Best Mode for Carrying Out the Invention

[0010] (Example 1) The examples described below 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 examples, 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 examples, the components not described in the independent claims indicating the most general 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 repeated explanations 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 exterior 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, although not limited thereto, has an air-conditioned space generated by the air-conditioned space generation system 1000 on the first floor. An eaves 20 is provided on one side of the box-shaped building 10, and the lower part of 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 on the upper part of the outer wall 24 along the outer wall 24 and in front 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 viewed from below for the parts 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 shape with an open front side.

[0013] On the rear portion of the top surface 46, the first outlet 110a, second outlet 110b, third outlet 110c, and fourth outlet 110d, collectively referred to as the air outlet 110, are arranged in order from the left side 42 to the right side 44. On the front portion of the top surface 46, the first suction port 112a, second suction port 112b, third suction port 112c, and fourth suction port 112d, collectively referred to as the suction port 112, are arranged in order from the left side 42 to the right side 44. In other words, on the top surface 46, the air outlets 110 and suction ports 112 are arranged in order from the rear side 40 to the opening 50. The number of air outlets 110 and the number of suction ports 112 are not limited to "4".

[0014] The first to fourth air outlets 110a to 110d blow conditioned air from the air conditioner 100 (not shown), described later, into the space 60. The first to fourth air inlets 112a to 112d draw air from the space 60 towards the air conditioner 100. In this embodiment, the air conditioning by the air conditioner 100 is assumed to be in heating operation. The airflow in the space 60 will be described later, but the air-conditioned space generation system 1000 generates an air-conditioned 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 lower position 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"). Known techniques can be used for temperature measurement by the outside air temperature sensor 102, so 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 heating 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 second exhaust port 120b, the third exhaust port 120c, and the fourth exhaust port 120d, collectively referred to as the exhaust port 120, are arranged in order from the left side 42 to the right side 44. Also on the interface 70, the first air intake port 122a, the second air intake port 122b, the third air intake port 122c, and the fourth air intake port 122d, collectively referred to as the air intake port 122, are arranged in order from the left side 42 to the right side 44. Here, the air intake port 122 is located above the exhaust port 120. The air conditioner 100 draws in air from the rear space 64, warms the drawn-in air, and then blows out the warmed air. For example, the air conditioner 100 draws in some air from the air intake port 122, warms the drawn-in air, and then blows out some of the warmed air to the exhaust port 120.

[0018] The upper space 62 houses the first to fourth line grilles 134a to 134d, collectively referred to as line grilles 134, the first to fourth supply air blowers 152a to 152d, collectively referred to as supply air blowers 152, and the control device 140. To illustrate these, Figures 4 and 5(a)-(b) are also used here.

[0019] Figure 4 is a front view of the air conditioning space generation system 1000. Figures 5(a) and 5(b) are cross-sectional perspective views of the air conditioning space generation system 1000. These are cross-sectional views of the CC section of Figure 4. As shown in Figure 5(a), the second line grille 134b has a hollow box shape and is installed on the rear and lower side of the upper space 62. The rear side of the second line grille 134b is open and communicates with the second exhaust port 120b. The lower side of the second line grille 134b is also open and communicates with the second air outlet 110b. Since the internal space of the second line grille 134b is the discharge space 162, the discharge space 162 forms an air passage in the upper space 62 connecting the second air outlet 110b and the second exhaust port 120b. The second exhaust fan 150b is installed in the second exhaust port 120b. The second exhaust fan 150b blows air from the second exhaust port 120b to the second outlet 110b within the discharge space 162. This airflow is shown as the discharge flow 400.

[0020] Furthermore, a discharge temperature sensor 104 is placed in the discharge space 162. The discharge temperature sensor 104 measures the temperature of the air supplied to the second discharge outlet 110b by the second supply air blower 152b (hereinafter referred to as "discharge temperature"). Since known techniques can be used for temperature measurement in the discharge temperature sensor 104, a detailed explanation is omitted here. The uses of the discharge temperature measured by the discharge temperature sensor 104 will be described later.

[0021] The first line grille 134a, the third line grille 134c, and the fourth line grille 134d in the upper space 62 are configured in the same way as the second line grille 134b. Therefore, the internal spaces of the first line grille 134a, the third line grille 134c, and the fourth line grille 134d are the discharge spaces 162. The first exhaust blowers 150a to the second exhaust blowers 150d are collectively referred to as exhaust blowers 150. On the other hand, the discharge temperature sensor 104 may or may not be placed in the first line grille 134a, the third line grille 134c, and the fourth line grille 134d.

[0022] As shown in Figure 5(b), the portion of the upper space 62 other than where the line grille 134 is located is shown as the intake space 160. An air inlet 122 is provided on the rear side of the intake space 160, and an air inlet 112 is provided on the lower side of the intake space 160. The intake space 160 forms an air passage connecting the air inlet 112 and the air inlet 122 in the upper space 62. A second air supply fan 152b is installed at the second air inlet 122b. The second air supply fan 152b blows air from the air inlet 112 to the second air inlet 122b within the intake space 160. This airflow is shown as the intake flow 402. Furthermore, the first air intake port 122a, the third air intake port 122c, and the fourth air intake port 122d are each equipped with a first air intake fan 152a (not shown), a third air intake fan 152c (not shown), and a fourth air intake fan 152d (not shown), respectively. The first air intake fans 152a to the fourth air intake fans 152d are collectively referred to as the air intake fan 152.

[0023] 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.

[0024] Figure 6 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 exhaust port 120 and line grille 134. The outlet flow 400 descends along the rear surface 40 due to the Coanda effect. When the outlet flow 400 collides with the lower surface 48, it flows towards the opening 50. At this time, the temperature and wind speed of the outlet flow 400 decrease. When the outlet flow 400 reaches near the opening 50, the wind speed of the outlet flow 400 is low and the temperature of the outlet flow 400 is high compared to the outside air temperature, so the outlet flow 400 rises as an intake flow 402. The intake flow 402 is drawn into the intake port 112. As a result, an air-conditioned space is formed as the outlet flow 400 and the intake flow 402 flow within the space 60.

[0025] 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 = Outlet temperature - Outside temperature

[0026] 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.

[0027] When the temperature difference is greater than the first threshold, it occurs when the outlet temperature rises above the standard state. The standard state is the average outside air temperature when heating operation is performed. In such situations, the outlet flow rate 400 tends to rise, and the air-conditioned space becomes narrower. In this embodiment, the airflow rate of the exhaust fan 150 is increased in order to increase the amount of intake flow rate 402. Also, when the temperature difference is greater than the first threshold, it occurs when the outside air temperature falls below the standard state. In such situations as well, the outlet flow rate 400 tends to rise, and the air-conditioned space becomes narrower. In this embodiment, the airflow rate of the exhaust fan 150 is increased in order to increase the amount of intake flow rate 402.

[0028] 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.

[0029] 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.

[0030] When the temperature difference is less than the second threshold, this occurs when the ambient temperature rises above the standard condition. In such a situation, the discharge flow rate 400 becomes less likely to rise, and the discharge flow rate 400 leaks out of the space 60. To reduce the amount of discharge flow rate 400, in this embodiment, the airflow rate of the exhaust fan 150 is reduced. Also, when the temperature difference is less than the second threshold, this occurs when the discharge temperature falls below the standard condition. In such a situation, the discharge flow rate 400 becomes less likely to rise, and the discharge flow rate 400 leaks out of the space 60. To reduce the amount of discharge flow rate 400, in this embodiment, the airflow rate of the exhaust fan 150 is reduced.

[0031] 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.

[0032] 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.

[0033] The operation of the air-conditioned space generation system 1000 with the above configuration will now be explained. Figure 7 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 outside air temperature from the discharge 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.

[0034] In this embodiment, since the outlet 110 and intake 112 are arranged sequentially on the upper surface 46 from the rear surface 40 toward the opening 50, an intake flow 402 can be generated based on the temperature difference between the outlet flow 400 and the ambient temperature near the opening 50. Furthermore, since the intake flow 402 is generated based on the temperature difference between the outlet flow 400 and the ambient temperature near the opening 50, an air-conditioned space can be created in outdoor environments or indoor open spaces. Also, since the intake flow 402 is generated based on the temperature difference between the outlet flow 400 and the ambient temperature near the opening 50, the intake 112 can draw in the intake flow 402. Furthermore, since the intake flow 402 is drawn in at the intake 112, energy efficiency can be improved.

[0035] Furthermore, since the airflow rate of the exhaust fan 150 is adjusted based on the outside air temperature and the discharge 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. Also, since the amount of suction flow 402 is increased, a uniform air-conditioned space can be created in space 60. Furthermore, since the differential temperature is calculated from the difference between the outside air temperature and the discharge temperature, and the airflow rate of the exhaust fan 150 is increased if the differential temperature is greater than the first threshold, and the airflow rate of the exhaust fan 150 is decreased if the differential temperature is less than the second threshold, the amount of suction flow 402 can be increased. Also, since the first threshold and the second threshold are equal, the amount of suction flow 402 can be increased. Furthermore, in the upper space 62, the outlet 110 and the exhaust port 120 are connected by the suction space 220, and the suction port 112 and the supply port 122 are connected by the discharge space 222, so the configuration can be simplified.

[0036] (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.

[0037] Figures 8(a) and 8(b) are perspective views of the air conditioning space generation system 1000. Figure 8(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 8(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, the first air outlet 110a to the fourth air outlet 110d are arranged in order from the left surface 42 to the right surface 44 on the rear part of the top surface 46. Furthermore, the front portion of the top surface 46 has the first suction port 112a to the fourth suction port 112d arranged in order from the left side 42 to the right side 44. The upper part of the front wall 30 is covered with a removable top cover 200.

[0038] Figures 9(a) and 9(b) are perspective views of the air conditioning space generation system 1000 with the top cover 200 removed. Figure 9(a) shows the view from above, and Figure 9(b) shows the view from the rear at an angle. The upper space 62 contains the air conditioner 100, the first blower 240a and second blower 240b collectively referred to as the blower 240, the first duct 242a and second duct 242b collectively referred to as the duct 242, and the first line grille 244a and second line grille 244b collectively referred to as the line grille 244.

[0039] The configuration of the upper space 62 will be described in detail below, using Figures 10(a)-(b) to 13. Figures 10(a)-(b) are the front and side views of the air conditioning space generation system 1000. Figures 11(a)-(c) are cross-sectional perspective views of the air conditioning space generation system 1000. These are cross-sectional views of Figure 10(a). The support plate 230 provided in the upper space 62 is a rectangular plate, and the support plate 230 divides the upper part of the upper space 62 into front and rear sections. A bypass opening 212 that penetrates from front to back is provided in the lower part of the support plate 230. The 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.

[0040] 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 in the upper space 62 between an intake space 220 connecting the first intake port 112a to the fourth intake port 112d and the air conditioning intake port 106 of the air conditioner 100, and an outlet space 222 including the air conditioning outlet 108 of the air conditioner 100, the first blower 240a and the second blower 240b. As shown in Figure 11(a), in the intake space 220, the airflow drawn in from 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.

[0041] As shown in Figure 11(b), the airflow (hereinafter referred to as "outlet flow 400") blown out from the air conditioning outlet 108 moves through the outlet space 222 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. Also, as shown in Figure 11(c), a portion of the suction flow 402 in the suction space 220 passes through the bypass opening 212 and enters the outlet space 222, where it moves through the outlet space 222 to the first blower 240a and the second blower 240b. The bypass opening 212 connects the suction space 220 and the outlet space 222 in the upper space 62. Here, the suction flow 402 that enters the outlet space 222 is mixed with the outlet flow 400. Therefore, this suction flow 402 is considered to be included in the discharge flow 400.

[0042] Figure 12 is a cross-sectional perspective view of the air conditioning space generation system 1000. This is a cross-sectional view of EE in Figure 10(a). This is shown similarly to Figure 11(c), where the suction flow 402 drawn in from the first intake port 112a moves to the discharge space 222 via the intake space 220 and the bypass opening 212.

[0043] Figure 13 is a cross-sectional perspective view of the air conditioning space generation system 1000. This is a cross-sectional view of the FF in Figure 10(b). Within the upper space 62, the first duct 242a is a hollow pipe 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 and the second outlet 110b. Therefore, an airflow path is formed from the first blower 240a through the first duct 242a, the first line grille 244a, the first outlet 110a, and the second outlet 110b. The airflow 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 and the second outlet 110b. An outlet temperature sensor 104 (not shown) is located in the first duct 242a.

[0044] Within the upper space 62, the second duct 242b is a hollow tube connecting the second blower 240b (not shown) and the second line grille 244b. The second line grille 244b has a hollow structure and is connected to the third outlet 110c and the fourth outlet 110d. Therefore, an airflow path is formed from the second blower 240b through the second duct 242b, the second line grille 244b, the third outlet 110c, and the fourth outlet 110d. The airflow 400 from the second blower 240b passes through the second duct 242b and the second line grille 244b and is blown out from the third outlet 110c and the fourth outlet 110d.

[0045] 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.

[0046] Figures 14(a) and 14(b) show the airflow in the air-conditioned space generation system 1000. Figure 14(a) is a perspective view, and Figure 14(b) is a side view. 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 descends along the building 10 and moves forward after hitting the bottom surface 48. Near the opening 50, the outlet flow 400 rises as an intake flow 402 due to the difference in temperature with the outside air outside the space 60 and the wind speed. The intake flow 402 is drawn into the intake port 112. The air drawn into the intake port 112 moves through the intake space 220 to the air conditioner 100. As a result, an air-conditioned space is formed by the flow of the outlet flow 400 and the intake flow 402 within the space 60.

[0047] Figures 15(a) and 15(b) show the simulation results for the air conditioning space generation system 1000. Figure 15(a) is a side view, and Figure 15(b) is a perspective view. The simulation conditions were an outside air temperature of 4°C, an outlet temperature of 25°C, and an airflow rate of 1000 m³ with an outlet flow rate of 400. 3 The value is " / h". The same airflow as in Figures 14(a)-(b) is shown.

[0048] 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), even though the outside air temperature is 5°C, an air-conditioned space of "15°C" or higher is uniformly formed inside space 60.

[0049] 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 5°C, an air-conditioned space of "15°C" or higher is uniformly formed inside space 60.

[0050] In this embodiment, since the upper space 62 is equipped with an air conditioner 100, a blower 240, and a duct 242, an air-conditioned space can be created in outdoor environments or indoor open spaces. Furthermore, since the bypass opening 212 connects the intake space 220 and the discharge space 222, an airflow greater than that of the air conditioner 100 can be secured.
