[0009] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0010] Embodiment 1 Fig. 1 is a configuration diagram of a building to which the air conditioning system according to the first embodiment is applied. Fig. 2 is a diagram showing temperature transitions at various points when the air conditioning means is not operating. Fig. 3 is a functional block diagram of the air conditioning system according to the first embodiment.

[0011] As shown in FIG. 1, the air conditioning system 1 is applied to a building 90. The building 90 is provided with a first space 91 which is a room, a second space 92 which is also a room, and a duct 93. For example, the first space 91 is a room intended for people living in the building 90 to spend long periods of time in, such as a living room, bedroom, or children's room. For example, the second space 92 is a non-residential room such as a bookcase, dressing room, or barn where people are not expected to spend long periods of time. In this case, the second space 92 is not provided with any equipment for adjusting the temperature inside the space. Note that the second space 92 may also be a living room. In this case, the second space 92 may be provided with equipment for adjusting the temperature inside the space.

[0012] Duct 93 is passed through the ceiling of building 90. Duct 93 has a cavity therein that serves as an air passage. The air passage connects first space 91 and second space 92. Duct 93 is connected to the interior of first space 91 at an intake port 94. Duct 93 is connected to the interior of second space 92 at an outlet port 95.

[0013] The first space 91 is provided with a lighting means 96 and a ventilation means 97. The lighting means 96 is a facility such as a window, a light-receiving window, or a glass door that allows sunlight to enter the first space 91 from the outside. The ventilation means 97 is a ventilation device that exhausts air in the first space 91 to the outside. The ventilation means 97 may be either a mechanical exhaust device or a natural exhaust device. For example, the ventilation means 97 is provided on the ceiling above the first space 91. The ventilation means 97 may also be a mechanical air supply device or a natural air intake device that takes air into the first space 91 from the outside.

[0014] The air conditioning system 1 is applied to a building 90 provided with such a first space 91, a second space 92, and an air duct. Note that the air conditioning system 1 can be applied to buildings other than those having the structure shown in Fig. 1, as long as the first space 91 is provided with a lighting means 96 and the first space 91 and the second space 92 are connected by an air duct. The air conditioning system 1 includes an air conditioning means 2, a blowing means 3, a first measuring means 4, an acquiring means 5, a relay server 6, an operating means 9, and a control means 10.

[0015] The air conditioning means 2 is provided in the first space 91. The air conditioning means 2 adjusts the temperature of the air inside the first space 91. Specifically, the air conditioning means 2 raises or lowers the temperature of the air in the first space 91 by operating. In this embodiment, the air conditioning means 2 is an air conditioner having a cooling mechanism, etc. The air conditioner is provided in an upper portion of the first space 91, above the center in the vertical direction. For example, the air conditioner is provided near the ceiling of the first space 91. The air conditioner draws in air from the upper portion of the first space 91 and generates conditioned air by changing its temperature. When the air conditioner is operating in cooling mode, it generates conditioned air by lowering the temperature of the drawn-in air. When the air conditioner is operating in heating mode, it generates conditioned air by raising the temperature of the drawn-in air. The air conditioner blows the generated conditioned air into the first space 91.

[0016] The blower means 3 is provided midway through the duct 93. The blower means 3 is a blower fan equipped with an inverter. The blower means 3 operates by rotating the blower fan. When operating, the blower means 3 generates an airflow inside the air passage that flows from the first space 91 to the second space 92, thereby sending air from the first space 91 to the second space 92. By changing the rotation speed using the inverter, the blower means 3 can control the amount of air sent from the first space 91 to the second space 92.

[0017] The first measuring means 4 is a first temperature sensor that measures the temperature of the air surrounding the air conditioning means 2. The first measuring means 4 is provided in the air conditioning means 2. The first measuring means 4 is provided in the upper part of the first space 91. As an example, the first measuring means 4 is a temperature sensor on the intake side of the air conditioner, provided either inside the housing of the air conditioner or near the housing intake port. In this case, the first measuring means 4 measures the temperature of the air sucked into the air conditioner from near the ceiling. In this case, the first measuring means 4 measures the temperature in the upper part of the first space 91.

[0018] The acquisition means 5 acquires correction information for calculating the corrected temperature. In this embodiment, the acquisition means 5 is a second measurement means 7 that measures temperature. More specifically, the second measurement means 7 is a second temperature sensor. The second measurement means 7 is provided on the floor 98 of the first space 91. The second measurement means 7 measures the surface temperature of the floor 98 or a second temperature of the air near the floor 98. As an example, hereinafter, it is assumed that the second measurement means 7 measures the temperature of the air near the floor 98 as the second temperature.

[0019] The relay server 6 is provided as a cloud server in a location separate from the building 90. The relay server 6 relays some of the communications within the air conditioning system 1.

[0020] The control means 10 is an air conditioning control device. For example, the control device is installed in the building 90. The control means 10 is connected to each device of the air conditioning system 1 wirelessly or via a wired connection so as to be able to communicate with them. The control means 10 acquires measured values ​​and the like from the first measurement means 4 and the acquisition means 5 via the relay server 6. Note that the control means 10 may acquire measured values ​​and the like directly from the first measurement means 4 and the acquisition means 5 without going through the relay server 6. The control means 10 is capable of communicating with the external information server 8 via the relay server 6. The control means 10 is capable of communicating with the operation means 9. The control means 10 controls the operation of the air conditioning means 2 and the air blowing means 3 based on the acquired information, setting information received from the operation means 9, and the like. The control of the operation includes control of starting operation, stopping operation, changing operation modes, and the like. Note that the control means 10 may be an information communication terminal such as a smartphone capable of launching a control application.

[0021] The external information server 8 is a server installed outside the building 90, such as a meteorological agency. The external information server 8 distributes weather information. The control means 10 acquires weather information from the external information server 8. The weather information includes information about the weather and information about the outside temperature. Here, the weather information includes information about solar radiation, such as the amount of solar radiation. For example, the weather information includes whether the weather is sunny, cloudy, rainy, or snowing. Note that if the weather information is used as correction information, the control means 10 may also function as the acquisition means 5.

[0022] The operation means 9 is a device that receives operations related to the operation of the air conditioning system 1 from the user. By operating the operation means 9, the user can execute control instructions such as changing the operating state of each device, changing the settings of each device, and changing the operation schedule of each device. The operation means 9 may display various information related to the air conditioning system 1. For example, the operation means 9 is a remote control for the air conditioning means 2, etc. The operation means 9 may also be an information communication terminal such as a smartphone that can launch a dedicated application. In this way, the control means 10 may have the functions of the operation means 9.

[0023] For example, the control means 10 acquires the first temperature measured by the first measurement means 4, the second temperature measured by the second measurement means 7, and the outside air temperature at a specified time interval, such as every minute. The control means 10 calculates a corrected temperature by correcting the first temperature using the second temperature, which is correction information. The control means 10 controls the air conditioning means 2 and the air blowing means 3 according to the corrected temperature. For example, the control means 10 calculates the air conditioning capacity based on the corrected temperature and the set temperature of the air conditioning means 2. The air conditioning capacity is an index value of the output at which the air conditioning means 2 is currently operating. The higher the air conditioning capacity, the higher the ratio of the current output of the air conditioning means 2 compared to the maximum output. The control means 10 controls the operation of the air conditioning means 2 based on the calculated air conditioning capacity.

[0024] Here, the corrected temperature is an estimated value of the temperature at point B, which is a representative position of the space where the user mainly engages in activities. For example, sunlight entering first space 91 by daylighting means 96 may cause the temperature of floor 98 to rise. In this case, the second temperature at point C, which is on or near floor 98, will be higher than the first temperature at point A, which represents the upper part of first space 91. In this case, when air conditioning means 2 is not operating, the air at point B will be heated by the floor surface, making the temperature of the air at point B higher than that of the air at point A.

[0025] FIG. 2 shows three graphs relating to the temperature over time at points A, B, and C when the air conditioning means is not operating. All of these graphs show examples of temperature values ​​in a room to which the air conditioning system 1 of this embodiment is not applied. In each graph, the vertical axis represents temperature and the horizontal axis represents time. The top graph represents the temperature over time at point A. The middle graph represents the estimated temperature over time at point B. The bottom graph represents the temperature over time at point C. In addition, the dotted line L0 in each graph represents the outside air temperature. The solid line L1 represents the indoor temperature at that point on a sunny day. The dashed line L2 represents the indoor temperature at that point on a cloudy day.

[0026] In this example, it is assumed that the temperature at point A changes in the same way as the outside air temperature. That is, the air at point A changes in temperature in a mountain-like pattern, with the highest temperature occurring during the day on both sunny and cloudy days.

[0027] On cloudy days, the temperature at point C changes at roughly the same rate as the outside air temperature. On sunny days, on the other hand, point C is warmed by sunlight. Therefore, on sunny days, the temperature at point C changes at a higher temperature than the outside air temperature.

[0028] On sunny days, the temperature at point B is heated by the floor at point C, and although there is a delay in the temperature rise at point C, it becomes higher than the temperature at point A. On cloudy days, the temperature at point B changes at roughly the same rate as the outside air temperature.

[0029] 1, the first space 91 is an occupied room, and therefore has the highest priority for air conditioning control for the air conditioning system 1. On the other hand, the second space 92 has a lower priority for air conditioning control for the air conditioning system 1 than the first space 91. If the correction temperature is relatively close to the set temperature, it can be considered that the first space 91 is being air-conditioned to a certain extent. In this case, the control means 10 operates the air blowing means 3.

[0030] 1 indicate airflows generated by operation of the blower means 3. Sufficiently conditioned air is also supplied to the second space 92 by the blower means 3. In this way, the air conditioning system 1 can sufficiently air-condition the first space 91 and then air-condition the second space 92.

[0031] Next, the functional configuration of the air conditioning system 1 will be described with reference to Fig. 3. As shown in Fig. 3, the control device, which is control means 10, includes, as its functions, an acquisition unit 11, a correction unit 12, an air conditioning control unit 13, and an air blow control unit 14.

[0032] The acquisition unit 11 acquires each piece of information necessary for control from each device in the air conditioning system 1 at specified time intervals, such as every minute. For example, the acquisition unit 11 acquires device operation information from the air conditioning means 2 and the air blowing means 3. The acquisition unit 11 acquires the measured values ​​of the first temperature and the second temperature from the first measurement means 4 and the second measurement means 7, which are the acquisition means 5, respectively. The acquisition unit 11 may acquire weather information from the external information server 8 as a function of the acquisition means 5.

[0033] The acquisition unit 11 may acquire a measured value of the outside air temperature, which is the temperature outside, from an external temperature sensor (not shown). The outside air temperature may be the temperature not only outside the building 90, but also in a parking lot provided in the building 90, a space under the floor of the building 90, an outdoor space that is not subject to air conditioning, or the like.

[0034] The correction unit 12 calculates the correction value using the correction information acquired by the acquisition means 5. The correction unit 12 may also calculate the correction value using the first temperature acquired by the first measurement means 4. The correction unit 12 calculates the corrected temperature by adding the calculated correction value to the measured first temperature.

[0035] The correction value and the correction temperature can be calculated as various values. The correction unit 12 calculates the correction value so that the correction temperature is equal to or greater than the first temperature and equal to or less than the second temperature. In this embodiment, the correction value is calculated according to the first temperature and the second temperature. The correction value calculated according to the first temperature and the second temperature is also referred to as the first correction value.

[0036] Specifically, the correction value is calculated according to the difference between the first temperature and the second temperature. At this time, if the first temperature is smaller than the second temperature, the correction unit 12 calculates the correction value so that it is a positive value. For example, the correction unit 12 calculates the correction value from the first temperature and the second temperature using a mathematical model that calculates the correction value based on the first temperature and the second temperature. If the first temperature is larger than the second temperature, the correction unit 12 calculates the correction value so that it is a negative value. The correction unit 12 calculates the correction value so that the absolute value of the correction value increases as the absolute value of the difference between the first temperature and the second temperature increases. The correction unit 12 calculates the correction value so that the absolute value of the correction value is smaller than the absolute value of the difference between the first temperature and the second temperature. At this time, the correction unit 12 calculates the correction value so that it is a value between -3.0°C and +3.0°C.

[0037] The air conditioning control unit 13 controls the operation of the air conditioning means 2. At this time, the air conditioning control unit 13 determines the air conditioning capacity of the air conditioning means 2 using the corrected temperature calculated by the correction unit 12. For example, the air conditioning control unit 13 determines the air conditioning capacity based on the difference between the corrected temperature and the set temperature.

[0038] The air blowing control unit 14 controls the operation of the air blowing means 3. In this case, the air blowing control unit 14 controls the air blowing means 3 so that the air conditioning means 2 and the air blowing means 3 operate in cooperation with each other. For example, when the operation mode of the air conditioning means 2 is changed, the air blowing control unit 14 stops the operation of the air blowing means 3 that is currently operating.

[0039] Furthermore, the air blowing control unit 14 may operate the air blowing unit 3 instead of the air conditioning unit 2. Specifically, when all of the following conditions are met, the air blowing control unit 14 may start the operation of the air blowing unit 3 that has been stopped. That is, when the air conditioning unit 2 is stopped, and the air blowing control unit 14 determines that the outside air temperature is lower than the first air blowing threshold, and the corrected temperature is equal to or higher than the second air blowing threshold, and the first temperature is equal to or higher than the third air blowing threshold, the air blowing control unit 14 may start the operation of the air blowing unit 3 that has been stopped.

[0040] Next, an example of the temperature transition in the first space 91 during cooling and heating will be described with reference to FIGS. Fig. 4 is a diagram showing an example of cooling operation when the air conditioning system according to embodiment 1 is not applied. Fig. 5 is a diagram showing an example of cooling operation performed by the air conditioning system according to embodiment 1. Fig. 6 is a diagram showing an example of heating operation when the air conditioning system according to embodiment 1 is not applied. Fig. 7 is a diagram showing an example of heating operation performed by the air conditioning system according to embodiment 1.

[0041] 4 to 7, the axes of each graph and the temperatures indicated by each line are the same as those in the graph in FIG. 2. In FIGS. 4 to 7, a line segment indicating the set temperature T0 of the air conditioning means 2 is drawn. In FIGS. 4 to 7, time periods D1 and D2 represent time periods when the air conditioning means 2 is in cooling or heating operation. In time periods other than time periods D1 and D2, the air conditioning means 2 is stopped.

[0042] 4 shows temperature transitions at points A, B, and C in the first space 91 when the air conditioning system 1 in the first embodiment is not applied, that is, when the air conditioning means 2 is controlled based on the conventional technology. In FIG. 4, the air conditioning means 2 performs cooling operation.

[0043] At points A and B, the temperatures drop rapidly after cooling operation begins. On cloudy days, the temperatures at points A and B are relatively stably controlled to the set temperature T0. That is, air conditioning is performed sufficiently in the first space 91. On the other hand, on sunny days, the temperature at point C is highest and the temperature at point A is lowest. The temperature at point B remains below the set temperature T0 for a long time. For example, at point A, a short circuit of airflow may occur, i.e., the air blown out from the air conditioning unit 2 may return to the air intake of the air conditioning unit 2 without circulating sufficiently within the first space 91. In such a case, the temperature in the upper part of the first space 91 does not rise as high as the temperatures near the floor 98 and at point B. During time period D2, even though the temperature at point B has not yet reached the set temperature T0, control is performed to reduce the air conditioning capacity of the air conditioning unit 2 when the temperature at point A falls below the set temperature T0. In this case, the temperature at point A is likely to rise due to the influence of the temperature at point B. As a result, the temperature at point A fluctuates wildly around the set temperature T0. Furthermore, point B, which is a representative point of the temperature felt by people in first space 91, is in a state of insufficient air conditioning.

[0044] FIG. 5 is a diagram showing cooling operation when the air conditioning system 1 in the first embodiment is applied. That is, the control means 10 calculates a correction temperature and controls the air conditioning means 2 based on the correction temperature. At this time, the operation of the air conditioning means 2 can be controlled so that the temperature at point B follows the set temperature T0. Therefore, the insufficient air conditioning at point B can be resolved. Furthermore, in the air conditioning system 1, resolving the insufficient air conditioning at point B means that the first space 91 has been sufficiently air-conditioned.

[0045] FIG. 6 shows the temperature transitions at points A, B, and C in the first space 91 during heating operation when the air conditioning means 2 is controlled based on conventional technology. Due to the influence of solar radiation, the temperature at point C is highest and the temperature at point A is lowest on sunny days. When the air conditioning means 2 operates under these conditions, the air conditioning means 2 is controlled so that the temperature at point A becomes the set temperature T0. As a result, the temperature at point B continues to be higher than the set temperature T0, i.e., on sunny days, point B becomes over-air-conditioned.

[0046] FIG. 7 is a diagram showing heating operation when the air conditioning system 1 in the first embodiment is applied. That is, the control means 10 calculates a correction temperature and controls the air conditioning means 2 based on the correction temperature. At this time, the operation of the air conditioning means 2 can be controlled so that the temperature at point B follows the set temperature T0. Therefore, excessive air conditioning at point B can be eliminated. Furthermore, in the air conditioning system 1, elimination of excessive air conditioning at point B means that the first space 91 has been sufficiently air-conditioned.

[0047] Although not shown, in winter when heating is in operation and the weather is cloudy with little solar radiation, floor 98 heats up more slowly than the air, and therefore its temperature is lower than points A and B. In this case, floor 98 absorbs heat from point B. As a result, point A has the highest temperature and point C has the lowest temperature. In conventional technology, the temperature at point B can be lower than the temperature at point A. That is, the temperature at point B cannot reach the set temperature, and insufficient air conditioning can occur. In the first embodiment, even in winter when solar radiation is scarce, air conditioning means 2 is controlled so that point B reaches the set temperature. This can prevent insufficient air conditioning at point B.

[0048] Next, the cooperative operation with the air blowing means 3 will be described with reference to Figures 8 and 9. On the condition that the first space 91 is sufficiently conditioned, the air blowing means 3 controls the movement of air from the first space 91 to the second space 92. Fig. 8 is a flowchart showing the cooling operation of the air conditioning system according to embodiment 1. Fig. 9 is a flowchart showing the heating operation of the air conditioning system according to embodiment 1.

[0049] 8 is a flowchart when the air conditioning means 2 is performing cooling operation. The control means 10 starts the operation of the flowchart at a specified cycle, such as every minute.

[0050] In step S01, the acquisition unit 11 of the control means 10 acquires instruction information from the user, operation information of each device, information on the first temperature detected by the first measurement means 4, information on the second temperature which is correction information acquired by the acquisition means 5, outside air temperature, and weather information. The instruction information includes the setting of the operation mode, the set temperature, etc. Note that the acquisition unit 11 does not need to acquire other information as long as it acquires the set temperature, operation information, information on the first temperature, and information on the second temperature.

[0051] Then, in step S02, the correction unit 12 calculates a correction value and a correction temperature based on the information acquired in step S01. The air conditioning control unit 13 controls the operation of the air conditioning means 2 based on the correction temperature.

[0052] Thereafter, in step S03, the air blowing control unit 14 determines whether the air blowing means 3 is stopped or not.

[0053] If it is determined in step S03 that the air blowing means 3 is stopped, the operation of step S04 is performed. In step S04, the air blowing control unit 14 determines, as a first determination, whether the absolute value of the difference between the corrected temperature calculated in step S02 and the set temperature of the air conditioning means 2 is equal to or less than a first threshold value. The first threshold value is set to an arbitrary positive value in advance. As an example, the first temperature is 1.0°C. If the absolute value of the difference between the corrected temperature and the set temperature of the air conditioning means 2 is equal to or less than the first threshold value, the air conditioning system 1 determines that the first space 91 is sufficiently air-conditioned.

[0054] In step S04, if the absolute value of the difference between the calculated corrected temperature and the set temperature of the air conditioning means 2 is equal to or less than the first threshold, the first determination is Yes, and the operation of step S05 is performed. In step S05, the air blowing control unit 14 starts operation of the air blowing means 3, which had been stopped. Thereafter, the operation of the flowchart ends.

[0055] In step S04, if the absolute value of the difference between the calculated corrected temperature and the set temperature of the air conditioning unit 2 is greater than the first threshold value, the first determination is No, and the operation of the flowchart ends. That is, the air blowing unit 3 remains stopped.

[0056] If it is determined in step S03 that the air blowing means 3 is operating, the operation of step S06 is performed. In step S06, the air blowing control unit 14 determines, as a second determination during cooling, whether the difference obtained by subtracting the set temperature of the air conditioning means 2 from the correction temperature is equal to or greater than a second threshold. The second threshold is set in advance. For example, the second threshold may be any value greater than the first threshold. As an example, the second temperature is 2.0°C. If air conditioning is insufficient during cooling, the correction temperature will be significantly higher than the set temperature. If the difference obtained by subtracting the set temperature of the air conditioning means 2 from the correction temperature is equal to or greater than the second threshold, the air conditioning system 1 determines that air conditioning is insufficient in the first space 91.

[0057] In step S06, if the difference between the corrected temperature and the set temperature is equal to or greater than the second threshold, the second determination during cooling is Yes, and the operation of step S07 is performed. In step S07, the air blowing control unit 14 stops the air blowing means 3 that was operating. That is, because air blowing by the air blowing means 3 may exacerbate the insufficient air conditioning of the first space 91, this air blowing is stopped. Thereafter, the operation of the flowchart ends.

[0058] In step S06, if the difference between the corrected temperature and the set temperature is smaller than the second threshold value, the second determination during cooling becomes No, and the operation of the flowchart ends. That is, the air blowing means 3 continues to operate.

[0059] 9 is a flowchart when the air conditioning means 2 is performing heating operation. The control means 10 starts the operation of the flowchart at a specified cycle, such as every minute. The same first and second threshold values ​​as those used in cooling operation may be used in heating operation as well.

[0060] The operations from step S11 to step S15 are the same as the operations from step S01 to step S05 in the flowchart of Fig. 8. For example, in step S14, a first determination similar to that in step S04 is performed.

[0061] If it is determined in step S13 that the air blowing means 3 is operating, the operation of step S16 is performed. In step S16, the air blowing control unit 14 determines, as a second determination during heating, whether the difference obtained by subtracting the correction temperature from the set temperature of the air conditioning means 2 is equal to or greater than a second threshold value. If air conditioning is insufficient during heating, the correction temperature will be significantly lower than the set temperature. If the difference obtained by subtracting the correction temperature from the set temperature of the air conditioning means 2 is equal to or greater than the second threshold value, it is determined that air conditioning is insufficient in the first space 91 in the air conditioning system 1.

[0062] In step S16, if the difference obtained by subtracting the correction temperature from the set temperature is equal to or greater than the second threshold value, the second determination during heating is Yes, and the operation of step S17 is performed. In step S17, the air blowing control unit 14 stops the air blowing means 3 that was operating. That is, because air blowing by the air blowing means 3 may exacerbate the insufficient air conditioning of the first space 91, this air blowing is stopped. Thereafter, the operation of the flowchart ends.

[0063] In step S16, if the difference between the set temperature and the corrected temperature is smaller than the second threshold value, the second determination during heating becomes No, and the operation of the flowchart ends. That is, the air blowing means 3 continues to operate.

[0064] According to the first embodiment described above, the air conditioning system 1 includes the air conditioning unit 2, the air blowing unit 3, the first measurement unit 4, the acquisition unit 5, and the control unit 10. In conventional technology, a temperature discrepancy may occur between point A and point B, particularly due to the floor 98 being heated by sunlight. In this case, if a cooling operation is performed, insufficient air conditioning may occur. If the air blowing unit 3 blows air in this state, the insufficient air conditioning in the first space 91 is exacerbated. Air not at the desired temperature is supplied to the second space 92. Furthermore, if a heating operation is performed, excessive air conditioning occurs, resulting in a deterioration in energy-saving performance. In this case, air not at the desired temperature is supplied to the second space 92. According to the present embodiment, the first temperature at point A is corrected to calculate a corrected temperature. The air conditioning unit 2 and the air blowing unit 3 are controlled based on the corrected temperature. Since control is performed using a temperature more suitable for control than the first temperature, the air conditioning system 1 can control the temperature of the first space 91 to a temperature more suitable for the user. As a result, it is possible to improve the comfort of the user and also to prevent deterioration of energy-saving performance.

[0065] Furthermore, the acquisition means 5 is a second measurement means 7. In the air conditioning system 1, a correction value is calculated based on the first temperature at point A and the second temperature at point C. Therefore, the air conditioning system 1 can calculate a correction temperature that indicates point B, which is an intermediate position between points A and C, without directly measuring the temperature of point B. As a result, user comfort can be improved. Furthermore, the correction value is calculated to be a positive or negative value depending on the relationship between the first temperature and the second temperature. The correction value is corrected to be a value within an appropriate range. By performing these controls, the air conditioning system 1 can improve the accuracy of air conditioning control of the first space 91.

[0066] Furthermore, in the air conditioning system 1, the operation of the air blower 3 is started or stopped depending on the difference between the correction temperature and the set temperature. For example, when the absolute value of the difference between the correction temperature and the set temperature is equal to or less than a first threshold, the operation of the air blower 3 is started. Therefore, the air conditioning system 1 can automatically start the operation of the air blower 3 when the first space 91 is sufficiently air-conditioned. For example, when a cooling operation is being performed, if the difference obtained by subtracting the set temperature from the correction temperature is equal to or greater than a second threshold, the operation of the air blower 3 is stopped. Therefore, the air conditioning system 1 can automatically stop the operation of the air blower 3 when the first space 91 is not sufficiently cooled and is insufficiently air-conditioned. For example, when a heating operation is being performed, if the difference obtained by subtracting the correction temperature from the set temperature is equal to or greater than the second threshold, the operation of the air blower 3 is stopped. Therefore, the air conditioning system 1 can automatically stop the operation of the air blower 3 when the temperature of the first space 91 is not sufficiently raised and is insufficiently air-conditioned. Furthermore, the first threshold and the second threshold are set to be within an appropriate range. By performing these controls, the air conditioning system 1 can improve the accuracy of the air conditioning control of the first space 91.

[0067] Note that air may be blown from the first space 91 not only to the second space 92 but also to a plurality of rooms provided in the building 90. In this case, a new air passage may be formed by providing a new duct, branching an existing duct 93, or the like. Furthermore, an opening / closing means such as a damper may be provided inside the duct. The volume of air blown to each room may be adjusted by the opening / closing means.

[0068] Here, the air conditioning system 1 of this embodiment is similar to conventional central air conditioning systems in that it controls the temperature of multiple rooms in a single building at the same time. However, the air conditioning system 1 differs from conventional central air conditioning systems in that it sends air to each room from a room intended for people to spend a long time in. In particular, the air conditioning system 1 differs from central air conditioning systems that prioritize the room to which air is sent in that it prioritizes air conditioning control of the first space 91, which is a living room, so that people can spend time there. Furthermore, the air conditioning system 1 can be realized with a minimum configuration of ducts 93 connecting at least two rooms. This makes the air conditioning system 1 easy to install. Furthermore, the air conditioning system 1 is advantageous in terms of cost compared to central air conditioning systems because it does not require a large air conditioner to control the temperature of the entire building and does not require a dedicated space for installing such a large air conditioner.

[0069] Unlike the first example in which the second temperature is used as the correction information, the correction unit 12 may calculate the corrected temperature using other information as the correction information. In this case, the acquisition means 5 acquires the corresponding correction information.

[0070] In a second example of correction, correction unit 12 may calculate the correction value using weather information as correction information. That is, in the second example, correction unit 12 calculates the corrected temperature by adding a second correction value calculated according to the weather information to the first temperature.

[0071] At this time, the correction unit 12 calculates the second correction value so that the stronger the insolation is, the larger the value becomes. For example, when the weather information includes information that the weather is sunny as information about insolation, the correction unit 12 calculates the second correction value so that the value becomes a positive value. When the weather information includes information that the weather is cloudy, rainy, or snowing as information about insolation, the correction unit 12 calculates the second correction value so that the value becomes a negative value.

[0072] In the second example, the correction unit 12 calculates the second correction value to be a value between −3.0° C. and +3.0° C. Note that the correction unit 12 may calculate the second correction value so that the higher the amount of ultraviolet rays included in the weather information as information about solar radiation, the larger the value becomes.

[0073] In this way, in the second example, the air conditioning system 1 can calculate the corrected temperature by taking into account the influence of solar radiation from the weather information, without measuring the second temperature.

[0074] In a third example of correction, the correction unit 12 calculates a third correction value and a correction temperature based on the air conditioning capacity and the outside air temperature. Specifically, the acquisition unit 11, as the acquisition means 5, calculates the air conditioning capacity of the air conditioning means 2 based on the first temperature and the set temperature of the air conditioning means 2. The acquisition means 5 measures the outside air temperature or acquires weather information including the outside air temperature. The correction unit 12 calculates the third correction value according to the relationship between the outside air temperature and the air conditioning capacity. The correction unit 12 calculates the corrected temperature by adding the third correction value to the first temperature. In this case, the correction unit 12 calculates the third correction value so that it is a value between -3.0°C and +3.0°C.

[0075] The correction unit 12 calculates the third correction value according to the level of the air conditioning capacity relative to the outside temperature, i.e., the operating load of the air conditioning means 2 estimated from the outside temperature. At this time, the correction unit 12 calculates the comparison value from the outside temperature using a comparison model, which is a mathematical model. The comparison value is an index value of the standard air conditioning capacity estimated from the outside temperature when there is no influence of solar radiation.

[0076] The correction unit 12 uses different comparison models when the air conditioning means 2 is performing cooling operation and when it is performing heating operation. When heating operation is performed, the comparison value during heating output by the heating comparison model becomes larger as the outside temperature becomes lower. When cooling operation is performed, the comparison value during cooling output by the cooling comparison model becomes larger as the outside temperature becomes higher.

[0077] When heating operation is being performed, if the air conditioning capacity is lower than the comparison value during heating, the correction unit 12 calculates the third correction value so that it becomes a positive value. Specifically, when heating operation is being performed, since it is winter, the air conditioning means 2 operates to raise the temperature of the first space 91. When the air conditioning capacity is lower than the comparison value during heating, it is assumed that sunlight is heating the floor 98, making it easier for the first space 91 to warm up. In other words, it is assumed that the temperature at point B is higher than the first temperature. Therefore, the correction unit 12 calculates the third correction value so that the correction temperature is higher than the first temperature.

[0078] When heating operation is in progress, if the air conditioning capacity is higher than the comparison value during heating, the correction unit 12 calculates the third correction value so that it becomes a negative value. Specifically, for example, when there is no sunlight, the temperature of the floor 98 does not rise. When the air conditioning capacity is higher than the comparison value during heating, the temperature of the floor 98 is lower than in the standard case, and it is assumed that the first space 91 is in a situation where it is more difficult to heat up. In other words, the temperature of point B is considered to be lower than the first temperature. For this reason, the correction unit 12 calculates the third correction value so that the correction temperature is lower than the first temperature.

[0079] When cooling operation is being performed, if the air conditioning capacity is lower than the comparison value during cooling, the correction unit 12 calculates the third correction value to be a negative value. Specifically, when cooling operation is being performed, because it is summer, the air conditioning means 2 operates to lower the temperature of the first space 91. If the air conditioning capacity is lower than the comparison value during cooling, it is assumed that the temperature of the floor 98 is lower than in the standard case due to the lack of sunlight, and therefore the first space 91 is more likely to be cooled. In other words, it is assumed that the temperature at point B is not higher than the first temperature. Therefore, the correction unit 12 calculates the third correction value so that the correction temperature is lower than the first temperature.

[0080] When the air conditioning capacity is higher than the comparison value during cooling operation during cooling, the correction unit 12 calculates the third correction value so that it becomes a positive value. Specifically, when the air conditioning capacity is lower than the comparison value during cooling, it is assumed that the temperature of the floor 98 is higher than in the standard case due to the influence of sunlight, and therefore the first space 91 is less likely to be cooled. In other words, the temperature at point B is considered to be higher than the first temperature. Therefore, the correction unit 12 calculates the third correction value so that the correction temperature is higher than the first temperature.

[0081] In this way, in the third example, the air conditioning system 1 can calculate a corrected temperature that estimates the influence of solar radiation from the air conditioning capacity and the outside air temperature, without measuring the second temperature.

[0082] In a fourth example of correction, the correction unit 12 calculates a fourth correction value and a corrected temperature according to the thermal load of the first space 91. Specifically, the acquisition means 5 acquires correction information related to the thermal load of the first space 91. The thermal load is an index value indicating how easily the first space 91 heats up and cools down. The higher the thermal load, the easier the first space 91 heats up. In other words, the higher the thermal load, the more likely it is that the temperature at point B is high. Therefore, the correction unit 12 calculates the fourth correction value so that it becomes larger the higher the thermal load. In this case, the correction unit 12 calculates the fourth correction value so that it is a value between -3.0°C and +3.0°C. The correction unit 12 calculates the corrected temperature by adding the fourth correction value to the first temperature.

[0083] As an example, the acquisition means 5 is a presence detection means that detects the presence of a person in the first space 91. The presence detection means detects the presence of a person in the first space 91 based on at least one of operation information of a remote control that is the operation means 9, input information to the remote control, and position information of the remote control. Note that the remote control may be a smartphone that serves as the operation means 9.

[0084] When the presence detection means detects the presence of a person in the first space 91, the correction unit 12 calculates the fourth correction value to be a positive value. That is, when a person is present in the first space 91, it is determined that the heat load of the first space 91 is high due to the sensible heat of the person.

[0085] As another example, the acquisition means 5 is a temperature sensor that measures the temperature of the light collecting means 96 or the temperature of the wall of the first space 91 as the correction information. In this case, the acquisition means 5 may measure the temperature of the light collecting means 96 or the temperature of the air around the light collecting means 96, or may measure the temperature of the wall of the first space 91 or the temperature of the air around the wall. The correction unit 12 calculates the fourth correction value so that the higher the temperature measured by the acquisition means 5, the larger the value.

[0086] The correction unit 12 may calculate an overall correction value by adding together at least two of the first correction value, second correction value, third correction value, and fourth correction value described above. In this case, the correction unit 12 calculates the corrected temperature by adding the overall correction value to the first temperature. In this way, the correction unit 12 calculates a corrected temperature that takes into account the influence of temperature changes at point B caused mainly by solar radiation. This makes it possible to more accurately estimate the temperature of point B, which is the target of air conditioning in the first space 91. In this disclosure, the first correction value, second correction value, third correction value, fourth correction value, and overall correction value are all referred to as correction values.

[0087] The air conditioning means 2 does not have to be an air conditioner that generates conditioned air. For example, the air conditioning means 2 is a radiator for heating and cooling in a heat pump type hot water / air conditioner (ATW). A heat pump type hot water air conditioner generates hot water as a heat medium or cold water as a refrigerant in a radiator. A heat pump type hot water air conditioner heats or cools the temperature around the radiator by flowing a heat medium or refrigerant through the radiator. That is, in heating operation, the heat pump type hot water air conditioner flows a heat medium through the radiator. In cooling operation, the heat pump type hot water air conditioner flows a refrigerant through the radiator. The radiator may be provided with a means for generating airflow. In this way, the radiator regulates the temperature of the air in the first space 91.

[0088] When the air conditioning means 2 is a radiator of a heat pump type hot water supply / air conditioner, the first measuring means 4 is provided at a position slightly away from the radiator and measures the temperature of the air around the radiator as the first temperature. This is because if the first measuring means 4 were attached directly to the radiator, it would be impossible to accurately measure the temperature of the air in the first space 91.

[0089] The air conditioning means 2 may be a floor heating device provided on the floor 98 of the first space 91. In this case, an air conditioner need not be provided in the first space 91. When floor heating is performed, the temperature at point C rises regardless of whether there is solar radiation or not. In this case, the first measurement means 4 may measure the temperature around the floor 98. The acquisition means 5 may measure the temperature of the daylighting means 96 or acquire weather information as the correction information. Even in this case, as in the first embodiment, the corrected temperature calculated by the correction unit 12 is the estimated temperature at point B. An air conditioner may be provided in the first space 91 for cooling operation.

[0090] The second measuring means 7 may be a sensor that detects electromagnetic waves emitted from an object in accordance with its temperature. FIG. 10 is a configuration diagram of a building to which a modified example of the air conditioning system according to the first embodiment is applied.

[0091] As shown in FIG. 10 , the second measurement means 7 is a thermal detection sensor that measures the temperature of the floor 98. The thermal detection sensor is a thermal image sensor that detects electromagnetic waves emitted from an object. The electromagnetic waves are infrared rays and have a wavelength corresponding to the surface temperature of the object. The second measurement means 7 is provided above the first space 91. For example, the second measurement means 7 is attached to the housing of the air conditioning means 2. The second measurement means 7 measures the temperature of the floor 98 as the second temperature, as shown in area E.

[0092] According to this modification, the second measuring means 7 does not need to be provided near the floor 98. Therefore, the second measuring means 7 can be used which is easy to install and does not impair livability.

[0093] The heat detection sensor may be provided not on the housing of the air conditioning unit 2 but on the ceiling of the first space 91, a wall surface near the ceiling, or the like.

[0094] Embodiment 2 Fig. 11 is a configuration diagram of a building to which an air conditioning system according to the second embodiment is applied. Fig. 12 is a functional block diagram of the air conditioning system according to the second embodiment. Note that parts that are the same as or equivalent to parts according to the first embodiment are given the same reference numerals, and a description of these parts will be omitted.

[0095] As shown in FIGS. 11 and 12 , in the second embodiment, the air conditioning system 1 further includes an agitation means 20. The control means 10 is communicatively connected to the agitation means 20. The acquisition unit 11 of the control means 10 acquires operation information of the agitation means 20. The control means 10 controls the operation of the agitation means 20. That is, the control means 10 controls the operation, stop, air volume, wind direction, etc. of the agitation means 20. In this case, the control means 10 controls the agitation means 20 in conjunction with the air blowing means 3.

[0096] The agitator 20 is provided in the first space 91. The agitator 20 is a means for creating a change in airflow. In this embodiment, the agitator 20 is a blower fan. When the agitator 20 is operating, it blows air toward the first space 91. The agitator 20 may be a floor-standing type, a ceiling-mounted type, or a wall-mounted type, and the installation form thereof is not limited.

[0097] The agitator 20 is capable of changing the direction of the airflow it blows out. The agitator 20 may have a fan swing mechanism, or may have louvers and flaps at the airflow outlet. The agitator 20 is capable of changing at least one of the left-right and up-down directions of the airflow it blows out by using these mechanisms. The agitator 20 is capable of changing the volume of the airflow it blows out. The airflow direction of the agitator 20 may also be controlled to change at regular intervals.

[0098] In the air conditioning system 1, when the blower means 3 operates, the first space 91 becomes under negative pressure relative to the outside air, and the amount of outside air introduced from the ventilation means 97 increases. For this reason, high-temperature outside air is introduced into the first space 91 during cooling in the summer. Low-temperature outside air is introduced into the first space 91 during heating in the winter. If the amount of outside air introduced increases, air conditioning may become insufficient, and air may be transported to the second space 92 without the first space 91 being sufficiently temperature-controlled. Furthermore, in winter, there is a possibility of under-floor cooling, where the temperature of the floor 98 drops.

[0099] By providing the stirring means 20, the air inside the first space 91 is stirred, and temperature unevenness can be eliminated. As a result, it is possible to prevent insufficient air conditioning in the first space 91, insufficient air conditioning in the second space 92, and the occurrence of cold floors.

[0100] Next, the operation of the air conditioning system 1 provided with the agitation means 20 will be described with reference to FIGS. Fig. 13 is a flowchart showing the cooling operation of the air conditioning system according to embodiment 2. Fig. 14 is a flowchart showing the heating operation of the air conditioning system according to embodiment 2.

[0101] In the flowchart of FIG. 13, the operations from step S21 to step S27 are the same as the operations from step S01 to step S07 in the flowchart of FIG. 8. However, in step S21, the acquisition unit 11 further acquires operation information of the agitation means 20. After the operation of step S25, the operation of step S28 is performed. In step S28, the control means 10 starts operation of the agitation means 20, which had been stopped. That is, in the second embodiment, when the operation of the blower means 3 is started, the operation of the agitation means 20 is also started. Thereafter, the operation of the flowchart ends.

[0102] In the flowchart of Fig. 14, the operations from step S31 to step S37 are the same as the operations from step S11 to step S17 in the flowchart of Fig. 9. However, in step S31, the acquisition unit 11 further acquires operation information of the agitation means 20. After the operation of step S35, the operation of step S38 is performed. In step S38, the control means 10 starts the operation of the agitation means 20 that had been stopped. Thereafter, the operation of the flowchart ends.

[0103] According to the second embodiment described above, the air conditioning system further includes the agitation means 20. The agitation means 20 can eliminate temperature unevenness in the first space 91. As a result, the air conditioning system 1 can improve user comfort and energy-saving performance.

[0104] The agitating means 20 may not be a blower fan, but may be louvers and flaps provided on an air conditioner, which is the air conditioning means 2. In this case, the agitating means 20 changes the direction of the conditioned air blown out from the air conditioner. Even in this case, the air inside the first space 91 can be agitated.

[0105] Embodiment 3 Fig. 15 is a functional block diagram of an air conditioning system according to the third embodiment. Fig. 16 is a diagram showing an overview of a neural network model. Fig. 17 is a flowchart of the learning process of the learning device according to the third embodiment. Fig. 18 is a flowchart of the inference process performed by the control means of the air conditioning system according to the third embodiment. Note that parts that are the same as or equivalent to parts in the first or second embodiment are given the same reference numerals. Explanation of these parts will be omitted.

[0106] 15, in the third embodiment, the air conditioning system 1 further includes a learning device 30 as a learning means. The learning device 30 uses the history of time transitions regarding the past correction information and correction values ​​performed in the first or second embodiment as training data, and generates a learned correction model using a machine learning technique.

[0107] The control means 10 uses the correction model to infer at least one of a model correction value that is added to the first temperature to obtain the correction temperature, and a correction time period in which the correction value needs to be added to the first temperature. In this embodiment, the control means 10 infers at least one of the model correction value and the correction time period by inputting the first temperature and the second temperature into the correction model.

[0108] When the control means 10 infers a model correction value, it adds the model correction value to the first temperature to obtain the corrected temperature. When the control means 10 infers a correction time period in which a correction value needs to be added to the first temperature, it adds the correction value calculated by the correction unit 12 during the correction time period to the first temperature to obtain the corrected temperature. In this case, the correction value may be any of the first correction value, second correction value, third correction value, fourth correction value, and overall correction value. When the correction unit 12 of the control means 10 infers both the model correction value and the time period, it adds the model correction value to the first temperature during the correction time period to obtain the corrected temperature. In either case, the control means 10 performs the control described in embodiment 1 or 2 based on the calculated corrected temperature. Note that, hereinafter, an example will be described in which the control means 10 uses a correction model to infer the model correction value and the correction time period.

[0109] The learning device 30 has as its functions a data acquisition unit 31, a model generation unit 32, and a model storage unit 33. The hardware configuration of the learning device 30 is similar to that of the control device, which is the control means 10. Note that the function of the model storage unit 33 may be provided in a device other than the learning device 30, such as the control means 10.

[0110] The data acquisition unit 31 acquires learning data from past history. The learning data includes information in which the measured first temperature, the measured second temperature, and the calculated correction value are associated with each other. The learning data includes the time when the first temperature was measured, the time when the second temperature was measured, and the time when the correction value was calculated. In other words, the learning data includes the time transition of the first temperature, the time transition of the second temperature, and the time transition of the correction value.

[0111] The model generation unit 32 generates a correction model by performing machine learning using the learning data acquired by the data acquisition unit 31. The correction model is a model for inferring at least one of a model correction value and a correction time period based on the first temperature and the second temperature. For example, the model generation unit 32 performs machine learning using a supervised learning method.

[0112] The model generation unit 32 stores the generated correction model in the model storage unit 33. Alternatively, the model generation unit 32 updates the correction model stored in the model storage unit 33 to the newly generated correction model.

[0113] Figure 16 shows a three-layer neural network as an overview of a neural network model. The neural network is composed of input layers X1-X3 consisting of multiple neurons, intermediate layers Y1-Y2 consisting of multiple neurons, and output layers Z1-Z3 consisting of multiple neurons. The intermediate layers are also called hidden layers and may have one or more layers. In a three-layer neural network with one intermediate layer, when multiple inputs are input to the input layers X1-X3, the values ​​are multiplied by weights W1 (w11-w16) and then input to the intermediate layers Y1-Y2. The outputs from the intermediate layers Y1-Y2 resulting from these inputs are multiplied by weights W2 (w21-w26) and output from the output layers Z1-Z3. The final output result depends on the values ​​of the weights W1 and W2.

[0114] The neural network in the model generation unit 32 learns the "time course of the correction value" by so-called supervised learning in accordance with the learning data acquired by the data acquisition unit 31 and created based on a combination of the "first temperature," the "second temperature," and the "time course of the correction value." That is, the neural network learns by inputting the "first temperature" and the "second temperature" into the input layer and adjusting the weights W1 and W2 so that the result output from the output layer approaches the "time course of the correction value," which is the correct data (result). The model generation unit 32 generates and outputs a learned correction model by executing the above-mentioned learning. When the "time course of the correction value" is output, only the correction value may be extracted and output as a "model correction value," or only the time course may be extracted and output as a "correction time zone."

[0115] In addition, although the present example describes an example in which supervised learning is applied to the learning algorithm in the model generation unit 32, the learning algorithm is not limited to this. For example, techniques such as reinforcement learning, unsupervised learning, and semi-supervised learning may be applied as the learning algorithm. Furthermore, deep learning, which learns to extract features themselves, may be applied as the learning algorithm. Furthermore, the model generation unit 32 may perform machine learning according to other known techniques, such as linear programming (LP), integer programming (IP), genetic algorithm (GA), particle swarm optimization (PSO), constrained optimization, and simulated annealing.

[0116] The learning data used by the model generation unit 32 may be historical information on the first temperature, the second temperature, and the correction value accumulated in another air conditioning system other than the air conditioning system 1. The other air conditioning system may be a system applied in the same area, or may be a system operating independently in another area. Here, the same area may refer to multiple buildings in the same region. This is because the relationship between solar radiation and outdoor temperature is similar in the same area. Furthermore, air conditioning systems collected as learning data may be added to or removed from the targets at any time. A correction model that has been trained for a certain air conditioning system may be retrained for the air conditioning system 1 to update it.

[0117] 15, the control means 10 includes, as functions, a model storage unit 15 and an inference unit 16. When an inference process is performed, the acquisition unit 11 acquires the latest first temperature and second temperature as inference data.

[0118] The model storage unit 15 stores the latest correction model. For example, when the correction model is updated in the learning device 30, the latest correction model is also stored in the model storage unit 15. The inference unit 16 infers a model correction value and a correction time period based on the inference data, and outputs the inference results.

[0119] The flowchart shown in FIG. 17 starts at an arbitrary timing, such as when a specified period of time has elapsed since the previous learning process, or when a command to perform learning is issued.

[0120] In step S41, the data acquisition unit 31 acquires learning data from the history of the air conditioning system 1. The history of the air conditioning system 1 may be stored in any device, such as the control means 10 or the relay server 6. Then, in step S42, the model generation unit 32 performs machine learning calculations to generate a correction model. Then, in step S43, the model generation unit 32 updates the correction model stored in the model storage unit 33 to the latest correction model generated in step S42. Then, the operation of the flowchart ends.

[0121] The flowchart shown in Fig. 18 may start, for example, when an operation to start driving that day is received from the user, or when a specified time arrives. Also, the flowchart shown in Fig. 19 may start when a specified time has elapsed since the previous inference process.

[0122] In step S51, the acquisition unit 11 acquires inference data. Then, in step S52, the inference unit 16 uses a correction model from the acquired inference data to infer and output a model correction value and a correction time zone. Then, in step S53, the control means 10 calculates a correction temperature based on the output model correction value and correction time zone. At this time, the correction unit 12 may determine whether or not to calculate a correction temperature at the current time based on the correction time zone. Then, in step S54, the control means 10 controls each device of the air conditioning system 1 using the calculated correction temperature. Then, the operation of the flowchart ends.

[0123] If the correction model is a model for inferring only the model correction value, in step S53, the control means 10 calculates the correction temperature by adding the output model correction value to the first temperature.

[0124] If the correction model is a model for inferring only the correction time period, in step S53, the control means 10 waits until the time corresponding to the output correction time period arrives. When the time corresponding to the correction time period arrives, the control means 10 calculates the corrected temperature by adding the correction value calculated by the correction unit 12 to the first temperature.

[0125] The time progression of the first temperature, second temperature, and correction value controlled in this manner may be newly accumulated in the control means 10 as historical information about the building 90. The historical information also includes the relationship between the first temperature and second temperature, which have changed due to the influence of solar radiation on that day, and the correction value. By performing supervised learning using the historical information, a correction temperature that is more suitable for the users of the building 90 can be calculated.

[0126] According to the third embodiment described above, the air conditioning system 1 further includes a learning device 30, which is a learning means. The learning device 30 learns the trends of correction values ​​calculated in the past. The correction values ​​calculated in the past reflect the temperature influence of daily solar radiation. Therefore, by using a correction model, the air conditioning system 1 can calculate a correction value that takes into account the influence of solar radiation with less calculation effort than if calculations were performed using other correction information. Furthermore, the air conditioning system 1 can calculate a correction value that more accurately reflects the influence of solar radiation than if the correction unit 12 were to use the first temperature and the second temperature. As a result, the air conditioning system 1 and the learning device 30 can improve user comfort.

[0127] As a first variation of the learning method, the correction model may be a model for inferring at least one of the model correction value and the correction time zone using not only the first temperature and the second temperature but also weather information including information about solar radiation. The information about solar radiation includes at least one of information about weather such as clear skies, information about the amount of ultraviolet rays, and information about the amount of solar radiation. In this case, the learning data further includes a time transition of the weather information in association with the time transition. The model generation unit 32 generates the correction model based on such learning data.

[0128] The acquisition unit 11 further acquires weather information as data for inference. The inference unit 16 uses the correction model to infer at least one of the model correction value and the correction time zone from the weather information including information on the first temperature, the second temperature, and solar radiation.

[0129] According to the first modified example described above, at least one of the model correction value and the correction time period is inferred from weather information that further includes information about solar radiation. The correction temperature is a temperature that reflects the influence of solar radiation in the first space 91. Therefore, it is possible to calculate a correction temperature that is closer to the actual temperature at point B, i.e., it is possible to improve the estimation accuracy of the correction temperature.

[0130] As a second variation of the learning method, the correction model may be a model for inferring at least one of the model correction value and the correction time zone using only weather information including information on solar radiation, rather than the first and second temperatures. In this case, the learning data includes a time transition of the weather information and a time transition of the correction value, in association with each other. The model generation unit 32 generates the correction model based on such learning data.

[0131] The acquisition unit 11 acquires weather information as data for inference. The inference unit 16 uses the correction model to infer at least one of a model correction value and a correction time period from the weather information including information on solar radiation.

[0132] According to the second modified example described above, at least one of the model correction value and the correction time period is inferred from only weather information including information about solar radiation. The correction temperature is a temperature that reflects the influence of solar radiation in the first space 91. Therefore, with less information, a correction temperature that is closer to the actual temperature at point B can be calculated, i.e., the estimation accuracy of the correction temperature can be improved.

[0133] Next, a third modified example of learning will be described with reference to FIG. FIG. 19 is a schematic diagram of a building to which an air-conditioning system according to a third modification of the third embodiment is applied.

[0134] In the third modified example of learning, the air conditioning system 1 further includes a third measuring means 40. The third measuring means 40 is provided inside the second space 92. The third measuring means 40 is a temperature sensor that measures a third temperature inside the second space 92.

[0135] In a third modification, the correction model may be a model for inferring at least one of the model correction value and the correction time period using not only the first temperature and the second temperature but also a third temperature. In this case, the learning data further includes a time transition of the third temperature in association with the model correction value and the correction time period. The model generation unit 32 generates the correction model based on such learning data.

[0136] The acquisition unit 11 further acquires a third temperature as inference data from the third measurement means 40. The inference unit 16 uses the correction model to infer at least one of a model correction value and a correction time period from the first temperature, the second temperature, and the third temperature.

[0137] According to the third modified example described above, at least one of the model correction value and the correction time period is further inferred from the third temperature. The third temperature is a temperature that can change when the air blowing means 3 blows air from the first space 91 to the second space 92. Therefore, the third temperature is a temperature that reflects the temperature of point B in the first space 91. This makes it possible to calculate a correction temperature that is closer to the actual temperature at point B, i.e., improve the estimation accuracy of the correction temperature.

[0138] The second space 92 may or may not be provided with a lighting means for taking in natural light.

[0139] The first space 91 and the second space 92 may or may not be adjacent to each other. For example, another space such as a hallway may be interposed between the first space 91 and the second space 92. The first space 91 and the second space 92 may or may not be spatially connected to each other except for the air passage. Here, the "connected" state means a state in which air can move between the two spaces due to an undercut in a door or the like.

[0140] Next, an example of hardware constituting a control device, which is the control means 10, will be described with reference to FIG. FIG. 20 is a hardware configuration diagram of the control device of the air conditioning system according to the first to third embodiments.

[0141] Each function of the control device may be realized by a processing circuit, for example, including at least one processor 100a and at least one memory 100b, and at least one dedicated hardware 200.

[0142] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the control device is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in the at least one memory 100b. The at least one processor 100a realizes each function of the control device by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also called a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD.

[0143] When the processing circuit includes at least one dedicated hardware 200, the processing circuit may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the control device may be implemented by a processing circuit. For example, each function of the control device may be implemented collectively by a processing circuit.

[0144] Some of the functions of the control device may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. For example, the function of airflow control unit 14 may be realized by a processing circuit as dedicated hardware 200, and functions other than the function of airflow control unit 14 may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0145] Thus, the processing circuitry implements the functions of the controller in hardware 200, software, firmware, or a combination thereof.

[0146] At least some of the functions of the control device may be realized on a cloud server. In this case, the processing circuit is composed of multiple partial circuits. The multiple partial processing circuits are provided in each of the multiple devices that make up the cloud server. The multiple devices that make up the cloud server may each be provided in a different building. In this case, the functions of the control device that are realized on the cloud server are involved in controlling the air conditioning means 2, etc. by communicating with the air conditioning means 2, etc. via a network.
