Thereby, the air blown out in the centrifugal direction and the water droplets discharged in the centrifugal direction are mixed in the eliminator, and the air flowing through the eliminator can contain micronized water. Therefore, the humidifying performance of the humidifier can be improved, and the amount of humidification of the air in the air-conditioned room can be increased.

In addition, in the air conditioning system of the present invention, the lift pipe has a plurality of rotary plates arranged at predetermined intervals from each other in the axial direction of the rotating shaft and protruding from the outer peripheral surface of the lift pipe in the centrifugal direction. It is preferable that the Thereby, in the lift pipe, the pumped water can be discharged from the lift pipe in the centrifugal direction along the rotating plate, and can be reliably scattered as water droplets toward the eliminator.

Moreover, in the air conditioning system according to the present invention, it is preferable that the wind turbine is disposed vertically above the rotating plate so as to overlap with the water pump. As a result, the wind turbine and the rotary plate can be configured to be substantially integrated, so that the humidifier can be downsized. Therefore, in an air conditioning system using such a humidifier, the air conditioned room can be downsized.

Further, the living room 2d is provided with a circulation port 6d, a living room exhaust port 7d, a living room air supply port 8d, a living room temperature sensor 11d, and a living room humidity sensor 12d.

On the other hand, in the air-conditioned room 18, a transport fan 3a, a transport fan 3b, a damper 5a, a damper 5b, an air conditioner 13, a dust filter 17, and a humidifier 16 are installed. More specifically, from the upstream side of the air flow path flowing in the air conditioned room 18, the air conditioner 13, the dust filter 17, the humidifier 16, the conveyance fan 3 (conveyance fans 3a, 3b), the damper 5 (damper 5a, 5b), respectively.

In the air-conditioned room 18, the air (indoor air) conveyed from each living room 2 through the circulation port 6 and the outside air (outdoor air) taken in and heat exchanged by the heat exchange fan 4 are mixed. The temperature and humidity of the air in the air-conditioned room 18 are controlled by an air conditioner 13 and a humidifier 16 provided in the air-conditioned room 18, that is, the air is conditioned to generate air to be conveyed to the living room 2. The air conditioned in the air-conditioned room 18 is conveyed to each living room 2 by the conveyance fan 3. Here, the air-conditioned room 18 means a space with a certain size in which the air conditioner 13, humidifier 16, dust filter 17, etc. can be placed and where the air conditioning of each living room 2 can be controlled. It is not intended and does not basically mean a room where a resident stays.

The air in each living room 2 is transported to the air conditioning room 18 through the circulation port 6, and is also heat-exchanged through the heat exchange fan 4 through the living room exhaust port 7 before being discharged outdoors. The air conditioning system 20 performs type 1 ventilation by drawing outside air (outdoor air) into the room while exhausting inside air (indoor air) from each living room 2 using the heat exchange fan 4. The ventilation air volume of the heat exchange fan 4 is configured to be settable in multiple stages, and the ventilation air volume is set to satisfy the required ventilation volume stipulated by law.

The heat exchange fan 4 is configured to have an air supply fan and an exhaust fan (not shown) inside, and by operating each fan, the heat exchanger fan 4 creates a gap between inside air (indoor air) and outside air (outdoor air). Ventilate while exchanging heat. At this time, the heat exchange fan 4 conveys the heat-exchanged outside air to the air conditioning room 18.

The transport fan 3 is provided on the wall of the air conditioned room 18 (the wall on the bottom side). Then, the air in the air-conditioned room 18 is conveyed to the living room 2 from the living room air supply port 8 through the feeding duct by the feeding fan 3 . More specifically, the air in the air conditioned room 18 is transported by the transport fan 3a to a living room 2a and a living room 2b located on the first floor of the general residence 1, and is also transported by the transport fan 3b to the living room located on the second floor of the general residence 1. 2c and living room 2d. Note that the conveyance ducts connected to the living room air supply ports 8 of each living room 2 are provided independently.

When the damper 5 transports air from the transport fan 3 to each living room 2, the amount of air blown to each living room 2 is adjusted by adjusting the degree of opening of the damper 5. More specifically, the damper 5a adjusts the amount of air blown to the living room 2a and the living room 2b located on the first floor, and the damper 5b adjusts the amount of air blown to the living room 2c and the living room 2d located on the second floor.

A part of the air in each living room 2 (living room 2a to 2d) is transported to the air conditioned room 18 via a circulation duct by the corresponding circulation port 6 (circulation port 6a to 6d). Here, the air conveyed by the circulation port 6 is the amount of air conveyed from the air conditioning room 18 to each room 2 by the transfer fan 3 (air supply air amount), and the air is exhausted outdoors from the room exhaust port 7 by the heat exchange fan 4. The difference in air volume (exhaust air volume) is naturally transported to the air conditioned room 18 as circulating air. Note that the circulation ducts connecting the air-conditioned room 18 and each living room 2 may be provided independently, but a plurality of tributary ducts that are part of the circulation duct may be joined from the middle to form one circulation duct. After integration, it may be connected to the air conditioning room 18.

As described above, each circulation port 6 (circulation port 6a to 6d) is an opening for conveying indoor air from each living room 2 (living room 2a to 2d) to the air conditioned room 18.

Each living room exhaust port 7 (living room exhaust port 7a to 7d) is an opening for conveying indoor air from each living room 2 (living room 2a to 2d) to the heat exchange fan 4, as described above.

As described above, each living room air supply port 8 (residential room air supply port 8a to 8d) is an opening for conveying the air in the air conditioned room 18 from the air conditioned room 18 to each living room 2 (living room 2a to 2d).

The room temperature sensor 11 (room temperature sensor 11a to 11d) is a sensor that acquires the room temperature (indoor temperature) of each corresponding room 2 (room 2a to 2d) and transmits it to the system controller 14.

The living room humidity sensor 12 (the living room humidity sensor 12a to 12d) is a sensor that acquires the living room humidity (indoor humidity) of each of the corresponding living room 2 (the living room 2a to 2d) and transmits it to the system controller 14.

The air conditioner 13 corresponds to an air conditioner, and controls the air conditioning of the air conditioned room 18. The air conditioner 13 cools or heats the air in the air conditioned room 18 so that the temperature of the air in the air conditioned room 18 reaches a set temperature (air conditioned room target temperature). Here, the required heat amount is calculated from the temperature difference between the target temperature (occupied room target temperature) set by the user and the occupied room temperature, and the set temperature is set to a temperature based on the result.

The humidifier 16 is located on the downstream side of the air conditioner 13 in the air-conditioned room 18, and the humidity of the air in each living room 2 (room humidity) is lower than the target humidity (room target humidity) set by the user. In this case, the air in the air conditioned room 18 is humidified so that the humidity becomes the target humidity. Furthermore, although the humidity treated here is expressed as relative humidity, it may also be treated as absolute humidity through a predetermined conversion process. In this case, it is preferable that the entire operation of the air conditioning system 20, including the humidity of the living room 2, be treated as absolute humidity.

The dust filter 17 is a dust filter that collects particles floating in the air introduced into the air conditioned room 18. The dust filter 17 cleans the air supplied indoors by the transport fan 3 by collecting particles contained in the air transported into the air conditioned room 18 through the circulation port 6.

The system controller 14 is a controller that controls the entire air conditioning system 20. The system controller 14 is communicably connected to each of the heat exchange fan 4, the transfer fan 3, the damper 5, the room temperature sensor 11, the room humidity sensor 12, the air conditioner 13, and the humidifier 16 via wireless communication.

The system controller 14 also monitors the room temperature and room humidity of each room 2 acquired by the room temperature sensor 11 and the room humidity sensor 12, and the target temperature (room target temperature) and target temperature set for each room 2a to 2d. The air volume of the air conditioner 13 as an air conditioner, the humidifier 16, the transport fan 3, and the opening degree of the damper 5 are controlled according to the humidity (target humidity of the living room) and the like. Note that the air volume of the transport fan 3 may be controlled individually for each fan.

Thereby, the air conditioned in the air-conditioned room 18 is conveyed to each living room 2 at the air volume set for each conveyance fan 3 and each damper 5. Therefore, the living room temperature and living room humidity of each living room 2 are controlled to become the target temperature (living room target temperature) and the target humidity (living room target humidity).

Here, the system controller 14, the heat exchange fan 4, the transfer fan 3, the damper 5, the room temperature sensor 11, the room humidity sensor 12, the air conditioner 13, and the humidifier 16 are connected by wireless communication. Complex wiring work can be made unnecessary. However, all of these or a part of these with the system controller 14 may be configured to be communicable through wired communication.

The input/output terminal 19 is communicably connected to the system controller 14 by wireless communication, and accepts input of information necessary for constructing the air conditioning system 20 and stores it in the system controller 14, and inputs the status of the air conditioning system 20 into the system. It is acquired from the controller 14 and displayed. Examples of the input/output terminal 19 include portable information terminals such as mobile phones, smartphones, and tablets.

Note that the input/output terminal 19 does not necessarily need to be connected to the system controller 14 through wireless communication, and may be communicably connected to the system controller 14 through wired communication. In this case, the input/output terminal 19 may be realized by, for example, a wall-mounted remote controller.

Next, the configuration of the humidifying device 16 will be described with reference to FIG. 2. FIG. 2 is a schematic cross-sectional view of the humidifier 16 that constitutes the air conditioning system 20.

The humidifier 16 is located downstream of the air conditioner 13 in the air conditioner 18 and is a device for humidifying the air in the air conditioner 18 by centrifugal water crushing. As shown in FIG. 2, the humidifier 16 includes an inlet 31 that sucks air in the air-conditioned room 18, an outlet 32 that blows out humidified air into the air-conditioned room 18, and an air outlet 32 between the inlet 31 and the outlet 32. It includes an air path provided therein and a liquid atomization chamber 33 provided in this air path.

The suction port 31 is provided on the upper surface of the casing that constitutes the outer frame of the humidifier 16, and air (airflow) blown from the air conditioner 13 flows into the suction port 31. The air outlet 32 is provided on the side surface of the housing. The liquid atomization chamber 33 is the main part of the humidifier 16, and is where water is atomized using a centrifugal water crushing method.

Specifically, the humidifying device 16 includes a windmill 36, a rotating shaft 35 rotated by the windmill 36, a rotating motor 34 attached to the rotating shaft 35, a cylindrical water pump 37, a water storage section 40, and a rotary shaft 35 rotated by the windmill 36. It includes one eliminator 41 and a second eliminator 42.

The windmill 36 is a fan that is arranged vertically overlapping a water pump 37 (more precisely, a rotary plate 38), which will be described later, and is rotated by air flowing into the device from the air conditioner 18 (air conditioner 13). . The windmill 36 is fixed to the rotating shaft 35, and rotates the rotating shaft 35 in accordance with the rotation of the windmill 36, and introduces the air that has flowed into the device into the liquid atomization chamber 33. Furthermore, the windmill 36 is configured to rotate integrally with the water pump 37 via the rotating shaft 35. Details will be described later.

The rotating shaft 35 is a vertical axis that rotates in accordance with the rotation of the windmill 36. A water pump 37 is fixed to the rotary shaft 35 at a vertically lower portion of the shaft, and a rotary motor 34 is fixed at a vertically upper portion of the shaft. A windmill 36 is fixed to the rotating shaft 35 at a position sandwiched between the water pump 37 and the rotating motor 34 .

The rotary motor 34 is a motor that is attached so that the rotary shaft 35 can be rotated, and uses electric power to rotate the rotary shaft 35 or restrict the rotation of the rotary shaft 35. Then, the rotation motor 34 adjusts the rotation speed so that the rotation speed of the water pump 37 by the windmill 36 becomes the set rotation speed. More specifically, the rotary motor 34 rotates when the number of rotations of the water pump 37 caused by the windmill 36 is insufficient, based on information regarding the air volume (blow volume) of the air conditioner 13 included in the control signal from the system controller 14. It operates to increase the number of rotations, and when the number of rotations becomes excessive, it operates to decrease the number of rotations. In other words, the rotary motor 34 has a role of assisting the wind turbine 36 to rotate at an appropriate rotation speed.

The water pumping pipe 37 is fixed to the rotating shaft 35 inside the liquid atomization chamber 33, and rotates in accordance with the rotation of the windmill 36 (the rotating shaft 35), and pumps water from a circular water pumping port provided vertically downward. Pump up. More specifically, the pumping pipe 37 has a hollow structure in the shape of an inverted cone, and has a circular pumping port vertically downward. , a rotating shaft 35 arranged vertically is fixed. By connecting the rotating shaft 35 to a windmill 36 located vertically above the liquid atomization chamber 33, the rotational motion of the windmill 36 is transmitted to the water pumping pipe 37 through the rotating shaft 35, and the water pumping pipe 37 rotates.

The lift pipe 37 includes a plurality of rotary plates 38 formed on the top surface side of the inverted conical shape so as to protrude outward from the outer surface of the lift pipe 37. The plurality of rotary plates 38 are formed so as to protrude outward from the outer surface of the water lift pipe 37 with a predetermined interval provided between the rotary plates 38 that are vertically adjacent to each other in the axial direction of the rotary shaft 35 . Since the rotating plate 38 rotates together with the water pumping pipe 37, it is preferable that the rotating plate 38 has a horizontal disk shape coaxial with the rotating shaft 35. Note that the number of rotary plates 38 is appropriately set according to the target performance or the dimensions of the water pump 37.

Further, a plurality of openings 39 are provided in the wall surface of the water pumping pipe 37, which penetrate the wall surface of the water pumping pipe 37. Each of the plurality of openings 39 is provided at a position that communicates the inside of the water lift pipe 37 with the upper surface of the rotary plate 38 formed so as to protrude outward from the outer surface of the water lift pipe 37.

The water storage unit 40 is located vertically below the water pump 37 and stores water that the water pump 37 pumps from the water pumping port. The depth of the water storage section 40 is designed to be such that a part of the lower part of the pumping pipe 37, for example, about one-third to one-hundredth of the conical height of the pumping pipe 37, is immersed therein. . This depth can be designed according to the required pumping volume. Moreover, the bottom surface of the water storage part 40 is formed in a mortar shape toward the water pumping port. Water is supplied to the water storage section 40 by a water supply section (not shown).

The first eliminator 41 is a porous body through which air can flow, and is provided on the side of the liquid atomization chamber 33 (the outer periphery in the centrifugal direction), and is arranged so that air can flow in the centrifugal direction. In the first eliminator 41, the water droplets discharged from the opening 39 of the water pump 37 collide with each other to atomize the water droplets and collect water droplets from the water included in the air passing through the liquid atomization chamber 33. do. As a result, the air flowing through the humidifier 16 contains only vaporized water.

The second eliminator 42 is provided on the downstream side of the first eliminator 41 and is arranged so that air flows vertically upward. The first eliminator 41 is also a porous body through which air can flow, and when the air that has passed through the first eliminator 41 collides with it, it collects water droplets from the water contained in the air that has passed through the first eliminator 41. do. Thereby, by doubly collecting the miniaturized water droplets with the two eliminators, it is possible to collect water droplets with a large particle size with higher accuracy.

Next, with reference to FIGS. 3 and 4, the wind turbine 36 that constitutes the humidifier 16 will be described. FIG. 3 is a cross-sectional view of the wind turbine 36 and the water pump 37 that constitute the humidifying device 16. 4(a) is a top view of the windmill 36 that constitutes the humidifying device 16, and FIG. 4(b) is a sectional view of the fixed blade 36a of the windmill 36. Note that FIG. 4(b) shows a cross section taken along line AA in FIG. 4(a) when viewed from the outer circumferential side toward the rotating shaft 35 side.

As shown in FIG. 3, in the humidifier 16, air (airflow) from the air conditioner 13 flows into the liquid atomization chamber 33 from the suction port 31a communicating with the suction port 31 (see FIG. 2), and While colliding with the fixed blades 36a, the liquid flows toward the outer circumference along the rotating plate 36b. At this time, the air from the air conditioner 13 collides with the fixed blades 36a, so that a propulsive force (rotational force) is applied to the windmill 36, causing the windmill 36 to rotate.

Specifically, the windmill 36 includes a plurality of fixed blades 36a and a rotating plate 36b to which the plurality of fixed blades 36a are attached.

The rotating plate 36b has a substantially disk-like shape, and is connected to a first rotating plate portion 36b1 located on the rotating shaft 35 side and a second rotating plate portion 36b2 located on the outer peripheral side of the first rotating plate portion 36b1. It consists of The first rotary plate portion 36b1 is formed to have a horizontal disk shape, and the second rotary plate portion 36b2 has a gentle slope that descends from the horizontal position of the first rotary plate portion 36b1 toward the outer edge side. It is formed by In the rotary plate 36b, a plurality of fixed blades 36a are installed on the upper surface side of the first rotary plate portion 36b1.

The plurality of fixed blades 36a are members with which air (airflow) from the air conditioner 13 collides. As shown in FIG. 4A, the plurality of fixed blades 36a are provided radially on the upper surface side of the rotary plate 36b at equal intervals along the centrifugal direction with the rotary shaft 35 as the center. In this embodiment, ten fixed blades 36a are formed.

As shown in FIG. 4(b), each of the plurality of fixed blades 36a is located on the upstream side in the direction in which the upstream end P1 of the fixed blade 36a rotates with respect to the rotating shaft 35 (rotation direction) in its cross-sectional shape. However, since the downstream end P2 is located on the downstream side opposite to the direction of rotation with respect to the rotation shaft 35, it is inclined in the direction of rotation with respect to the rotation shaft 35.

In the wind turbine 36, since the fixed blades 36a are inclined, when air from the air conditioner 13 flows in from vertically upward (upstream side) and collides with the fixed blades 36a, the wind pressure of the air from the air conditioner 13 Since the force generates a force in the direction of rotation, the rotary plate 36b to which the fixed vane 36a is attached begins to rotate. In this way, the wind turbine 36 is rotated in the rotational direction (counterclockwise direction) by the air from the air conditioner 13 flowing in from upstream. Return to Figure 3.

The windmill 36 is fixed to the rotating shaft 35 via a housing tube 35a located on the outer periphery of the rotating shaft 35, as shown in FIG. A water pump 37 is connected to the rotating shaft 35 at a position vertically below the windmill 36 , and a rotary motor 34 is connected at a position vertically above the windmill 36 .

More specifically, as described above, a plurality of rotary plates 38 are connected to the lift pipe 37 at predetermined intervals so as to protrude outward from the outer surface of the lift pipe 37. On the other hand, the windmill 36 is configured to have fixed blades 36a on the upper surface of a rotating plate 36b, which generate a swirling flow when the windmill 36 rotates. In other words, the windmill 36 (rotary plate 36b of the windmill 36) is arranged vertically above the rotary plate 38 connected to the water pump 37 so as to be superimposed thereon.

As described above, the rotary plate 36b of the windmill 36 and the rotary plate 38 that constitutes the water pump 37 rotate together with the rotation of the rotary shaft 35, thereby rotating integrally.

Next, with reference to FIG. 2, the operating principle of humidification (water atomization) in the humidifier 16 will be explained. In addition, in FIG. 2, the flow of air and the flow of water within the apparatus are shown by arrows, respectively.

First, when the humidifier 16 starts operating, air from the air conditioner 13 flows in from the suction port 31 and collides with the fixed blades 36a of the windmill 36.The windmill 36 is rotated by being pushed by the air colliding with the fixed blades 36a. I come to do it. At this time, the restriction on the rotation of the rotating shaft 35 by the rotating motor 34 is released.

When the windmill 36 rotates the rotating shaft 35 at a first rotational speed R1 that is a set rotational speed, the water pump 37 rotates in accordance with this rotation. Here, the rotary motor 34 assists the rotation of the rotary shaft 35 by the windmill 36 as necessary to achieve the set rotation speed based on a control signal from the system controller 14. That is, as described above, the rotary motor 34 increases the rotation speed when the rotation speed of the water pump 37 caused by the wind turbine 36 is insufficient, based on the information regarding the air volume (blow volume) of the air conditioner 13, and If so, reduce the rotation speed. Then, the water stored in the water storage section 40 is pumped up by the water pump 37 due to the centrifugal force generated by the rotation of the windmill 36 (rotary shaft 35), as shown by the flow of water indicated by the broken line arrow. Here, the first rotation speed R1, which is the set rotation speed, is set, for example, between 2000 rpm and 5000 rpm, depending on the amount of air blown from the humidifier 16 and the amount of humidification of the air.

Since the water pumping pipe 37 has an inverted conical hollow structure, the water pumped up by rotation passes along the inner wall of the water pumping pipe 37 and is pumped upward. Then, the pumped water is discharged in the centrifugal direction from the opening 39 of the water pumping pipe 37 along the rotating plate 38, and is scattered as water droplets. The water droplets scattered from the rotary plate 38 fly through a space (liquid atomization chamber 33) surrounded by the first eliminator 41, collide with the first eliminator 41, and become atomized. On the other hand, the air passing through the liquid atomization chamber 33 via the windmill 36 contains water crushed (refined) by the first eliminator 41 as shown by the air flow indicated by the solid arrow. Move to the outer periphery. Then, in the process of the air flowing through the air path from the first eliminator 41 to the second eliminator 42, a vortex of airflow is generated and water and air mix. The air containing water then passes through the second eliminator 42. Thereby, the humidifier 16 can humidify the air sucked in through the suction port 31 and blow out the humidified air through the blowout port 32.

Note that the liquid to be atomized may be other than water, and may be, for example, a liquid such as hypochlorous acid water that has sterilizing or deodorizing properties.

As described above, according to the air conditioning system 20 according to the first embodiment, the following effects can be enjoyed.

(1) The air conditioning system 20 includes an air conditioning room 18 that is configured to introduce air from indoors and outdoors, an air conditioner 13 that is installed in the air conditioning room 18 and controls the temperature of the air in the air conditioning room 18, and an air conditioner 13 that is installed in the air conditioning room 18. A humidifying device 16 that humidifies air whose temperature has been controlled by an air conditioner 13, and a plurality of transport fans 3 that transport air in an air-conditioned room 18 to a plurality of indoor spaces independent of the air-conditioned room 18. The humidifying device 16 is arranged in a flow path through which air whose temperature is controlled by the air conditioner 13 flows into the device, and is fixed to a windmill 36 that is rotated by the air flowing into the device. A rotating shaft 35 that rotates with the rotation, and a cylinder that has a water pumping port vertically downward, is fixed to the rotating shaft 35, rotates together with the rotating shaft 35 to pump water from the pumping port, and discharges the pumped water in a centrifugal direction. A first eliminator 41 that atomizes the water by colliding with the water discharged from the water pump 37 and collects some of the micro water droplets; A water storage section 40 is provided vertically below the water pump and stores water pumped from the water pumping port.

According to this configuration, the wind turbine 36 receives wind pressure corresponding to the amount of air blown from the air conditioner 13 and rotates the rotary shaft 35, and the water pump 37 is rotated by the rotation of the rotary shaft 35. Energy consumption by the humidifying device 16 can be suppressed compared to a case where the rotary shaft is rotated by the power of a rotary motor as in the case of a humidifying device. Therefore, the energy efficiency of the humidifier 16 can be improved. In other words, the air conditioning system 20 using the humidifier 16 can contribute to energy saving.

(2) The air conditioning system 20 further includes a rotary motor 34 to which a rotary shaft 35 is rotatably attached. Then, the rotation motor 34 adjusts the rotation speed so that the rotation speed of the water pump 37 by the windmill 36 becomes the set rotation speed. As a result, even if variations occur in the amount of air blown from the air conditioner 13 (wind pressure), the rotation speed of the rotating shaft 35 is maintained at the set rotation speed, so the water pump 37 can be rotated at the set rotation speed. Can be done. Therefore, the humidifying ability of the humidifying device 16 can be stabilized.

(3) In the air conditioning system 20, the rotary motor 34 operates to increase the rotation speed when the rotation speed of the water pump 37 caused by the windmill 36 is insufficient, based on the information regarding the amount of air blown by the air conditioner 13. The number of rotations is now reduced when the number of rotations becomes excessive. As a result, even if variations occur in the amount of air blown from the air conditioner 13 (wind pressure), the rotational speed of the rotating shaft 35 can be maintained at the set rotational speed with higher precision using the minimum power of the rotary motor 34. be able to.

(4) In the air conditioning system 20, the windmill 36 has a plurality of fixed blades 36a provided along the centrifugal direction around the rotating shaft 35. The air was configured to blow out in the centrifugal direction toward the first eliminator 41 by hitting the fixed vane 36a. Thereby, the air blown out in the centrifugal direction and the water droplets released in the centrifugal direction are mixed in the first eliminator 41, and the air flowing through the first eliminator 41 is made to contain micronized water. Can be done. Therefore, the humidifying performance of the humidifier 16 can be improved, and the amount of humidification of the air in the air-conditioned room 18 can be increased.

(5) In the air conditioning system 20, the lift pipe 37 includes a plurality of rotary plates arranged at predetermined intervals in the axial direction of the rotating shaft 35 and protruding from the outer peripheral surface of the lift pipe 37 in the centrifugal direction. 38 was formed. Thereby, in the lift pipe 37, the pumped water can be discharged from the lift pipe 37 in the centrifugal direction along the rotating plate 38, and can be reliably scattered as water droplets toward the first eliminator 41.

(6) In the air conditioning system 20, the wind turbine 36 is arranged vertically above the rotating plate 38 and overlaps with the water pump 37. Thereby, the wind turbine 36 and the rotary plate 38 can be configured to be substantially integrated, so that the humidifier 16 can be downsized. Therefore, in the air conditioning system 20 using such a humidifier 16, the air conditioned room 18 can be downsized.

(7) In the air conditioning system 20, the rotation shaft 35 of the wind turbine 36 driven by the air (airflow) of the air conditioner 13 is shared with the water pump 37, so that the air from the air conditioner 13 flows in and the fixed blades of the wind turbine 36 36a is pushed by the inflowing air and generates force in the rotational direction so as to rotate. Thereby, the power consumption of the humidifier 16 is only that of the rotary motor 34 for stabilizing the rotation, so that the humidifier 16 can save energy.

(8) In the air conditioning system 20, the humidifying device 16 has a wind turbine 36 in the air path that introduces air whose temperature has been controlled by the air conditioner 13 into the device, and the air passing through the wind turbine 36 is pulverized by centrifugal crushing. The structure is such that the water is soaked in water and released. As a result, air is introduced into the humidifier 16 by the windmill 36, so the amount of humidification of the air in the air conditioner 18 can be adjusted without depending on the amount of air conveyed from the air conditioner 18 by the conveyor fan 3. .

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. This can be easily inferred. For example, the numerical values listed in the above embodiment are merely examples, and it is of course possible to employ other numerical values.

In the air conditioning system 20 according to the present embodiment, the rotary motor 34 is controlled so that the rotation of the wind turbine 36 reaches the target rotation speed based on the information regarding the air volume (air volume) of the air conditioner 13. However, the rotation motor 34 is not limited to this. I can't. For example, the rotary motor 34 may detect the rotation speed of the windmill 36 and control the rotation of the windmill 36 to a target rotation speed based on information regarding the detected rotation speed. Even in this case, similar effects can be obtained.

Further, in the air conditioning system 20 according to the present embodiment, an air conditioning room temperature sensor that detects the temperature of the air in the air conditioning room 18 may be provided in the air conditioning room 18. Thereby, the humidity control in the air-conditioned room 18 can be performed more accurately and reliably.

Further, in this embodiment, although the room is shown as a living room, the living room does not necessarily have to be occupied by a person and can be regarded as one space. In other words, if a hallway or kitchen is separated to some extent, it can be considered as one space, and falls under one living room.

Further, the air conditioning system 20 according to the present embodiment is applicable to a single-family house or a complex housing such as an apartment building. However, when the air conditioning system 20 is applied to a complex house, one system corresponds to each household, and each household does not have one room.
