The control unit 62 executes a program 631 stored in the storage unit 63 to control measurement by the measurement unit 61. The control unit 62 causes the storage unit 63 to store measurement data 632 that is the result of measurement by the measurement unit 61.

Next, when the position of the heat source in the air-conditioned space is changed, the operation of the air-conditioning control system 100 until the air-conditioned space is brought into a desired air-conditioned state after the position of the heat source is changed will be described. FIG. 2 is a flowchart showing the operation of the air conditioning control system 100 according to the first embodiment.

In the air conditioner 50, the air conditioning control unit 14 of the controller 10 controls the operation of the air conditioner 50, specifically the operation of the indoor unit 20 and the outdoor unit 30, under the first air conditioning condition, and performs air conditioning control of the space to be air conditioned. (Step S101). The first air-conditioning condition is an air-conditioning condition for bringing the entire air-conditioned space into a desired air-conditioned state when the air-conditioned space has the first heat source distribution. The desired air conditioning state is, for example, a target temperature specified by the user via the remote controller 40. The first heat source distribution is a heat source distribution before the position of the heat source is changed in the air-conditioned space.

FIG. 3 is a diagram illustrating an example of a first heat source distribution in an air-conditioned space that is subject to air-conditioning control by the air-conditioning control system 100 according to the first embodiment. In the example of the first heat source distribution shown in FIG. 3, if there is a heat source in area A of the air-conditioned space and the air conditioning control system 100 is not performing air conditioning control, the temperature in area A is higher than the surrounding area. It shows. The air conditioning control unit 14 of the controller 10 lowers the set temperature, increases the air volume, or changes the wind direction to the area A so that the area A of the air-conditioned space reaches the target temperature. Air conditioning control is performed according to the first air conditioning condition, which is an air conditioning condition such as concentration.

FIG. 4 is a diagram showing an example of the first temperature distribution when the air conditioning control system 100 according to the first embodiment performs air conditioning control under the first air conditioning condition when the air conditioning target space has the first heat source distribution. be. The air conditioning control unit 14 of the controller 10 controls the entire air-conditioned space to a desired temperature as shown in FIG. 4 by performing air conditioning control under the first air conditioning condition for the first heat source distribution shown in FIG. A target temperature, that is, a constant temperature can be set.

The measuring device 60 measures the temperature distribution of the air-conditioned space that is being air-conditioned under the first air-conditioning condition by the air-conditioning control unit 14 of the controller 10 (step S102). The measuring device 60 may measure the temperature distribution of the air-conditioned space when receiving a measurement instruction from the controller 10, or may measure the temperature distribution of the air-conditioned space when receiving a notification from the controller 10 that air conditioning control has started. The temperature distribution may be measured periodically, or the temperature distribution in the air-conditioned space may be measured periodically without depending on instructions from the controller 10. The measuring device 60 transmits the temperature distribution obtained as a result of the measurement to the controller 10 as measurement data 632.

Upon receiving the measurement data 632 from the measuring device 60, the communication unit 11 of the controller 10 stores the temperature distribution, which is the received measurement data 632, in the storage unit 12 as history information 122 (step S103). At this time, in the controller 10, the air conditioning control unit 14, in cooperation with the communication unit 11, associates the first air conditioning condition with the temperature distribution, which is the measurement data 632 acquired from the measuring device 60, as the history information 122. The information is stored in the storage unit 12. That is, the storage unit 12 stores history information 122 including the first temperature distribution and the first air conditioning condition. The first temperature distribution is the temperature distribution of the air-conditioned space measured by the measuring device 60 while the air-conditioning control unit 14 is controlling the air-conditioning under the first air-conditioning condition when the air-conditioning space has the first heat source distribution. . The first air-conditioning condition is an air-conditioning condition under which the air-conditioning control unit 14 brings the air-conditioned space into a desired air-conditioned state when the air-conditioned space has the first heat source distribution.

The calculation unit 13 of the controller 10 determines whether the heat source distribution has been changed in the air-conditioned space (step S104). Specifically, the calculation unit 13 compares the latest temperature distribution with the previously acquired temperature distribution, and determines whether the heat source distribution has changed in the air-conditioned space depending on whether the temperature distribution in the air-conditioned space has changed. Determine whether or not. When the calculation unit 13 determines that the heat source distribution has not been changed in the air-conditioned space (step S104: No), the air conditioning control system 100 returns to step S101 and repeats the above operation.

If it is determined that the heat source distribution in the air-conditioned space has been changed (step S104: Yes), the calculation unit 13 sets the previously acquired temperature distribution as the first temperature distribution, and sets the latest temperature distribution as the first temperature distribution in the air-conditioned space. The difference between the first temperature distribution and the second temperature distribution is calculated as the second temperature distribution of the air-conditioned space in the state where the heat source distribution has been changed to the second heat source distribution (step S105). The calculation unit 13 uses the difference between the first temperature distribution and the second temperature distribution to determine a second air conditioning condition that brings the air conditioned space into a desired air conditioning state when the air conditioned space has the second heat source distribution. is calculated (step S106).

FIG. 5 is a diagram illustrating an example of the second heat source distribution in the air-conditioned space that is subject to air-conditioning control by the air-conditioning control system 100 according to the first embodiment. In the example of the second heat source distribution shown in FIG. 5, if there is a heat source in region B of the air-conditioned space and the air conditioning control system 100 is not performing air conditioning control, the temperature in region B is higher than that in the surrounding region. It shows.

FIG. 6 is a diagram showing an example of a second temperature distribution when the air conditioning control system 100 according to the first embodiment performs air conditioning control under the first air conditioning condition in a state where the air conditioning target space has the second heat source distribution. be. The first air conditioning condition is an air conditioning condition for making the air-conditioned space have the first temperature distribution shown in FIG. 4 with respect to the first heat source distribution shown in FIG. 3. Therefore, even if the air-conditioning control unit 14 of the controller 10 performs air-conditioning control under the first air-conditioning condition when the air-conditioned space has the second heat source distribution, the air-conditioning control unit 14 controls the air-conditioned space to the first temperature as shown in FIG. It cannot be made into a state of distribution. Even if the air conditioning control unit 14 of the controller 10 performs air conditioning control under the first air conditioning condition when the air conditioned space has the second heat source distribution, the air conditioned space will be in the second temperature distribution state shown in FIG. .

The second temperature distribution shown in FIG. 6 shows that region B has a higher temperature than the surrounding region, and region A has a lower temperature than the surrounding region. This is because, in the first heat source distribution, there was originally a heat source in area A, so the first air conditioning conditions are such that the temperature in area A is lowered than in other areas. This is also because the first air conditioning conditions for area B were similar to those for areas other than area A, and therefore the air conditioning conditions were not such that the temperature would be lower than for the other areas.

Therefore, the calculation unit 13 corrects the first air conditioning condition using the difference between the first temperature distribution and the second temperature distribution, raises the temperature of area A to the same temperature as the surrounding area, and , the second air conditioning condition is calculated so as to lower the temperature of region B to the same temperature as the surrounding region. FIG. 7 is a diagram illustrating an example of temperature distribution when the air conditioning control system 100 according to the first embodiment performs air conditioning control under the second air conditioning condition when the air conditioning target space has the second heat source distribution. The air conditioning control unit 14 of the controller 10 controls the entire air-conditioned space to a desired temperature as shown in FIG. 7 by performing air conditioning control under the second air conditioning condition for the second heat source distribution shown in FIG. A target temperature, that is, a constant temperature can be set.

In this way, the calculation unit 13 uses the heat source information indicating the position of the heat source and the amount of heat of the heat source when the air conditioned space has the second heat source distribution, and the history information 122 to determine whether the air conditioned space has the first heat source distribution. When the distribution is changed from the distribution to the second heat source distribution, a second air conditioning condition is calculated to bring the air conditioned space into a desired air conditioning state when the air conditioned space has the second heat source distribution. In the present embodiment, the storage unit 12 stores the second data of the air-conditioned space measured by the measuring device 60 during air-conditioning control of the air-conditioned space under the first air conditioning condition when the air-conditioned space has the second heat source distribution. temperature distribution is stored as history information 122. The calculation unit 13 uses the second temperature distribution as heat source information to calculate the difference between the first temperature distribution and the second temperature distribution. The calculation unit 13 corrects the first air conditioning condition using the difference and calculates the second air conditioning condition.

The calculation unit 13 calculates the start timing at which the air conditioning control unit 14 starts air conditioning control of the air conditioning target space under the second air conditioning condition (step S107). For example, if the layout of a certain store is changed after business hours, the air conditioner 50 may start air conditioning control under the second air conditioning condition before the business hours start the next day. Therefore, the calculation unit 13 calculates the start timing as necessary. Note that the calculation unit 13 may omit calculation of the start timing in a case where the air conditioning control unit 14 continues to perform air conditioning control. Further, the calculation unit 13 may set the start timing to “immediately” so that the air conditioning control unit 14 can immediately start air conditioning control under the second air conditioning condition.

The air conditioning control unit 14 of the controller 10 controls the operation of the air conditioning equipment 50, specifically the operation of the indoor unit 20 and the outdoor unit 30, under the second air conditioning condition calculated by the calculation unit 13, and controls the air conditioning of the space to be air conditioned. (Step S108). If the start timing has been calculated by the calculation unit 13, the air conditioning control unit 14 performs air conditioning control of the air conditioning target space under the second air conditioning condition in accordance with the start timing. Thereafter, the air conditioning control system 100 sets the second air conditioning condition calculated by the calculation unit 13 as the first air conditioning condition, and sets the second heat source distribution with the changed position of the heat source as the first heat source distribution. (Step S109). The air conditioning control system 100 returns to step S102 and repeats the above operation.

Next, the hardware configuration of the controller 10 will be explained. FIG. 8 is a diagram illustrating an example of a processing circuit included in the controller 10 according to the first embodiment. In the controller 10, the communication unit 11 is an interface that communicates with the measuring device 60. The storage unit 12 is a memory. The calculation section 13 and the air conditioning control section 14 are realized by a processing circuit. The processing circuit is, for example, a processor 91 that executes a program stored in the memory 92, and a memory 92.

When the processing circuit is composed of the processor 91 and the memory 92, each function of the processing circuit is realized by software, firmware, or a combination of software and firmware. Software or firmware is written as a program and stored in memory 92. In the processing circuit, each function is realized by the processor 91 reading and executing a program stored in the memory 92. It can also be said that these programs cause the computer to execute the procedures and methods of the controller 10.

Here, the processor 91 may be a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, a DSP (Digital Signal Processor), or the like. The memory 92 also includes nonvolatile or volatile memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ROM), and EEPROM (registered trademark) (Electrically EPROM). This includes semiconductor memory, magnetic disks, flexible disks, optical disks, compact disks, mini disks, and DVDs (Digital Versatile Discs).

The processing circuit may be dedicated hardware. When the processing circuit is composed of dedicated hardware, the processing circuit may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate). Array), or a combination of these. Each function of the controller 10 may be realized by a processing circuit for each function, or each function may be realized by a processing circuit collectively.

Note that some of the functions of the controller 10 may be realized by dedicated hardware, and some may be realized by software or firmware. In this way, the processing circuit can implement each of the above-mentioned functions using dedicated hardware, software, firmware, or a combination thereof.

The same applies to the hardware configuration of the measuring device 60. In the measuring device 60, the measuring section 61 is a sensor capable of measuring temperature distribution as described above. The storage unit 63 is a memory. The communication unit 64 is an interface that communicates with the controller 10. The control unit 62 is realized by a processing circuit. The processing circuit may include a processor 91 and a memory 92, or may be dedicated hardware.

As described above, according to the present embodiment, when the position of the heat source in the air-conditioned space is changed, the controller 10 of the air-conditioning control system 100 is configured to perform the first heat source distribution when the air-conditioned space has the first heat source distribution. Difference between the first temperature distribution when air conditioning control is performed under the air conditioning conditions and the second temperature distribution when air conditioning control is performed under the first air conditioning conditions when the air conditioning target space has the second heat source distribution. Calculate. The calculation unit 13 corrects the first air conditioning condition using the difference, and calculates a second air conditioning condition for bringing the air conditioning target space into a desired air conditioning state when the air conditioning target space has a second heat source distribution. . Thereby, the controller 10 can suppress the time required to bring the air-conditioned space into a desired air-conditioned state when the position of the heat source is changed in the air-conditioned space.

The space to be air-conditioned should not have a simple shape as shown in Figures 3 to 7, but should have a shape that affects the flow of air during air-conditioning control, such as an L-shape or large pillars in the room. It is also assumed that It is also assumed that fixtures and other fixtures installed in the air-conditioned space have shapes that affect the flow of air during air-conditioning control. In such a case, the air conditioning control system 100 increases the air volume or concentrates the air direction in advance in areas where the airflow from the indoor unit 20 is difficult to reach, depending on the characteristics of the space to be air conditioned. It is necessary to perform controls such as making the temperature lower than the target temperature, or in the case of heating, making the set temperature higher than the target temperature. A general air conditioning system as described in Patent Document 1 performs air conditioning control according to the temperature distribution each time the temperature distribution of the air-conditioned space is measured or estimated, and further controls the air-conditioning according to the characteristics of the air-conditioned space. Therefore, it is necessary to modify the contents of the air conditioning control. Therefore, it takes time to bring the air-conditioned space into the desired air-conditioned state.

In contrast, the air conditioning control system 100 of the present embodiment utilizes the first air conditioning condition that can control the air conditioned space to a desired air conditioning state when the position of the heat source in the air conditioned space has the first heat source distribution. do. The first air conditioning condition is an air conditioning condition that reflects the characteristics of the space to be air conditioned. Therefore, in the air conditioning control system 100, the controller 10 corrects the first air conditioning condition using the difference between the first temperature distribution and the second temperature distribution. The air conditioning conditions of No. 2 can be easily calculated.

In addition, in the air conditioning control system 100, the controller 10 adjusts the air conditioning conditions to bring the air conditioned space into a desired air conditioning state while reflecting the characteristics of the air conditioned space as the heat source distribution changes in the air conditioned space. There are many processes to correct. Therefore, by learning the correction details, the controller 10 can shorten the calculation time when calculating new air conditioning conditions.

Further, in this embodiment, the air conditioning control system 100 has been described for controlling the entire air-conditioned space to the same temperature, but this is only an example, and the present invention is not limited to this. When the air conditioning control system 100 includes a plurality of remote controllers 40, the air conditioning control system 100 controls the air conditioning so that the temperature of a certain area of the air-conditioned space is higher than the surrounding area, and controls the air conditioning so that the temperature of a certain area of the air-conditioned space is higher than that of the surrounding area, according to the preference of the user who operates each remote controller 40. Air conditioning may be controlled so that the temperature of the area is lower than that of surrounding areas. Further, the air conditioning control system 100 may set the wind direction so that the wind hits one user, and the wind direction so that the wind does not hit another user, depending on the preference of the user who operates each remote controller 40.

Embodiment 2.
In Embodiment 2, a case will be described in which, when the position of the heat source is changed in the air-conditioned space, the controller 10 acquires information about the position of the heat source and the amount of heat from the user.

In the second embodiment, the configuration of air conditioning control system 100 is similar to the configuration in the first embodiment shown in FIG. The operation of the air conditioning control system 100, when the position of the heat source is changed in the air-conditioned space, will be described until the air-conditioned space is brought into a desired air-conditioned state after the position of the heat source is changed. FIG. 9 is a flowchart showing the operation of air conditioning control system 100 according to the second embodiment. In the flowchart shown in FIG. 9, the operations from step S101 to step S103 are the same as the operations from step S101 to step S103 in the flowchart in the first embodiment shown in FIG.

The calculation unit 13 of the controller 10 determines whether heat source information has been set by the user via the remote controller 40 (step S111). The heat source information is information on the second heat source distribution when the position of the heat source in the air-conditioned space has been changed or is scheduled to be changed. For example, if the user wants to set heat source information in the controller 10, the user operates a predetermined switch or the like on the remote controller 40 to notify the controller 10 that the heat source information is scheduled to be set. The calculation unit 13 of the controller 10 can determine whether the heat source information has been set by the user based on the notification from the remote controller 40. When the calculation unit 13 determines that the heat source information is not set (step S111: No), the air conditioning control system 100 returns to step S101 and repeats the above operation.

If it is determined that the heat source information has been set (step S111: Yes), the calculation unit 13 receives the heat source information setting from the user via the remote controller 40, and acquires the heat source information (step S112). The calculation unit 13 uses the history information 122 and the heat source information to perform a second process that brings the air-conditioned space into a desired air-conditioned state when the air-conditioned space is changed from the first heat source distribution to the second heat source distribution. Air conditioning conditions are calculated (step S113). The calculation unit 13 modifies the first air conditioning condition using the heat source information specified by the user, raises the temperature of area A to the same temperature as the surrounding area, and raises the temperature of area B to the same temperature as the surrounding area. The second air conditioning condition is calculated so as to lower the temperature to the same level as the temperature. The calculation unit 13 calculates the start timing at which the air conditioning control unit 14 starts air conditioning control under the second air conditioning condition, as necessary (step S114). In the flowchart shown in FIG. 9, the operations in step S108 and step S109 are similar to the operations in step S108 and step S109 in the flowchart in the first embodiment shown in FIG.

As described above, according to the present embodiment, the controller 10 of the air conditioning control system 100 calculates the second air conditioning condition using the heat source information specified by the user. Even in this case, air conditioning control system 100 can obtain the same effects as in the first embodiment.

In the present embodiment, the calculation unit 13 of the controller 10 determines whether or not the heat source information is set by the user (step S111), and then receives the heat source information setting from the user and acquires the heat source information. (Step S112), but is not limited to this. The user may directly set the heat source information without notifying the controller 10 that the heat source information is scheduled to be set. In this case, the calculation unit 13 of the controller 10 determines whether the heat source information has actually been set by the user via the remote controller 40. Thereby, the calculation unit 13 of the controller 10 can reduce the effort required to acquire heat source information.

Embodiment 3.
