, more effective natural ventilation using the chimney effect by the void 40 is possible.

When the exhaust mechanism 15 is provided as in the second embodiment, the indoor ventilation mechanism 10 may be dedicated to indoor air supply, and in that case, it is indicated by a broken line in FIG. It is also conceivable to incorporate an air supply fan 16 in the ventilation duct 13 as shown in FIG.
When the outside air is taken in by the air supply fan 16 and the outside air temperature is too low in the winter, the room air and the outside air are appropriately mixed and adjusted to an appropriate temperature as needed, and then introduced into the room. It is also preferable to do.

The embodiment of the double skin curtain wall 1 of the present invention has been described above. Next, an embodiment of the air conditioning system of the present invention will be described with reference to a schematic system diagram shown in FIG. In addition, illustration of the solar radiation shielding material 9 is abbreviate | omitted in FIG.
The air conditioning system 20 of the present embodiment is applied to a building having the double skin curtain wall 1 of the first embodiment shown in FIG. 1 and the double skin curtain wall 1 of the second embodiment shown in FIGS. An air conditioner 21 for performing a cooling / heating operation while taking outside air into each level, and an exhaust unit 26 for exhausting air from each level, and in the middle period, etc. The cooling operation is possible.

The air conditioning equipment 21 in the present embodiment supplies the air supply (SA) adjusted by the air conditioner 22 as usual through the air supply duct 23 into the room and returns the return air (RA) from the room to the air conditioner 22. In this case, a predetermined amount of outside air (OA) is taken in through the outside air duct 24 by the outside air fan 30 and can be treated outside.
And in the air conditioner 21 of this embodiment, sub external air duct 25 (shown with a broken line) so that at least one part of the external air introduce | transduced into the air conditioner 22 can be introduce | transduced through the hollow layer 4 of the double skin curtain wall 1. FIG. Is connected to the top of the double skin curtain wall 1 so that the outside air can be introduced into the air conditioner 22.
In the illustrated example, the air conditioner 22 is illustrated as being capable of processing both the indoor load and the outdoor air load. However, the air conditioner 22 may be an indoor load processing dedicated machine and an external air conditioner (outdoor air processing dedicated machine: FIG. (In this case, the outside air fan 30 and the sub outside air duct 25 may be connected to the outside air conditioner.)

  The exhaust facility 26 exhausts air from the room to the outdoors by the exhaust fan 27 and the exhaust duct 28. However, in the exhaust facility 26 of the present embodiment, at least a part of the exhaust is passed through the sub exhaust duct 29 (shown by a broken line) and double skin. The hollow wall 4 of the curtain wall 1 can be evacuated.

  In the air conditioning system 20 of the present embodiment, not only the cooling operation in summer and the heating operation in winter, but also the outside air cooling operation by all the outside air is possible in the intermediate period and the like, and the double skin curtain wall 1 is used as follows. By selecting an appropriate operation pattern, efficient air-conditioning operation is possible throughout the year.

  That is, during the cooling operation in the summer or the intermediate period, at least part of the indoor air to be exhausted by the exhaust fan 27 is exhausted to the hollow layer 4 of the double skin curtain wall 1 through the sub exhaust duct 29, thereby It is possible to prevent the inside of the skin curtain wall 1 from becoming excessively hot.

  During the heating operation in winter, when the inside of the hollow layer 4 of the double skin curtain wall 1 is heated by solar radiation and is higher than the outdoor temperature, the heated air in the hollow layer 4 is transferred to the double skin curtain wall 1. By introducing the air conditioner 22 (or an external air conditioner) from the top through the sub external air duct 25, it is possible to reduce the external air load.

When the outside air cooling operation is performed in an intermediate period or the like, the amount of outside air introduced by the outside air fan 30 or the amount of exhaust by the exhaust fan 27 can be reduced by using the indoor ventilation mechanism 10 provided in the double skin curtain wall 1 together. it can.
That is, if the outside air introduction amount by the outside air fan 30 is made smaller than the amount of exhaust air by the exhaust fan 27 or the outside air fan 30 is stopped, the outside ventilation mechanism 10 naturally introduces the outside air into the room. Conversely, if the amount of exhaust by the exhaust fan 27 is made smaller than the amount of outside air introduced by the outside air fan 30 or if the exhaust fan 27 is stopped, excess room air is naturally exhausted outdoors by the room ventilation mechanism 10. Therefore, in any case, the power consumption of the outside air fan 30 or the exhaust fan 27 can be reduced.

Even when the exhaust mechanism 15 is installed as in the double skin curtain wall 1 of the second embodiment shown in FIG. 5 or the air supply fan 16 is provided to the indoor ventilation mechanism 10, these exhaust mechanisms are provided. 15 and the indoor ventilation mechanism 10 can be linked to the air conditioning system 20 in the same manner, so that efficient operation is possible.
In addition, the indoor ventilation mechanism 10 and the exhaust mechanism 15 are preferably used for natural ventilation in the intermediate period as in the above embodiment, but if necessary, the indoor ventilation mechanism 10 can be used during cooling or heating. Alternatively, the exhaust mechanism 15 may be used in cooperation with the air conditioning equipment 21 or the exhaust equipment 26.
Further, in FIG. 8, the air conditioning equipment 21 and the exhaust equipment 26 are schematically illustrated as being installed at each level. However, the specific configurations, equipment capacities, zoning settings, and the like of the air conditioning equipment 21 and the exhaust equipment 26 are illustrated. The specifications may be arbitrarily designed according to the size and application of the building. For example, the air conditioner 22 and the exhaust fan 27 are installed on the roof as a central system without being limited to the illustrated example. Naturally, various design changes and applications are possible without departing from the scope of the present invention.
