Description

[Technical Field]

[0001] The present disclosure relates to an air conditioning space generating system. [Background technology]

[0002] In order to efficiently cool and heat each work area within a factory, indoor units and human presence sensors are installed in each work area, and when the human presence sensor detects the presence of a person, the indoor units are operated in the order of detection (for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-175507 Summary of the Invention [Problem to be solved by the invention]

[0004] To improve the comfort of station users, it is desirable to air-condition the area around the chairs installed on the platform. For example, a waiting room can be installed around the chairs and the waiting room can be air-conditioned. However, if the size of the waiting room is large compared to the size of the platform, it is difficult to install the waiting room.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a technology for generating an air-conditioned space in an outdoor environment or an indoor open space. [Means for solving the problem]

[0006] To solve the above problems, an air-conditioning space generating system according to one embodiment of the present disclosure includes an upper hollow plate installed at a distance from a wall surface and extending laterally from a first end to a second end, a lower hollow plate installed below the upper hollow plate at a distance from the wall surface and extending laterally from the first end to the second end, and an upper deflector plate installed on the wall surface above the upper hollow plate. An upper opening is provided at the first end of the upper hollow plate, and the upper hollow plate has multiple upper fans on its upper rear surface facing the wall surface. An upward opening is provided between the upper hollow plate and the wall surface by sealing the gap between the upper rear surface and the wall surface downward, and the lower hollow plate has a lower opening at the first end, and the lower hollow plate has multiple lower fans on its lower rear surface facing the wall surface. Between the lower hollow plate and the wall surface, a downward opening is arranged by sealing the space between the lower rear surface and the wall surface upward. During heating operation, air is sucked into the lower hollow plate from the lower opening, and the plurality of lower fans blow the air in the lower hollow plate downward from the downward opening. The upper deflector causes the air that has risen toward the wall surface after being blown downward from the downward opening to descend, and the air that has been blown downward by the upper deflector is returned to the upward opening. During cooling operation, air is sucked into the upper hollow plate through the upper opening, and multiple upper fans blow the air in the upper hollow plate upward through the upward openings. The upper deflector directs the rising air toward the front, away from the wall surface, and the air that has been forced down toward the front by the upper deflector is sucked into the lower hollow plate through the downward opening, and the air in the upper hollow plate is blown out through the lower opening.

[0007] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc., are also valid aspects of the present disclosure. [Effects of the Invention]

[0008] According to the present disclosure, an air-conditioned space can be generated in an outdoor environment or an indoor open space. [Brief explanation of the drawings]

[0010] The examples described below each illustrate a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, component placement and connection configurations, steps (processes), and step order shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, components that are not described in the independent claims that represent the highest concept of the present disclosure are described as optional components. Furthermore, in each figure, substantially identical components are designated by the same reference numerals, and redundant descriptions are omitted or simplified.

[0011] 1(a)-(d) show the structure of the air-conditioned space generation system 2000. In particular, FIG. 1(a) is a perspective view showing the structure of the air-conditioned space generation system 2000. Here, the front, rear, left side, right side, upper side, and lower side in FIG. 1(a) are defined as the "front side," "rear side," "left side," "right side," "upper side," and "lower side," respectively. Furthermore, the direction connecting the front and rear sides is defined as the "front-to-rear direction," the direction connecting the left and right sides is defined as the "left-to-right direction," and the direction connecting the upper and lower sides is defined as the "up-to-down direction." These definitions are valid even if the orientation of the air-conditioned space generation system 2000 shown in other drawings is different. Based on these definitions, FIG. 1(b) is a front view of the air-conditioned space generation system 2000 when viewed from the front, and FIG. 1(c) is a top view of the air-conditioned space generation system 2000 when viewed from above.

[0012] A rectangular wall surface 2100 extending in the left-right and up-down directions is disposed at the rear of the air-conditioned space generating system 2000. The left end side of the wall surface 2100 is defined as a first end side P1, and the right end side of the wall surface 2100 is defined as a second end side P2. A seat panel 2104 extending in the front-rear and left-right directions is mounted on the wall surface 2100, and a backrest 2106 extending in the up-down and left-right directions is mounted on the wall surface 2100. The backrest 2106 is mounted above the seat panel 2104, and the combination of the seat panel 2104 and the backrest 2106 forms the shape of a bench on which a person can sit. The seat panel 2104 and the backrest 2106 extend in the left-right direction from the first end side P1 to the second end side P2.

[0013] An upper hollow plate 2140 is installed above the backrest 2106. The upper hollow plate 2140 is installed at a distance in front of the wall surface 2100. An upper deflection plate 2120 is installed above the upper hollow plate 2140. The upper deflection plate 2120 is installed on the wall surface 2100. Meanwhile, a lower hollow plate 2160 is installed below the seat plate 2104. The lower hollow plate 2160 is installed at a distance in front of the wall surface 2100. A lower deflection plate 2180 is installed below the lower hollow plate 2160. The lower deflection plate 2180 is installed on the wall surface 2100. Here, the upper deflection plate 2120, the upper hollow plate 2140, the lower hollow plate 2160, and the lower deflection plate 2180 all extend in the left-right direction from the first end side P1 to the second end side P2, and have a hollow structure.

[0014] A box-shaped air conditioning unit 2300 is disposed on a first end side P1 of the wall surface 2100, and a side wall 2500 is disposed on a second end side P2 of the wall surface 2100. By disposing the air conditioning unit 2300 in the left-right direction rather than the front-to-rear direction of the wall surface 2100, the length of the air conditioning space generation system 2000 in the front-to-rear direction, i.e., the depth of the air conditioning space generation system 2000, is narrowed. The box-shaped air conditioning unit 2300 has an air conditioning unit front face 2310 disposed on the front side, an air conditioning unit rear face 2312 disposed on the rear side, an air conditioning unit upper face 2314 disposed on the upper side, and an air conditioning unit lower face 2316 disposed on the lower side. Furthermore, the air conditioning unit 2300 has an air conditioning unit right face 2318 disposed on the right side and an air conditioning unit left face 2320 disposed on the left side. Each of the air conditioning unit front surface 2310, air conditioning unit rear surface 2312, air conditioning unit top surface 2314, air conditioning unit bottom surface 2316, air conditioning unit right side surface 2318, and air conditioning unit left side surface 2320 has a rectangular shape. The side wall 2500 is a rectangular surface that extends in the front-to-back and up-down directions.

[0015] An air conditioning unit front inlet 2332 is provided in the lower part of the air conditioning unit front surface 2310, an air conditioning unit rear inlet 2334 (not shown) is provided in the lower part of the air conditioning unit rear surface 2312, and an air conditioning unit outlet 2336 is provided in the air conditioning unit top surface 2314. The air conditioning unit front inlet 2332, the air conditioning unit rear inlet 2334, and the air conditioning unit outlet 2336 are all rectangular openings that connect the inside and outside of the air conditioning unit 2300.

[0016] Fig. 1(d) is a perspective view showing the surface of the air-conditioned space generating system 2000 in Fig. 1. The air conditioning unit 2300 has an outdoor unit 2400 and an indoor unit 2410 built in. The outdoor unit 2400 and the indoor unit 2410 are collectively referred to as air conditioners. Here, the outdoor unit 2400 and the indoor unit 2410 are arranged side by side in the vertical direction, with the outdoor unit 2400 being arranged below the indoor unit 2410. This arrangement of the outdoor unit 2400 and the indoor unit 2410 reduces the floor area of ​​the air conditioning unit 2300.

[0017] The surface of the upper deflection plate 2120 facing the wall surface 2100 is the upper rear surface 2144, and a plurality of upper fans 2146 are arranged in the left-right direction on the upper rear surface 2144. An upward opening 2200 that opens upward is formed between the upper rear surface 2144 and the wall surface 2100. The surface of the lower hollow plate 2160 facing the wall surface 2100 is the lower rear surface 2164, and a plurality of lower fans 2166 are arranged in the left-right direction on the lower rear surface 2164. A downward opening 2210 that opens downward is formed between the lower rear surface 2164 and the wall surface 2100. Here, the plurality of upper fans 2146 and the plurality of lower fans 2166 are bidirectional fans.

[0018] Such air-conditioned space generating system 2000 performs heating or cooling operation. In both heating and cooling operations, outdoor unit 2400 draws in outside air through air conditioning unit front inlet 2332 and air conditioning unit rear inlet 2334, and blows out inside air through air conditioning unit outlet 2336.

[0019] In heating operation, the indoor unit 2410 blows heated air at least into the lower hollow plate 2160, and the lower fan 2166 blows the air from the lower hollow plate 2160 to the outside. The upper fan 2146 draws outside air into the upper hollow plate 2140 and draws in air from at least the upper hollow plate 2140. As a result, the heated air is blown downward from the downward opening 2210, reflected by the lower deflection plate 2180, and moves forward. Furthermore, since the heated air has a light specific gravity, it rises, reflects off the upper deflection plate 2120, descends, and is drawn into the upward opening 2200. As a result, a heated space is formed around a person seated on the seat plate 2104 while leaning against the backrest 2106.

[0020] In cooling operation, the indoor unit 2410 blows cooled air at least to the upper hollow plate 2140, and the upper fan 2146 blows the air from the upper hollow plate 2140 to the outside. The lower fan 2166 draws outside air into the lower hollow plate 2160 and draws in air from at least the lower hollow plate 2160. As a result, the cooled air is blown upward from the upward opening 2200, reflected by the upper deflector plate 2120, and moves forward. Furthermore, since the cooled air has a high specific gravity, it descends, then reflects off the lower deflector plate 2180, rises, and is drawn into the downward opening 2210. As a result, an air-conditioned space is formed around a person seated on the seat plate 2104 while leaning against the backrest 2106. The heated space and the air-conditioned space are air-conditioned spaces (hereinafter referred to as "air-conditioned spaces").

[0021] Below, to explain the operation of air-conditioned space generating system 2000, FIGS. 2(a)-(c), 3(a)-(c), 4(a)-(c), 5(a)-(c), and 6(a)-(c) will also be used. FIGS. 2(a)-(c) show the operation of air-conditioned space generating system 2000. FIGS. 2(a)-(c) explain the operation of air intake from the outside to air-conditioning unit 2300 and the operation of air blowing from air-conditioning unit 2300 to the outside. FIG. 2(a) is a perspective view from the front of air-conditioned space generating system 2000, shown similarly to FIG. 1(a). FIG. 2(b) is a perspective view from the rear of air-conditioned space generating system 2000. FIG. 2(c) is a perspective view of the E-E cross section of FIG. 1(b).

[0022] The outdoor unit 2400 disposed in the air conditioning unit 2300 includes an outdoor unit inlet 2402 that draws in air and an outdoor unit outlet 2404 that blows out air. The outdoor unit inlet 2402 and the outdoor unit outlet 2404 are disposed on opposite sides. Specifically, the outdoor unit inlet 2402 is disposed in a space that communicates with the air conditioning unit front inlet 2332 and the air conditioning unit rear inlet 2334. The outdoor unit outlet 2404 is disposed in a space (hereinafter referred to as "blowout space 2340") that is isolated from the space that communicates with the air conditioning unit front inlet 2332 and the air conditioning unit rear inlet 2334. The outdoor unit outlet 2404 is communicated with the air conditioning unit outlet 2336.

[0023] The air conditioning unit front inlet 2332 and the air conditioning unit rear inlet 2334 draw outside air into the air conditioning unit 2300. The path of the drawn air is indicated as intake path 2600. The outdoor unit inlet 2402 draws in air drawn into the air conditioning unit 2300 (intake path 2600). The outdoor unit outlet 2404 blows the air into the outlet space 2340. The path of the blown air is indicated as outlet path 2602. The air in the outlet space 2340 (outlet path 2602) is blown out to the outside from the air conditioning unit outlet 2336. Because the outlet path 2602 faces upward from the air conditioning unit 2300, the air blown out along the intake path 2600 is prevented from hitting objects around the air-conditioned space generating system 2000 or users. This eliminates discomfort. The outdoor unit 2400 sends air to the indoor unit 2410, and the indoor unit 2410 sends air to the outdoor unit 2400. Known technologies may be used for these, and therefore a description thereof will be omitted here.

[0024] 3(a)-(c) show the operation of the heating operation in the air-conditioned space generating system 2000. In particular, FIG. 3(a) is a perspective view of the CC cross section of FIG. 1(c), FIG. 3(b) is a perspective view of the BB cross section of FIG. 1(b), and FIG. 3(c) is a perspective view of the AA cross section of FIG. 1(b).

[0025] The indoor unit 2410 in the air conditioning unit 2300 has an indoor unit inlet 2412 and an indoor unit outlet 2414. The indoor unit inlet 2412 is located on the right side surface of the air conditioning unit 2300. The indoor unit outlet 2414 is located above the indoor unit inlet 2412. Here, the indoor unit outlet 2414 faces right to blow out air during heating operation, and faces upward to blow out air during cooling operation. In Figure 3(a), the operation is during heating operation, which corresponds to the former.

[0026] Within the air conditioning unit 2300, the space connected to the indoor unit 2410 is divided into a lower space 2350 and an upper space 2352. During heating operation, the lower space 2350 is connected to the indoor unit air outlet 2414, and the upper space 2352 is connected to the indoor unit air inlet 2412. On the other hand, during cooling operation, the lower space 2350 is connected to the indoor unit air inlet 2412, and the upper space 2352 is connected to the indoor unit air outlet 2414. Figure 3(a) shows the former case, as it is during heating operation.

[0027] An upper opening 2142 is provided on the first end side P1 of the upper hollow plate 2140, and the internal space of the upper hollow plate 2140 communicates with the upper space 2352 via the upper opening 2142. Furthermore, an upper deflection plate opening 2122 is provided on the first end side P1 of the upper deflection plate 2120, and the internal space of the upper deflection plate 2120 communicates with the upper space 2352 via the upper deflection plate opening 2122. In this way, the indoor unit 2410 is connected to the upper opening 2142 and the upper deflection plate opening 2122.

[0028] As described above, the surface of the upper hollow plate 2140 that faces the wall surface 2100 is the upper rear surface 2144. On the upper rear surface 2144, multiple upper fans 2146 are arranged side by side in the left-right direction. The multiple upper fans 2146 are bidirectional fans that draw in air during heating operation and blow out air during cooling operation. For example, crossflow fans are used as the multiple upper fans 2146. Because crossflow fans have fewer swirling components than propeller fans, the uniformity of the wind speed distribution of the blown air is improved and speed components other than those in the vertical direction are suppressed.

[0029] A bottom is provided at the lower portion between the upper rear surface 2144 and the wall surface 2100. As a result, an upward opening 2200 that opens upward is arranged between the upper hollow plate 2140 and the wall surface 2100 by sealing the space between the upper rear surface 2144 and the wall surface 2100 downward. Air drawn in by the upper fan 2146 or air blown out from the upper fan 2146 passes through the upward opening 2200. Furthermore, a plurality of upper ribs 2202 that connect the upper rear surface 2144 and the wall surface 2100 are further provided at the upward opening 2200.

[0030] The inside of the side wall 2500 is divided into an upper space 2550 and a lower space 2552. The lower space 2552 is a space located below the upper space 2550. The lower space 2552 is provided to correspond to the lower space 2350, and the upper space 2550 is provided to correspond to the upper space 2352. An upper communication port 2148 is provided at the second end side P2 of the upper hollow plate 2140, and the internal space of the upper hollow plate 2140 and the upper space 2550 communicate with each other via the upper communication port 2148. In addition, an upper deflection plate communication port 2128 is provided at the second end side P2 of the upper deflection plate 2120, and the internal space of the upper deflection plate 2120 and the upper space 2550 communicate with each other via the upper deflection plate communication port 2128. As a result, the second end side P2 of the upper deflection plate 2120 and the second end side P2 of the upper hollow plate 2140 are in communication with each other.

[0031] A lower opening 2162 is provided on a first end side P1 of the lower hollow plate 2160, and the internal space of the lower hollow plate 2160 communicates with the lower space 2350 via the lower opening 2162. Furthermore, a lower deflection plate opening 2182 is provided on a first end side P1 of the lower deflection plate 2180, and the internal space of the lower deflection plate 2180 communicates with the lower space 2350 via the lower deflection plate opening 2182. In this way, the indoor unit 2410 is connected to the lower opening 2162 and the lower deflection plate opening 2182.

[0032] As described above, the surface of the lower hollow panel 2160 that faces the wall surface 2100 is the lower rear surface 2164. A plurality of lower fans 2166 are arranged side by side in the left-right direction on the lower rear surface 2164. The plurality of lower fans 2166 are bidirectional fans that blow out air during heating operation and draw in air during cooling operation. The plurality of lower fans 2166 may be, for example, cross-flow fans.

[0033] A ceiling portion is provided in the upper portion between the lower hollow plate 2160 and the wall surface 2100. As a result, a downward opening 2210 that opens downward is disposed between the lower hollow plate 2160 and the wall surface 2100 by sealing the space between the lower rear surface 2164 and the wall surface 2100 upward. Air drawn in by the lower fan 2166 or air blown out from the lower fan 2166 passes through the downward opening 2210. Furthermore, a plurality of lower ribs 2212 that connect the lower rear surface 2164 and the wall surface 2100 are further provided in the downward opening 2210.

[0034] A lower communication port 2168 is provided on the second end side P2 of the lower hollow plate 2160, and the internal space of the lower hollow plate 2160 communicates with the lower space 2552 via the lower communication port 2168. Furthermore, a lower deflection plate communication port 2188 is provided on the second end side P2 of the lower deflection plate 2180, and the internal space of the lower deflection plate 2180 communicates with the lower space 2552 via the lower deflection plate communication port 2188. This allows the second end side P2 of the lower hollow plate 2160 and the second end side P2 of the lower deflection plate 2180 to communicate with each other.

[0035] During heating operation, the indoor unit 2410 blows heated air from the indoor unit air outlet 2414 into the lower space 2350. The blown air travels through the lower space 2350 along a first heating path 2610. Within the lower space 2350, the first heating path 2610 branches into a second heating path 2612 and a third heating path 2614. The air traveling along the second heating path 2612 is drawn into the lower hollow plate 2160 through the lower opening 2162, and the air traveling along the third heating path 2614 is drawn into the lower deflector plate 2180 through the lower deflector plate opening 2182.

[0036] The air along the second heating path 2612 flows through the lower hollow plate 2160 in the direction from the first end P1 to the second end P2. On the other hand, the air along the third heating path 2614 flows through the lower deflection plate opening 2182 in the direction from the first end P1 to the second end P2 and is blown out of the lower deflection plate 2180 into the lower space 2552 at the lower deflection plate communication port 2188. The air along the third heating path 2614 flows through the lower space 2552 toward the lower communication port 2168 and is sucked into the lower hollow plate 2160 through the lower communication port 2168. The air along the third heating path 2614 also flows through the lower hollow plate 2160 in the direction from the second end P2 to the first end P1. Therefore, within the lower hollow plate 2160, air flowing along the second heating path 2612, which flows from the first end side P1 to the second end side P2, and air flowing along the third heating path 2614, which flows from the second end side P2 to the first end side P1, merge.

[0037] The multiple lower fans 2166 on the lower rear surface 2164 of the lower hollow plate 2160 blow air inside the lower hollow plate 2160 downward through the downward openings 2210. Here, the air along the second heating path 2612 and the air along the third heating path 2614 merge in the lower hollow plate 2160, improving the uniformity of the wind speed of the air blown out from the downward openings 2210. Furthermore, the lower ribs 2212 provided on the downward openings 2210 suppress the swirling component of the blown airflow during heating operation, improving the uniformity of the wind speed.

[0038] The lower deflector 2180 reflects the air blown downward from the downward opening 2210 toward the front. The air blown out from the downward opening 2210 travels along the fourth heating path 2616, descends from the downward opening 2210 to the lower deflector 2180, is reflected by the lower deflector 2180, and then rises toward the wall surface 2100 due to its light specific gravity. The upper deflector 2120 causes the air that has risen toward the wall surface 2100 to descend along the fourth heating path 2616. The air descending along the fourth heating path 2616 is sucked into the upper hollow plate 2140 through the upward opening 2200. At this time, the air passes through the upper ribs 2202 and is sucked into the upper hollow plate 2140 by the multiple upper fans 2146.

[0039] Figures 4(a)-(c) are continuations of Figures 3(a)-(c), and show the heating operation in the air-conditioned space generating system 2000. In particular, Figure 4(a) is a perspective view of the BB cross section of Figure 1(b), Figure 4(b) is a perspective view of the CC cross section of Figure 1(c), and Figure 4(c) is a perspective view of the DD cross section of Figure 1(c).

[0040] A portion of the air drawn into the upper hollow plate 2140 travels within the upper hollow plate 2140 along the fifth heating path 2618 toward the second end side P2 and is blown out from the upper hollow plate 2140 at the upper communication port 2148 into the upper space 2550. The air along the fifth heating path 2618 also travels through the upper space 2550 toward the upper deflection plate communication port 2128 and is drawn into the upper deflection plate 2120 from the upper deflection plate communication port 2128. The air along the fifth heating path 2618 also travels within the upper deflection plate 2120 from the second end side P2 to the first end side P1 and is blown out from the upper deflection plate opening 2122 into the upper space 2352. Meanwhile, the remainder of the air sucked into the upper hollow plate 2140 travels within the upper hollow plate 2140 along the sixth heating path 2620 toward the first end side P1 and is blown out from the upper hollow plate 2140 at the upper opening 2142 into the upper space 2352.

[0041] The air in the upper space 2352 flows along the seventh heating path 2622 toward the indoor unit inlet 2412 of the indoor unit 2410. At this time, the upper space 2550 and the lower space 2552 are separated by the attachment of a removable upper partition wall 2360. The outdoor unit 2400 draws the air along the seventh heating path 2622 from the indoor unit inlet 2412.

[0042] Figures 5(a)-(c) show the cooling operation of the air-conditioned space generating system 2000. In particular, Figure 5(a) is a perspective view of the CC cross section of Figure 1(c), Figure 5(b) is a perspective view of the BB cross section of Figure 1(b), and Figure 5(c) is a perspective view of the AA cross section of Figure 1(b). The following will mainly explain the differences from heating operation.

[0043] During cooling operation, the indoor unit 2410 blows cooled air from the indoor unit air outlet 2414 into the upper space 2352. The blown air travels through the upper space 2352 along a first cooling path 2640. Within the upper space 2352, the first cooling path 2640 branches into a second cooling path 2642 and a third cooling path 2644. The air traveling along the second cooling path 2642 is drawn into the upper hollow plate 2140 through the upper opening 2142, and the air traveling along the third cooling path 2644 is drawn into the upper deflector plate 2120 through the upper deflector plate opening 2122.

[0044] The air along the second cooling path 2642 flows within the upper hollow plate 2140 in the direction from the first end side P1 to the second end side P2. On the other hand, the air along the third cooling path 2644 flows within the upper deflector plate 2120 in the direction from the first end side P1 to the second end side P2, and is blown out from the lower deflector plate 2180 into the upper space 2550 at the upper deflector plate communication port 2128. Furthermore, the air along the third cooling path 2644 flows through the upper space 2550 toward the upper communication port 2148, and is sucked into the upper hollow plate 2140 from the upper communication port 2148. Furthermore, the air along the third cooling path 2644 flows within the upper hollow plate 2140 in the direction from the second end side P2 to the first end side P1. Therefore, within the upper hollow plate 2140, air flowing along the second air conditioning path 2642, which flows from the first end side P1 to the second end side P2, and air flowing along the third air conditioning path 2644, which flows from the second end side P2 to the first end side P1, merge.

[0045] The multiple upper fans 2146 on the upper rear surface 2144 of the upper hollow plate 2140 blow the air inside the upper hollow plate 2140 upward through the upward openings 2200. Here, the air along the second cooling path 2642 and the air along the third cooling path 2644 merge in the upper hollow plate 2140, improving the uniformity of the wind speed of the air blown out from the upward openings 2200. In addition, the upper ribs 2202 provided on the upward openings 2200 suppress the swirling component of the blown airflow during cooling operation, improving the uniformity of the wind speed.

[0046] The upper deflector 2120 reflects the air blown upward from the upward opening 2200 toward the front. The air blown out from the upward opening 2200 travels along the fourth cooling path 2646, rising from the upward opening 2200 to the upper deflector 2120, being reflected by the upper deflector 2120, and then descending. The lower deflector 2180 raises the air that has descended along the fourth cooling path 2646. The air ascending along the fourth cooling path 2646 is drawn into the lower hollow plate 2160 from the downward opening 2210. At this time, the air passes through the lower ribs 2212 and is drawn into the lower hollow plate 2160 by the multiple lower fans 2166.

[0047] Figures 6(a)-(c) are continuations of Figures 5(a)-(c), and show the cooling operation of the air-conditioned space generating system 2000. In particular, Figure 6(a) is a perspective view of the BB cross section of Figure 1(b), Figure 6(b) is a perspective view of the CC cross section of Figure 1(c), and Figure 6(c) is a perspective view of the DD cross section of Figure 1(c).

[0048] A portion of the air drawn into the lower hollow plate 2160 travels within the lower hollow plate 2160 along the fifth cooling path 2648 toward the second end side P2 and is blown out from the lower hollow plate 2160 at the lower communication port 2168 into the lower space 2552. The air along the fifth cooling path 2648 also travels through the lower space 2552 toward the lower deflector communication port 2188 and is drawn into the lower deflector plate 2180 from the lower deflector communication port 2188. The air along the fifth cooling path 2648 also travels within the lower deflector plate 2180 from the second end side P2 toward the first end side P1 and is blown out from the lower deflector plate opening 2182 into the lower space 2350. Meanwhile, the remainder of the air sucked into the lower hollow plate 2160 travels within the lower hollow plate 2160 along the sixth cooling path 2650 toward the first end side P1, and is blown out from the lower hollow plate 2160 at the lower opening 2162 into the lower space 2350.

[0049] The air in the lower space 2350 flows along the seventh cooling path 2652 toward the indoor unit inlet 2412 of the indoor unit 2410. At this time, the above-mentioned upper partition wall 2360 is removed and a removable lower partition wall 2362 is attached, thereby separating the upper space 2550 and the lower space 2552. The lower partition wall 2362 is removed during heating operation. The outdoor unit 2400 draws the air along the seventh cooling path 2652 from the indoor unit inlet 2412.

[0050] (Variation) (1) In the above description, the multiple upper fans 2146 and the multiple lower fans 2166 are bidirectional fans. However, this is not limiting, and for example, the multiple upper fans 2146 and the multiple lower fans 2166 may be unidirectional fans. A unidirectional fan operates in the direction of blowing out air. In heating operation, the multiple lower fans 2166 operate to blow out air from within the lower hollow plate 2160. Meanwhile, the multiple upper fans 2146 are stopped. In this case, air descending along the fourth heating path 2616 is sucked into the upper hollow plate 2140 through the openings in the multiple upper fans 2146. In cooling operation, the multiple upper fans 2146 operate to blow out air from within the upper hollow plate 2140. Meanwhile, the multiple lower fans 2166 are stopped. In this case, air rising along the fourth cooling path 2646 is sucked into the lower hollow plate 2160 through the openings in the multiple lower fans 2166 .

[0051] (2) In the description above, the upper deflection plate 2120 has the upper deflection plate opening 2122 and the upper deflection plate communication port 2128, and communicates with the upper space 2352 and the upper space 2550. However, the upper deflection plate 2120 may have a hollow structure that does not have the upper deflection plate opening 2122 or the upper deflection plate communication port 2128, and that separates the upper space 2352 and the upper space 2550.

[0052] In the above description, the lower deflector 2180 has the lower deflector opening 2182 and the lower deflector communication port 2188, and communicates with the lower space 2350 and the lower space 2552. However, the lower deflector 2180 may have a hollow structure that does not have the lower deflector opening 2182 and the lower deflector communication port 2188, and that separates the lower space 2350 from the lower space 2552. With such a structure, the amount of heat exchange between the blown airflow during heating operation and the suction airflow during cooling operation and the outside air is reduced by the air layer with high thermal insulation.

[0053] (3) The lower deflection plate 2180 may be a plate. The lower deflection plate 2180 serves as a heat insulator (for example, thermal conductivity less than 1.0 [W / (m / K)]), reducing the amount of heat exchange between the outlet airflow during heating operation and the intake airflow during cooling operation and the installation surface. In particular, during heating operation, if the temperature of the outlet airflow drops due to heat exchange, the density difference between the outlet airflow and the outside air becomes smaller, reducing the risk of not being able to form a zoning airflow (upward airflow).

[0054] (4) Figures 7(a)-(b) show the structure of the air-conditioned space generating system 2000. Figure 7(a) is similar to Figure 5(a). A dihedral portion 2190 is disposed at the front portion of the lower deflector plate 2180. The dihedral portion 2190 has a triangular prism shape and slopes upward toward the front. Figure 7(b) shows a cross-sectional view corresponding to Figure 7(a). Air along the fourth cooling path 2646 descends from the downward opening 2210 to the lower deflector plate 2180, moves forward along the lower deflector plate 2180, and then ascends along the slope of the dihedral portion 2190. The conditioned airflow during heating operation that flows along the lower deflector plate 2180 is also blown out through the dihedral portion 2190, thereby reducing the risk of the airflow flowing radially out of the device along the installation surface and failing to form a zoning airflow (upward airflow).

[0055] (5) Among the multiple upper fans 2146, the rotation speed of the upper fan 2146 on the second end side P2 may be higher than the rotation speed of the upper fan 2146 on the first end side P1. Also, among the multiple lower fans 2166, the rotation speed of the lower fan 2166 on the second end side P2 may be higher than the rotation speed of the lower fan 2166 on the first end side P1. The upper fans 2146 and the lower fans 2166 are collectively referred to as "fans." Because pressure loss is greater in the fans on the second end side P2 than in the fans on the first end side P1, increasing the rotation speed as described above reduces the difference in air volume among the multiple fans.

[0056] (6) Of the multiple upper fans 2146, the airflow of the upper fan 2146 on the second end side P2 may be greater than the airflow of the upper fan 2146 on the first end side P1. This means that the upper fan 2146 on the first end side P1 and the upper fan 2146 on the second end side P2 may be different types of fans with different performance, and this corresponds to using a high-performance upper fan 2146 with a large airflow and a low-performance upper fan 2146 with a small airflow.

[0057] Of the multiple lower fans 2166, the airflow of the lower fan 2166 on the second end side P2 may be greater than the airflow of the lower fan 2166 on the first end side P1. This means that the lower fan 2166 on the first end side P1 and the lower fan 2166 on the second end side P2 may be different types of fans with different performance, and this corresponds to using a high-performance lower fan 2166 with a large airflow and a low-performance lower fan 2166 with a small airflow. Because pressure loss is greater in the fan on the second end side P2 than in the fan on the first end side P1, increasing the airflow as described above reduces the difference in airflow among the multiple fans.

[0058] (7) The multiple upper fans 2146 may be propeller fans, and the multiple lower fans 2166 may also be propeller fans. FIGS. 8(a) and 8(b) show the operation of the upper fan 2146 and the lower fan 2166. FIG. 8(a) shows the first fan 2250a, the second fan 2250b, the third fan 2250c, and the fourth fan 2250d, which are used for comparison. The first fan 2250a, the second fan 2250b, the third fan 2250c, and the fourth fan 2250d are collectively referred to as fans 2250. The fans 2250 are arranged in the left-right direction, similar to the upper fan 2146 and the lower fan 2166 of this embodiment. The fans 2250 are propeller fans. Here, the first fan 2250a, the second fan 2250b, the third fan 2250c, and the fourth fan 2250d all rotate in the same direction. That is, the rotation directions of two adjacent fans 2250 are the same. In this case, the swirl components of the blown airflow are the same, so air is blown out in an inclined direction as shown in the figure.

[0059] FIG. 8(b) shows the operation of the upper fan 2146 or the lower fan 2166. The multiple upper fans 2146 are shown as, for example, a first upper fan 2146a, a second upper fan 2146b, a third upper fan 2146c, and a fourth upper fan 2146d. The upper fans 2146 are propeller fans. Here, the first upper fan 2146a and the third upper fan 2146c rotate counterclockwise, and the second upper fan 2146b and the fourth upper fan 2146d rotate clockwise. In other words, the rotation directions of two adjacent upper fans 2146 are different. Therefore, the swirl components of adjacent fans cancel each other out, suppressing the swirl component of the blown airflow during cooling operation. The same applies to the lower fan 2166.

[0060] According to this embodiment, during heating operation, air blown downward from the downward opening 2210 and then rising is forced down by the upper deflector 2120, and the descending air is sucked in through the upward opening 2200, thereby creating an air-conditioned space in an outdoor environment. Furthermore, during cooling operation, air blown upward from the upward opening 2200 is forced down toward the front by the upper deflector, and the air is sucked in through the downward opening 2210, thereby creating an air-conditioned space in an outdoor environment. Furthermore, since the upper fan 2146 and the multiple lower fans 2166 are bidirectional fans, air can be circulated efficiently in both heating and cooling operation. Furthermore, since the multiple upper fans 2146 and the multiple lower fans 2166 are unidirectional fans, control can be simplified. Here, air-conditioned spaces can be created not only in outdoor environments, but also in indoor open spaces, etc.

[0061] Furthermore, because the upper deflector 2120 has a hollow structure, the highly insulating air layer can reduce the amount of heat exchange between the blown airflow during heating operation and the suction airflow during cooling operation and the outside air. Also, because the amount of heat exchange between the blown airflow during heating operation and the suction airflow during cooling operation and the outside air is reduced, zoning performance can be improved. Furthermore, because the upper deflector 2120 and the upper hollow plate 2140 are in communication with each other, the upper deflector 2120 functions as a collision deflector for the blown airflow and is also utilized as an air path to the upper fan 2146 on the second end side P2, improving the wind speed uniformity of the blown airflow during cooling operation and the suction airflow during heating operation.

[0062] Furthermore, the lower deflector 2180 is further provided, which facilitates air circulation. The lower deflector 2180 has a hollow structure, which reduces the amount of heat exchange between the outlet airflow during heating operation and the intake airflow during cooling operation and the installation surface due to the highly insulating air layer. The lower deflector 2180 and the lower hollow plate 2160 communicate with each other, which is utilized as an air passage to the lower fan 2166 on the second end side P2, thereby improving the uniformity of the wind speed of the outlet airflow during heating operation and the intake airflow during cooling operation. Furthermore, because the lower deflector 2180 is a plate, if the temperature of the outlet airflow drops due to heat exchange during heating operation, the density difference between the outlet airflow and the outside air becomes smaller, which reduces the risk of the zoning airflow (upward airflow) not being able to form. Furthermore, since the lower deflection plate 2180 has the dihedral portion 2190, it is possible to reduce the risk of air flowing out of the device radially along the installation surface and failing to form a zoning air current (upward air current).

[0063] Furthermore, since the upward opening 2200 is provided with multiple upper ribs 2202, the swirling component of the blown airflow during cooling operation is suppressed, improving wind speed uniformity. Furthermore, since the downward opening 2210 is provided with multiple lower ribs 2212, the swirling component of the blown airflow during heating operation is suppressed, improving wind speed uniformity. Furthermore, since the multiple upper fans 2146 and the multiple lower fans 2166 are crossflow fans, they have fewer swirling components than propeller fans, improving the uniformity of the wind speed distribution at the outlet and suppressing velocity components other than in the vertical direction. Furthermore, since the multiple upper fans 2146 and the multiple lower fans 2166 have a higher rotation speed at the second end side P2 than at the first end side P1, differences in air volume can be suppressed. Furthermore, since the multiple upper fans 2146 and the multiple lower fans 2166 have a higher air volume at the second end side P2 than at the first end side P1, differences in air volume can be suppressed. Furthermore, the multiple upper fans 2146 and the multiple lower fans 2166 are all propeller fans, and the rotation directions of two adjacent fans are different, so the swirling components of the adjacent fans cancel each other out, thereby suppressing the swirling components of the airflow blown out during heating operation and the airflow blown out during cooling operation.

[0064] Furthermore, because the air conditioning unit 2300 is connected to the upper hollow board 2140 and the lower hollow board 2160, the air conditioning unit 2300 can be arranged to the side of the upper hollow board 2140 and the lower hollow board 2160. Furthermore, because the air conditioning unit 2300 is arranged to the side of the upper hollow board 2140 and the lower hollow board 2160, it is possible to narrow the depth of the air-conditioned space generation system 2000. Furthermore, because the depth of the air-conditioned space generation system 2000 is narrowed, the air-conditioned space generation system 2000 can be installed even in narrow areas.

[0065] Furthermore, because the outdoor unit 2400 and the indoor unit 2410 are built into the air conditioning unit 2300, it is possible to prevent the airflow (warm air during cooling operation, and cold air during heating operation) from the indoor unit 2410 from blowing onto users and the surrounding area. Furthermore, because the outdoor unit 2400 and the indoor unit 2410 are built into the air conditioning unit 2300, it is possible to prevent passersby from colliding with the outdoor unit 2400 and the indoor unit 2410. Furthermore, since passersby are not directly exposed to the airflow from the indoor unit 2410, discomfort factors can be eliminated. Furthermore, because the indoor unit 2410 and the outdoor unit 2400 are arranged side by side one above the other, the floor area of ​​the air conditioning unit 2300 can be reduced.
