Description

[Technical Field]

[0001] The present invention relates to an air conditioning structure for a building, and more particularly to an air conditioning structure for a building in which a first aisle and a second aisle are arranged, each extending along a row of storage shelves. [Background technology]

[0002] Large buildings such as general factories, warehouses, temporary facilities, and stores tend to have high ceilings and large indoor spaces, which can lead to large temperature differences. For this reason, technologies have been proposed to improve the adverse indoor environment.

[0003] For example, Japanese Patent Application Laid-Open Publication No. 2018-118792 (Patent Document 1) discloses a technology for an air conditioning system equipped with a transportable part that can move a blower unit to any shelf, where the blower unit can be moved above the shelf in the summer when high-temperature hot air accumulates near the ceiling, and below the shelf in the winter when low-temperature cold air accumulates near the floor.

[0004] In addition, Patent Publication No. 2015-190678 (Patent Document 2) discloses an air conditioning system that uses multi-tiered, multi-connected rack columns arranged in a warehouse as air conditioning ducts, and provides multiple air outlets on the rack columns to directly supply conditioned air to items stored in the racks. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-118792 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-190678 Summary of the Invention [Problem to be solved by the invention]

[0006] The air conditioning system of Patent Document 1 can only move the air conditioner to areas with adverse environments. The air conditioning system of Patent Document 2 can only distribute cool air evenly over luggage. Neither document can maintain a comfortable temperature in areas such as corridors where people are staying.

[0007] Additionally, when air conditioning large buildings, floor-standing air conditioners are sometimes used, but in order to transport air over long distances, ducts must be connected to the floor-standing air conditioner itself, which increases the cost of duct construction and complicates the structure of the indoor space.

[0008] The present invention has been made to solve the above-mentioned problems, and its purpose is to provide an air conditioning structure for a building that is simple in structure yet can improve the environment in corridors where people stay. [Means for solving the problem]

[0009] In one aspect of the present invention, an air conditioning structure for a building includes a row of storage shelves arranged between a first wall and a second wall facing the first wall, the row extending in a straight line with the first wall side at one end and the second wall side at the other end, and a first passageway provided on one widthwise side of the row of storage shelves, and a second passageway provided on the other widthwise side of the row of storage shelves. The air conditioning structure includes a first air conditioner that blows conditioned air from the first wall side toward the first passageway, and a second air conditioner that blows conditioned air from the second wall side toward the second passageway, and the first passageway and the second passageway form a circulation path for circulating the conditioned air.

[0010] Preferably, the storage system further comprises a relay unit provided midway along the length of the row of storage shelves, for blowing air from the first wall or second wall side toward the second wall or first wall side.

[0011] Preferably, at least one of the first air conditioner and the second air conditioner is a relay unit.

[0012] Preferably, the air blowing direction of the first air conditioner and the second air conditioner is horizontal or below horizontal.

[0013] Preferably, the air outlet height of the first air conditioner and the second air conditioner is equal to or greater than 2 m and equal to or less than 4 m.

[0014] Preferably, the first air conditioner and the second air conditioner are cooling machines. [Effects of the Invention]

[0015] The building of the present invention has a simple structure, yet can improve the environment of the corridors where people stay. [Brief explanation of the drawings]

[Figure 6] FIG. 10 is a plan view showing the air conditioning structure of a building according to a fourth embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which like reference numerals denote like or corresponding parts and will not be described repeatedly.

[0018] (Embodiment 1) 1 and 2(A), before describing the air conditioning structure of a building according to this embodiment, a building 1 in which the air conditioning structure is installed will be described. The building 1 is a large building, such as a warehouse, a store, a factory, or a temporary facility.

[0019] As shown in Figures 1 and 2(A), the building 1 comprises a floor 10, four walls 11 to 14, and a roof (ceiling wall) 15. The floor 10 is located inside the four walls 11 to 14, and the ceiling wall 15 is supported from below by the four walls 11 to 14. The ceiling wall is a wall that is located vertically above the indoor space 2 and defines the ceiling surface. In this embodiment, the ceiling wall 15 is the roof 15, but if a ceiling is provided, the ceiling may also serve as the ceiling wall.

[0020] 1, the building 1 has, for example, a substantially square shape in plan view, with a first wall 11 and a second wall 12 facing each other, with one end of the first wall 11 and the other end of the second wall 12 connected by a third wall 13 and the other end connected by a fourth wall 14. Note that the walls 11 to 14 may be exterior walls or partition walls that separate the indoor space 2.

[0021] In the building 1, an indoor space 2 is formed by a floor 10, walls 11 to 14, and a roof 15. As shown in FIG. 2(A), the height H1 of the indoor space 2 (the dimension from the floor 10 to the roof 15) is typically 4 m or more and 7 m or less, but may be as large as 10 m or 20 m. As shown in FIG. 1, the floor area of ​​the building 1 is typically 1500 m. 2 Specifically, it is preferable that the dimension L1 between the wall portions 11 and 12 and between the wall portions 13 and 14 is, for example, about 35 m.

[0022] As shown in FIG. 1, a row 20 of multiple storage shelves (hereinafter referred to as storage shelf row 20) is arranged in this indoor space 2. The storage shelf row 20 is arranged between a first wall 11 and a second wall 12, and extends linearly with one end on the first wall 11 side and the other end on the second wall 12 side. The storage shelf row 20 extends parallel to the direction in which the third wall 13 and the fourth wall 14 extend. A plurality of storage shelf rows 20 are provided, and are arranged approximately parallel to each other in the same direction. In FIG. 1, one end of the storage shelf row 20 is arranged at a distance from the first wall 11, but the other end of the storage shelf row 20 is arranged adjacent to the second wall 12. By arranging one end of the storage shelf row 20 at a distance from the first wall 11, a forklift for transporting luggage can be turned around.

[0023] Storage shelf row 20 typically has two rows and includes first storage sections 21 and second storage sections 22, with only one row of first storage sections 21 arranged on third wall 13 and only one row of second storage sections 22 arranged on fourth wall 14. Height H2 (FIG. 2(A)) of storage shelf row 20 is, for example, 2 m or more and 4 m or less, and is typically 3 m. Width L2 (FIG. 1) of storage shelf row 20 is typically 2 m or more and 5 m or less.

[0024] The row of storage shelves 20 is a rack having at least a plurality of pillars and shelves connecting the pillars. Pallets may be placed on the shelves so that stored items can be moved using, for example, a forklift. The first storage section 21 and the second storage section 22 are formed with a plurality of storage sections for storing items such as luggage. The first storage section 21 and the second storage section 22 are arranged back to back and extend linearly in the same direction. Items stored in the storage sections 21 and 22 can be taken in and out from the aisles 31 and 32, respectively, which will be described later.

[0025] As shown in FIG. 1, the storage shelf row 20 forms at least two aisles 31, 32. The first and second aisles 31, 32 are spaces extending in the longitudinal direction, and are enclosed on three sides by the floor 10, the first and second storage sections 21, 22 of the storage shelf row 20, and the items stored therein. The first aisle 31 and the second aisle 32 are adjacent to each other, with the storage shelf row 20 as the boundary. Forklifts for transporting luggage and people pass through the first aisle 31 and the second aisle 32. Therefore, the width L3 (FIG. 1) of the first aisle 31 and the second aisle 32 is typically 2 m or more and 5 m or less.

[0026] A plurality of air conditioners 41, 42 are arranged in the indoor space 2. The first air conditioner 41 blows out conditioned air from the first wall 11 side toward the first passage 31. The second air conditioner 42 blows out conditioned air from the second wall 12 side toward the second passage 32. The first air conditioners 41 and the second air conditioners 42 are arranged alternately on each of the walls 11, 12, with the passages 31, 32 in between, so that the air flows in opposite directions in the adjacent passages 31, 32. This forms a circulation path for circulating the conditioned air between the first passage 31 and the second passage 32. The air flow will be described later.

[0027] The air conditioners 41, 42 are each arranged at an end of the storage shelf row 20. Specifically, the first air conditioner 41 is arranged adjacent to the first wall 11, and the second air conditioner 42 is arranged adjacent to (or abutting) the second wall 12. The air conditioners 41, 42 are typically ceiling-suspended types that are hung from the top wall 15, but they may also be wall-mounted types that are attached to the walls 11, 12, and the type of air conditioner is not limited.

[0028] The air conditioners 41, 42 are installed at a position lower than the height of the storage rack row 20 and higher than the height of a forklift or the like, typically at a position of about 3 m. The air conditioners 41, 42 are, for example, air conditioners, and are typically preferably air conditioners capable of cooling operation. The air conditioners 41, 42 in this embodiment have the same structure, but may also be different.

[0029] As shown in FIG. 2(A), it is preferable that the air intakes and air outlets of the air conditioners 41, 42 are oriented in different directions. Specifically, it is preferable that the airflow direction of the air outlets is horizontal or lower than horizontal, and tilted upward rather than downward vertically. Furthermore, the air outlet height H3 is 2 m or more and 4 m or less, which is slightly higher than the space where people are staying, and is preferably 3 m or less. This allows the conditioned air aired by the air conditioners 41, 42 to be efficiently blown toward the first passage 31 and the second passage 32, preventing the conditioned air from spreading into the space above. It is also preferable that the air intakes are downward.

[0030] The flow of cooling air will be described in detail with reference to FIGS. 2(A) and 2(B).

[0031] As shown in FIGS. 2(A) and 2(B), cooled air is blown out from the second air conditioner 42 disposed on the second wall 12 side toward the second passage 32. The blowing direction of the cooled air blown out from the second air conditioner 42 is horizontal or below the horizontal, so the cooled air flows along the longitudinal direction of the second passage 32. Furthermore, because the specific gravity of the cooled air is high, it flows through the lower part of the second passage 32. As the cooled air approaches the first wall 11 of the second passage 32, it is gradually warmed by the temperature of the indoor space 2. Because the first air conditioner 41 is disposed on the first passage 31 side, the cooled air that reaches the first wall 11 side is drawn into the first air conditioner 41. Because the intake port of the first air conditioner 41 is located downward, it can efficiently draw in the cooled air that has flowed through the lower part.

[0032] As shown in FIG. 2(B), the cool air cooled by the first air conditioner 41 is blown toward the first passage 31. As with the second air conditioner 42, the blowing direction of the cool air blown from the first air conditioner 41 is horizontal or below the horizontal, so the cool air flows along the longitudinal direction of the first passage 31. Furthermore, because the cool air has a high specific gravity, it flows through the lower part of the first passage 31. As the cool air approaches the second wall 12 of the first passage 31, it is gradually warmed by the temperature of the indoor space 2. Because the second air conditioner 42 is disposed on the second wall 12 side, the cool air that reaches the second wall 12 side is drawn into the second air conditioner 42. As with the first air conditioner 41, the intake port of the second air conditioner 42 is located downward, so that the cool air that has flowed through the lower part can be efficiently drawn in.

[0033] In this way, the first passage 31 and the second passage 32 form a circular circulation path for circulating the cool air cooled by the air conditioners 41, 42. As shown in Fig. 1, a plurality of first and second passages 31, 32 are provided in the indoor space 2, so that a plurality of circulation paths are formed.

[0034] The air conditioning structure of this embodiment includes a first air conditioner 41 that blows conditioned air from the first wall portion 11 side toward the first passage 31, and a second air conditioner 42 that blows conditioned air from the second wall portion 12 side toward the second passage 32, and a circulation path is formed by the first passage 31 and the second passage 32, so that only the first passage 31 and the second passage 32 can be air-conditioned. This makes it possible to improve the environment in the first passage 31 and the second passage 32 where people stay, despite the simple structure.

[0035] Furthermore, the airflow direction of the first air conditioner 41 and the second air conditioner 42 is horizontal or below the horizontal, and in particular, the air outlet height of the first air conditioner 41 and the second air conditioner 42 is between 2 m and 4 m, so the area conditioned by the air conditioners 41, 42 is limited to the area where people stay. Therefore, it is possible to efficiently air-condition only the areas where people stay without air-conditioning the entire indoor space 2 of the large building 1, particularly without air-conditioning the upper area on the roof 15 side. Furthermore, the first and second aisles 31, 32 are spaces extending in the longitudinal direction and are enclosed by the floor 10, the storage shelf row 20, and the items stored therein, so the distance that the conditioned air from the air conditioners 41, 42 can reach can be increased.

[0036] If the building 1 is a fairly large warehouse or the like, the longitudinal lengths of the first and second passages 31 and 32 may be long, making it difficult for the air conditioned by the first and second air conditioners 41 and 42 to reach the second and first air conditioners 42 and 41 provided on the opposing wall portions 12 and 11. An embodiment that can be applied even in such a case is shown below.

[0037] (Embodiment 2) Fig. 3(A) is a cross-sectional view showing the air conditioning structure of a building according to the present embodiment 2, and Fig. 3(B) is its plan view. Building 1A according to the present embodiment 2 differs from building 1 according to the first embodiment in that relay units 43A and 46A are provided midway along the longitudinal direction of storage shelf row 20.

[0038] Storage shelf row 20A arranged in building 1A of this embodiment includes first shelf 23A located on the first wall 11 side, second shelf 24A located on the second wall 12 side, and third shelf 25A between first shelf 23A and second shelf 24A. Third shelf 25A is located in the longitudinal center of storage shelf row 20. Relays 43A and 46A are arranged on third shelf 25A.

[0039] The relay unit 43A is provided in contact with the second passage 32 and blows air from the second wall portion 12 toward the first wall portion 11. Specifically, as shown in FIG. 3(B), the relay unit 43A is disposed on the second shelf portions 24A of the first storage unit 21A and the second storage unit 22A facing the second passage 32, and is provided opposite to each other with the second passage 32 interposed therebetween. The relay unit 46A is provided in contact with the first passage 31 and blows air from the first wall portion 11 toward the second wall portion 12. Like the relay unit 43A, the relay unit 46A is disposed on the third shelf portions 25A of the first storage unit 21A and the second storage unit 22A facing the first passage 31, and is provided opposite to each other with the first passage 31 interposed therebetween.

[0040] The relay units 43A, 46A are typically air conditioners that condition air, but they need not necessarily have an air conditioning function as long as they generate an air flow along the air flow at least in the passages 31, 32. As shown in FIG. 3(A), the relay unit 43A includes an intake port 44A provided below and an outlet port 45A provided above the intake port 44A. The outlet port 45A is preferably at approximately the same height as the air outlet height of the first and second air conditioners 41, 42. The outlet port 45A may be, for example, a punker louver, and may be able to change the air blowing direction.

[0041] In this embodiment, relays 43A, 46A are disposed midway along the first passage 31 and the second passage 32, so that air conditioned by the first air conditioner 41 can be relayed by the relay 46A and sent to the second wall portion 12 side to reach the second air conditioner 42, and further, air conditioned by the second air conditioner 42 can be relayed by the relay 43A and sent to the first wall portion 11 side to reach the first air conditioner 41. This makes it possible to efficiently air-condition only the spaces where people are staying, even in buildings where the longitudinal lengths of the passages 31, 32 are long.

[0042] (Variation) 4 is a plan view showing a modified example of relay unit 43A. Intake port 44A and outlet port 45A of relay unit 43A in the second embodiment are provided substantially parallel to the extension direction of passages 31 and 32. However, as shown in FIG. 4, they may be provided at an angle with respect to passages 31 and 32. Specifically, intake port 44B of relay unit 43B may be provided at an angle protruding toward the direction in which conditioned air flows, and outlet port 45B thereof may be provided at an angle recessed toward the direction in which conditioned air flows. This allows relay unit 43B to have a shape that makes it easy to take in air flowing through passages 31 and 32 and to blow it out toward passages 31 and 32.

[0043] (Embodiment 3) 5 is a plan view showing the air conditioning structure of a building according to Embodiment 3. Building 1C according to Embodiment 3 differs from Embodiment 2 in that air conditioner 42 on the second wall portion 12 side is not operated.

[0044] In building 1B of this embodiment, when no items are stored in storage shelf row 20 on the second wall 12 side, no one is staying in that area, so there is no need to air-condition the area where no one is staying. Therefore, operation of air conditioner 42 on the second wall 12 side can be stopped to save energy. Even when operation of air conditioner 42 on the second wall 12 side is stopped, a circulation path for conditioned air can be formed in first passage 31 and second passage 32 on the first wall 11 side.

[0045] The relay unit 47C of this embodiment traverses the storage shelf row 20A in the width direction (vertical direction on the paper) and blows out air from the first passage 31 to the second passage 32. Therefore, the relay unit 47C of this embodiment functions as a "second air conditioner."

[0046] Specifically, the cool air cooled by the first air conditioner 41 is blown out toward the first passage 31 and branches off into the relay unit 47C arranged in the first storage section 21A and the relay unit 47C arranged in the second storage section 22A. The air drawn into the relay unit 43C arranged in the first storage section 21A is blown out toward the second passage 32 and returns to the first air conditioner 41. The relay unit 47C in this embodiment is an air conditioner, and is preferably an air conditioner.

[0047] In this embodiment, the stored items are placed on the first wall 11 side, but they may also be placed on the second wall 12 side. In such a case, the operation of the air conditioner 41 on the first wall 11 side may be stopped, and only the air conditioner 42 on the second wall 12 side may be operated. In that case, the relay unit 47C functions as the "first air conditioner."

[0048] (Fourth embodiment) 6 is a plan view showing the air conditioning structure of a building according to Embodiment 4. Building 1D according to Embodiment 4 differs from Embodiment 2 in that a first wall-side air conditioner 41D on the first wall 11 side and a second wall-side air conditioner 42D on the second wall 12 side are arranged facing each other in the same passages 31, 32.

[0049] In building 1D of this embodiment, a first wall-side air conditioner 41D and a second wall-side air conditioner 42D are arranged facing each other across second passage 32. No air conditioner is arranged in first passage 31 adjacent to second passage 32. Furthermore, a relay unit 47C similar to that in embodiment 3 is arranged in storage shelf row 20A.

[0050] In this embodiment, as in the second embodiment, the relay unit 47C sends air toward the adjacent passage. Specifically, the relay unit 47C in this embodiment takes in air sent from the first wall-side air conditioner 41D to the first passage 31, sends it to the second passage 32, and sends it back to the first wall-side air conditioner 41D. Similarly, the relay unit 47C takes in air sent from the second wall-side air conditioner 42D to the first passage 31, sends it to the second passage 32, and sends it back to the second wall-side air conditioner 42D. This forms two circulation paths between the first passage 31 and the second passage 32. Specifically, the first wall-side air conditioner 41D and the relay unit 47C form a first circulation path on the first wall 11 side, and the second wall-side air conditioner 42D and the relay unit 43C form a second circulation path on the second wall 12 side.

[0051] Therefore, in this embodiment, the first wall-side air conditioner 41D and the second wall-side air conditioner 42D function as the "first air conditioner," and the relay unit 47C functions as the "second air conditioner."

[0052] Although the buildings in the above embodiments have been described as being used in general factories, warehouses, temporary facilities, stores, etc., they may also be used in other buildings, such as office buildings. Specifically, they can be effectively applied to buildings such as libraries and archives, where multiple rows of storage shelves are arranged in the longitudinal direction.

[0053] Furthermore, in this embodiment, an example has been described in which the relay units 43A, 43D are placed on the third shelf section 25A of the storage shelf row 20, but the placement locations of the relay units 43A, 43D are not limited as long as they are placed at a midpoint in the longitudinal direction of the storage shelf row 20. Furthermore, if the relay units 43A, 43D are placed on a pallet, they can be moved to any location using a forklift or the like depending on the storage status of the stored items.

[0054] The above-described embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments, but should be defined by the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included. [Explanation of symbols]
