Description

Air conditioning system

This disclosure relates to an air conditioning system that air-conditions multiple spaces.

Conventionally, an air conditioning system that air-conditions a house with an air conditioner in the entire building is known. In addition, it is expected that the number of highly insulated and airtight houses will increase with the increase in demand for energy-saving houses and the tightening of regulations, and there is a demand for air conditioning systems suitable for these characteristics.

As such an air-conditioning system, the air transported from a plurality of spaces or the like to the air-conditioning room is air-conditioned to a predetermined temperature and humidity in the air-conditioning room so that the temperature and humidity of the air in the plurality of spaces (living rooms) become the target temperature and humidity. Then, there is known a whole-building air-conditioning system that transports air to each of a plurality of spaces (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2020-6389

In the conventional whole building air conditioning system, the temperature of the air in the air conditioning room is controlled by the air conditioner (air conditioning conditioner) installed in the air conditioning room, and the humidity of the air in the air conditioning room is controlled by the humidifying device installed in the air conditioning room. is doing. Then, the space in the air-conditioning room is divided, and temperature control and humidification control are efficiently performed in each space.

However, in the conventional whole building air conditioning system, the air volume is generated by the humidifying device separately from the air volume for controlling the temperature with the air conditioner to humidify. Generally, the air volume of an air conditioner is large, and it has more power than the air volume for air conditioning a living room. However, the humidifier is generally equipped with a small fan. For this reason, the humidifying device in the conventional air-conditioning system in the entire building has a problem that the air volume is not sufficient and the energy efficiency is poor.

The present disclosure provides an air conditioning system using a humidifying device that can contribute to energy saving.

The air-conditioning system according to the present disclosure is installed in an air-conditioning room configured to allow air to be introduced from indoors and outdoors, an air-conditioner installed in the air-conditioning room to control the temperature of the air in the air-conditioning room, and an air-conditioning room installed in the air-conditioning room. It is equipped with a humidifying device that humidifies the temperature-controlled air and a transport fan that transports the air in the air-conditioned room to an indoor space different from the air-conditioned room. The humidifier is arranged in a flow path where the air temperature controlled by the air conditioner flows into the humidifier, and is fixed to the windmill and the windmill that rotates with the rotation of the windmill. From the tubular pumping pipe and the pumping pipe, which are fixed to the shaft and the rotating shaft and rotate with the rotating shaft to pump water from the pumping port provided below in the vertical direction and discharge the pumped water in the centrifugal direction. When the discharged water collides, the collided water is refined and a part of the atomized water is collected. It is configured to have a water storage unit that stores water.

According to the present disclosure, it is possible to provide an air conditioning system using a humidifying device that can contribute to energy saving.

FIG. 1 is a schematic connection diagram of an air conditioning system according to the first embodiment of the present disclosure. FIG. 2 is a schematic cross-sectional view of a humidifying device constituting the air conditioning system. FIG. 3 is a cross-sectional view of a wind turbine and a pumping pipe constituting the humidifying device. FIG. 4A is a top view of the wind turbine constituting the humidifying device. FIG. 4B is a cross-sectional view of the fixed blade of the wind turbine.

According to such a configuration, the wind turbine receives the wind pressure according to the amount of air blown from the air conditioner to rotate the rotating shaft, and the rotation of the rotating shaft causes the pumping pipe to rotate. Therefore, energy consumption by the humidifying device can be suppressed as compared with the case where the rotating shaft is rotated by the power of the rotating motor as in the conventional humidifying device. Therefore, the energy efficiency of the humidifier can be improved. That is, it is possible to make an air conditioning system using a humidifying device that can contribute to energy saving.

Further, the air conditioning system according to the present disclosure may further include a rotary motor rotatably attached to the rotary shaft. The rotary motor may adjust the rotation speed of the rotating shaft so that the rotation speed of the pumping pipe by the wind turbine becomes the set rotation speed.

As a result, even if the amount of air blown from the air conditioner (wind pressure) varies, the rotation speed of the rotating shaft is maintained at the set rotation speed. Therefore, the pumping pipe can be rotated at a set rotation speed. Therefore, the humidifying capacity of the humidifying device can be stabilized.

Further, in the air conditioning system according to the present disclosure, the rotary motor operates so as to increase the rotation speed of the rotating shaft when the rotation speed of the pumping pipe is insufficient, based on the information regarding the air volume of the air conditioner. When the rotation speed of the pumping pipe becomes excessive, the operation may be performed so as to reduce the rotation speed of the rotation shaft.

By doing so, even if the amount of air blown from the air conditioner (wind pressure) varies, the rotation speed of the rotating shaft can be maintained at the set rotation speed with higher accuracy by the minimum power of the rotating motor. can do.

Further, in the air conditioning system according to the present disclosure, the wind turbine may have fixed blades provided along the direction from the rotation axis toward the centrifugal direction. The air introduced into the humidifier from above in the vertical direction may be configured to blow out in the centrifugal direction toward the eliminator by hitting the fixing blades.

As a result, the air blown out in the centrifugal direction and the water droplets discharged in the centrifugal direction can be mixed in the eliminator, and the air flowing through the eliminator can be contained with finely divided water. Therefore, the humidifying performance of the humidifying device can be improved, and the amount of humidification for the air in the air conditioning chamber can be increased.

Further, in the air conditioning system of the present disclosure, the pumping pipes are arranged at predetermined intervals in the axial direction of the rotating shaft, and a plurality of rotating plates formed so as to project in the centrifugal direction from the outer peripheral surface of the pumping pipe are formed. It may have been done.

As a result, in the pumping pipe, the pumped water can be discharged from the pumping pipe in the centrifugal direction through the rotating plate and scattered toward the eliminator as water droplets.

Further, in the air conditioning system according to the present disclosure, the wind turbine may be arranged so as to be superimposed on the pumping pipe above the rotating plate in the vertical direction.

As a result, the wind turbine and the rotating plate can be substantially integrated, so that the humidifying device can be miniaturized. Therefore, in an air conditioning system using such a humidifying device, the air conditioning chamber can be miniaturized.

fan

3a, 3b), and the damper 5 (damper 5a). They are arranged in the order of 5b).

In the air-conditioning chamber 18, the air (indoor air) conveyed from each living room 2 through the circulation port 6 and the outside air (outdoor air) taken in from the outside by the heat exchange air fan 4 and heat-exchanged are mixed. To. The temperature and humidity of the air in the air-conditioning chamber 18 are controlled by the air-conditioning conditioner 13 and the humidifying device 16 provided in the air-conditioning chamber 18, respectively. That is, the air in the air conditioning chamber 18 is air-conditioned by the air conditioner 13 and the humidifying device 16. As a result, air to be conveyed to the living room 2 is generated.

The air conditioned in the air-conditioned room 18 is transported to each living room 2 by the transport fan 3. Here, the air-conditioning chamber 18 means a space having a certain size in which an air-conditioning conditioner 13, a humidifying device 16, a dust collecting filter 17, and the like can be arranged, and the air-conditioning of each living room 2 can be controlled. However, the air-conditioned room 18 is not limited to a living space, that is, a room in which a resident basically stays.

The air in each living room 2 is conveyed to the air conditioning room 18 via the circulation port 6. Further, the air in each living room 2 is heat-exchanged in the heat exchange air fan 4 through the living room exhaust port 7, and then discharged to the outside. In the air conditioning system 20, the inside air (indoor air) is discharged from each living room 2 by the heat exchange air fan 4, and the outside air (outdoor air) is taken into the room. As a result, the first-class ventilation system ventilation is performed. The ventilation air volume of the heat exchange air fan 4 can be set in a plurality of stages, and may be set so as to satisfy the required ventilation volume specified by law.

The heat exchange air fan 4 is configured to have an air supply fan and an exhaust fan (not shown) inside. By operating each fan in the heat exchange air fan 4, each living room 2 can be ventilated while exchanging heat between the inside air (indoor air) and the outside air (outdoor air). At this time, the heat exchange air fan 4 conveys the heat exchanged outside air to the air conditioning chamber 18.

A conveyor fan 3 is provided on the wall surface (wall surface on the bottom surface side) of the air conditioning chamber 18. The air in the air-conditioning chamber 18 is conveyed from the living room air supply port 8 to the living room 2 by the transport fan 3 via the transport duct. More specifically, the air in the air conditioning room 18 is conveyed to the living room 2a and the living room 2b located on the first floor of the general house 1 by the transport fan 3a, respectively, and the living room 2c and the living room 2c located on the second floor of the general house 1 are conveyed by the transport fan 3b. They are transported to the living room 2d respectively. The transport ducts connected to the living room air supply ports 8 of each living room 2 are independently provided.

The damper 5 adjusts the amount of air blown to each living room 2 by adjusting the opening degree of the damper 5 when the air is conveyed from the transport fan 3 to each living room 2. 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. 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 difference between the air volume (supply air volume) conveyed from the air conditioning chamber 18 to each living room 2 by the transport fan 3 and the air volume (exhaust air volume) exhausted to the outside from the living room exhaust port 7 by the heat exchange air fan 4. The air volume is conveyed as circulating air from the circulation port 6 to the air conditioning chamber 18. The circulation ducts connecting the air conditioning chamber 18 and each living room 2 may be provided independently. Further, a plurality of tributary ducts connected to each living room 2 may be integrated into one circulation duct connected to the air conditioning room 18.

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

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

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

The living room temperature sensors 11 (living room temperature sensors 11a to 11d) are sensors that acquire the living room temperature (room temperature) of the corresponding living room 2 (living room 2a to 2d) and transmit it to the system controller 14.

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

The air conditioner 13 corresponds to an air conditioner. The air conditioner 13 controls the air conditioning of the air conditioning chamber 18. Specifically, 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 based on the temperature difference between the target temperature (living room target temperature) preset by the user and the living room temperature acquired by the living room temperature sensor 11.

The humidifying device 16 is provided on the downstream side of the air conditioner 13 in the air conditioning chamber 18. The humidifying device 16 sets the humidity of the air in each room 2 to be the target humidity when the humidity of the air in each room 2 (humidity in the room) is lower than the target humidity set by the user (target humidity in the room). The air in the air conditioning chamber 18 is humidified. Although the humidity in the present embodiment is shown as a relative humidity, it may be treated as an absolute humidity in a predetermined conversion process. In this case, the humidity in the air conditioning system 20 may be treated as the absolute humidity, including the humidity in the living room 2.

The dust collection filter 17 is a dust collection filter that collects particles floating in the air introduced into the air conditioning chamber 18 through the circulation port 6. The dust collecting filter 17 makes the air supplied indoors by the transport fan 3 clean air.

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 air fan 4, the conveyor fan 3, the damper 5, the living room temperature sensor 11, the living room humidity sensor 12, the air conditioner 13 and the humidifying device 16 by wireless communication.

Further, the system controller 14 has the living room temperature and the living room humidity acquired by the living room temperature sensor 11 and the living room humidity sensor 12, and the target temperature (living room target temperature) set for each of the living room 2a to 2d. ) And the target humidity (target humidity in the living room) and the like, the air conditioner 13 as an air conditioner, the humidifying device 16, the air volume of the transport fan 3, and the opening degree of the damper 5 are controlled. 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 by 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).

Here, the system controller 14 is wirelessly connected to the heat exchange air fan 4, the transfer fan 3, the damper 5, the living room temperature sensor 11, the living room humidity sensor 12, the air conditioner 13, and the humidifying device 16. This makes it possible to eliminate the need for complicated wiring work in the air conditioning system 20. However, all or part of the above-mentioned components may be configured to be communicable by wired communication.

The input / output terminal 19 is connected to the system controller 14 so as to be able to communicate with each other by wireless communication. The input / output terminal 19 receives input of information necessary for constructing the air conditioning system 20 and stores it in the system controller 14. Further, the input / output terminal 19 acquires the state of the air conditioning system 20 from the system controller 14 and displays it. Examples of the input / output terminal 19 include a mobile information terminal such as a mobile phone, a smartphone, or a tablet.

The input / output terminal 19 does not necessarily have to be connected to the system controller 14 by wireless communication, and may be communicably connected to the system controller 14 by wire 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. FIG. 2 is a schematic cross-sectional view of the humidifying device 16 constituting the air conditioning system 20.

The humidifying device 16 is located on the downstream side of the air conditioner 13 in the air conditioning chamber 18, and is a device for humidifying the air in the air conditioning chamber 18 by crushing centrifugal water. As shown in FIG. 2, the humidifying device 16 is between a suction port 31 for sucking air in the air conditioning chamber 18, an outlet 32 for blowing out humidified air into the air conditioning chamber 18, and a suction port 31 and an outlet 32. It is provided with an air passage provided in the air passage and a liquid miniaturization chamber 33 provided in the air passage.

The suction port 31 is provided on the upper surface of the housing constituting the outer frame of the humidifying device 16. The air (air flow) blown from the air conditioner 13 flows into the humidifying device 16 through the suction port 31.

The outlet 32 is provided on the side surface of the housing.

The liquid miniaturization chamber 33 is the main part of the humidifying device 16 and is a space for refining water by a centrifugal water crushing method.

The humidifying device 16 includes a wind turbine 36, a rotary shaft 35 rotated by the wind turbine 36, a rotary motor 34 attached to the rotary shaft 35, a tubular pumping pipe 37, a water storage unit 40, a first eliminator 41, and the like. It is equipped with a second eliminator 42.

The wind turbine 36 is arranged so as to be superimposed on the vertical direction of the pumping pipe 37 (more accurately, the rotating plate 38) described later, and is arranged from the air conditioning chamber 18 (air conditioner 13) to the inside of the humidifying device 16 (hereinafter, also referred to as “inside the device”). It is a fan that is rotated by the air that flows into (referred to as). The wind turbine 36 is fixed to the rotating shaft 35, and the rotating shaft 35 rotates in accordance with the rotation of the wind turbine 36. Further, the air flowing into the apparatus is introduced 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.

The rotation shaft 35 is a shaft along the vertical direction that rotates in accordance with the rotation of the wind turbine 36. In the rotating shaft 35, the pumping pipe 37 is fixed below in the vertical direction. A rotary motor 34 is fixed above the rotary shaft 35 in the vertical direction. Further, on the rotary shaft 35, the wind turbine 36 is fixed 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 of the rotary shaft 35 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 controls the rotation speed of the rotary shaft 35 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. For example, the rotary motor 34 operates so as to increase the rotation speed of the rotary shaft 35 when the rotation speed of the pumping pipe 37 by the wind turbine 36 is insufficient. Further, the rotary motor 34 operates so as to reduce the rotation speed of the rotary shaft 35 when the rotation speed of the pumping pipe 37 by the wind turbine 36 becomes excessive. That is, the rotary motor 34 has a role of assisting the rotation of the wind turbine 36 to become an appropriate rotation speed by controlling the rotation speed of the rotation shaft 35.

The pumping pipe 37 is fixed to the rotating shaft 35 inside the liquid miniaturization chamber 33. The pumping pipe 37 rotates in accordance with the rotation of the wind turbine 36 (rotating shaft 35) to pump water from a circular pumping port provided below the pumping pipe 37 in the vertical direction. More specifically, the pumping pipe 37 has an inverted conical hollow structure, and a circular pumping port is provided below the pumping pipe 37 in the vertical direction.

A rotating shaft 35 extending in the vertical direction is fixed to the center of the inverted conical top surface of the pumping pipe 37 above the vertical direction of the pumping pipe 37. The rotating shaft 35 is connected to a wind turbine 36 provided above the liquid miniaturization chamber 33 in the vertical direction. Therefore, since the rotational movement of the wind turbine 36 is conducted to the pumping pipe 37 through the rotating shaft 35, the pumping pipe 37 rotates.

On the top surface side of the inverted conical shape of the pumping pipe 37, a plurality of rotating plates 38 formed so as to project outward from the outer surface of the pumping pipe 37 are provided. A predetermined interval is provided in the axial direction of the rotating shaft 35 between the rotating plates 38 that are vertically adjacent to each other among the plurality of rotating plates 38. Each of the plurality of rotating plates 38 is formed so as to project outward from the outer peripheral surface of the pumping pipe 37.

Since the rotating plate 38 rotates together with the pumping pipe 37, a horizontal disk shape coaxial with the rotating shaft 35 is preferable. The number of rotating plates 38 may be 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 for opening 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. .. The depth of the water storage unit 40 may be designed according to the required pumping amount. Further, the bottom surface of the water storage unit 40 is formed in a mortar shape toward the pumping port. The water supply to the water storage unit 40 is performed by the water supply unit (not shown).

The first eliminator 41 is a porous body through which air can flow. The first eliminator 41 is provided on the side of the liquid miniaturization chamber 33 (outer peripheral portion in the centrifugal direction), and is arranged so that air can flow in the centrifugal direction. The water droplets discharged from the opening 39 of the pumping pipe 37 collide with the first eliminator 41, so that the water droplets are made finer. At this time, the first eliminator 41 collects finely divided water droplets among the water contained in the air passing through the liquid finening chamber 33. 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. The second eliminator 42 is arranged so that air can flow upward in the vertical direction. The second eliminator 42 is also a porous body through which air can flow.

When the air that has passed through the first eliminator 41 collides with the second eliminator 42, water droplets among the water contained in the air that has passed through the first eliminator 41 are collected by the second eliminator 42. As a result, the finely divided water droplets can be double-collected by the two eliminators (first eliminator 41 and second eliminator 42). Therefore, 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, 4A and 4B. 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. 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 rotation shaft 35 side is viewed from the outer peripheral side of the wind turbine 36 in the cross section along the line AA of FIG. 4A.

As shown in FIG. 3, 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). The air flowing into the liquid miniaturization chamber 33 collides with the fixed blades 36a of the wind turbine 36 and flows toward the outer peripheral side of the wind turbine 36 along the rotary plate 36b. 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. As a result, the wind turbine 36 rotates.

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 located on the outer peripheral side relative to the first rotary plate portion 36b1 provided at a position relatively close to the rotary shaft 35 and the first rotary plate portion 36b1. It has a second rotating plate portion 36b2 provided in.

The first rotating plate portion 36b1 is formed to have a horizontal disk shape. The second rotating plate portion 36b2 is formed to have a gently inclined surface from the horizontal position of the first rotating plate portion 36b1 toward the outer peripheral side.

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 the air (air flow) from the air conditioner 13 collides. As shown in FIG. 4A, the plurality of fixed blades 36a are provided radially at equal intervals along the direction from the rotating shaft 35 toward the outer periphery of the wind turbine 36 on the upper surface side of the rotating plate 36b. In this embodiment, 10 fixed blades 36a are formed.

As shown in FIG. 4B, in each of the plurality of fixed blades 36a, the upstream end P1 is located on the upstream side in the direction of rotation (rotational direction) with respect to the rotation axis 35. Further, in each of the plurality of fixed blades 36a, the downstream end P2 is located on the downstream side opposite to the rotation direction of the rotation shaft 35. Therefore, each of the plurality of fixed blades 36a is provided so as to be inclined with respect to the rotation direction of the rotation shaft 35.

In the wind turbine 36, the fixed blades 36a are provided so as to be inclined. Therefore, when the air from the air conditioner 13 flows toward the wind turbine 36 from above (upstream side) in the vertical direction and collides with the fixed blades 36a, the air from the air conditioner 13 generates a force in the rotational direction. As a result, the rotary plate 36b to which the fixing blades 36a are attached rotates. 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.

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. On the rotating shaft 35, a pumping pipe 37 is connected below the wind turbine 36 in the vertical direction. Further, on the rotary shaft 35, a rotary motor 34 is connected above the wind turbine 36 in the vertical direction.

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) 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 are configured to rotate integrally in accordance with the rotation of the rotary shaft 35.

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 apparatus are indicated by arrows.

First, when the humidifying device 16 starts operating, the air of the air conditioner 13 flows into the humidifying device 16 through the suction port 31. The air flowing in through the suction port 31 collides with the fixed blades 36a of the wind turbine 36, and the wind turbine 36 rotates. At this time, the rotation restriction of the rotating shaft 35 by the rotating motor 34 is released.

When the wind turbine 36 rotates the rotation shaft 35 at the first rotation speed R1 which is the set rotation speed, 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 that the rotation of the rotary shaft 35 becomes 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 of the rotary shaft 35 when the rotation speed of the pumping pipe 37 by the wind turbine 36 is insufficient based on the information regarding the air volume (blower volume) of the air conditioner 13. When the rotation speed of the pumping pipe 37 by the wind turbine 36 becomes excessive, the rotation speed of the rotating shaft 35 is reduced.

As shown by the flow of water indicated by the broken arrow in FIG. 2, the water stored in the water storage unit 40 is pumped up by the pumping pipe 37 due to 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.

The pumping pipe 37 has an inverted conical hollow structure. Therefore, the water pumped up by the rotation of the wind turbine 36 is pumped to the upper part of the pumping pipe 37 along the inner wall of the pumping pipe 37. The water pumped to the upper part of the pumping pipe 37 is discharged from the opening 39 of the pumping pipe 37 through the rotary plate 38 in the outer peripheral direction (centrifugal direction) of the wind turbine 36, 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. Move to the outer peripheral portion of 41. The process of air flowing in the air passage from the first eliminator 41 to the second eliminator 42 creates an airflow vortex, and water and air are mixed in the apparatus. The water-containing air 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 air 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.

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

(1) The air conditioner system 20 is installed in an air conditioner room 18 configured to allow air to be introduced from indoors and outdoors, an air conditioner 13 installed in the air conditioner room 18 to control the temperature of the air in the air conditioner room 18, and an air conditioner room 18. A humidifying device 16 for humidifying the air temperature controlled by the air conditioner 13 and a transport fan 3 for transporting the air in the air conditioner room 18 to an indoor space different from the air conditioner room 18 are provided. The humidifying device 16 is arranged in a flow path through which the air temperature controlled by the air conditioner 13 flows into the device, and is fixed to the windmill 36 that is rotated by the air flowing into the device and the windmill 36, and is fixed to the windmill 36 with the rotation of the windmill 36. A cylindrical pumping water that is fixed to the rotating shaft 35 and is fixed to the rotating shaft 35 and is rotated together with the rotating shaft 35 to pump water from a pumping port provided below in the vertical direction and discharge the pumped water in the centrifugal direction. When the pipe 37 and the water discharged from the pumping pipe 37 collide with each other, the collided water is made finer, and the first eliminator 41 that collects a part of the finely divided water and the lower part of the pumping pipe 37 in the vertical direction. It is configured to have a water storage unit 40 for storing water pumped from a pumping port.

According to such a configuration, the wind turbine 36 receives the wind pressure corresponding to the amount of air blown from the air conditioner 13 to rotate the rotating shaft 35, and the rotation of the rotating shaft 35 causes the pumping pipe 37 to rotate. Therefore, the energy consumption by the humidifying device 16 can be suppressed as compared with the case where the rotating shaft is rotated by the power of the rotating motor as in the conventional humidifying device. Therefore, the energy efficiency of the humidifying device 16 can be improved. That is, the air conditioning system 20 using the humidifying device 16 that can contribute to energy saving can be obtained.

(2) The air conditioning system 20 further includes a rotary motor 34 to which a rotary shaft 35 is rotatably attached. The rotary motor 34 adjusts the rotation speed of the rotary shaft 35 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 from the air conditioner 13 (wind pressure) varies, the rotation speed of the rotating shaft 35 is maintained at the set rotation speed. Therefore, the pumping pipe 37 can be rotated at a set rotation speed. Therefore, the humidifying capacity of the humidifying device 16 can be stabilized.

(3) In the air conditioning system 20, the rotary motor 34 operates so as to increase the rotation speed of the rotary shaft 35 when the rotation speed of the pumping pipe 37 is insufficient, based on the information regarding the air flow amount of the air conditioner 13. However, when the rotation speed of the pumping pipe 37 becomes excessive, it operates so as to reduce the rotation speed of the rotation shaft 35.

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.

(4) In the air conditioning system 20, the wind turbine 36 has a fixed blade 36a provided along the direction toward the centrifugal direction from the rotating shaft 35. The fixed blade 36a is configured so that air introduced into the apparatus from above in the vertical direction hits the fixed blade 36a and blows out toward the first eliminator 41 in the centrifugal direction.

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 can be contained with finely divided water. can. 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.

Thereby, 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 scattered toward the first eliminator 41 as water droplets.

(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 rotating motor 34 for stabilizing the rotation, so that the energy saving of the humidifying device 16 can be realized.

(8) In the air conditioning system 20, a wind turbine 36 is provided in the air passage for introducing the air temperature-controlled by the air conditioner 13 into the humidifying device 16, and the air passing through the wind turbine 36 is finely divided by centrifugal crushing. It was configured to contain the conditioned water and release it.

As a result, since the air is introduced into the humidifying device 16 by the wind turbine 36, the humidifying amount for the air in the air conditioning chamber 18 can be adjusted independently of the amount of air conveyed from the air conditioning chamber 18 by the transport fan 3. ..

Although the present disclosure has been described above based on the embodiments, the present disclosure is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present disclosure. It is easy to guess. For example, the numerical values given in the above embodiment are examples, and it is naturally possible to adopt 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 becomes the target rotation speed based on the information regarding the air volume (blower volume) of the air conditioner 13. I can't. For example, the rotary motor 34 may detect the rotation speed of the wind turbine 36 and control the rotation of the wind turbine 36 to be the target rotation speed based on the information regarding the detected rotation speed. Even in this way, the same effect can be enjoyed.

Further, in the air conditioning system 20 according to the present embodiment, an air conditioning room temperature sensor for detecting the temperature of the air in the air conditioning room 18 may be provided in the air conditioning room 18. As a result, the humidity control in the air conditioning chamber 18 can be controlled with higher accuracy.

In addition, the living room in this embodiment does not necessarily have to have people, and can be regarded as one space. In other words, if the corridor or kitchen is also divided to some extent, it can be regarded as one space, and corresponds to one living room.

Further, the air conditioning system 20 according to the present embodiment can be applied to a detached house or a complex house such as a condominium. However, when the air conditioning system 20 is applied to an apartment house, one system corresponds to each household, not each household as one living room.

The air conditioning system according to the present disclosure is useful as a whole building air conditioning system using a humidifying device that can contribute to energy saving.
