Description

There is an application for exception of loss of novelty

The present invention relates to a building and a ventilation method for the building, which can efficiently dehumidify the internal space.

Conventionally, in a building such as a warehouse, dew condensation may occur on the floor, wall surface and ceiling surface in winter when the temperature is low or in summer when the humidity is high. In particular, the temperature of the floor surface formed of concrete does not change easily. Therefore, for example, when warm and humid air comes into contact with the cooled floor surface at night, dew condensation occurs. When dew condensation occurs, not only the things stored inside the building deteriorate or corrode due to humidity, but also the workers working inside or the traveling vehicle slip due to the moisture on the floor surface. May cause an accident.

In order to solve the above problems, it is necessary to remove the moisture in the building. According to the warehouse disclosed in Patent Document 1, an air circulator is arranged above the internal space of the warehouse. The air circulator sends air into the gaps between the plurality of stored items. As a result, it is possible to circulate the air in the gaps of the stored items where moisture tends to accumulate, and reduce the humidity in the gaps of the stored items.

Embodiment 1.
FIG. 1 is a plan view of the building 100 according to the first embodiment. FIG. 1 is a plan view schematically showing the internal structure of the building 100. The building 100 is, for example, a warehouse, and the internal space 90 of the building 100 is divided into a plurality of spaces by the internal walls 14 and 15. The internal space 90 and the external space 50 of the building 100 are separated by an external wall 16. The building 100 is not limited to the one composed of one layer of the structure shown in FIG. 1, and is formed by stacking the structure shown in FIG. 1 or other structures in the vertical direction in multiple layers. It may be a thing. Further, the building 100 may have a plurality of rooms inside a factory building, a hotel, a hospital, an apartment house, or the like, in addition to a warehouse.

The building 100 includes a common room 10 and a room 20 formed by partitioning the internal space 90 by the internal walls 14 and 15. In the first embodiment, the chamber 20 includes a plurality of chambers 20a to 20h, and each chamber 20 is arranged adjacent to the common chamber 10. The room 20 and the common room 10 are separated by an internal wall 14. An internal door 17 is installed on the inner wall 14 corresponding to a plurality of rooms 20a to 20h. The internal door 17 is formed so that the chambers 20a to 20h and the common chamber 10 can communicate with each other. In the first embodiment, the plurality of rooms 20a to 20h are storage rooms formed inside the building 100. Further, the internal door 17 is, for example, a shutter or a door installed on the internal wall 14.

(Common room 10)
The common room 10 is arranged in the center of the building 100, and is arranged so as to penetrate the building 100 in the left-right direction in FIG. In the first embodiment, the common room 10 is a roadway provided so that the transport vehicle can reach each of the plurality of rooms 20a to 20h which are storage rooms. That is, a vehicle such as a truck loaded with luggage for storage in the room 20 enters from the outside of the building 100 through one opening 11a of the common room 10, passes through the common room 10, and reaches the room 20. Vehicles such as trucks unload their luggage in the storage room, pass through the common room 10, and go out to the outside of the building 100. One of the two openings 11 in the common room may be referred to as a first opening and the other may be referred to as a second opening.

The common room 10 penetrates across the building 100, and both ends are openings 11a and 11b connecting to the external space 50 of the building 100. External doors 40 are installed in the openings 11a and 11b. The external door 40 is installed so as to partition the common room 10 and the external space 50. In the first embodiment, the outer door 40 is an electric shutter that can be opened and closed at high speed.

The rooms 20a to 20h are independent spaces and are partitioned by a partition wall 15. A temperature control device such as an air conditioner, a dehumidifying device, or the like may be installed in each of the rooms 20a to 20h. The chambers 20a to 20h may have different temperature control and humidity control, and the articles stored inside may also be different.

The plurality of chambers 20 are arranged in parallel along a first direction from one opening 11a of the common chamber 10 toward the other opening 11b. The plurality of chambers 20 are located on both sides of the second direction with respect to the common chamber 10 when the second direction orthogonal to the first direction is defined. The first direction corresponds to the x direction shown in FIG. 1, and the second direction corresponds to the y direction shown in FIG.

Four of the plurality of chambers 20a to 20d are arranged in the x direction along the common chamber 10. Four of the plurality of chambers 20e to 20h are arranged in the x direction so as to face the plurality of chambers 20a to 20d with the common chamber 10 interposed therebetween.

In the first embodiment, each of the plurality of chambers 20 is provided with a truck berth (not shown) inside. The truck berth is a space for parking trucks and loading and unloading luggage. At the back of the truck berth, there is a storage room for storing luggage. The truck berth and the common room 10 which is a roadway are separated by an inner wall 14, but an internal door 17 is installed on the inner wall 14, and the truck berth and the roadway can be separated by opening the inner door 17. You can come and go freely. The internal structure of the plurality of chambers 20 can be appropriately changed, and for example, a truck berth may not be installed.

The internal doors 17 installed corresponding to each of the chambers 20a to 20h are open during the time when a vehicle such as a truck comes in and out, and can be closed at other times. The internal door 17 communicates the common room 10 and the room 20. In the first embodiment, the internal door 17 is a shutter that can be opened and closed, and opens and closes an opening that connects the common room 10 and the room 20. By opening and closing the internal door 17, vehicles such as trucks can enter and exit the room 20.

Further, an air outlet 18 is provided on the inner wall 14 that separates the common room 10 and the room 20. The air outlet 18 is configured to be able to send the air of the common room 10 to the room 20, and may be provided with a blower such as a ventilation fan, or the air may pass from the common room 10 to the room 20. It may be composed of only holes. The air outlet 18 is configured so that the common room 10 and the room 20 communicate with each other even when the internal door 17 is closed, and air flows from at least the common room 10 to the room 20.

Exhaust ports 19 are provided on the outer walls 16a and 16b that separate the chamber 20 and the external space 50. The exhaust port 19 may be provided with a blower such as a ventilation fan, or may be composed of only holes configured so that air can pass from the inside of the chamber 20 to the external space 50.

(External door 40)
FIG. 2 is an enlarged view of the opening 11b according to the first embodiment. Both ends of the common room 10 are openings 11 communicating with the external space 50. As shown in FIG. 2, an external door 40 is installed in the opening 11b. The external door 40 may be formed so as to block the common room 10 and the external space 50. However, in the first embodiment, even when the outer door 40 is closed, the inside of the building 100 is opened with the outer door 40 in order to obtain a predetermined ventilation volume with the outer space 50. A predetermined gap is formed between the portion 11b and the portion 11b. This gap is called a ventilation port 30. In the first embodiment, the ventilation port 30 has a gap that allows a person to pass through, and can be used when a worker or the like enters or exits the building 100. The opening 11a is also configured in the same manner as the opening 11b.

In the first embodiment, the outer door 40 includes two doors, the outer doors 40a and 40b. Since the building 100 is, for example, a warehouse and a transport vehicle such as a truck enters and exits, for example, one external door 40a is used as an exit of the transport vehicle, and the other external door 40b is used as an entrance of the transport vehicle. With this configuration, the area where the opening 11 is opened when the transport vehicle passes can be made as small as possible compared to the building 100 having the external door 40 composed of a single door. In addition, the total time for opening the opening 11 when the transport vehicle is passing can be shortened.

As shown in FIG. 2, dehumidifying devices 31 and 32 are installed at the end of the common chamber 10 near the opening 11b. The dehumidifying devices 31 and 32 are installed, for example, suspended from the ceiling surface. In the first embodiment, the dehumidifying devices 31 and 32 are dehumidifying devices dedicated to dehumidification, but may be configured by an air conditioner having dehumidifying performance, or two types of dehumidifying devices and air conditioners dedicated to dehumidification are installed. May be. The common chamber 10 may be provided with dehumidifying devices 31 and 32 so that the dehumidifying capacity is higher at the end of the common chamber 10 which is closer to the opening 11 than the central portion. This is because the humidity of the air tends to be high in the vicinity of the opening 11 because there is an inflow of air from the external space 50. Further, by lowering the humidity at the end of the common chamber 10 where the humidity of the air tends to be high, it becomes easy to keep the humidity at the center of the common chamber 10 low.

As shown in FIG. 2, a blower 33 may be installed in the common room 10. The blower 33 is configured so that air flows from the end portion of the common chamber 10 whose longitudinal direction is directed in the x direction toward the central portion. Further, the blower 33 may be configured so that air flows toward the floor surface of the common room 10. As a result, the air near the floor surface of the common room 10 can be circulated to reduce the humidity of the air near the floor surface, so that dew condensation on the floor surface can be suppressed.

(Air flow in building 100)
The flow of air in the building 100 will be described with reference to FIGS. 1 and 2. The common chamber 10 is configured so that air flows in from the external space 50 through the openings 11a and 11b. When the outer door 40 is open, air flows in through the opening formed by the opened outer door 40, and when the outer door 40 is closed, air flows in through the ventilation port 30. In the first embodiment, as shown in FIG. 2, the dehumidifying devices 31 and 32 installed at the end of the common chamber 10 have a wind direction so that air flows from the end of the common chamber 10 toward the center. Is set. With this configuration, the air dehumidified by the dehumidifying devices 31 and 32 flows toward the central portion of the common chamber 10 and does not flow out from the opening 11 to the external space 50. Therefore, the common room 10 is efficiently dehumidified.

However, the dehumidifying device 31 installed in front of the chambers 20a, 20d, 20e, and 20h closest to the opening 11 may have the wind direction set toward the chamber 20. Arrows 34a and 34b in FIG. 2 indicate the flow of air dehumidified by the dehumidifying device 31, and the air indicated by the arrow 34a tends to flow into the chamber 20d. Further, the air indicated by the arrow 34b tends to flow into the chamber 20h. With such a configuration, dehumidified air easily flows into the chambers 20d and 20h closest to the opening 11b. That is, even in the room 20 closest to the external space 50, it is possible to suppress the inflow of the dehumidified air in the common room 10 and the direct inflow of the air in the external space 50. Therefore, the humidity of the air inside the chambers 20d and 20h can be suppressed.

The air in the common chamber 10 flows into the plurality of chambers 20 as indicated by the arrow 12. The air flow indicated by the arrows 12a to 12h flows into each of the chambers 20a to 20h through the open internal door 17, or when the internal door 17 is closed, the air flow passes through the air outlet 18 to the chambers 20a to 20h. Inflow into each of. Each of the chambers 20a to 20h is provided with an exhaust port 19 on the outer walls 16a and 16b separated from the external space 50. The air inside the chambers 20a to 20h is discharged from the exhaust port 19 to the external space 50 as shown by the arrows 21a to 21h in FIG.

The chambers 20a to 20h are configured such that air flows in from the common chamber 10 and air flows out to the external space 50, respectively. Specifically, in the building 100, air flows from the common room 10 installed in the ventilation port 18 to the room 20 and the room 20 installed in the exhaust port 19 to the external space 50. It comprises at least one of the blowers configured to flow.

When the blower is provided only in the air vent 18, the air in the common room 10 is sucked into the room 20 through the air port 18, and the air inside the room 20 is pushed out from the exhaust port 19 to the external space 50.

When the blower is provided only in the exhaust port 19, the air inside the chamber 20 is sucked into the external space 50 through the exhaust port 19, and the air in the common room 10 is sucked into each of the plurality of chambers 20 through the blow port 18. Is done.

That is, in the building 100, the following ventilation method is implemented. Ventilation of a building 100 including a room 20 formed in an internal space and a common room 10 to which the room 20 is connected, and an external door 40 installed in an opening 11 that communicates with the common room 10 and the external space 50. In the ventilation method, the air inside the common room 10 is dehumidified, and the air flows from the common room 10 to the external space 50 via the room 20.

In the interior of the building 100, a device that allows air to flow from the common room 10 to the external space 50 via the plurality of rooms 20 is called an exhaust device. The exhaust device is installed in a blower port 18, an exhaust port 19, a blower port 18 or an exhaust port 19, and is installed in a common chamber 10 to generate an air flow from an opening 11 toward a central portion of the common chamber 10. Blowers, etc. are applicable. The exhaust device is not limited to the form described above, and is not limited to the above, as long as it is configured to allow at least the air inside the building 100 to flow from the common room 10 to the external space 50 via the plurality of rooms 20. It can also take the form of. Since the exhaust device allows air to flow from the common room 10 to the external space 50 via the room 20, as a result, the air in the external space 50 is taken into the common room 10 from the opening 11. The exhaust device circulates and ventilates the air inside the building 100.

(Effect of Embodiment 1)
As described above, in the building 100, air flows from the external space 50 through the opening 11 into the common room 10, the air in the common room 10 flows into each of the plurality of rooms 20, and the external space from the plurality of rooms 20. It is configured so that air is discharged to 50. At this time, the blower may be installed in either the blow port 18 or the exhaust port 19. That is, as shown in FIG. 1, the air flow of the building 100 is configured to flow in the order of the external space 50, the opening 11, the common room 10, the room 20, the exhaust port 19, and the external space 50. .. As a result, the air in the highly humid external space 50 is intensively dehumidified in the common room 10, and only the dehumidified air in the common room 10 flows into the plurality of rooms 20. Therefore, the building 100 can suppress the humidity of the plurality of rooms 20 without taking measures such as individually installing or enhancing the dehumidifiers in each of the plurality of rooms 20. For example, in a warehouse, the humidity of a plurality of storage rooms can be adjusted only by adjusting the humidity of the common room 10, which tends to have the highest humidity, so that the humidity can be suppressed without changing the equipment inside the plurality of storage rooms. Will be.

Further, even when improving the dehumidifying capacity of the existing building 100, simply installing the dehumidifying devices 31 and 32 in the common room 10 and installing the blower in the air vent 18 or the exhaust port 19 is sufficient to install the above-mentioned exterior. The air flowing in the order of the space 50, the opening 11, the common room 10, the room 20, the exhaust port 19, and the external space 50 can flow. As a result, when the building 100 is an existing warehouse, it is not necessary to change the internal equipment of the plurality of rooms 20. Therefore, it is not necessary to move the articles inside the room 20 which is the storage room, and the dehumidifying measures work of the building 100 can be performed while maintaining the normal operating state of the storage room. In addition, it is possible to shorten the construction period of the dehumidification countermeasure construction of the building 100.

The external door 40 is not limited to the shutter, but may be an air curtain, a sheet covering the opening 11, or the like. However, when the shutter is used as in the first embodiment, there is an advantage that a large amount of air in the external space 50 can be suppressed from flowing into the common room 10 when the external space 50 has a strong wind due to the weather. For example, if the opening 11 faces an environment that is not affected by the weather, it is possible to apply an air curtain or a sheet to the outer door 40.

Further, if the building 100 is configured so that air flows in the order of the external space 50, the opening 11, the common room 10, the room 20, the exhaust port 19, and the external space 50, a blower that causes the air flow. The installation position of the can be changed as appropriate. By installing a blower at the exhaust port 19 as in the building 100 according to the first embodiment, there is an advantage that it is possible to suppress the inflow of outside air directly from the external space 50 into the room 20.

In the first embodiment, the building 100 in which the common room 10 and the room 20 are arranged in the horizontal direction has been described. However, in the building 100, for example, the rooms 20 are arranged vertically and the common room 10 is arranged in the room 20. It may be arranged so as to extend in the vertical direction along the arrangement. In this case, the common room 10 is not a passage through which a transport vehicle passes, but is composed of, for example, a space in which an elevator moves up and down. Even in this case, the humidity of the room 20 can be efficiently adjusted by the exhaust device flowing air in the order of the external space 50, the opening 11, the common room 10, the room 20, the exhaust port 19, and the external space 50. Can be done.

The present invention is not limited to the configuration of the above-described embodiment. In short, I would like to add that the gist (technical scope) of the present invention also includes various changes, applications, and uses made by those skilled in the art as necessary.
