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 humidified by the humidifier also installed in the air conditioning room. I am in control. In particular, the humidifier used in winter can use the air heated by the heat source of the air conditioner, so that the amount of humidification for the air in the air conditioner can be increased. However, when the temperature of the air in a plurality of spaces (living rooms) reaches the target temperature, the heat source of the air conditioner is stopped or the amount of heat is reduced, so that the temperature of the air in the air conditioning room is lowered. In the humidifier, the amount of humidification for the air in the air conditioning room is reduced. For this reason, in the conventional whole building air conditioning system, it may take a long time for the humidity of the air in a plurality of spaces (living rooms) to reach the target humidity. That is, in the conventional whole building air conditioning system, there is a problem that the humidifying performance of the humidifier changes depending on the operation of the heat source of the air conditioner, and the humidification control by the humidifier is not stable.

The present invention has been made to solve the above problems, and provides an air conditioning system capable of performing humidification control by a humidifying device linked with temperature control by an air conditioner.

In order to achieve this object, the air conditioning system according to the present invention includes 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.

Then, in order to adjust the temperature of the indoor air to the target temperature, the control unit performs temperature control using the air in the air conditioning room that has been raised to the first temperature, which is a temperature higher than the target temperature by the air conditioner. .. At that time, if the humidity of the indoor air is equal to or higher than the target humidity, when the temperature of the indoor air rises and reaches the target temperature, the air conditioner makes the air in the air conditioning room higher than the first temperature. The first control is performed to adjust the temperature to the second temperature, which is a low temperature, and when the humidity of the indoor air is less than the target humidity, the temperature of the indoor air rises and reaches the target temperature. It is characterized in that the air in the air-conditioning chamber is maintained at the first temperature and controlled so as to perform the second control for controlling the temperature.

According to the present invention, it is possible to provide an air conditioning system capable of performing humidification control by a humidifying device linked with temperature control by an air conditioner.

Then, in order to adjust the temperature of the indoor air to the target temperature, the control unit performs temperature control using the air in the air conditioning room that has been raised to the first temperature, which is a temperature higher than the target temperature by the air conditioner. .. At that time, if the humidity of the indoor air is equal to or higher than the target humidity, when the temperature of the indoor air rises and reaches the target temperature, the air conditioner makes the air in the air conditioning room higher than the first temperature. The first control is performed to adjust the temperature to the second temperature, which is a low temperature, and when the humidity of the indoor air is less than the target humidity, the temperature of the indoor air rises and reaches the target temperature. It is characterized in that the air in the air-conditioning chamber is maintained at the first temperature and controlled so as to perform the second control for controlling the temperature.

According to such a configuration, the temperature control (first control or second control) by the air conditioner linked with the humidification control by the humidifier is performed, so that the humidifying capacity (humidification) of the humidifier caused by the temperature control of the air conditioner is performed. It is possible to suppress a decrease in the amount) and stabilize the humidification performance as an air conditioning system. That is, since the air heated to the first temperature is continuously introduced into the humidifying device by the air conditioner, the amount of humidification for the air in the air conditioning chamber can be increased as compared with the conventional air conditioning system.

It is preferable to reduce the first air volume to the second air volume, which is smaller than the first air volume. As a result, in the second control, the amount of air transported indoors by the transfer fan is reduced, so that the temperature of the indoor air rises (indoors) due to maintaining the temperature of the air in the air conditioning room at the first temperature. It is possible to control the humidification by the humidifying device toward the target humidity while suppressing the phenomenon that the temperature of the air becomes higher than the target temperature).

Further, the air conditioning system of the present invention further includes a temperature / humidity sensor that acquires the temperature / humidity of the indoor air and transmits it to the control unit. Then, the control unit controls the temperature of the indoor air to the target temperature for the air conditioner based on the information about the temperature and humidity from the temperature / humidity sensor, and also controls the temperature of the indoor air for the humidifier indoors. Humidity control may be performed to humidify the humidity of the air to the target humidity. As a result, it is possible to control the temperature control by the air conditioner and the humidity control by the humidifying device in accordance with the change in the temperature and humidity of the indoor air, so that the comfort in the indoor space can be improved.

Further, in the air conditioning system of the present invention, the humidifying device includes a centrifugal fan that introduces air temperature-controlled by the air conditioner into the device, and water that is refined by centrifugal crushing with respect to the air introduced by the centrifugal fan. It is preferable to have a humidifying portion for discharging.

As described above, each living room exhaust port 7 (living room exhaust port 7a to 7d) is an opening for transporting indoor air from each 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 air in the air conditioning room 18 from the air conditioning room 18 to each 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 each 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 each of the 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 and controls the air conditioning of 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. In the present embodiment, the set temperature is set to a first temperature which is at least higher than the target temperature in order to adjust the temperature of the air in each living room 2 to the target temperature more quickly.

The humidifying device 16 is located on the downstream side of the air conditioner 13 in the air conditioner room 18, and the humidity of the air in each room 2 (room humidity) is lower than the target humidity set by the user (room target humidity). In this case, the air in the air conditioner chamber 18 is humidified so that the humidity becomes the 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).

Here, the system controller 14, 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 are connected by wireless communication.

It is acquired from the controller 14 and displayed. Examples of the input / output terminal 19 include mobile information terminals such as mobile phones, smartphones, and tablets.

The input / output terminal 19 does not necessarily have to be connected to the system controller 14 by wireless communication, and may be 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.

The suction port 31 is provided on the upper surface of the housing constituting the outer frame of the humidifying device 16, and the air outlet 32 is provided on the side surface of the housing. The liquid miniaturization chamber 33 is a main part of the humidifying device 16, and is a place where water is miniaturized by a centrifugal water crushing method.

Specifically, the humidifying device 16 includes a rotary motor 34, a rotary shaft 35 rotated by the rotary motor 34, a centrifugal fan 36, a tubular pumping pipe 37, a water storage unit 40, a first eliminator 41, and a first eliminator. It is equipped with two eliminators 42.

The pumping pipe 37 is fixed to the rotating shaft 35 inside the liquid miniaturization chamber 33, and while rotating in accordance with the rotation of the rotating shaft 35, water is pumped from a circular pumping port provided downward in the vertical direction. More specifically, the pumping pipe 37 has an inverted conical hollow structure, has a circular pumping port downward in the vertical direction, and is above the pumping pipe 37 at the center of the inverted conical top surface. , The rotating shaft 35 arranged in the vertical direction is fixed. By connecting the rotary shaft 35 to the rotary motor 34 located vertically above the liquid miniaturization chamber 33, the rotary motion of the rotary motor 34 is conducted to the pumping pipe 37 through the rotary shaft 35, and the pumping pipe 37 rotates. do.

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 centrifugal fan 36 is arranged above the pumping pipe 37 in the vertical direction and is a fan for taking in air from the air conditioning chamber 18 into the apparatus. The centrifugal fan 36 is fixed to the rotation shaft 35 like the pumping pipe 37, and by rotating in accordance with the rotation of the rotation shaft 35, air is introduced into the liquid miniaturization chamber 33.

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. 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, 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. 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 operating principle of humidification (miniaturization of water) in the humidifying device 16 will be described.

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 operation of the humidifying device 16 is started, the rotary motor 34 rotates the rotary shaft 35 at the first rotation speed R1, and the centrifugal fan 36 starts sucking air from the air conditioning chamber 18 from the suction port 31. Then, the pumping pipe 37 rotates in accordance with the rotation of the rotating shaft 35 at the first rotation speed R1. 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 due to the centrifugal force generated by the rotation. Here, the first rotation speed R1 of the rotary motor 11 (pumping pipe 37) is set between 2000 rpm and 5000 rpm, for example, depending on the amount of air blown and the amount of humidification to the air. Since the pumping pipe 37 has an inverted conical hollow structure, the water pumped by the 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 moves to the outer peripheral portion of the first eliminator 41 while containing the water crushed (miniaturized) by the first eliminator 41 like the air flow indicated by the solid arrow. .. 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.

The living room target temperature is set as a predetermined temperature range defined by the lower limit being the minimum temperature and the upper limit being the maximum temperature. The living room target humidity is set as a predetermined humidity range defined by the lower limit being the minimum humidity and the upper limit being the maximum humidity. Here, a temperature equal to or higher than the target temperature of the living room means a temperature equal to or higher than the maximum temperature of the upper limit, and a temperature smaller than the target temperature of the living room means a temperature smaller than the minimum temperature of the lower limit. The same applies to the target humidity in the living room. In the present embodiment, the living room target temperature and the living room target humidity can be set by the user, but they may be set as fixed values in the air conditioning system 20 in advance.

The difference (humidity difference) between the room humidity acquired by the humidity acquisition unit 51 or preset, and the room humidity acquired by the room humidity sensor 12 is calculated for each room 2.

The control condition determination unit 58 determines the control conditions of the air conditioner 13, the humidifier 16, the transfer fan 3, and the damper 5 based on the temperature difference and the humidity difference calculated for each living room 2 by the temperature / humidity difference calculation unit 57. do.

That is, the air-conditioning control unit 52 is the temperature output by the information on the room target temperature / humidity from the room target temperature / humidity acquisition unit 51 and the information on the room room / humidity from each sensor (room temperature sensor 11, room humidity sensor 12). The outputs of the air conditioner 13, the humidifying device 16, the transfer fan 3, and the damper 5 are determined based on the information regarding the difference and the humidity difference.

The air conditioner control unit 53 controls the operation mode, the blowout temperature, and the air flow amount of the air conditioner 13 in the air conditioner room 18 based on the control method determined by the air conditioner control unit 52.

The rotary motor control unit 54 controls the rotation speed of the rotary motor 34 provided in the humidifying device 16 to provide a humidifying device in the air conditioning chamber 18 based on the control conditions determined by the air conditioning control unit 52. The humidification amount of 16 is controlled.

The air volume control unit 55 controls the air volume of the transfer fan 3 provided corresponding to the living room 2 and the opening degree of the damper 5 based on the control conditions determined by the air conditioning control unit 52.

The storage unit 56 is a so-called memory that stores a predetermined temperature range, that is, the maximum temperature and the minimum temperature, and a humidity range, that is, the maximum humidity and the minimum humidity, which are acquired by the living room target temperature / humidity acquisition unit 51 or set in advance. be. In addition, the storage unit 56 is also used when it is necessary to store information such as numerical values for control by the system controller 14.

Next, the air conditioning process executed by the system controller 14 will be described with reference to FIGS. 4 to 6. FIG. 4 is a flowchart showing the air conditioning processing procedure. FIG. 5 is a flowchart showing a processing procedure in the temperature control priority control mode in the air conditioning processing procedure. FIG. 6 is a flowchart showing a processing procedure in the humidity control priority control mode in the air conditioning processing procedure. Here, since the air conditioning process in winter in Japan is assumed, in the air conditioning system 20, the air conditioner 13 is in a situation where the humidifying device 16 humidifies the air while raising the temperature of the air in the living room 2.

In the air-conditioning system 20, the heat exchange air fan 4 is constantly ventilated, as in the general central air-conditioning system, and the transport fan 3 is set to the third air volume even when the air-conditioning process is not performed. The damper 5 is set at the third opening and blows air (step S11). Here, the third air volume is an air volume that satisfies the required ventilation volume stipulated by law in the house, and the air supplied into the air conditioning chamber 18 by the heat exchange air fan 4 is transported to the living room 2 by the transport fan 3. do. Further, the third opening degree is set to, for example, fully open. When only the heat exchange air fan 4 is being operated, the air conditioner 13 and the humidifying device 16 are stopped.

When the user executes the air conditioning process, first, the system controller 14 acquires the living room target temperature / humidity (living room target temperature and living room target humidity) set in the input / output terminal 19 and stores them in the storage unit 56 (step S12). ). Here, the target temperature / humidity of the living room is a temperature / humidity that the user feels comfortable with, and is a temperature / humidity common to all living rooms.

When the target temperature / humidity of the living room is acquired, the air conditioning control unit 52 acquires information on the room temperature / humidity from the living room temperature sensor 11 and the living room humidity sensor 12 installed in each living room 2 (step S13). Subsequently, the air conditioning control unit 52 uses the temperature / humidity difference calculation unit 57 to calculate the temperature difference and the humidity difference with respect to the target from the acquired information on the target temperature / humidity in the room and the information on the room temperature / humidity (step S14).

Then, the control condition determination unit 58 specifies the target temperature and humidity of the air conditioning room (target temperature of the air conditioning room and the target humidity of the air conditioning room) with respect to the air of the air conditioning room 18 based on the calculated temperature difference and humidity difference (step S15). Here, the air-conditioning room target temperature is set to the first temperature, which is a temperature higher than the living room target temperature, and the air-conditioning room target humidity is set to the first humidity, which is a humidity higher than the living room target humidity.

Then, the air conditioning control unit 52 determines the control conditions of the air conditioner 13, the humidifying device 16, the transfer fan 3, and the damper 5 based on the specified target temperature and humidity of the air conditioning room, and executes each of them (step S16).

Specifically, the air conditioner control unit 53 starts the operation of the air conditioner 13 based on the control conditions from the air conditioner control unit 52, and the temperature of the air in the air conditioner room 18 is the target temperature of the air conditioner room (first). The temperature is controlled so that it becomes (temperature). The rotary motor control unit 54 starts the rotary operation of the rotary motor 34 based on the control conditions from the air conditioning control unit 52 so that the humidity of the air in the air conditioning chamber 18 becomes the target humidity (first humidity) in the air conditioning chamber 18. , Rotate at the first rotation speed R1 (2000 rpm to 5000 rpm). The air volume control unit 55 changes the air volume of the conveyor fan 3 and the opening degree of the damper 5 to the first air volume and the first opening degree, respectively, based on the control conditions from the air conditioning control unit 52. The first opening degree is set according to the temperature difference between the temperature of the air in the living room 2 and the target temperature of the living room. Is set to.

Then, when the predetermined time T starting from the step in which the control conditions are changed (here, step S16) elapses during the air conditioning operation (Yes in step S17), the air conditioning control unit 52 moves to each living room 2. Information on the room temperature and humidity is newly acquired from the room temperature sensor 11 and the room humidity sensor 12 installed (step S18). On the other hand, when the predetermined time T has not elapsed (No in step S17), the air conditioning control unit 52 continues the air conditioning operation under the same control conditions (returns to step S17). Here, the predetermined time T is the acquisition cycle time of the room room humidity in the room temperature sensor 11 and the room humidity sensor 12, and is set to, for example, 5 minutes.

Next, the air-conditioning control unit 52 determines whether or not the living room humidity is equal to or higher than the living room target humidity among the acquired living room room humidity (step S19). As a result, when the humidity in the living room is equal to or higher than the target humidity in the living room, the air conditioning control unit 52 shifts the air conditioning operation to the temperature control priority control mode M1 (step S30). On the other hand, when the living room temperature does not reach the living room target temperature, the air conditioning control unit 52 shifts the air conditioning operation to the humidity control priority control mode M2 (step S40).

Here, the temperature control priority control mode M1 is a mode in which the temperature control by the air conditioner 13 is executed without being affected by the humidity control by the humidifying device 16. The humidity control priority control mode M2 is a mode in which the temperature control by the air conditioner 13 is executed under the influence of the humidity control by the humidifying device 16.

Subsequently, in the temperature control priority control mode M1, the air conditioning control unit 52 determines whether or not the living room temperature is equal to or higher than the living room target temperature among the acquired living room room humidity (step S31). As a result, when the living room temperature is equal to or higher than the living room target temperature (Yes in step S31), the air conditioning control unit 52 changes the control conditions of the air conditioner 13 to execute. Specifically, the air conditioner control unit 53 sets the temperature of the air in the air conditioner chamber 18 to be the new target temperature (second temperature) of the air conditioner chamber 18 based on the new control conditions from the air conditioner control unit 52. Perform temperature control. Then, the next step S34 is executed.

Here, the second temperature is a temperature lower than the first temperature. The second temperature is preferably the temperature required to maintain the living room temperature within the living room target range. The temperature change from the first temperature to the second temperature is realized, for example, by stopping the temperature control operation of the air conditioner 13.

On the other hand, when the living room temperature is not equal to or higher than the living room target temperature (No in step S31), the air conditioning control unit 52 does not change the control conditions of the air conditioner 13 and the air conditioner control unit 53 is the air conditioner 13. The operation of adjusting the temperature to the first temperature is maintained and executed. Then, the next step S34 is executed.

Subsequently, in step S34, the air conditioning control unit 52 determines whether or not the living room humidity exceeds the living room target humidity among the acquired living room room humidity. As a result, when the humidity in the living room exceeds the target humidity in the living room (Yes in step S34), the air conditioning control unit 52 changes the control conditions of the humidifying device 16 and executes the operation. Specifically, the rotary motor control unit 54 changes the rotational operation of the rotary motor 34 based on the new control conditions from the air conditioning control unit 52, and the humidity of the air in the air conditioning chamber 18 is the new target humidity of the air conditioning chamber. It is rotated at the second rotation speed R2 (0 rpm to 2000 rpm) so as to be (second humidity). The air volume control unit 55 maintains the air volume of the conveyor fan 3 and the opening degree of the damper 5 in the state of the first air volume and the first opening degree based on the new control condition from the air conditioning control unit 52. Step S35). Then, the process returns to step S17. In step S17, the predetermined time T is timed starting from the step in which the control conditions are changed (here, step S35).

On the other hand, when the humidity in the living room does not exceed the target humidity in the living room (No in step S34), the air conditioning control unit 52 does not change the control conditions of the humidifying device 16, and the rotary motor control unit 54 uses the rotary motor. The rotation operation of 34 (first rotation number R1) is maintained. Further, the air volume control unit 55 maintains the air volume of the conveyor fan 3 and the opening degree of the damper 5 in the same state as the first air volume and the first opening degree (step S36). Then, the process returns to step S17. In step S17, the predetermined time T is timed starting from the step in which the control conditions are changed (here, step S36).

In the temperature control priority control mode M1, the air conditioning operation is executed as described above.

Next, in the humidity control priority control mode M2, based on the determination in step S19, the control condition of the humidifying device 16 is not changed, and the operation of controlling the humidity to the first humidity is maintained and executed. Specifically, the rotary motor control unit 54 has a first rotation speed R1 (2000 rpm to 5000 rpm) so that the humidity of the air in the air conditioning chamber 18 becomes the first humidity without changing the rotational operation of the rotary motor 34. Rotate with (step S41).

Next, the air-conditioning control unit 52 determines whether or not the living room temperature is equal to or higher than the living room target temperature among the living room room humidity acquired in step S18 (step S42). As a result, when the living room temperature is equal to or higher than the living room target temperature (Yes in step S42), the air conditioning control unit 52 does not change the control conditions of the air conditioner 13 and the air conditioner control unit 53 is the air conditioner. The operation of adjusting the temperature to the first temperature is maintained and executed with respect to 13. Then, the air volume control unit 55 changes the air volume of the conveyor fan 3 and the opening degree of the damper 5 to the second air volume and the second opening degree (step S43). The processing in steps S42 and S44 corresponds to the "second control" of the claim.

Here, the second air volume is smaller than the first air volume. As a result, the air temperature-controlled to the first temperature in the air-conditioned room 18 is less likely to be discharged to the outside of the air-conditioned room 18, so that the amount of humidification for the air in the air-conditioned room 18 can be increased. Further, the second opening degree is set according to the temperature difference between the air temperature of the living room 2 and the living room target temperature, as in the first opening degree, and is set so as to widen if the temperature difference is large, for example. If the temperature difference is small, it is set to be narrow. Then, the process returns to step S17. In step S17, the predetermined time T is timed starting from the step in which the control conditions are changed (here, step S43).

On the other hand, when the living room temperature is not equal to or higher than the living room target temperature (No in step S42), the air conditioning control unit 52 does not change the control conditions of the air conditioner 13 and the air conditioner control unit 53 is the air conditioner 13. The operation of adjusting the temperature to the first temperature is maintained and executed. Then, the air volume control unit 55 maintains the air volume of the conveyor fan 3 and the opening degree of the damper 5 in the state of the first air volume and the first opening degree. Then, the process returns to step S17. In step S17, the predetermined time T is timed starting from the step in which the control conditions are changed (here, step S44).

In the humidity control priority control mode M2, the air conditioning operation is executed as described above.

In the air conditioning system 20 according to the present embodiment, the room room temperature / humidity in the living room 2 is controlled to reach the living room target temperature / humidity by the above series of processes.

When the air-conditioning system 20 is temperature-controlled like a conventional whole-building air-conditioning system, when the room temperature in the room 2 reaches the room target (room target temperature) before the room humidity, in order to avoid unnecessary energy consumption. , The temperature control is performed such that the air conditioner 13 is stopped or the heating amount is lowered. As a result, the temperature of the air in the air conditioning chamber 18 drops from the first temperature. In the present embodiment, it is assumed that the air conditioner 13 adjusts the temperature to the second temperature, which is lower than the first temperature, in the situation where the temperature drops. As a result, in the humidifying device, the amount of humidification for the air in the air-conditioned room is reduced, and the time until the humidity of the air in the living room 2 reaches the target humidity in the living room becomes long.

On the other hand, in the air conditioning system 20 according to the present embodiment, even if the room temperature in the room 2 reaches the room target (room target temperature) before the room humidity, the air conditioner 13 is stopped or the heating amount is reduced. The temperature control at the first temperature is maintained without controlling the temperature control. As a result, it is possible to suppress a decrease in the amount of humidification for the air in the air conditioning chamber 18, and it is possible to efficiently bring the humidity of the air in the air conditioning chamber 18 to the target humidity in the living room.

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

(1) In the air conditioning system 20, in order to adjust the temperature of the air in the living room 2 to the target temperature in the living room, the air conditioning conditioner 13 raises the temperature to the first temperature (target temperature in the air conditioning room) which is higher than the target temperature in the living room. The temperature control is performed using the air in the air-conditioned room 18. At that time, if the humidity of the air in the living room 2 is equal to or higher than the target humidity in the living room, the air temperature in the living room 2 rises and reaches the target temperature in the living room. The first control is performed to adjust the temperature to the second temperature, which is lower than the first temperature, and when the humidity of the air in the living room 2 is less than the target humidity of the living room (when the humidity is not higher than the target humidity of the living room). When the temperature of the air in the living room 2 rises and reaches the target temperature in the living room, the air conditioner 13 is controlled to maintain the air in the air conditioning room 18 at the first temperature and perform the second control to control the temperature.

As a result, the temperature control (first control or second control) by the air conditioner 13 linked with the humidification control by the humidifier 16 is performed, so that the humidifying capacity of the humidifier 16 due to the temperature control of the air conditioner 13 (1st control or the second control) is performed. It is possible to suppress a decrease in the amount of humidification) and stabilize the humidification performance of the air conditioning system 20. That is, since the air heated to the first temperature is continuously introduced into the humidifying device 16, the amount of humidification for the air in the air conditioning chamber 18 is increased as compared with the conventional air conditioning system. Therefore, the humidity of the air in the air conditioner chamber 18 can be efficiently reached to the target humidity of the air conditioner chamber. As a result, the air conditioning system 20 capable of efficiently controlling the temperature and humidity of the living room 2 can be obtained.

(2) In the air conditioning system 20, when the second control is performed, the amount of air to be conveyed to the indoor space by the transfer fan 3 is set when the temperature of the air in the living room 2 reaches the target temperature in the living room. It was configured to reduce the air volume from one air volume to the second air volume, which is less than the first air volume. As a result, in the second control, the amount of air conveyed to the living room 2 by the transfer fan 3 is reduced, so that the temperature of the air in the living room 2 is associated with maintaining the temperature of the air in the air conditioning chamber 18 at the first temperature. (Phenomenon in which the temperature of the air in the living room 2 becomes higher than the target temperature in the living room) can be suppressed, and the humidification control by the humidifying device 16 can be performed toward the target humidity in the living room.

(3) The air-conditioning system 20 includes a living room temperature sensor 11 and a living room humidity sensor 12 that acquire the temperature and humidity of the air in the living room 2 and transmit the temperature and humidity to the system controller 14, and the system controller 14 includes the living room temperature sensor 11 and the living room humidity sensor. Based on the information on the room temperature and humidity from 12, the air conditioner 13 is controlled to control the temperature of the air in the room 2 to the target temperature in the room, and the humidifying device 16 is controlled to control the temperature of the air in the room 2. It was configured to perform humidity control to humidify the humidity to the target humidity in the living room. As a result, it is possible to control the temperature control by the air conditioner 13 and the humidity control by the humidifying device 16 in accordance with the change in the temperature and humidity of the air in the living room 2, so that the comfort in the indoor space can be improved.

(4) In the air conditioning system 20, the humidifying device 16 is refined by centrifugal crushing with respect to the centrifugal fan 36 that introduces the air temperature-controlled by the air conditioner 13 into the device and the air introduced by the centrifugal fan 36. It is configured to have a humidifying section (liquid micronization chamber 33) that contains and discharges water. As a result, since the air is introduced into the humidifying device 16 by the centrifugal fan 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. can.

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. 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, in order to adjust the temperature of the air in the living room 2 to the target temperature in the living room, the air conditioner 13 makes the air in the air conditioning room 18 higher than the target temperature in the living room. Temperature control was performed using air that had been heated to (the target temperature of the air conditioning room), but this is not limited to this. For example, the system controller 14 may control the air-conditioning room target temperature / humidity (particularly the air-conditioning room target temperature) in accordance with the living room target temperature / humidity (particularly the living room target temperature). Even in this way, the same effect can be enjoyed.

Further, in the air conditioning system 20 according to the present embodiment, in the air conditioning chamber 18, an air conditioning chamber temperature sensor that detects the temperature of the air in the air conditioning chamber 18 and an air conditioning chamber humidity sensor that detects the humidity of the air in the air conditioning chamber 18 are provided. May be provided. Thereby, the temperature control and the humidity control can be controlled more accurately and surely in order to make the temperature and humidity in the air conditioning chamber 18 the set air conditioning room temperature and humidity.

Further, in the air conditioner system 20 according to the present embodiment, even if the room temperature in the room 2 reaches the room target (room target temperature) before the room humidity, the air conditioner 13 is stopped or the heating amount is reduced. I tried to maintain the temperature control at the first temperature without controlling the temperature control, but if the room temperature exceeds the maximum temperature of the upper limit of the room target temperature, the air conditioner 13 is stopped or heated. It is preferable to perform temperature control (control to control the temperature of the air in the air conditioner room 18 to a second temperature lower than the first temperature) by lowering the amount. As a result, it is possible to suppress a decrease in comfort in the indoor space.

Further, in the present embodiment, although it is shown as a living room, the living room does not necessarily have to have a person 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 complex house such as a detached house or 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 invention is useful as it can efficiently control air conditioning to supply air to a plurality of spaces (living rooms) and the like.
