[0026] FIG. 6 is a schematic diagram illustrating a portion of the temperature control device main body 40. As shown in FIG. 6, the housing 41 has a partition wall 41d that separates the interior of the main body 41c. The partition wall 41d divides the interior of the main body 41c in the front-to-rear direction X. By dividing the interior of the main body 41c by the partition wall 41d, the main body 41c is provided with a first storage section 41e and a second storage section 41f. The first storage section 41e and the second storage section 41f are arranged side by side in the front-to-rear direction X.

[0027] As shown in FIG. 5, the housing 41 has a first air outlet 61b. In the first embodiment, the first air outlet 61b is formed in the first duct portion 71. The first air outlet 61b is an opening on the lower side of the third extension portion 71c. In the first embodiment, the first air outlet 61b opens downward. The first air outlet 61b is rectangular. The shape of the first air outlet 61b is not particularly limited. The first air outlet 61b is located to the left (-Y side) of the main body portion 41c that houses the temperature adjustment unit 40a in the left-right direction Y. In the first embodiment, the left-right direction Y corresponds to a "second direction" perpendicular to the axial direction of the first rotation axis RA, with the left side corresponding to "one side of the second direction" and the right side corresponding to "the other side of the second direction." The first air outlet 61b is located forward (+X side) of the main body portion 41c.

[0028] At least a portion of the first air outlet 61b is located below the first rotor 33A. In the first embodiment, the entire first air outlet 61b is located below the first rotor 33A. At least a portion of the first air outlet 61b is located at a position overlapping the first rotor 33A when viewed in the vertical direction Z, which is the axial direction of the first rotation axis RA. In the present disclosure, "a certain object is located at a position overlapping the rotor 33 when viewed in the axial direction of the rotation axis R" means that, as shown in FIG. 3 , the certain object overlaps with the rotation region RE of the rotor 33 when viewed in the axial direction of the rotation axis R. The rotation region RE is the region inside the circular locus drawn by the outer edge of the rotor 33 in the radial direction centered on the rotation axis R when the rotor 33 rotates. At least a portion of the first air outlet 61b is located at a position overlapping with the rotation region RE of the first rotor 33A when viewed in the vertical direction Z.

[0029] In the first embodiment, the entire first air outlet 61b is disposed in a position overlapping with the first rotor 33A when viewed in the up-down direction Z, which is the axial direction of the first rotation axis RA. In other words, the entire first air outlet 61b is disposed in a position overlapping with the rotation region RE of the first rotor 33A when viewed in the up-down direction Z. The first air outlet 61b is disposed in a position overlapping with the first rotation axis RA of the first rotor 33A when viewed in the up-down direction Z.

The first air outlet 61b is located below the motor 32 of the first propulsion unit 31A.

[0030] The housing 41 has a second air outlet 62b. In the first embodiment, the second air outlet 62b is formed in the second duct portion 72. The second air outlet 62b is an opening on the upper side of the second extension portion 72b. In the first embodiment, the second air outlet 62b opens on the upper side. That is, in the first embodiment, the first air outlet 61b and the second air outlet 62b open in opposite directions. The second air outlet 62b is rectangular. The shape of the second air outlet 62b is not particularly limited. The second air outlet 62b is located rearward (toward the -X side) of the main body portion 41c.

[0031] The second air outlet 62b is located at a different position from the first rotor 33A when viewed in the vertical direction Z. In the present disclosure, "a certain object is located at a different position from the rotor 33 when viewed in the axial direction of the rotation axis R" means that the certain object is located at a position that does not overlap with the rotation region RE of the rotor 33 when viewed in the axial direction of the rotation axis R of the rotor 33. In the first embodiment, the second air outlet 62b is located at a different position from all the rotors 33 when viewed in the vertical direction Z. In other words, the second air outlet 62b is located at a position that does not overlap with the rotation region RE of all the rotors 33 when viewed in the vertical direction Z. The second air outlet 62b is located between the third rotor 33C and the fourth rotor 33D in the left-right direction Y when viewed in the vertical direction Z. As shown in FIG. 2 , the second air outlet 62b is located above the first rotor 33A. In the first embodiment, the second air outlet 62b is located above all the rotors 33.

[0032] The second air outlet 62b opens in a direction away from the flow of the air ARa sent by the first rotary blade 33A. That is, as shown in Fig. 1, the second air outlet 62b opens in a direction away from the blowing range AW of the air ARa sent by the first rotary blade 33A.

[0033] As shown in FIG. 3 , the first air outlet 61b and the second air outlet 62b are arranged on opposite sides of the center CL of the unmanned aerial vehicle 20 in the front-to-rear direction X. The center CL is the center of the unmanned aerial vehicle 20 in the front-to-rear direction X, and is also the center of the base 21 in the front-to-rear direction X. The first air outlet 61b is located forward (+X side) of the center CL. The second air outlet 62b is located rearward (-X side) of the center CL. In the first embodiment, the first air outlet 61b is located forward (+X side) of the main body 41c in the front-to-rear direction X. The second air outlet 62b is located rearward (-X side) of the main body 41c in the front-to-rear direction X. In the first embodiment, the front-to-rear direction X corresponds to a "first direction" perpendicular to the axial direction of the first rotation axis RA, with the front side corresponding to "one side of the first direction" and the rear side corresponding to "the other side of the first direction."

[0034] The temperature adjustment unit 40a shown in FIG. 6 adjusts the temperature of air. In the first embodiment, the temperature adjustment unit 40a is an air conditioner that adjusts the temperature of air using a refrigeration cycle. As shown in FIG. 6, the temperature adjustment unit 40a includes a first heat exchanger 42a, a second heat exchanger 42b, a first blower 43a, a second blower 43b, a compressor 44, a four-way valve 45, a flow control valve 46, and a refrigerant circuit unit 47. The first heat exchanger 42a and the first blower 43a are housed in the first housing unit 41e. The second heat exchanger 42b, the second blower 43b, the compressor 44, the four-way valve 45, and the flow control valve 46 are housed in the second housing unit 41f. The refrigerant circuit unit 47 is provided across the first housing unit 41e and the second housing unit 41f.

[0035] The temperature adjustment unit 40a can adjust the temperature of the air drawn into the housing 41 by performing heat exchange between the refrigerant 48 flowing through the refrigerant circuit unit 47 and the air drawn into the housing 41. Examples of the refrigerant 48 include a fluorine-based refrigerant or a hydrocarbon-based refrigerant with a low global warming potential (GWP). Examples of the refrigerant 48 include a single refrigerant selected from R1234yf, R1234ze, R32, and R290, a mixed refrigerant of two or more of these, or a mixed refrigerant of any of these with another refrigerant. Examples of the refrigerant 48 include a mixed refrigerant containing R1132(E) or a mixed refrigerant containing R1123. Examples of refrigerant 48 include mixed refrigerants of R516A, R445A, R444A, R454C, R444B, R454A, R455A, R457A, R459B, R452B, R454B, R447B, R447A, R446A, and R459A.

[0036] The first heat exchanger 42a, the second heat exchanger 42b, the compressor 44, the four-way valve 45, and the flow rate control valve 46 are provided in a refrigerant circuit section 47. The first heat exchanger 42a, the second heat exchanger 42b, the compressor 44, the four-way valve 45, and the flow rate control valve 46 are connected by the refrigerant circuit section 47. When the compressor 44 is driven, a refrigerant 48 circulates within the refrigerant circuit section 47.

[0037] The four-way valve 45 is provided in a portion of the refrigerant circuit unit 47 that is connected to the discharge side of the compressor 44. The four-way valve 45 switches some of the paths in the refrigerant circuit unit 47, thereby reversing the direction of the refrigerant 48 flowing through the refrigerant circuit unit 47. When the paths connected by the four-way valve 45 are the paths shown by solid lines on the four-way valve 45 in Fig. 6, the refrigerant 48 flows through the refrigerant circuit unit 47 in the direction shown by the solid arrows in Fig. 6. On the other hand, when the paths connected by the four-way valve 45 are the paths shown by dashed lines on the four-way valve 45 in Fig. 6, the refrigerant 48 flows through the refrigerant circuit unit 47 in the direction shown by the dashed arrows in Fig. 6.

[0038] The temperature adjustment unit 40a is capable of both cooling operation, which cools air, and heating operation, which warms air. When the temperature adjustment unit 40a is in cooling operation, the refrigerant 48 flowing through the refrigerant circuit unit 47 flows in the direction indicated by the solid arrows in Figure 6. That is, when the temperature adjustment unit 40a is in cooling operation, the refrigerant 48 flowing through the refrigerant circuit unit 47 circulates through the compressor 44, the second heat exchanger 42b, the flow control valve 46, and the first heat exchanger 42a, in that order, before returning to the compressor 44. In cooling operation, the first heat exchanger 42a functions as an evaporator, and the second heat exchanger 42b functions as a condenser.

[0039] On the other hand, when the temperature adjustment unit 40a is in heating operation, the refrigerant 48 flowing through the refrigerant circuit unit 47 flows in the direction shown by the dashed line in Fig. 6. In other words, when the temperature adjustment unit 40a is in heating operation, the refrigerant 48 flowing through the refrigerant circuit unit 47 circulates through the compressor 44, the first heat exchanger 42a, the flow control valve 46, and the second heat exchanger 42b in this order before returning to the compressor 44. In heating operation, the first heat exchanger 42a functions as a condenser, and the second heat exchanger 42b functions as an evaporator.

[0040] In the first embodiment, the first fan 43a is disposed inside the first housing 41e at a position facing the first air inlet 61a. The first fan 43a generates a flow of air AR1 that passes through the first heat exchanger 42a. When the first fan 43a is driven, outdoor air AR1 is drawn into the first housing 41e through the first air inlet 61a. That is, the air AR1 that passes through the first heat exchanger 42a is drawn into the first air inlet 61a. The air AR1 drawn into the first housing 41e passes through the first heat exchanger 42a. The air AR1 that passes through the first heat exchanger 42a is heat-adjusted to become temperature-adjusted air CA by exchanging heat with the refrigerant 48 flowing through the first heat exchanger 42a. As shown in Fig. 5, the temperature-controlled air CA flows from the first opening 41a into the first duct portion 71, passes through the first duct portion 71, and is blown out to the outdoors from the first air outlet 61b. As shown in Fig. 1, the temperature-controlled air CA blown out from the first air outlet 61b flows downward together with the air ARa sent downward by the first rotor 33A, and is supplied to the person WP and the area around the person WP. In this way, the temperature around the person WP is adjusted by the temperature-controlled air CA.

[0041] As shown in FIG. 6 , in the first embodiment, the second fan 43b is disposed inside the second housing 41f at a position facing the second air inlet 62a. The second fan 43b generates a flow of air AR2 that passes through the second heat exchanger 42b. When the second fan 43b is driven, outdoor air AR2 is drawn into the second housing 41f through the second air inlet 62a. That is, the air AR2 that passes through the second heat exchanger 42b is drawn into the second air inlet 62a. The air AR2 drawn into the second housing 41f passes through the second heat exchanger 42b. The air AR2 that passes through the second heat exchanger 42b exchanges heat with the refrigerant 48 flowing through the second heat exchanger 42b, thereby becoming exhaust air EA. As shown in FIG. 5, the exhaust air EA flows from the second opening 41b into the second duct portion 72, passes through the second duct portion 72, and is blown out to the outdoors from the second air outlet 62b.

[0042] As shown in FIG. 1 , in embodiment 1, the control device 80 is mounted on the temperature adjustment device 10. More specifically, the control device 80 is mounted on the unmanned air vehicle 20. The control device 80 is housed inside the base 21 of the unmanned air vehicle 20. The control device 80 controls the unmanned air vehicle 20 and the temperature adjustment unit 40a. As shown in FIG. 4 , the control device 80 is supplied with power from a first battery 51. The control device 80 supplies a portion of the power supplied from the first battery 51 to the power unit 30 and the imaging device 50.

[0043] The control device 80 controls the first fan 43 a and the second fan 43 b. In the first embodiment, the control device 80 can execute control to make the rotation speed of the first fan 43 a greater than the rotation speed of the second fan 43 b. This control causes the flow rate of the air blown out from the first air outlet 61 b, i.e., the temperature-controlled air CA, to be greater than the flow rate of the air blown out from the second air outlet 62 b, i.e., the exhaust air EA.

[0044] The control device 80 controls the power unit 30 to move the unmanned aerial vehicle 20. The control device 80 can move the unmanned aerial vehicle 20 in the forward / backward direction X, the left / right direction Y, and the up / down direction Z by controlling the rotation speed of each motor 32 in each propulsion unit 31. As shown in FIG. 1 , the control device 80 moves the unmanned aerial vehicle 20 to a position where it can supply temperature-controlled air CA to the target person WP based on information from the imaging device 50. More specifically, the control device 80 moves the unmanned aerial vehicle 20 to a position where the first rotor 33A is positioned directly above the target person WP. The control device 80 moves the unmanned aerial vehicle 20 in accordance with the movement of the person WP.

[0045] As shown in Figure 4, the control device 80 can communicate with the server 90 via a communication network NM, such as an IP (Internet Protocol) network. The control device 80 acquires information on at least one of wind speed and wind direction in the area in which the unmanned aerial vehicle 20 flies from the server 90. The control device 80 controls the position of the unmanned aerial vehicle 20 based on the information on at least one of wind speed and wind direction. In embodiment 1, the control device 80 acquires information on both wind speed and wind direction from the server 90 and controls the position of the unmanned aerial vehicle 20 based on the information on both wind speed and wind direction.

[0046] 7 is a flowchart showing an example of a control method in which the control device 80 controls the position of the unmanned aerial vehicle 20 based on wind speed and wind direction. As shown in FIG. 7, the control device 80 determines whether the wind speed is equal to or greater than a threshold value (step S1). If the wind speed is less than the threshold value (step S1: NO), the control device 80 moves the unmanned aerial vehicle 20 to a position where the first rotor 33A is positioned directly above the person WP, as shown in FIG. 1 (step S2). This allows temperature-controlled air CA to be supplied from directly above the person WP and the area around the person WP.

[0047] 7, if the wind speed is equal to or greater than the threshold (step S1: YES), the control device 80 determines the direction and movement amount ML of the unmanned aerial vehicle 20 based on the current position of the unmanned aerial vehicle 20 and the wind speed and direction (step S3). The control device 80 moves the unmanned aerial vehicle 20 based on the determined direction and movement amount ML (step S4).

[0048] FIG. 8 is a diagram showing an example in which the control device 80 controls the position of the unmanned aerial vehicle 20 when the wind speed is equal to or greater than a threshold. FIG. 8 shows an example in which the position of the unmanned aerial vehicle 20 is controlled by the control device 80 when the wind speed becomes equal to or greater than a threshold while the unmanned aerial vehicle 20 is in the position shown in FIG. 1 . In the example of FIG. 8 , the wind speed is α [m / s], which is equal to or greater than the threshold, and the wind direction is east. That is, in the example of FIG. 8 , the wind WD with a wind speed α [m / s] is blowing from east to west. Note that in the example of FIG. 8 , the front side (+X side) is east, and the rear side (-X side) is west. The control device 80 determines the direction in which to move the unmanned aerial vehicle 20 based on the wind direction. The control device 80 determines the direction in which to move the unmanned aerial vehicle 20 to be opposite to the direction in which the wind WD is flowing, i.e., upwind. For example, if the wind direction is east, the wind WD flows from east to west, and therefore the control device 80 determines the direction in which the unmanned aerial vehicle 20 should move to the east, i.e., forward (+X direction) in Figure 8. The control device 80 determines the movement amount ML by which the unmanned aerial vehicle 20 should move based on the magnitude of the wind speed. The control device 80 increases the movement amount ML by which the unmanned aerial vehicle 20 should move as the wind speed increases. The control device 80 determines the movement amount ML based on, for example, a predetermined data table.

[0049] In the example of Figure 8, the control device 80 moves the unmanned aerial vehicle 20 eastward by a distance ML from the position of the unmanned aerial vehicle 20 shown in Figure 1. In Figure 8, the imaginary line IL1 indicates the position of the first rotation axis RA of the first rotor 33A in Figure 1. In Figure 8, the imaginary line IL2 indicates the position of the first rotation axis RA of the first rotor 33A after the unmanned aerial vehicle 20 has moved based on wind speed and wind direction. When the wind speed is relatively high, the air ARa blown downward by the first rotor 33A may be blown by the wind WD, causing the air blowing range AW to bend downwind, resulting in the air ARa and the temperature-controlled air CA being removed from the person WP. In response to this, by moving the unmanned aerial vehicle 20 upwind in accordance with the magnitude of the wind speed, the position of the unmanned aerial vehicle 20 can be adjusted so that the person WP is within the air blowing range AW bent by the wind WD. This allows the temperature-controlled air CA to be suitably supplied to the person WP and the area around the person WP even when the wind WD is blowing at a speed equal to or greater than the threshold value.

[0050] According to the first embodiment, a temperature control device 10 capable of delivering temperature-adjusted air, i.e., temperature-controlled air CA, to a person WP includes a temperature control unit 40a that adjusts the temperature of air AR1, an unmanned aerial vehicle 20 equipped with the temperature control unit 40a, and a housing 41 that houses the temperature control unit 40a. The unmanned aerial vehicle 20 has a first rotor 33A that rotates about a first rotation axis RA. As the first rotor 33A rotates about the first rotation axis RA, air ARa is delivered to a first side, i.e., below, in the axial direction of the first rotation axis RA. The housing 41 has a first outlet 61b through which the temperature-controlled air CA, whose temperature has been adjusted by the temperature control unit 40a, is blown out. At least a portion of the first outlet 61b is positioned below the first rotor 33A and overlaps with the first rotor 33A when viewed in the axial direction, i.e., the vertical direction Z. Therefore, by utilizing the air ARa sent downward by the first rotor 33A, the temperature-controlled air CA blown out from the first air outlet 61b can be efficiently sent to the lower side of the first rotor 33A. As a result, by moving the unmanned aerial vehicle 20 to a position where the first rotor 33A is positioned above the person WP, the temperature-controlled air CA can be preferably sent to the person WP and the area around the person WP. Therefore, the temperature around the person WP can be preferably adjusted by the temperature-controlled air CA. Furthermore, even when the person WP is moving, by moving the unmanned aerial vehicle 20 in accordance with the person WP's movement, the temperature-controlled air CA can be sent to the moving person WP and the area around the person WP. Therefore, according to the first embodiment, the temperature control device 10 can adjust the temperature around the moving person WP.

[0051] For example, when a person WP works outdoors in the summer, there is a risk that the person WP may suffer from heatstroke. In response to this, by using the temperature adjustment device 10, cooled temperature-controlled air CA can be sent from above to the person WP and the area around the person WP outdoors. This prevents the person WP from suffering from heatstroke. Furthermore, because the temperature adjustment device 10 can fly above the person WP using the unmanned aerial vehicle 20, the person WP does not need to wear the temperature adjustment device 10. Therefore, the temperature adjustment device 10 can adjust the temperature around the person WP while preventing it from interfering with the work the person WP is doing.

[0052] Furthermore, since the temperature-controlled air CA can be sent using the air ARa sent by the first rotor 33A, it is easy to send the temperature-controlled air CA over long distances. This allows the unmanned aerial vehicle 20 to be kept sufficiently above the person WP while sending the temperature-controlled air CA to the person WP and the area around the person WP. This prevents the unmanned aerial vehicle 20 from coming into contact with the person WP. Furthermore, noise generated by the unmanned aerial vehicle 20 is less likely to reach the person WP, preventing the person WP from being bothered by the noise from the unmanned aerial vehicle 20.

[0053] Furthermore, by sending the temperature-controlled air CA together with the air ARa sent by the first rotor 33A, it is easy to supply the temperature-controlled air CA to the person WP and the area around the person WP without any waste. This makes it easy to adjust the temperature around the person WP in a short time. Therefore, it is easy to reduce the power consumption of the temperature control device 10, and the operating time of the temperature control device 10 can be extended.

[0054] Furthermore, according to the first embodiment, the first air outlet 61b opens downward. That is, the opening direction of the first air outlet 61b is the same as the direction in which the air ARa is sent by the first rotor 33A. Therefore, compared to when the first air outlet 61b faces horizontally, the temperature-controlled air CA blown out from the first air outlet 61b can be more easily sent downward together with the air ARa sent by the first rotor 33A. This makes it easier to send the temperature-controlled air CA to the person WP and the area around the person WP, thereby more effectively adjusting the temperature around the person WP.

[0055] Furthermore, according to the first embodiment, the housing 41 has a main body 41c that houses the temperature control unit 40a therein, and a first duct 71 that extends from the main body 41c. The first air outlet 61b is formed in the first duct 71. Therefore, by extending the first duct 71 to below the first rotor 33A, the first air outlet 61b can be easily disposed below the first rotor 33A.

[0056] Furthermore, according to the first embodiment, the temperature adjustment unit 40a includes a first heat exchanger 42a, a second heat exchanger 42b, a first fan 43a that generates a flow of air AR1 passing through the first heat exchanger 42a, and a second fan 43b that generates a flow of air AR2 passing through the second heat exchanger 42b, and adjusts the temperature of the air AR1 using a refrigeration cycle. The air AR1 that has passed through the first heat exchanger 42a, i.e., temperature-controlled air CA, is blown out from a first outlet 61b. The housing 41 includes a second outlet 62b from which the air AR2 that has passed through the second heat exchanger 42b, i.e., exhaust air EA, is blown out. Therefore, the temperature adjustment unit 40a can appropriately adjust the temperature of the air AR1 using the refrigeration cycle. Furthermore, the temperature adjustment unit 40a can both cool and warm the air AR1 by using the refrigeration cycle. Therefore, the temperature adjustment device 10 can suitably adjust the temperature around the person WP in both summer and winter.

[0057] Furthermore, according to the first embodiment, the second air outlet 62b opens in a direction away from the flow of the air ARa sent by the first rotor 33A. This prevents the exhaust air EA blown out from the second air outlet 62b from mixing with the air ARa sent by the first rotor 33A. This prevents the exhaust air EA from interfering with the temperature regulation around the person WP by the temperature-controlled air CA.

[0058] Furthermore, according to the first embodiment, the second air outlet 62b is disposed at a different position from the first rotor 33A when viewed in the vertical direction Z. This makes it possible to further prevent the exhaust air EA blown out from the second air outlet 62b from mixing with the air ARa sent by the first rotor 33A. This further prevents the exhaust air EA from interfering with the temperature regulation around the person WP by the temperature-controlled air CA.

[0059] Furthermore, according to the first embodiment, the first air outlet 61b and the second air outlet 62b open in opposite directions. This effectively prevents the exhaust air EA blown out from the second air outlet 62b from mixing with the air ARa sent by the first rotor 33A. This effectively prevents the exhaust air EA from interfering with the temperature-controlled air CA that regulates the temperature around the person WP. Furthermore, when the first air outlet 61b faces downward as in the first embodiment, the second air outlet 62b faces upward. This effectively prevents the exhaust air EA blown out from the second air outlet 62b from blowing upward away from the first rotor 33A. This effectively prevents the exhaust air EA from being sucked into the first rotor 33A and effectively prevents the exhaust air EA from mixing with the air ARa sent by the first rotor 33A.

[0060] Furthermore, according to the first embodiment, the second air outlet 62b is located above the first rotor 33A in the vertical direction Z. This makes it possible to further prevent the exhaust air EA blown out from the second air outlet 62b from mixing with the air ARa sent by the first rotor 33A.

[0061] Furthermore, according to the first embodiment, the temperature control device 10 controls the flow rate of the air blown out of the first air outlet 61b, i.e., the temperature-controlled air CA, to be greater than the flow rate of the air blown out of the second air outlet 62b, i.e., the exhaust air EA. This makes it easier to increase the flow rate of the temperature-controlled air CA, thereby more appropriately adjusting the temperature around the person WP. Furthermore, when the first air outlet 61b faces downward, the temperature-controlled air CA blown out downward can exert an upward reaction force on the unmanned aerial vehicle 20. This allows the output of the power unit 30, which generates buoyancy for the unmanned aerial vehicle 20, to be reduced by the amount of the reaction force generated by the temperature-controlled air CA. Specifically, the output of the motor 32 of each propulsion unit 31 can be reduced. This reduces the power consumption of the first battery 51, which supplies power to the unmanned aerial vehicle 20. This therefore extends the operating time of the unmanned aerial vehicle 20.

[0062] Furthermore, according to the first embodiment, the housing 41 has a second duct portion 72 extending from the main body portion 41c that houses the temperature control unit 40a. The second air outlet 62b is formed in the second duct portion 72. Therefore, the second duct portion 72 makes it easy to position the second air outlet 62b in a desired, suitable position.

[0063] Furthermore, according to the first embodiment, the first air outlet 61b is located on one side of the main body 41c of the housing 41, which houses the temperature adjustment unit 40a, in the front-rear direction X, which is perpendicular to the axial direction. The second air outlet 62b is located on the other side of the main body 41c, in the front-rear direction X, in the rear side (-X side). This makes it easy to arrange the first air outlet 61b and the second air outlet 62b at positions separated from each other. This more effectively prevents the temperature-controlled air CA blown out from the first air outlet 61b and the exhaust air EA blown out from the second air outlet 62b from mixing with each other.

[0064] Furthermore, according to the first embodiment, the housing 41 has a first inlet 61a through which air AR1 passing through the first heat exchanger 42a is drawn in, and a second inlet 62a through which air AR2 passing through the second heat exchanger 42b is drawn in. The first outlet 61b is located on one side of the main body 41c of the housing 41, which houses the temperature adjustment unit 40a, in the left-right direction Y, which is perpendicular to the axial direction. The first inlet 61a and the second inlet 62a are formed on the other side of the housing 41 in the left-right direction Y, in other words, on the right side (+Y side). Therefore, the first outlet 61b can be suitably spaced apart from the first inlet 61a and the second inlet 62a in the left-right direction Y. This prevents the temperature-controlled air CA blown out from the first outlet 61b from being drawn into the first inlet 61a and the second inlet 62a.

[0065] Furthermore, according to the first embodiment, the temperature adjustment system 100 includes a control device 80 capable of communicating with a server 90, and a temperature adjustment device 10. The control device 80 acquires information on at least one of wind speed and wind direction in the area in which the unmanned aerial vehicle 20 flies from the server 90, and controls the position of the unmanned aerial vehicle 20 based on the information on at least one of wind speed and wind direction. Therefore, as described above, even if the air ARa sent by the first rotor 33A is curved by the wind WD, the position of the unmanned aerial vehicle 20 can be adjusted according to at least one of the wind speed and wind direction of the wind WD. This prevents the air ARa sent by the first rotor 33A from deviating from the person WP, even when the wind WD is blowing, and allows the temperature-controlled air CA to continue to be preferably supplied to the person WP and the area around the person WP together with the air ARa.

[0066] Embodiment 2. Fig. 9 is a diagram showing a temperature adjustment system 200 according to embodiment 2. In the following description, the same components as those in the above-described embodiment may be denoted by the same reference numerals as appropriate, and the description thereof may be omitted.

[0067] As shown in Figure 9, the temperature adjustment system 200 includes a temperature adjustment device 210 and a control device 280. In the second embodiment, the unmanned air vehicle 220 in the temperature adjustment device 210 is equipped with a power control unit 224 instead of the control device 280. The power control unit 224 is capable of wireless communication with the control device 280. The power control unit 224 controls the power supplied to each unit of the temperature adjustment device 210 based on commands from the control device 280. The other configurations of the temperature adjustment device 210 are similar to the other configurations of the temperature adjustment device 10 in the first embodiment.

[0068] In the second embodiment, the control device 280 is a tablet terminal. The control device 280 is operated by, for example, an operator OP. The control device 280 sends a signal to the power control unit 224 based on information from the server 90, and controls the position of the unmanned air vehicle 220 in the temperature adjustment device 210, as in the first embodiment. The control device 280 may be capable of operating in a mode operated by the operator OP and a mode in which the control device 280 automatically operates the temperature adjustment device 210. The other configurations of the temperature adjustment system 200 are the same as the other configurations of the temperature adjustment system 100 in the first embodiment.

[0069] Embodiment 3. Fig. 10 is a diagram showing a temperature adjustment system 300 according to embodiment 3. In the following description, the same components as those in the above-described embodiments may be denoted by the same reference numerals as appropriate, and the description thereof may be omitted.

[0070] 10 , a temperature adjustment system 300 according to the third embodiment includes a temperature adjustment device 310 and a control device 80. The temperature adjustment device 310 includes a temperature adjustment device main body 340 and an unmanned air vehicle 20. In the housing 341 of the temperature adjustment device main body 340, the first duct section 371 has a third extension section 371c extending in a direction inclined obliquely in the front-rear direction X with respect to the up-down direction Z. The third extension section 371c is positioned closer to the front (+X side) as it extends downward.

[0071] The first air outlet 361b, which is provided at the tip end of the third extension portion 371c, i.e., at the lower and front end of the third extension portion 371c, opens in a direction inclined obliquely in the front-rear direction X with respect to the up-down direction Z. In the third embodiment, the first air outlet 361b opens downward and to the front (+X side). The inclination θ1 of the opening direction of the first air outlet 361b with respect to the up-down direction Z may be, for example, within a range of −90° to +90°, with a direction facing directly downward being defined as 0°. In other words, the first air outlet 361b may open in a direction parallel to the front-rear direction X and facing forward or rear (−X side), or may open in a direction facing downward and front or downward and rear.

[0072] In the second duct portion 372, the second extension portion 372b extends in a direction obliquely in the front-rear direction X with respect to the up-down direction Z. The second extension portion 372b is positioned rearward (negative X side) as it extends upward. The second air outlet 362b, which is provided at the tip end of the second extension portion 372b, i.e., at the upper and rear end of the second extension portion 372b, opens in a direction obliquely inclined in the front-rear direction X with respect to the up-down direction Z. In the third embodiment, the second air outlet 362b opens upward and rearward. The inclination θ2 of the opening direction of the second air outlet 362b with respect to the up-down direction Z may be, for example, within a range of −90° or more and +90° or less, with a direction facing directly upward being 0°. That is, the second air outlet 362b may open in a direction parallel to the front-rear direction X and facing the front (+X side) or rear, or may open in a direction opening both upward and forward, or upward and rear. The other configurations of the temperature adjustment system 300 are similar to the other configurations of the temperature adjustment system 100 in the first embodiment.

[0073] Embodiment 4. Fig. 11 is a diagram showing a temperature adjustment system 400 according to embodiment 4. In the following description, the same components as those in the above-described embodiments may be denoted by the same reference numerals as appropriate, and the description thereof may be omitted.

[0074] 11 , the temperature adjustment system 400 of embodiment 4 includes a temperature adjustment device 410 and a control device 80. The temperature adjustment device 410 includes a temperature adjustment device main body 440 and an unmanned air vehicle 20. In embodiment 4, the temperature adjustment device main body 440 does not include a first duct section 71. The front end (+X side) of the housing 441 of the temperature adjustment device main body 440 is located forward of the base 21 of the unmanned air vehicle 20.

[0075] A first air outlet 461b is formed at the front (+X side) end of the housing 441. In the fourth embodiment, the first air outlet 461b extends in the left-right direction Y. The first air outlet 461b opens to the front. At least a portion of the first air outlet 461b is located below the first rotor 33A and the second rotor 33B. In the fourth embodiment, the entire first air outlet 461b is located below the first rotor 33A and the second rotor 33B.

[0076] The first air outlet 461b has a portion that overlaps with the first rotor 33A when viewed in the axial direction of the first rotation axis RA, i.e., the vertical direction Z, and a portion that overlaps with the second rotor 33B when viewed in the vertical direction Z. In other words, the first air outlet 461b has a portion that overlaps with the rotation region RE of the first rotor 33A when viewed in the vertical direction Z, and a portion that overlaps with the rotation region RE of the second rotor 33B when viewed in the vertical direction Z. In the fourth embodiment, the left end (-Y side) of the first air outlet 461b overlaps with the first rotor 33A when viewed in the vertical direction Z. The right end (+Y side) of the first air outlet 461b overlaps with the second rotor 33B when viewed in the vertical direction Z. In the fourth embodiment, a portion of the first air outlet 461b excluding both ends in the horizontal direction Y does not overlap with any of the four rotors 33 when viewed in the vertical direction Z. In other words, the first air outlet 461b, excluding both ends in the left-right direction Y, is positioned at a different position from the four rotor blades 33 when viewed in the up-down direction Z.

[0077] The temperature control device 410 includes an airflow direction adjustment unit 470 that can adjust the direction of the air blown out from the first air outlet 461b, i.e., the temperature-controlled air CA. The airflow direction adjustment unit 470 is housed inside the housing 441. The airflow direction adjustment unit 470 has a plurality of blades 470a that are arranged at intervals in the left-right direction Y. The plurality of blades 470a are rotatable around an axis that extends in the up-down direction Z. The temperature-controlled air CA blown out from the first air outlet 461b is blown out along the plurality of blades 470a.

[0078] In the example of Fig. 11, the blades 470a are inclined to be positioned to the left (-Y side) as they move toward the front (+X side). Therefore, the temperature-controlled air CA blown out along the blades 470a is blown out toward the front and left (-Y side). As a result, the temperature-controlled air CA blown out from the first air outlet 461b flows toward a position below the first rotor 33A and overlapping with the first rotor 33A in the vertical direction Z. In other words, the temperature-controlled air CA blown out from the first air outlet 461b flows in a direction toward the flow of the air ARa sent downward by the first rotor 33A.

[0079] On the other hand, when the inclination of the blades 470a is such that they are positioned to the right (+Y side) as they move toward the front (+X side), the temperature-controlled air CA blown out along the blades 470a flows below the second rotor 33B and toward a position overlapping with the second rotor 33B in the up-down direction Z. In other words, the temperature-controlled air CA blown out from the first air outlet 461b flows in a direction toward the flow of air sent downward by the second rotor 33B.

[0080] As described above, by changing the inclination of the plurality of blades 470a, the airflow direction adjustment unit 470 can switch the direction of the temperature-controlled air CA blown out from the first air outlet 461b between a direction toward the flow of air ARa sent by the first rotor 33A and a direction toward the flow of air sent by the second rotor 33B. The other configurations of the temperature adjustment system 400 are similar to those of the temperature adjustment system 100 in the first embodiment.

[0081] According to the fourth embodiment, the temperature control device 410 includes an airflow direction adjustment unit 470 that can adjust the flow of the temperature-controlled air CA blown out from the first air outlet 461b. The unmanned aerial vehicle 20 has a second rotor 33B that rotates around a second rotation axis RB extending in the axial direction of the first rotation axis RA, i.e., in the up-down direction Z. At least a portion of the first air outlet 461b is located below the second rotor 33B. The first air outlet 461b has a portion that overlaps with the first rotor 33A when viewed in the up-down direction Z and a portion that overlaps with the second rotor 33B when viewed in the up-down direction Z. The airflow direction adjustment unit 470 can switch the direction of the temperature-controlled air CA blown out from the first air outlet 461b between a direction toward the flow of air ARa blown by the first rotor 33A and a direction toward the flow of air blown by the second rotor 33B. Therefore, the wind direction adjustment unit 470 can switch between supplying the temperature-controlled air CA blown out from the first air outlet 461b directly below the first rotor 33A and supplying the temperature-controlled air CA blown out from the first air outlet 461b directly below the second rotor 33B. This makes it easier to supply the temperature-controlled air CA to the person WP and the area around the person WP when the person WP moves, while reducing the amount of movement of the unmanned aerial vehicle 20. Therefore, the temperature around the moving person WP can be more appropriately adjusted. Furthermore, when two people WP are located directly below the first rotor 33A and two people WP are located directly below the second rotor 33B, the wind direction adjustment unit 470 can be adjusted to switch which person WP's surrounding temperature is adjusted.

The first direction perpendicular to the axial direction of the first rotation axis is not particularly limited. The second direction perpendicular to the axial direction of the first rotation axis is not particularly limited. The first direction and the second direction may be the same direction. As long as the unmanned aerial vehicle has the first rotor, it does not need to have any other rotors. The number of rotors provided on the unmanned aerial vehicle is not particularly limited, as long as it is one or more.

[0084] The first air outlet may be located at any position and may have any configuration as long as at least a portion of the first air outlet is located closer to the first rotor blade than the first rotor blade and overlaps the first rotor blade when viewed in the axial direction of the first rotation axis. The first air outlet may be configured like the first air outlet 161b shown by the two-dot chain line in FIG. 3.

The second air outlet may be located at any position. The second air outlet may be located at a position where it overlaps the first rotor blade or another rotor blade when viewed in the axial direction of the first rotation axis. The second air outlet may open in any direction. The flow rate of the air blown out from the first outlet may be the same as the flow rate of the air blown out from the second outlet, or may be less than the flow rate of the air blown out from the second outlet. The second outlet does not have to be formed.

[0085] The first and second suction ports may be provided anywhere on the housing. For example, in the first embodiment described above, one of the first and second suction ports 61a and 62a may be formed on the right side surface of the main body 41c, and the other may be formed on the left side surface of the main body 41c. In the first embodiment, the first and second suction ports 61a and 62a may be formed on the lower surface of the main body 41c.

In this case, the housing that houses the temperature adjustment unit is the housing of the unmanned air vehicle.

[0087] In the first embodiment described above, the first battery 51 that supplies power to the unmanned aerial vehicle 20 and the second battery 52 that supplies power to the temperature adjustment unit 40a are provided, but this is not limited to this. The temperature adjustment device may be provided with only one battery, and power may be supplied from this one battery to the unmanned aerial vehicle and the temperature adjustment unit.

[0088] The control device in the temperature control system may be provided in any manner as long as it can communicate with the server and control the temperature control device. At least a portion of the functions of the control device described in each of the above-mentioned embodiments are realized, for example, by a processor such as a CPU executing a program, i.e., software, stored in a storage unit (not shown). Note that at least a portion of the functions of each control device may be realized by hardware including circuit units such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), and a GPU (Graphics Processing Unit), or may be realized by a combination of software and hardware. The storage unit (not shown) is realized by a storage medium such as, for example, a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), a flash memory, etc. The storage unit (not shown) may be provided in the temperature adjustment system, or may be provided outside the temperature adjustment system and be able to communicate with the temperature adjustment system via wired or wireless communication.
