The present invention relates to a control device, an air conditioning system, an air conditioning control method, and a program.

In recent years, zero energy house (ZEH) that uses energy efficiently has attracted attention. In relation to this, a so-called HEMS (Home Energy Management System) that manages electric power used in general households has become widespread. In HEMS, in addition to an air conditioner and a ventilation device, a technology for automatically controlling a solar radiation shielding device such as an electric blind, an electric shutter, an electric awning, or an electric curtain is also known.

A technique (for example, Patent Document 1) for reducing an air conditioning load such as an air conditioner and a ventilator using such a solar shading device has been proposed.

In Patent Document 1, in summer, in order to reduce energy consumption in the cooling operation of an air conditioner, introduction of sunlight into a room is restricted by adjusting the angle of a slat of a solar radiation shielding device. On the other hand, in winter, in order to reduce the energy consumption due to the heating operation of the air conditioner, the introduction of sunlight into the room is promoted by adjusting the angle of the slats.

The temperature adjusting unit 204 is an example of a temperature adjusting unit provided in the control device according to the present invention. The temperature adjustment unit 204 adjusts the air temperature of the room A by controlling the blower 7 and the solar shading device 8 based on the air temperature of the room A, the air temperature of the room B, and the amount of solar radiation of the room A.

FIG. 5 is a flowchart showing a procedure of air conditioning control processing executed by the temperature adjustment unit 204. The temperature adjustment unit 204 executes the air conditioning control process periodically (for example, every minute). The content of the air conditioning control process described below along the flowchart of FIG. 5 mainly corresponds to the summer when the outside air temperature is high.

In step S101, the temperature adjustment unit 204 determines whether or not the air temperature in the room A exceeds the set temperature (that is, the target temperature) of the air conditioner 5. When the air temperature in the room A does not exceed the set temperature (step S101; NO), the temperature adjustment unit 204 ends the air conditioning control process in this cycle. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

On the other hand, when the air temperature in the room A exceeds the set temperature (step S101; YES), the temperature adjustment unit 204 has exceeded the predetermined threshold value for the amount of solar radiation in the room A acquired by the solar radiation amount acquisition unit 203. It is determined whether or not there is (step S102). This threshold value is determined based on, for example, an energy amount that can increase the air temperature in the room A by 1 ° C.

If the amount of solar radiation in the room A does not exceed the threshold (step S102; NO), the temperature adjustment unit 204 ends the air conditioning control process in this cycle. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

When the amount of solar radiation in the room A exceeds the threshold (step S102; YES), the temperature adjustment unit 204 instructs the solar radiation shielding device 8 to perform a closing operation (step S103). Specifically, the temperature adjustment unit 204 transmits shielding control information indicating an instruction to change the blind angle to 0 ° to the solar shading device 8. If the blind angle of the solar radiation shielding device 8 is already 0 °, the temperature adjustment unit 204 may not transmit the shielding control information to the solar radiation shielding device 8.

The temperature adjustment unit 204 determines whether or not the air temperature in the room B is lower than the air temperature in the room A (step S104). If the air temperature in the room B is not lower than the air temperature in the room A, that is, if the air temperature in the room B is equal to or higher than the air temperature in the room A (step S104; NO), the temperature adjustment unit 204 performs air conditioning in this cycle. The control process ends. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

On the other hand, when the air temperature in the room B is lower than the air temperature in the room A (step S104; YES), the temperature adjustment unit 204 instructs the blower 7 to start driving (step S105). Specifically, the temperature adjustment unit 204 transmits drive control information indicating a drive start instruction to the blower 7. When the blower 7 is driven, that is, starts to rotate, the air in the room B is sucked into the vent hole 90 and flows into the room A. In this case, the warm air in the room A corresponding to the amount that has flowed in flows out to the outside through a ventilation port provided in the room A or a gap between doors. In addition, when the air blower 7 is already driving, the temperature adjustment unit 204 may not transmit the drive control information to the air blower 7. Thereafter, the temperature adjustment unit 204 ends the air conditioning control process in this cycle.

Although not shown in the flowchart of FIG. 5, the temperature adjustment unit 204 instructs the blower 7 to stop driving when the air temperature in the room B becomes equal to or higher than the air temperature in the room A after the drive start instruction to the blower 7. To do. Thereby, the inflow of air from the room B to the room A is stopped.

As described above, according to the air conditioning system 1 of the first embodiment, when the air temperature of the room A, which is the air conditioning target area, is higher than the set temperature and the influence of the solar radiation on the air temperature of the room A is large, Shield solar radiation entering room B. When the air temperature in the room B decreases and becomes lower than the room A, the air in the room B is sent to the room A. Thereby, the raise of the air temperature of the room A can be suppressed. As a result, the load during the cooling operation of the air conditioner 5 in the room A can be reduced, and an energy reduction effect can be obtained.

Further, since the above-described temperature adjustment is realized by controlling the solar shading device 8 installed in the room B different from the air-conditioned room A, the electric blind similar to the solar shading device 8 in the room A is used. Even if it is a case where etc. are not installed, the raise of the air temperature of the room A can be suppressed.

Furthermore, even if an electric blind or the like similar to the solar shading device 8 is installed in the room A, the electric blind or the like is not controlled for the temperature adjustment. In other words, the closing operation is not performed even when the user blindly puts the electric blind or the like in order to positively capture sunlight and actively take in sunlight. For this reason, the lighting environment of the room A is maintained, and the user's comfort is not impaired.

Note that, as described above, the air conditioning control process described above is executed particularly in the summer (that is, when the air conditioner 5 performs the air conditioning operation), and thus a special effect is expected as described above. You can do it. However, in addition to solar radiation, internal heat generated in the room A (due to a user or a heat generating device) may cause the winter (that is, the time when the air conditioner 5 is air-conditioned by the heating operation of the air conditioner 5) or the intermediate period (summer). Even during winter, the air temperature in the room A may exceed the set temperature. In such a case, by executing the air conditioning control process described above, it is possible to suppress the rise of the room A while suppressing the load on the air conditioner 5.

(Modification 1)
As a first modification of the first embodiment, an air conditioning control process when it is desired to increase the air temperature in the room A in winter or the like will be described.

FIG. 6 is a flowchart illustrating a procedure of air conditioning control processing executed by the temperature adjustment unit 204 of the control device 2 according to the first modification of the first embodiment. The temperature adjustment unit 204 executes this air conditioning control process periodically (for example, every minute).

In step S201, the temperature adjustment unit 204 determines whether the air temperature in the room A is lower than the set temperature (that is, the target temperature) of the air conditioner 5. If the air temperature in the room A is not lower than the set temperature, that is, if the air temperature in the room A is equal to or higher than the set temperature (step S201; NO), the temperature adjustment unit 204 ends the air conditioning control process in this cycle. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

On the other hand, when the air temperature in the room A is lower than the set temperature (step S201; YES), the temperature adjustment unit 204 determines whether the solar radiation amount of the room A acquired by the solar radiation amount acquisition unit 203 exceeds a predetermined threshold value. Is determined (step S202). As described above, this threshold is determined based on the amount of energy that can increase the air temperature in the room A by 1 ° C., for example.

If the amount of solar radiation in the room A does not exceed the threshold (step S202; NO), the temperature adjustment unit 204 ends the air conditioning control process in this cycle. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

If the amount of solar radiation in the room A exceeds the threshold value (step S202; YES), the temperature adjustment unit 204 instructs the solar radiation shielding device 8 to open (step S203). Specifically, the temperature adjustment unit 204 transmits shielding control information indicating an instruction to change the blind angle to 90 ° to the solar shading device 8. If the blind angle of the solar radiation shielding device 8 is already 90 °, the temperature adjustment unit 204 may not transmit the shielding control information to the solar radiation shielding device 8.

The temperature adjustment unit 204 determines whether or not the air temperature in the room B is higher than the air temperature in the room A (step S204). When the air temperature in the room B is not higher than the air temperature in the room A, that is, the air temperature in the room B is equal to or lower than the air temperature in the room A (step S204; NO), the temperature adjustment unit 204 performs air conditioning in this cycle. The control process ends. In this case, if the air conditioner 5 in the room A is in operation, the air conditioner 5 continues to air-condition the room A.

On the other hand, when the air temperature in the room B is higher than the air temperature in the room A (step S204; YES), the temperature adjusting unit 204 instructs the blower 7 to start driving (step S205). Specifically, the temperature adjustment unit 204 transmits drive control information indicating a drive start instruction to the blower 7. When the blower 7 is driven, that is, starts to rotate, the air in the room B is sucked into the vent hole 90 and flows into the room A. In this case, the cold air in the room A corresponding to the inflow is discharged to the outside through a ventilation port provided in the room A or a gap between doors. In addition, when the air blower 7 is already driving, the temperature adjustment unit 204 may not transmit the drive control information to the air blower 7. Thereafter, the temperature adjustment unit 204 ends the air conditioning control process in this cycle.

Although not shown in the flowchart of FIG. 6, the temperature adjustment unit 204 instructs the blower 7 to stop driving when the air temperature in the room B becomes equal to or lower than the air temperature in the room A after the drive start instruction to the blower 7. To do. Thereby, the inflow of air from the room B to the room A is stopped. In synchronism with this, the temperature adjusting unit 204 instructs the solar shading device 8 to close.

As described above, according to the air conditioning system 1 of the first modification of the first embodiment, the air temperature in the room A that is the air conditioning target area is lower than the set temperature, and the influence of the solar radiation on the air temperature in the room A is affected. If it is larger, the solar radiation is taken into the room B. When the air temperature in the room B rises and becomes higher than the room A, the air in the room B is sent to the room A. Thereby, the fall of the air temperature of the room A can be suppressed. As a result, the load during the heating operation of the air conditioner 5 in the room A can be reduced, and an energy reduction effect can be obtained.

Further, since the above-described temperature adjustment is realized by controlling the solar shading device 8 installed in the room B different from the air-conditioned room A, the electric blind similar to the solar shading device 8 in the room A is used. Even if it is a case where etc. are not installed, the fall of the air temperature of the room A can be suppressed.

Furthermore, even if an electric blind or the like similar to the solar shading device 8 is installed in the room A, the electric blind or the like is not controlled for the temperature adjustment. That is, even when the user places importance on protecting the privacy and dares to make the electric blinds fully closed, the opening operation is not performed and the user is not inconvenienced or uncomfortable. .

(Modification 2)
The control device 2 accepts a determination as to whether or not to approve the operation of the solar shading device 8 from the user before instructing the solar shading device 8 to open or close, and when the user approves, You may make it instruct | indicate an opening operation or a closing operation with respect to the solar radiation shielding apparatus 8. FIG. In this case, the control device 2 displays an approval reception screen as shown in FIGS. 7 and 8 on the operation terminal 3 or a smartphone or the like possessed by the user. When the “Yes” button on the approval reception screen is pressed by the user, the control device 2 determines that the user has approved, and instructs the solar shading device 8 to open or close.

This makes it possible to avoid a situation in which inconvenience occurs when the solar shading device 8 is automatically controlled, such as when there is a person in the room B.

(Modification 3)
When the air temperature in the room A is higher or lower than the set temperature, the control device 2 may notify the user that the effect of energy reduction can be obtained by shielding or capturing the solar radiation in the room A. In this case, the control device 2 displays an advice screen as shown in FIGS. 9 and 10 on the operation terminal 3 or a smartphone or the like possessed by the user.

In this way, the user can be conscious of energy reduction, and the user can determine whether or not to block or capture solar radiation. For this reason, significant information regarding energy reduction can be given to the user, and when the user agrees and executes, the air temperature in the room A can be adjusted more efficiently.

(Modification 4)
When a solar shading device such as an external electric blind similar to the solar shading device 8 is installed in the room A and the solar shading device can be controlled by the control device 2, the control device 2 obtains approval from the user. On the condition, you may make it instruct | indicate an opening operation | movement or a closing operation | movement with respect to this solar radiation shielding apparatus. Also in this case, the control apparatus 2 should just display the approval reception screen similar to FIG.7 and FIG.8 on the operation terminal 3 or the smart phone etc. which a user possesses.

Even in this way, it is possible to prevent the operation of shielding or taking in sunlight against the user's will, and if the user approves, it will block or take in the sunlight in the room A that is the air-conditioning target area. It becomes possible to adjust the air temperature of the room A efficiently, and energy can be further reduced.

(Modification 5)
The control device 2 further includes a presence / absence determining unit (an example of a presence / absence determining unit) that determines the presence / absence of a person in the room A that is the air-conditioning target area, and the temperature adjustment unit 204 is provided on the condition that there is a person in the room A. You may perform the above-mentioned air-conditioning control processing (refer FIG. 5 or FIG. 6). For example, the presence / absence determining unit may determine that there is a person when the air conditioner 5 in the room A is operating. Alternatively, the presence / absence of a person in the room A may be determined based on the occupancy schedule information registered in advance in the control device 2 by the user. Alternatively, a human sensor may be installed in the room A and connected to the control device 2 via the wireless network described above so as to be communicable. In this case, the presence / absence determining unit determines the presence / absence of a person according to the detection result of the human sensor.

(Modification 6)
In the above-described embodiment and the first modification of the embodiment, the air in the room B is caused to flow into the room A by the blower 7, and further, the air in the room A is caused to flow into the room B, that is, the air in the room A. And the air in the room B may be circulated.

The room temperature transition of the room A is an example of a first temperature transition in the present invention, and the room temperature transition of the room B is an example of a second temperature transition in the present invention. For example, the room temperature prediction unit 208 predicts the change in the room temperature of the room A from the change in the solar radiation amount predicted by the solar radiation amount prediction unit 206 and the history of the outside temperature on the previous day. In addition, the room temperature prediction unit 208 predicts a change in the room temperature of the room B based on, for example, the change in the solar radiation amount predicted by the solar radiation amount prediction unit 206, the history of the outside air temperature on the previous day, and the shielding schedule.

Thus, according to the present embodiment, the control device 2 predicts the change in the amount of solar radiation in the room A, the change in the air temperature in the room A, and the change in the air temperature in the room B, and these prediction results. The blower 7 and the solar shading device 8 are controlled according to a schedule created in advance based on the above. For this reason, the cooling load of the air conditioner 5 in the room A can be efficiently reduced.

Create an occlusion schedule. In addition, when it is predicted that the air temperature in the room A will be lower than both the set temperature and the air temperature in the room B at a certain time, the air blowing schedule creation unit 209 may be a predetermined time before the time. By scheduling so as to drive the blower 7, a blow schedule is created.

(Modification 2)
The blow schedule creation unit 209 may create a blow schedule in consideration of the user's occupancy schedule in the room A. Specifically, in the summer season, the air blowing schedule creation unit 209 predicts that the air temperature at a certain time will be higher than both the set temperature and the air temperature in the room B on condition that the user is in the room A. In the case of being performed, the air blowing schedule is created by scheduling the air blower 7 to be driven before the predetermined time.

In the winter season, the air blowing schedule creation unit 209 predicts that the air temperature at a certain time will be lower than both the set temperature and the air temperature in the room B on condition that the user is in the room A. In this case, the air blowing schedule is created by scheduling the air blower 7 to be driven before the predetermined time.

(Modification 3)
The shielding schedule creation unit 207 sets the blind angle of the shielding device 8 to 0 ° (in the case of summer) during the above period (for example, from 6 am to 6 pm on the same day) regardless of the user's occupancy schedule in the room B. Or you may create the shielding schedule scheduled so that it may control to 90 degrees (in the case of winter).
