Thereafter, the control parameter table selection unit selects a control parameter table from the plurality of control parameter tables based on the difference between the average value of the outside air information in the past predetermined period and the outside air information on the current day. The control parameter update unit updates the value of the currently used control parameter based on the control parameter table selected by the control parameter table selection unit and the outside air information of the day.
For example, if the outside air temperature, which has remained normal during the past predetermined period, suddenly drops on the same day, the outside air temperature may be the same, but it may be felt cold. This air conditioning control system includes a plurality of control parameter tables in which outside air information and air conditioner control parameters are associated with each other. The control parameter table selection unit calculates a difference between the average value of the outside air information in the past predetermined period and the outside air information on the current day, and selects a control parameter table from the plurality of control parameter tables based on the difference. . Furthermore, the control parameter update unit updates the value of the control parameter currently used based on the control parameter table selected by the control parameter selection unit and the outside air information on that day. As a result, the air conditioner is controlled by one or more control parameters. For this reason, improvement in comfort can be expected by fine air-conditioning control that reflects changes and magnitudes of outside air information.
Note that the outside air information specifically assumes, for example, an outside air discomfort index. The outside air discomfort index is closely related to the outside air temperature, and is calculated based on the outside air temperature and other weather information. The outside air temperature here is simply the temperature of the outside air. The outside air information and the outside air temperature do not always coincide with each other, and are basically different information.

[First Embodiment]
Here, the air conditioning control system 1 according to the first embodiment of the present invention will be described with reference to the drawings. First, a description will be given assuming that the air conditioner 9a performs a heating operation in winter. The same is true in principle when the cooling operation is performed in summer.
For example, even if the temperature is the same, a midwinter day in early winter may be felt colder than a midwinter day in midwinter. This may be because the body has not yet adapted to the full-scale cold in early winter.
In addition, the temperature that has been around the normal level may suddenly drop. Even in such a case, it may be felt cold in terms of experience.
In this way, there may be a slight difference between the actual temperature and the sensory temperature. The air conditioning control system according to the present invention is intended to realize an improvement in comfort and an energy saving effect in consideration of such a situation.

FIG. 3 is one example showing the relationship between the outdoor air discomfort index and the body sensation. The outside air discomfort index is an index that can be converted from the outside air temperature and humidity, and is closely related to the outside air temperature. However, the outside air temperature here is simply the outside air temperature, and the outside air discomfort index and the outside air temperature are basically different information.
In the present invention, the term “outside air temperature” is used, which means the temperature of the outside air, for example, in relation to air conditioning technology. You can think of it as a synonym. Accordingly, in the description of the present invention, “air temperature” as a general weather term may be used in addition to “outside air temperature”, but this may be considered to have the same meaning as “outside air temperature”. Absent.
[Components of the air-conditioning control system 1 according to the first embodiment]
(Overall configuration)
As shown in FIG. 1, the air conditioning control system 1 acquires weather information via a network 6 from a weather information distribution source 5 that distributes weather information, such as a weather information site, and the weather information distribution source 5. At the same time, the remote management device 7 that generates the operation information of the air conditioner 9 a based on the acquired weather information, the building 9 in which the air conditioner 9 a is installed, and the air conditioner supplied from the remote management device 7 via the network 6. And a local control device 8 for controlling the air conditioner 9a of the building 9 via the network 6 based on the operation information of the machine 9a.

The remote management device 7 acquires weather information from the weather information distribution source 5 via the network 6. And the driving | operation information of the air conditioner 9a is produced | generated based on the acquired weather information. Note that the operation information of the air conditioner 9a specifically refers to control parameters of the air conditioner 9a described later. The operation information of the air conditioner 9 a generated by the remote management device 7 is transmitted to the local control device 8 via the network 6. The local control device 8 is connected to the air conditioner 9 a installed in the building 9 through the network 6. And based on the driving | operation information of the air conditioner 9a acquired from the remote management apparatus 7 via the network 6, the operation | movement of the air conditioner 9a installed in the building 9 is controlled. Hereinafter, the details will be described focusing on the remote management device 7.
(1) Remote Management Device The remote management device 7 includes a control parameter table 10, a control parameter table selection unit 20, a control parameter update unit 30, a control unit 40, a storage unit 45, and a communication unit 50, as shown in FIG. Is provided. The control parameter table 10 is a table in which an outside air discomfort index is associated with a control parameter of the air conditioner 9a (hereinafter simply referred to as a control parameter). The control parameter table 10 includes control parameter tables 10AS, 10AW, 10BS, and 10BW (see Tables 1 to 4 described later). The control parameter tables 10AS, 10AW, 10BS, and 10BW are stored in the storage unit 45 described later. The control parameter tables 10AS and 10BS are for summer. The control parameter tables 10AW and 10BW are for winter. The summer control parameter tables 10AS and 10BS are used when the air conditioner is operated in the cooling operation mode. The winter control parameter tables 10AW and 10BW are used when the air conditioner is operated in the heating operation mode.

Based on the difference between the average value of the outside air temperature in the past predetermined period (one week) and the predicted value of the outside air temperature on the current day, the control parameter table selection unit 20 selects either the control parameter table 10AS or 10BS, 10AW, Alternatively, either 10 BW is determined. In the present embodiment, the outside air temperature is used as the outside air information. Note that the outside air temperature on that day may be an actual measurement value.
The control parameter update unit 30 updates the value of the control parameter based on the control parameter table 10AS, 10AW, or 10BS, 10BW selected by the control parameter table selection unit 20.
The control unit 40 performs data management including input / output management such as processing and storage of various data acquired from the outside, such as the outside air temperature transmitted from the local control device 8 described later, and processing of various data transmitted to the outside. Various information processing such as processing and data flow control is executed. The control unit 40 is physically mainly composed of a central processing unit 41, a RAM 42 as a main storage device, a ROM 43, and the like. The central processing unit 41 is mainly composed of a CPU, and executes basic information processing such as data calculation and control. The constituent elements of the control unit 40 are communicatively connected to each other and exchange various information and data. Also, functional units that play a central role such as the control parameter table selection unit 20 and the control parameter update unit 30 appear in the control unit 40 by executing the control program.

The storage unit 45 is a hard disk (HDD), and stores a control parameter table 10, various data including past outside air temperature, various programs, and the like.
The communication unit 50 cooperates with the control unit 40 to realize various communication functions such as transmission / reception of information in the system and transmission / reception of data with the outside. For example, the predicted value of the outside air temperature on the day and the outside air discomfort index on the day are acquired from the weather information distribution source 5. Hereinafter, each part of the control parameter table 10, the control parameter table selection unit 20, and the control parameter update unit 30 which is a central part will be described.
(Configuration of each part of the remote management device)
(1-1) Control Parameter Table The control parameter table 10 is a table in which the outside air discomfort index is associated with the control parameters of the air conditioner 9a, and includes four control parameter tables 10AS, 10AW, 10BS, and 10BW. The control parameter tables 10AS and 10BS are for summer. The control parameter tables 10AW and 10BW are for winter. Tables 1 to 4 show examples of winter control parameter tables 10AW and 10BW and summer control parameter tables 10AS and 10BS, respectively. As a control parameter, the intermittent operation stop time ratio is adopted.

The intermittent operation is intended to save energy by intermittently operating and stopping the air conditioner 9a. The stop time ratio is the ratio of the time during which the heating operation or the cooling operation of the air conditioner 9a is stopped (the time in the thermo OFF state) to the total operation time of the air conditioner 9a. When the stop time ratio is 20%, for example, if the total operation time is 10 minutes, it means that the air conditioner 9a is operated with the thermo OFF for 2 minutes and the remaining 8 minutes are operated with the thermo ON. In the operation with the thermo OFF, the compressor is stopped and only blowing is performed. Hereinafter, for simplification of description, the stop time ratio of intermittent operation is simply expressed as a stop time ratio.
Here, an outside air discomfort index is adopted as outside air information. The outside air discomfort index is an index determined by the outside air temperature and humidity. FIG. 3 shows the relationship between the outdoor air discomfort index and the temperature of experience. It can be said that the outdoor air discomfort index 60 to 70 is the most comfortable environment. The discomfort increases as the discomfort index falls outside the range of 60 to 70, which is the most comfortable environment. The side where the outside air discomfort index is lower than 60 to 70 is the low temperature side, and the side where the outside air discomfort index is higher than 60 to 70 is the high temperature side.

Since both the heating operation mode and the cooling operation mode are the same in principle, in the following description, the heating operation mode, that is, the case where the winter control parameter tables 10AW and 10BW are applied will be described. Details of the cooling operation mode are omitted.
The control parameter tables 10AW and 10AS in Tables 1 and 3 are used in normal climatic conditions where climate change such as temperature is not severe. On the other hand, the control parameter tables 10BW and 10BS in Tables 2 and 4 have a climatic condition suddenly when, for example, the temperature has changed at an ordinary temperature, but the temperature has suddenly decreased one day. It is used when the discomfort level increases due to the change. In the case of such weather conditions, in order to improve the comfort level, the control parameter tables 10BS and 10BW are more effective than the control parameter tables 10AS and 10AW with respect to the value of the same control parameter (stop time ratio). A comfortable outdoor air discomfort index is associated. In other words, this means that the stop time ratio is associated with the same outside air discomfort index so that the stop time ratio is shortened and the air conditioning of the air conditioner 9a is strengthened.

(1-2) Control Parameter Table Selection Unit FIG. 2 is a diagram illustrating an example of the transition of the outside air temperature. FIG. 2 shows a case where the outside air temperature, which has been changing in the same degree for the past week or so, suddenly decreases. In the air conditioning control system 1, the control parameter table selection unit 20 first calculates the average value θpast of the outside air temperature for the past one week. The outside air temperature for the past one week is the outside air temperature in the building 9 acquired by the remote management device 7 via the local control device 8 and is stored in the storage unit 45. In addition, the control parameter table selection unit 20 acquires the predicted value θnow of the outside air temperature of the day from the weather information distribution source 5 via the communication unit 50 at a fixed time every day (6 am every morning). Then, the control parameter table selection unit 20 calculates a difference Δθ (= θnow−θpast) between the average value θpast of the outside air temperature for the past one week and the predicted value θnow of the outside air temperature on that day.

Next, the control parameter table selection unit 20 selects either the control parameter table 10AW or 10BW based on the relationship between Δθ calculated in this way and the predetermined threshold value θ0. Hereinafter, only the winter control parameter tables 10AW and 10BW will be described. Specifically, when the air conditioner 9a is operated in the heating operation mode, the control parameter table selection unit 20 determines that the following conditional expression 1 is obtained by Δθ calculated as described above and the predetermined threshold θ0. When it is satisfied, the control parameter table 10AW is selected.
Conditional expression 1: Δθ <θ0
On the other hand, when the conditional expression 1 is not satisfied, the control parameter table 10BW is selected.
In addition, in the case where the operation mode of the air conditioner 9a is the heating operation mode and in the case of the cooling operation mode, the magnitude symbols of the conditional expressions are reversed, but in principle, both are the same. The case of the heating operation mode is described. Note that the predetermined threshold value θ0 can be set by the user inputting, for example, 3 ° C., 5 ° C., 7 ° C. or the like.

(1-3) Control Parameter Update Unit The control parameter update unit 30 acquires the outdoor air discomfort index for the day from the weather information distribution source 5 via the communication unit 50. Next, the control parameter update unit 30 collates the control parameter table 10AW or 10BW selected by the control parameter table selection unit 20 with the acquired outside air discomfort index. Then, the corresponding stop time ratio is set as the stop time ratio (control parameter) of the day. Update of the value of the control parameter by the control parameter update unit 30 is executed once a day at 6 am every morning. For example, in the case of the control parameter table 10AW of Table 1, if the outside air discomfort index is 40, the stop time ratio is 10%.
(2) Local control device The local control device 8 receives the operation information of the air conditioner 9a generated by the remote management device 7 via the network 6, and is installed in the building 9 based on the operation information. The air conditioning of the air conditioner 9a is controlled. Further, the local control device 8 sends various information such as the set temperature of the air conditioner 9a installed in the building 9, the indoor temperature of the building 9, and the past outside air temperature to the remote management device 7 via the network. Send.

(3) Network In the air conditioning control system 1, the meteorological information distribution source 5, the remote management device 7, and the local control device 8 are communicatively connected via the Internet or the like. The local control device 8 and the building 9 are communicatively connected via a LAN (local area network).

Further, the control parameter table selection unit 20 calculates a difference Δθ (= θnow−θpast) between the predicted value of the outside air temperature on the current day acquired in step S1 and the average value θpast of the outside air temperature for the past one week. Then, it moves to step S3.
In step S3, the difference Δθ between the average value θpast of the outside air temperature in the past one week calculated in step S2 and the predicted value θnow of the outside air temperature on the current day satisfies the above-described conditional expression 1 in step S3.

In step S 21, the control parameter update unit 30 acquires the predicted value of the outdoor air discomfort index for the day from the weather information distribution source 5 via the communication unit 50. Then, the acquired outdoor air discomfort index is written in the RAM 42. Thereafter, the process proceeds to step S22.
In step S22, the control parameter update unit 30 reads the control parameter table 10AW or 10BW selected by the control parameter table selection unit 20 into the RAM 42 in the process of the control parameter table selection unit 20 in (1). Thereafter, the process proceeds to step S23.
In step S23, the control parameter update unit 30 initializes the counter Cnt with 1, and moves to step S24.
In step S24, the control parameter update unit 30 writes the information on the Cnt line of the control parameter table 10AW or 10BW read into the RAM 42 in step S22 into the RAM 42. Thereafter, the process proceeds to step S25.

In step S25, the control parameter update unit 30 determines whether or not the predicted value θnow of the outdoor air discomfort index for the day satisfies the condition representing the range of the outdoor air discomfort index in the first column of the Cnt row of the control parameter table 10AW or 10BW. Determine. The predicted value θnow of the outdoor air discomfort index on that day is obtained by the control parameter update unit 30 in step S21 and written in the RAM 42. The Cnt line of the control parameter table 10AW or 10BW is the one written by the control parameter update unit 30 in the RAM 42 in step S24. If the condition is satisfied as a result of the determination, the process moves to step S26. If the condition is not satisfied as a result of the determination, the process moves to step S27.
In step S26, the control parameter update unit 30 writes the information (control parameter, that is, the stop time ratio) in the second column of the Cnt row of the control parameter table 10AW or 10BW written in the RAM 42 in step S24 to the new control. Set as a parameter value. Thereafter, the process proceeds to an end process of step S28.

In step S27, the value of the counter Cnt is incremented by 1. Thereafter, the process proceeds to step S24.
In step S28, a control parameter update end process is executed, and the process of the control parameter update unit 30 ends.
[Characteristics of air conditioning control system]

The control parameter table 10AW is used in normal climatic conditions where climate change such as outside air temperature is not severe. On the other hand, the control parameter table 10BW is used, for example, when the outside air temperature, which has been changing as normal, drops rapidly. In the winter season, when the outside air temperature changes abruptly, even if the outside air temperature is the same, there may be a difference in the cold feel. In the air conditioning control system 1, assuming such a case, the control parameter table 10BW is compared with the control parameter table 10AW in order to improve the comfort level even if the objective outside air discomfort index is the same. A more comfortable index is associated with the same control parameter (stop time ratio) value. In other words, this means that the stop time ratio is associated with the same outside air discomfort index so that the stop time ratio is shortened and the air conditioning of the air conditioner 9a is further strengthened. For this reason, even when the outside air temperature, which has been in a normal state in winter, suddenly decreases, an improvement in comfort can be expected by air-conditioning control that takes into consideration the temperature of sensation.

(2)
In the air conditioning control system 1, the average value θpast of the outside air temperature in the past predetermined period (one week) is calculated, and the difference from the outside air temperature θnow of the day is calculated. For this reason, the past fine fluctuations in the outside air temperature are absorbed, and the tendency of a large change in the outside air temperature is reflected in the air conditioning, so that the comfort level can be further improved.
(3)
In the air conditioning control system 1, the control parameter value of the air conditioner 9a is updated based on the control parameter table 10AW or 10BW selected by the control parameter table selection unit 20 and the outdoor air discomfort index on that day. Since the outside air discomfort index is calculated based on the outside air temperature, humidity, and the like, it can be considered that it constantly fluctuates even during the day. On the other hand, the outdoor air discomfort index on that day is a predicted value acquired from the weather information distribution source 5. Due to recent developments in weather forecasting technology, the accuracy of predicted temperature values has been dramatically improved, and reliability has been improved. For this reason, there is a possibility that air-conditioning control can be executed without being affected by minute fluctuations in the outdoor air discomfort index during the day, and an improvement in comfort and an energy saving effect can be expected.
[Modification of First Embodiment]
Although the first embodiment of the present invention has been described above, the present invention is not limited to the first embodiment, and various modifications can be made without departing from the scope of the invention.

(Modification A)
The air-conditioning control system 1 according to the first embodiment has two control parameter tables 10AW and 10BW as the control parameter table 10 only for the winter season, and the control parameter table selection unit 20 selects one of them. I chose. However, the number of control parameter tables 10 is not limited to two. For example, the control parameter table 10 includes three control parameter tables 10 and the control parameter table selection unit 20 selects one control parameter table 10 from the three control parameter tables 10. Good. Modification A of the first embodiment includes three summer control parameter tables 10AAS, 10ABS, 10ACS, and winter control parameter tables 10AAW, 10ABW, 10ACW in which an outdoor air discomfort index is associated with one type of control parameter. For example, it can be applied to the following cases.

A slightly warm day in midwinter may feel warmer than a warmer day in early winter. When it feels warm in terms of experience, it is conceivable that heating can be slightly reduced to improve the energy saving effect. In the air conditioning control system 1 according to the modified example A of the first embodiment, on the day of a normal temperature, the normal control parameter table 10AA. The control parameter table 10AB in which the discomfort index and the control parameter are associated with each other. When the user feels somewhat warm, the outside air is uncomfortable so that air conditioning is performed weakly (that is, power consumption is suppressed). By selecting the control parameter table 10AC in which the index and the control parameter are associated with each other, an energy saving effect can be expected in addition to an improvement in the comfort level.
[Components of Modification A]
Here, the components of Modification A will be described. Only the remote management device 7 of Modification A will be described. The weather information distribution source 5, the network 6, the local control device 8, and the building 9 are exactly the same as in the first embodiment. Details of the description overlapping with the first embodiment are also omitted.

(Overall configuration of remote management device)
The remote management device 7 of Modification A includes a control parameter table 10, a control parameter table selection unit 20, a control parameter update unit 30, a control unit 40, a storage unit 45, and a communication unit 50.
(Configuration of each part of the remote management device)
Hereinafter, each part of the control parameter table 10, the control parameter table selection unit 20, and the control parameter update unit 30, which is a central part in Modification A, will be described.
(A-1) Control parameter table 10
The modified example A includes three summer control parameter tables 10AAS, 10ABS, 10ACS, and three winter control parameter tables 10AAW, 10ABW, 10ACW in which the outdoor air discomfort index is associated with one type of control parameter. Yes. These control parameter tables 10AAS, 10ABS, 10ACS, 10AAW, 10ABW, 10ACW are stored in the storage unit 45. Hereinafter, only the control parameter tables 10AAW, 10ABW, 10ACW for the case where the air conditioner is operated in the heating operation mode, that is, the winter season will be described.

(A-2) Control Parameter Table Selection Unit The control parameter table selection unit 20 controls the control parameter based on the difference between the average value of the outside air temperature in the past predetermined period (the past one week) and the predicted value of the outside air temperature on that day. One of the tables 10AAW, 10ABW, or 10ACW is selected. Note that the outside air temperature on that day may be an actual measurement value.
The control parameter table selection unit 20 calculates the average value θ1past of the outside air temperature for the past one week via the local control device 8 and the communication unit 50. The outside air temperature for the past one week is the outside air temperature in the building 9 acquired by the remote management device 7 via the local control device 8 and is stored in the storage unit 45. In addition, the control parameter table selection unit 20 acquires the predicted value θ1now of the outside air temperature of the day from the weather information distribution source 5 through the communication unit 50 at 6:00 every morning. Then, a difference Δθ1 (= θ1past−θ1now) between the average value θ1past of the outside air temperature in the past one week and the predicted value θ1now of the outside air temperature on the day is calculated. Next, the control parameter table selection unit 20 compares Δθ1 calculated in this way with two predetermined threshold values θ11 and θ12. Based on the result of the comparison, one of the control parameter tables 10AAW, 10ABW, or 10ACW is selected. Hereinafter, this will be described. Tables 5 to 7 show examples of winter control parameter tables 10AAW, 10ABW, and 10ACW, respectively.

The control parameter table 10AAW is used in a normal climate. The control parameter table 10ABW is used, for example, when the outside air temperature, which has been changing as normal in winter, suddenly drops from around the day (when the degree of discomfort is high). Conversely, the control parameter table 10ACW is also used in the winter when the outside air temperature rises from around the day (when the degree of discomfort is low in terms of experience).
In the case where the operation mode of the air conditioner 9a is the heating operation mode and the case of the cooling operation mode, for example, the size symbols of the selected conditional expressions are reversed. The case of the operation mode will be described. When the air conditioner 9a is operating in the heating operation mode, the control parameter table selection unit 20 compares Δθ1 calculated as described above with two predetermined threshold values θ11 and θ12. As a result of the comparison, if the following conditional expression 2 is satisfied, the control parameter table 10AAW is selected. The predetermined two threshold values θ11 and θ12 can be input and set by the user.

Conditional expression 2: θ11 <Δθ1 <θ12
When the following conditional expression 3 is satisfied, the control parameter table ABW is selected.
Conditional expression 3: Δθ1 ≧ θ12
In cases other than the above, the control parameter table ACW is selected.
(A-3) Control Parameter Update Unit The control parameter update unit 30 updates the value of the control parameter based on the control parameter table 10AAW, ABW, or ACW selected by the control parameter table selection unit 20.
Since the control unit 40, the storage unit 45, and the communication unit 50 are the same as those in the first embodiment, description thereof is omitted here.
[Operation of Modification A]
Here, the operation of Modification A will be described. Since the operation of the control parameter update unit 30 is the same as that in the first embodiment, description thereof is omitted here, and only the control parameter table selection unit 20 is described.

(A-1) Process Flow in Control Parameter Table Selection Unit Here, the process flow in the control parameter table selection unit 20 will be described using a flowchart. FIG. 6 is a flowchart showing the flow of processing in the control parameter table selection unit 20 of Modification A.
In step S 31, the control parameter table selection unit 20 acquires the predicted value θ 1 now of the outdoor temperature of the day from the weather information distribution source 5 via the communication unit 50 and writes it in the RAM 42. Thereafter, the process proceeds to step S32. In Modification A, the acquisition of the predicted value θ1now is set to be executed every morning at 6:00.
In step S32, the control parameter table selection unit 20 calculates an average value θ1past of the outside air temperature for the past one week via the local control device 8 and the communication unit 50. Further, the control parameter table selection unit 20 calculates a difference Δ1θ (= θ1past−θ1now) between the average value θ1past of the outside air temperature in the past one week and the predicted value θ1now of the outside air temperature of the day acquired in step S1. Then, it moves to step S33.

In step S33, the control parameter table selection unit 20 determines whether or not the difference Δθ1 between the average value θ1past of the outside air temperature in the past week and the predicted value θ1now of the outside air temperature on the day satisfies the following conditional expression 2. The average value θ1past of the outside air temperature for the past one week is calculated by the control parameter table selection unit 20 in step S32. Here, θ11 and θ12 are predetermined threshold values.
Conditional expression 2: θ11 <Δθ1 <θ12
If conditional expression 2 is satisfied, the process moves to step S34, and if not, the process moves to step S35.
In step S34, the control parameter table selection unit 20 selects the control parameter table 10AAW and writes it to the RAM 42. Thereafter, the process proceeds to step S38.

In step S35, whether or not the difference Δθ1 between the average value θ1past of the outside temperature for the past one week calculated in step S32 and the predicted value θ1now of the outside temperature on that day satisfies the conditional expression 3 in step S35. Determine if.
Conditional expression 3: Δθ1 ≧ θ12
If conditional expression 3 is satisfied, the process moves to step S36, and if not, the process moves to step S37.
In step S 36, the control parameter table selection unit 20 selects the control parameter table 10 ABW and writes it in the RAM 42. Thereafter, the process proceeds to step S38.
In step S37, the control parameter table selection unit 20 selects the control parameter table 10ACW and writes it in the RAM. Thereafter, the process proceeds to step S38.

In step S38, an end process for determining the control parameter table is performed.
[Features of Modification A]
For example, in the winter season, when the air conditioner 9a is operated in the heating operation mode and the outside air temperature rapidly decreases, the control parameter table selection unit 20 selects the control parameter table 10ABW. In this control parameter table 10ABW, the outdoor air discomfort index and the control parameters are associated with each other so that air conditioning is executed more strongly than in the control parameter table 10AAW. On the other hand, for example, when a relatively warm day continues in the coldest time of midwinter, the control parameter table selection unit 20 selects the control parameter table 10ACW. In this control parameter table 10ACW, the outdoor air discomfort index and the control parameter are associated with each other so that the air conditioning is performed weaker (that is, the power consumption is suppressed) as compared with the control parameter table 10AAW. For this reason, in addition to the improvement in comfort, an energy saving effect can be expected.

(Modification B)
In the air conditioning control system 1 according to the first embodiment, the control parameter table 10 has one type of control parameter for the air conditioner 9a. However, the control parameter table 10 may have a plurality of control parameters for the air conditioner 9a.
Here, the case where the operation mode of the air conditioner 9a is the heating operation mode will be described. The same applies in principle when the operation mode of the air conditioner 9a is the cooling operation mode, and the control direction is simply reversed. For this reason, the description in the case where the operation mode of the air conditioner 9a is the cooling operation mode is omitted here.
In the modified example B, the capacity limiting rate is adopted as the second control parameter. The capacity restriction is intended to save energy by restricting the capacity of the air conditioner 9a. The capacity limit rate is a ratio of the capacity limit. For example, assuming that the normal capacity of the air conditioner 9a is 100 at the maximum, the capacity in this state is 80 at the maximum if the capacity limit rate is 80%.

In general, the method of performing air conditioning control by stopping the heating operation or cooling operation of the air conditioner 9a (referred to as a control method based on the stop time ratio) is more comfortable than the method of controlling the air conditioner 9a at the capacity limit rate. The power consumption is reduced as a result although the degree is somewhat low. For this reason, when the air conditioner 9a is operated in the heating operation mode in winter, for example, if a method as described below is adopted, a further energy saving effect can be expected.
In early winter, December, the outside air temperature generally tends to be somewhat higher than in January or February. For this reason, the air conditioning control is executed only by controlling the stop time ratio. By adopting such a method, the comfort level is slightly low, but the power consumption can be suppressed. In January, when cold weather becomes increasingly severe, the air conditioning control is executed with both the stop time ratio and the capacity limit ratio enabled. Then, in February, which is generally the coldest in winter, air conditioning control is executed only by controlling the capacity limit rate.

However, such a tendency of cold is only a guideline, and other more precise methods, for example, a method that takes into account not only the season but also the outside air temperature etc. can be adopted, and it is desirable. . However, here, in order to simplify the description, the control by the above-described method will be described. Hereinafter, Modification B will be described.
In the modified example B, there are four control parameter tables 10A1S, 10A2S, 10A1W, and 10A2W in total, two for summer and two for winter, in which the outdoor air discomfort index is associated with the stop time ratio. In addition, there are two control parameter tables 10B1S, 10B2S, 10B1W, and 10B2W in total, two for summer and two for winter, each of which is associated with an outside air discomfort index and a capacity restriction rate. The control parameter tables 10A1S, 10A2S, 10B1S, and 10B2S are for summer. The control parameter tables 10A1W, 10A2W, 10B1W, and 10B2W are for winter.

The modification B further includes a control parameter table valid / invalid switching unit 25 that validates or invalidates some or all of the plurality of control parameter tables 10 selected by the control parameter table selection unit 20. In the modification B, for example, both the two control parameter tables 10A1W or 10A2W and 10B1W or 10B2W may be valid, but conversely, both may be invalid. .
Hereinafter, each component of the modified example B will be described. Here, only the remote management device 7 will be described, and the weather information distribution source 5, the network 6, and the local control device 8 are exactly the same as those in the first embodiment, and thus description thereof is omitted. Further, the functions of the control parameter table selection unit 20 and the control parameter update unit 30 are the same as those in the first embodiment.

(B-1) Control Parameter Table Selection Unit The control parameter table selection unit 20 calculates the average value θ2past of the outside air temperature for the past one week via the local control device 8 and the communication unit 50. In addition, the predicted value θ2now of the outside air temperature of the day is acquired from the weather information distribution source 5 through the communication unit 50 at a fixed time every day (6 am every morning). Then, the difference Δθ2 (= θ2past−θ2now) between the average value θ2past of the outside air temperature in the past one week and the predicted value θ2now of the outside air temperature on the day is calculated. Next, the control parameter table selection unit 20 selects either the control parameter table 10A1W or 10A2W based on the relationship between Δθ2 calculated in this way and the predetermined threshold value θ2. Similarly, one of the control parameter tables 10B1W or 10B2W is selected. Tables 11 to 14 show examples of winter control parameter tables 10A1W, 10A2W, 10B1W, and 10B2W, respectively. Hereinafter, the case for the winter season, that is, the heating operation mode will be described, and the description for the summer season, that is, the cooling operation mode will be omitted.

When the air conditioner 9a is operated in the heating operation mode, the control parameter table selection unit 20 compares Δθ2 calculated as described above with a predetermined threshold value θ2. As a result of the comparison, when the following conditional expression 4 is satisfied, the control parameter tables 10A1W and 10B1W are selected.
Conditional expression 4: Δθ2 <θ2
On the other hand, when the conditional expression 4 is not satisfied, the control parameter tables 10A2W and 10B2W are selected.
In addition, the case where the operation mode of the air conditioner 9a is the heating operation mode and the case of the cooling operation mode, the magnitude symbols of the selected conditional expressions are reversed, but both are the same, and the processing in one operation mode is the same. From this flow, it is easy to derive the procedure of the processing flow in the other operation mode. For this reason, here, the case of the heating operation mode will be described, and the description of the case of the cooling operation mode will be omitted.

(B-2) Control Parameter Table Valid / Invalid Switching Unit The control parameter table valid / invalid switching unit 25 validates or invalidates part or all of the control parameter table 10A1W selected by the control parameter table selection unit 20 based on the season. To. When the air conditioner 9a is in the cooling operation mode, two control parameter tables 10A1W or 10A2W in which the outdoor air discomfort index and the stop time ratio are associated with each other are effective in the early winter, and the external air discomfort index and the capacity restriction rate are associated with each other. The two control parameter tables 10B1W or 10B2W are invalid. On the other hand, in mid-winter, the two control parameter tables 10B1W or 10B2W in which the outdoor air discomfort index and the capacity restriction rate are associated are valid, and the two control parameter tables 10A1W in which the outdoor air discomfort index and the stop time ratio are associated with each other. Or 10A2W becomes invalid.

In the modified example B, the control parameter table valid / invalid switching unit 25 determines whether the control parameter table is valid or invalid based on the season. However, the control parameter table valid / invalid switching unit 25 determines the control parameter based on other conditions such as the outside air temperature. The validity or invalidity of the table 10 may be determined.
(B-3) Control Parameter Update Unit Since the control parameter update unit 30 is exactly the same as that in the first embodiment, description thereof is omitted here.
[Operation of Modification B]
Here, the operation of Modification B will be described with reference to a flowchart. FIG. 7 is a flowchart showing the flow of processing in the control parameter table selection unit 20 in Modification B. The processing of this part is almost the same as in the first embodiment. In FIG. 7, the part of “10” is omitted in the reference numerals of the control parameter table 10A1W and the like for the sake of space.

(B-1) Control parameter table selection unit 20
In step S 41, the control parameter table selection unit 20 acquires a predicted value of the outside air temperature of the day from the weather information distribution source 5 via the communication unit 50 and writes it in the RAM 42. Thereafter, the process proceeds to step S42. The acquisition of the predicted value is set to be executed every morning at 6:00.
In step S42, the control parameter table selection unit 20 calculates the average value θ2past of the outside air temperature for the past one week via the local control device 8 and the communication unit 50. The outside air temperature for the past one week is the outside air temperature in the building 9 acquired by the remote management device 7 via the local control device 8 and is stored in the storage unit 45. Further, the control parameter table selection unit 20 calculates a difference Δθ2 (= θ2past−θ2now) between the average value θ2past of the outside air temperature in the past one week and the predicted value θ2now of the outside air temperature on the day acquired in step S41. Thereafter, the process proceeds to step S43.

In step S43, whether or not the difference Δθ2 between the average value θ2past of the outside temperature for the past one week calculated in step S42 and the predicted value θ2now of the outside temperature of the day satisfies the conditional expression 4 in step S43. Determine if. Here, θ2 is a predetermined threshold value.
Conditional expression 4: Δθ2 <θ2
If the conditional expression 4 is satisfied, the process moves to step S44, and if not, the process moves to step S45.
In step S44, the control parameter table selection unit 20 selects the control parameter tables 10A1W and 10B1W and writes them in the RAM. Thereafter, the process proceeds to an end process of step S46.
In step S45, the control parameter table selection unit 20 selects the control parameter tables 10A2W and 10B2W and writes them in the RAM. Thereafter, the process proceeds to an end process of step S46.

In step S46, control parameter table determination end processing is performed.
(B-2) Control Parameter Table Valid / Invalid Switching Unit Next, the operation of the control parameter table valid / invalid switching unit 25 in Modification 2 will be described with reference to a flowchart. FIG. 8 is a flowchart showing the flow of processing in the control parameter table valid / invalid switching unit 25. In FIG. 8, the part of “10” is omitted in the reference numerals of the control parameter table 10A1W and the like for the sake of space.
In step S51, the control parameter table valid / invalid switching unit 25 writes the date of the day in the RAM.
In step S52, the control parameter table valid / invalid switching unit 25 determines whether the date of the current day written in the RAM 42 in step S51 is December. If it is December, the process proceeds to step S54. If it is not December, the process proceeds to step S53.

In step S53, the control parameter table valid / invalid switching unit 25 determines whether the current date written in the RAM 42 in step S51 is January. If it is January, the process proceeds to step S55. If it is not January, the process proceeds to step S56.
In step S54, the control parameter table valid / invalid switching unit 25 validates the control parameter table 10A1W or 10A2W and invalidates the control parameter table 10B1W or 10B2W.
In step S55, the control parameter table valid / invalid switching unit 25 validates both the control parameter table 10A1W or 10A2W and the control parameter table 10B1W or 10B2W.
In step S56, the control parameter table valid / invalid switching unit 25 invalidates the control parameter table 10A1W or 10A2W and validates the control parameter table 10B1W or 10B2W.

In step S57, the process of the control parameter table valid / invalid switching unit 25 ends.
(B-3) Control Parameter Update Unit The control parameter update unit 30 executes control parameter update based on the control parameter table 10A1W and the like switched by the control parameter table valid / invalid switching unit 25. Since the operation is exactly the same as in the first embodiment, description thereof is omitted.
[Features of Modification B]
In general, the method of controlling the air conditioning by stopping the heating operation or the cooling operation of the air conditioner 9a is slightly less comfortable than the method of controlling the air conditioner 9a with the capacity restriction rate, but it consumes as a result. Power can be reduced.
In the modified example B, air conditioning control is executed only in the control of the stop time ratio in December in the early winter. In January, when cold weather becomes increasingly severe, the air conditioning control is executed with both the stop time ratio and the capacity limit ratio enabled. Then, in February, which is generally the coldest in winter, air conditioning control is executed only by controlling the capacity limit rate. For this reason, further energy saving effect can be expected.

(Modification C)
In the air-conditioning control system according to the first embodiment, the intermittent operation stop time ratio is adopted as the control parameter, but a capacity restriction rate may be adopted instead. Also in this case, an improvement in comfort and an energy saving effect can be expected.
(Modification D)
In the modified example B, the control parameter table selection unit 20 selects one of the control parameter tables 10A1W and 10A2W having the same control parameter, and the control parameter tables 10B1W and 10B2W having the same control parameter. Either one was selected. However, for example, the control parameter table selection unit 20 may select one control parameter table 10C1 or the like from three or more control parameter tables 10C1 or the like having the same control parameter. In addition, the control parameter table selection unit 20 includes a plurality of control parameter tables 10C1, 10D1, 10E1, and the like that associate each control parameter with an outdoor air discomfort index for three or more types of control parameters. One control parameter table 10C1, 10D1, 10E1, etc. may be selected from a plurality of control parameter tables 10C1, 10D1, 10E1, etc. having control parameters.

(Modification E)
In the air-conditioning control system 1 according to the first embodiment, the time for changing the control parameter is 6 o'clock in the early morning, but it is not necessary to be limited to this time, and may be changed a plurality of times a day. For example, the control parameter table may be reread based on the difference between the actual measured value of the outside air temperature at every hour and the average value of the outside air temperature at the same time in the past predetermined period. It should be noted that the time at which the actual measured value of the outside air temperature on the day is acquired and the time to be measured in order to calculate the average value of the outside air temperature in the past predetermined period must be the same time. This is because, for example, in the early morning and noon, the outside air temperature is completely different, so that a correct comparison cannot be made.
(Modification F)
In the air-conditioning control system 1 according to the first embodiment, the outside air temperature of the day uses the predicted value acquired from the weather information distribution source 5 via the network 6, but actually measured the outside air temperature of the day. It may be a value. Even in this case, a sudden change in the outside air temperature can be captured and used for selection of the control parameter table 10. However, the measurement time of the daily outside air temperature is set to a fixed time. In the same day, for example, measured values in the early morning, when the lowest temperature is measured, and measured values in the time zone, where the highest temperature is measured, are handled in the same way. This is because there is no meaning.

(Modification G)
In the air conditioning control system 1 according to the first embodiment, the remote management device 7 includes the control unit 40 that processes the weather information acquired from the weather information distribution source 5 and generates the operation information of the air conditioner 9a. . The local control device 8 receives the operation information of the air conditioner 9a transmitted from the control unit 40 provided in the remote management device 7. And the local control apparatus 8 controlled the air conditioner 9a installed in the building 9 based on the operation information of this air conditioner 9a. However, the control unit 40 and the storage unit 45 may be provided in the local control device 8. Even in such a configuration, using the actual measurement value installed in the same place as the building 9 as the outside air temperature on the day, the degree of comfort is achieved by fine air conditioning control that reflects changes in the outside air temperature and outside air information. Improvement can be expected.
(Modification H)
In the air conditioning control system 1 according to the first embodiment, the control parameter table selection unit 20 controls the cooling (summer) control parameter tables 10AS and 10BS based on the operation mode of the air conditioner 9a, or the heating (winter) control. The parameter table 10AW or 10BW was selected, but it was selected based on the date of the day (for example, for cooling from May to September and for heating from October to April), outside temperature, etc. May be.
[Second Embodiment]
In the air conditioning control system 1 according to the first embodiment of the present invention, the control parameter table 10 is preset in the system. However, the control parameter table 10 may be automatically generated.

The air conditioning control system 2 according to the second embodiment of the present invention includes a control parameter table generation unit 120 that automatically generates a timed control parameter table 115 based on the control parameter table 110.
Here, the air conditioning control system 2 according to the second embodiment will be described with reference to the drawings. A description will be given assuming that the air conditioner 9a is performing a heating operation in winter. The same is true in principle when the cooling operation is performed in summer. Therefore, a detailed description of the cooling operation is omitted.
As in the case of the air conditioning control system 1 according to the first embodiment, the air conditioning control system 2 according to the second embodiment selects an appropriate control parameter table from a plurality of control parameter tables 10 included in the system in advance. The control parameter table selection unit 20 is not provided. Instead, it is characterized by including a control parameter table generation unit 120 that generates a new timed control parameter table 115 from a control parameter table 110 included in the system in advance. The control parameter table generation unit 120 generates a timed control parameter table 115 every day at a predetermined time (6 o'clock in the morning), and the previously generated timed control parameter table 115 disappears at this timing and is newly generated. The timed control parameter table 115 is replaced. Then, the control parameter update unit 130 updates the value of the control parameter based on the timed control parameter table 115 and the outside air discomfort index.
[Components of the air conditioning control system according to the second embodiment]
(Overall configuration)
As shown in FIG. 11, the air conditioning control system 2 according to the second embodiment collects weather information from the weather information distribution source 5 and the weather information distribution source 5 via the network 6, and the air conditioner 9 a Based on the operation information of the remote management device 7 for generating the operation information, the building 9 in which the air conditioner 9a is installed, and the air conditioner 9a supplied from the remote management device 7 via the network 6, the network 6 is used. And a local control device 8 for controlling the air conditioner 9a of the building 9.

Hereinafter, only the remote management device 7 will be described.
(1-1) Remote Management Device The remote management device 7 includes a control parameter table 110, a timed control parameter table 115, a control parameter table generation unit 120, a control parameter update unit 130, a control unit 40, a storage unit 45, and a communication unit. 50. The control parameter table 110 is a table in which the outside air discomfort index is associated with the control parameters of the air conditioner 9a. Since the control parameter table 110 is the same as the control parameter table 10 in the second embodiment, a detailed description thereof is omitted here. The control parameter table 110 is stored in the storage unit 45.
Based on the difference between the average value of the outside air temperature in the past predetermined period (one week) and the predicted value of the outside air temperature on the current day, the control parameter table generating unit 120 performs the control parameter table at a predetermined time (6 am every morning). From 110, a timed control parameter table 115 is generated. This time-limited control parameter 115 has a limited expiration date in which it functions effectively. The generated timed control parameter table 115 is valid until the control parameter table generating unit 120 generates a new timed control parameter table 115 at the next timing. The old timed control parameter table 115 disappears when the new timed control parameter table 115 is generated at the next timing, and is replaced with the newly generated timed control parameter table 115.

The control parameter update unit 130 updates the value of the currently used control parameter based on the timed control parameter table 115 generated by the control parameter table generation unit 120.
In the air conditioning control system 2 according to the second embodiment, the control parameter table 110, the control parameter update unit 120, the storage unit 45, the communication unit 50, and the control unit 40 are the same as those in the air conditioning control system 1 according to the first embodiment. Since it is the same as a corresponding component, description is abbreviate | omitted here.
Hereinafter, the control parameter table generation unit 120, which is a central part, will be mainly described.
(1-1) Control Parameter Table Generation Unit The control parameter table generation unit 120 determines the difference Δθ3 (= θ3past−) between the average value θ3past of the outside air temperature in the past predetermined period (one week) and the predicted value θ3now of the outside air temperature of the day. Based on θ3now), a timed control parameter table 115 is generated from the control parameter table 110 at a predetermined time (6 o'clock every morning). The time-limited control parameter table 115 has a limited expiration date in which it functions effectively.

The new timed control parameter table 115 is generated by correcting the value of the outside air discomfort index in the control parameter table 110 by a value obtained by multiplying the value of Δθ3 by the correction coefficient α. FIG. 10 is a graph showing the relationship between the outside air temperature and the outside air discomfort index. As shown in this graph, when the outside air temperature changes by 5 ° C., the outside air discomfort index changes by about 4. Therefore, for example, 4/5 = 0.8 is used as α. This will be described with an example. The control parameter table 110 and the time-limited control parameter table 115 newly generated based on the control parameter table 110 are for winter and summer, that is, for heating operation mode and cooling operation mode. However, only winter use will be described here. Tables 15 and 16 show examples of the control parameter table 110 and the timed control parameter table 115 applied in winter, that is, in the heating operation mode, respectively.

A method for generating the timed control parameter table 115 will be described with reference to these tables.
In the winter season, it is assumed that Δθ3 is + 3.75 ° C., that is, the outside air temperature θ3now on the current day is 3.75 ° C. lower than the average value of the outside air temperature θ3past in the past predetermined period (one week). At this time, the value of the outdoor air discomfort index in the first column of each row of the control parameter table 110 is corrected by adding + 3.75 ° C. × α (0.8). On the other hand, it is assumed that Δθ3 is −3.75 ° C., that is, the outside air temperature θ3now of the day has increased by 3.75 ° C. compared with the average value θ3past of the outside air temperature in the past predetermined period (one week). At this time, the value of the outdoor air discomfort index in the first column of each row of the control parameter table 110 is added by −3.75 ° C. × α (0.8), that is, 3.75 ° C. × α (0.8) is subtracted. To correct it.

In the summer season, it is assumed that Δθ3 is −3.75 ° C., that is, the outside air temperature of the day has increased by 3.75 ° C. compared to the average value of the outside air temperature in the past predetermined period. At this time, the value of the outdoor air discomfort index in the first column of each row of the control parameter table 110 is corrected by adding −3.75 ° C. × α (0.8). On the other hand, it is assumed that Δθ3 is + 3.75 ° C., that is, the outside air temperature on the current day is 3.75 ° C. lower than the average value of the outside air temperature in the past predetermined period. At this time, the value of the outdoor air discomfort index in the first column of each row of the control parameter table 110 is corrected by adding + 3.75 ° C. × α (0.8).
The timed control parameter table 115 in Table 16 and Table 18 shows the case where Δθ3 is + 3.75 ° C. in winter and the case where Δθ3 is −3.75 ° C. in summer. Compared to the average value of the outdoor temperature in the past predetermined period in the winter, the outdoor temperature of the day falls by 3.75 ° C. In comparison with the average value of the outdoor temperature in the past predetermined period in the summer, This is a case where the outside air temperature on that day has increased by 3.75 ° C. In this case, in winter, “˜39” on the first line of the item of the outdoor air discomfort index in the control parameter table is corrected to “˜42”. On the other hand, in the summer, “80-” in the first row is corrected to “77-”. That is, correction is performed so that a more comfortable index is associated with the value of the same control parameter (stop time ratio). In other words, this means that the stop time ratio is associated with the same outside air discomfort index so that the stop time ratio is shortened and the air conditioning of the air conditioner 9a is further strengthened. This means that in the air conditioning control system 1 of the first embodiment, the timed control parameter table 115 corresponding to the control parameter table B, which is selected when it is uncomfortable, is generated.
[Operation of Second Embodiment]
Since the configuration of the control parameter table 110 and the operation of the control parameter update unit 130 are the same as those in the first embodiment, detailed description thereof is omitted, and here, the operation of the control parameter table generation unit 120 will be mainly described. To do.

(1) Operation of Control Parameter Table Generation Unit FIG. 9 is a flowchart showing the flow of processing in the control parameter table generation unit 120.
In step S 61, the control parameter table generation unit 120 acquires the operation mode of the air conditioner 9 a via the local control device 8 and the communication unit 50 and writes it in the RAM 42. Thereafter, the process proceeds to step S62.
In step S 62, the control parameter table generating unit 120 acquires the predicted value θ 3 now of the outside air temperature of the day from the weather information distribution source 5 via the communication unit 50 and writes it in the RAM 42. Thereafter, the process proceeds to step S63. The acquisition of the predicted value is set to be executed every morning at 6:00.

In step S63, the control parameter table generation unit 120 calculates the average value θ3past of the outside air temperature for the past one week via the local control device 8 and the communication unit 50. Furthermore, the predicted value θ3now of the outside air temperature of the day acquired in step S61 is subtracted from the average value θ3past of the outside air temperature for the past one week, and a difference Δθ3 (= θ3past−θ3now) is calculated. Thereafter, the process proceeds to step S64.
In step S64, the difference Δθ3 (= θ3past−θ3now) between the average value θ3past of the outside air temperature in the past one week calculated in step S63 and the predicted value θ3now of the outside air temperature on the day is substituted into the following conditional expression 5: The correction value C is calculated and the result is written in the RAM 42.
Conditional expression 5: C = Δθ3 × 0.8
Thereafter, the process proceeds to step S65.

In step S65, it is determined whether the operation mode of the air conditioner 9a written in the RAM 42 in step S61 is the heating operation mode. If it is in the heating operation mode, the process moves to step S66. If it is not in the heating operation mode, the process moves to step S67.
In step S66, the numerical range of the first column of each row of the control parameter table 110 is corrected by adding the value of the correction value C calculated in step S64. After the correction is completed for all the rows of the control parameter table 110, the process proceeds to step S69.
In step 67, it is determined whether the operation mode of the air conditioner 9a written in the RAM 42 in step S61 is the cooling operation mode. If it is in the cooling operation mode, the process moves to step S68, and if not, the process moves to step S69.
In step S68, the numerical value range in the first column of each row of the control parameter table 110 is added with a value obtained by multiplying the value of the correction value C calculated in step S64 by -1 (a value obtained by reversing the sign). to correct. After the correction is completed for all the rows of the control parameter table 110, the process proceeds to step S69.

In step S69, a timed control parameter table generation end process is executed.
