(Embodiment 1)

First, an air conditioning system 20 according to a first embodiment of the present invention will be described with reference to FIG. 1 . FIG. 1 is a schematic connection diagram of an air conditioning system 20 according to the first embodiment.

The air conditioning system 20 includes an outside air introduction fan 4, a plurality of exhaust fans 5 (exhaust fans 5a, 5b, 5c, 5d), a plurality of delivery fans 3 (transport fans 3a, 3b, 3c, 3d), and a plurality of circulation fans. 6 (6a, 6b, 6c, 6d), room temperature sensor 11 (room temperature sensor 11a, 11b, 11c, 11d), room humidity sensor 12 (room humidity sensor 12a, 12b, 12c, 12d), air-conditioning room temperature sensor 14 , air-conditioning room humidity sensor 15, air conditioner 9, humidifier 16, dehumidifier 17, input and output terminal 19, and system controller 10 (corresponding to the air-conditioning system controller).

The air conditioning system 20 is installed in a general house 1 which is an example of a building. The general house 1 has at least one air-conditioning room 18 independent of the living room 2 in addition to a plurality (four in this embodiment) of living rooms 2 (rooms 2a, 2b, 2c, 2d). Here, the general house 1 (house) refers to a house provided as a place for residents to live privately, and the living room 2 includes a living room, a dining room, a bedroom, a private room, a children's room, and the like as a general structure. In addition, the living room provided by the air conditioning system 20 may include a toilet, a bathroom, a washroom, a dressing room, and the like.

In the air-conditioning room 18, the air sent from each living room 2 is mixed with each other. In addition, the outside air is taken into the air-conditioning room 18 by the outside air introduction fan 4 and mixed with the air sent from each living room 2 by the circulation fan 6 . The air in the air-conditioning room 18 is controlled in temperature and humidity by the air conditioner 9 , humidifier 16 , and dehumidifier 17 installed in the air-conditioning room 18 , that is, the air is conditioned, and air to be sent to the living room 2 is generated. The air conditioned by the air-conditioning room 18 is sent to each living room 2 by the delivery fan 3 . Here, the air-conditioning room 18 refers to a space including a certain size that can be equipped with an air conditioner 9 or other humidifiers 16, dehumidifiers 17, etc., and can control the air conditioning of each room, but it is not a living space, and basically does not refer to a place where occupants stay. Room.

In addition to being sent to the air-conditioning room 18 by the circulation fan 6, the air in each living room 2 is exhausted from the inside of the living room 2 to the outside of the general house 1 by the exhaust fan 5 as outside air. The air conditioning system 20 controls the exhaust air volume of the exhaust fan 5 to discharge the outside air from the room, and simultaneously controls the air supply air volume of the outside air introduction fan 4 to take in the outside air in conjunction with the exhaust air volume of the exhaust fan 5. Indoor, thus, the ventilation of the first ventilation method is carried out.

The outside air introduction fan 4 is a fan for taking in outside air into the room of the general house 1, and fulfills an air supply function such as an air supply fan or a heat exchange ventilation fan. As described above, the outside air taken in by the outside air introduction fan 4 is introduced into the air-conditioning room 18 . The supply air volume of the external air introduction fan 4 is configured to be settable in multiple stages, and the supply air volume is set according to the exhaust air volume of the exhaust fan 5 as described later.

The exhaust fan 5 is a fan that discharges a part of the air in the corresponding living room 2 as external air through, for example, an exhaust duct, and meets the exhaust functions of a ceiling exhaust fan, a wall-mounted exhaust fan, a range hood, a heat exchange ventilation fan, and the like. In addition, in Fig. 1, the exhaust duct connected to the exhaust fan 5 is directly connected to the outside of the general house 1, but in the case of using the exhaust function of the heat exchange ventilator, the exhaust duct is temporarily connected to the heat exchange ventilator, and then Connected to general residence 1 outside. That is, the air passing through the exhaust duct performs heat exchange with the air passing through the air supply path of the heat exchange ventilator, and then is discharged to the outside of the general house 1 . The exhaust fan 5a is installed in the living room 2a, the exhaust fan 5b is installed in the living room 2b, the exhaust fan 5c is installed in the living room 2c, and the exhaust fan 5d is installed in the living room 2d.

Each exhaust fan 5 is configured so that the exhaust air volume can be set in a plurality of steps. Normally, each exhaust fan 5 is controlled to reach a preset exhaust air volume. Then, the exhaust air volume is controlled for each of the exhaust fans 5 a to 5 d based on user settings or values acquired by various sensors.

The conveying fans 3 a to 3 d are installed on, for example, a wall surface of the air-conditioning room 18 corresponding to the respective living rooms 2 a to 2 d. The air in the air-conditioning room 18 is delivered to the living room 2a via the delivery duct by the delivery fan 3a, delivered to the living room 2b via the delivery duct by the delivery fan 3b, delivered to the living room 2c via the delivery duct by the delivery fan 3c, and delivered to the living room 2c by the delivery fan 3d via the delivery duct. Pipes are delivered to chamber 2d. In addition, the delivery pipes connected to each living room are installed independently.

The circulation fan 6a is installed in the living room 2a, the circulation fan 6b is installed in the living room 2b, the circulation fan 6c is installed in the living room 2c, and the circulation fan 6d is installed in the living room 2d. A part of the air in each living room 2a-2d is sent to the air-conditioning room 18 through the circulation duct by the corresponding circulation fans 6a-6d. In addition, the circulation ducts connecting the air-conditioning room 18 and each living room may be installed independently, but a part of the circulation ducts, that is, a plurality of branch ducts may be merged midway to form a single circulation duct, and then connected to the air-conditioning room 18 .

The air conditioner 9 corresponds to an air conditioner, and controls the air conditioning of the air conditioning room 18 . The air conditioner 9 cools or heats the air in the air-conditioning room 18 so that the temperature of the air in the air-conditioning room 18 becomes a set target temperature (air-conditioning room target temperature).

Humidifier 16 humidifies the air in air-conditioning room 18 so that when the humidity of the air in air-conditioning room 18 is lower than a set target humidity (air-conditioning room target humidity), the humidity becomes the air-conditioning room target humidity. In addition, the humidifier 16 may also be incorporated in the air conditioner 9 , but in order to obtain a humidification capability corresponding to a plurality of living rooms 2 , it is desirable that the air conditioner 9 includes an independent humidifier 16 . Here, the air-conditioning room target humidity is defined as a predetermined humidity range defined by the lowest humidity as the lower limit and the highest humidity as the upper limit. In addition, the lowest humidity, the highest humidity, and the humidity handled in this embodiment are respectively expressed as relative humidity, and can be treated as absolute humidity by predetermined conversion processing. In this case, it is preferable to treat the entire process in the air-conditioning system including the humidity of the living room as absolute humidity.

The dehumidifier 17 dehumidifies the air in the air-conditioning room 18 so that when the humidity of the air in the air-conditioning room 18 is higher than a set target humidity (air-conditioning room target humidity), the humidity becomes the air-conditioning room target humidity. In addition, the dehumidifier 17 may also be built in the air conditioner 9, but in order to obtain the dehumidification capacity corresponding to the plurality of living rooms 2, it is desirable that the air conditioner 9 includes the independent dehumidifier 17.

The room temperature sensor 11a is installed in the room 2a, the room temperature sensor 11b is installed in the room 2b, the room temperature sensor 11c is installed in the room 2c, and the room temperature sensor 11d is installed in the room 2d. The room temperature sensors 11 a to 11 d are sensors that acquire the indoor temperatures of the corresponding rooms 2 a to 2 d and send them to the system controller 10 .

The room humidity sensor 12a is installed in the room 2a, the room humidity sensor 12b is installed in the room 2b, the room humidity sensor 12c is installed in the room 2c, and the room humidity sensor 12d is installed in the room 2d. The living room humidity sensor 12 is a sensor that acquires the indoor humidity (room humidity) of each of the corresponding living rooms 2 a to 2 d and sends it to the system controller 10 .

The air-conditioning room temperature sensor 14 is a sensor that acquires the temperature of the air in the air-conditioning room 18 and sends it to the system controller 10 . In addition, the air-conditioning room temperature sensor 14 may also be built in the air conditioner 9, but when it is built in the air conditioner 9, only the information around the air conditioner 9 (for example, near the air supply port) can be obtained. As described above, since the outside air is mixed with the air sent from each living room 2 , in order to obtain information on the air-conditioning room 18 as a whole, it is desirable to include the air-conditioning room 18 independently of the air conditioner 9 .

The air-conditioning room humidity sensor 15 is a sensor that acquires the humidity of the air in the air-conditioning room 18 , that is, the air-conditioning room humidity, and sends it to the system controller 10 . In addition, for the same reason as the air-conditioning room temperature sensor 14 , in order to obtain information on the entire air-conditioning room 18 , it is also desirable to include the air-conditioning room humidity sensor 15 independently of the air conditioner 9 .

The system controller 10 is a controller that controls the entire air conditioning system 20 . The system controller 10 communicates with the outside air through wireless communication with the fan 4, the exhaust fan 5, the delivery fan 3, the circulation fan 6, the room temperature sensor 11, the room humidity sensor 12, the air-conditioning room temperature sensor 14, the air-conditioning room humidity sensor 15, the air conditioner The humidifier 9, the humidifier 16 and the dehumidifier 17 are communicatively connected.

The system controller 10 sets the supply air volume of the external air introduction fan 4 and controls the external air introduction fan 4 and the exhaust fan 5 in conjunction with each other to achieve an air volume corresponding to the exhaust air volume of the exhaust fan 5 . Thereby, the ventilation of the general house 1 is performed by the first ventilation method.

In addition, the system controller 10 controls the air conditioner 9, humidifier 16, and dehumidifier 17 as air conditioners based on the temperature and humidity of the air in the air conditioning room 18 acquired by the air conditioning room temperature sensor 14 and the air conditioning room humidity sensor 15, so that The temperature and/or humidity of the air-conditioning room 18 become the air-conditioning room target temperature and/or the air-conditioning room target humidity set in the air-conditioning room 18 .

In addition, the system controller 10 compares the indoor temperature and/or indoor humidity of each living room 2 acquired by the living room temperature sensor 11 and the living room humidity sensor 12 with the target temperature (room target temperature) set for each of the living rooms 2a to 2d. Temperature) and/or target humidity (room target humidity), etc., set the air volume of the delivery fan 3 or the air volume of the circulation fan 6.

Thus, the air conditioned by the air-conditioning room 18 is sent to each living room 2 according to the air volume set in each delivery fan 3 , and the air in each living room 2 is sent to each living room 2 according to the air volume set in each circulation fan 6 . Air Conditioning Room 18. Therefore, the indoor temperature and/or the indoor humidity of each living room 2 are controlled to be the target room temperature and/or the target room humidity.

Here, the system controller 10, the external air introduction fan 4, the exhaust fan 5, the delivery fan 3, the circulation fan 6, the room temperature sensor 11, the room humidity sensor 12, the air-conditioning room temperature sensor 14, the air-conditioning room humidity sensor 15, the air conditioner The device 9, the humidifier 16, and the dehumidifier 17 are connected by wireless communication, thereby eliminating the need for a complicated wiring process. However, the whole of them may be configured to be communicable by wired communication, or the system controller 10 and a part thereof may be configured to be communicable by wired communication.

The input/output terminal 19 is communicably connected to the system controller 10 by wireless communication, and receives input of information required to construct the air conditioning system 20 and stores it in the system controller 10, or obtains and displays the information of the air conditioning system 20 from the system controller 10. status. Examples of the input/output terminal 19 include portable information terminals such as mobile phones, smartphones, and tablets.

In addition, the input/output terminal 19 does not necessarily have to be connected to the system controller 10 by wireless communication, and may be communicably connected to the system controller 10 by wired communication. In this case, the input/output terminal 19 can be realized by, for example, a wall-mounted remote controller.

Next, each function of the system controller 10 will be described with reference to FIG. 2 . FIG. 2 is a schematic functional block diagram of the system controller 10 .

The system controller 10 includes a room target humidity acquisition unit 54 , an air-conditioning room humidity control unit 55 , an air flow rate determination unit 40 , a fan air volume control unit 31 , and a storage unit 46 .

The living room target humidity acquisition unit 54 acquires the living room target humidity set in common with the entire living room 2 through the input/output terminal 19 . The room target humidity is set as a predetermined humidity range defined by the lowest humidity as the lower limit and the highest humidity as the upper limit. In the present embodiment, the target humidity of the living room matches the target humidity of the air-conditioning room. In addition, in the present embodiment, the user can set the target humidity of the living room, and it can also be set in advance as a fixed value in the air-conditioning system. The highest humidity and the lowest humidity acquired by the living room target humidity acquisition unit 54 or set in advance are stored in the storage unit 46 .

The air-conditioning room humidity control unit 55 uses the humidifier 16 and the dehumidifier 17 to control the humidity in the air-conditioning room to the air-conditioning room target humidity acquired by the living room target humidity acquisition unit 54 . Specifically, when the humidity of the air-conditioning room acquired by the air-conditioning room humidity sensor 15 is higher than the highest humidity constituting a predetermined humidity range, the dehumidifier 17 is operated. Moreover, when the humidity of the air-conditioning room acquired by the air-conditioning room humidity sensor 15 is lower than the minimum humidity, the humidifier 16 is operated.

The blowing air volume determination unit 40 includes a humidity determination unit 53 , a humidity difference comparison unit 56 , and a height determination unit 57 . Furthermore, the blowing air volume determination unit 40 determines the air blowing volume of the conveying fan 3 based on the indoor humidity of each living room acquired by the living room humidity sensor 12 and the humidity of the air-conditioning room 18 acquired by the air-conditioning room humidity sensor 15 . In addition, the flow of determination of the blowing air volume will be described later.

The humidity judging unit 53 judges whether the indoor humidity of each living room 2 is based on the indoor humidity of each living room 2 acquired by the living room humidity sensor 12 and the room target humidity acquired by the living room target humidity acquiring unit 54, that is, the air-conditioning room target humidity indicating a predetermined humidity range. within the specified humidity range.

The humidity difference comparator 56 calculates the difference between the indoor humidity of each living room acquired by the living room humidity sensor 12 and the humidity of the air-conditioning room 18 acquired by the air-conditioning room humidity sensor 15 . Specifically, for example, when the humidity of the living room 2a is 90% and the humidity of the air-conditioning room is 50%, the difference is 40. In addition, when calculating the difference, it is not necessary to obtain the difference in humidity expressed in %. For example, the difference can also be calculated based on the moisture content obtained based on the humidity, that is, as long as the difference between the humidity of the air-conditioning room and the humidity of the living room can be quantified That's it.

The level determination unit 57 determines the level of the indoor humidity of each living room acquired by the living room humidity sensor 12 relative to the humidity of the air-conditioning room 18 acquired by the air-conditioning room humidity sensor 15 . Specifically, for example, when the humidity of the living room 2a is 90% and the humidity of the air-conditioning room is 50%, it is determined that the humidity of the living room 2a is "higher" than 50% of the humidity of the air-conditioning room. On the other hand, when the humidity of the living room 2c is 30% and the humidity of the air-conditioning room is 50%, it is determined that the humidity of the living room 2c is "lower" than 50% of the humidity of the air-conditioning room. These judgments can be made for all the rooms, or only for rooms with humidity higher than the highest humidity and rooms with humidity lower than the lowest humidity.

The fan air volume control unit 31 controls the respective air volumes of the plurality of conveying fans 3 a to 3 d provided corresponding to each of the plurality of living rooms 2 a to 2 d to be the blowing air of each of the conveying fans 3 a to 3 d determined by the air blowing volume determining unit 40 . quantity. In addition, the fan air volume control unit 31 can control the circulation fans 6a to 6d, and detailed description thereof will be omitted here.

The storage unit 46 is a so-called memory that stores the highest humidity and the lowest humidity that are predetermined humidity ranges acquired by the room target humidity acquisition unit 54 or set in advance. In addition, the storage unit 46 is also used when it is necessary to store information such as numerical values for the control of the other system controller 10 .

Next, the air conditioning process executed by the system controller 10 will be described with reference to FIGS. 3 to 8C . Fig. 3 is a flowchart showing air conditioning processing. Fig. 4 is a flowchart showing humidity control processing in an air-conditioning room. FIG. 5 is a flowchart showing fan air volume setting processing. FIG. 6 is a flowchart showing air flow rate determination processing. 7A and 7B are diagrams showing an example of the relationship between the air-conditioning room target humidity, the air-conditioning room humidity, and the living room humidity. 8A, 8B, and 8C are diagrams showing another example of the relationship between the air-conditioning room target humidity, the air-conditioning room humidity, and the living room humidity.

As shown in FIG. 3 , the air-conditioning process executed by the system controller 10 is mainly composed of an air-conditioning room humidity control process S100 and a fan air volume setting process S200 , and is executed in the following order.

When the user executes the air-conditioning process, first, the system controller 10 executes the air-conditioning room humidity control process S100 shown in FIG. 4 .

In the air-conditioning room humidity control process S100, the system controller 10 acquires the target room humidity set by the input-output terminal 19 and stores it in the storage unit 46 (S101). Here, the target room humidity refers to the humidity at which the user feels comfortable, and is the humidity common to all the rooms. The target humidity of the living room is defined as a predetermined humidity range in which the lower limit is the lowest humidity and the upper limit is the highest humidity. This predetermined humidity range is the target humidity range of the air-conditioning room 18, that is, is the same as the target humidity of the air-conditioning room. The user sets, for example, the highest humidity to 65% and the lowest humidity to 45% on the input/output terminal 19, and the system controller 10 acquires the room target humidity input to the input/output terminal 19 via the room target humidity acquisition unit 54 as the air-conditioning room target humidity.

If the air-conditioning room target humidity is obtained, the air-conditioning room humidity control unit 55 maintains the humidity of the air-conditioning room 18 within the range of the air-conditioning room target humidity using the air-conditioning room humidity sensor 15, humidifier 16, and dehumidifier 17 (S102).

The maintenance of the target humidity in the air-conditioning room is specifically performed as follows. That is, when the air-conditioning room humidity obtained by the air-conditioning room humidity sensor 15 is higher than the maximum humidity, the dehumidifier 17 is operated. Moreover, when the air-conditioning room humidity acquired by the air-conditioning room humidity sensor 15 is lower than the minimum humidity, the humidifier 16 is operated. Considering the change in the humidity of the air-conditioning room caused by the air flowing into the air-conditioning room 18 after the humidity control process in the air-conditioning room, dehumidification is carried out on the premise of a predetermined humidity range to, for example, a humidity lower than the maximum humidity within a certain range (e.g. -5%). Moreover, it is also possible to humidify to, for example, a humidity higher than the minimum humidity within a certain range (for example, +5%) at the time of humidification.

Through the above processing, the humidity of the air-conditioning room 18 is maintained within a predetermined humidity range.

Next, the system controller 10 executes the fan air volume setting process S200 shown in FIG. 5 .

In the fan air volume setting process S200, the blowing air volume determination unit 40 acquires the humidity of the air-conditioning room via the air-conditioning room humidity sensor 15 (S201). In addition, the blowing air volume determination unit 40 acquires the living room humidity of each living room 2 via the living room humidity sensor 12 (S202). Then, the system controller 10 acquires the highest humidity and the lowest humidity which are predetermined humidity ranges from the storage unit 46 via the room target humidity acquisition unit 54 ( S203 ).

Next, the blown air volume determination unit 40 determines whether or not the room humidity of each room is within a predetermined humidity range through the humidity determination unit 53 (S203).

Here, if all the living rooms are within the predetermined humidity range, the process ends (S204 Yes→End).

In addition, as long as at least one room is not within the predetermined humidity range, the humidity difference comparison unit 56 calculates the difference between the room humidity and the air-conditioning room humidity of the corresponding room (room not within the humidity range) (S204 No→S205). Then, the level determination unit 57 determines whether the room humidity of the corresponding room is higher or lower than that of the air-conditioned room, that is, relative to the humidity of the air-conditioned room (S206). Here, as for the determination of the height, the humidity of the air-conditioning room can be compared with the humidity of the air-conditioning room acquired by the air-conditioning room humidity sensor 15 and the humidity of the living room. The height judging section 57 judges the height, and divides the living room 2 (rooms 2a to 2d) that are not within the prescribed range into a high-humidity room higher than the highest humidity and a low-humidity room lower than the lowest humidity, and compares them with the humidity difference comparing section 56. associated with the temperature difference. That is, in this process, the blowing air volume determination unit 40 can grasp the difference between the number of high-humidity rooms and low-humidity rooms and the humidity of each air-conditioning room.

When the above-mentioned processing is completed, the air flow rate determination unit 40 performs air flow rate determination processing (S300).

The air flow rate determination unit 40 executes the air flow rate determination process S300 shown in FIG. 6 . That is, in the blowing air volume determining process S300, first, the blowing air volume determining unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room.

Here, when there are only a plurality of low-humidity living rooms, the air flow rate of the living room with a large humidity difference is determined to be large (S301 Yes→S303). This processing will be described in detail with reference to FIG. 7A . In addition, Fig. 7A is an example in which only a plurality of low-humidity rooms exist. In addition, a in FIG. 7A indicates the living room 2a, b indicates the living room 2b, c indicates the living room 2c, d indicates the living room 2d, and the numerical values in the lower part indicate the living room humidity. In addition, the highest humidity was set to 65%, the lowest humidity was set to 45%, and the humidity in the air-conditioned room was set to 50%.

According to FIG. 7A , there are only two low-humidity rooms (room 2c, room 2d). Furthermore, the humidity difference (absolute value) between the living room 2c and the air-conditioning room humidity is 20%, and the humidity difference between the living room 2d and the air-conditioning room humidity is 30%. In this case, the air flow rate determination unit 40 sets the air flow rate of the delivery fan 3d corresponding to the room 2d having a large humidity difference higher than the air flow rate of the delivery fan 3c corresponding to the room 2c. Here, the blowing air volume can be defined as the blowing capacity or the operating gap of the conveying fan. For example, if the air blowing volume of the conveying fan 3 can be set in 10 stages from the small air blowing volume to the air blowing volume 1 to the air blowing volume 10, then here, the air blowing volume determination unit 40 sets the air blowing rate of the conveying fan 3d to 10 steps. The air volume is determined as the maximum air volume of 10. Furthermore, the blowing air volume determination unit 40 determines the air blowing volume of the conveying fan 3 c to be smaller than the conveying fan 3 d , for example, the air blowing volume 7 .

As a result, the air in the air-conditioned room flows into the living room 2c and the living room 2d, and the living room humidity of each living room gradually approaches within a predetermined humidity range. At this time, the humidity of the living room 2d with a large humidity difference from the air-conditioning room humidity, which feels slightly uncomfortable due to the difference in the air-conditioning room, improves faster than the humidity of the living room 2c, which has a smaller humidity difference from the air-conditioning room humidity than the living room 2d. That is, for a living room with a poor humidity environment, the blowing air volume determination unit 40 gives priority to improving the humidity of the living room.

In addition, at this time, the humidity of the air-conditioning room gradually decreases from 50% due to the inflow of dry air into the living room 2c and the living room 2d. Therefore, when the humidity is lower than the minimum humidity, the air-conditioning room humidity control unit 55 operates the humidifier 16 as necessary. , to maintain the humidity in the air-conditioning room within the specified humidity range.

In addition, the blowing air volume determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and when there are only a plurality of high-humidity rooms, similarly counts the number of rooms with a large humidity difference. The air volume is determined to be large (S301 No→S302 Yes→S303).

This processing will be described in detail with reference to FIG. 7B . In addition, Fig. 7B is an example in which only a plurality of high-humidity rooms exist.

According to FIG. 7B, there are only two high-humidity rooms (room 2a, room 2b). Furthermore, the humidity difference (absolute value) between the living room 2a and the air-conditioning room humidity is 40%, and the humidity difference between the living room 2b and the air-conditioning room humidity is 30%. In this case, the air flow rate determination unit 40 sets the air flow rate of the conveying fan 3a corresponding to the room 2a having a large humidity difference higher than the air flow rate of the transport fan 3b corresponding to the living room 2b. That is, here, the air blowing amount determination unit 40 determines the air blowing amount of the conveying fan 3 a to be the air blowing amount 10 which is the maximum value. Furthermore, the blowing air volume determination unit 40 determines the air blowing volume of the conveying fan 3 b to be smaller than the conveying fan 3 b, for example, the air blowing volume 7 .

As a result, the air in the air-conditioned room flows into the living room 2a and the living room 2b, and the living room humidity of each living room gradually approaches within a predetermined humidity range. At this time, the humidity of the living room 2a with a large humidity difference from the air-conditioning room humidity, which is slightly uncomfortable due to the difference in the air supply volume, improves faster than the humidity of the living room 2b with a smaller humidity difference from the air-conditioning room humidity than the living room 2a. That is, for a living room with a poor humidity environment, the blowing air volume determination unit 40 gives priority to improving the humidity of the living room.

In addition, at this time, the humidity of the air-conditioning room gradually rises from 50% due to the inflow of humid air into the living room 2a and the living room 2b. Therefore, when the humidity is higher than the maximum humidity, the air-conditioning room humidity control unit 55 operates the dehumidifier 17 as necessary. , to maintain the humidity in the air-conditioning room within the specified humidity range.

In addition, the blowing air volume determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and when there are both high-humidity rooms and low-humidity rooms, the number of rooms with a small humidity difference is counted. The air supply volume is set to be large (S302 No→S304 Yes→S305).

This process will be described in detail with reference to FIGS. 8A , 8B, and 8C. In addition, Fig. 8A is an example in which only a plurality of low-humidity rooms exist. In addition, the representation in FIG. 8A is the same as that in FIGS. 7A and 7B.

According to FIG. 8A , there are a living room 2c which is a low-humidity room and a living room 2a which is a high-humidity room. Furthermore, the humidity difference between the living room 2c and the air-conditioning room humidity is 20%, and the humidity difference between the living room 2a and the air-conditioning room humidity is 40%. In this case, air flow rate determination unit 40 sets the air flow rate of conveying fan 3a corresponding to room 2a with large humidity difference smaller than the air flow rate of transport fan 3c corresponding to room 2c with small humidity difference. In other words, the air flow rate determination unit 40 sets the air flow rate of the delivery fan 3c corresponding to the room 2c with a small humidity difference higher than the air flow rate of the delivery fan 3a corresponding to the room 2a with a large humidity difference. Specifically, here, the air blowing volume determination unit 40 determines the air blowing volume of the transport fan 3 c to be the maximum air blowing volume 10 . Furthermore, the air blowing volume determination unit 40 determines the air blowing volume of the conveying fan 3 a to be smaller than that of the conveying fan 3 c , for example, the air blowing volume 5 .

As a result, the air in the air-conditioned room flows into the living room 2a and the living room 2c, and the living room humidity of each living room gradually approaches within a predetermined humidity range. At this time, as shown in FIG. 8B , the humidity of the living room 2c with a small humidity difference is first improved by the difference in the blowing air volume.

Here, the difference from S303 is that by controlling the inflow of air from the two living rooms, fluctuations in humidity in the humidity of the air-conditioning room are suppressed to the minimum. That is, the inflow of air from a low-humidity room with a small humidity difference to the air-conditioning room is set larger than the inflow of air from a high-humidity room with a large humidity difference into the air-conditioning room, thereby reducing the amount of moisture to the air-conditioning room. The inflow and outflow controls are (ideally) equivalent. This can suppress fluctuations in the humidity of the air-conditioning room, so that the operation of the humidifier 16 or the dehumidifier 17 can be suppressed, and energy-saving control can be realized. In addition, the efficient use of the air-conditioning room can be realized in terms of humidity, and the miniaturization of the air-conditioning room can be realized.

In addition, the air flow rate determining unit 40 may set the air flow rate of the conveying fan 3c corresponding to the room 2c with a small humidity difference to the air flow rate of the transport fan 3a corresponding to the room 2a with a large humidity difference. Specifically, the air blowing volume determination unit 40 determines the air blowing volume of the conveying fan 3 c and the air blowing amount of the conveying fan 3 a to be 10 air blowing volumes, for example. In this case, as shown in FIG. 8C, first, the humidity of the living room 2c is improved. At this time, while the humidity of the living room 2c is improved, the low-humidity air of the living room 2c and the high-humidity air of the living room 2a cancel out the humidity, so fluctuations in the humidity of the air-conditioning room can be suppressed. In addition, since the humidity of the living room 2a is high, it is expected that the humidity of the air-conditioning room will rise slightly, but the humidity control unit 55 of the air-conditioning room may respond with the dehumidifier 17 as necessary. Even this processing can contribute to energy-saving control and downsizing of the air conditioner.

The blowing air volume determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and indicates the presence of one low-humidity room or High humidity room. In this case, the blowing air volume determination unit 40 blows air at a predetermined air volume to the applicable low-humidity room or high-humidity room, thereby allowing the humidity of the room to transition to a predetermined humidity range (S304 No→S306).

The air-conditioning process has been described above, but after the air-conditioning process is executed for the first time, the air-conditioning process is repeatedly performed independently of the air-conditioning room humidity control process S100 and the fan air volume setting process S200 .

The air-conditioning system and the system controller of the present invention have been described above, but the above-mentioned embodiment is merely an example and is not limited thereto.

For example, the circulation fans 6a to 6d and the delivery fans 3a to 3d communicate through ducts connecting the living room and the air-conditioning room. However, the circulation fans 6a to 6d are not necessarily connected by ducts, and spaces such as corridors connecting rooms can also be regarded as ducts. In this case, the air in the living room is sent from the living room to the corridor by the circulation fans 6a to 6d. The air sent to the living room in the corridor is taken into the air-conditioning room 18 communicating with the corridor. The intake into the air-conditioning room 18 may be performed by newly including a circulation fan on the wall surface of the air-conditioning room 18 facing the corridor, or by depressurizing the air-conditioning room without using a circulation fan. Even with this structure, the cycle efficiency is expected to decrease compared to the case of connecting by ducts, which can contribute to the air conditioning system.

Next, an air-conditioning room 18 according to a first embodiment of the present invention will be described with reference to FIGS. 9 , 10 , and 11 . 9 and 10 are schematic diagrams of the air-conditioning room 18 according to the first embodiment. FIG. 9 is a schematic diagram of the air-conditioning room when the air-conditioning room is divided into three partitions. FIG. Schematic diagram of an air-conditioning room in the case of partitioning. Fig. 11 is a schematic functional block diagram of the system controller when the air-conditioning room is divided into three sections. In addition, in FIG. 11 , a first space humidity calculation unit 58 is added to the schematic functional block diagram shown in FIG. 2 .

In addition, in the above-mentioned FIG. 1 , the air-conditioning room 18 is not partitioned, that is, it is in the same space, and its temperature and humidity are controlled by the air conditioner 9 , humidifier 16 and dehumidifier 17 . On the other hand, in FIGS. 9 and 10 , efficient dehumidification/humidification can be realized by dividing the air-conditioning room 18 into sections.

Specifically, as shown in FIG. 9 , dehumidification, temperature control, and humidification are performed in separate spaces. For example, as shown in FIG. 9 , the air-conditioning room 18 is divided into three independent spaces of a first space 22 , a second space 23 , and a third space 24 by a partition plate 21 . In this case, the air conditioner 9, the humidifier 16, the dehumidifier 17, and the like are also controlled by the system controller 10 in the same manner as above. In addition, a first space 22 , a second space 23 , and a third space 24 are sequentially arranged from upstream to downstream, and the air in each space is blown downstream by the delivery fan 3 .

The partition board 21 has functions of separating the first space 22 and the second space 23 and the second space 23 and the third space 24 , and is formed of a wooden board or a gypsum board. In addition to the panels used, the partition panel 21 can further prevent heat and humidity transfer between the spaces by bonding heat insulating panels together. In addition, the partition plate 21 is provided with a space connection opening 25 of a round hole or a square hole on a part of the plate surface. Thereby, the first space 22 and the second space 23 and the second space 23 and the third space 24 become independent spaces that can be ventilated to each other via the space connection opening 25 .

In the absence of the partition plate 21, the space connecting opening 25 has an opening area of, for example, 30% or less, more preferably 20% or less of the area of the surface where the first space 22 and the second space 23 meet. area. The reason is that if the space connection opening 25 is too large, the contribution to the dehumidification and humidification efficiency improvement decreases, and if it is too small, the pressure loss increases and may adversely affect the ventilation efficiency between spaces. In addition, here, the space connecting opening 25 is provided as a simple opening, but by providing a forced air blowing fan such as a duct fan in the opening, the air blowing efficiency from the upstream independent space to the downstream independent space can be improved.

The first space 22 is provided with a first air supply opening 26 for supplying indoor air and a second air supply opening 27 for supplying outdoor air upstream, and a space connection opening 25 with the second space 23 is provided downstream. . In addition, the first space 22 is provided with a dehumidifier 17 , a first space temperature sensor 28 , and a first space humidity sensor 29 . With this structure, the indoor air from the first air supply opening 26 and the outdoor air from the second air supply opening 27 are mixed in the first space 22 . The mixed air usually contains more fresh outside air than the air inside the room. The air sent from the delivery fans 3a to 3d returns to the first space 22 via the living rooms 2a to 2d, so the air in the room is at the target temperature set in the system controller 10, the temperature and humidity close to the target humidity. On the other hand, for example, in summer or in a high-temperature and high-humidity environment during rainy season, the outdoor air has a high temperature and high humidity relative to the set target temperature and target humidity. As described above, since more outdoor air is supplied to the first space 22 than indoor air, the first space 22 becomes a high-temperature and high-humidity environment. When the mixed air in the first space 22 is higher than the air-conditioning room target humidity of the air-conditioning room 18, the first space 22 is dehumidified by the dehumidifier 17 to reach the air-conditioning room target humidity, which will be described in detail later. The dehumidified air is blown to the second space 23 through the space connection opening 25 .

The first space temperature sensor 28 is a sensor that acquires the temperature of the air in the first space 22 and sends it to the system controller 10 . As mentioned above, the outside air is mixed with the air delivered from each living room 2, so it is desirable that the first space 22 is provided with a first space temperature sensor 28 downstream, that is, near the space connection opening 25, so as to obtain the temperature as a whole of the first space 22. Information.

The first space humidity sensor 29 is a sensor that acquires the humidity of the air in the first space 22 , that is, the humidity of the first space 22 , and sends it to the system controller 10 . Also, for the same reason as the first space temperature sensor 28 , it is desirable to install a first space humidity sensor 29 downstream, that is, near the space connection opening 25 , in order to obtain information on the entire first space 22 .

The second space 23 is provided with a space connection opening 25 with the first space 22 upstream, and a space connection opening 25 with the third space 24 is provided downstream. In addition, the air conditioner 9 is arranged in the second space 23 . With this configuration, the air dehumidified in the first space 22 is cooled or heated by the air conditioner 9 in the second space 23 so that the temperature of the air in the second space 23 becomes the set air-conditioning room target temperature. Then, the cooled or heated air is blown to the third space 24 through the space connection opening 25 with the third space 24 .

The third space 24 is provided with a space connection opening 25 with the second space 23 upstream, and conveying fans 3 a to 3 d are provided downstream. In addition, the humidifier 16 is arranged in the third space 24 . Furthermore, in the third space 24, the air-conditioning room temperature sensor 14 and the air-conditioning room humidity sensor 15 are arranged downstream, that is, near the conveying fans 3a to 3d. With this configuration, the air cooled or heated in the second space 23 is humidified by the humidifier 16 in the third space 24 so that its humidity becomes the target humidity of the air-conditioning room when it is lower than the target humidity of the air-conditioning room. Then, the humidified air is sent to the respective living rooms 2a to 2d via the sending fans 3a to 3d.

With this configuration, the control of the target temperature of the air-conditioning room and the control of the target humidity of the air-conditioning room can be separately performed in independent spaces, so that efficient dehumidification and humidification can be performed. Next, the specific flow and effect of dehumidification and humidification will be described.

For example, in the high-temperature and high-humidity environment of summer or rainy season, the air in the air-conditioning room 18 is dehumidified or cooled. First, the air-conditioning room humidity control unit 55 calculates the difference between the air-conditioning room target humidity and the humidity of the air-conditioning room 18 , that is, the humidity of the third space 24 . And, when the humidity of the third space 24 is higher than the target humidity of the air-conditioning room, dehumidification is performed by the dehumidifier 17 provided in the first space 22 . The air dehumidified in the first space 22 is blown to the second space 23 . In the second space 23 , when the temperature of the air in the second space 23 is higher than the set air-conditioning room target temperature, the air conditioner 9 installed in the second space 23 performs cooling. Here, the humidity controlled in the first space 22 is changed by cooling in the second space 23 . In contrast, in this structure, the air in the first space 22 is controlled by the air-conditioning room humidity control unit 55 to be lower than the humidity of the transported air blown to the outside of the air-conditioning room 18 via the transport fan 3 (in this case, relative humidity). Humidity) below the specified dehumidification humidity. That is, the 1st space humidity calculation part 58 estimates the cooling by the air conditioner 9, and calculates (counts back) the humidity which the 1st space 22 should reach.

Specifically, the first space humidity calculation unit 58 calculates the temperature of the first space 22 by The following procedure calculates the humidity (relative humidity in this case) to which the air of the first space 22 is to reach.

First, the absolute humidity, which is the moisture content of the air to be fed, is calculated from the conditions of the set target humidity of the air to be fed (relative humidity in this case) and the set target temperature of the air to be fed. In summer or rainy season, after the second space 23 is cooled as described above, air is sent from the third space 24 to the respective living rooms 2a to 2d. That is, by determining the absolute humidity in the first space 22, the air sent to the respective living rooms 2a to 2d becomes the target absolute humidity. The first space humidity calculation unit 58 calculates the absolute humidity of the conveyed air, and then detects the temperature of the first space 22 . Thereby, the humidity (relative humidity in this case) at the temperature of the first space 22 to be reached can be calculated. In summer or rainy season, the temperature of the second space 23 is cooled by the air conditioner 9 relative to the temperature of the first space 22 as required. Therefore, the humidity of the air in the first space 22 (relative humidity in this case) is smaller than the humidity of the air in the second space 23 (relative humidity in this case). Therefore, the humidity (relative humidity in this case) of the air in the first space 22 is controlled to be a dehumidification humidity lower than the humidity (relative humidity in this case) of the conveyed air.

As mentioned above, in summer or rainy season, high-temperature and high-humidity air is blown into the first space 22 . As far as air is concerned, the higher the temperature, the more saturated water vapor, and the more water it can contain. If dehumidification is performed in this case, a large amount of moisture can be removed from the air only by slightly lowering the temperature of the air in the heat exchanger provided in the dehumidifier 17 . That is, it is possible to efficiently dehumidify the air.

Also, during the rainy season, when the air conditioner 9 and the dehumidifier 17 are installed in the same space of the air conditioning room 18, the temperature difference between the outside of the air conditioner 9 and the air in the air conditioning room 18 is small, and the heat is turned off. In this case, only the dehumidifier 17 operates, the air is radiated by the dehumidifier 17, the temperature of the air-conditioning room 18 becomes higher than the outdoor temperature, and the air is sent to the respective living rooms 2a to 2d. However, dehumidification is performed first in the first space 22, and the air heated by the heat dissipation of the dehumidifier 17 is blown to the air conditioner 9, and the air conditioner 9 performs a cooling operation to adjust to the set target temperature of the air-conditioned room. In addition, the air-conditioning room 18 is expected to be a relatively small space. Therefore, when the air conditioner 9 and the dehumidifier 17 are installed in the same space of the air-conditioning room 18, the cooling of the air by the air conditioner 9 and the heating of the air by the heat radiation from the dehumidifier 17 are performed at the same time. Control to the set target temperature. However, since the air-conditioning room 18 is partitioned, heat radiation from the dehumidifier 17 can be separated from the second space 23 where the air-conditioning unit 9 exists, so it is easy to control to the set air-conditioning room target temperature and air-conditioning room target humidity.

Also, for example, in the case of a low-temperature and low-humidity environment in winter, the air in the air-conditioning room 18 is heated and humidified. First, the air-conditioning room humidity control unit 55 detects the humidity of the air in the first space 22 to determine whether it is a dehumidification target, but winter air with sufficiently low humidity is not a dehumidification target. That is, in the first space 22 , only the indoor air from the first air supply opening 26 and the outdoor air from the second air supply opening 27 are mixed.

Next, when the air in the second space 23 is lower than the set air-conditioning room target temperature, it is heated to the air-conditioning room target temperature set by the air conditioner 9 . In this case, the humidity (relative humidity in this case) of the air in the second space 23 is greatly reduced by heating. The air heated in the second space 23 is sent to the third space 24 in a state of satisfying the condition of the target temperature of the air-conditioning room.

In the third space 24 , the air-conditioning room humidity control unit 55 calculates the difference between the set air-conditioning room target humidity and the humidity of the third space 24 . Furthermore, when the humidity of the third space 24 is lower than the target humidity of the air-conditioning room, the air-conditioning room humidity control unit 55 performs humidification by the humidifier 16 provided in the third space 24 . Thereby, the air sent from the sending fans 3 a to 3 d in the third space 24 becomes the set air-conditioning room target temperature and air-conditioning room target humidity.

In this structure, the air heated by the air conditioner 9 is blown into the third space 24 . Furthermore, the higher the temperature of the air, the more moisture can be contained, that is, the higher the absolute humidity can be set. Accordingly, the air in the third space 24 can efficiently absorb moisture from the humidifier 16 . That is, the air in the third space 24 can be more efficiently humidified to the set target humidity of the air-conditioning room, and can be sent from the sending fans 3 a to 3 d to the respective living rooms 2 .

As mentioned above, the structure which divided the space of the air-conditioning room 18 of the air-conditioning system of this invention into three partitions was demonstrated, but the said embodiment is an example, and is not limited to this.

For example, as shown in FIG. 10 , the second space 23 may also be used as the space serving as the third space 24 , that is, the second-third space 30 may be used. In other words, the space for cooling or heating the air and the space for humidifying may be the same space.

In the high-temperature and high-humidity environment during summer or rainy season, the air is dehumidified in the first space 22 and cooled in the second-third space 30 as in the case of the above-mentioned three divisions. In addition, in the case of a low-temperature and low-humidity environment in winter, heating and humidification are simultaneously performed in the second-third spaces 30 . In this structure, the air whose temperature is lower than that of the air-conditioning room is blown from the first space 22 to the second-third space 30, and the efficiency of humidifying the air is lower than that of the above-mentioned case of dividing into three partitions. However, the volume of the humidification space can be set larger than the third space 24 by setting it as the second-third space 30 . That is, the amount of air with high humidity after humidification is larger in the second-third space 30 than in the third space 24, and can be more efficiently humidified to the set target humidity of the air-conditioning room. Furthermore, the number of partition plates 21 can be reduced from two to one, and the cost of the air-conditioning room 18 can be reduced.

In addition, although the living room was shown in the above-mentioned embodiment, a living room does not necessarily have to be occupied, and it can be regarded as one space. That is, as long as the corridor or the kitchen is also separated to some extent, it can be regarded as one space, which is equivalent to a living room.

In addition, the air-conditioning system of the present invention can be applied to multiple houses such as single-family houses and apartments. However, when an air-conditioning system is applied to a multi-family house, one system corresponds to one household, and one household is not defined as one living room.
