[0018] <Current Situation> In recent years, structures have been used in which plants or mushrooms are cultivated, livestock are raised, aquatic organisms are farmed, products are stored, or servers are installed. To maintain a predetermined environment (temperature, humidity, etc.) inside the structure where the plants or mushrooms, livestock, aquatic organisms, products, and servers reside, air conditioning is performed for the interior of the structure. This has resulted in a problem in that a large amount of energy is used for air conditioning the interior of the structure. Below, an embodiment of an example of a variable structure that contributes to solving the above problem will be described.

[0019] In the following embodiments, front means the X direction, rear means the negative X direction, left means the negative Z direction, right means the Z direction, bottom means the negative Y direction, and top means the Y direction. Depth is the length in the X direction. Width is the length in the Z direction. Height is the distance from the floor in the Y direction. In the following embodiments, the floor is approximately horizontal. Therefore, being approximately perpendicular to the floor means being approximately vertical. Being approximately parallel to the floor means being approximately horizontal. A perspective view is a view from diagonally above. A front view is a view from the front. A rear view is a view from the rear. A left side view is a view from the left. A right side view is a view from the right. A plan view is a view from above.

[0020] In the following embodiments, structures include buildings and structures. A building is a structure fixed to land that has a roof and pillars or walls. A structure is an artificial object fixed to land. A hose is a pipe that carries a fluid such as air, and includes so-called "ducts." In the following embodiments, a component of a plane may be a component whose entire plane is curved or partly curved. Blocking includes not only being completely blocked, but also making it difficult to pass through. For example, blocking A and B includes making it difficult to pass from B to A because a wall is covering the area between A and B.

[0021] In the following embodiments, the fact that a plant is being cultivated does not necessarily mean that the plant is always present. The fact that a plant is being cultivated includes the case where the plant is not present after it has been harvested. The fact that a plant is being cultivated also includes the case where the plant is present but cannot be seen with the naked eye. The state of the plant depicted in the drawings is that where it has finished growing. In the following embodiments, the greenhouse may be a greenhouse (such as a glass greenhouse or a plastic film greenhouse). The greenhouse may or may not be a building.

[0022] <First embodiment> (1) Overall configuration The overall configuration of the facility 1 according to the first embodiment will be described. Fig. 1 is a schematic diagram showing the overall configuration of the facility 1. The facility 1 mainly includes a greenhouse 10 and an air conditioner 11.

[0023] (1-1) Greenhouse A greenhouse 10 is a structure in which a frame is constructed and the top is covered with vinyl or the like for cultivating plants P. Plants P are cultivated inside the greenhouse 10. The inside of the greenhouse 10 is mainly provided with a structure 100A and a structure 100B. The inside of the greenhouse 10 is divided into an inside I1 of the structure 100A, an inside I2 of the structure 100B, and a space I3. The space I3 is outside the structures 100A and 100B and is inside the greenhouse 10. Details of the structures 100A and 100B will be described later. The greenhouse 10 mainly has an entrance / exit 101, a passage 102, and one or more lights (not shown).

[0024] (1-1-1) Entrance / Exit The entrance / exit 101 is an entrance through which people or equipment planning to perform agricultural work move from the outside of the greenhouse 10 to the inside of the greenhouse 10. The entrance / exit 101 is also an exit through which people or equipment that have completed agricultural work move from the inside of the greenhouse 10 to the outside of the greenhouse 10. The entrance / exit 101 may have an openable / closable structure (opening) or an open structure (opening). The greenhouse 10 may have multiple entrances / exits 101.

[0025] Agricultural work is work performed by a person or machine on a plant P. Examples of agricultural work include sowing work, which is the work of planting seeds or seedlings of the plant P, cultivation work, which is work performed to grow the plant P (watering, spraying pesticides, pruning, spreading fertilizer, insect repellent, etc.), harvesting work, which is the work of harvesting all or part of the plant P, soil work, which is the work of preparing the soil and plowing, nutrient solution work, which is the work of storing or exchanging nutrient solution, and other agricultural work.

[0026] (1-1-2) Passageway The passageway 102 is a passageway used by people or equipment when agricultural work is being carried out, and is a passageway outside the structure 100A and the structure 100B.

[0027] (1-2) Air Conditioner The air conditioner 11 conditions the inside I1 and the inside I2. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. The air outlet of the air conditioner 11 communicates with the inside I1 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I2 via a hose (not shown) that is different from the hose that communicates with the inside I1. The hose that communicates with the air outlet of the air conditioner 11 and the inside I1, and the hose that communicates with the air outlet of the air conditioner 11 and the inside I2 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I1 and the inside I2 via the hoses.

[0028] The location where the air conditioner 11 is installed is not limited to the outside of the greenhouse 10. The air conditioner 11 may be installed in at least one of the inside I1, the inside I2, and the space I3.

[0029] (2) Detailed Configuration The detailed configuration of the structure 100A and the structure 100B will be described. The structure 100A is a variable structure whose configuration can be changed by the operation of the structure 100A. The structure 100B is a variable structure whose configuration can be changed by the operation of the structure 100B. A variable structure is a structure whose configuration can be changed. The structures of the structure 100A and the structure 100B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 100A and the structure 100B are similar. The structure and function of the structure 100A will be described below.

[0030] FIG. 2 is a perspective view showing the detailed configuration of the structure 100A. FIG. 3 is a front view showing the detailed configuration of the structure 100A. FIG. 4 is a rear view showing the detailed configuration of the structure 100A. FIG. 5 is a left side view showing the detailed configuration of the structure 100A. FIG. 6 is a right side view showing the detailed configuration of the structure 100A. FIG. 7 is a plan view showing the detailed configuration of the structure 100A. The structure 100A mainly has a front wall 110, a third guide rail 111, a fourth guide rail 112, and a ceiling 150.

[0031] The left and right ends of the third guide rail 111 are fixed to the vertical wall V of the greenhouse 10. The third guide rail 111 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "third front rail." Of the two rows of rails, the rear rail is referred to as the "third rear rail."

[0032] The fourth guide rail 112 faces the third guide rail 111. The left and right ends of the fourth guide rail 112 are fixed to the vertical wall V of the greenhouse 10. The fourth guide rail 112 includes two rows of rails aligned in the X direction and extending in the Z direction. Of the two rows of rails, the front rail is referred to as the "fourth front rail." Of the two rows of rails, the rear rail is referred to as the "fourth rear rail." The third front rail and the fourth front rail face each other. The third rear rail and the fourth rear rail face each other.

[0033] The front wall 110 is mainly composed of two slats SL. The two slats SL are approximately perpendicular to the floor F. The two slats SL are guided by a third guide rail 111 and a fourth guide rail 112 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 111 and the fourth guide rail 112 extend). The configuration of the front wall 110 can be changed by the two slats SL sliding while being guided by the third guide rail 111 and the fourth guide rail 112.

[0034] Of the two slats SL that make up the front wall 110, the left slat SL will be referred to as the "left slat SL" and the right slat SL will be referred to as the "right slat SL." The left slat SL can move left and right by sliding it between the third front rail and the fourth front rail. The right slat SL can move left and right by sliding it between the third rear rail and the fourth rear rail. The two slats SL are not connected to each other and can slide independently of each other. The two slats SL are arranged so that they do not overlap (collide with) each other when moving left and right.

[0035] The front wall 110 faces the aisle 102. The left and right ends of the front wall 110 may contact the vertical wall V. In other words, the left end of the left slat SL may contact the vertical wall V. The right end of the right slat SL may contact the vertical wall V.

[0036] The ceiling 150 faces the floor F, contacts the front wall 110, and is an example of a first component. The left end, right end, and rear end of the ceiling 150 are fixed to the vertical wall V. The ceiling 150 is provided with an opening 151 that communicates with a hose. The ceiling 150 also is provided with an opening 152 that communicates with the outside of the structure 100A.

[0037] The opening 151 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I1 via the air outlet of the air conditioner 11, a hose, and the opening 151. The opening 151 may be provided in the front wall 110. The opening 151 may be provided to the right of the approximate center of the structure 100A in the Z direction. The opening 151 may be provided forward of the approximate center of the structure 100A in the X direction. The opening 152 is an example of an exhaust port.

[0038] The air inside I1 is discharged from inside I1 to the outside of the structure 100A through the opening 152. For example, the opening 152 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 152 is an example of a second hose. The air inside I1 flows into the air intake of the air conditioner 11 through the opening 152 and the hose.

[0039] The opening 152 may be provided in the front wall 110. The opening 152 may be provided to the left of approximately the center of the structure 100A in the Z direction. The opening 152 may be provided behind approximately the center of the structure 100A in the X direction. The opening 152 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0040] The interior I1 is formed by surrounding the area of ​​the floor F where the plant P is grown with the front wall 110, the ceiling 150, and the vertical wall V. Specifically, the front side of the area of ​​the floor F where the plant P is grown is surrounded by the front wall 110. The vertical wall V surrounds the left side, right side, and rear side of the area of ​​the floor F where the plant P is grown. The ceiling 150 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0041] The inside I1 is isolated from the outside of the structure 100A and the passage 102 by the front wall 110, the ceiling 150, and the vertical wall V. The space between the inside I1, the outside of the structure 100A, and the passage 102 is covered by the front wall 110, the ceiling 150, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 100A and the passage 102 to the inside I1. Therefore, air supplied to the inside I1 by the opening 151 is unlikely to flow from the inside I1 to the outside of the structure 100A. Air in space I3 is also unlikely to flow to the inside I1. It is difficult for people or equipment to approach the inside I1. People or equipment cannot secure work space. Work space is the space necessary for agricultural work.

[0042] Plants P are grown on the inside I1. A portion of the floor F on the inside I1 is filled with soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be soaked. On the inside I1, the plants P are planted in soil or soaked in the nutrient solution. Examples of the configuration of the ceiling 150 and the slats SL include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0043] The front wall 110 (two slats SL) and the ceiling 150 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I3 is transmitted to the inside I1. Because the front wall 110 (two slats SL) and the ceiling 150 are transparent or semi-transparent, the plants P on the inside I1 can be seen through from the outside of the structure 100A.

[0044] The depth of the structure 100A is a value that ensures D1. D1 is the shortest distance in the X direction from the plant P to the front wall 110 when the plant P has finished growing. D1 is preferably 1 to 10 centimeters, but is not limited to this. The height of the structure 100A is a value that ensures D2. D2 is the shortest distance in the Y direction from the plant P to the ceiling 150 when the plant P has finished growing. D2 is preferably 1 to 10 centimeters, but is not limited to this. The width of the structure 100A is the same as the width of the interior of the greenhouse 10.

[0045] The ceiling 150 is a component that cannot be changed in shape. The front wall 110 is a component that can be changed in shape. Therefore, the structure 100A is a variable structure. Note that the ceiling 150 may be a component that can be changed in shape.

[0046] The structure 100A may further include a floor material (not shown). The floor material is in contact with the front wall 110 and the vertical wall V. The floor material is laid on the floor F of the inner side I1 (all or part of the floor F of the inner side I1). The opening 151 may be provided in the floor material. The opening 152 may be provided in the floor material. The inner side I1 is formed by being surrounded by the floor material in addition to the front wall 110, the ceiling 150, and the vertical wall V.

[0047] Various aspects of the structure 100A will be described below. Fig. 8 is a perspective view showing a detailed configuration of the structure 100A. The aspect of Fig. 8 is an aspect in which the left slat SL has been slid in the Z direction from the aspects of Figs. 2, 3, 4, 5, 6, and 7.

[0048] The left slat SL has been slid in the Z direction so that it is generally aligned with the right slat SL in the X direction. The inside I1 is now connected to the outside of the structure 100A and the passage 102 through the left front side of the structure 100A. By changing the configuration of the front wall 110, the state in which the outside of the structure 100A and the passage 102 were blocked from the inside I1 has been changed to a state in which the outside of the structure 100A and the passage 102 are connected to the inside I1. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 100A.

[0049] Fig. 9 is a perspective view showing the detailed configuration of the structure 100A. In the state shown in Fig. 9, the right slat SL is slid in the minus Z direction from the states shown in Figs. 2, 3, 4, 5, 6, and 7.

[0050] Because the right slat SL has been slid in the negative Z direction, it is generally aligned with the left slat SL in the X direction. The inside I1 is now connected to the outside of the structure 100A and the passage 102 through the right front side of the structure 100A. By changing the configuration of the front wall 110, the state in which the outside of the structure 100A and the passage 102 were blocked from the inside I1 has been changed to a state in which the outside of the structure 100A and the passage 102 are connected to the inside I1. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 100A.

[0051] 2, 3, 4, 5, 6, and 7 are also modes in which the left slat SL has been slid in the minus Z direction from the mode in Fig. 8. By changing the mode of the front wall 110, the state in which the outside of the structure 100A and the passage 102 are connected to the inside I1 is changed to a state in which the outside of the structure 100A and the passage 102 are blocked from the inside I1.

[0052] 2, 3, 4, 5, 6, and 7 are also modes in which the right slat SL has been slid in the Z direction from the mode of Fig. 9. By changing the mode of the front wall 110, the state in which the outside of the structure 100A and the passage 102 are connected to the inside I1 is changed to a state in which the outside of the structure 100A and the passage 102 are blocked from the inside I1.

[0053] (3) Operation The operation of the equipment 1 when a person or device performs harvesting work will be described. Since the operation of the structure 100A and the operation of the structure 100B are similar, the operation of the structure 100A will be mainly described. Figure 10 is a flowchart showing the operation of the equipment 1. Air heated by the air conditioner 11 is supplied to the inside I1 through the hose and the opening 151. The structure 100A is the same as the structure 100A shown in Figures 2, 3, 4, 5, 6, and 7.

[0054] Two slats SL cover the front side of the structure 100A, isolating the outside of the structure 100A and the passage 102 from the inside I1. The heated air supplied to the inside I1 does not easily flow to the outside of the structure 100A. The temperature of the inside I1 is maintained higher than the temperature of the space I3. Therefore, the inside I1 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting (a state in which they have finished growing).

[0055] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 at the front of the structure 100A. The person or device applies a force in the Z direction to the left slat SL of the two slats SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the Z direction. The left slat SL is guided by the third guide rail 111 and the fourth guide rail 112 and slides in the Z direction (step S1).

[0056] Because the left slat SL has been slid in the Z direction, the left slat SL is generally aligned with the right slat SL in the X direction. The structure 100A is changed to the state shown in Figure 8 (step S2). The left front side of the structure 100A connects the outside of the structure 100A and the passage 102 with the inside I1. Now that a working space has been secured, a person or device can perform harvesting work on the plants P on the left side. The person or device begins harvesting work on the plants P on the left side.

[0057] When the harvesting work on the plants P on the left side is completed, a person or device applies a force in the minus Z direction to the left slat SL. Because the left slat SL and the right slat SL are independent, only the left slat SL receives the force in the minus Z direction. The left slat SL is guided by the third guide rail 111 and the fourth guide rail 112 and slides in the minus Z direction (step S3).

[0058] Because the left slat SL has been slid in the minus Z direction, the state of the structure 100A is changed to the state shown in Figures 2, 3, 4, 5, 6, and 7 (step S4). Because the left front side of the structure 100A is covered by the left slat SL, the outside of the structure 100A and the passage 102 are blocked from the inside I1.

[0059] A person or device applies a force in the negative Z direction to the right slat SL of the two slats SL. Because the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the negative Z direction. The right slat SL is guided by the third guide rail 111 and the fourth guide rail 112 and slides in the negative Z direction (step S5).

[0060] Because the right slat SL has been slid in the negative Z direction, the right slat SL is generally aligned with the left slat SL in the X direction. The structure 100A is changed to the state shown in Figure 9 (step S6). The right front side of the structure 100A connects the outside of the structure 100A and the passage 102 with the inside I1. Now that a working space has been secured, a person or device can harvest the plants P on the right side. The person or device begins harvesting the plants P on the right side.

[0061] When the harvesting work on the right-side plants P is completed, a person or device applies a force in the Z direction to the right slat SL. Because the right slat SL and the left slat SL are independent, only the right slat SL receives the force in the Z direction. The right slat SL is guided by the third guide rail 111 and the fourth guide rail 112 and slides in the Z direction (step S7).

[0062] Because the right slat SL has been slid in the Z direction, the state of the structure 100A is changed to the state shown in Figures 2, 3, 4, 5, 6, and 7 (step S8). Because the right front side of the structure 100A is covered by the right slat SL, the outside of the structure 100A and the passage 102 are blocked from the inside I1.

[0089] (4-7) Modification 1G The front wall 110 of the first embodiment and modifications 1A, 1B, 1C, 1D, 1E, and 1F may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by the control device.

[0090] (5) Features (5-1) A variable structure is installed inside another structure. In the insides I1 and I2 of the variable structure, plants P or mushrooms M are cultivated, livestock L are raised, aquatic organisms Q are farmed, merchandise G is stored, or a server SV is installed. The variable structure has a front wall 110 and a supply port. The front wall 110 can be changed in shape and erected inside. The supply port is an opening that supplies conditioned air from an air conditioner 11 outside the variable structure to the insides I1 and I2, and is an opening that communicates with a first hose that communicates with the air conditioner 11. The insides I1 and I2 of the variable structure are formed by being surrounded by at least the front wall 110 and at least one of a vertical wall V of the other structure and the ceiling of the other structure. By changing the state of the front wall 110, the state in which the outside of the variable structure is isolated from the insides I1 and I2 is changed to a state in which the outside is communicated with the insides I1 and I2.

[0091] When plants are grown inside a structure, the interior of the structure is air-conditioned to create an environment suitable for plant cultivation. The amount of energy required for air conditioning correlates with the volume of the structure's interior. Because plant cultivation requires work on the plants, the space required for work is secured inside the structure. In non-variable structures whose configuration cannot be changed, the space required for work is secured even when no work is being performed. Therefore, unnecessary space is air-conditioned during times when no work is being performed. This increases the amount of energy required for plant cultivation inside the structure, leading to increased costs for plant cultivation.

[0092] The variable structure is installed inside another structure, and plants are grown inside I1 and I2. The variable structure can reduce the target of air conditioning from the inside of the other structure to I1 and I2. Therefore, the variable structure can achieve energy savings in growing plants P and reduce costs associated with growing plants P.

[0093] The state in which the outside of the variable structure is isolated from the insides I1 and I2 can be changed to a state in which the outside of the variable structure is connected to the insides I1 and I2. The state in which no working space is secured can be changed to a state in which a working space is secured. Therefore, the variable structure allows people or equipment to work on plants P, etc. on the insides I1 and I2.

[0094] The insides I1 and I2 are formed by the vertical walls V of other structures, etc. The variable structure forms the insides I1 and I2 using less material than when the insides I1 and I2 are formed without utilizing other structures. Therefore, the variable structure can reduce material costs while realizing energy savings in the cultivation of plants P, etc., and can reduce the costs associated with the cultivation of plants P, etc.

[0095] Other structures may be vulnerable to physical external forces. Therefore, external forces such as strong winds and typhoons, or external forces such as accumulated snow may damage the other structures. The variable structure and the other structures are interconnected to form the inside I1 and the inside I2. When the other structures are subjected to external forces, the external forces are also distributed to the variable structure. Therefore, the variable structure can protect the other structures and plants P, etc., from physical external forces.

[0096] (5-2) The variable structure further includes a first component in contact with the front wall 110. The first component is a ceiling 150 in contact with the front wall 110. The inside I1 and the inside I2 are formed by being surrounded by at least the front wall 110, the first component, and at least one of a vertical wall V of another structure and a ceiling of another structure.

[0097] In addition to the front wall 110, the variable structure can separate the outside of the variable structure from the insides I1 and I2 by the ceiling 150. Therefore, the variable structure can further reduce the scope of air conditioning. The variable structure can achieve energy savings in the cultivation of plants P, etc., and can reduce the costs associated with the cultivation of plants P, etc.

[0098] When other structures are subjected to external force, the external force is distributed to the ceiling 150 in addition to the front wall 110. Therefore, the variable structure can protect other structures and plants P, etc. from physical external forces.

[0099] (5-3) The front wall 110 of the variable structure faces the outer passage 102. The passage 102 is used by people or equipment when the people or equipment work on any of the plants P or mushrooms M, livestock L, aquatic organisms Q, merchandise G, or server SV. By changing the configuration of the front wall 110, the passage 102 can be changed from a state in which the passage 102 is blocked from the insides I1 and I2 to a state in which the passage 102 is connected to the insides I1 and I2.

[0100] The front wall 110 is likely to receive force from a person or device in the passage 102. Therefore, the variable structure allows a person or device to easily change the state of the front wall 110. The variable structure also makes it easier for a person or device to access the plants P from the passage 102. Therefore, the variable structure makes it easier for a person or device to work on the plants P, etc.

[0101] (5-4) The variable structure further includes an exhaust port, which is an opening for discharging the air in the insides I1 and I2 from the insides I1 and I2 to the outside.

[0102] As air is supplied to the inside of a structure, the air inside the structure may be exhausted through gaps in the structure. In this case, the air cannot be smoothly exhausted, causing a problem of rising air pressure inside. Also, the gaps in the structure may open up over time. Furthermore, the air flow inside the structure may become random depending on the location of the gaps, causing uneven temperature or humidity.

[0103] The variable structure discharges the air inside I1 and I2 from inside I1 and inside I2 to the outside of the variable structure. Therefore, the variable structure can keep the air pressure and airflow inside I1 and inside I2 stable. Also, the variable structure can maintain its airtightness for a longer period of time.

[0104] (5-5) The exhaust port of the variable structure is connected to a second hose that is connected to the intake port of the air conditioner 11 .

[0105] The air supplied from the air conditioner 11 to the insides I1 and I2 through the supply port is discharged again to the intake port of the air conditioner 11. The air circulating between the air conditioner 11 and the insides I1 and I2 is less likely to flow into the space I3. The air conditioner 11 can limit the air to be conditioned to the air circulating between the air conditioner 11 and the insides I1 and I2. Therefore, the variable structure can achieve energy savings in the cultivation of plants P, etc., and can reduce the costs associated with the cultivation of plants P, etc.

[0106] (5-6) The supply port of the variable structure is provided substantially vertically above the center of the variable structure in the vertical direction.

[0107] To create an environment suitable for server operation, the space where the server is installed may be air-conditioned or dehumidified. Cooled air is heavier than uncooled air, so it moves from top to bottom. Dehumidified air is also heavier than unhumidified air, so it moves from top to bottom.

[0108] The variable structure has a supply port located approximately vertically above the approximate vertical center of the variable structure. When cooled air or dehumidified air is supplied to the supply port, the cooled air or dehumidified air moves from approximately vertically above to approximately vertically below. The variable structure creates an airflow on the insides I1 and I2, making it less likely that temperature or humidity variations will occur on the insides I1 and I2. Therefore, the variable structure makes the insides I1 and I2 an environment more suitable for operating the server SV, etc.

[0109] <Second embodiment> (1) Overall configuration The overall configuration of the facility 2 according to the second embodiment will be described. Below, similarities between the first and second embodiments will be omitted, and differences between the first and second embodiments will be mainly described. Fig. 17 is a schematic diagram showing the overall configuration of the facility 2 according to the second embodiment. The facility 2 mainly includes a greenhouse 10 and an air conditioner 11.

[0110] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 200A and a structure 200B. The interior of the green house 10 is divided into an inside I4 of the structure 200A, an inside I5 of the structure 200B, and a space I6. The space I6 is outside the structures 200A and 200B and is inside the green house 10. Details of the structure 200A and the structure 200B will be described later.

[0111] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I4 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I5 via a hose (not shown) that is different from the hose that communicates with the inside I4. The hose that communicates with the air outlet of the air conditioner 11 and the inside I4 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I5 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I4 and the inside I5 via the hoses.

[0112] (2) Detailed Configuration The detailed configuration of the structure 200A and the structure 200B will be described. The structure 200A is a variable structure that can change the state of the structure 200A by operating the structure 200A. The structure 200B is a variable structure that can change the state of the structure 200B by operating the structure 200B. The structures of the structure 200A and the structure 200B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 200A and the structure 200B are similar. The structure and function of the structure 200A will be described below.

[0113] Fig. 18 is a perspective view showing the detailed configuration of structure 200A. Fig. 19 is a front view showing the detailed configuration of structure 200A. Fig. 20 is a rear view showing the detailed configuration of structure 200A. Fig. 21 is a left side view showing the detailed configuration of structure 200A. Fig. 22 is a right side view showing the detailed configuration of structure 200A. Fig. 23 is a plan view showing the detailed configuration of structure 200A.

[0114] The structure 200A mainly has a front wall 210, a third guide rail 111, and a fourth guide rail 112. The structures and functions of the third guide rail 111 and the fourth guide rail 112 are the same as those in the first embodiment, and therefore will not be described.

[0115] The front wall 210 is mainly composed of two slats SL and an upper plate 211. The structure and function of the slats SL are the same as those in the first embodiment, and therefore a description thereof will be omitted.

[0116] The lower end of the upper plate 211 contacts the fourth guide rail 112. The upper end of the upper plate 211 contacts the ceiling C of the greenhouse 10. The left and right ends of the upper plate 211 contact the vertical wall V.

[0117] An opening 251 that communicates with a hose (not shown) is provided in the upper plate 211. The upper plate 211 also has an opening 252 that communicates with the outside of the structure 200A.

[0118] The opening 251 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I4 through the opening 251. The opening 251 may be provided in the slat SL. The opening 251 may be provided to the right of the approximate center in the Z direction of the structure 200A. The opening 252 is an example of an exhaust port.

[0119] The air on the inside I4 is discharged from the inside I4 to the outside of the structure 200A through the opening 252. For example, the opening 252 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 252 is an example of a second hose. The air on the inside I4 flows into the air intake of the air conditioner 11 via the opening 252 and the hose.

[0120] The opening 252 may be provided in the slat SL. The opening 252 may be provided to the left of approximately the center of the structure 200A in the Z direction. The opening 252 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11. The front wall 210 faces the passage 102.

[0121] The area of ​​the floor F where the plants P are grown is surrounded by the front wall 210, the ceiling C, and the vertical wall V, thereby forming an inside I4. Specifically, the front wall 210 surrounds the front side of the area of ​​the floor F where the plants P are grown. The vertical wall V surrounds the left, right, and rear sides of the area of ​​the floor F where the plants P are grown. The ceiling C surrounds the upper side of the area of ​​the floor F where the plants P are grown.

[0122] The inside I4 is isolated from the outside of the structure 200A and the passage 102 by the front wall 210, the ceiling C, and the vertical wall V. The space between the inside I4, the outside of the structure 200A, and the passage 102 is covered by the front wall 210, the ceiling C, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 200A and the passage 102 to the inside I4. Therefore, air supplied to the inside I4 by the opening 251 is unlikely to flow from the inside I4 to the outside of the structure 200A. Air in the space I6 is also unlikely to flow to the inside I4. It is difficult for people or equipment to approach the inside I4. People or equipment cannot secure a working space.

[0123] Plants P are grown in the inner part I4. A part of the bed F in the inner part I4 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I4, the plants P are planted in soil or immersed in the nutrient solution.

[0124] Examples of the configuration of the upper plate 211 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0125] The upper plate 211 includes a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I6 can be transmitted to the inside I4. Because the upper plate 211 is transparent or semi-transparent, the plants P on the inside I4 can be seen through from the outside of the structure 200A.

[0126] The structure 200A is installed so that D9 is ensured. D9 is the shortest distance in the X direction from the plant P to the front wall 310 when the plant P has finished growing. D9 is preferably 1 to 10 centimeters, but is not limited to this. The height of the structure 200A is the same as the height of the interior of the greenhouse 10 at the position where the structure 200A is installed. The width of the structure 200A is the same as the width of the interior of the greenhouse 10.

[0127] The front wall 210 is a component that can change its form. Therefore, the structure 200A is a variable structure. The structure 200A may further include a floor material (not shown). The floor material is in contact with the front wall 210 and the vertical wall V. The floor material is laid on the floor F of the inner side I4 (all or part of the floor F of the inner side I4). The opening 251 may be provided in the floor material. The opening 252 may be provided in the floor material. The inner side I4 is formed by being surrounded by the floor material in addition to the front wall 210, the ceiling C, and the vertical wall V.

[0128] (3) Modifications The following description of modifications of the second embodiment will focus on the differences from the second embodiment, omitting the description of the similarities to the second embodiment.

[0129] (3-1) Variation 2A The structure 200A and the structure 200B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0130] (3-2) Modification 2B The configuration of the front wall 210 of the second embodiment and modification 2A may be changed by the control of a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by the control of the control device.

[0131] <Third Embodiment> (1) Overall Configuration The overall configuration of the facility 3 according to the third embodiment will be described. Hereinafter, similarities between the first and third embodiments will be omitted, and differences between the first and third embodiments will be mainly described. Fig. 24 is a schematic diagram showing the overall configuration of the facility 3 according to the third embodiment. The facility 3 mainly includes a greenhouse 10 and an air conditioner 11.

[0132] (1-1) Greenhouse The greenhouse 10 is mainly equipped with a structure 300A and a structure 300B. The interior of the greenhouse 10 is divided into an inside I7 of the structure 300A, an inside I8 of the structure 300B, and a space I9. The space I9 is ​​outside the structures 300A and 300B and is inside the greenhouse 10. Details of the structures 300A and 300B will be described later.

[0133] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I7 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I8 via a hose (not shown) that is different from the hose that communicates with the inside I7. The hose that communicates with the air outlet of the air conditioner 11 and the inside I7 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I8 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I7 and the inside I8 via the hoses.

[0134] (2) Detailed Configuration The detailed configuration of the structure 300A and the structure 300B will be described. The structure 300A is a variable structure whose configuration can be changed by the operation of the structure 300A. The structure 300B is a variable structure whose configuration can be changed by the operation of the structure 300B. The structures of the structure 300A and the structure 300B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 300A is similar to the function of the structure 300B. The structure and function of the structure 300A will be described below.

[0135] Fig. 25 is a perspective view showing the detailed configuration of the structure 300A. Fig. 26 is a front view showing the detailed configuration of the structure 300A. Fig. 27 is a rear view showing the detailed configuration of the structure 300A. Fig. 28 is a left side view showing the detailed configuration of the structure 300A. Fig. 29 is a right side view showing the detailed configuration of the structure 300A. Fig. 30 is a plan view showing the detailed configuration of the structure 300A.

[0136] The structure 300A mainly includes a front wall 310, a third guide rail 311, a fourth guide rail 312, a case 313, and a right side wall 330. The third guide rail 311 and the fourth guide rail 312 face each other.

[0137] The front wall 310 is mainly composed of a plurality of slats SL and an upper plate 314. For example, the front wall 310 is mainly composed of 14 slats SL and the upper plate 314. The slats SL are connected to adjacent slats SL. The slats SL are approximately perpendicular to the floor F. The slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and can slide in the Z direction or the negative Z direction (the direction in which the third guide rail 311 and the fourth guide rail 312 extend). The configuration of the front wall 310 can be changed by the slats SL sliding while being guided by the third guide rail 311 and the fourth guide rail 312.

[0138] The lower end of the upper plate 314 contacts the fourth guide rail 312. The upper end of the upper plate 314 contacts the ceiling C. The left end of the upper plate 314 contacts the vertical wall V. The right end of the upper plate 314 contacts the right wall 330.

[0139] An opening 351 that communicates with a hose (not shown) is provided in the upper plate 314. The opening 351 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I7 through the opening 351. The opening 351 may be provided in the slat SL or the right side wall 330. The opening 351 may be provided to the right of approximately the center of the structure 300A in the Z direction.

[0140] The front wall 310 faces the aisle 102. The case 313 is provided on the right side of the front wall 310 and behind the third guide rail 311 and the fourth guide rail 312. The case 313 houses the slats SL that are slid in the Z direction. The case 313 is provided so as to be able to house all of the slats SL that constitute the front wall 310. The case 313 may also be provided on the left side of the front wall 310.

[0141] The right side wall 330 is in contact with the front wall 310, the ceiling C, and the vertical wall V. The right side wall 330 is an example of a first component. An opening 352 that communicates with the outside of the structure 300A is provided in the right side wall 330. The opening 352 is an example of an exhaust port.

[0142] The air on the inside I7 is discharged from the inside I7 to the outside of the structure 300A through the opening 352. For example, the opening 352 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 352 is an example of a second hose. The air on the inside I7 flows to the air intake of the air conditioner 11 via the opening 352 and the hose.

[0143] The opening 352 may be provided in the front wall 310. The opening 352 may be provided forward of approximately the center of the structure 300A in the X direction. The opening 352 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air intake of the air conditioner 11.

[0144] The area of ​​the floor F where the plant P is grown is surrounded by the front wall 310, the right side wall 330, the ceiling C, and the vertical wall V, thereby forming an inside I7. Specifically, the front wall 310 surrounds the front side of the area of ​​the floor F where the plant P is grown. The vertical wall V surrounds the left side of the area of ​​the floor F where the plant P is grown. The right side wall 330 surrounds the right side of the area of ​​the floor F where the plant P is grown. The vertical wall V surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling C surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0145] The inside I7 is isolated from the outside of the structure 300A and the passage 102 by the front wall 310, the right side wall 330, the ceiling C, and the vertical wall V. The space between the inside I7, the outside of the structure 300A, and the passage 102 is covered by the front wall 310, the right side wall 330, the ceiling C, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 300A and the passage 102 to the inside I7. Therefore, air supplied to the inside I7 through the opening 351 is unlikely to flow from the inside I7 to the outside of the structure 300A. Air in the space I9 is ​​also unlikely to flow to the inside I7. It is difficult for people or equipment to approach the inside I7. People or equipment cannot secure a working space.

[0146] Plants P are grown in the inner part I7. A part or all of the floor F in the inner part I7 is filled with soil (not shown) in which the plants P can be planted or with a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I7, the plants P are planted in soil or immersed in the nutrient solution.

[0147] Examples of the configuration of the right side wall 330 and the slat SL include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0148] The front wall 310 (14 slats SL) and the right side wall 330 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I9 can be transmitted to the interior I7. Because the front wall 310 (14 slats SL) and the right side wall 330 are transparent or semi-transparent, the plants P on the interior I7 can be seen through from the outside of the structure 300A. Note that the case 313 does not have to include transparent or semi-transparent vinyl, glass, or plastic film.

[0149] The depth of the structure 300A is a value that ensures D10, which is the shortest distance in the X direction from the plant P to the front wall 310 when the plant P has finished growing. D10 is preferably, but not limited to, 1 to 10 centimeters.

[0150] The height of the structure 300A is the same as the height of the interior of the greenhouse 10 at the position where the structure 300A is installed. The width of the structure 300A is a value that ensures D11. D11 is the shortest distance in the Z direction from the plant P to the right side wall 330 when the plant P has finished growing. D11 is preferably, but not limited to, 1 to 10 centimeters.

[0151] The structure 300A may further include a flooring material (not shown). The flooring material is in contact with the front wall 310, the vertical wall V, and the right side wall 330. The flooring material is laid on the floor F of the inner side I7 (all or part of the floor F of the inner side I7). The opening 351 may be provided in the flooring material. The opening 352 may be provided in the flooring material. The inner side I7 is formed by being surrounded by the flooring material in addition to the front wall 310, the right side wall 330, the ceiling C, and the vertical wall V.

[0152] The right side wall 330 is a component that cannot be changed in shape. The front wall 310 is a component that can be changed in shape. Therefore, the structure 300A is a variable structure. Note that the right side wall 330 may be a component that can be changed in shape. Various aspects of the structure 300A will be described below.

[0153] Fig. 31 is a perspective view showing a detailed configuration of the structure 300A. The state of Fig. 31 is a state in which the slat SL is slid in the Z direction from the states of Figs. 25, 26, 27, 28, 29, and 30.

[0154] Of the 14 slats SL, seven slats SL are housed in a case 313. The outside of the structure 300A, the passage 102, and the inside I7 are in communication with each other through the front side of the structure 300A. By changing the configuration of the front wall 310, the state in which the outside of the structure 300A, the passage 102, and the inside I7 were blocked off has been changed to a state in which the outside of the structure 300A, the passage 102, and the inside I7 are in communication with each other. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P through the front side of the structure 300A.

[0155] Figure 32 is a perspective view showing the detailed configuration of the structure 300A. The state of Figure 32 is an embodiment in which the slats SL have been slid in the Z direction from the state of Figure 31. The fourteen slats SL are housed in a case 313. The outside of the structure 300A and the passage 102 communicate with the inside I7 via the front side of the structure 300A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 300A.

[0156] The state in Fig. 31 is also a state in which the slat SL has been slid in the minus Z direction from the state in Fig. 32. The states in Figs. 25, 26, 27, 28, 29, and 30 are also states in which the slat SL has been slid in the minus Z direction from the state in Fig. 31. By changing the state of the front wall 310, the state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 is changed to a state in which the outside of the structure 300A and the passage 102 are connected to the inside I7 is blocked.

[0157] (3) Operation The operation of the equipment 3 when a person or device performs harvesting work will be described. Since the operation of the structure 300A and the operation of the structure 300B are similar, the operation of the structure 300A will be mainly described. Figure 33 is a flowchart showing the operation of the equipment 3. Air heated by the air conditioner 11 is supplied to the inside I7 through the hose and the opening 351. The structure 300A has the configurations shown in Figures 25, 26, 27, 28, 29, and 30.

[0158] Fourteen slats SL cover the front side of the structure 300A, isolating the outside of the structure 300A and the passage 102 from the inside I7. The heated air supplied to the inside I7 does not easily flow to the outside of the structure 300A. The temperature of the inside I7 is maintained higher than the temperature of the space I9. Therefore, the inside I7 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting. No working space is provided.

[0159] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 300A. The person or device applies a force in the Z direction to one or more of the 14 slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and slide in the Z direction (step S11).

[0160] As the slats SL slide in the Z direction, the rightmost slat SL of the 14 slats SL is stored in the case 313. When the seven slats SL are stored in the case 313, the state of the structure 300A is changed to the state shown in Fig. 31 (step S12). A person or a device continues to apply a force in the Z direction to one or more slats SL.

[0161] As the slats SL slide in the Z direction, the 14 slats SL are stored in the case 313. The state of the structure 300A is changed to the state shown in FIG. 32 (step S13). The front side of the structure 300A connects the outside of the structure 300A and the passage 102 with the inside I7. Now that a working space has been secured, a person or a device can perform harvesting work on the plants P. The person or a device begins harvesting work on the plants P.

[0162] When the harvesting work is completed, a person or device applies a force in the negative Z direction to one or more slats SL stored in the case 313. Because the slats SL are connected to adjacent slats SL, the force in the negative Z direction is transmitted to the 14 slats SL. Therefore, the 14 slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and slide in the negative Z direction (step S14).

[0163] The slats SL are pulled out to the left of the case 313. When the seven slats SL are pulled out to the left from the case 313, the state of the structure 300A is changed to the state shown in Fig. 31 (step S15). A person or device continues to apply a force in the negative Z direction to one or more slats SL. The fourteen slats SL are guided by the third guide rail 311 and the fourth guide rail 312 and slide in the negative Z direction.

[0164] When the 14 slats SL are pulled out to the left from the case 313, the structure 300A is transformed into the state shown in Figures 25, 26, 27, 28, 29, and 30 (step S16). The front side of the structure 300A is covered by the 14 slats SL. Therefore, the outside of the structure 300A and the passage 102 are separated from the inside 17. People or equipment can move to the outside of the greenhouse 10 through the passage 102 and the entrance / exit 101.

[0165] (4) Modifications A modification of the third embodiment will be described, focusing on the differences from the third embodiment, and omitting the description of the similarities to the third embodiment.

[0166] (4-1) Modification 3A The facility 3 may include, instead of the structures 300A and 300B, a structure (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the structures 300A and 300B. The structure 300A has, instead of the right side wall 330, a left side wall (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the right side wall 330.

[0167] (4-2) Variation 3B In the third embodiment or variation 3A, the structure 300A and the structure 300B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0168] (4-3) Modification 3C The front wall 310 of the third embodiment, Modification 3A, and Modification 3B may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 311 and the fourth guide rail 312 by the control device.

[0169] (5) The variable-feature structure further includes a first component in contact with the front wall 310. The first component is the right side wall 330 or the left side wall in contact with the front wall 310. The insides I7 and I8 are formed by being surrounded by at least the front wall 310, the first component, and at least one of a vertical wall V of another structure and a ceiling C of another structure.

[0170] In addition to the front wall 310, the variable structure can separate the outside of the variable structure from the insides I7 and I8 by the right wall 330 or the left wall. Therefore, the variable structure can further reduce the scope of air conditioning. The variable structure can achieve energy savings in the cultivation of plants P, etc., and reduce the costs associated with the cultivation of plants P, etc.

[0171] When other structures are subjected to an external force, the external force is dispersed to the right wall 330 or the left wall in addition to the front wall 310. Therefore, the variable structure can protect other structures and plants P, etc., from physical external forces.

[0172] <Fourth embodiment> (1) Overall configuration The overall configuration of the facility 4 according to the fourth embodiment will be described. Hereinafter, similarities between the second and fourth embodiments will be omitted, and differences between the second and fourth embodiments will be mainly described. Fig. 34 is a schematic diagram showing the overall configuration of the facility 4 according to the fourth embodiment. The facility 4 mainly includes a greenhouse 10 and an air conditioner 11.

[0173] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 400A and a structure 400B. The interior of the green house 10 is divided into an inside I10 of the structure 400A, an inside I11 of the structure 400B, and a space I12. The space I12 is outside the structures 400A and 400B and is inside the green house 10. Details of the structure 400A and the structure 400B will be described later.

[0174] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I10 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I11 via a hose (not shown) that is different from the hose that communicates with the inside I10. The hose that communicates with the air outlet of the air conditioner 11 and the inside I10 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I11 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I10 and the inside I11 via the hoses.

[0175] (2) Detailed Configuration The detailed configuration of the structure 400A and the structure 400B will be described. The structure 400A is a variable structure whose configuration can be changed by the operation of the structure 400A. The structure 400B is a variable structure whose configuration can be changed by the operation of the structure 400B. The structures of the structure 400A and the structure 400B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 400A and the structure 400B are similar. The structure and function of the structure 400A will be described below.

[0176] Fig. 35 is a perspective view showing the detailed configuration of the structure 400A. Fig. 36 is a front view showing the detailed configuration of the structure 400A. Fig. 37 is a rear view showing the detailed configuration of the structure 400A. Fig. 38 is a left side view showing the detailed configuration of the structure 400A. Fig. 39 is a right side view showing the detailed configuration of the structure 400A. Fig. 40 is a plan view showing the detailed configuration of the structure 400A.

[0177] The structure 400A mainly has a front wall 210, a third guide rail 111, a fourth guide rail 112, and a rear wall 440. The structures and functions of the third guide rail 111 and the fourth guide rail 112 are the same as those in the second embodiment, and therefore descriptions thereof will be omitted. The structure and functions of the front wall 210, other than the openings 451 and 452, are the same as those in the second embodiment, and therefore descriptions thereof will be omitted.

[0178] The rear wall 440 faces the front wall 210 and is in contact with the ceiling C and the vertical wall V. The rear wall 440 is provided with an opening 451 that communicates with a hose (not shown). The rear wall 440 also is provided with an opening 452 that communicates with the outside of the structure 400A.

[0179] The opening 451 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I10 through the opening 451. The opening 451 is provided vertically below the approximate center of the structure 400A in the Y direction. The opening 451 may also be provided in the front wall 210. The opening 451 may also be provided to the right of the approximate center of the structure 400A in the Z direction. The opening 451 may also be provided vertically above the approximate center of the structure 400A in the Y direction.

[0180] The opening 452 is an example of an exhaust port and is provided vertically above the center of the structure 400A in the Y direction.

[0181] The air inside the inside I10 is discharged from the inside I10 to the outside of the structure 400A through the opening 452. For example, the opening 452 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 452 is an example of a second hose. The air inside the inside I10 flows into the air intake of the air conditioner 11 via the opening 452 and the hose.

[0182] The opening 452 may be provided in the front wall 210. The opening 452 may be provided to the left of approximately the center of the structure 400A in the Z direction. The opening 452 may be provided vertically below approximately the center of the structure 400A in the Y direction. The opening 452 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0183] The interior I10 is formed by surrounding the area of ​​the floor F where the plant P is grown with the front wall 210, the rear wall 440, the ceiling C, and the vertical wall V. Specifically, the front wall 210 surrounds the front side of the area of ​​the floor F where the plant P is grown. The vertical wall V surrounds the left and right sides of the area of ​​the floor F where the plant P is grown. The rear wall 440 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling C surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0184] The inside I10 is isolated from the outside of the structure 400A and the passage 102 by the front wall 210, the rear wall 440, the ceiling C, and the vertical wall V. The space between the inside I10, the outside of the structure 400A, and the passage 102 is covered by the front wall 210, the rear wall 440, the ceiling C, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 400A and the passage 102 to the inside I10. Therefore, air supplied to the inside I10 through the opening 451 is unlikely to flow from the inside I10 to the outside of the structure 400A. Air in the space I12 is also unlikely to flow to the inside I10. It is difficult for people or equipment to approach the inside I10. People or equipment cannot secure a working space.

[0185] Plants P are grown in the inner part I10. A part of the floor F in the inner part I10 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I10, the plants P are planted in soil or immersed in the nutrient solution.

[0186] Examples of the configuration of the rear wall 440 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0187] The rear wall 440 includes a transparent or semi-transparent vinyl, glass, or plastic film so that light from the illumination of the space I12 can be transmitted to the interior I10. Because the rear wall 440 is transparent or semi-transparent, the plants P on the interior I10 can be seen through from the outside of the structure 400A.

[0188] The structure 400A is provided so as to ensure D12 and D13. D12 is the shortest distance in the X direction from the plant P to the front wall 210 when the plant P has finished growing. D12 is preferably, but not limited to, 1 to 10 centimeters. D13 is the shortest distance in the X direction from the plant P to the rear wall 440 when the plant P has finished growing. D13 is preferably, but not limited to, 1 to 10 centimeters.

[0189] The height of the front wall 210 is the same as the height of the interior of the greenhouse 10 at the position where the front wall 210 is provided. The height of the rear wall 440 is the same as the height of the interior of the greenhouse 10 at the position where the rear wall 440 is provided. The width of the structure 400A is the same as the width of the interior of the greenhouse 10.

[0190] The front wall 210 is a component that can change its shape. Therefore, the structure 400A is a variable structure. The structure 400A may further include a floor material (not shown). The floor material is in contact with the front wall 210, the rear wall 440, and the vertical wall V. The floor material is laid on the floor F of the inner side I10 (all or part of the floor F of the inner side I10). The opening 451 may be provided in the floor material. The opening 452 may be provided in the floor material. The inner side I10 is formed by being surrounded by the floor material in addition to the front wall 210, the rear wall 440, the ceiling C, and the vertical wall V.

[0191] (3) Modifications A modification of the fourth embodiment will be described, focusing on the differences from the fourth embodiment, and omitting the description of the similarities to the fourth embodiment.

[0192] (3-1) Variation 4A The structure 400A and the structure 400B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0193] (3-2) Modification 4B The front wall 210 of the fourth embodiment, modification 4A, may be changed in appearance by control of a control device (not shown). In other words, the slat SL may be slid along the third guide rail 111 and the fourth guide rail 112 by control of the control device.

[0194] (4) Features (4-1) The variable structure further includes a rear wall 440 erected inside and facing the front wall 210. The inside I10 and the inside I11 are formed by being surrounded by at least the front wall 210, the rear wall 440, and at least one of a vertical wall V of another structure and a ceiling C of another structure.

[0195] In addition to the front wall 210, the variable structure can separate the outside of the variable structure from the insides I10 and I11 by the rear wall 440. This allows the variable structure to further reduce the scope of air conditioning. The variable structure can achieve energy savings in the cultivation of plants P, etc., and reduce the costs associated with the cultivation of plants P, etc.

[0196] When other structures are subjected to an external force, the external force is dispersed not only to the front wall 210 but also to the rear wall 440. Therefore, the variable structure can protect other structures and plants P, etc., from physical external forces.

[0197] (4-2) The supply port of the variable structure is located approximately vertically below the center of the variable structure in the vertical direction. To create an environment suitable for growing plants, the space where the plants are located may be heated or humidified. Heated air is lighter than unheated air, so it moves from bottom to top. Humidified air is also lighter than unhumidified air, so it moves from bottom to top.

[0198] The variable structure has a supply unit located approximately vertically below the approximate vertical center of the variable structure. When heated air or humidified air is supplied to the supply unit, the heated air or humidified air moves from approximately vertically below to approximately vertically above. The variable structure creates airflow on the insides I10 and I11, making it less likely that temperature or humidity variations will occur on the insides I10 and I11. Therefore, the variable structure makes the insides I10 and I11 an environment more suitable for growing plants P, etc.

[0199] (4-3) When the supply port of the variable structure is provided substantially vertically below the center of the variable structure in the vertical direction, the exhaust port is provided substantially vertically above the center of the variable structure in the vertical direction.

[0200] The variable structure creates airflow on the insides I10 and I11, making it difficult for temperature or humidity variations to occur on the insides I10 and I11. As a result, the variable structure makes the insides I10 and I11 an environment more suitable for growing plants P, etc.

[0201] <Fifth Embodiment> (1) Overall Configuration The overall configuration of the facility 5 according to the fifth embodiment will be described. Hereinafter, similarities between the first and fifth embodiments will be omitted, and the following description will focus on differences between the first and fifth embodiments. Fig. 41 is a schematic diagram showing the overall configuration of the facility 5 according to the fifth embodiment. The facility 5 mainly includes a greenhouse 10 and an air conditioner 11.

[0202] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 500A and a structure 500B. The interior of the green house 10 is divided into an inside I13 of the structure 500A, an inside I14 of the structure 500B, and a space I15. The space I15 is outside the structures 500A and 500B and is inside the green house 10. Details of the structure 500A and the structure 500B will be described later.

[0203] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I13 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I14 via a hose (not shown) that is different from the hose that communicates with the inside I13. The hose that communicates with the air outlet of the air conditioner 11 and the inside I13, and the hose that communicates with the air outlet of the air conditioner 11 and the inside I14 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I13 and the inside I14 via the hoses.

[0204] (2) Detailed Configuration The detailed configuration of the structure 500A and the structure 500B will be described. The structure 500A is a variable structure that can change the state of the structure 500A by operating the structure 500A. The structure 500B is a variable structure that can change the state of the structure 500B by operating the structure 500B. The structures of the structure 500A and the structure 500B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 500A and the structure 500B are similar. The structure and function of the structure 500A will be described below.

[0205] Fig. 42 is a perspective view showing the detailed configuration of the structure 500A. Fig. 43 is a front view showing the detailed configuration of the structure 500A. Fig. 44 is a rear view showing the detailed configuration of the structure 500A. Fig. 45 is a left side view showing the detailed configuration of the structure 500A. Fig. 46 is a right side view showing the detailed configuration of the structure 500A. Fig. 47 is a plan view showing the detailed configuration of the structure 500A.

[0206] The structure 500A mainly has a front wall 510, a rear wall 540, a ceiling 550, and a rotation axis AX. The front wall 510 faces the aisle 102. The upper end of the front wall 510 is connected to the front end of the ceiling 550.

[0207] The rear wall 540 faces the front wall 510 and is in contact with the vertical wall V and the ceiling 550. An opening 551 and an opening 552 are provided in the rear wall 540. The opening 551 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I13 through the opening 551. The opening 551 is provided approximately vertically above the approximate vertical center of the structure 500A.

[0208] The opening 551 may be provided in the front wall 510 or the ceiling 550. The opening 551 may be provided substantially vertically below the substantially vertical center of the structure 500A. The opening 551 may be provided to the right of the substantially Z-direction center of the structure 500A.

[0209] The opening 552 is an example of an exhaust port and is provided substantially vertically below the center of the structure 500A in the vertical direction.

[0210] The air in the inside I13 is discharged from the inside I13 to the outside of the structure 500A through the opening 552. For example, the opening 552 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 552 is an example of a second hose. The air in the inside I13 flows to the air intake of the air conditioner 11 via the opening 552 and the hose.

[0211] The opening 552 may be provided in the front wall 510 or the ceiling 550. The opening 552 may be provided substantially vertically above the substantially vertical center of the structure 500A. The opening 552 may be provided to the left of the substantially Z-direction center of the structure 500A. The opening 552 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0212] The rotation axis AX is provided along the rear end of the ceiling 550. The ceiling 550 faces the floor F and is in contact with the front wall 510, the rear wall 540, and the vertical wall V. The ceiling 550 is an example of a first component. The ceiling 550 can be moved by rotating about the rotation axis AX. The ceiling 550 is provided to be rotatable in a plane extending in the X and Y directions with the rotation axis AX as the rotation center. The front end of the ceiling 550 is connected to the upper end of the front wall 510. Therefore, when the ceiling 550 is rotated about the rotation axis AX, the front wall 510 also rotates along with the ceiling 550. This changes the configuration of the front wall 510.

[0213] The area of ​​the floor F where the plant P is grown is surrounded by a front wall 510, a rear wall 540, a ceiling 550, and a vertical wall V, thereby forming an inside I13. Specifically, the front wall 510 surrounds the front side of the area of ​​the floor F where the plant P is grown. The vertical walls V surround the left and right sides of the area of ​​the floor F where the plant P is grown. The rear wall 440 surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 550 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0214] The inside I13 is isolated from the outside of the structure 500A and the passage 102 by the front wall 510, the rear wall 540, the ceiling 550, and the vertical wall V. The space between the inside I13, the outside of the structure 500A, and the passage 102 is covered by the front wall 510, the rear wall 540, the ceiling 550, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 500A and the passage 102 to the inside I13. Therefore, air supplied to the inside I13 through the opening 551 is unlikely to flow from the inside I13 to the outside of the structure 500A. Air in the space I15 is also unlikely to flow to the inside I13. It is difficult for people or equipment to approach the inside I13. People or equipment cannot secure a working space.

[0215] Plants P are grown in the inner side I13. A part of the bed F in the inner side I13 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I13, the plants P are planted in soil or immersed in the nutrient solution.

[0216] Examples of the configuration of the front wall 510, the rear wall 540, and the ceiling 550 include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0217] The front wall 510, the rear wall 540, and the ceiling 550 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I15 is transmitted to the interior I13. Because the front wall 510, the rear wall 540, and the ceiling 550 are transparent or semi-transparent, the plants P on the interior I13 can be seen through from the outside of the structure 500A.

[0218] The depth of the structure 500A is a value that ensures D14 and D15. D14 is the shortest distance in the X direction from the plant P to the front wall 510 when the plant P has finished growing. D14 is preferably 1 to 10 centimeters, but is not limited to this. D15 is the shortest distance in the negative X direction from the plant P to the rear wall 540 when the plant P has finished growing. D15 is preferably 1 to 10 centimeters, but is not limited to this.

[0219] The height of the structure 500A is a value that ensures D16. D16 is the shortest distance in the Y direction from the plant P to the ceiling 550 when the plant P has finished growing. D16 is preferably, but not limited to, 1 to 10 centimeters. The width of the structure 500A is the same as the width of the interior of the greenhouse 10.

[0220] The rear wall 540 is a component that cannot be changed in shape. The front wall 510 and the ceiling 550 are components that can be changed in shape. Therefore, the structure 500A is a variable structure. Below, aspects of the structure 500A that differ from the aspects of the structure 500A in Figures 42, 43, 44, 45, 46, and 47 will be described. Figure 48 is a perspective view showing the detailed configuration of the structure 500A.

[0221] The state in Figure 48 is a state in which the ceiling 550 has been rotated about the rotation axis AX from the states in Figures 42, 43, 44, 45, 46, and 47. The ceiling 550 has been rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. As the ceiling 550 has been rotated, the front wall 510 has also been rotated along with the ceiling 550.

[0222] The inside I13 of the structure 500A is in a state of communication with the outside of the structure 500A and the passage 102 via the front and upper sides. By changing the configuration of the ceiling 550 and the front wall 510, the state in which the outside of the structure 500A and the passage 102 were isolated from the inside I13 has been changed to a state in which the outside of the structure 500A and the passage 102 are in communication with the inside I13. Because a work space has been secured, a person or device performing agricultural work can perform agricultural work on plants P via the front and upper sides of the structure 500A.

[0223] 42, 43, 44, 45, 46, and 47 are also modes in which the ceiling 550 is rotated about the rotation axis AX from the mode in Fig. 48. The ceiling 550 is rotated slightly less than 90 degrees on a plane extending in the X and Y directions with the rotation axis AX as the rotation center. Since the ceiling 550 is rotated, the front wall 510 is also rotated along with the ceiling 550.

[0224] By changing the configuration of the ceiling 550 and the front wall 510, the state in which the outside of the structure 500A and the passage 102 are connected to the inside I13 has been changed to a state in which the outside of the structure 500A and the passage 102 are blocked from the inside I13.

[0225] (3) Operation The operation of the equipment 5 when a person or device performs harvesting work will be described. Since the operation of the structure 500A and the operation of the structure 500B are similar, the operation of the structure 500A will be mainly described. Figure 49 is a flowchart showing the operation of the equipment 5. Air heated by the air conditioner 11 is supplied to the inside I13 through the hose and the opening 551. The structure 500A has the configurations shown in Figures 42, 43, 44, 45, 46, and 47.

[0226] A front wall 510 covers the front side of the structure 500A, and a ceiling 550 covers the upper side of the structure 500A. Therefore, the outside of the structure 500A and the passage 102 are isolated from the inside I13. The heated air supplied to the inside I13 does not easily flow to the outside of the structure 500A. The temperature of the inside I13 is maintained higher than the temperature of the space I15. Therefore, the inside I13 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting.

[0227] A person or device moves from the outside of the greenhouse 10 into the inside of the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 on the front side of the structure 500A. The person or device applies a force in the Y direction and the minus X direction to at least one of the front wall 510 and the ceiling 550. The ceiling 550 receives the forces in the Y direction and the minus X direction and is rotated about the rotation axis AX. Specifically, the ceiling 550 rotates in a plane extending in the X direction and the Y direction with the rotation axis AX as the rotation center. The front wall 510 connected to the ceiling 550 also rotates together with the ceiling 550 (step S21).

[0228] The ceiling 550 is rotated slightly less than 90 degrees on a plane extending in the X and Y directions around the rotation axis AX as the center of rotation. The configuration of the structure 500A is changed to the configuration shown in Fig. 48 (step S22).

[0229] The front and top sides of the structure 500A allow the outside of the structure 500A and the passage 102 to communicate with the inside 113. Now that the work space has been secured, a person or a device can begin harvesting the plants P. The person or the device begins harvesting the plants P.

[0230] When the harvesting work is completed, a person or a device applies a force in the negative Y direction and the X direction to at least one of the front wall 510 and the ceiling 550. The ceiling 550 receives the forces in the negative Y direction and the X direction and is rotated about the rotation axis AX. Specifically, the ceiling 550 is rotated in a plane extending in the X direction and the Y direction with the rotation axis AX as the rotation center. Furthermore, the front wall 510 connected to the ceiling 550 is also rotated together with the ceiling 550 (step S23).

[0231] The ceiling 550 is rotated slightly less than 90 degrees on a plane extending in the X and Y directions, with the rotation axis AX as the center of rotation. The ceiling 550 covers the upper side of the structure 500A. The front wall 510 covers the front side of the structure 500A. The configuration of the structure 500A is changed to the configurations shown in Figures 42, 43, 44, 45, 46, and 47 (step S24). The outside and passage 102 of the structure 500A are isolated from the inside I13.

[0232] (4) Modifications A modification of the fifth embodiment will be described, focusing on the differences from the fifth embodiment, and omitting the description of the similarities to the fifth embodiment.

[0233] (4-1) Variation 5A The structure 500A and the structure 500B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0234] (4-2) Modification 5B The front wall 510 and the ceiling 550 of the fifth embodiment and modification 5A may be changed in appearance under the control of a control device (not shown). In other words, the front wall 510 and the ceiling 550 may be rotated around the rotation axis AX under the control of the control device.

[0235] (5) Features (5-1) The variable structure further includes a movable ceiling 550 that faces the interior floor F and is connected to the front wall 510, and a rotation axis AX that is provided along the edge of the ceiling 550. When the ceiling 550 is rotated about the rotation axis AX, the front wall 510 is also rotated along with the ceiling 550, thereby changing the state of the front wall 510. The insides I13 and I14 are formed by being surrounded by at least the front wall 510, the ceiling 550, and at least one of the vertical wall V of another structure and the ceiling C of another structure.

[0236] The front wall 510 rotates along with the ceiling 550. The force applied to the front wall 510 is less likely to be dispersed in unspecified directions. The front wall 510 is moved in a fixed direction by the rotation axis AX. Therefore, the variable structure allows the state of the front wall 510 to be easily changed by a person or a device.

[0237] (5-2) When the supply port of the variable structure is provided substantially vertically above the center of the variable structure in the vertical direction, the exhaust port is provided substantially vertically below the center of the variable structure in the vertical direction.

[0238] The variable structure creates airflow on the insides I13 and I14, making it difficult for temperature or humidity variations to occur on the insides I13 and I14. As a result, the variable structure makes the insides I13 and I14 an environment more suitable for growing plants P, etc.

[0239] <Sixth embodiment> (1) Overall configuration The overall configuration of the facility 6 according to the sixth embodiment will be described. Hereinafter, similarities between the first and sixth embodiments will be omitted, and differences between the first and sixth embodiments will be mainly described. Figure 50 is a schematic diagram showing the overall configuration of the facility 6 according to the sixth embodiment. The facility 6 mainly includes a greenhouse 10 and an air conditioner 11.

[0240] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 600A and a structure 600B. The interior of the green house 10 is divided into an inside I16 of the structure 600A, an inside I17 of the structure 600B, and a space I18. The space I18 is outside the structures 600A and 600B and is inside the green house 10. Details of the structure 600A and the structure 600B will be described later.

[0241] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I16 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I17 via a hose (not shown) that is different from the hose that communicates with the inside I16. The hose that communicates with the air outlet of the air conditioner 11 and the inside I16 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I17 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I16 and the inside I17 via the hoses.

[0242] (2) Detailed Configuration The detailed configuration of the structure 600A and the structure 600B will be described. The structure 600A is a variable structure whose configuration can be changed by the operation of the structure 600A. The structure 600B is a variable structure whose configuration can be changed by the operation of the structure 600B. A variable structure is a structure whose configuration can be changed. The structures of the structure 600A and the structure 600B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 600A is similar to the function of the structure 600B. The structure and function of the structure 600A will be described below.

[0243] Fig. 51 is a perspective view showing the detailed configuration of structure 600A. Fig. 52 is a front view showing the detailed configuration of structure 600A. Fig. 53 is a rear view showing the detailed configuration of structure 600A. Fig. 54 is a left side view showing the detailed configuration of structure 600A. Fig. 55 is a right side view showing the detailed configuration of structure 600A. Fig. 56 is a plan view showing the detailed configuration of structure 600A.

[0244] The structure 600A mainly has a front wall 610, a first guide rail 612, a second guide rail 613, a case 614, a left side wall 620, and a ceiling 650. The first guide rail 612 and the second guide rail 613 face each other.

[0245] The front wall 610 is mainly composed of a plurality of slats SL. For example, the front wall 610 is mainly composed of nine slats SL. The slats SL are approximately perpendicular to the floor F. The slats SL are connected to adjacent slats SL. The slats SL are guided by the first guide rail 612 and the second guide rail 613 and can slide in the Y direction or the negative Y direction (the direction in which the first guide rail 612 and the second guide rail 613 extend). The configuration of the front wall 610 can be changed by the slats SL sliding while being guided by the first guide rail 612 and the second guide rail 613.

[0246] The front wall 610 faces the aisle 102. The case 614 is provided on the upper side of the front wall 610 and behind the first guide rail 612 and the second guide rail 613. The case 614 houses the slats SL that are slid in the Y direction. The case 614 is provided so as to be able to house all of the slats SL that constitute the front wall 610. The case 614 may also be provided on the lower side of the front wall 610.

[0247] The left side wall 620 is in contact with the front wall 610, the ceiling 650, and the vertical wall V. The left side wall 620 is an example of a first component. An opening 651 that is connected to a hose is provided in the left side wall 620. The opening 651 is an example of a supply port. Air conditioned by the air conditioner 11 is supplied to the inside I16 through the opening 651. The opening 651 is provided approximately vertically below the approximate vertical center of the structure 600A.

[0248] The opening 651 may be provided in the front wall 610 or the ceiling 650. The opening 651 may be provided substantially vertically above the substantially vertical center of the structure 600A. The opening 651 may be provided forward of the substantially X-direction center of the structure 600A.

[0249] The ceiling 650 faces the floor F and is in contact with the front wall 610, the left side wall 620, and the vertical wall V. The ceiling 650 is an example of a first component. The ceiling 650 is provided with an opening 652 that communicates with the outside of the structure 600A. The opening 652 is an example of an exhaust port. The opening 652 is provided approximately vertically above the approximate vertical center of the structure 600A.

[0250] The air in the inside I16 is discharged from the inside I16 to the outside of the structure 600A through the opening 652. For example, the opening 652 is connected to a hose (not shown) that is connected to the air intake of the air conditioner 11. The hose that is connected to the opening 652 is an example of a second hose. The air in the inside I16 flows to the air intake of the air conditioner 11 via the opening 652 and the hose.

[0251] The opening 652 may be provided in the front wall 610 or the left side wall 620. The opening 652 may be provided substantially vertically below the substantially vertical center of the structure 600A. The opening 652 may be provided forward of the substantially X-direction center of the structure 600A. The opening 652 may be connected to a hose (not shown) that is connected to a location outside the greenhouse 10 other than the air inlet of the air conditioner 11.

[0252] The area of ​​the floor F where the plant P is grown is surrounded by a front wall 610, a left wall 620, a ceiling 650, and a vertical wall V, thereby forming an inside I16. Specifically, the front wall 610 surrounds the front side of the area of ​​the floor F where the plant P is grown. The left wall 620 surrounds the left side of the area of ​​the floor F where the plant P is grown. The vertical wall V surrounds the right side of the area of ​​the floor F where the plant P is grown. The vertical wall V surrounds the rear side of the area of ​​the floor F where the plant P is grown. The ceiling 650 surrounds the upper side of the area of ​​the floor F where the plant P is grown.

[0253] The inside I16 is isolated from the outside of the structure 600A and the passage 102 by the front wall 610, the left side wall 620, the ceiling 650, and the vertical wall V. The space between the inside I16, the outside of the structure 600A, and the passage 102 is covered by the front wall 610, the left side wall 620, the ceiling 650, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 600A and the passage 102 to the inside I16. Therefore, air supplied to the inside I16 through the opening 651 is unlikely to flow from the inside I16 to the outside of the structure 600A. Air in the space I18 is also unlikely to flow to the inside I16. It is difficult for people or equipment to approach the inside I16. People or equipment cannot secure a working space.

[0254] Plants P are grown in the inner side I16. A part or all of the floor F in the inner side I16 is filled with soil (not shown) in which the plants P can be planted or with a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I16, the plants P are planted in soil or immersed in the nutrient solution.

[0255] Examples of the configurations of the left side wall 620, the ceiling 650, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0256] The front wall 610 (nine slats SL), the left side wall 620, and the ceiling 650 include transparent or translucent vinyl, glass, or plastic film so that light from the lighting in the space I18 is transmitted to the interior I16. Because the front wall 610 (nine slats SL), the left side wall 620, and the ceiling 650 are transparent or translucent, the plants P on the interior I16 can be seen through from the outside of the structure 600A. Note that the case 614 does not have to include transparent or translucent vinyl, glass, or plastic film.

[0257] The depth of the structure 600A is a value that ensures D17. D17 is the shortest distance in the X direction from the plant P to the front wall 610 when the plant P has finished growing. D17 is preferably, but not limited to, 1 to 10 centimeters.

[0258] The height of the structure 600A is a value that ensures D18, which is the shortest distance in the Y direction from the plant P to the ceiling 650 when the plant P has finished growing. D18 is preferably, but not limited to, 1 to 10 centimeters.

[0259] The width of the structure 600A is a value that ensures D19, which is the shortest distance in the negative Z direction from the plant P to the left wall 620 when the plant P has finished growing. D19 is preferably, but not limited to, 1 to 10 centimeters.

[0260] The left side wall 620 and the ceiling 650 are components that cannot be changed in shape. The front wall 610 is a component that can be changed in shape. Therefore, the structure 600A is a variable structure. Note that at least one of the left side wall 620 and the ceiling 650 may be a component that can be changed in shape.

[0261] The structure 600A may further include a flooring material (not shown). The flooring material is in contact with the front wall 610, the vertical wall V, and the left side wall 620. The flooring material is laid on the floor F of the inner side I16 (all or part of the floor F of the inner side I16). The opening 651 may be provided in the flooring material. The opening 652 may be provided in the flooring material. The inner side I16 is formed by being surrounded by the flooring material in addition to the front wall 610, the left side wall 620, the ceiling 650, and the vertical wall V. Various aspects of the structure 600A will be described below.

[0262] Fig. 57 is a perspective view showing the detailed configuration of the structure 600A. The state of Fig. 57 is a state in which the slat SL is slid in the Y direction from the states of Figs. 51, 52, 53, 54, 55, and 56.

[0263] Of the nine slats SL, five slats SL are housed in a case 614. The front side of the structure 600A connects the outside of the structure 600A, the passage 102, and the inside I16. By changing the configuration of the front wall 610, the state in which the outside of the structure 600A, the passage 102, and the inside I16 were blocked off has been changed to a state in which the outside of the structure 600A, the passage 102, and the inside I16 are connected. Because a work space is secured, people or equipment can perform agricultural work on plants P through the front side of the structure 600A.

[0264] Figure 58 is a perspective view showing the detailed configuration of the structure 600A. The state of Figure 58 is an embodiment in which the slats SL have been slid in the Y direction from the state of Figure 57. The nine slats SL are housed in a case 614. The outside of the structure 600A and the passage 102 communicate with the inside I16 via the front side of the structure 600A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 600A.

[0265] The state in Fig. 57 is also a state in which the slat SL has been slid in the minus Y direction from the state in Fig. 58. The states in Figs. 51, 52, 53, 54, 55, and 56 are also states in which the slat SL has been slid in the minus Y direction from the state in Fig. 57. By changing the state of the front wall 610, the state in which the outside of the structure 600A and the passage 102 are connected to the inside I16 is changed to a state in which the outside of the structure 600A and the passage 102 are connected to the inside I16.

[0266] (3) Operation The operation of the equipment 6 when a person or device performs harvesting work will be described. Since the operation of the structure 600A and the operation of the structure 600B are similar, the operation of the structure 600A will be mainly described. Figure 59 is a flowchart showing the operation of the equipment 6. Air heated by the air conditioner 11 is supplied to the inside I16 through the hose and the opening 651. The structure 600A has the configurations shown in Figures 51, 52, 53, 54, 55, and 56.

[0267] The front wall 610 (nine slats SL) covers the front side of the structure 600A. Therefore, the outside of the structure 600A and the passage 102 are isolated from the inside I16. The heated air supplied to the inside I16 does not easily flow to the outside of the structure 600A. The temperature of the inside I16 is maintained higher than the temperature of the space I18. Therefore, the inside I16 is an environment suitable for growing plants P. The plants P are in a state suitable for harvesting (a state where they have finished growing). No working space is provided.

[0268] A person or device moves from outside the greenhouse 10 into the greenhouse 10 through the entrance / exit 101. The person or device moves into the passage 102 at the front of the structure 600A. The person or device applies a force in the Y direction to one or more slats SL. Because the slats SL are connected to adjacent slats SL, the force in the Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 612 and the second guide rail 613 and slide in the Y direction (step S31).

[0269] As the slats SL slide in the Y direction, the nine slats SL are stored in the case 614, starting with the uppermost slat SL. When the five slats SL are stored in the case 614, the state of the structure 600A is changed to the state of the structure 600A in Fig. 57 (step S32). A person or a device continues to apply a force in the Y direction to one or more slats SL.

[0270] As the slats SL slide in the Y direction, the nine slats SL are stored in the case 614. The state of the structure 600A is changed to the state shown in FIG. 58 (step S33). The front side of the structure 600A connects the outside of the structure 600A and the passage 102 with the inside I16. Now that a working space has been secured, a person or device can perform harvesting work on the plants P. The person or device begins harvesting work on the plants P.

[0271] When the harvesting work is completed, a person or device applies a force in the negative Y direction to one or more of the nine slats SL stored in the case 614. Because the slats SL are connected to adjacent slats SL, the force in the negative Y direction is transmitted to the nine slats SL. Therefore, the nine slats SL are guided by the first guide rail 612 and the second guide rail 613 and slide in the negative Y direction (step S34).

[0272] The slats SL are lowered below the case 614. When the four slats SL have been lowered from the case 614, the state of the structure 600A is changed to the state shown in Fig. 57 (step S35). A person or device then applies a force in the negative Y direction to one or more slats SL. The nine slats SL are guided by the first guide rail 612 and the second guide rail 613 and slide in the negative Y direction.

[0273] When the nine slats SL are lowered from the case 614, the structure 600A is changed to the state shown in Figures 51, 52, 53, 54, 55, and 56 (step S36). The front side of the structure 600A is covered by the nine slats SL. Therefore, the outside of the structure 600A and the passage 102 are blocked from the inside 116.

[0274] (4) Modifications A modification of the sixth embodiment will be described, focusing on the differences from the sixth embodiment, and omitting the description of the similarities to the sixth embodiment.

[0275] (4-1) Modification 6A Facility 6 may include, instead of structures 600A and 600B, a structure (not shown) that is approximately symmetrical with structures 600A and 600B with respect to a plane extending in the X and Y directions. Structure 600A has, instead of left side wall 620, a left side wall (not shown) that is approximately symmetrical with left side wall 620 with respect to a plane extending in the X and Y directions.

[0276] (4-2) Variation 6B In the sixth embodiment or variation 6A, the structure 600A and the structure 600B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0277] (4-3) Modification 6C The front wall 610 of the sixth embodiment, Modification 6A, and Modification 6B may be modified by a control device (not shown). In other words, the slat SL may slide along the first guide rail 612 and the second guide rail 613 by the control device.

[0278] <Seventh embodiment> (1) Overall configuration The overall configuration of the facility 7 according to the seventh embodiment will be described. Hereinafter, similarities between the fourth embodiment and the seventh embodiment will be omitted, and differences between the fourth embodiment and the seventh embodiment will be mainly described. Fig. 60 is a schematic diagram showing the overall configuration of the facility 7 according to the seventh embodiment. The facility 7 mainly includes a greenhouse 10 and an air conditioner 11.

[0279] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 700A and a structure 700B. The interior of the green house 10 is divided into an inside I19 of the structure 700A, an inside I20 of the structure 700B, and a space I21. The space I21 is outside the structures 700A and 700B and is inside the green house 10. Details of the structures 700A and 700B will be described later.

[0280] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I19 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I20 via a hose (not shown) that is different from the hose that communicates with the inside I19. The hose that communicates with the air outlet of the air conditioner 11 and the inside I19 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I20 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I19 and the inside I20 via the hoses.

[0281] (2) Detailed Configuration The detailed configuration of the structure 700A and the structure 700B will be described. The structure 700A is a variable structure that can change the state of the structure 700A by operating the structure 700A. The structure 700B is a variable structure that can change the state of the structure 700B by operating the structure 700B. The structures of the structure 700A and the structure 700B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 700A is similar to the function of the structure 700B. The structure and function of the structure 700A will be described below.

[0282] Fig. 61 is a perspective view showing the detailed configuration of structure 700A. Fig. 62 is a front view showing the detailed configuration of structure 700A. Fig. 63 is a rear view showing the detailed configuration of structure 700A. Fig. 64 is a left side view showing the detailed configuration of structure 700A. Fig. 65 is a right side view showing the detailed configuration of structure 700A. Fig. 66 is a plan view showing the detailed configuration of structure 700A.

[0283] The structure 700A mainly has a front wall 210, a third guide rail 111, a fourth guide rail 112, a rear wall 440, and a left side wall 720. The structures and functions of the front wall 210, the third guide rail 111, the fourth guide rail 112, and the rear wall 440 are the same as those in the fourth embodiment, and therefore will not be described here.

[0284] The left side wall 720 is in contact with the front wall 210, the rear wall 440, and the ceiling C. The left side wall 720 is an example of a first component. The opening 451 may be provided in the front wall 210 or the left side wall 720. The opening 452 may be provided in the front wall 210 or the left side wall 720.

[0285] An inside I19 is formed by surrounding the area of ​​the floor F where the plant P is grown with the front wall 210, the rear wall 440, the ceiling C, the vertical wall V, and the left side wall 720. Specifically, the left side wall 720 surrounds the left side of the area of ​​the floor F where the plant P is grown.

[0286] The inside I19 is isolated from the outside of the structure 700A and the passage 102 by the front wall 210, rear wall 440, ceiling C, vertical wall V, and left side wall 720. The front wall 210, rear wall 440, ceiling C, vertical wall V, and left side wall 720 provide a barrier between the inside I19 and the outside of the structure 700A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 700A and the passage 102 to the inside I19. Therefore, air supplied to the inside I19 through the opening 451 is unlikely to flow from the inside I19 to the outside of the structure 700A. Air in space I21 is also unlikely to flow to the inside I19. It is difficult for people or equipment to approach the inside I19. People or equipment cannot secure a working space.

[0287] Plants P are grown in the inner part I19. A part of the bed F in the inner part I19 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I19, the plants P are planted in soil or immersed in the nutrient solution.

[0288] Examples of the configuration of the left side wall 720 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0289] The left side wall 720 includes a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I21 can be transmitted to the inside I19. Because the left side wall 720 is transparent or semi-transparent, the plants P on the inside I19 can be seen through from the outside of the structure 700A.

[0290] The width of the structure 700A is a value that ensures D20, which is the shortest distance in the negative Z direction from the plant P to the left wall 720 when the plant P has finished growing. D20 is preferably, but not limited to, 1 to 10 centimeters.

[0291] The front wall 210 is a component whose shape can be changed. Therefore, the structure 700A is a variable structure. The structure 700A may further include a floor material (not shown). The floor material is in contact with the front wall 210, the rear wall 440, the vertical wall V, and the left side wall 720. The floor material is laid on the floor F of the inner side I19 (all or part of the floor F of the inner side I19). The opening 451 may be provided in the floor material. The opening 452 may be provided in the floor material. The inner side I19 is formed by being surrounded by the floor material in addition to the front wall 210, the rear wall 440, the ceiling C, the vertical wall V, and the left side wall 720.

[0292] (3) Modifications A modification of the seventh embodiment will be described, focusing on the differences from the seventh embodiment, and omitting the description of the similarities to the seventh embodiment.

[0293] (3-1) Modification 7A The facility 7 may include, instead of the structures 700A and 700B, a structure (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the structures 700A and 700B. Instead of the left side wall 720, the structure 700A has a right side wall (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the left side wall 720.

[0294] (3-2) Variation 7B In the seventh embodiment or variation 7A, the structure 700A and the structure 700B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0295] (3-3) Modification 7C The front wall 210 of the seventh embodiment, Modification 7A, and Modification 7B may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by the control device.

[0296] <Eighth Embodiment> (1) Overall Configuration The overall configuration of the facility 8 according to the eighth embodiment will be described. Hereinafter, similarities between the first and eighth embodiments will be omitted, and the following description will focus on differences between the first and eighth embodiments. Figure 67 is a schematic diagram showing the overall configuration of the facility 8 according to the eighth embodiment. The facility 8 mainly includes a greenhouse 10 and an air conditioner 11.

[0297] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 800A and a structure 800B. The interior of the green house 10 is divided into an inside I22 of the structure 800A, an inside I23 of the structure 800B, and a space I24. The space I24 is outside the structures 800A and 800B and is inside the green house 10. Details of the structure 800A and the structure 800B will be described later.

[0298] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I22 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I23 via a hose (not shown) that is different from the hose that communicates with the inside I22. The hose that communicates with the air outlet of the air conditioner 11 and the inside I22 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I23 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I22 and the inside I23 via the hoses.

[0299] (2) Detailed Configuration The detailed configuration of the structure 800A and the structure 800B will be described. The structure 800A is a variable structure whose configuration can be changed by the operation of the structure 800A. The structure 800B is a variable structure whose configuration can be changed by the operation of the structure 800B. The structures of the structure 800A and the structure 800B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 800A is similar to the function of the structure 800B. The structure and function of the structure 800A will be described below.

[0300] Fig. 68 is a perspective view showing the detailed configuration of structure 800A. Fig. 69 is a front view showing the detailed configuration of structure 800A. Fig. 70 is a rear view showing the detailed configuration of structure 800A. Fig. 71 is a left side view showing the detailed configuration of structure 800A. Fig. 72 is a right side view showing the detailed configuration of structure 800A. Fig. 73 is a plan view showing the detailed configuration of structure 800A.

[0301] The structure 800A mainly has a front wall 110, a third guide rail 111, a fourth guide rail 112, a left side wall 820, a right side wall 830, and a ceiling 150. The structures and functions of the front wall 110, the third guide rail 111, the fourth guide rail 112, and the ceiling 150 are the same as those in the first embodiment, and therefore will not be described.

[0302] The left side wall 820 is in contact with the front wall 110, the ceiling 150, and the vertical wall V. The left side wall 820 is an example of a first component. The right side wall 830 is in contact with the front wall 110, the ceiling 150, and the vertical wall V. The right side wall 830 is an example of a first component.

[0303] The opening 151 may be provided in any one of the front wall 110, the left side wall 820, and the right side wall 830. The opening 152 may be provided in any one of the front wall 110, the left side wall 820, and the right side wall 830.

[0304] The interior 122 is formed by surrounding the area of ​​the floor F where the plant P is grown with the front wall 110, the left side wall 820, the right side wall 830, the ceiling 150, and the vertical wall V. Specifically, the left side wall 820 surrounds the left side of the area of ​​the floor F where the plant P is grown. Specifically, the right side wall 830 surrounds the left side of the area of ​​the floor F where the plant P is grown.

[0305] The inside I22 is isolated from the outside of the structure 800A and the passage 102 by the front wall 110, the left side wall 820, the right side wall 830, the ceiling 150, and the vertical wall V. The space between the inside I22, the outside of the structure 800A, and the passage 102 is covered by the front wall 110, the left side wall 820, the right side wall 830, the ceiling 150, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 800A and the passage 102 to the inside I22. Therefore, air supplied to the inside I22 through the opening 151 is unlikely to flow from the inside I22 to the outside of the structure 800A. Air in the space I24 is also unlikely to flow to the inside I22. It is difficult for people or equipment to approach the inside I22. People or equipment cannot secure a working space.

[0306] Plants P are grown in the inner side I22. A part of the bed F in the inner side I22 is filled with soil (not shown) in which the plants P can be planted or with a nutrient solution (not shown) in which the plants P can be immersed. In the inner side I22, the plants P are planted in soil or immersed in the nutrient solution.

[0307] Examples of the configuration of the left side wall 820 and the right side wall 830 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0308] The left wall 820 and the right wall 830 include a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I24 can be transmitted to the inside I22. Because the left wall 820 and the right wall 830 are transparent or semi-transparent, the plants P on the inside I22 can be seen through from the outside of the structure 800A.

[0309] The width of the structure 800A is a value that ensures D21 and D22. D21 is the shortest distance in the negative Z direction from the plant P to the left side wall 820 when the plant P has finished growing. D21 is preferably 1 to 10 centimeters, but is not limited to this. D22 is the shortest distance in the negative Z direction from the plant P to the right side wall 830 when the plant P has finished growing. D22 is preferably 1 to 10 centimeters, but is not limited to this.

[0310] The front wall 110 is a component that can change its shape. Therefore, the structure 800A is a variable structure. The structure 800A may further include a floor material (not shown). The floor material is in contact with the front wall 110, the vertical wall V, the left side wall 820, and the right side wall 830. The floor material is laid on the floor F of the inner side I22 (all or part of the floor F of the inner side I22). The opening 151 may be provided in the floor material. The opening 152 may be provided in the floor material. The inner side I22 is formed by being surrounded by the floor material in addition to the front wall 110, the vertical wall V, the left side wall 820, and the right side wall 830.

[0311] (3) Modifications A modification of the eighth embodiment will be described, focusing on the differences from the eighth embodiment, and omitting the description of the similarities to the eighth embodiment.

[0312] (3-1) Variation 8A The structure 800A and the structure 800B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0313] (3-2) Modification 8B The front wall 110 of the eighth embodiment and modification 8A may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by the control device.

[0314] <Ninth Embodiment> (1) Overall Configuration The overall configuration of the facility 9 according to the ninth embodiment will be described. Hereinafter, similarities between the first and ninth embodiments will be omitted, and the following description will focus on differences between the first and ninth embodiments. Figure 74 is a schematic diagram showing the overall configuration of the facility 9 according to the ninth embodiment. The facility 9 mainly includes a greenhouse 10 and an air conditioner 11.

[0315] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 900A and a structure 900B. The interior of the green house 10 is divided into an inside I25 of the structure 900A, an inside I26 of the structure 900B, and a space I27. The space I27 is outside the structures 900A and 900B and is inside the green house 10. Details of the structure 900A and the structure 900B will be described later.

[0316] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I25 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I26 via a hose (not shown) that is different from the hose that communicates with the inside I25. The hose that communicates with the air outlet of the air conditioner 11 and the inside I25 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I26 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I25 and the inside I26 via the hoses.

[0317] (2) Detailed Configuration The detailed configuration of the structure 900A and the structure 900B will be described. The structure 900A is a variable structure whose configuration can be changed by the operation of the structure 900A. The structure 900B is a variable structure whose configuration can be changed by the operation of the structure 900B. The structures of the structure 900A and the structure 900B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 900A and the structure 900B are similar. The structure and function of the structure 900A will be described below.

[0318] Fig. 75 is a perspective view showing the detailed configuration of the structure 900A. Fig. 76 is a front view showing the detailed configuration of the structure 900A. Fig. 77 is a rear view showing the detailed configuration of the structure 900A. Fig. 78 is a left side view showing the detailed configuration of the structure 900A. Fig. 79 is a right side view showing the detailed configuration of the structure 900A. Fig. 80 is a plan view showing the detailed configuration of the structure 900A.

[0319] The structure 900A mainly has a front wall 110, a third guide rail 111, a fourth guide rail 112, a left side wall 920, a ceiling 150, and a rear wall 940. The structures and functions of the front wall 110, the third guide rail 111, the fourth guide rail 112, and the ceiling 150 are the same as those in the first embodiment, and therefore will not be described.

[0320] The left side wall 920 is in contact with the front wall 110, the ceiling 150, and the rear wall 940. The left side wall 920 is an example of a first component. The rear wall 940 faces the front wall 110 and is in contact with the ceiling 150, the left side wall 920, and the vertical wall V.

[0321] The opening 151 may be provided in any one of the front wall 110, the left side wall 920, and the rear wall 940. The opening 152 may be provided in any one of the front wall 110, the left side wall 920, and the rear wall 940.

[0322] An interior I25 is formed by surrounding the area of ​​the floor F where the plant P is grown with the front wall 110, the left side wall 920, the rear wall 940, the ceiling 150, and the vertical wall V. Specifically, the left side wall 920 surrounds the left side of the area of ​​the floor F where the plant P is grown. The rear wall 940 surrounds the rear side of the area of ​​the floor F where the plant P is grown.

[0323] The inside I25 is isolated from the outside of the structure 900A and the passage 102 by the front wall 110, the left side wall 920, the rear wall 940, the ceiling 150, and the vertical wall V. The space between the inside I25, the outside of the structure 900A, and the passage 102 is covered by the front wall 110, the left side wall 920, the rear wall 940, the ceiling 150, and the vertical wall V. It is difficult for people, equipment, and air to pass from the outside of the structure 900A and the passage 102 to the inside I25. Therefore, air supplied to the inside I25 through the opening 151 is unlikely to flow from the inside I25 to the outside of the structure 900A. Air in the space I27 is also unlikely to flow to the inside I25. It is difficult for people or equipment to approach the inside I25. People or equipment cannot secure a working space.

[0324] Plants P are grown in the inner part I25. A part of the bed F in the inner part I25 stores soil (not shown) in which the plants P can be planted or a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I25, the plants P are planted in soil or immersed in the nutrient solution.

[0325] Examples of the configuration of the left side wall 920 and the rear wall 940 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0326] The left wall 920 and the rear wall 940 include a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I27 can be transmitted to the interior I25. Because the left wall 920 and the rear wall 940 are transparent or semi-transparent, the plants P on the interior I25 can be seen through from the outside of the structure 900A.

[0327] The front wall 110 is a component that can change its shape. Therefore, the structure 900A is a variable structure. The structure 900A may further include a floor material (not shown). The floor material is in contact with the front wall 110, the vertical wall V, the left side wall 920, and the rear wall 940. The floor material is laid on the floor F of the inner side I25 (all or part of the floor F of the inner side I25). The opening 151 may be provided in the floor material. The opening 152 may be provided in the floor material. The inner side I25 is formed by being surrounded by the floor material in addition to the front wall 110, the vertical wall V, the left side wall 920, and the rear wall 940.

[0328] (3) Modifications A modification of the ninth embodiment will be described, focusing on the differences from the ninth embodiment, and omitting the description of the similarities to the ninth embodiment.

[0329] (3-1) Modification 9A The facility 9 may include, instead of the structures 900A and 900B, a structure (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the structures 900A and 900B. The structure 900A has, instead of the left side wall 920, a right side wall (not shown) that is substantially symmetrical with respect to a plane extending in the X and Y directions to the left side wall 920.

[0330] (3-2) Variation 9B In the ninth embodiment or variation 9A, the structure 900A and the structure 900B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0331] (3-3) Modification 9C The front wall 110 of the ninth embodiment, Modification 9A, and Modification 9B may be modified by a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by the control device.

[0332] <Tenth Embodiment> (1) Overall Configuration The overall configuration of the facility 12 according to the tenth embodiment will be described. Hereinafter, similarities between the seventh embodiment and the tenth embodiment will be omitted, and the description will focus on differences between the seventh embodiment and the tenth embodiment. Figure 81 is a schematic diagram showing the overall configuration of the facility 12 according to the tenth embodiment. The facility 12 mainly includes a greenhouse 10 and an air conditioner 11.

[0333] (1-1) Greenhouse The interior of the green house 10 is mainly provided with a structure 1000A and a structure 1000B. The interior of the green house 10 is divided into an inside I28 of the structure 1000A, an inside I29 of the structure 1000B, and a space I30. The space I30 is outside the structures 1000A and 1000B and is inside the green house 10. Details of the structure 1000A and the structure 1000B will be described later.

[0334] (1-2) Air Conditioner The air outlet of the air conditioner 11 communicates with the inside I28 via a hose (not shown). The air outlet of the air conditioner 11 also communicates with the inside I29 via a hose (not shown) that is different from the hose that communicates with the inside I28. The hose that communicates with the air outlet of the air conditioner 11 and the inside I28 and the hose that communicates with the air outlet of the air conditioner 11 and the inside I29 are examples of first hoses. Air conditioned by the air conditioner 11 is supplied to the inside I28 and the inside I29 via the hoses.

[0335] (2) Detailed Configuration The detailed configuration of the structure 1000A and the structure 1000B will be described. The structure 1000A is a variable structure that can change the state of the structure 1000A by operating the structure 1000A. The structure 1000B is a variable structure that can change the state of the structure 1000B by operating the structure 1000B. The structures of the structure 1000A and the structure 1000B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the structure 1000A and the structure 1000B are similar. The structure and function of the structure 1000A will be described below.

[0336] Fig. 82 is a perspective view showing the detailed configuration of the structure 1000A. Fig. 83 is a front view showing the detailed configuration of the structure 1000A. Fig. 84 is a rear view showing the detailed configuration of the structure 1000A. Fig. 85 is a left side view showing the detailed configuration of the structure 1000A. Fig. 86 is a right side view showing the detailed configuration of the structure 1000A. Fig. 87 is a plan view showing the detailed configuration of the structure 1000A.

[0337] The structure 1000A mainly has a front wall 210, a third guide rail 111, a fourth guide rail 112, a rear wall 440, a left side wall 720, and a right side wall 1030. The structures and functions of the front wall 210, the third guide rail 111, the fourth guide rail 112, the rear wall 440, and the left side wall 720 are the same as those in the seventh embodiment, and therefore will not be described here.

[0338] The right side wall 1030 is in contact with the front wall 210, the ceiling C, and the rear wall 440. The right side wall 1030 is an example of a first component. The opening 451 may be provided in any of the front wall 210, the left side wall 720, or the right side wall 1030. The opening 452 may be provided in any of the front wall 210, the left side wall 720, or the right side wall 1030.

[0339] An interior I28 is formed by surrounding the area of ​​floor F where the plant P is grown with front wall 210, rear wall 440, ceiling C, left side wall 720, and right side wall 1030. Specifically, right side wall 1030 surrounds the right side of the area of ​​floor F where the plant P is grown.

[0340] The inside I28 is isolated from the outside of the structure 1000A and the passage 102 by the front wall 210, rear wall 440, ceiling C, right side wall 1030, and left side wall 720. The front wall 210, rear wall 440, ceiling C, right side wall 1030, and left side wall 720 provide a barrier between the inside I28 and the outside of the structure 1000A and the passage 102. It is difficult for people, equipment, and air to pass from the outside of the structure 1000A and the passage 102 to the inside I28. Therefore, air supplied to the inside I28 through the opening 451 is unlikely to flow from the inside I28 to the outside of the structure 1000A. Air in the space I30 is also unlikely to flow to the inside I28. It is difficult for people or equipment to approach the inside I28. People or equipment cannot secure a working space.

[0341] Plants P are grown in the inner part I28. A part of the floor F in the inner part I28 is filled with soil (not shown) in which the plants P can be planted or with a nutrient solution (not shown) in which the plants P can be immersed. In the inner part I28, the plants P are planted in soil or immersed in the nutrient solution.

[0342] Examples of the configuration of the right side wall 1030 include, but are not limited to, a configuration of a frame and vinyl covering the frame, a configuration of a frame and glass covering the frame, a configuration of a frame and a plastic film covering the frame, and a configuration in which the frame and a surface covering the frame are integrated.

[0343] The right side wall 1030 includes a transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I30 can be transmitted to the interior I28. Because the right side wall 1030 is transparent or semi-transparent, the plants P on the interior I28 can be seen through from the outside of the structure 1000A.

[0344] The width of the structure 1000A is a value that ensures D24, which is the shortest distance in the Z direction from the plant P to the right side wall 1030 when the plant P has finished growing. D24 is preferably, but not limited to, 1 to 10 centimeters.

[0345] The front wall 210 is a component that can be changed in shape. Therefore, the structure 1000A is a variable structure. The structure 1000A may further include a floor material (not shown). The floor material is in contact with the front wall 210, the rear wall 440, the right side wall 1030, and the left side wall 720. The floor material is laid on the floor F of the inner side I28 (all or part of the floor F of the inner side I28). The opening 451 may be provided in the floor material. The opening 452 may be provided in the floor material. The inner side I28 is formed by being surrounded by the floor material in addition to the front wall 210, the rear wall 440, the ceiling C, the right side wall 1030, and the left side wall 720.

[0346] (3) Modifications A modification of the tenth embodiment will be described, focusing on the differences from the tenth embodiment, and omitting the description of the similarities to the tenth embodiment.

[0347] (3-1) Variant 10A The structure 1000A and the structure 1000B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0348] (3-2) Modification 10B The front wall 210 of the tenth embodiment and modification 10A may be changed in shape by control of a control device (not shown). In other words, the slat SL may slide on the third guide rail 111 and the fourth guide rail 112 by control of the control device.

[0349] <Eleventh Embodiment> (1) Overall Configuration The overall configuration of the facility 13 according to the eleventh embodiment will be described. Hereinafter, similarities between the eleventh embodiment and the first embodiment will be omitted, and differences between the eleventh embodiment and the first embodiment will be mainly described. Figure 88 is a schematic diagram showing the overall configuration of the facility 13 according to the eleventh embodiment. The facility 13 mainly includes a greenhouse 10 and an air conditioner 11.

[0350] The interior of the greenhouse 10 is mainly provided with a structure 1300A and a structure 1300B. The interior of the greenhouse 10 is divided into an inside I31 of the structure 1300A, an inside I32 of the structure 1300B, and a space I33. The space I33 is outside the structures 1300A and 1300B and is inside the greenhouse 10. Details of the structure 1300A and the structure 1300B will be described later.

[0351] The air conditioner 11 conditions the air in the inside 131 and the inside 132. The air outlet of the air conditioner 11 is connected to the inside 131 and the inside 132 by a hose (an example of a first hose, not shown). The air conditioned by the air conditioner 11 is supplied to the inside 131 and the inside 132 via the hose.

[0352] (2) Detailed Configuration The detailed configuration of the structure 1300A and the structure 1300B will be described. The structure 1300A is a variable structure whose configuration can be changed by the operation of the structure 1300A. The structure 1300B is a variable structure whose configuration can be changed by the operation of the structure 1300B. A variable structure is a structure whose configuration can be changed. The structures of the structure 1300A and the structure 1300B are approximately symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 1300A and the function of the structure 1300B are similar. The structure and function of the structure 1300A will be described below.

[0353] 89 is a perspective view showing the detailed configuration of the structure 1300A. The structure 1300A mainly has a front wall 1310, a first guide rail 612, a second guide rail 613, a case 614, a left side wall 1320, a right side wall 1330, a rear wall 1340, and a ceiling 1350. The first guide rail 612, the second guide rail 613, and the case 614 are the same as those in the sixth embodiment, and therefore description thereof will be omitted.

[0354] The front wall 1310 is mainly composed of a plurality of slats SL. The slats SL are the same as those in the sixth embodiment, and therefore a description thereof will be omitted. The front wall 1310 faces the passage 102.

[0355] The left side wall 1320 faces the right side wall 1330 and is in contact with the front wall 1310, the rear wall 1340, and the ceiling 1350. The right side wall 1330 faces the left side wall 120 and is in contact with the front wall 1310, the rear wall 1340, and the ceiling 1350. An opening 1331 that communicates with the outside of the structure 1300A is provided in the right side wall 1330.

[0356] The opening 1331 is an example of an exhaust port. Air from the inside I31 is exhausted from the inside I31 to the outside of the structure 1300A through the opening 1331. For example, the opening 1331 is connected to a hose (an example of a second hose, not shown) that is connected to the air intake of the air conditioner 11. The air from the inside I31 flows into the air intake of the air conditioner 11 via the opening 1331 and the hose. The opening 1331 may be provided in any of the front wall 1310, the left side wall 1320, the rear wall 1340, or the ceiling 1350.

[0357] The rear wall 1340 faces the front wall 1310 and is in contact with the left side wall 1320, the right side wall 1330, and the ceiling 1350. The ceiling 1350 faces the ground T and is in contact with the front wall 1310, the left side wall 1320, the right side wall 1330, and the rear wall 1340.

[0358] An opening O is provided in the ground T on the inside I31. The opening O is an example of a supply port. The opening O is a hose (an example of a first hose, not shown) buried in the ground T, and is connected to a hose that is connected to an air outlet of the air conditioner 11. Air conditioned by the air conditioner 11 is supplied to the inside I31 through the opening O.

[0359] An interior I31 is formed by surrounding the area where the plant P is grown with a front wall 1310, a left wall 1320, a right wall 1330, a rear wall 1340, and a ceiling 1350. Specifically, the front side of the area where the plant P is grown is surrounded by the front wall 1310. The left side of the area where the plant P is grown is surrounded by the left wall 1320. The right side of the area where the plant P is grown is surrounded by the right wall 1330. The rear side of the area where the plant P is grown is surrounded by the rear wall 1340. The upper side of the area where the plant P is grown is surrounded by the ceiling 1350.

[0360] The inside I31 is isolated from the outside of the structure 1300A and the passage 102 by the front wall 1310, left side wall 1320, right side wall 1330, rear wall 1340, and ceiling 1350. The inside I31 is isolated by the structure 1300A from the flow of air, access by people, and access by equipment from the outside of the structure 1300A and the passage 102. People, equipment, and air are less likely to pass from the outside of the structure 1300A and the passage 102 to the inside I31. Therefore, air supplied to the inside I31 through the opening O is less likely to flow from the inside I31 to the outside of the structure 1300A. Air in the space I33 is also less likely to flow to the inside I31. People or equipment are less likely to approach the inside I31. People or equipment cannot secure work space. Work space is the space necessary for agricultural work.

[0361] Plants P are grown in the inner part I31. Soil (not shown) in which the plants P can be planted or nutrient solution (not shown) in which the plants P can be immersed is stored in a part or all of the ground T in the inner part I31. In the inner part I31, the plants P are planted in soil or immersed in nutrient solution.

[0362] Examples of the configurations of the left side wall 1320, the right side wall 1330, the rear wall 1340, the ceiling 1350, and the slats SL include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0363] The front wall 1310 (nine slats SL), the left wall 1320, the right wall 1330, the rear wall 1340, and the ceiling 1350 include transparent or semi-transparent vinyl, glass, or plastic film so that light from the lighting in the space I33 is transmitted to the interior I31. Because the front wall 1310 (nine slats SL), the left wall 1320, the right wall 1330, the rear wall 1340, and the ceiling 1350 are transparent or semi-transparent, the plants P on the interior I31 can be seen through from the outside of the structure 1300A.

[0364] The depth of the structure 1300A is a value that ensures D25 and D26. D25 is the shortest distance in the X direction from the plant P to the front wall 1310 when the plant P has finished growing. D25 is preferably 1 to 10 centimeters, but is not limited to this. D26 is the shortest distance in the negative X direction from the plant P to the rear wall 1340 when the plant P has finished growing. D26 is preferably 1 to 10 centimeters, but is not limited to this.

[0365] The height of the structure 1300A is a value that ensures D27, which is the shortest distance in the Y direction from the plant P to the ceiling 1350 when the plant P has finished growing. D27 is preferably, but not limited to, 1 to 10 centimeters.

[0366] The width of the structure 1300A is a value that ensures D28 and D29. D28 is the shortest distance in the negative Z direction from the plant P to the left side wall 1320 when the plant P has finished growing. D28 is preferably, but not limited to, 1 to 10 centimeters. D29 is the shortest distance in the Z direction from the plant P to the right side wall 1330 when the plant P has finished growing. D29 is preferably, but not limited to, 1 to 10 centimeters.

[0367] The left side wall 1320, the right side wall 1330, the rear wall 1340, and the ceiling 1350 are components that cannot be changed in shape. The front wall 1310 is a component that can be changed in shape. Therefore, the structure 1300A is a variable structure. Note that at least one of the left side wall 1320, the right side wall 1330, the rear wall 1340, and the ceiling 1350 may be a component that can be changed in shape.

[0368] The structure 1300A may further include a flooring material (not shown). The flooring material faces the ceiling 1350 and is in contact with the front wall 1310, the left side wall 1320, the right side wall 1330, and the rear wall 1340. The opening 1331 may be provided in the flooring material.

[0369] Below, we will explain an embodiment of the structure 1300A that is different from the embodiment in Figure 89. Figure 90 is a perspective view showing the detailed configuration of the structure 1300A. The embodiment in Figure 90 is an embodiment in which the slats SL have been slid in the Y direction from the embodiment in Figure 89. Nine slats SL are housed in a case 614. The outside and passage 102 of the structure 1300A are connected to the inside I31 via the front side of the structure 1300A. Because a work space is secured, a person or device performing agricultural work can perform agricultural work on plants P via the front side of the structure 1300A.

[0370] 89 is also an embodiment in which the slat SL is slid in the minus Y direction from the embodiment in Fig. 90. By changing the embodiment of the front wall 1310, the state in which the outside of the structure 1300A and the passage 102 are connected to the inside I31 is changed to a state in which the outside of the structure 1300A and the passage 102 are blocked from the inside I31.

[0371] (3) Modifications A modification of the eleventh embodiment will be described below, focusing on the differences from the eleventh embodiment, and omitting the description of the similarities to the eleventh embodiment.

[0372] (3-1) Modification 11A An opening X may be provided in the ground T on the inside I31. FIG. 91 is a perspective view showing a structure 1300A according to modification 11A. The opening X is an example of an exhaust port. Air on the inside I31 is exhausted from the inside I31 to the outside of the structure 1300A through the opening X. For example, the opening X is connected to a hose (an example of a second hose, not shown) that is connected to the air intake of the air conditioner 11. The air on the inside I31 flows into the air intake of the air conditioner 11 via the opening X and the hose.

[0373] (3-2) Variation 11B The structure 1300A and the structure 1300B may be provided inside any of the mushroom cultivation facility 20, the plant factory 30, the server room 40, the warehouse 50, the livestock barn 60, and the land-based farm 70.

[0374] For example, Figure 92 is a plan view showing the detailed configuration of a structure 1300A. An opening O is provided in the floor of the server room 40 on the inside I31. The opening O is an example of a supply port. The opening O is an underfloor air passage (not shown) of the server room 40, and is connected to an air passage that is connected to the air outlet of the air conditioner 11. Air conditioned by the air conditioner 11 is supplied to the inside I1 via the underfloor air passage and the opening O. On the inside I31, so-called "floor-outlet air conditioning" is performed by the underfloor air passage and the opening O.

[0375] (3-3) Modification 11C The shape of the front wall 1310 may be changed by the control of a control device (not shown). In other words, the slat SL may be slid along the first guide rail 612 and the second guide rail 613 by the control of the control device.

[0376] (4) Features (4-1) A variable structure is installed inside another structure. In the inside I31 and inside I32 of the variable structure, plants P or mushrooms M are cultivated, livestock L are raised, aquatic organisms Q are farmed, merchandise G is stored, or a server SV is installed. The variable structure has a front wall 1310, a ceiling 1350, a rear wall 1340, a left side wall 1320, and a right side wall 1330. The front wall 1310 can be changed and erected inside. The ceiling 1350 is in contact with the front wall 1310. The rear wall 1340 is erected inside, faces the front wall 1310, and is in contact with the ceiling 1350. The left side wall 1320 is erected inside and is in contact with the front wall 1310, the ceiling 1350, and the rear wall 1340. The right side wall 1330 is erected inside, faces the left side wall 1320, and is in contact with the front wall 1310, the ceiling 1350, and the rear wall 1340. The insides I31 and I32 are formed by the front wall 1310, the ceiling 1350, the rear wall 1340, the left side wall 1320, and the right side wall 1330. Supply ports for supplying conditioned air from the air conditioner 11 to the insides I31 and I32 are provided on the ground T on the insides I31 and I32 or on the floor of another structure on the insides I31 and I32. By changing the shape of the front wall 1310, a state in which the outside of the variable structure is isolated from the insides I31 and I32 can be changed to a state in which the outside is connected to the insides I31 and I32.

[0377] Therefore, the variable structure can achieve energy savings in the cultivation of plants P and reduce costs associated with the cultivation of plants P.
