Description

How to control air conditioning systems, controllers, and blowers

This disclosure relates to an air conditioning system, a controller, and a control method for a blower.

Conventionally, in a building such as an office building, the air in the perimeter zone (area near the window or wall) in the room and the air in the interior zone (area in the center of the room) are harmonized by using different air conditioners. ing.

For example, in winter, the air conditioner for the perimeter zone is heated to warm the perimeter zone, while the air conditioner for the interior zone is cooled to cool the interior zone. The reason for cooling the interior zone in winter is that people, luminaires, and electronic devices raise the temperature of the interior zone.

When the heating operation and the cooling operation are performed simultaneously in the room in this way, a mixing loss (mixing loss of heating and cooling) occurs in which both the heating load and the cooling load increase.

In order to reduce such mixing loss, for example, Japanese Patent Application Laid-Open No. 56-157747 (Patent Document 1) provides a hanging wall on the ceiling surface.

Japanese Unexamined Patent Publication No. 56-157747

If a hanging wall is provided on the ceiling surface, warm air will stay near the hanging wall on the perimeter zone side. Therefore, in the perimeter zone, the circulation of warm air due to convection is stagnant.

When the circulation of warm air is stagnant in this way, the room temperature in the perimeter zone becomes non-uniform. In addition, an unfavorable phenomenon called "cold draft" (a phenomenon in which warm air in a room is cooled by touching a cold window glass and descends to the floor surface) occurs. Furthermore, since the amount of reduction in the heating load does not increase, it is difficult to significantly reduce the mixing loss.

The present disclosure provides a control method for an air conditioning system capable of smoothing the circulation of warm air in a perimeter zone, a controller constituting the air conditioning system, and a blower constituting the air conditioning system.

According to certain aspects of the present disclosure, the air conditioning system draws in air from the perimeter zone through a first air control port on the ceiling of the perimeter zone in the interior of the building, and the sucked air is the first air control. The blower for blowing out to the perimeter zone from the second air control port provided on the outer wall side of the building rather than the mouth, and the first air conditioner that harmonizes the air in the perimeter zone are operating for heating and indoors. A controller for driving the blower is provided, provided that the second air conditioner that harmonizes the air in the interior zone is in cooling operation.

According to another aspect of the present disclosure, the controller draws in air from the perimeter zone from a first air control port provided on the ceiling of the perimeter zone in the interior of the building, and the sucked air is taken into the first air control port. It controls the blower for blowing out to the perimeter zone from the second air control port provided on the outer wall side of the building. The controller is provided on the condition that the first air conditioner that harmonizes the air in the perimeter zone is operating for heating and the second air conditioner that harmonizes the air in the interior zone of the room is operating for cooling. Drive the blower.

According to still another aspect of the present disclosure, the control method of the blower is such that the first air conditioner that harmonizes the air in the perimeter zone in the building is heated and operates and harmonizes the air in the interior zone of the room. The perimeter is subject to the step of detecting that the second air conditioner is in the cooling operation and the condition that the first air conditioner is in the heating operation and the second air conditioner is in the cooling operation. The air in the perimeter zone is sucked in from the first air-conditioning port provided on the ceiling of the zone, and the sucked air is taken in from the second air-conditioning port provided on the outer wall side of the building from the first air-conditioning port. It is equipped with a step to drive the blower so that it blows into the perimeter zone.

According to the present disclosure, it is possible to smooth the circulation of warm air in the perimeter zone.

Hereinafter, embodiments will be described with reference to the drawings. In the following description, the same parts are designated by the same reference numerals. Their names and functions are the same. Therefore, the detailed description of them will not be repeated.

<A. Outline of technical idea ＞
In the present embodiment, the warm air in the perimeter zone is circulated in the perimeter zone by a blower. The drive of the blower is performed by the controller.

Specifically, the ceiling of the perimeter zone inside the building is provided with a first air control port (specifically, a suction port (intake port)). Further, on the ceiling of the perimeter zone, a second air control port (specifically, an air outlet (exhaust port)) is provided on the outer wall side of the building with respect to the first air control port. The blower sucks the air in the room from the first air control port and blows the sucked air into the perimeter zone from the second air control port.

More specifically, the controller is provided that the air conditioner that harmonizes the air in the perimeter zone is operating for heating and the air conditioner that harmonizes the air in the interior zone adjacent to the perimeter zone is operating for cooling. , Drive the blower.

By such processing, the circulation of warm air in the perimeter zone is promoted. Therefore, the perimeter zone can be heated uniformly. In addition, since the second air control port (outlet) is on the outer wall side of the building from the first air control port (suction port), cold draft (warm air in the room is cooled by touching the cold window glass). , The phenomenon of descending to the floor surface) can be reduced.

Furthermore, since warm air is taken in from the first air control port (suction port) provided on the ceiling of the perimeter zone, it is possible to prevent the warm air from flowing into the interior zone. Therefore, it is possible to increase the heating efficiency and the cooling efficiency at the same time. Therefore, the mixing loss can be significantly reduced.

Hereinafter, a specific example of such a configuration will be described with reference to the drawings.
<B. System configuration>
FIG. 1 is a cross-sectional view showing a cross section of a building. The building is typically an office building.

With reference to FIG. 1, the interior 940 of the building 900 is conceptually divided into a perimeter zone 941 and an interior zone 942. The perimeter zone 941 and the interior zone 942 are adjacent to each other.

In this example, the outer wall 901 side (or window 902 side) of the building 900 is the perimeter zone 941 with respect to the virtual line L. The interior zone is on the central side of the building from the virtual line L. The "perimeter zone" is typically an area from the window 902 to the vicinity of 5 m. However, since the perimeter zone is determined by the structure of the building 900 and the like, the distance from the window 902 is not limited to 5 m.

An air conditioner 501 that harmonizes the air in the perimeter zone 941 is installed in the perimeter zone 941. That is, the air conditioner 501 for the perimeter zone 941 is installed in the perimeter zone 941.

Specifically, the air conditioner 501 is installed on the floor surface 970 near the window 902 side. The air conditioner 501 (in this example, an indoor unit) sucks in air near the floor surface 970 from the suction port 510 and blows air above the air conditioner 501 from the air outlet 530. In the example of FIG. 1, the underfloor 980 is formed under the floor surface 970, but the underfloor 980 may not be present.

An air conditioner 601 that harmonizes the air in the interior zone 942 is installed in the attic 960. That is, an air conditioner 601 for the interior zone 942 is installed in the attic 960. In the present embodiment, the air conditioner 601 is installed in the space above the interior zone 942 in the attic 960. The attic 960 is a space formed by providing the ceiling 950.

The ceiling 950 in the interior zone 942 is provided with a suction port 610, a duct 620, and an outlet 630. The suction port 610 is provided on the window 902 side of the air outlet 630.

The air conditioner 601 (in this example, an indoor unit) sucks air from the suction port 610 and blows out air from the outlet 630. Specifically, the air sucked from the suction port 610 passes through the duct 620 and is sucked into the air conditioner 601. Further, the air discharged from the air conditioner 601 passes through the duct 620 and is discharged from the outlet 630 to the interior zone 942.

The ceiling 950 in the perimeter zone 941 is provided with a suction port 210, a duct 220, and an outlet 230. The outlet 230 is provided on the window 902 side of the suction port 210.

The air conditioning system 1 according to the present embodiment includes a controller 110, a temperature sensor 120, a temperature sensor 130, an operating device 140, and a blower 150. The controller 110 is communicably connected to the temperature sensor 120, the temperature sensor 130, the operating device 140, and the blower 150.

The blower 150 is installed behind the ceiling 960. In the present embodiment, the blower 150 is installed in the space above the perimeter zone 941 in the attic 960.

The blower 150 sucks in air from the suction port 210 and blows out air from the outlet 230. Although the details will be described later, the air sucked from the suction port 210 flows through the duct 220 and then blows out from the outlet 230 toward the perimeter zone 941.

The temperature sensor 120 detects (measures) the temperature of the perimeter zone 941. In this example, the temperature sensor 120 is installed near the outlet 530 of the air conditioner 501. Therefore, in this example, the temperature sensor 120 detects the temperature in the perimeter zone 941 near the outlet 530 of the air conditioner 501.

The reason why the temperature sensor 120 is installed near the outlet 530 of the air conditioner 501 is that the controller 110 can accurately determine whether or not the air conditioner 501 is in heating operation. However, the installation position of the temperature sensor 120 is not limited to the vicinity of the outlet 530 of the air conditioner 501.

The temperature sensor 130 detects the temperature of the interior zone 942. In this example, the temperature sensor 130 is installed near the air outlet 630 of the air conditioner 601. Therefore, in this example, the temperature sensor 130 detects the temperature in the interior zone 942 near the air outlet 630 of the air conditioner 601.

The reason why the temperature sensor 130 is installed near the outlet 630 of the air conditioner 601 is that the controller 110 can accurately determine whether or not the air conditioner 601 is in cooling operation. However, the installation position of the temperature sensor 130 is not limited to the vicinity of the outlet 630.

The temperature sensors 120 and 130 notify the controller 110 of the detection result. Specifically, the temperature sensors 120 and 130 transmit an electric signal (information indicating the temperature) to the controller 110.

In this example, the controller 110 is installed behind the ceiling 960. However, the installation location of the controller 110 is not limited to the attic 960.

The controller 110 determines the temperature near the outlet 530 of the air conditioner 501 based on the voltage value of the electric signal received from the temperature sensor 120. The controller 110 determines whether or not the air conditioner 501 is in the heating operation based on the temperature near the outlet 530 of the air conditioner 501. For example, if the temperature near the outlet 530 of the air conditioner 501 is equal to or higher than a predetermined threshold value (for example, 35 degrees), the controller 110 determines that the air conditioner 501 is in heating operation.

The controller 110 determines the temperature near the outlet 630 of the air conditioner 601 based on the voltage value of the electric signal received from the temperature sensor 130. The controller 110 determines whether or not the air conditioner 601 is in the cooling operation based on the temperature near the air outlet 630 of the air conditioner 601. For example, if the temperature near the air outlet 630 of the air conditioner 601 is equal to or lower than a predetermined threshold value (for example, 20 degrees), the controller 110 determines that the air conditioner 601 is in cooling operation.

As described above, in the controller 110, the air conditioner 501 for the perimeter zone 941 is in heating operation based on the detection result by the temperature sensor 120 and the detection result by the temperature sensor 130, and the air for the interior zone 942 is operated. It is detected that the air conditioner 601 is in cooling operation.

The controller 110 controls the drive of the blower 150. The controller 110 drives the blower 150 on condition that the air conditioner 501 is in the heating operation and the air conditioner 601 for the interior zone is in the cooling operation. Specifically, the controller 110 sends a drive command for driving the blower 150 to the blower 150. The drive of the blower 150 means the drive of a member for blowing air (for example, rotation of wings).

The operation device 140 includes a display unit 141 and an operation unit 142. The operating device 140 is used by the user of the air conditioning system 1 to manually control the start and stop of the blower 150. As described above, in the air conditioning system 1, it is possible to automatically control the blower 150 by the controller 110 and manually control the blower 150 by using the operating device 140.

The operation unit 142 is typically an operation button. When the operation unit 142 receives the user operation while the blower 150 is stopped, the controller 110 drives (forced operation) the blower 150. When the operation unit 142 receives the user operation while the blower 150 is in operation, the controller 110 stops the blower 150.

The display unit 141 displays various information. For example, the display unit 141 displays the operating state of the blower. The display unit 141 displays, for example, that forced operation is being performed.

By the way, the controller 110 detects that "the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation" based on the difference in temperature detected by the two temperature sensors 120 and 130. You may. Specifically, when the detection result (temperature) by the temperature sensor 130 is lower than the detection result (temperature) by the temperature sensor 120 by a predetermined threshold value or more, the controller 110 "is operating the air conditioner 501 for heating. Moreover, it may be determined that the air conditioner 601 is in cooling operation. " As the threshold value, for example, a value between 10 degrees and 20 degrees can be used.

<C. Air flow when driving the feeder>
In the following, it is assumed that the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation.

FIG. 2 is a diagram for explaining the air flow in the room 940 when the blower 150 is being driven.

With reference to FIG. 2, the air (that is, warm air) blown out from the air outlet 530 of the air conditioner 501 proceeds in the direction of the arrow 51. After that, the warm air diffuses and proceeds in the direction of arrow 52 as a whole. Since the blower 150 is driven, warm air is subsequently sucked from the suction port 210 (see arrow 53).

The sucked warm air is blown out from the outlet 230 toward the perimeter zone 941 by the blower 150. The outlet 230 is provided in the vicinity of the window 902. Therefore, the warm air blown out from the outlet 230 goes in the direction of the window 902 (see arrow 54).

The air conditioner 501 sucks the warm air flowing from the outlet 230 along the window 902 from the suction port 510. The air conditioner 501 sucks not only the warm air blown out from the outlet 230 but also other air near the floor surface 970 (for example, air in which warm air and cold air are mixed) (see arrow 55).

The air (that is, cold air) blown out from the air outlet 630 of the air conditioner 601 proceeds in the direction of the arrow 61. After that, the cold air diffuses and travels in the direction of arrow 62 as a whole. As shown by the arrow 63, air is sucked from the suction port 610 and sent to the air conditioner 601.

As described above, by driving the blower 150, the circulation of warm air in the perimeter zone 941 is promoted. Therefore, the perimeter zone 941 can be heated uniformly as compared with the case where the blower 150 is not driven. Further, since the air outlet 230 is located on the outer wall 901 side (that is, the window 902 side) of the building 900 with respect to the suction port 210, a large amount of warm air is supplied to the window 902 side. Therefore, cold draft can be reduced.

Further, since the warm air is sucked from the suction port 210 provided in the ceiling 950 of the perimeter zone 941, it is possible to prevent the warm air from flowing into the interior zone 942. Therefore, it is possible to increase the heating efficiency and the cooling efficiency at the same time. Therefore, according to the air conditioning system 1, the mixing loss of heating and cooling can be significantly reduced.

<D. Functional configuration>
FIG. 3 is a functional block diagram mainly for explaining the functional configuration of the controller 110.

With reference to FIG. 3, the controller 110 includes a temperature information acquisition unit 111, a temperature information acquisition unit 112, a determination unit 113, a command generation unit 114, a communication IF (Interface) unit 115, and a transmission unit 116. Be prepared.

The temperature information acquisition unit 111 receives the electric signal transmitted from the temperature sensor 120. The temperature information acquisition unit 111 determines the temperature in the vicinity of the temperature sensor 120 based on the voltage value of the electric signal.

The temperature information acquisition unit 112 receives the electric signal transmitted from the temperature sensor 130. The temperature information acquisition unit 112 determines the temperature in the vicinity of the temperature sensor 130 based on the voltage value of the electric signal.

In this way, the controller 110 acquires the temperature information from the temperature sensor 120 and the temperature information from the temperature sensor 130.

The determination unit 113 determines whether or not the air conditioner 501 in the perimeter zone 941 is in heating operation based on the temperature information acquired by the temperature information acquisition unit 111. Further, the determination unit 113 determines whether or not the air conditioner 601 in the interior zone 942 is in heating operation based on the temperature information acquired by the temperature information acquisition unit 112. The determination unit 113 notifies the command generation unit 114 and the communication IF unit 115 of the determination result.

The command generation unit 114 can transmit a drive command for driving the blower 150 and a stop command for stopping the driving blower 150 to the blower 150. The command generation unit 114 generates a drive command on the condition that "the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation", and is generated via the transmission unit 116. The drive command is transmitted to the blower 150.

The communication IF unit 115 notifies the operation device 140 of information based on the determination result received from the determination unit 113. For example, the communication IF unit 115 indicates that the blower 150 is in the driving state (during operation) when the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation. Notify to. In this case, the operating device 140 notifies the display unit 141 that the blower 150 is being driven (operating).

The communication IF unit 115 receives a signal from the operation device 140 based on the operation of the operation unit 142 of the operation device 140. The communication IF unit 115 notifies the command generation unit 114 of the signal.

When the blower 150 is stopped, the command generation unit 114 generates a drive command for driving the blower 150, and transmits the drive command to the blower 150 via the transmission unit 116. As a result, the blower 150 starts driving. Further, when the blower 150 is in the drive state, the command generation unit 114 generates a stop command for stopping the drive, and transmits the stop command to the blower 150 via the transmission unit 116. As a result, the drive of the blower 150 is stopped.

<E. Control structure>
FIG. 4 is a flow chart for explaining the processing flow of the controller 110.

With reference to FIG. 4, in step S1, the controller 110 acquires temperature information from the temperature sensor 120 installed in the perimeter zone 941. In step S2, the controller 110 acquires temperature information from the temperature sensor 130 installed in the interior zone 942. Specifically, the controller 110 periodically acquires these temperature information. The order of steps S1 and S2 may be reversed.

In step S3, in the controller 110, the air conditioner 501 for the perimeter zone 941 is in heating operation and the air conditioner 601 for the interior zone 942 is cooling based on the temperature information acquired from the temperature sensors 120 and 130. Determine if you are driving.

When a positive judgment is made in step S3 (YES in step S3), the controller 110 determines whether or not the blower 150 is in the driving state in step S4.

If a positive judgment is made in step S4 (YES in step S4), the controller 110 advances the process to step S1. If a negative determination is made in step S4 (NO in step S4), the controller 110 drives the blower 150 by transmitting a drive command to the blower 150 in step S5.

If a negative determination is made in step S3 (NO in step S3), the controller 110 determines in step S6 whether or not the blower 150 is in the driving state.

If a positive judgment is made in step S6 (YES in step S6), the controller 110 stops the blower 150 by transmitting a stop command to the blower 150 in step S7. If a negative determination is made in step S6 (NO in step S6), the controller 110 advances the process to step S1.

<F. Hardware configuration>
FIG. 5 is a diagram showing a typical example of the hardware configuration of the controller 110.

With reference to FIG. 5, the controller 110 is generated by executing the program by the processor 11 that executes the program, the ROM (Read Only Memory) 12 that stores the data non-volatilely, and the processor 11 as the main components. It includes a RAM (Random Access Memory) 13 that volatilely stores data or data input via an input device, a flash memory 14 that stores data non-volatilely, a communication IF 15, and a clock 16.

Each component is connected to each other by a data bus. In this example, the communication IF 15 is an interface for communicating with various other devices.

The processing in the controller 110 is realized by the software executed by each hardware and the processor 11. Such software may be stored in the flash memory 14 in advance. In addition, the software may be stored in other storage media and distributed as a program product. Alternatively, the software may be provided as a downloadable program product by an information provider connected to the so-called Internet. Such software is read from the storage medium by a reading device, or downloaded via a communication IF 15 or the like, and then temporarily stored in the flash memory 14. The software is read from the flash memory 14 by the processor 11 and stored in the RAM 13 in the form of an executable program. The processor 11 executes the program.

Each component constituting the controller 110 shown in the figure is a general one. Therefore, it can be said that an essential part of the present disclosure is RAM 13, flash memory 14, software stored in a storage medium, or software that can be downloaded via a network. Since the operation of each hardware of the controller 110 is well known, detailed description thereof will not be repeated.

The controller 110 is communicably connected to the temperature sensor 120, the temperature sensor 130, the operating device 140, the blower 150, and the blower 350. As described above, the air conditioning system 1A differs from the air conditioning system 1 in that the blower 350 is provided.

The underfloor 980 in the interior zone 942 is provided with a suction port 410, a duct 420, and an outlet 430. The suction port 410 is provided on the window 902 side of the air outlet 430. The underfloor 980 is a space formed by providing the floor surface 970.

The blower 350 is installed under the floor 980. In this example, the blower 350 is installed in the space below the interior zone 942 in the underfloor 980.

The blower 350 sucks in air from the suction port 410 and blows out air from the outlet 430. Specifically, the air sucked from the suction port 410 flows through the duct 420, and then blows out from the outlet 430 toward the interior zone 942.

The suction port 410 is provided on the floor surface 970 near the perimeter zone 941 in the interior zone 942. Specifically, the suction port 410 is provided near the boundary between the perimeter zone 941 and the interior zone 942. However, the position of the suction port 410 is not limited to this. For example, the suction port 410 may be provided on the floor surface 970 of the perimeter zone 941 near the interior zone 942.

The controller 110 drives the blower 150 and the blower 350 on condition that the air conditioner 501 is in the heating operation and the air conditioner 601 for the interior zone is in the cooling operation. Specifically, the controller 110 sends a drive command for driving the blower 150 to the blower 150, and also sends a drive command for driving the blower 350 to the blower 350.

In the case of this modification, the air flow generated by the blower 350 is generated together with the air flow described with reference to FIG. In the following, the flow generated by the blower 350 will be mainly described. More specifically, the air flow in the interior zone 942 will be described.

The air (that is, cold air) blown out from the air outlet 630 of the air conditioner 601 diffuses as described above. After that, the diffused cold air proceeds in the direction of arrow 62 as a whole.

Since the blower 350 is driven, cold air is subsequently sucked from the suction port 410 (see arrow 64). The sucked cold air is blown out from the outlet 430 toward the interior zone 942 by the blower 350 (see arrow 65).

The air outlet 430 is provided on the central side of the room 940 (the side opposite to the window 902, the back side). Therefore, the cold air blown out from the outlet 430 is blown out toward the center of the room 940. In the case of this example, cold air is blown from the floor surface 970 near the lower part of the air outlet 630 of the air conditioner 601 toward the interior zone 942.

With the above configuration, the air conditioning system 1A exhibits the following actions and effects in addition to the above-mentioned actions and effects of the air conditioning system 1.

By driving the blower 350, the circulation of cold air in the interior zone 942 is promoted. Therefore, the interior zone 942 can be cooled uniformly as compared with the case where the blower 350 is not driven.

Further, since the cold air is sucked from the suction port 410 provided on the floor surface 970 of the interior zone 942, it is possible to prevent the cold air from flowing into the perimeter zone 941. Therefore, the air conditioning system 1 can further increase the heating efficiency and the cooling efficiency at the same time. Therefore, according to the air conditioning system 1A, the mixing loss of heating and cooling can be further reduced as compared with the air conditioning system 1.

(H2. Second modification)
FIG. 7 is a diagram showing a configuration in which a partition plate (hanging wall) is provided on the ceiling 950 of the room 940.

With reference to FIG. 7, the partition plate 1070 is attached to the ceiling 950 in a hanging state. The partition plate 1070 is provided at the boundary between the perimeter zone 941 and the interior zone 942. The length of the partition plate 1070 in the vertical direction (Z-axis direction) should be long. However, it is better not to be too long from the viewpoint of improving the appearance and reducing the feeling of oppression.

FIG. 8 is a cross-sectional view taken along the line VIII-VIII of FIG.
With reference to FIG. 8, the partition plate 1070 is installed so as to be parallel to the window 902. The partition plate 1070 is arranged along the illustrated Y-axis direction.

Also in this modification, the controller 110 drives the blower 150 on the condition that the air conditioner 501 is in the heating operation and the air conditioner 601 for the interior zone is in the cooling operation.

In the case of the modified example of this example, since the partition plate 1070 is installed, the warm air near the ceiling 950 of the perimeter zone 941 is reduced from flowing into the interior zone 942 as compared with the case where the partition plate 1070 is not installed. can. Further, since the partition plate 1070 is installed in the vicinity of the suction port 210, the warm air temporarily retained in the partition plate 1070 can be efficiently sucked from the suction port 210.

Therefore, in this modification, the circulation of warm air in the perimeter zone 941 can be further promoted as compared with the configuration without the partition plate 1070 (for example, the configuration of FIG. 1). Therefore, the perimeter zone 941 can be heated more uniformly as compared with the case where the partition plate 1070 is not installed.

From the above, it is possible to improve the heating efficiency and the cooling efficiency as compared with the case where the partition plate 1070 is not installed. Therefore, according to this modification, the mixing loss of heating and cooling can be further reduced.

(H3. Third modification)
FIG. 9 is a diagram for explaining an air conditioning system 1B which is a modification of the air conditioning system 1. Also in FIG. 9, it is assumed that the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation.

With reference to FIG. 9, the air conditioning system 1B includes a controller 110, a temperature sensor 120, a temperature sensor 130, an operating device 140, a blower 150, a blower 1091, and a blower 1092. The controller 110 is communicably connected to the temperature sensor 120, the temperature sensor 130, the operating device 140, the blower 150, the blower 1091, and the blower 1092. As described above, the air conditioning system 1B differs from the air conditioning system 1 in that the blower 1091 and the blower 1092 are provided.

Blowers 1091 and 1092 are attached to the ceiling 950 (ceiling surface on the indoor 940 side). In this example, the blower 1092, the suction port 210, the blower 1091, and the suction port 610 are arranged in this order from the window 902 side.

In this example, the blower 1092 is installed in the perimeter zone 941. The blower 1091 is installed at the boundary between the perimeter zone 941 and the interior zone 942. The blower 1091 may be installed near the perimeter zone 941 in the interior zone 942.

In this modification, the controller 110 controls the drive of the blower 150, the blower 1091, and the blower 1092.

FIG. 10 is a cross-sectional view taken along the line XX of FIG.
With reference to FIG. 10, the blower 1091 is located on the positive side of the Y-axis (upper side of the figure) and the positive side of the X-axis (right side of the figure, the central portion of the room 940) with respect to the suction port 210. It is installed on the side). The blower 1092 is installed on the negative direction side of the Y axis (lower side in the figure) and the negative direction side of the X axis (left side in the figure, window 902 side) with respect to the suction port 210.

The blower 1091 sends the air in the area 948 toward the suction port 210. Specifically, the blower 1091 sends the air on the ceiling 950 side of the area 948 toward the suction port 210. The blower 1092 sends the air in the area 949 toward the suction port 210. Specifically, the blower 1092 sends the air on the ceiling 950 side of the area 949 toward the suction port 210. In this way, the blower 1091 guides the air on the ceiling 950 side of the room 940 toward the suction port 210.

Area 948 is about the same distance from the outlet 530 of the air conditioner 501 and the outlet 630 of the air conditioner 601. Therefore, in area 948, warm air and cold air are mixed. Specifically, since the warm air is lighter than the cold air, the air on the ceiling 950 side becomes warm air and the air on the floor surface 970 side becomes cold air in the area 948.

Therefore, the blower 1091 sends the warm air on the ceiling 950 side in the area 948 toward the suction port 210. Similarly, the blower 1092 sends the warm air on the ceiling 950 side in the area 949 toward the suction port 210. Therefore, the air conditioning system 1B can improve the heating efficiency and the cooling efficiency as compared with the air conditioning system 1. Therefore, according to this modification, the mixing loss of heating and cooling can be further reduced.

(H4. Fourth modification)
In the above, the controller 110 determines that "the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation" based on the outputs from the temperature sensors 120 and 130. However, the controller 110 may determine that "the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation" by another method.

For example, even if the controller 110 determines that "the air conditioner 501 is in the heating operation and the air conditioner 601 is in the cooling operation" by communicating with the air conditioner 501 and the air conditioner 601. good.

Specifically, the controller 110 determines whether or not the air conditioner 501 is in heating operation by acquiring information (operation information) indicating the operation mode of the air conditioner 501 from the air conditioner 501. It is also good. Similarly, the controller 110 may determine whether or not the air conditioner 601 is in cooling operation by acquiring information indicating the operation mode of the air conditioner 601 from the air conditioner 601.

When the air conditioners 501 and 601 are central air conditioners instead of individual air conditioners, the controller 110 indicates the operation mode of the air conditioners 501 and 601 from the management device that manages the operation of the air conditioners 501 and 601. Information may be obtained.

In the above, the first to fourth modification examples have been described, but it is also possible to appropriately combine each of these modification examples.
