Description

According to the present invention, in a building having a horizontal ventilation space on a plurality of floors through which outside air can be ventilated in the horizontal direction through a plurality of open portions open to the outside, the horizontal ventilation space on each floor is aligned with the horizontal direction in the horizontal ventilation space. It relates to a ventilation system equipped with an auxiliary ventilation means capable of assisting horizontal ventilation.

Ventilation of a horizontal ventilation space where outside air can be ventilated in the horizontal direction through multiple open portions open to the outside is basically performed by the natural wind flowing in and out through the open portions, but the natural wind is weak and ventilated. When a shortage occurs, an auxiliary ventilation means such as a blower arranged in the horizontal ventilation space may be operated to assist the horizontal ventilation in the horizontal ventilation space and secure the required ventilation volume (for example, Patent Document 1 and See 2.).

In this way, the ventilation system that ventilates the horizontal ventilation space by blowing natural wind and auxiliary ventilation means can also be applied to the ventilation of the horizontal ventilation space provided on each floor of the building. As such a building having horizontal ventilation spaces on a plurality of floors, for example, there is a logistics facility having a central lane as a horizontal ventilation space in which vehicles enter and exit each of the plurality of floors having a warehouse space for storing luggage. That is, in this distribution facility, since the central lane of each floor is open to the outside through the vehicle entrance / exit, the ventilation of the central lane of each floor is such that the outside air is horizontally connected to the central lane through the vehicle entrance / exit. This is done by ventilating, and an auxiliary blower can be placed in this central lane to assist horizontal ventilation in the central lane.

When ventilation of the horizontal ventilation space on each floor is performed by using natural wind in a building with horizontal ventilation space on multiple floors, strong natural wind can be expected on the upper floors, but the natural wind is generally weak on the lower floors. Therefore, there is a concern that the air environment may deteriorate due to insufficient ventilation, such as the retention of exhaust gas from vehicles passing through the central lane as a horizontal ventilation space and the rise in air temperature due to the heat of the exhaust gas. Therefore, on the lower floors, in order to eliminate such a lack of ventilation, it is necessary to operate the auxiliary ventilation means with a relatively high load, which causes a problem that power consumption increases and operating costs increase. ..

In view of this situation, the main subject of the present invention is the air in the horizontal ventilation space on each floor in the ventilation system for ventilating the horizontal ventilation space provided on each floor of the building by using the natural wind and the ventilation by the auxiliary ventilation means. The point is to provide technology that can improve energy saving and reduce operating costs while maintaining a comfortable environment.

The first characteristic configuration of the present invention is a building having a plurality of open portions open to the outside and having horizontal ventilation spaces on a plurality of floors through which the outside air can be ventilated in the horizontal direction.
A ventilation system equipped with an auxiliary ventilation means capable of assisting horizontal ventilation along the horizontal direction in the horizontal ventilation space on each floor.
It is erected over the horizontal ventilation space on multiple floors, and has a vertical ventilation section with an opening that opens into the horizontal ventilation space on multiple floors .
The upper end opening of the vertical ventilation portion is provided as an opening that opens into the horizontal ventilation space on the upper floor .

According to this configuration, in a building in which the horizontal ventilation space in which the auxiliary ventilation means is arranged is provided on a plurality of floors, a vertical ventilation section for connecting the horizontal ventilation spaces on the upper and lower floors is provided. Due to the pressure difference, a part of the air in the horizontal ventilation space on the lower floor can be raised and discharged through the vertical ventilation section.
Specifically, since the horizontal ventilation due to the natural wind in the horizontal ventilation space of the lower floor is generally weaker than that of the upper floor, the air temperature of the horizontal ventilation space of the lower floor tends to be higher than that of the upper floor. Therefore, in the vertical ventilation section connecting the horizontal ventilation spaces on the upper and lower floors, there is a temperature difference such that the air temperature on the lower floor side is higher than that on the upper floor side, and this temperature difference causes the so-called chimney effect. An updraft called will occur.
Further, in the vicinity of the upper end opening of the vertical ventilation portion, generally strong horizontal ventilation can be expected. Therefore, if the air in the vertical ventilation portion is attracted to the outside from the upper end opening by using the power of the horizontal ventilation, the pressure in the vertical ventilation portion near the upper end opening becomes smaller than that on the lower side. A difference is generated, and this pressure difference causes an upward flow.
When an ascending current is generated in the vertical ventilation section connecting the horizontal ventilation spaces on the upper and lower floors in this way, a part of the air in the horizontal ventilation space on the lower floors is raised to the upper floor side through the vertical ventilation section and discharged. can do.

As a result, in the horizontal ventilation space on the lower floors, even if the ventilation power of the auxiliary ventilation means to supplement the horizontal ventilation is reduced, the ventilation is strengthened and the deterioration of the air environment due to insufficient ventilation with respect to the required ventilation volume is eliminated. can do.
Therefore, according to the present invention, it is possible to improve energy saving and reduce operating costs while maintaining a comfortable air environment in the horizontal ventilation space on each floor.

Further, according to this configuration, the upper end opening of the vertical ventilation portion does not open directly to the outside but opens into the horizontal ventilation space of the upper floor, so that the horizontal ventilation space of the lower floor By raising a part of the air to the upper floor side through the vertical ventilation section and introducing it into the horizontal ventilation space of the upper floor, it can be discharged to the outside together with the horizontal ventilation of the horizontal ventilation space. In addition, in the horizontal ventilation space on the upper floors equipped with auxiliary ventilation means, relatively strong horizontal ventilation can be stably obtained. Therefore, the power of the horizontal ventilation is used to ventilate the air in the vertical ventilation section at the upper end. Can be stably and sufficiently attracted from. Therefore, the air in the vertical ventilation portion can be suitably discharged to the outside together with the horizontal ventilation in the horizontal ventilation space.
The second characteristic configuration of the present invention is a building having a plurality of open portions open to the outside and having horizontal ventilation spaces on a plurality of floors through which the outside air can be ventilated in the horizontal direction.
A ventilation system equipped with an auxiliary ventilation means capable of assisting horizontal ventilation along the horizontal direction in the horizontal ventilation space on each floor.
It is erected over the horizontal ventilation space on multiple floors, and has a vertical ventilation section with an opening that opens into the horizontal ventilation space on multiple floors.
The opening on each floor of the vertical ventilation portion is open in a direction substantially orthogonal to the direction of horizontal ventilation in the horizontal ventilation space.
The third characteristic configuration of the present invention is a building having a plurality of open portions open to the outside and having horizontal ventilation spaces on a plurality of floors through which the outside air can be ventilated in the horizontal direction.
A ventilation system equipped with an auxiliary ventilation means capable of assisting horizontal ventilation along the horizontal direction in the horizontal ventilation space on each floor.
It is erected over the horizontal ventilation space on multiple floors, and has a vertical ventilation section with an opening that opens into the horizontal ventilation space on multiple floors.
The vertical ventilation portion causes an upward flow inside due to a temperature difference or a pressure difference between the upper floor side and the lower floor side, and a part of the air in the horizontal ventilation space on the lower floor is taken into the inside through the opening. The point is that the taken-in internal air is discharged from the opening to the horizontal ventilation space on the upper floors.
The fourth characteristic configuration of the present invention is a building having a plurality of open portions open to the outside and having horizontal ventilation spaces on a plurality of floors through which the outside air can be ventilated in the horizontal direction.
A ventilation system equipped with an auxiliary ventilation means capable of assisting horizontal ventilation along the horizontal direction in the horizontal ventilation space on each floor.
It is erected over the horizontal ventilation space on multiple floors, and has a vertical ventilation section with an opening that opens into the horizontal ventilation space on multiple floors.
The vertical ventilation portion has an opening that opens to the lower side of the horizontal ventilation space on each floor on the lower floor side and an opening that opens to the upper side of the horizontal ventilation space on the uppermost floor.

The fifth characteristic configuration of the present invention is that the vertical ventilation portions are dispersedly arranged at a plurality of locations in the horizontal direction in the horizontal ventilation space.

According to this configuration, a part of the air in the horizontal ventilation space on the lower floors is exhausted through the vertical ventilation parts distributed at multiple locations, so that the ventilation shortage for the required ventilation volume is reduced in every corner of the horizontal ventilation space. It can be resolved.

In the sixth characteristic configuration of the present invention, the auxiliary blowing means is configured so that the blowing state can be adjusted.
The point is that the ventilation control means for controlling the ventilation state of the auxiliary ventilation means is provided according to the natural ventilation state of the horizontal ventilation due to the natural wind in the horizontal ventilation space.

According to this configuration, horizontal ventilation is controlled by controlling the ventilation state such as the ventilation direction and the amount of ventilation of the auxiliary ventilation means according to the natural ventilation state such as the direction and strength of the horizontal ventilation due to the natural wind in the horizontal ventilation space. It is possible to appropriately assist horizontal ventilation in the space, and it is possible to realize appropriate horizontal ventilation using natural wind and ventilation by auxiliary ventilation means.

This onset Ming, openings of each floor which the vertical ventilation part has found it is preferable to have an opening in a direction substantially orthogonal to the direction of the horizontal ventilation of the horizontal ventilation space.

According to this configuration, the openings on each floor provided in the vertical ventilation section are opened in a posture substantially orthogonal to the horizontal ventilation direction of the horizontal ventilation space, so that an attractive force is applied from the inside of the vertical ventilation section toward the horizontal ventilation space. Can be caused. In general, the closer to the upper floors, the greater the flow velocity of horizontal ventilation due to natural wind, and therefore, the closer to the upper floors, the greater the attractive force applied to the openings of the vertical ventilation portions on each floor. As a result, in the vertical ventilation section, a pressure gradient that becomes smaller as it goes upward is generated, and the air can be appropriately raised, and the air from the horizontal ventilation space on the lower floor to the horizontal ventilation space on the upper floor can be raised. Can be introduced more efficiently. Further, when the direction of horizontal ventilation in the horizontal ventilation space is reversed, the opening direction of the opening in the vertical ventilation portion can be made substantially orthogonal to the direction of one horizontal ventilation. Can be made substantially orthogonal to the other horizontal ventilation direction that is inverted. Therefore, it is possible to generate an attractive force according to the flow velocity of the horizontal ventilation at the opening of each floor by utilizing both horizontal ventilations that are reversed.

An embodiment of the present invention will be described with reference to the drawings.
In the distribution facility 100 shown in FIGS. 1, 2 and 3, the central lane in which the vehicle T such as a truck passes adjacent to the warehouse space W on each of the plurality of floors F having the warehouse space W for storing luggage. It is configured as a building having R, and the ventilation system of the present embodiment is constructed for ventilation of the central lane R in the distribution facility 100. In the present embodiment, the distribution facility 100 is provided with central lanes R1, R2, R3, and R4 having a plurality of open portions O1 to O4 on each of the four floors F1, F2, F3, and F4. It will be a building.

As shown in FIGS. 1 and 2, the central lane R on each floor F is configured as a straight lane with vehicle entrances and exits 10 leading to the rampway L at both ends, and warehouses on both sides thereof. Space W is provided. Further, on the central lane R side of the warehouse space W, a truck berth B is provided in which the vehicle T can stop for loading and unloading luggage. In the present embodiment, the warehouse space W is configured to ventilate independently of the central lane R.

Each vehicle entrance / exit 10 that sandwiches the central lane R is appropriately provided with an automatic opening / closing shutter (not shown) that is opened when the vehicle enters / exits. The vehicle entrance / exit ports 10 provided at both ends of the central lane R function as a plurality of open portions O opened to the outside (an example of the outside), and the central lane R has these plurality of open portions O. It functions as a horizontal ventilation space where the outside air can be ventilated in the horizontal direction. That is, the central lane R is ventilated by allowing the outside air to ventilate in the horizontal direction through a plurality of open portions O opened to the outside, and the horizontal ventilation along the horizontal direction causes the wind to flow out through the open portions O. It is done by entering.

Further, as shown in FIGS. 2 and 3, the floor height of the uppermost floor F4 is higher than that of each floor F1 to F3 on the other lower floor side, and accordingly, the vehicle of the uppermost floor F4 enters. A gallery 11 for letting in and out the outside air is provided above the exit port 10. That is, on the uppermost floor F4, the garage 11 also functions as the opening portion O4 in addition to the vehicle entrance / exit 10 so that the opening area of the opening portion O4 on the uppermost floor F4 becomes the other lower floor side. It is larger than F1 to F3 on each floor. In general, the higher the altitude, the stronger the natural wind tends to be. Therefore, in the uppermost floor F4, the inflow and outflow of the natural wind through the open portion O4 is compared with the other floors F1 to F3 on the lower floor side. The amount increases, and the air volume and speed of horizontal ventilation due to natural wind in the central lane R4 tend to increase.

When the central lane R of each floor F is ventilated by using the natural wind in this way, the ventilation may be insufficient only by the natural wind. Therefore, the central lane R on each floor F is provided with an auxiliary ventilation means 2 capable of assisting horizontal ventilation along the horizontal direction in the central lane R.
Specifically, the auxiliary blower means 2 is composed of a first blower 2a and a second blower 2b alternately arranged along the extending direction of the central lane R.

As shown in FIGS. 1 and 2, the first blower 2a is directed from the opening portion O on one side to the opening portion O on the other side (for example, the direction from the right side to the left side in FIGS. 1 and 2. It is installed near the ceiling (upper side) of the central lane R to blow air in the "1 ventilation direction X1"), while the second blower 2b is in the direction opposite to that of the first blower 2a. (For example, in FIGS. 1 and 2, the direction from the left side to the right side; hereinafter referred to as "second ventilation direction X2") is installed near the ceiling (upper side) of the central lane R.

That is, the auxiliary blower means 2 has a first blower state in which only the first blower 2a is operated as shown in FIG. 4A and a second blower state in which only the second blower 2b is operated as shown in FIG. 4B. The blowing direction, which is the blowing state, can be reversed by switching between the blowing state and the blowing state. Further, the auxiliary blower means 2 adjusts the operating duty ratio of the blowers 2a and 2b to be operated intermittently, adjusts the number of operating blowers 2a and 2b, operates the blowers 2a and 2b in the operating state, and the like. By adjusting, the amount of air blown, which is the state of air blown, can be adjusted.

A control device (not shown) for controlling the operation of the ventilation system of the present embodiment is provided, and by executing a predetermined program, this control device causes horizontal ventilation due to natural wind in the central lane R. It functions as a ventilation control means 15 for controlling the ventilation state of the auxiliary ventilation means 2 according to the natural ventilation state. The details of the ventilation control by the ventilation control means 15 will be described below with reference to FIG. In FIG. 4, the description of the vertical duct 1 is omitted.

That is, as shown in FIG. 4A, when the direction of the natural wind measured by, for example, an anemometer (not shown) provided outdoors is along the first ventilation direction X1, the ventilation control is performed. The means 15 operates only the first blower 2a that blows air along the first ventilation direction X1. As a result, when horizontal ventilation in the first ventilation direction X1 is generated in the central lane R due to natural wind, the horizontal ventilation can be assisted by the ventilation of the first blower 2a.
On the other hand, as shown in FIG. 4B, when the direction of the natural wind is along the second ventilation direction X2, the ventilation control means 15 blows the air along the second ventilation direction X2. Only the blower 2b is operated. As a result, when the natural wind causes horizontal ventilation in the second ventilation direction X2 in the central lane R, the horizontal ventilation can be assisted by the ventilation of the second blower 2b.

Further, the blower control means 15 is an auxiliary blower means so that the wind speed of horizontal ventilation in the central lane R measured by, for example, an anemometer (not shown) provided in the central lane R is maintained at the target wind speed. The amount of air blown by 2 is controlled. As a result, the wind speed of the horizontal ventilation in the central lane R is maintained at the target wind speed for proper ventilation.

When the ventilation control by the ventilation control means 15 is executed in this way, for example, a floor closer to the uppermost floor F4 can be expected to have a stronger natural wind, so that the operation frequency and operation power of the auxiliary ventilation means 2 can be suppressed to a low level. However, for example, a floor closer to the lowest floor F1 cannot be expected to have a strong natural wind, so there is a concern that the air environment may deteriorate due to insufficient ventilation only by ventilation by the natural wind. Therefore, on the floor close to the lowest floor F1, the operating frequency and operating power of the auxiliary blowing means 2 become high, and as a result, there may be a problem that the operating cost increases.

Therefore, the ventilation system of the present embodiment has a characteristic configuration for improving energy saving and reducing operating costs while maintaining a comfortable air environment in the central lane R on each floor F. , The details of the feature configuration will be added below.
That is, as shown in FIGS. 2 and 3, the distribution facility 100 has openings 1a and 1b that are erected over the central lane R of the plurality of floors F and open to the central lane R of the plurality of floors F. A vertical duct 1 (an example of a vertical ventilation section) is provided. Specifically, this vertical duct 1 is composed of square ducts erected from the lowest floor F1 to the top floor F4 and extending in the vertical direction, and each floor on the lower floor side of the first to third floors. An opening 1a that opens near the floor surface (lower side) of the central lanes R1 to R3 in F1 to F3, and an opening that opens near the ceiling (upper side) of the central lane R4 in the uppermost floor F4 of the fourth floor. It has 1b and. As shown in FIG. 1, such vertical ducts 1 are dispersedly arranged at a plurality of locations in the extending direction (horizontal direction) of the central lane R on both sides of the central lane R.

Further, as shown in FIGS. 2 and 3, the openings 1a and 1b of each floor F of the vertical duct 1 always have the same horizontal ventilation direction even when the horizontal ventilation direction in the central lane R is reversed. It is opened in a direction substantially orthogonal to each other. Specifically, the opening 1a that opens in the central lanes R1 to R3 of each floor F1 to F3 on the lower floor side opens on the side surface of the side facing the center side of the central lane R (inside when viewed from the central lane R). However, the opening direction is formed in the vertical duct 1 so as to be orthogonal to the extending direction of the central lane R. On the other hand, the opening 1b that opens to the central lane R4 of the uppermost floor F4 is formed as the upper end opening of the vertical duct 1. That is, the opening 1b of the vertical duct 1 does not directly open to the outside, but opens to the central lane R4 of the uppermost floor F4.

By providing the vertical duct 1 as described above, due to the temperature difference and pressure difference of the air, a part of the air in the central lanes R1 to R3 in each floor F1 to F3 on the lower floor side passes through the opening 1a. It flows into the vertical duct 1 and rises. Then, the air that has risen in the vertical duct 1 is introduced into the central lane R4 of the uppermost floor F4 through the opening 1b, and then is discharged to the outside together with the horizontal ventilation of the central lane R4.

That is, as shown in FIGS. 2 and 3, the horizontal ventilation due to the natural wind in the central lanes R1 to R3 of each floor F1 to F3 on the lower floor side is generally weaker than that of the uppermost floor F4. The air temperature of the central lanes R1 to R3 on the side floors F1 to F3 tends to rise more than that on the uppermost floor F4. As a result, in the vertical duct 1 connecting the central lane R of each floor F, a temperature difference occurs such that the air temperature on each floor F1 to F3 on the lower floor side is higher than that on the uppermost floor F4 side. Therefore, this temperature difference causes an ascending current called the so-called chimney effect.
Further, even when such a temperature difference does not occur, the air in the vertical duct 1 can be evacuated by utilizing the relatively strong horizontal ventilation power stably obtained in the central lane R4 of the uppermost floor F4. If it is attracted to the outside from the opening 1b on the upper end side, a pressure difference occurs in the vertical duct 1 such that the pressure near the opening 1b on the upper end side becomes smaller than that on the lower side, and this pressure difference causes an upward flow. Will occur.

When an ascending flow is generated in the vertical duct 1 in this way, a part of the air in the central lane R in each floor F1 to F3 on the lower floor side flows into the vertical duct 1 through the opening 1a, and then the uppermost floor F4. It rises to the side, is introduced into the central lane R4 of the uppermost floor F4 through the opening 1b, and is discharged to the outside together with the horizontal ventilation of the central lane R4. As a result, in the central lanes R1 to R3 of each floor F1 to F3 on the lower floor side, exhaust is performed through the vertical duct 1 to strengthen the ventilation, so that the ventilation power of the auxiliary ventilation means 2 for supplementing the horizontal ventilation is enhanced. Even if the value is reduced, the deterioration of the air environment due to insufficient ventilation with respect to the required ventilation volume will be eliminated.

Further, as shown in FIGS. 1 and 2, since the vertical ducts 1 are dispersedly arranged at a plurality of locations on both sides of the central lane R, the central lanes R1 to R3 in each floor F1 to F3 on the lower floor side A part of the air is exhausted through the vertical ducts 1 distributed at these plurality of locations. As a result, the insufficient ventilation with respect to the required ventilation volume is eliminated in every corner of the central lanes R1 to R3.

In the central lane R4 of the uppermost floor F4, as shown in FIGS. 2 and 3, the opening 1b on the upper end side of the vertical duct 1 is directed upward so as to be substantially orthogonal to the horizontal ventilation direction of the central lane R4. Since it is open, the opening 1b on the upper end side has a relatively strong attractive force that attracts the air in the vertical duct 1 to the central lane R4 side by using the power of relatively strong horizontal ventilation. Occurs. As a result, the ascending flow in the vertical duct 1 is strengthened, and the air in the vertical duct 1 can be suitably discharged to the outside together with the horizontal ventilation of the central lane R4.
On the other hand, also in the central lanes R1 to R3 of each floor F1 to F3 on the lower floor side, the opening 1a of the vertical duct 1 is opened laterally substantially orthogonal to the horizontal ventilation direction of the central lane R4. Therefore, an attractive force using the power of horizontal ventilation is generated in the opening 1a.

In general, the closer to the uppermost floor F4, the greater the flow velocity of horizontal ventilation due to natural wind. Therefore, the attractive force applied to the openings 1a and 1b of the vertical duct 1 of each floor F is the uppermost floor F4. It becomes the largest in the opening 1b, and becomes smaller in the opening 1a provided below it as it approaches the lowest floor F1. That is, in the vertical duct 1, a pressure gradient that becomes smaller toward the upper side is generated, and the air is suitably raised by the pressure gradient.

Moreover, the opening 1b on the upper end side of the vertical duct 1 in the central lane R4 of the uppermost floor F4 is installed near the ceiling where the first blower 2a and the second blower 2b can easily receive the air. The opening 1a of the vertical duct 1 in the central lanes R1 to R3 of each floor F1 to F3 on the lower floor side is installed near the floor surface where it is difficult to directly receive the air blown by the first blower 2a and the second blower 2b. ing. As a result, the pressure gradient can be further strengthened in the vertical duct 1 and the ascending flow can be promoted.
In any of the openings 1a and 1b of the vertical duct 1, even if the direction of horizontal ventilation in the central lane R is reversed, the opening is always substantially orthogonal to the direction of horizontal ventilation. An attractive force using the power of horizontal ventilation can always be generated in 1a and 1b.

[Another Embodiment]
(1) In the above embodiment, the ventilation of the warehouse space W is configured to be independent of the ventilation by the horizontal ventilation of the central lane R, but these ventilations may be combined and configured.
For example, in the ventilation system constructed in the distribution facility 200 shown in FIG. 5, the air supply port 21 is provided on the wall portion of the warehouse space W opposite to the central lane R, while the truck berth of the warehouse space W. An exhaust port 23 is provided between B and the central lane R. Then, by operating the blower 22 provided in the warehouse space W, the outside air is taken into the warehouse space W through the air supply port 21, and the air that has passed through the warehouse space W is taken as exhaust, and is centered through the exhaust port 23. The warehouse space W is ventilated in the form of discharging to the lane R. Then, the exhaust gas discharged from the warehouse space W to the central lane R is discharged to the outside together with the horizontal ventilation of the central lane R. In FIG. 5, the warehouse space W is ventilated by the blowing power of the blower 22 provided in the warehouse space W, but the air supply fan and the exhaust port 23 provided in the air supply port 21 are provided. The warehouse space W may be ventilated by the blowing power of the exhaust fan.
In this way, by combining the ventilation of the warehouse space W with the ventilation by the horizontal ventilation of the central lane R, it is possible to properly ventilate the entire distribution facility 200 while improving the energy saving property.

(2) In the above embodiment, the opening 1b on the upper end side of the vertical duct 1 is opened in the central lane R4 of the uppermost floor F4 and is not directly opened to the outside. It may be configured so that the upper end of the above is extended upward and the opening on the upper end side is opened to the outside. In this case, the air in the central lane R on each floor F flows into the vertical duct 1 and rises, and the raised air is discharged to the outside through the opening on the upper end side.

(3) In the above embodiment, the vertical ducts 1 are distributed and arranged at a plurality of horizontal locations on the central lane R, but the number and installation locations of the vertical ducts 1 can be appropriately modified, for example, a single vertical duct 1. It may be configured to install the vertical duct 1.

(4) In the above embodiment, the openings 1a and 1b of the vertical duct 1 are formed so as to open in a direction substantially perpendicular to the horizontal ventilation direction of the central lane R, thereby forming the openings 1a and 1b. Although it is configured to generate an attractive force in the vertical duct 1 and strengthen the ascending flow in the vertical duct 1, the chimney effect utilizing the temperature difference of the air is used without forming these openings 1a and 1b as the ones that generate the attractive force. It may be configured to generate an ascending flow in the vertical duct 1 only by itself.

(5) In the upper embodiment, the vertical ventilation section is erected over the central lanes R1 to R4 of all floors F1 to F4 from the lowest floor F1 to the uppermost floor F4, and all floors F1 to F4. Although it is composed of a vertical duct 1 having openings 1a and 1b in the central lanes R1 to R4, it may be configured as being erected over a part of the central lanes on a plurality of floors. In this case, the vertical ventilation section extends over the central lane of a specific lower floor (for example, the lowest floor) where insufficient ventilation is likely to occur and the central lane of a specific upper floor (for example, the uppermost floor) where insufficient ventilation is unlikely to occur. It can be constructed so as to have an opening in the central lane of these specific floors, and the insufficient ventilation of the lower floors can be suppressed by the ascending flow in the vertical ventilation section. Further, in arranging the plurality of vertical ventilation portions in the horizontal direction, for example, in each vertical ventilation portion, the upper end opening is to be opened in the central lane of the uppermost floor, and the opening on the lower floor side is opened. May be configured to open into the central lanes of different lower floors.

(6) In the above embodiment, an example in which the ventilation system according to the present invention is applied to distribution facilities 100 and 200 having central lanes R having warehouse spaces W on both sides as horizontal ventilation spaces has been described. It can also be applied to a logistics facility equipped with a lane having a warehouse space as a horizontal ventilation space, and further, it has a plurality of open portions open to the outside, and the outside air is directed in the horizontal direction through the plurality of open portions. As long as it has a horizontal ventilation space that allows ventilation, it may be applied to buildings other than logistics facilities.
