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 rooms 2a to 2d) is conveyed to the air conditioning room 18 through the circulation duct by the corresponding circulation ports 6 (circulation ports 6a to 6d). Here, the air conveyed by the circulation port 6 is exhausted to the outside from the living room exhaust port 7 by the heat exchange air fan 4 and the air volume (supply air amount) conveyed from the air conditioning room 18 to each living room 2 by the transport fan 3. Only the difference in the air volume (exhaust air volume) is naturally transported to the air conditioning chamber 18 as circulating air. The circulation ducts connecting the air conditioning chamber 18 and each living room 2 may be provided independently, but a plurality of tributary ducts that are a part of the circulation ducts are merged from the middle into one circulation duct. After the integration, it may be connected to the air conditioning chamber 18.

The air conditioner 13 cools or heats the air in the air conditioning chamber 18 so that the temperature of the air in the air conditioning chamber 18 becomes the set temperature (target temperature in the air conditioning chamber). Here, the set temperature is set to a temperature based on the result of calculating the required heat amount from the temperature difference between the target temperature (living room target temperature) set by the user and the living room temperature.

The humidifying device 16 is located on the downstream side of the air conditioner 13 in the air conditioning chamber 18, and the humidity of the air in each living room 2 (living room humidity) is lower than the target humidity set by the user (living room target humidity).

The air volume of the transport fan 3 may be controlled individually for each fan.

As a result, the air conditioned in the air-conditioned room 18 is transported to each living room 2 with the air volume set in each transport fan 3 and each damper 5. Therefore, the living room temperature and the living room humidity of each living room 2 are controlled to be the target temperature (living room target temperature) and the target humidity (living room target humidity).

The wind turbine 36 is a fan that is superposed on the pumping pipe 37 (more accurately, the rotating plate 38) described later in the vertical direction and is rotated by the air flowing into the apparatus from the air conditioning chamber 18 (air conditioner 13). .. The wind turbine 36 is fixed to the rotary shaft 35, rotates the rotary shaft 35 in accordance with the rotation of the wind turbine 36, and introduces the air flowing into the apparatus into the liquid miniaturization chamber 33. Further, the wind turbine 36 is configured to rotate integrally with the pumping pipe 37 via the rotating shaft 35. Details will be described later.

The rotation shaft 35 is a shaft along the vertical direction that rotates in accordance with the rotation of the wind turbine 36. A pumping pipe 37 is fixed to the rotary shaft 35 in the vertical direction of the shaft, and a rotary motor 34 is fixed in the vertical direction of the shaft. The wind turbine 36 is fixed to the rotary shaft 35 at a position sandwiched between the pumping pipe 37 and the rotary motor 34.

The rotary motor 34 is a motor to which the rotary shaft 35 is rotatably attached, and the rotary shaft 35 is rotated by electric power or the rotation of the rotary shaft 35 is restricted. Then, the rotary motor 34 adjusts the rotation speed so that the rotation speed of the pumping pipe 37 by the wind turbine 36 becomes the set rotation speed. More specifically, the rotary motor 34 rotates when the rotation speed of the pumping pipe 37 by the wind turbine 36 is insufficient based on the information regarding the air volume (air flow rate) of the air conditioner 13 included in the control signal from the system controller 14. It operates to increase the number of revolutions, and operates to decrease the number of revolutions when the number of revolutions becomes excessive. That is, the rotary motor 34 has a role of assisting the rotation of the wind turbine 36 to have an appropriate rotation speed.

By connecting the rotary shaft 35 to the wind turbine 36 located vertically above the liquid miniaturization chamber 33, the rotational motion of the wind turbine 36 is conducted to the pumping pipe 37 through the rotating shaft 35, and the pumping pipe 37 rotates.

The pumping pipe 37 is provided with a plurality of rotating plates 38 formed so as to project outward from the outer surface of the pumping pipe 37 on the top surface side of the inverted cone. The plurality of rotating plates 38 are formed so as to project outward from the outer surface of the pumping pipe 37 with a predetermined interval in the axial direction of the rotating shaft 35 between the rotating plates 38 adjacent to each other on the upper and lower sides. Since the rotary plate 38 rotates together with the pumping pipe 37, a horizontal disk shape coaxial with the rotary shaft 35 is preferable. The number of rotating plates 38 is appropriately set according to the target performance or the dimensions of the pumping pipe 37.

Further, the wall surface of the pumping pipe 37 is provided with a plurality of openings 39 penetrating the wall surface of the pumping pipe 37. Each of the plurality of openings 39 is provided at a position communicating the inside of the pumping pipe 37 and the upper surface of the rotating plate 38 formed so as to project outward from the outer surface of the pumping pipe 37.

The water storage unit 40 stores the water pumped by the pumping pipe 37 from the pumping port below the vertical direction of the pumping pipe 37. The depth of the water storage portion 40 is designed so that a part of the lower part of the pumping pipe 37, for example, about one-third to one-hundredth of the height of the cone of the pumping pipe 37 is immersed. .. This depth can be designed according to the required pumping volume. Further, the bottom surface of the water storage unit 40 is formed in a mortar shape toward the pumping port.

In the first eliminator 41, the water droplets discharged from the opening 39 of the pumping pipe 37 collide with each other to make the water droplets finer, and at the same time, collect the water droplets among the water contained in the air passing through the liquid miniaturization chamber 33. do. As a result, the air flowing in the humidifying device 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 can flow upward in the vertical direction. The first eliminator 41 is also a porous body through which air can flow, and when the air passing through the first eliminator 41 collides with the first eliminator 41, water droplets among the water contained in the air passing through the first eliminator 41 are collected. do. As a result, the finely divided water droplets are doubly collected by the two eliminators, so that the water droplets having a large particle size can be collected more accurately.

Next, the wind turbine 36 constituting the humidifying device 16 will be described with reference to FIGS. 3 and 4. FIG. 3 is a cross-sectional view of the wind turbine 36 and the pumping pipe 37 constituting the humidifying device 16. FIG. 4A is a top view of the wind turbine 36 constituting the humidifying device 16, and FIG. 4B is a cross-sectional view of the fixed blade 36a of the wind turbine 36. Note that FIG. 4B shows a state in which the cross section of FIG. 4A along the line AA is viewed from the outer peripheral side to the rotation shaft 35 side.

As shown in FIG. 3, in the humidifying device 16, the air (air flow) from the air conditioner 13 flows into the liquid miniaturization chamber 33 from the suction port 31a communicating with the suction port 31 (see FIG. 2), and the wind turbine 36 While colliding with the fixed blade 36a of the above, the air flows toward the outer periphery along the rotating plate 36b. At this time, when the air from the air conditioner 13 collides with the fixed blades 36a, a propulsive force (rotational force) is applied to the wind turbine 36, and the wind turbine 36 rotates.

Specifically, the wind turbine 36 includes a plurality of fixed blades 36a and a rotary plate 36b to which the plurality of fixed blades 36a are attached.

The rotary plate 36b has a substantially disk-like shape, and is connected to the first rotary plate portion 36b1 located on the rotary shaft 35 side and the second rotary plate portion 36b2 located on the outer peripheral side of the first rotary plate portion 36b1. It is composed of. The first rotating plate portion 36b1 is formed having a horizontal disk shape, and the second rotating plate portion 36b2 has a gently inclined surface that descends from the horizontal position of the first rotating plate portion 36b1 toward the outer edge side. Is formed. In the rotary plate 36b, a plurality of fixing 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 the air (air flow) from the air conditioner 13 collides. As shown in FIG. 4A, the plurality of fixing blades 36a are provided radially on the upper surface side of the rotating plate 36b along the centrifugal direction with the rotation axis 35 as the center at equal intervals. In this embodiment, 10 fixed blades 36a are formed.

As shown in FIG. 4B, each of the plurality of fixed blades 36a is located on the upstream side in the direction (rotational direction) in which the upstream end P1 of the fixed blades 36a rotates with respect to the rotation axis 35. The downstream end P2 is located on the downstream side opposite to the direction of rotation with respect to the rotation shaft 35, so that the downstream end P2 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 the air from the air conditioner 13 flows in from above (upstream side) in the vertical direction and collides with the fixed blades 36a, the air pressure from the air conditioner 13 causes the air pressure. Since the force generates a force in the rotation direction, the rotary plate 36b to which the fixing blades 36a are attached starts to rotate. In this way, the wind turbine 36 is rotated in the rotation direction (counterclockwise direction) by the air from the air conditioner 13 flowing in from the upstream. Return to FIG.

As shown in FIG. 3, the wind turbine 36 is fixed to the rotating shaft 35 via a housing pipe 35a located on the outer periphery of the rotating shaft 35. A pumping pipe 37 is connected to the rotary shaft 35 in the vertical direction of the wind turbine 36, and a rotary motor 34 is connected to the rotary shaft 35 in the vertical direction of the wind turbine 36.

More specifically, as described above, a plurality of rotating plates 38 are connected to the pumping pipe 37 at predetermined intervals so as to project outward from the outer surface of the pumping pipe 37. On the other hand, the wind turbine 36 is configured to have a fixed blade 36a on the upper surface of the rotary plate 36b to generate a swirling flow when the wind turbine 36 rotates. That is, the wind turbine 36 (rotating plate 36b of the wind turbine 36) is arranged so as to be superimposed on the vertical direction of the rotating plate 38 connected to the pumping pipe 37.

As described above, the rotary plate 36b of the wind turbine 36 and the rotary plate 38 constituting the pumping pipe 37 rotate in accordance with the rotation of the rotary shaft 35, so that they rotate integrally.

Next, with reference to FIG. 2, the operating principle of humidification (miniaturization of water) in the humidifying device 16 will be described. In FIG. 2, the flow of air and the flow of water in the device are indicated by arrows.

First, when the operation of the humidifying device 16 is started, the air of the air conditioner 13 flows in from the suction port 31, collides with the fixed blades 36a of the wind turbine 36, is pushed by the air colliding with the fixed blades 36a, and the wind turbine 36 rotates. Will come to do. At this time, the rotation restriction of the rotating shaft 35 by the rotating motor 34 is released.

Then, when the rotation shaft 35 is rotated at the first rotation speed R1 which is the set rotation speed of the wind turbine 36, the pumping pipe 37 rotates in accordance with this rotation. Here, the rotary motor 34 assists the rotation of the rotary shaft 35 by the wind turbine 36 as necessary so as to reach the set rotation speed by the 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 pumping pipe 37 by the wind turbine 36 is insufficient based on the information regarding the air volume (air flow amount) of the air conditioner 13, and the rotation speed becomes excessive. If, the number of revolutions is reduced. Then, like the flow of water indicated by the broken arrow, the water stored in the water storage unit 40 is pumped up by the pumping pipe 37 by the centrifugal force generated by the rotation of the wind turbine 36 (rotating shaft 35). Here, the first rotation speed R1, which is the set rotation speed, is set between 2000 rpm and 5000 rpm, for example, depending on the amount of air blown from the humidifying device 16 and the amount of humidification to the air.

Since the pumping pipe 37 has an inverted conical hollow structure, the water pumped up by rotation is pumped upward along the inner wall of the pumping pipe 37. Then, the pumped water is discharged in the centrifugal direction from the opening 39 of the pumping pipe 37 through the rotating plate 38, and is scattered as water droplets. The water droplets scattered from the rotating plate 38 fly in the space (liquid miniaturization chamber 33) surrounded by the first eliminator 41, collide with the first eliminator 41, and are miniaturized. On the other hand, the air passing through the liquid miniaturization chamber 33 via the wind turbine 36 contains the water crushed (miniaturized) by the first eliminator 41 as shown by the solid arrow, and the first eliminator 41. Move to the outer periphery of. Then, in the process of air flowing in the air passage from the first eliminator 41 to the second eliminator 42, a vortex of the air flow is generated, and water and air are mixed. Then, the air containing water passes through the second eliminator 42. As a result, the humidifying device 16 can humidify the air sucked from the suction port 31 and blow out the humidified air from the outlet 32.

The liquid to be refined may be other than water, and may be, for example, a liquid such as hypochlorite water having bactericidal or deodorant properties.

Then, the rotary motor 34 adjusts the rotation speed so that the rotation speed of the pumping pipe 37 by the wind turbine 36 becomes the set rotation speed. As a result, even if the amount of air blown (wind pressure) from the air conditioner 13 varies, the rotation speed of the rotating shaft 35 is maintained at the set rotation speed, so that the pumping pipe 37 is rotated at the set rotation speed. Can be done. Therefore, the humidifying capacity 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 pumping pipe 37 by the wind turbine 36 is insufficient, based on the information regarding the air flow amount of the air conditioner 13. It works to reduce the number of revolutions when the number becomes excessive. As a result, even if the amount of air blown (wind pressure) from the air conditioner 13 varies, the rotation speed of the rotation shaft 35 is maintained at the set rotation speed with higher accuracy by the minimum power of the rotation motor 34. be able to.

The air was configured to blow out in the centrifugal direction toward the first eliminator 41 by hitting the fixed blade 36a. As a result, the air blown out in the centrifugal direction and the water droplets discharged in the centrifugal direction are mixed in the first eliminator 41, and the air flowing through the first eliminator 41 is contained with finely divided water. Can be done. Therefore, the humidifying performance of the humidifying device 16 can be improved, and the amount of humidifying the air in the air conditioning chamber 18 can be increased.

(5) In the air conditioning system 20, a plurality of rotary plates are arranged on the pumping pipe 37 at predetermined intervals in the axial direction of the rotary shaft 35, and are formed so as to project in the centrifugal direction from the outer peripheral surface of the pumping pipe 37. 38 was formed. As a result, in the pumping pipe 37, the pumped water can be discharged from the pumping pipe 37 in the centrifugal direction through the rotating plate 38 and surely scattered as water droplets toward the first eliminator 41.

(6) In the air conditioning system 20, the wind turbine 36 is arranged so as to be superimposed on the pumping pipe 37 above the rotating plate 38 in the vertical direction. As a result, the wind turbine 36 and the rotating plate 38 can be substantially integrated, so that the humidifying device 16 can be miniaturized. Therefore, in the air conditioning system 20 using such a humidifying device 16, the air conditioning chamber 18 can be miniaturized.

(7) In the air conditioning system 20, the rotating shaft 35 of the windmill 36 driven by the air (air flow) of the air conditioner 13 is shared with the pumping pipe 37, so that the air from the air conditioner 13 flows in and the fixed blades of the windmill 36 are fixed. The 36a was pushed by the inflowing air to generate a force in the rotation direction to rotate. As a result, the power consumption used as the humidifying device 16 only uses the power consumption of the rotary motor 34 for stabilizing the rotation, so that the energy saving of the humidifying device 16 can be realized.
