Description

The present invention relates to an air conditioning building.

For example, there are various air-conditioning methods in factories, such as spot air-conditioning in which cold air (air-conditioned air) is directly applied to workers and equipment, and zone air-conditioning for large spaces. Among them, zone air conditioning is effective when workers are assigned to the entire factory or when the work position is not constant. In this zone air conditioning, there is a problem that the air conditioning area becomes too wide when there is no partition in the space, the space other than the work area is also air-conditioned, and the amount of air conditioning energy used increases.

In order to solve this problem, it is conceivable to provide partitions for each of multiple air-conditioning zones and air-condition only the air-conditioning zones that correspond to the work area. However, if the space inside the factory is divided by partitions, cranes, etc. will be used inside the factory. It is not preferable because it becomes difficult to travel freely and new problems such as connecting a plurality of work areas with a conveyor or the like and making it impossible to continuously convey the product occur.

Here, a zone air conditioner that can realize comfortable air conditioning and can achieve miniaturization and energy saving has been proposed. Specifically, the main unit equipped with a heat exchanger for air supply that exchanges heat by allowing the return air from the air-conditioned zone to be freely cooled and heated, and the return air that has passed through the heat exchanger for air supply to the air-conditioned zone. It has two outlet units with an outlet provided on the front surface (see, for example, Patent Document 1).

JP-A-2009-103409

Even if the zone air conditioner described in Patent Document 1 is applied to a factory or the like, is it possible to air-condition a plurality of air-conditioning zones while reducing the amount of air-conditioning energy used as much as possible without partitioning the internal space of the factory or the like? I'm not sure if it isn't.

The present invention has been made in view of the above problems, and it is possible to perform zone air conditioning in a plurality of work areas while reducing the amount of air conditioning energy used as much as possible without partitioning the internal space of a factory or the like. The purpose is to provide an air-conditioned building.

In order to achieve the above object, one aspect of the air conditioning building according to the present invention is
An air-conditioned building that has at least a floor and a roof and has two or more air-conditioned zones inside.
For each air-conditioning zone, a ceiling material is arranged above the air-conditioning zone and below the roof.
An air conditioner that provides conditioned air is attached to the ceiling material in the conditioned zone.
It is characterized in that two or more of the air conditioning zones are continuous without being partitioned.

According to this aspect, below the roof, for example, a ceiling material extending in the horizontal direction is arranged for each air conditioner zone independently of the roof, and an air conditioner (indoor unit) unique to each ceiling material is attached. Therefore, zone air conditioning can be performed by the air conditioner while blocking the radiated heat from the roof with the ceiling material. Therefore, in a continuous space where two or more air-conditioning zones are not partitioned, each work area can be zone-air-conditioned while reducing the amount of air-conditioning energy used as much as possible. Here, the ceiling material of each air-conditioning zone is attached by hanging from the roof or by projecting from the wall of the building. Further, the ceiling materials of each air-conditioning zone are arranged at intervals from each other, for example, to prevent the heat of the ceiling material of any air-conditioning zone from being transferred to the ceiling material of another air-conditioning zone. it can. In the air-conditioning building of this embodiment, since each air-conditioning zone is provided with a unique ceiling material, a unique air conditioner can be attached to the ceiling material.

Further, since each air conditioning zone is provided with a unique ceiling material, the installation level of the ceiling material can be adjusted for each air conditioning zone. For example, by arranging the ceiling material at a low position, the air conditioning space in the air conditioning zone below the ceiling material can be narrowed as much as possible, which makes it possible to quickly perform air conditioning in the air conditioning zone. Alternatively, the power of the air conditioner can be reduced. In addition, since two or more air-conditioning zones inside the factory are continuous without being separated by walls or partitions, forklifts, cranes, self-propelled robots, etc. can freely run inside the factory. Products can be continuously transported by connecting the work areas (air conditioning zones) of the above with a conveyor or the like. That is, in the air-conditioning building of this embodiment, although the air-conditioning zone has a unique ceiling material, each air-conditioning zone has a structure in which the air-conditioning zone is not partitioned by a partition, so that the above-mentioned various effects can be obtained.

Further, in another aspect of the air conditioning building according to the present invention, the air conditioner is attached to the lower surface of the ceiling material, and an endless hanging wall is provided around the ceiling material.
The conditioned air flowing along the lower surface of the ceiling material is characterized in that the airflow direction is changed downward by the hanging wall.

According to this aspect, for example, conditioned air blown horizontally from an air conditioner attached to the lower surface of the ceiling material is blown horizontally along the lower surface of the ceiling material and then provided around the ceiling material. By allowing the conditioned air to flow downward through the endless hanging wall, the conditioned air can be returned in the conditioned zone, and effective conditioned air conditioning in the conditioned zone can be achieved. Here, the "endless hanging wall" means, for example, a rectangular frame-shaped or circular frame-shaped hanging wall along the contour of a ceiling material having a rectangular shape in a plan view or a ceiling material having a circular shape in a plan view. There is. For example, when conditioned air is flowed horizontally along the lower surface of the ceiling material extending in the horizontal direction, the Coanda effect forms an adhering flow of conditioned air along the lower surface of the ceiling material. Air-conditioned air can be effectively flowed. For example, when an air conditioner is installed at one corner of a rectangular shape in a plan view and air-conditioned air is blown out, the blown-out air-conditioned air flattens the lower surface of the ceiling material along a rectangular frame-shaped (endless) hanging wall. It can flow in an annular shape and spread over the entire lower surface of the ceiling material. In this way, the power of the air conditioner can be reduced by flowing the conditioned air by utilizing the Coanda effect.

The conditioned air whose airflow direction is changed downward by the hanging wall reaches the floor surface of the conditioned zone. The area of the ceiling material where the air conditioner is installed has a more negative pressure atmosphere than the other areas due to the blowout of air conditioning air. Therefore, the air conditioning air that reaches the floor surface flows through the floor surface and then air-conditioned. Change the air flow direction to the negative pressure area where the machine is located, and rise toward the negative pressure area of the ceiling material. In this way, a reflux of conditioned air in the conditioned zone is generated.

Another aspect of the air conditioner building according to the present invention is characterized in that an outdoor unit that fluidly communicates with the air conditioner is arranged in a ceiling space sandwiched between the ceiling material and the roof.

According to this aspect, since the outdoor unit that fluidly communicates with the air conditioner is arranged in the ceiling space sandwiched between the ceiling material and the roof, the length of the refrigerant pipe or the like connecting the air conditioner and the outdoor unit can be made possible. It can be shortened to the above, and it is not necessary to devise a piping route such as a refrigerant pipe. If the outdoor unit is literally installed outside the building, the length of the refrigerant pipe connecting the air conditioner and the outdoor unit will naturally increase. Further, when the length of the refrigerant pipe becomes long, it is necessary to devise to arrange the refrigerant pipe in a path that does not hinder the traveling inside the factory or the like where the crane or the like travels. In this embodiment, these problems can be solved and the material cost of the refrigerant pipe can be reduced. For example, in the form in which the air conditioner is attached to one end of the lower surface of the ceiling material, the outdoor unit can be installed at a position corresponding to the air conditioner on the upper surface of the ceiling material, and both can be connected by a refrigerant pipe.

Further, another aspect of the air-conditioning building according to the present invention is characterized in that the roof is provided with a ventilation fan communicating with the outside.

According to this aspect, for example, by providing a ventilation fan such as a roof fan that communicates with the outside on the roof, the high temperature air exhausted from the outdoor unit arranged in the ceiling space is effectively exhausted to the outside. can do. In addition, a ventilation fan may be installed at a position above the wall of the building (a position corresponding to the ceiling space). Here, it is preferable that the outdoor unit is provided with a wind direction plate in front of the outdoor unit to promote the flow of high-temperature air toward the ventilation fan.

Further, in another aspect of the air-conditioning building according to the present invention, the upper surface of the ceiling material has high reflectance.
The lower surface of the ceiling material is characterized by having a high emissivity.

According to this aspect, since the upper surface of the ceiling material has high reflectance, the radiant heat radiated from the roof can be reflected on the upper surface of the ceiling material, and the temperature rise of the ceiling material can be suppressed. Further, since the lower surface of the ceiling material has a high emissivity, for example, the lower surface of the ceiling material is cooled by the conditioned air blown from the air conditioner attached to the lower surface of the ceiling material, and the cooling heat of the lower surface is cooled. It can be radiated to the air conditioning zone below the ceiling material. Here, "high reflectance" means not only a material having a reflectance of 80% or more at a wavelength level of 300 nm to 400 nm or more, such as aluminum or silver, but also a material having a reflectance of 50% or more at a similar wavelength level. It also contains iron and the like. On the other hand, "high emissivity" means that the reflectance is lower (emissivity corresponding to) than the upper surface of high reflectance. For example, when aluminum is applied to the upper surface of the ceiling material, Examples thereof include copper and iron, which are materials having a higher emissivity (low reflectance) than this.

Further, in another aspect of the air-conditioning building according to the present invention, the ceiling material has a heat insulating material as a core material, a high reflectance layer is formed on the upper surface of the core material, and a high emissivity is formed on the lower surface of the core material. It is characterized in that a layer is formed.

According to this aspect, the ceiling material has a heat insulating material as a core material, has a high reflectance layer on the upper surface thereof, and has a high emissivity layer on the lower surface thereof, thereby changing from a roof to a high reflectance layer. The radiant heat can be blocked by a heat insulating material, and the transfer of heat to the layer having a high emissivity can be suppressed.

Further, in another aspect of the air conditioning building according to the present invention, the air conditioner and the outdoor unit that fluidly communicates with the air conditioner are attached to the upper surface of the ceiling material.
Below the floor, there is a distribution space through which conditioned air flows, and a plurality of conditioned air outlet holes are provided on the floor.
A duct connects the air conditioner and the distribution space.
The ceiling material is characterized in that an exhaust hole is provided in which the conditioned air rising in the air conditioning zone is exhausted into the ceiling space sandwiched between the ceiling material and the roof.

According to this aspect, the air conditioner and the outdoor unit are arranged on the upper surface of the ceiling material so that the air conditioner and the outdoor unit communicate with each other, and the air conditioning air is sent to the distribution space below the floor through a duct, and the air conditioning on the floor is air-conditioned from the outlet hole of the floor. By providing conditioned air to the zone, it is possible to air-condition the conditioned zone with an air conditioner while blocking the radiated heat from the roof with a ceiling material. Here, the floor can be formed by a double floor having a distribution space, a work floor stand installed on the floor of a building and having a distribution space, or the like. The conditioned air that has been heated in the process of rising in the conditioned zone is sent to the ceiling space through the exhaust holes of the ceiling material, and is exhausted to the outside through the roof.

As can be understood from the above description, according to the air-conditioning building of the present invention, a plurality of air-conditioning zones are zone-air-conditioned while reducing the amount of air-conditioning energy used as much as possible without partitioning the internal space of a factory or the like. be able to.

It is a vertical sectional view which shows an example of the air-conditioning building which concerns on 1st Embodiment. Both (a) and (b) are vertical sectional views showing an example of a ceiling material. FIG. 1 is a view taken along the line III in FIG. 1, showing an example of the flow of conditioned air on the lower surface of the ceiling material. It is a vertical sectional view which shows an example of the air-conditioning building which concerns on 2nd Embodiment.

Hereinafter, an example of the air-conditioning building according to each embodiment will be described with reference to the attached drawings. In the present specification and the drawings, substantially the same components may be designated by the same reference numerals to omit duplicate explanations.

[Air conditioning building according to the first embodiment]
First, the air-conditioning building according to the first embodiment will be described with reference to FIGS. 1 to 3. Here, FIG. 1 is a vertical sectional view showing an example of the air-conditioning building according to the first embodiment, and FIGS. 2 (a) and 2 (b) are vertical sectional views showing an example of a ceiling material. .. Further, FIG. 3 is a view taken along the line III in FIG. 1 and is a diagram showing an example of the flow of conditioned air on the lower surface of the ceiling material.

The air-conditioning building 100 is formed by a building 10 having a floor 17 supported by a foundation 19, a wall 14, and a roof 11, and having two or more air-conditioning zones Z1 and Z2 inside. The air-conditioning building 100 is applied to factories, distribution warehouses, etc. that manufacture various products and parts, and two or more air-conditioning zones Z1 and Z2 each form a work area, and each work area is zone-air-conditioned. Is. Although only two air-conditioning zones Z1 and Z2 are shown in the building 10 of the illustrated example, the building 10 may have three or more air-conditioning zones.

Each air conditioning zone Z1 and Z2 has its own ceiling material 20 above them and below the roof 11. The ceiling material 20 is a suspended ceiling suspended from the roof 11 via a hanging material 28. In the illustrated example, the installation level of the ceiling material 20 of each of the air conditioning zones Z1 and Z2 is the same level, but the installation level of the ceiling material 20 may be different for each of the air conditioning zones Z1 and Z2, or both ceiling materials. The installation level of 20 may be set as low as possible within a range that does not interfere with the work. By narrowing the air-conditioning space of the air-conditioning zones Z1 and Z2 below the ceiling material 20 as much as possible, it becomes possible to quickly air-condition the air-conditioning zones Z1 and Z2, which leads to a reduction in the power of the air conditioner 20. .. It should be noted that the end portion of the ceiling material may be supported by a wall and may project horizontally from the wall to the inside of the building (cantilever structure).

The air conditioning zones Z1 and Z2 form a continuous space without being separated from each other by a wall, a partition, or the like.

A ceiling space R is formed between the ceiling material 20 and the roof 11, and a plurality of hanging materials 28 hanging from the ceiling material 20 vertically penetrate the ceiling space R.

The roof 11 is formed of a metal roof made of steel plate, stainless steel, gallibarium steel plate, corrugated plate or folded plate obtained by coating or plating these plate materials with synthetic resin. The roof 11 may have a heat insulating material such as glass wool or foamed polyolefin foam inside the steel plate or the like, and further has a low emissivity aluminum plate or the like inside the steel plate or the like or inside the heat insulating material. May be. By having a heat insulating material inside the steel plate or the like constituting the roof, the solar heat of the steel plate or the like can be blocked by the heat insulating material. Further, by providing an aluminum plate or the like having a low emissivity inside the steel plate or the like constituting the roof, it is possible to suppress the radiation of solar heat to the inside of the building 10.

A roof fan 12 (an example of a ventilation fan) is attached to a central position of the roof 11 (in the illustrated example, a position separating the air conditioning zones Z1 and Z2). For example, when other air-conditioning zones are provided at intervals from the air-conditioning zones Z1 and Z2 shown in the paper depth direction of FIG. 1, a separate roof fan corresponding to these other air-conditioning zones is further provided on the roof 11. It may be attached. In addition to the roof fan 12 in the illustrated example, the ventilation fan applied to the air-conditioning building 100 includes a propeller fan, a sirocco fan, a turbo fan, and a mixed flow fan, which are attached to a position above the wall 14 (ceiling space R, etc.). , Line flow fan, etc. may be used.

The wall 6 has a structure in which a metal exterior material and an interior material are joined by a base material made of a shaped steel material such as channel steel, and is erected on a cloth foundation 9 made of reinforced concrete. Further, the floor 17 is formed of, for example, a soil concrete slab made of reinforced concrete.

An air conditioner 40 is attached to the lower surface of the ceiling material 20. More specifically, as shown in FIG. 3, an air conditioner 40 that blows out conditioned air in the horizontal direction is fixed in the vicinity of one corner of the ceiling member 20 having a rectangular plan view.

On the other hand, the outdoor unit 50 is attached to the ceiling space R on the upper surface of the ceiling material 20. Here, the outdoor unit is literally a device that is installed outside the building to exhaust hot air, but in the air conditioner building 100, it is assumed that it is installed indoors in the building 10.

An air conditioner 40 is attached to the lower surface of the ceiling material 20, for example, an outdoor unit 50 is attached to a position corresponding to the air conditioner 40 on the upper surface of the ceiling material 20, and a through hole 20a provided in the ceiling material 20 is attached. A refrigerant pipe 58 penetrating through the air conditioner 40 communicates fluidly with the air conditioner 40 and the outdoor unit 50.

When the outdoor unit is installed outdoors like a normal outdoor unit, the length of the refrigerant pipe connecting the air conditioner and the outdoor unit tends to be long, but as is clear from FIG. 1, the ceiling material 20 is used. Since the air conditioner 40 and the outdoor unit 50 are arranged at close positions with each other sandwiched between them, the length of the refrigerant pipe 58 connecting the two can be shortened as much as possible.

A wind direction plate 55 oriented to the roof fan 12 is attached to the front surface (exhaust surface) of the outdoor unit 50.

As shown in FIG. 2A, the ceiling material 20 is formed of a core material 21, a high reflectance layer 22 on the upper surface of the core material 21, and a high emissivity layer 23 on the lower surface of the core material 21. To. The core material 21 is made of a heat insulating material, and is formed of, for example, a foam material such as expanded polystyrene, expanded styrene, expanded polyolefin, polystyrene, and styrene. Further, an aluminum plate, an aluminum film, or the like is applied to the high reflectance layer 22, and this can be adhered to the core material 21 or the like. Further, an iron plate, a copper plate, a copper film or the like is applied to the high emissivity layer 23, and this can be adhered to the core material 21 or the like.

On the other hand, FIG. 2B shows another example of the ceiling material 20A. The ceiling material 20A has, for example, a grid-shaped frame 24 as a core material, and a high reflectance layer 22 and a high emissivity layer 23 are attached above and below the frame frame 24. In the ceiling material 20A, the gap G inside the frame 24 sandwiched between the upper and lower high reflectance layers 22 and the high emissivity layers 23 forms a heat insulating layer.

In the air conditioner building 100, below the roof 11, for example, a ceiling material 20 extending in the horizontal direction is arranged in each of the air conditioner zones Z1 and Z2 independently of the roof 11, and the air conditioner 40 unique to each ceiling material 20 is provided. The air conditioner 40 can perform zone air conditioning while blocking the radiated heat from the roof 11 with the ceiling material 20.

Further, since the ceiling materials 20 and 20A have the high reflectance layer 22 on the upper surface thereof, the radiant heat radiated from the roof 11 is transferred to the high reflectance layer 22 on the upper surface of the ceiling materials 20 and 20A in the Y1 direction. It can be reflected and the temperature rise of the ceiling materials 20 and 20A can be suppressed.

Further, the ceiling materials 20 and 20A have a core material 21 made of a heat insulating material and a core material 24 having a gap G forming a heat insulating layer between the high reflectance layer 22 and the high emissivity layer 23, whereby the roof is provided. The radiant heat radiated from 11 to the high reflectance layer 22 can be blocked by the core materials 21 and 24, and the transfer of heat to the high emissivity layer 23 can be suppressed.

Further, since the ceiling material 20 has a high emissivity layer 23 on the lower surface thereof, the conditioned air blown out from the air conditioner 40 attached to the lower surface of the ceiling materials 20 and 20A causes the ceiling materials 20 and 20A to be conditioned. The lower surface is cooled, and the cold heat of the lower surface can be radiated in the Y2 direction to the air conditioning zones Z1 and Z2 below the ceiling materials 20 and 20A.

In this way, the ceiling materials 20 and 20A having the high emissivity layer 22 and the high emissivity layer 23 are arranged on the ceilings of the air conditioning zones Z1 and Z2, and the outdoor units 50 are placed above and below the ceiling materials 20 and 20A. With the configuration in which the air conditioner 40 is attached, it is possible to effectively zone air-condition each work area while reducing the amount of air-conditioning energy used as much as possible in a continuous space where two or more air-conditioning zones Z1 and Z2 are not partitioned. it can. Further, since each air conditioning zone Z1 and Z2 are continuous without being partitioned, a forklift, a crane, a self-propelled robot, etc. can freely travel inside a factory or the like, and a plurality of work areas (air conditioning zone Z1) can be freely traveled. , Z2) can be connected by a conveyor or the like to continuously convey the product.

Returning to FIG. 1, an endless hanging wall 30 is provided around the lower surface of the ceiling material 20. As shown in FIG. 3, the plan view shape of the ceiling material 20 is rectangular, and the hanging wall 30 also has a rectangular frame-like alignment similar to the outer contour of the ceiling material 20. The air conditioner 40 is arranged inside the endless hanging wall 30.

As shown in FIG. 1, when the conditioned air is flowed from the air conditioner 40 along the lower surface of the ceiling material 20 in the horizontal X1 direction, an adhering flow of the conditioned air along the lower surface of the ceiling material 20 is formed due to the Coanda effect. To. As shown in FIG. 3, when the conditioned air is blown out from the air conditioner 40 at one corner of the ceiling material 20 having a rectangular view in a plan view in the horizontal X1 direction, the conditioned air blown out has a rectangular frame shape. The lower surface of the ceiling material 20 can flow in an annular shape in a plan view along the hanging wall 30 and spread over the entire lower surface of the ceiling material 20.

Further, as shown in FIG. 1, a part of the conditioned air flowing in the X1 direction while forming an adhering flow on the lower surface of the ceiling material 20 is partially changed in the downward X2 direction by the hanging wall 30, and the conditioned air zone. It flows down Z1 and Z2 in the X3 direction and reaches the floor surface.

By the way, in the ceiling material 20, the region where the air conditioner 40 is attached forms a negative pressure region N more than other regions due to the blowing of conditioned air. Therefore, the air-conditioned air that has reached the floor surface is changed in the airflow direction to the X4 direction on the side with the negative pressure region N, flows in the floor surface in the horizontal direction X5 direction, and then changes the airflow direction to the X6 direction. , Ascends in the air conditioning zones Z1 and Z2 in the X7 direction and flows toward the negative pressure region N near the ceiling material 20.

In this way, three-dimensional recirculation such as the recirculation of the conditioned air on the lower surface of the ceiling material 20 shown in FIG. 3 and the recirculation of the conditioned air in the air conditioning zones Z1 and Z2 shown in FIG. 1 is generated, and the air conditioning zones Z1 and Z2 are formed. Air conditioning can be effectively performed with air conditioning air.

In order to utilize the coanda effect, air conditioning is performed by allowing air conditioning air to flow horizontally from the air conditioner 40 along the lower surface of the ceiling material 20, and by appropriately changing the air conditioning air flow direction by the endless hanging wall 30. Air conditioning in air conditioning zones Z1 and Z2 can be performed while reducing the power of the machine.

The hanging wall 30 not only hangs vertically downward from the ceiling material 20 extending in the horizontal direction as shown in the illustrated example, but also hangs inwardly in the air conditioning zones Z1 and Z2, and the air conditioning zone Z1. There is also a mode in which the Z2 hangs in an inclined manner to the outside, and these various modes can realize a desired change in the air flow direction.

After the heated air that has been heated in the process of recirculating the air conditioning zones Z1 and Z2 flows into the air conditioner 40, it is sent to the outdoor unit 50 via the refrigerant pipe 58, and is sent to the outdoor unit 50 via the wind direction plate 55 on the front surface of the outdoor unit 50. The air is exhausted in the X8 direction toward the roof fan 12. The roof fan 12 has an exhaust port 12a leading to the outdoors, and by operating the roof fan 12, the heated air exhausted from the outdoor unit 50 is taken in by the roof fan 12 and outdoors through the exhaust port 12a. It is exhausted in the X9 direction.

[Air conditioning building according to the second embodiment]
Next, the air-conditioning building according to the second embodiment will be described with reference to FIG. Here, FIG. 4 is a vertical cross-sectional view showing an example of the air conditioning building according to the second embodiment.

In the air-conditioning building 200, ceiling materials 20A having a plurality of exhaust holes 26 are arranged on the ceilings of the air-conditioning zones Z1 and Z2. The ceiling material 20A shown in the figure includes a hanging wall 30 similar to the ceiling material 20 of the air-conditioned building 100, but in the present embodiment, the hanging wall 30 does not change the airflow direction of the conditioned air. Is not always necessary.

Further, the duct air conditioner 40A is arranged on the upper surface of the ceiling material 20A in the ceiling space R, and similarly, the outdoor unit 50 is arranged on the upper surface of the ceiling material 20A, and both are fluid-communicated by the refrigerant pipe 58. ..

The floor is a double floor formed by a soil concrete slab 17 and an upper floor material 18 arranged via a distribution space U above the slab 17. A contact port 18a is opened at the end of the upper floor material 18, and a plurality of blowout holes 18b are opened at positions corresponding to the air conditioning zones Z1 and Z2 of the upper floor material 18.

One end of the duct 59 is attached to the duct air conditioner 40A, the duct 59 extends in the vertical direction along the wall 14, and the other end of the duct 59 is connected to the communication port 18a of the upper floor material 18.

According to the configuration shown in FIG. 4, the conditioned air blown out from the duct air conditioner 40A in the X10 direction flows into the distribution space U from the communication port 18a in the X11 direction through the duct 59, and passes through the distribution space U in the process of passing through the upper floor. It rises in the X12 direction through the plurality of blowout holes 18b of the material 18 and is provided to the air conditioning zones Z1 and Z2.

A negative pressure region N is formed in the vicinity of the duct air conditioner 40A above the ceiling material 20A, and the temperature-increasing air generated by the temperature rise of the conditioned air in the process of rising the air-conditioning zones Z1 and Z2 is the ceiling material. It flows into the ceiling space R in the X13 direction through the plurality of exhaust holes 26 included in the 20A. The heated air flowing into the ceiling space R is taken into the operating roof fan 12 and exhausted to the outside in the X9 direction through the exhaust port 12a. At the same time, the heated air exhausted from the outdoor unit 50 is also taken in by the roof fan 12 and exhausted to the outside in the X9 direction through the exhaust port 12a.

The ceiling material 20A also has the structure shown in FIG. 2A or FIG. 2B, similarly to the ceiling material 20. Also in the air conditioner building 200, below the roof 11, for example, ceiling materials 20A extending in the horizontal direction are arranged in each of the air conditioner zones Z1 and Z2 independently of the roof 11, and an air conditioner unique to each ceiling material 20A. Since 40A is attached, zone air conditioning can be performed by the air conditioner 40A while blocking the radiated heat from the roof 11 by the ceiling material 20A. Further, since each air conditioning zone Z1 and Z2 are continuous without being partitioned, a forklift, a crane, a self-propelled robot, etc. can freely travel inside a factory or the like, and a plurality of work areas (air conditioning zone Z1). , Z2) can be connected by a conveyor or the like to continuously convey the product.
