Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an air conditioning system that utilizes the void slab of a building to supply hot or cold air indoors and to exhaust indoor air outdoors. .

<Prior Art> Since so-called office rooms are often relatively large spaces, when installing air conditioning equipment, it is necessary to plan so that dead zones do not occur.

One of the air conditioning methods for this purpose is a method in which conditioned air inlets and outlets are provided in the ceiling, floor, etc.

FIGS. 3 and 4 are schematic configuration diagrams showing the above-mentioned conventional air conditioning system using a so-called raised floor, which is installed in, for example, a computer room.

In FIG. 3, a floor F is formed of a concrete slab, and free access floors 1 are laid on the upper surface thereof at appropriate intervals. In the space 2 formed between the floor F and the free access floor 1, a blowout duct 3 for guiding conditioned air from an air conditioning heat source device (not shown) is installed. Air outlets 3a are opened in the free access floor 1 at appropriate intervals. In addition, ceiling plates 4 are stretched over the lower surface of the concrete slab Fa at appropriate intervals on the ceiling, and a suction duct 6 is provided in the space 5 between the concrete slab Fa and the ceiling plate 4 to communicate with the outdoors or an air conditioning heat source. By arranging and connecting to the suction port 6a provided in the ceiling plate 4, indoor air is discharged to the outdoors.

In addition, in the system shown in FIG. 4, the space 2 is an underfloor chamber, and the air outlet duct 7 is opened in this underfloor chamber, and the free access floor 8 is
is used as a blowout grill for the underfloor chamber (space 2).

<Problems to be Solved by the Invention> In such a system, in order to arrange the blow-off ducts 3 and 7 on the floor F, it is necessary to lay the free access floors 1 and 8. However, when the raised floors 1 and 8 are installed, the indoor height will be affected accordingly.
This also applies to the ceiling. Therefore, in order to obtain sufficient indoor height, the entire building may become taller.

The present invention was provided in order to solve the above-mentioned conventional problems, and its purpose is to form the floors and ceilings of upper and lower floors with void slabs,
By using these voids as ventilation ducts for conditioned air to blow into the room and take in and exhaust the air from the room, the indoor space can be effectively expanded and an air conditioning system that is economical and easy to install can be obtained. .

<Means for Solving the Problems> In order to achieve the above object, the air conditioning system according to the present invention is an air conditioning system that supplies and exhausts conditioned air through the voids of a building in which upper and lower floors are partitioned by void slabs as ducts communicating with the room. In this method, a part of the above-mentioned duct is provided with an outlet as a floor duct for blowing into the indoor air on the upper floor, and the other ducts in the above-mentioned floor air duct are provided as ceiling ducts for sucking indoor air from the lower floor. It has a mouth.

In this case, a partition with an inlet on the bottom, an outlet on the wall and/or the top, and an air passage communicating between the inlet and the outlet is installed at the appropriate outlet of the floor duct. It is also possible to set

It is also possible to form a plurality of outlets on the wall surface and/or the top surface of the partition so that the locations from which the conditioned air is blown can be freely switched.

<Function> Since the voids in the void slab are directly used as conditioned air ducts, there is no need to install a special duct, and the height of the room can be increased accordingly.

Furthermore, since the conditioned air is blown out from the floor surface, when a room is partitioned with partitions, the partition can be used as a ventilation path for the conditioned air, making it possible to perform air conditioning that corresponds to free partitioning.

Furthermore, by installing conditioned air outlets in multiple locations in the partition, such as at the top and bottom, and by switching between the outlets, it is possible to set the outlet position according to the situation, and to set the optimal air conditioning for heating and cooling. You can also.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

FIGS. 1 and 2 are a front view and a side view showing the configuration of a room in a building in which the air conditioning system according to the present invention is implemented.

In the figure, 10 is a void slab, and the chamber R
This constitutes the floor 11 of the building. A void slab 10 that partitions the room R and the upper floor serves as a ceiling part 12 for the room R. The floor 11 is finished with a carpet or the like (not shown), and the ceiling section 12 has spaces 12a formed at appropriate intervals on its lower surface, and ceiling panels 13
is being spread out.

The void slab 10 has a required number of voids 10a formed within its slab thickness, and in this embodiment, a required number of linings 10b are formed in the voids 10a.
It is used as a ventilation duct for air conditioning equipment.

A part of the plurality of voids 10a is connected to an air outlet 14 provided on the floor 11 to supply conditioned air.
, and serves as a floor duct 15 for blowing air to the room R. In addition, the other void 10a that does not correspond to the air outlet floor duct 15 is used as a suction ceiling duct 16 for the room _R1 located on the lower floor with respect to the room R. It communicates with Therefore, the suction port 1 for the chamber R
7 and the suction ceiling duct 16 are similarly formed on the ceiling part 12 which also serves as the floor of the upper floor _R2 . In the illustrated example, the blowout floor duct 15 and the suction ceiling duct 16 are arranged alternately.

The air outlet 14 of the air outlet floor duct 15 is connected to the room R.
When used as a direct outlet for conditioned air to
A louver 18 is provided. The louver 18 may have a blowout amount that can be adjusted by opening and closing. This also applies to the case where the suction port 17 of the suction ceiling duct 16 is provided. In addition, as described later, if the louver 18 is not used for ballooning,
Replace with an appropriate blind cover.

The air outlet 14 is used not only for direct air blowing from the floor 11 but also for indirect air blowing. That is, depending on the environment in which the room R is used, such as a normal office, floor blowing may not be preferable. In this case, a low type partition 19 with a ventilation passage formed therein or a full size type partition 20 in contrast to the above partition 19 is used.

The partition 19 has a height comparable to the height of a person, for example, and has a conditioned air inlet 19a on the bottom, an outlet 19b on the wall, and an outlet 19c on the top to match the dimensions of the partition. An appropriate number of them are formed, and these are communicated through an internal ventilation passage (not shown). Since the opening positions of the air outlets 19b and 19c are different, for example, in order to change the air outlet position during cooling and heating, a switching damper may be provided in the air passage, and the air outlet 19b, 19c may be The louver is configured to be able to be closed. In this case, depending on the size of the partition 19, the air outlet 1
It is also possible to form only one of 9b and 19c. For example, if an air outlet is formed above the wall surface of the partition 19, the air blowing direction can be set by changing the direction of the louver.

The full-size partition 20 also has the same functions as the low-type partition 19, including an inlet 20a and an outlet 2 on the wall.
0b, but the top surface is ceiling plate 1.
3, so no air outlet is formed. However, by forming air outlets 20b ₁ and 20b ₂ at the lower and upper positions of the wall surface, respectively, it is possible to set an appropriate air blowing direction.

A ventilation opening 21 is formed in the ceiling plate 13 of the ceiling part 12 so that air from the room R can be sucked in through the suction ceiling duct 16 and discharged outside. The ventilation opening 21 is also used as an opening for mounting a lighting fixture 22.

In the above configuration, when room R is used as a large space without partitions, the conditioned air passes through the blowout floor duct 15 and is discharged from the blowout port 14 to the room R.
Speech out. In other words, the air is blown directly upward from the floor 11. As a result, the exhaust air from the room R flows from the ventilation opening 22 of the ceiling plate 13 to the space 12a suction port 17.
The air is sucked into the suction ceiling duct 16 through the suction ceiling duct 16, and is discharged to an appropriate location outside the room.

When air-conditioning the room R by partitioning it into appropriate sizes, low type or full size partitions 19 and 20 are used depending on the purpose of partitioning. The partitions 19 and 20 are erected above the air outlet 14 corresponding to the partition position.
Thereby, the blow-out floor duct 15 and the ventilation passages inside the partitions 19 and 20 communicate with each other. Therefore, in addition to being blown directly from the floor 11, the conditioned air is blown into the room from any part or all of the air outlets 19b, 19c, 20b ₁ and 20b ₂ opened in the partitions 19 and 20. It will blow out to R. In this case, the air outlet not communicating with the partitions 19, 20 may be covered with a blind cover to prevent floor air from being emitted.

<Effects of the Invention> As described above, according to the present invention, the upper and lower floors are divided by void slabs and the voids are used for conditioned air ducts, so air conditioning equipment can be installed using raised floors. Compared to other air conditioning systems, it is possible to shorten the construction period and improve workability by making work easier, and it can be constructed economically. Furthermore, the floor height can also be increased.

In particular, the outlet for conditioned air is set in the void on the floor, and the intake of room air is set in the void in the ceiling. By forming an opening, etc. and erecting it in communication with the air outlet, the partition can be used to perform air conditioning that corresponds to a free partition, and air conditioning that suits the situation from a position such as an appropriate height. be able to.
