[0010] (Example 1) The following embodiments all show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components shown in the following embodiments, as well as the steps (processes) and the order of the steps, etc. are only examples and not intended to limit the present disclosure. Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the most basic concept of the present disclosure are described as arbitrary components. Also, in each figure, the same reference numerals are given to substantially the same configurations, and duplicate descriptions are omitted or simplified.

[0011] Figs. 1(a)-(b) are perspective views of an air-conditioned space generation system 1000. Fig. 1(a) is a perspective view showing the appearance of a building 10 in which the air-conditioned space generation system 1000 is installed. The air-conditioned space generation system 1000 may be installed in an indoor open space. The building 10 is, for example, a single-story store. The building 10 is not limited thereto, but an air-conditioned space by the air-conditioned space generation system 1000 is generated in the first-floor part. An eaves 20 is provided on one side surface of the box-shaped building 10, and the lower part under the eaves 20 is the under-eaves 22. The wall of the building 10 at the under-eaves 22 is the outer wall 24. A door 26 is provided on the outer wall 24. Also, a front wall 30, a left wall 32, and a right wall 34 are provided on a part of the outer wall 24, and a space 60 is formed by being surrounded by the front wall 30, the left wall 32, and the right wall 34. The front wall 30 is a wall provided along the outer wall 24 and on the front side of the outer wall 24 in the upper part of the outer wall 24. The left wall 32 and the right wall 34 are walls extending forward from the outer wall 24 and are provided side by side while being spaced apart.

[0012] FIG. 1(b) is a partial perspective view of the building 10 in FIG. 1(a) as seen from below, showing the portions of the front wall 30, the left wall 32, and the right wall 34. The outer wall 24 of the portion surrounded by the front wall 30, the left wall 32, and the right wall 34 is shown as the rear surface 40. The surface of the left wall 32 on the side of the right wall 34 is the left surface 42, and the surface of the right wall 34 on the side of the left wall 32 is the right surface 44. Therefore, the left surface 42 and the right surface 44 face each other. The lower surface of the front wall 30 is the upper surface 46. Also, the floor surface or the ground surface facing the upper surface 46 is the lower surface 48. By being surrounded by such a rear surface 40, left surface 42, right surface 44, upper surface 46, and lower surface 48, the aforementioned space 60 is formed. The front side of the space 60 is an opening 50. That is, the space 60 has a box-shaped configuration with an open front side.

[0013] On the front side portion of the upper surface 46, the first air outlet 110a, the first air inlet 112a, the second air inlet 112b, and the second air outlet 110b are arranged in order from the left surface 42 to the right surface 44. The first air outlet 110a and the second air outlet 110b are collectively referred to as the air outlet 110, and the first air inlet 112a and the second air inlet 112b are collectively referred to as the air inlet 112. The number of the air inlets 112 is not limited to "2". That is, one or more air inlets 112 may be arranged between the first air outlet 110a and the second air outlet 110b.

[0014] The first air outlet 110a and the second air outlet 110b blow out the air conditioned in an air conditioner 100 (not shown) described later into the space 60. The first air inlet 112a and the second air inlet 112b suck the air in the space 60 toward the air conditioner 100. In this embodiment, it is assumed that the air conditioning by the air conditioner 100 is a cooling operation. Also, although the air flow in the space 60 will be described later, the air conditioning space generation system 1000 generates an air conditioning space in the space 60.

[0015] An outside air temperature sensor 102 is installed on the right wall 34, on the side opposite to the right side 44. The installation location of the outside air temperature sensor 102 is not limited to this location; it can be installed outside the space 60. It is desirable that the outside air temperature sensor 102 be installed at a position higher than the air outlet 110. The outside air temperature sensor 102 measures the temperature outside the space 60 (hereinafter referred to as "outside air temperature"). Since known techniques can be used for temperature measurement by the outside air temperature sensor 102, a detailed explanation is omitted here. The uses of the outside air temperature measured by the outside air temperature sensor 102 will be described later.

[0016] Figures 2(a) and 2(b) are cross-sectional views of the air-conditioned space generation system 1000. Figure 2(a) is a front-to-back cross-sectional view of the building 10 in Figure 1(a), and Figure 2(b) is a perspective view of the building 10 in Figure 1(a) as seen from above. Figures 3(a) and 3(b) are cross-sectional perspective views of the air-conditioned space generation system 1000. Figure 3(a) is a cross-sectional view of section AA of Figure 2(a), and Figure 3(b) is a cross-sectional view of section BB of Figure 2(a). An upper space 62 is provided above the top surface 46 and between the front wall 30 and the rear surface 40. In addition, a rear space 64 is provided behind the rear surface 40, that is, inside the building 10. The rear space 64 is, for example, a living room or shop in the building 10. The first air conditioner 100a and the second air conditioner 100b are installed in the rear space 64. The first air conditioner 100a and the second air conditioner 100b are collectively referred to as air conditioner 100. As described above, in this embodiment, air conditioner 100 performs cooling operation. The boundary between the upper space 62 and the rear space 64 is indicated as the boundary surface 70.

[0017] On the interface 70, the first exhaust port 120a, the first air intake port 122a, the second air intake port 122b, and the second exhaust port 120b are arranged in order from the left side 42 to the right side 44. The first exhaust port 120a and the second exhaust port 120b are collectively referred to as exhaust port 120, and the first air intake port 122a and the second air intake port 122b are collectively referred to as air intake port 122. The air conditioner 100 draws in air from the rear space 64, cools the drawn-in air, and then blows out the cooled air. For example, the air conditioner 100 draws in some air from the air intake port 122, cools the drawn-in air, and then blows out some of the cooled air to the exhaust port 120.

[0018] The upper space 62 is equipped with the first exhaust duct 130a and the second exhaust duct 130b, collectively referred to as the exhaust duct 130; the first supply air duct 132a and the second supply air duct 132b, collectively referred to as the supply air duct 132; the first line grille 134a to the fourth line grille 134d, collectively referred to as the line grille 134; and the control device 140.

[0019] The first exhaust port 120a is connected to the first air outlet 110a via the first exhaust duct 130a and the first line grille 134a. The first exhaust duct 130a is a hollow tube, and the first line grille 134a has a hollow structure. Therefore, an air passage is formed at the first exhaust port 120a, the first exhaust duct 130a, the first line grille 134a, and the first air outlet 110a.

[0020] The first air intake port 122a is connected to the first suction port 112a via the first air intake duct 132a and the second line grille 134b. The first air intake duct 132a is a hollow tube, and the second line grille 134b has a hollow structure. Therefore, an air passage is formed at the first air intake port 122a, the first air intake duct 132a, the second line grille 134b, and the first suction port 112a.

[0021] The second air intake port 122b is connected to the second suction port 112b via the second air intake duct 132b and the third line grille 134c. The second air intake duct 132b is a hollow tube, and the third line grille 134c has a hollow structure. Therefore, an air passage is formed at the second air intake port 122b, the second air intake duct 132b, the third line grille 134c, and the second suction port 112b.

[0022] The second exhaust port 120b is connected to the second air outlet 110b via the second exhaust duct 130b and the fourth line grille 134d. The second exhaust duct 130b is a hollow tube, and the fourth line grille 134d has a hollow structure. Therefore, an air passage is formed at the second exhaust port 120b, the second exhaust duct 130b, the fourth line grille 134d, and the second air outlet 110b.

[0023] Figure 4 is a front view of the air conditioning space generation system 1000. Figures 5(a)-(b) are cross-sectional perspective views of the air conditioning space generation system 1000. These are cross-sectional views of the CC of Figure 4. A first exhaust fan 150a is installed inside the first exhaust duct 130a. The first exhaust fan 150a blows air from the first exhaust port 120a to the first outlet 110a. This airflow is shown as the discharge flow 400. In addition, a discharge temperature sensor 104 is placed inside the first exhaust duct 130a, particularly between the first exhaust fan 150a and the first line grill 134a. The discharge temperature sensor 104 measures the temperature of the air sent to the first outlet 110a by the first exhaust fan 150a (hereinafter referred to as "discharge temperature"). Since known techniques can be used for measuring the temperature in the discharge temperature sensor 104, a detailed explanation is omitted here. Furthermore, the uses of the discharge temperature measured by the discharge temperature sensor 104 will be described later.

[0024] Here, the discharge direction 80 of the first air outlet 110a is inclined 0 to 10° toward the rear surface 40 from the straight line extending from the top surface 46 to the bottom surface 48. This is to suppress the leakage of air blown out from the first air outlet 110a to the space 60. If the discharge direction 80 is directed away from the space 60, the amount of air blown out from the first air outlet 110a that leaks out of the space 60 increases, so the temperature of the air drawn into the air outlet 110 (described later) becomes higher, and the energy efficiency decreases. On the other hand, if the discharge direction 80 is directed more than 0 to 10° toward the rear surface 40, the air blown out from the first air outlet 110a has difficulty reaching the front and bottom of the space 60, and the uniformity of the air conditioning decreases.

[0025] A second exhaust fan 150b (not shown) is placed inside the second exhaust duct 130b. The second exhaust fan 150b blows air from the second exhaust port 120b to the second outlet 110b. The second exhaust fan 150b is configured in the same way as the first exhaust fan 150a, and the first exhaust fan 150a and the second exhaust fan 150b are collectively referred to as exhaust fan 150. On the other hand, an outlet temperature sensor 104 may or may not be placed inside the second exhaust duct 130b.

[0026] Figure 6 is a cross-sectional perspective view of the air conditioning space generation system 1000. This is a cross-sectional view DD of Figure 4. A first supply air blower 152a is installed in the first supply air duct 132a. The first supply air blower 152a blows air from the first intake port 112a to the first supply air port 122a. This airflow is shown as the intake flow 402. A second supply air blower 152b (not shown) is installed in the second supply air duct 132b. The second supply air blower 152b blows air from the second intake port 112b to the second supply air port 122b.

[0027] In the above configuration, the air-conditioned space generation system 1000 includes an air conditioner 100, an outside air temperature sensor 102, an outlet temperature sensor 104, an outlet 110, an intake port 112, an exhaust port 120, an intake port 122, an exhaust duct 130, an intake duct 132, a line grille 134, a control device 140, an exhaust fan 150, and an intake fan 152.

[0028] Figure 7 shows the airflow in the air conditioning space generation system 1000 shown in Figures 1(a)-(b). Air blown out from the air conditioner 100 is blown out downwards as an outflow 400 from the outlet 110 via the exhaust port 120 and exhaust duct 130. The outflow 400 diffuses when it collides with the bottom surface 48. Since the space 60 is surrounded by the left surface 42 and the right surface 44, the outflow 400 that collides with the bottom surface 48 moves towards the center of the space 60. Near the center of the space 60, the outflow 400 blown out from the first outlet 110a and the outflow 400 blown out from the second outlet 110b collide and rise as an intake flow 402. The intake flow 402 is drawn into the first intake port 112a and the second intake port 112b. As a result, an air-conditioned space is formed by the flow of the discharge flow 400 and the intake flow 402 within the space 60.

[0029] Next, control by the control device 140 will be described. The outside air temperature sensor 102, the outlet temperature sensor 104, the control device 140, the exhaust fan 150, and the supply fan 152 are capable of wireless or wired communication. The control device 140 receives the outside air temperature from the outside air temperature sensor 102 and the outlet temperature from the outlet temperature sensor 104. The outlet temperature sensor 104 may average the outside air temperature and the outlet temperature over a certain period of time. The control device 140 calculates the differential temperature from the difference between the outside air temperature and the outlet temperature as follows. Temperature difference = outside air temperature - outlet temperature

[0030] The control device 140 stores a first threshold and a second threshold in advance. For example, the first threshold is set to be greater than the second threshold. Alternatively, the first threshold and the second threshold may be equal. The control device 140 decides to increase the airflow rate of the exhaust fan 150 when the differential temperature is greater than the first threshold. The control device 140 sends an instruction to increase the airflow rate to the exhaust fan 150, and the exhaust fan 150 increases its airflow rate upon receiving the instruction to increase the airflow rate.

[0031] When the temperature difference is greater than the first threshold, it occurs when the outside air temperature rises above the standard condition. The standard condition is the average outside air temperature when the cooling operation is performed. In such a situation, the discharge flow 400 near the bottom surface 48 is less likely to rise as an intake flow 402 due to collision. As a result, the discharge flow 400 that descends to the bottom surface 48 leaks out of the space 60, reducing the amount of intake flow 402 and lowering energy efficiency. In this embodiment, the airflow rate of the exhaust fan 150 is increased in order to increase the amount of intake flow 402.

[0032] Furthermore, if the temperature difference is greater than the first threshold, this also occurs when the discharge temperature drops below the standard state. In such situations, the discharge flow 400 near the lower surface 48 is less likely to rise as an intake flow 402 due to collision. As a result, the discharge flow 400 that descends to the lower surface 48 leaks out of the space 60, reducing the amount of intake flow 402 and lowering energy efficiency. In this embodiment, the airflow of the exhaust fan 150 is increased in order to increase the amount of intake flow 402.

[0033] The control device 140 may decide to increase the airflow rate of the supply air blower 152 if the differential temperature is greater than a first threshold. The control device 140 sends an instruction to increase the airflow rate to the supply air blower 152, and the supply air blower 152 increases its airflow rate upon receiving the instruction to increase the airflow rate.

[0034] On the other hand, the control device 140 decides to reduce the airflow of the exhaust fan 150 when the differential temperature is less than the second threshold. The control device 140 sends an instruction to reduce the airflow to the exhaust fan 150, and the exhaust fan 150 reduces the airflow when it receives an instruction to increase the airflow.

[0035] When the temperature difference is less than the second threshold, it occurs when the ambient temperature drops below standard conditions. In such situations, the discharge flow 400 is more likely to rise as the intake flow 402 due to collisions. As a result, the discharge flow 400 collides and leaks out of the space 60 before reaching the bottom surface 48, reducing energy efficiency. To reduce the amount of discharge flow 400, in this embodiment, the airflow rate of the exhaust fan 150 is reduced.

[0036] Furthermore, if the temperature difference is less than the second threshold, this also occurs when the outlet temperature rises above the standard state. The outlet flow 400 is more likely to rise as an intake flow 402 due to collisions. As a result, the outlet flow 400 collides and leaks out of the space 60 before reaching the bottom surface 48, thus reducing energy efficiency. In this embodiment, to reduce the amount of outlet flow 400, the airflow rate of the exhaust fan 150 is reduced.

[0037] The control device 140 may decide to reduce the airflow rate of the supply air blower 152 if the differential temperature is less than the second threshold. The control device 140 sends an instruction to reduce the airflow rate to the supply air blower 152, and the supply air blower 152 reduces its airflow rate upon receiving the instruction to reduce the airflow rate. In the above process, if the airflow rate of the exhaust air blower 150 is made greater than that of the supply air blower 152, ventilation of the rear space 64 is also performed. In addition, the thermal transmittance of the exterior wall 24 is 6 W / m 2 • It will be set to K or higher.

[0038] The subject of the apparatus, system, or method in this disclosure comprises a computer. The functions of the subject of the apparatus, system, or method in this disclosure are realized by the computer executing a program. The computer comprises a processor as its main hardware component, which operates according to the program. The processor is of any type as long as it can realize its functions by executing the program. The processor consists of one or more electronic circuits, including semiconductor integrated circuits (ICs) or LSIs (Large Scale Integrations). Multiple electronic circuits may be integrated on one chip or provided on multiple chips. Multiple chips may be aggregated in one device or provided on multiple devices. The program is recorded on a non-temporary recording medium such as a ROM, optical disc, or hard disk drive that is readable by the computer. The program may be pre-stored on the recording medium or supplied to the recording medium via a wide-area communication network, including the Internet.

[0039] The operation of the air-conditioned space generation system 1000 with the above configuration will now be explained. Figure 8 is a flowchart showing the airflow control procedure in the air-conditioned space generation system 1000. The control device 140 calculates the differential temperature by subtracting the discharge temperature from the outside air temperature (S10). If the differential temperature is greater than the first threshold (Y in S12), the control device 140 increases the airflow of the exhaust fan 150 (S14). On the other hand, if the differential temperature is not greater than the first threshold (N in S12), and if the differential temperature is less than the second threshold (Y in S16), the control device 140 decreases the airflow of the exhaust fan 150 (S18). If the differential temperature is not less than the second threshold (N in S16), the process is terminated.

[0040] In this embodiment, the first air outlet 110a, the intake port 112, and the second air outlet 110b are arranged in order from the left side 42 to the right side 44 on the upper surface 46, so that an intake flow 402 can be generated based on the difference between the discharge temperature and the outside air temperature. Furthermore, since the intake flow 402 is generated based on the difference between the discharge temperature and the outside air temperature, an air-conditioned space can be created in outdoor environments or indoor open spaces. Furthermore, since the intake flow 402 is generated based on the difference between the discharge temperature and the outside air temperature, the intake port 112 can draw in the intake flow 402. Furthermore, since the intake flow 402 is drawn in at the intake port 112, energy efficiency can be improved. In addition, since the first air outlet 110a, the intake port 112, and the second air outlet 110b are arranged on the front part of the upper surface 46, a uniform air-conditioned space can be created in the space 60. Furthermore, since the air outlet 110 is oriented at an angle of 0 to 10° towards the rear surface 40, a uniform air-conditioned space can be created in the space 60.

[0041] Furthermore, since the airflow rate of the exhaust fan 150 is adjusted based on the ambient temperature and the outlet temperature, the amount of suction flow 402 can be increased. Also, since the amount of suction flow 402 is increased, energy efficiency can be improved. In addition, the differential temperature is calculated from the difference between the ambient temperature and the outlet temperature, and if the differential temperature is greater than the first threshold, the airflow rate of the exhaust fan 150 is increased, and if the differential temperature is less than the second threshold, the airflow rate of the exhaust fan 150 is decreased, thus increasing the amount of suction flow 402. Also, since the first threshold and the second threshold are equal, the amount of suction flow 402 can be increased. Furthermore, the air outlet 110 and the exhaust port 120 are connected by an exhaust duct 130, the air intake port 112 and the air supply port 122 are connected by an air supply duct 132, an exhaust fan 150 is placed inside the exhaust duct 130, and an air supply fan 152 is placed inside the air supply duct 132, thus simplifying the configuration.

[0042] (Example 2) Next, Example 2 will be described. Example 2 relates to an air-conditioned space generation system 1000 that generates an air-conditioned space in space 60, similar to Example 1. In Example 1, an air conditioner 100 installed in the rear space 64 is used to generate the air-conditioned space. On the other hand, the air-conditioned space generation system 1000 according to Example 2 is equipped with an air conditioner 100 in the upper space 62. Here, the differences from Example 1 will be explained in detail.

[0043] Figures 9(a) and 9(b) are perspective views of the air conditioning space generation system 1000. Figure 9(a) is a partial perspective view from above of the front wall 30, left wall 32, and right wall 34 of the building 10 in Figure 1(a), and Figure 9(b) is a partial perspective view from below of the front wall 30, left wall 32, and right wall 34 of the building 10 in Figure 1(a). As before, the front wall 30, left wall 32, right wall 34, and outside air temperature sensor 102 are installed, and the rear surface 40, left surface 42, right surface 44, top surface 46, bottom surface 48, and opening 50 are arranged, forming a space 60. Also as before, on the front part of the top surface 46, the first air outlet 110a, first air inlet 112a, second air inlet 112b, and second air outlet 110b are arranged in order from the left surface 42 to the right surface 44.

[0044] On the other hand, in the opening 50, the first front vertical plate 36a is connected to the left side 42, and the second front vertical plate 36b is connected to the right side 44. The first front vertical plate 36a and the second front vertical plate 36b are collectively referred to as the front vertical plate 36. Such front vertical plates 36 reduce the area of ​​the opening 50. The front vertical plates 36 may also be provided in Embodiment 1. In addition, the upper side of the front wall 30 is covered with a removable top cover 200.

[0045] Figure 10 is a perspective view of the air conditioning space generation system 1000 with the top cover 200 removed. An upper space 62 is provided above the top surface 46. The upper space 62 is divided into a first upper space 62a, a second upper space 62b, and a third upper space 62c. Of these, the first upper space 62a is located in the center, the second upper space 62b is located on the left wall 32 side, and the third upper space 62c is located on the right wall 34 side.

[0046] The first upper space 62a is arranged with an air conditioner 100, a first blower 240a and a second blower 240b, collectively referred to as the blower 240. The second upper space 62b is arranged with a control device 140, a first duct 242a and a first line grille 244a, and the third upper space 62c is arranged with a second duct 242b and a second line grille 244b. The first blower 240a and the second blower 240b are collectively referred to as the blower 240, the first duct 242a and the second duct 242b are collectively referred to as the duct 242, and the first line grille 244a and the second line grille 244b are collectively referred to as the line grille 244.

[0047] The configuration of the first upper space 62a to the third upper space 62c will be described in detail below, using Figures 11 to 13(a)-(b). Figure 11 is a front view of the air conditioning space generation system 1000. Figures 12(a)-(c) are cross-sectional perspective views of the air conditioning space generation system 1000. These are cross-sectional views of the FF in Figure 11. The support plate 230 provided in the first upper space 62a is a rectangular plate, and the support plate 230 divides the upper part of the first upper space 62a into front and rear sections. The lower part of the support plate 230 penetrates from front to back. An air conditioner 100 is installed on the front side of the support plate 230. An air conditioning intake port 106 is located above the air conditioner 100, and an air conditioning outlet port 108 is located below the air conditioner 100.

[0048] A boundary plate 210 having an L-shaped cross-section is positioned in front of the air conditioner 100. The boundary plate 210 forms the boundary between an intake space 220, which connects the first intake port 112a, the second intake port 112b, and the air conditioning intake port 106 of the air conditioner 100, and an outlet space 222, which includes the air conditioning outlet 108 of the air conditioner 100, in the first upper space 62a. As shown in Figure 12(a), in the intake space 220, the airflow drawn in from the first intake port 112a and the second intake port 112b (hereinafter referred to as "intake flow 402") is guided along the boundary plate 210 to the air conditioning intake port 106.

[0049] As shown in Figure 12(b), the airflow (hereinafter referred to as "outlet flow 400") blown out from the air conditioning outlet 108 travels through the outlet space 222, passing under the support plate 230 to the first blower 240a and the second blower 240b. The first blower 240a and the second blower 240b correspond to the exhaust blower 150. Here, openings (hereinafter referred to as "bypass openings 212") are provided on both sides of the air conditioner 100. The bypass openings 212 connect the intake space 220 and the outlet space 222 in the upper space 62. As shown in Figure 12(c), a portion of the intake flow 402 in the intake space 220 passes through the bypass openings 212 and enters the outlet space 222, traveling through the outlet space 222 to the first blower 240a and the second blower 240b. Here, the suction flow 402 that enters the discharge space 222 is mixed with the discharge flow 400. Therefore, this suction flow 402 is considered to be included in the discharge flow 400.

[0050] Figures 13(a) and 13(b) are cross-sectional perspective views of the air conditioning space generation system 1000. Figure 13(a) is a cross-sectional view of GG in Figure 11. This is shown similarly to Figure 12(c), where the suction flow 402 drawn in from the first intake port 112a passes through the intake space 220, the bypass opening 212, and the discharge space 222 to the first blower 240a and the second blower 240b.

[0051] Figure 13(b) is a cross-sectional view of HH in Figure 11. Within the second upper space 62b, the first duct 242a is a hollow tube connecting the first blower 240a (not shown) and the first line grille 244a. The first line grille 244a has a hollow structure and is connected to the first outlet 110a. Therefore, an airflow path is formed from the first blower 240a through the first duct 242a, the first line grille 244a, and the first outlet 110a. The discharge flow 400 from the first blower 240a passes through the first duct 242a and the first line grille 244a and is blown out from the first outlet 110a. An outlet temperature sensor 104 is located in the first duct 242a.

[0052] The interior of the third upper space 62c is configured similarly to the interior of the second upper space 62b. In the third upper space 62c, the second duct 242b is installed in place of the first duct 242a, the second line grille 244b is installed in place of the first line grille 244a, and the second outlet 110b is installed in place of the first outlet 110a.

[0053] In the above configuration, the air conditioning space generation system 1000 also includes a top cover 200, a boundary plate 210, a bypass opening 212, a blower 240, a duct 242, and a line grille 244.

[0054] Figure 14 shows the airflow in the air-conditioned space generation system 1000. Air blown out from the air conditioner 100 is blown out downwards as an outlet flow 400 from the outlet 110 via the fan 240, duct 242, and line grille 244. The outlet flow 400 diffuses when it collides with the bottom surface 48. Since the space 60 is surrounded by the left surface 42 and the right surface 44, the outlet flow 400 that collides with the bottom surface 48 moves towards the center of the space 60. Near the center of the space 60, the outlet flow 400 blown out from the first outlet 110a and the outlet flow 400 blown out from the second outlet 110b collide and rise as an intake flow 402. The intake flow 402 is drawn into the first intake port 112a and the second intake port 112b. The air drawn in through the first intake port 112a and the second intake port 112b moves through the intake space 220 to the air conditioner 100. As a result, the air-conditioned space is formed by the flow of the discharge airflow 400 and the intake airflow 402 within the space 60.

[0055] Figures 15(a) and 15(b) show the simulation results for the air conditioning space generation system 1000. Figure 15(a) is a front view, and Figure 15(b) is a perspective view. The simulation conditions were: outside air temperature "35°C", outlet temperature "24°C", and airflow rate of 900 m³ with an outlet flow rate of 400. 3 The value is " / h". The same airflow as in Figure 14 is shown.

[0056] Figures 16(a)-(d) show the simulation results for the air-conditioned space generation system 1000. Figures 16(a)-(c) show the vertical temperature distribution at different locations. Figure 16(d) shows the color of the temperature distribution. Lighter colors indicate lower temperatures, and darker colors indicate higher temperatures. The simulation conditions here are the same as in Figures 15(a)-(b). In Figures 16(a)-(c), despite the outside air temperature being 35°C, an air-conditioned space of "30°C" or lower is uniformly formed inside space 60.

[0057] Figures 17(a)-(d) show the simulation results for the air-conditioned space generation system 1000. Figures 17(a)-(c) show the horizontal temperature distribution at different locations. Figure 17(d) shows the color of the temperature distribution. Lighter colors indicate lower temperatures, and darker colors indicate higher temperatures. The simulation conditions here are the same as in Figures 15(a)-(b). In Figures 17(a)-(c), even though the outside air temperature is 35°C, an air-conditioned space of "30°C" or lower is uniformly formed inside space 60.

[0058] In this embodiment, since the front vertical plate 36 is placed in the opening 50, the discharge flow 400 or suction flow 402 is less likely to leak out of the space 60. Also, since the discharge flow 400 or suction flow 402 is less likely to leak out of the space 60, energy efficiency can be improved. Furthermore, since the air conditioner 100, blower 240 and duct 242 are provided in the upper space 62, an air-conditioned space can be created in outdoor environments or indoor open spaces. In addition, since the bypass opening 212 connects the suction space 220 and the discharge space 222, an airflow greater than the airflow of the air conditioner 100 can be secured.
