Fig. 2 is a plan view that typically shows the space 100 in which the air conditioning system of the embodiment 1 is used. Fig. 3 is a perspective view of an indoor unit 1 of the air conditioning apparatus of the embodiment 1.

The air conditioning system according to this embodiment suppresses a decrease in comfort and productivity of users 50 who are present in a space 100 as shown in FIG. 1, or improves the comfort and productivity of users 50. Space 100 is, for example, the interior space of a room.

As shown in FIG. 1, as an example, there are multiple users 50 in the space 100. The users 50 are, for example, seated or standing. As an example, a seated table 101 and chairs surrounding the table 101 are provided in the space 100. In FIG. 1, as an example, users 50a and 50b are shown working in a seated position. Note that the table 101 may be provided with an acrylic panel, for example, to prevent droplets from spreading between the seated users 50.

The air conditioning system according to this embodiment includes an air conditioning device. The air conditioning device is a device that conditions the air in the space 100. The air conditioning device is capable of performing air conditioning operations including, for example, a cooling operation that blows out cool air, a heating operation that blows out warm air, and a fan operation that blows out air at room temperature. In addition, the air conditioning device according to this embodiment is capable of performing a productivity improvement operation. A productivity improvement operation is an operation that is advantageous in improving at least one of the comfort and productivity of the user 50. A detailed explanation of the productivity improvement operation will be given later.

As shown in Figs. 1 and 2, the air conditioning system according to this embodiment includes a first air conditioning device 1a and a second air conditioning device 1b. The first air conditioning device 1a and the second air conditioning device 1b are air conditioning devices configured to vary the air blowing direction, the temperature of the air blown out, and the volume of the air blown out. The second air conditioning device 1b is disposed adjacent to the first air conditioning device 1a. The number of air conditioning devices included in the air conditioning system according to the present disclosure may be one, or three or more.

As shown in FIG. 2, in this embodiment, the first air conditioning unit 1a blows air to area A in the space 100. The second air conditioning unit 1b blows air to area B in the space 100. Areas A and B are adjacent regions. Area A is an example of a first area. Area B is an example of a second area.

The first air conditioning device 1a and the second air conditioning device 1b each include an indoor unit 1. In this disclosure, this indoor unit 1 may also be referred to simply as an "air conditioning device." The indoor unit 1 is installed on the ceiling surface of a room in which a space 100 is formed. Note that the indoor unit 1 of the air conditioning device may be configured to be installed on a floor surface or a wall surface, for example.

The indoor unit 1 is connected to an outdoor unit via piping through which a refrigerant flows. Illustrations of this piping and the outdoor unit are omitted in this disclosure. Also, illustrations of the devices that make up the refrigeration cycle necessary for the air conditioner to perform air conditioning operation, and the blower fan for blowing air into the space 100, etc. are omitted in this disclosure. The devices that make up the refrigeration cycle include, for example, a heat exchanger and a compressor.

As shown in FIG. 3, the indoor unit 1 includes a housing 30. The housing 30 of the indoor unit 1 is formed in a box shape having a substantially rectangular parallelepiped shape. A rectangular or square decorative panel 31 is provided at the bottom of the housing 30 of the indoor unit 1. The indoor unit 1 is installed embedded in the ceiling so that the decorative panel 31 is visible from the ceiling surface.

An intake port 3 is formed at the bottom of the housing 30 of the indoor unit 1. The intake port 3 is an opening for taking in air from the outside into the inside of the housing 30. As an example, the intake port 3 is located in the center of the decorative panel 31, as shown in FIG. 3.

In addition, an air outlet 20 is formed in the lower part of the housing 30 of the indoor unit 1. The air outlet 20 is an opening for discharging air from inside the housing 30 to the outside. In this embodiment, as an example, four air outlets 20 are formed. The four air outlets 20 are arranged around the air inlet 3 as shown in FIG. 3. The four air outlets 20 are provided along each side of the decorative panel 31.

The indoor unit 1 is configured to change the air blowing direction. As an example, the indoor unit 1 is equipped with up-down louvers 2. The up-down louvers 2 are provided at each of the air outlets 20. The up-down louvers 2 are for adjusting the up-down blowing angle of the air blown out from the air outlets 20. In addition, left-right louvers (not shown) are provided inside the up-down louvers 2 for adjusting the left-right blowing angle of the air blown out from the air outlets 20.

The upper and lower louvers 2 are rectangular plate-shaped members. One end of the upper and lower louvers 2 is rotatably attached to the edge of the air outlet 20. The upper and lower louvers 2 rotate around this end as an axis, changing the vertical blowing angle of the air blown out from the air outlet 20. The left and right louvers are composed of multiple rectangular plate-shaped members. These multiple rectangular plate-shaped members are arranged along a direction perpendicular to the longitudinal direction of the air outlet 20. One end of the left and right louvers is rotatably attached to the inner part of the edge of the air outlet 20. The left and right louvers rotate around this end as an axis, changing the horizontal blowing angle of the air blown out from the air outlet 20. By changing the combination of the orientation of the upper and lower louvers 2 and the orientation of the left and right louvers, it is possible to blow air in various directions. The upper and lower louvers 2 and the left and right louvers may be driven independently of each other.

In addition, by orienting the upper and lower louvers 2 in the most upward direction, the air outlets 20 are blocked by the upper and lower louvers 2. The air conditioning device according to this embodiment can stop the blowing of air from some of the multiple air outlets 20 by blocking some of the air outlets 20 with the upper and lower louvers 2.

Inside the housing 30, an air passage is formed that runs from the intake 3 to the exhaust 20. A blower fan (not shown) and the like are installed inside this air passage. The blower fan is for generating an air flow from the intake 3 to the exhaust 20 in the air passage inside the housing 30. When the blower fan operates, air is sucked in through the intake 3 and blown out through the exhaust 20. At this time, the direction in which air is blown out from the exhaust 20 is adjusted by the top and bottom louvers 2 and the left and right louvers arranged on the downwind side of the blower fan. The volume of air blown out from the exhaust 20 can be changed by changing the rotation speed of the blower fan.

Of the multiple air outlets 20 in the indoor unit 1, the air outlet 20 on the left side in FIG. 1 will also be referred to as air outlet 20a. Of the multiple air outlets 20 in the indoor unit 1, the air outlet 20 on the right side in FIG. 1 will also be referred to as air outlet 20b. Also, four upper and lower louvers are shown in FIG. 3. These four upper and lower louvers will also be referred to as upper and lower louvers 2a, 2b, 2c, and 2d, respectively. The upper and lower louvers 2a change the direction in which air is blown out from the air outlet 20a. The upper and lower louvers 2b change the direction in which air is blown out from the air outlet 20b.

The air conditioning system according to this embodiment also includes a vital sensor 41. The vital sensor 41 is a sensor capable of detecting the biometric information of the user 50 in a non-contact manner. The biometric information detected by the vital sensor 41 includes at least one of the heart rate and the pulse wave.

The vital sensor 41, for example, irradiates microwaves or millimeter waves toward the user 50. Displacement of the chest due to the beating of the user's 50's heart causes a Doppler effect, which fluctuates the frequency of the microwaves or millimeter waves irradiated toward the user 50. The vital sensor 41 can detect the heartbeat or pulse wave of each individual user 50 by detecting this frequency fluctuation. Note that the method of detecting biological information by the vital sensor 41 is not limited to this example.

As an example, the vital sensors 41 are installed at each seat of the table 101 where the users 50 sit and work. In the example shown in FIG. 1, the vital sensors 41 are attached to the upper part of the front side of the table 101. The installation position of the vital sensors 41 is not limited to this example. For example, the vital sensors 41 may be installed on the ceiling surface of the room in which the space 100 is formed, or may be attached to the decorative panel 31 of the indoor unit 1, or may be installed in any other position. The vital sensors 41 may be configured to detect the biometric information of the users 50 in the space 100 in a non-contact manner.

The air conditioning system according to this embodiment also includes, as a component thereof, a mobile terminal carried by the user 50. This mobile terminal may be any device capable of acquiring location information. For example, a smartphone corresponds to the mobile terminal. The mobile terminal acquires location information, for example, by using a GPS function, and the mobile terminal periodically transmits the location information. The air conditioning system according to this embodiment is configured to be able to detect the location of each user 50 based on the location information transmitted by the mobile terminal carried by the user 50. Note that the method of detecting the location of the user 50 using the mobile terminal is not limited to using the GPS function, and may be another method, such as a method using the radio wave strength of a wireless communication function or a method using a beacon as the mobile terminal.

The mobile terminal and vital sensor 41 carried by the user 50 may be equipped with a wireless communication function such as BLE (Bluetooth Low Energy) (registered trademark). As an example, when the mobile terminal carried by the user 50 is paired with the vital sensor 41 via the wireless communication function, detection of the biometric information of the user 50 may begin. Furthermore, the biometric information and location information of the user 50 in the space 100 may be matched by pairing the vital sensor 41 with the mobile terminal via the wireless communication function. This allows the air conditioning system to more accurately acquire the biometric information and location information of each user 50.

Figure 4 is a block diagram showing the configuration of a control system of the air conditioning system of the first embodiment. As shown in Figure 4, the air conditioning system of the present embodiment includes an information processing unit 60 and a control unit 63. The information processing unit 60 processes the bioinformation output from the vital sensor 41. The information processing unit 60 also processes the position information transmitted from the mobile terminal carried by the user 50. The information processing unit 60 detects the position of each user 50 in the space 100 based on the position information transmitted from the mobile terminal carried by the user 50. The control unit 63 outputs a control command to the first air conditioning unit 1a and the second air conditioning unit 1b according to the result of the information processing by the information processing unit 60. The information processing unit 60 and the control unit 63 constitute an example of a control means according to the present disclosure.

The information processing unit 60 has, for example, an individual determination unit 61 and a state determination unit 62. The individual determination unit 61 determines which user 50 the biometric information output from the vital sensor 41 belongs to. The state determination unit 62 analyzes the detected biometric information of the user 50.

Each of the first air conditioning unit 1a and the second air conditioning unit 1b is equipped with a left/right louver control unit 65 that controls the drive of the left/right louvers, an up/down louver control unit 67 that controls the drive of the up/down louvers 2, an air volume control unit 66 that controls the air volume by controlling the drive of the blower fan, and a temperature control unit 68 that controls the temperature of the air blown out by controlling the operation of the heat exchanger, etc. The control unit 63 outputs specific control commands to each of the left/right louver control unit 65, the up/down louver control unit 67, the air volume control unit 66, and the temperature control unit 68 according to the processing results by the information processing unit 60.

As described above, the information processing unit 60 and the control unit 63 are an example of a control means according to the present disclosure. This control means controls the air conditioner based on the bioinformation detected by the vital sensor 41 and the location information transmitted by the mobile terminal. Specifically, the control means controls the air conditioner to perform a productivity improvement operation of directing airflow at users in a space.

As described above, the air conditioner is capable of executing a productivity improvement operation. A productivity improvement operation is an operation that improves the productivity of a user 50 by stimulating the user 50 with an airflow. In this embodiment, when executing a productivity improvement operation, the air conditioner blows out room temperature air through fan operation, or blows out cool air through cooling operation. In addition, the air may be blown while changing the direction of the airflow, thereby providing the user 50 with a stimulation such as a sense of fluctuation. Such a productivity improvement operation improves not only the productivity of the user 50 but also the comfort of the user 50 at the same time.

In this embodiment, the indoor unit 1 is capable of blowing air in multiple directions simultaneously. For example, it is possible to deliver airflow to each and every user 50 even within the same area. Furthermore, in this embodiment, the air conditioning system includes multiple air conditioning devices. For example, the air conditioning device closest to a user 50 can perform a productivity improvement operation for that user 50, thereby appropriately improving the productivity of that user 50.

In this embodiment, the information processing unit 60 constituting the control means compares the average of the biometric information of all users 50 in the space 100 with the biometric information of each user 50 in the space 100. Based on the result of this comparison, the control unit 63 causes the air conditioning device to perform a productivity improvement operation. Specifically, the control unit 63 changes at least one of the airflow direction of the air conditioning device, the temperature of the air blown out, and the volume of the air blown out by the air conditioning device. In addition, the control unit 63 causes the air conditioning device to perform a productivity improvement operation based on the position of each user 50 in the space 100. Specifically, the control unit 63 causes the air conditioning device to perform a productivity improvement operation so that the airflow hits a user 50 whose productivity is thought to be declining or a user whose productivity needs to be improved. With an air conditioning system configured in this way, it is possible to appropriately improve the productivity of each user 50 in a space 100 where multiple users 50 exist, depending on the condition of each user 50.

Below, some specific examples of the control and operation of the air conditioning system are described. The information processing unit 60 may, for example, calculate and store the average value of any of the parameters of heart rate, pulse rate, heart beat interval, and pulse beat interval for all users 50 in the space 100 over a certain period of time in the past, for example within 24 hours. The information processing unit 60 may, for example, calculate and store the relevant parameters for each of the users 50 in the space 100 over a certain period of time in the past. The information processing unit 60 may then compare the calculation results of the above parameters, and the control unit 63 may control the air conditioning device based on the comparison result.

Figure 5 is a diagram showing an example of changes in the heart rate of a user 50 in embodiment 1. In Figure 5, the average value calculated by the information processing unit 60 is indicated by a dashed line. The heart rate of each user 50 fluctuates above and below this average value. For example, if the heart rate is higher than the average value, the user is considered to be in an awake state. Also, if the heart rate is lower than the average value, the user can be considered to be feeling drowsy. In this way, by comparing the biometric information of each user 50 with the biometric information of all users 50, the condition of each individual can be determined. Then, productivity improvement operations can be performed according to the individual's condition.

For example, the control means, which is composed of the information processing unit 60 and the control unit 63, may cause the air conditioning device to perform at least one of increasing the volume of the air blown out, decreasing the temperature of the air blown out, and changing the wind direction when a parameter of a particular user 50 is lower than the average parameter of the heart rate and pulse rate of all users 50 in the space 100 over a certain period of time in the past. In addition, the control means may cause the air conditioning device to perform at least one of decreasing the volume of the air blown out and increasing the temperature of the air blown out when a parameter of a particular user 50 is higher than the average parameter of the heart rate and pulse rate of all users 50 in the space 100 over a certain period of time in the past.

The air conditioning system according to this embodiment may be controlled based on the RRI (R-R Interval) of the user 50, that is, the heartbeat interval or pulse interval. FIG. 6 is a diagram showing an example of a waveform of a human heartbeat or pulse. As shown in FIG. 6, the heartbeat or pulse beats in beats such as P waves, QRS waves, and T waves. The interval from a specific R to the next R at this time is the RRI. Also, the number of Rs per unit time in FIG. 6 is the heart rate or pulse rate.

For example, when the RRI of a specific user 50 is higher than the average, the user is considered to be feeling sleepy. When the RRI of a specific user 50 is lower than the average, the user is considered to be awake. For example, the control means consisting of the information processing unit 60 and the control unit 63 may cause the air conditioning device to perform at least one of increasing the volume of the air blown out, decreasing the temperature of the air blown out, and changing the wind direction when the RRI of a specific user 50 is higher than the average RRI of all users 50 in the space 100 over a certain period of time in the past. The control means may also cause the air conditioning device to perform at least one of decreasing the volume of the air blown out and increasing the temperature of the air blown out when the RRI of a specific user 50 is lower than the average RRI of all users 50 in the space 100 over a certain period of time in the past.

The air conditioning system according to this embodiment may be controlled based on the HF component calculated from the power spectrum obtained by frequency analysis based on the RRI of the user 50, or on LF/HF, which is the ratio between the LF component and the HF component. The frequency analysis and calculation of each component are performed, for example, by the information processing unit 60. The HF component is, for example, a component with a frequency of 0.15 Hz to 0.40 Hz. The LF component is, for example, a component with a frequency of 0.04 Hz to 0.15 Hz.

For example, when the HF component or LF/HF of a specific user 50 is higher than the average value, the user is considered to be drowsy. When the HF component or LF/HF of a specific user 50 is lower than the average value, the user is considered to be awake. For example, the control means consisting of the information processing unit 60 and the control unit 63 may cause the air conditioner to perform at least one of increasing the volume of the air blown out, decreasing the temperature of the air blown out, and changing the wind direction when the HF component or LF/HF of a specific user 50 is higher than the average value of the HF component or LF/HF of all users 50 in the space 100 in the past certain time. Also, the control means may cause the air conditioner to perform at least one of decreasing the volume of the air blown out and increasing the temperature of the air blown out when the HF component or LF/HF of a specific user 50 is lower than the average value of the HF component or LF/HF of all users 50 in the space 100 in the past certain time.

In addition, at least some of the functions of the information processing unit 60, individual determination unit 61, state determination unit 62, control unit 63, etc., which constitute the control system of the air conditioning system of this embodiment, may be mounted on the first air conditioning unit 1a or the second air conditioning unit 1b, or may be provided outside each device. Some of the functions of the control system may be provided, for example, in a remote control for operating each device or in a cloud on a network.
