[0010] Hereinafter, embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In the embodiments and modified examples, identical or equivalent components and members are designated by the same reference numerals, and redundant explanations will be omitted where appropriate. Furthermore, the dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. Furthermore, some members that are not important for explaining the embodiments will be omitted from the drawings.

[0011] 1 shows a schematic configuration of a control system 1 according to an embodiment. The control system 1 is installed in a building 100 and controls the ventilation and air conditioning of the interior of the building 100. The control system 1 can also be called an air conditioning system. The control system 1 includes a first air conditioning unit 10a, a second air conditioning unit 10b, a first operating device 12a, a second operating device 12b, a control device 14, an air intake 20, an intake fan 22, an exhaust outlet 24, an air outlet 26, a first duct 28, a second duct 30, a first air duct 32, a second air duct 34, and an air duct switching unit 36.

[0012] A first space 102a and a second space 102b, such as an interior space, are provided in the building 100. The first space 102a and the second space 102b are separated, for example, by a wall. An example of the first space is a room (work area) in a company, and an example of the second space is a conference room in a company.

[0013] The air intake 20 is installed on the ceiling of the first space 102a or the like. The air intake 20 is an intake port for taking in air from the first space 102a. The air intake 20 can also be said to be an indoor exhaust port.

[0014] The exhaust port 24 is installed on the outer wall 104 of the building 100. The exhaust port 24 is an outlet for discharging the air in the first space 102a to the outdoors as exhaust air. The exhaust port 24 can also be called an outdoor exhaust port.

[0015] The intake port 20 and the exhaust port 24 are in communication with each other via a second duct 30. The second duct 30 is disposed in the ceiling of the building 100, for example.

[0016] The intake fan 22 is disposed downstream of the intake port 20 in the second duct 30 and takes in air through the intake port 20. The intake fan 22 is a centrifugal impeller such as a sirocco fan. An electric motor (not shown) rotatably supports the intake fan 22. The intake fan 22 and the electric motor constitute a blower that sends air into the second duct 30.

[0017] A second air passage 34 is formed in the second duct 30. The second air passage 34 guides the air in the first space 102a taken in from the air inlet 20 by the air intake fan 22 through the air outlet 24 to the outdoors.

[0018] The air outlet 26 is installed on the ceiling of the second space 102b, etc. The air outlet 26 is an outlet for blowing air into the second space 102b.

[0019] The air inlet 20 and the air outlet 26 are in communication with each other via a part of the second duct 30 and the first duct 28. The first duct 28 is connected to a midpoint of the second duct 30. The first duct 28 is disposed, for example, above the ceiling of the building 100.

[0020] A first air passage 32 is formed within first duct 28. First air passage 32 is connected to second air passage 34 at connection portion 40. First air passage 32 guides air from first space 102a, which is taken in from inlet 20 by intake fan 22, to outlet 26.

[0021] The air path switching unit 36 ​​has, for example, a damper, and is disposed downstream of the intake fan 22 within the second duct 30. The damper is a partition plate for opening and closing the air path, and is driven by an actuator (not shown) in accordance with the control of the control device 14. The air path switching unit 36 ​​is disposed at a connection portion 40 between the first air path 32 and the second air path 34. The air path switching unit 36 ​​is operable in a first state in which the first air path 32 is open and the second air path 34 is closed, or in a second state in which the first air path 32 is closed and the second air path 34 is open. In FIG. 1 , the air path switching unit 36 ​​in the first state is schematically indicated by a dashed line, and the air path switching unit 36 ​​in the second state is schematically indicated by a solid line.

[0022] The air-path switching unit 36 ​​switches between blowing the air taken in by the intake fan 22 from the first space 102a into the second space 102b via the first air path 32 and blowing it outdoors via the second air path 34. In the first state, the air-path switching unit 36 ​​blows the air from the first space 102a into the second space 102b via the first air path 32, and in the second state, blows the air from the first space 102a outdoors via the second air path 34. In FIG. 1 , the air flow A10 upstream of the air-path switching unit 36 ​​is schematically indicated by a solid arrow. The air flow A1 downstream of the air-path switching unit 36 ​​when the air-path switching unit 36 ​​is in the first state is schematically indicated by a dashed arrow. The air flow A2 downstream of the air-path switching unit 36 ​​when the air-path switching unit 36 ​​is in the second state is schematically indicated by a solid arrow.

[0023] The human detection unit 16 detects a person entering the second space 102b. When the human detection unit 16 detects a person entering the second space 102b, it outputs a signal indicating that a person has been detected to the control device 14. The human detection unit 16 is, for example, a human sensor, a camera, an ultrasonic sensor, or a contact sensor that detects contact between a door and a wall. Various known technologies can be used as the human detection unit 16.

[0024] The human detection unit 16 may be placed anywhere as long as it can detect a person entering the second space 102b. The human detection unit 16 may be placed on the ceiling or side wall of the second space 102b, at the air outlet 26, or in the same housing as the second air conditioning unit 10b.

[0025] The first air conditioning apparatus 10a and the first operating device 12a are installed in the first space 102a. The second air conditioning apparatus 10b and the second operating device 12b are installed in the second space 102b. Hereinafter, the first air conditioning apparatus 10a and the second air conditioning apparatus 10b will be collectively referred to as air conditioning apparatuses 10 as appropriate. The first operating device 12a and the second operating device 12b will be collectively referred to as operating devices 12 as appropriate.

[0026] The air conditioning device 10 is an air conditioner. The air conditioning device 10 can be installed, for example, on the ceiling or side wall inside the building 100.

[0027] The first air conditioner 10a performs air conditioning control on the air drawn in from the first space 102a and sends the temperature-controlled air to the first space 102a. In other words, the first air conditioner 10a conditions the air in the first space 102a.

[0028] The second air conditioner 10b performs air conditioning control on the air drawn in from the second space 102b and sends the temperature-controlled air to the second space 102b. In other words, the second air conditioner 10b conditions the air in the second space 102b.

[0029] The operation device 12 is, for example, a remote control. The operation device 12 has a user interface that can be operated by a user, and accepts operation inputs from the user, such as an operation start instruction, an operation stop instruction, a set temperature, etc. The set temperature is a target temperature for the air conditioner 10.

[0030] The first operating device 12a is equipped with a first temperature sensor 18a, which detects the temperature of the air in the first space 102a. The first operating device 12a is communicatively connected to the first air conditioning apparatus 10a. The first operating device 12a transmits to the first air conditioning apparatus 10a information on an operation start instruction, an operation stop instruction, a first space target temperature which is the target temperature for the first air conditioning apparatus 10a, and a first space temperature which is the detected temperature of the first space 102a.

[0031] The first air conditioner 10a is capable of performing heating operation or cooling operation based on the information received from the first operating device 12a so that the first space temperature approaches the first space target temperature.

[0032] The second operating device 12b is equipped with a second temperature sensor 18b, which detects the temperature of the air in the second space 102b. The second operating device 12b is communicatively connected to the second air conditioning apparatus 10b. The second operating device 12b transmits to the second air conditioning apparatus 10b information on an operation start instruction, an operation stop instruction, a second space target temperature which is the target temperature for the second air conditioning apparatus 10b, and a second space temperature which is the detected temperature of the second space 102b.

[0033] The second air conditioning device 10b can perform heating or cooling operation so that the second space temperature approaches the second space target temperature based on the information received from the second operating device 12b. The first air conditioning device 10a and the second air conditioning device 10b can operate independently of each other.

[0034] The first temperature sensor 18a may be provided at any location within the first space 102a as long as it can detect the temperature in the first space 102a. The first temperature sensor 18a may be provided, for example, in the first air conditioning device 10a, in the air inlet 20, or on the ceiling or side wall of the first space 102a. The second temperature sensor 18b may be provided at any location within the second space 102b as long as it can detect the temperature in the second space 102b. The second temperature sensor 18b may be provided in the second air conditioning device 10b, or on the ceiling or side wall of the second space 102b.

[0035] The control device 14 is communicatively connected to each of the first air conditioning device 10a, the second air conditioning device 10b, and the air-channel switching unit 36. The control device 14 controls the air-channel switching unit 36 ​​based on information transmitted from the first air conditioning device 10a and the second air conditioning device 10b.

[0036] The control device 14 may be located anywhere. For example, the control device 14 may be configured as a system controller or a central control device installed in the building 100. The control device 14 may be configured together with the first operating device 12a or the second operating device 12b as an integrated control panel installed in the building 100. The control device 14, the first air conditioning device 10a, the second air conditioning device 10b, and the air channel switching unit 36 ​​may communicate with each other via wired or wireless communication. The control device 14, the first air conditioning device 10a, the second air conditioning device 10b, and the air channel switching unit 36 ​​may communicate with each other via a network (not shown), or may communicate directly without using a network.

[0037] Furthermore, the control device 14 may be disposed in the same housing as the first air conditioning device 10a, or may be configured integrally with a control unit (not shown) of the first air conditioning device 10a. Alternatively, the control device 14 may be disposed in the same housing as the second air conditioning device 10b, or may be configured integrally with a control unit (not shown) of the second air conditioning device 10b. The control device 14 may be disposed in the same housing as the intake fan 22, or may be configured integrally with the intake fan 22. The control device 14 may be disposed in the same housing as the air path switching unit 36, or may be configured integrally with the air path switching unit 36.

[0038] The control device 14 may also be a server. In this case, the first air conditioning device 10a, the second air conditioning device 10b, and the air channel switching unit 36 ​​each have wireless communication capabilities and are communicatively connected to the control device 14 via a network such as the Internet via a wireless station (not shown) that is a base station. The first air conditioning device 10a, the second air conditioning device 10b, and the air channel switching unit 36 ​​may also each be communicatively connected to the control device 14 via a network using wired communication.

[0039] Figure 2 is a schematic functional block diagram of the control device 14 and its peripheral configuration in Figure 1. The control device 14 includes a first space target temperature acquisition unit 50, a first space temperature acquisition unit 52, a second space target temperature acquisition unit 54, a second space temperature acquisition unit 56, a determination unit 58, and a control unit 60.

[0040] The configuration of the control device 14 can be realized in hardware terms by the CPU, memory, and other LSI of any computer, and in software terms by programs loaded into memory, but here the functional blocks realized by the cooperation of these are depicted. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms using only hardware, only software, or a combination of both.

[0041] Each functional block of the control device 14 may be distributed and arranged in at least two of the first air conditioner 10a, the second air conditioner 10b, the air path switching unit 36, and the server.

[0042] The first space target temperature acquisition unit 50 acquires the first space target temperature from the first air conditioning device 10a and supplies the acquired information to the control unit 60. Note that the first space target temperature acquisition unit 50 may also acquire the first space target temperature from the first operating device 12a.

[0043] The first space temperature acquisition unit 52 acquires the first space temperature from the first air conditioning device 10a and supplies the acquired information to the control unit 60. The first space temperature acquisition unit 52 may acquire the first space temperature directly from the first temperature sensor 18a.

[0044] The second space target temperature acquisition unit 54 acquires the second space target temperature from the second air conditioning device 10b and supplies the acquired information to the control unit 60. Note that the second space target temperature acquisition unit 54 may also acquire the second space target temperature from the second operating device 12b.

[0045] The second space temperature acquisition unit 56 acquires the second space temperature from the second air conditioning device 10b and supplies the acquired information to the control unit 60. The second space temperature acquisition unit 56 may acquire the second space temperature directly from the second temperature sensor 18b.

[0046] The determination unit 58 determines whether a person has entered the second space 102b and supplies the determination result to the control unit 60. When the person detection unit 16 detects a person entering the second space 102b, the determination unit 58 determines that a person has entered the second space 102b. When the person detection unit 16 does not detect a person entering the second space 102b, the determination unit 58 determines that no person has entered the second space 102b.

[0047] The second air conditioning apparatus 10b may transmit operation start information to the control apparatus 14 when starting heating or cooling operation in response to an operation input to the second operating device 12b. The determination unit 58 may determine that a person has entered the second space 102b when it acquires operation start information for the second air conditioning apparatus 10b from the second air conditioning apparatus 10b. The determination unit 58 may determine that a person has not entered the second space 102b when it has not acquired operation start information for the second air conditioning apparatus 10b. The second operating device 12b may transmit operation start information to the control apparatus 14 when it starts heating or cooling operation in response to an operation input to the second operating device 12b. In this configuration example, the human detection unit 16 may not be provided. Not providing the human detection unit 16 improves the installability of the control system 1 and makes installation easier. Various other known technologies may be used to determine whether a person has entered the second space 102b.

[0048] The control unit 60 controls the air path switching unit 36 ​​based on the operating state of the first air conditioning device 10a, the first space target temperature, the first space temperature, the second space target temperature, the second space temperature, and the judgment result of the judgment unit 58.

[0049] When the determination unit 58 determines that no one is present in the second space 102b, the control unit 60 performs outdoor blow-out control to control the air path switching unit 36 ​​so that the air in the first space 102a taken in by the intake fan 22 is blown out to the outdoors via the second air path 34. The outdoor blow-out control ventilates the first space 102a.

[0050] Below, the control that is performed when the judgment unit 58 determines that a person has entered the second space 102b will be explained in the following order: (1) control during heating operation of the first air conditioning device 10a, (2) control during cooling operation of the first air conditioning device 10a, and (3) control when the first air conditioning device 10a is stopped.

[0051] (1) Control of the first air conditioner 10a during heating operation When the judgment unit 58 determines that a person has entered the second space 102b, if the first air conditioning unit 10a is in heating operation and the difference between the first space target temperature and the first space temperature is less than a predetermined value, the control unit 60 performs second space blowing control, which controls the air path switching unit 36 ​​to blow the air from the first space 102a taken in by the intake fan 22 into the second space 102b via the first air path 32.

[0052] The predetermined value may be, for example, several degrees Celsius or about 2 degrees Celsius. The predetermined value can be determined appropriately through experiments. The predetermined value may be set in response to an operation input by the user to the first operating device 12a or the second operating device 12b.

[0053] When the judgment unit 58 determines that a person has entered the second space 102b, if the first air conditioning device 10a is in heating operation and the difference between the first space target temperature and the first space temperature is greater than a predetermined value, the control unit 60 does not perform second space blowing control, but instead performs, for example, outdoor blowing control.

[0054] Therefore, even if it is determined that a person has entered the second space 102b, the control system 1 continues normal ventilation until the first space temperature approaches the first space target temperature. After the first space temperature approaches the first space target temperature, the warmed air from the first space 102a can be blown into the second space 102b. This allows the second space 102b to be heated efficiently. Because the second space 102b can be heated using the air from the first space 102a, when the second air conditioning device 10b starts heating operation after a person enters the second space 102b, the air conditioning load required for the second space temperature to reach the second space target temperature can be reduced, and the time required for the second space temperature to reach the second space target temperature can be shortened. This allows the comfort of the user entering the second space 102b to be improved, for example, in a situation where the building 100 is a company building or the like and a person moves from the first space 102a, which is a living room, to the second space 102b, which is a conference room.

[0055] In addition, since the air in the first space 102a can be blown into the second space 102b only for the necessary period, only the necessary amount of air from the first space 102a, which may have a high concentration of CO2 and the like, can be sent to the second space 102b.

[0056] When the difference between the first space target temperature and the first space temperature is greater than a predetermined value and outdoor discharge control is performed, the control unit 60 may reduce the airflow rate of the intake fan 22 or may stop the intake fan 22 for a certain period of time. This allows heating of the first space 102a to take priority over ventilation, making it easier for the first space 102a to warm up.

[0057] The control unit 60 may perform the second space air-out control only when the second space temperature is lower than the first space temperature when the difference between the first space target temperature and the first space temperature is equal to or smaller than a predetermined value. The control unit 60 may perform the outdoor air-out control only when the second space temperature is equal to or higher than the first space temperature when the difference between the first space target temperature and the first space temperature is equal to or smaller than a predetermined value.

[0058] As a result, for example, if a meeting or the like has been held in the second space 102b until just before the event and the second space 102b is already warm, and someone enters the second space 102b, the second space air outlet control will not be executed. Also, for example, even if the second air conditioning device 10b is not in heating operation after someone enters the cold second space 102b, if the second space temperature becomes equal to the first space temperature due to continued second space air outlet control, the second space air outlet control will be stopped and switched to outdoor air outlet control. This allows air from the first space 102a to be blown into the second space 102b for a more appropriate period of time.

[0059] The control unit 60 may terminate the second space air-conditioning control and, for example, start outdoor air-conditioning control if the second air-conditioning device 10b is in heating operation after performing the second space air-conditioning control and the difference between the second space target temperature and the second space temperature is equal to or less than a predetermined value. The control unit 60 may continue the second space air-conditioning control if the second air-conditioning device 10b is in heating operation after performing the second space air-conditioning control and the difference between the second space target temperature and the second space temperature is not equal to or less than a predetermined value. The control unit 60 may determine that the difference between the second space target temperature and the second space temperature is not equal to or less than a predetermined value if the second air-conditioning device 10b is stopped after performing the second space air-conditioning control. This control also allows air from the first space 102a to be blown to the second space 102b for a more appropriate period of time.

[0060] (2) Control of the first air conditioner 10a during cooling operation When the judgment unit 58 determines that a person has entered the second space 102b, and the first air conditioning device 10a is in cooling operation, the control unit 60 performs second space blowing control if the difference between the first space temperature and the first space target temperature is less than a predetermined value.

[0061] When the judgment unit 58 determines that a person has entered the second space 102b, if the first air conditioning device 10a is in cooling operation and the difference between the first space temperature and the first space target temperature is greater than a predetermined value, the control unit 60 does not perform second space blowing control, but instead performs, for example, outdoor blowing control.

[0062] Therefore, even if it is determined that a person has entered the second space 102b, the control system 1 continues normal ventilation until the first space temperature approaches the first space target temperature, and only after the first space temperature approaches the first space target temperature can the cooled air from the first space 102a be blown into the second space 102b. This allows the second space 102b to be cooled efficiently. Because the second space 102b can be cooled using the air from the first space 102a, when the second air conditioning device 10b starts cooling operation after a person has entered the second space 102b, the air conditioning load until the second space temperature reaches the second space target temperature can be reduced, and the time until the second space temperature reaches the second space target temperature can be shortened. This allows the comfort of the user who has entered the second space 102b to be improved.

[0063] In addition, since the air in the first space 102a can be blown into the second space 102b only for the necessary period, only the necessary amount of air from the first space 102a, which may have a high concentration of CO2 and the like, can be sent to the second space 102b.

[0064] When the difference between the first space temperature and the first space target temperature is greater than a predetermined value and outdoor discharge control is performed, the control unit 60 may reduce the airflow rate of the intake fan 22 or may stop the intake fan 22 for a certain period of time. This allows cooling of the first space 102a to take priority over ventilation, making it easier for the first space 102a to cool.

[0065] The control unit 60 may perform the second space air-out control only when the second space temperature is higher than the first space temperature when the difference between the first space temperature and the first space target temperature is equal to or less than a predetermined value. The control unit 60 may perform the outdoor air-out control only when the second space temperature is equal to or less than the first space temperature when the difference between the first space temperature and the first space target temperature is equal to or less than a predetermined value.

[0066] As a result, for example, if a meeting or the like has been held in the second space 102b until just before the event and the second space 102b is already cooled, and someone enters the second space 102b, the second space air outlet control will not be executed. Also, for example, even if the second air conditioning device 10b is not in cooling operation after someone enters the hot second space 102b, if the second space temperature becomes equal to the first space temperature due to continued second space air outlet control, the second space air outlet control will be stopped and switched to outdoor air outlet control. This allows air from the first space 102a to be blown into the second space 102b for a more appropriate period of time.

[0067] After performing the second space air-out control, if the second air conditioning device 10b is in cooling operation and the difference between the second space temperature and the second space target temperature is equal to or less than a predetermined value, the control unit 60 may terminate the second space air-out control and, for example, start outdoor air-out control. After performing the second space air-out control, if the second air conditioning device 10b is in cooling operation and the difference between the second space temperature and the second space target temperature is not equal to or less than a predetermined value, the control unit 60 may continue the second space air-out control. This control also makes it possible to blow air from the first space 102a to the second space 102b for a more appropriate period of time.

[0068] (3) Control when the first air conditioning unit 10a is stopped The state when the first air conditioning device 10a is stopped refers to a state in which the power to the first air conditioning device 10a is turned off and the first air conditioning device 10a is not performing either heating or cooling operation. Even if the determination unit 58 determines that a person has entered the second space 102b, the control unit 60 continues, for example, outdoor air outlet control as long as the first air conditioning device 10a is stopped.

[0069] Fig. 3 is a flowchart showing the control procedure of the control system 1 in Fig. 1. The control unit 60 executes outdoor air discharge control (S10), and the determination unit 58 determines whether a person has entered the second space 102b (S12). If a person has not entered the second space 102b (N in S12), the process returns to S10.

[0070] If a person has entered the second space 102b (Y in S12), the first air conditioning device 10a is in heating operation (Y in S14), the difference "T1t - T1" between the first space target temperature T1t and the first space temperature T1 is equal to or less than a predetermined value Tp (Y in S16), and the second space temperature T2 is lower than the first space temperature T1 (Y in S18), the control unit 60 executes second space air outlet control (S20). If the difference "T2t - T2" between the second space target temperature T2t and the second space temperature T2 is not equal to or less than the predetermined value Tp (N in S22), the process returns to S18. If "T2t - T2" is equal to or less than the predetermined value Tp (Y in S22), the control unit 60 executes outdoor air outlet control (S34), and the process ends.

[0071] If "T1t-T1" is not equal to or less than the predetermined value Tp in S16 (N in S16), the process returns to S 16. If the second space temperature T2 is not lower than the first space temperature T1 in S18 (N in S18), the process proceeds to S34.

[0072] If the first air conditioning apparatus 10a is not in heating operation in S14 (N in S14), the first air conditioning apparatus 10a is in cooling operation (Y in S24), the difference "T1 - T1t" between the first space temperature T1 and the first space target temperature T1t is equal to or less than the predetermined value Tp (Y in S26), and the second space temperature T2 is higher than the first space temperature T1 (Y in S28), the control unit 60 executes second space air outlet control (S30). If the difference "T2 - T2t" between the second space temperature T2 and the second space target temperature T2t is not equal to or less than the predetermined value Tp (N in S32), the process returns to S28. If "T2 - T2t" is equal to or less than the predetermined value Tp (Y in S32), the process proceeds to S34.

[0073] If "T1-T1t" is not equal to or less than the predetermined value Tp in S26 (N in S26), the process returns to S26. If the second space temperature T2 is not higher than the first space temperature T1 in S28 (N in S28), the process proceeds to S34.

[0074] If the first air conditioner 10a is not in cooling operation in S24 (N in S24), the process ends.

[0075] According to the embodiment, air-channel switching unit 36 ​​is controlled based on the first space target temperature, the first space temperature, and the determination result of determination unit 58, so it is possible to switch between exhausting the air in first space 102a to the outdoors or blowing it into second space 102b depending on the relationship between the first space target temperature and the first space temperature and whether or not a person has entered second space 102b. Therefore, when a person has entered second space 102b, temperature-adjusted air in first space 102a is blown into second space 102b, thereby improving the comfort of the person who has entered second space 102b.

[0076] Furthermore, even if the second air conditioning device 10b starts operating after someone has entered the second space 102b, the temperature of the second space 102b can be adjusted faster by blowing the temperature-adjusted air from the first space 102a into the second space 102b, which makes it easier for the user to feel more comfortable.

[0077] In the above explanation, an example has been described in which the second air conditioning device 10b is provided in the second space 102b, but as will be explained below, the second air conditioning device 10b does not have to be provided in the second space 102b. Below, the differences from the previously described configuration in which the second air conditioning device 10b is provided will be mainly explained.

[0078] Although not shown in the drawings, the control device 14 does not need to have the second space target temperature acquisition unit 54. The second space temperature acquisition unit 56 directly acquires the second space temperature from the second temperature sensor 18b provided at an arbitrary location within the second space 102b.

[0079] Fig. 4 is a flowchart showing the control procedure of the control system 1 when the second air conditioning device 10b is not provided in the second space 102b. The flowchart in Fig. 4 differs from the flowchart in Fig. 3 in that the processes of S22 and S32 are not performed, the process returns to S18 after S20, and the process returns to S28 after S30.

[0080] This configuration also improves the comfort of the user who enters the second space 102b. Furthermore, the determination processes of S16, S18, S26, and S28 can cause the air in the first space 102a to be blown into the second space 102b for an appropriate period of time.
