Abstract

PURPOSE:To effectively increase an indoor space by a method wherein a discharge port is formed in a part of a duct serving as a floor duct for discharge connected to the interior of a room at an upper floor next to a current floor, and a suction port is formed in other duct serving as a ceiling duct for suction of indoor air in a room at a lower floor next to the current. CONSTITUTION:Since a part of a plurality of voids 10a forms the feed side for conditioning air, the void is communicating to a discharge port 14 formed in a floor 11 and forms a floor duct 15 for discharge connected to a room R. Other void 10a not responding to the duct 15 for discharge is communicating to a suction port 17 opened to the lower floor side so as to utilize the duct as a ceiling duct 16 for suction connected to a room R1 positioned on a lower floor next to the room R. Thus, the suction port 17 to the room R and the ceiling duct 16 for suction are formed in a similar manner described above in a ceiling port 12 forming the floor of an upper floor R2. The floor duct 15 for discharge and the ceiling duct 16 for suction are alternately disposed, that is since a void 10a of a void slab 10 is utilized as a duct for conditioning air as it is, there is no need to install a special duct, and the height of the interior of a room can be increased by a size equivalent to the size of the special duct.

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 will not occur.

One type of air conditioning system for this purpose is to provide intake and outlet ports for conditioned air in the ceiling, floor, etc.

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

In FIG. 3, the floor F is formed of a concrete slab, and free access floors I are laid on the upper surface thereof at appropriate intervals. An air conditioning heat source 11 (not shown) is installed in the space 2 formed between the floor F and the raised floor 1.
A blowout duct 3 is disposed for supplying conditioned air from the air conditioner 1 to the blowout duct 3, and a blowout port 3a is opened to the free access floor l at an appropriate interval from the blowoff duct 3. In addition, ceiling boards 4 are stretched on the lower surface of the concrete slat Fa at appropriate intervals on the ceiling, and the concrete slat Fa and the ceiling board 4 are
A suction tact 6 that communicates with the outdoors or an air conditioning heat source device is arranged in the space 5 between the ceiling plate 4 and the suction tact 6, which is connected to the suction port 6a provided in the ceiling plate 4, thereby discharging indoor air to the outside. ing.

In addition, in the system shown in FIG. 4, the space 2 is an underfloor chamber, the blowing tact 7 is opened in this underfloor chamber, and the free access floor 8 is connected to the underfloor chamber (
It is designed to be used as a blowout crease function for space 2).

<Problem to be solved by Hatsuho> In such a system, in order to arrange the blowing tact 3.7 on the floor F, it is necessary to lay 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, and to create ventilation ducts for conditioned air in the voids. By using the air-conditioning system to blow air into the room and take in and exhaust 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 provides conditioned air supply/exhaust using a duct that connects the two voids of a building with upper and lower floors partitioned by void slabs to the interior of the building. In this air conditioning system, some of the above ducts are provided with air outlets as floor ducts for blowing air into the room on the upper floor, and other ducts other than the above air outlet duct are used as ceiling ducts for sucking indoor air from the lower floor. It is equipped with a suction port.

In this case, an inlet is formed on the bottom surface, an outlet is formed on the wall surface and/or the upper surface, and a partition with an air passage communicating between the inlet and the outlet is erected at the appropriate outlet of the floor duct. You can also do that.

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

<Function> By using the voids of the void slab as they are as ducts for conditioned air, there is no need to install a special duct, and the height of the room can be increased accordingly.

In addition, since the conditioned air is blown out from the floor surface, when partitions are used to partition the room, the partitions can be used as ventilation paths for the conditioned air, allowing air conditioning to be performed freely in accordance with the partitions.

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 during heating and cooling. You can also do it.

<Example> Embodiments of the present invention will be described below 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 floor 11 of room R
Configure. The void slab 10 that partitions the room R and the upper floor is connected to the ceiling 12 of 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 a ceiling board 13 is stretched over the ceiling section 12.

The void slab 10 has a required number of voids 10a formed within its slab thickness, and in this embodiment, a required lining lOb is applied to the voids 10a to serve as a ventilation tact for the air conditioner.

A part of the plurality of voids 10a communicates with an air outlet 14 provided on the floor 11 to serve as a supply side of conditioned air.
A floor duct 15 for blowing air is provided. In addition, another void IOa that does not correspond to the outlet river bed duct 15 is an inlet 1 opened on the lower floor side in order to be 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 7. 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.

When the air outlet 14 of the air outlet floor duct 15 is used to directly blow out conditioned air into the room R, 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.

Further, as will be described later, when the louver 18 is not used for blowing air, the louver 18 is replaced 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 an air passage formed therein, or a full size type partition 20 in contrast to the above partition 19, may be used.
Take advantage of.

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 appropriate number of outlets 19c on the top depending on the partition dimensions. These are communicated through an internal ventilation passage (not shown). Since the opening positions of the air outlets 19b and 19c are different, the air outlet 19b and 19c may be switched to each other and provided with a damper so that the air outlet position can be changed between cooling and heating, for example. The louver 19c is configured to be closeable. In this case, partition 19
Depending on the size, it is also possible to form only one of the air outlets 19b 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, with an inlet 20a and an outlet 20b on the wall, or the upper surface comes into contact with the ceiling plate 13, so an outlet is not formed. do not have. However, by forming the air outlets 20t)+ and 20b2 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,
The air in the room R is sucked in through a suction ceiling duct 16 and can be discharged to the outside. And this ventilation opening 2
1, the lighting fixture 22 is installed so that it can also be used as an opening.

In the above configuration, when room R is used as a large space without partitions, conditioned air is distributed through the blowout floor duct 1.
5 and blows out into the chamber R from the blow-off port 14. That is, floor 1
This is a direct upward blowout from 1. As a result, room R
The exhaust air is discharged from the ventilation opening 22 of the ceiling plate 13 to the space 12a.
The air is sucked into the suction ceiling duct 16 through the suction port 17 and discharged to an appropriate location outside the room.

When air conditioning is performed by partitioning the room R into appropriate sizes, low type or full size partitions 19.2 (l) are used depending on the purpose of partitioning.The partitions 19.20 are air vents corresponding to the partition positions. Mouth 14
erected on top of. Thereby, the air outlet duct 15 and the ventilation passage inside the partition 19.20 are communicated with each other.

Therefore, in addition to direct blowing of the conditioned air from the floor 11,
Air outlet 1 opened in partition 19.20
9b, 19c.

The air is blown into the chamber R from any part or all of 20b, 20b2. In this case, partition 1
Air outlets that do not communicate with 9.20 may be covered with blind covers 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, which are used as void conditioned air ducts, and air conditioning equipment is installed using the free access floor. Compared to the air conditioning system that constitutes the system, it is possible to shorten the construction period, improve the workability such as making the 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 legal void, and the intake of indoor air is set in the void on the ceiling side, so when partitioning a room, it is necessary to install ventilation channels, outlets, etc. in partitions of appropriate size. By forming an air conditioner and erecting it in communication with the air outlet, it is possible to use the partition to perform air conditioning that corresponds to a free partition, and to perform air conditioning according to the situation from a position such as an appropriate height. .
