On the other hand, in recent years, energy saving is also required for air conditioning systems. In this case, it is necessary to predict what kind of energy-saving control should be executed to change the room temperature so that comfort can be maintained even when the air conditioner is operated in the energy-saving control mode. However, when the room temperature is estimated by setting parameters from the past operation results as in the prior art described in Patent Document 1, it is possible to predict the room temperature when energy saving control having no past operation results is executed. Can not. For this reason, sufficient energy saving control cannot be performed, and the target power consumption may not be reached.

Therefore, an object of the present invention is to estimate the room temperature when the energy saving control is executed even when the energy saving control having no operation record is executed.

The air conditioning system of the present invention is an air conditioning system including an air conditioner and a room temperature estimation device that estimates the room temperature with respect to the outside temperature when the air conditioner is operated with a predetermined set temperature and a predetermined energy saving control pattern. The room temperature estimation device is a room temperature estimation model that calculates an estimated room temperature for the outside temperature when the air conditioner is operated according to the corresponding set temperature and the corresponding energy saving control pattern in each cell of the matrix of the set temperature and the energy saving control pattern. A room temperature estimation model database storing the above and an estimated room temperature calculation unit that calculates the estimated room temperature based on the room temperature estimation model database, and the estimated room temperature calculation unit has a predetermined set temperature in the room temperature estimation model database. When a room temperature estimation model corresponding to a predetermined energy saving control pattern is stored, the estimated room temperature with respect to the outside temperature is calculated using the room temperature estimation model stored in the room temperature estimation model database, and the room temperature estimation model database is used. If a room temperature estimation model corresponding to a predetermined set temperature and a predetermined energy-saving control pattern is not stored in, the estimated room temperature with respect to the outside temperature is calculated using the room temperature estimation model in a plurality of cells in which the room temperature estimation model is stored. The feature is that each is calculated and the estimated room temperature of each of the calculated plurality of cells is interpolated to calculate the estimated room temperature with respect to the outside temperature when the air conditioner is operated with a predetermined set temperature and a predetermined energy saving control pattern. do.

As a result, when there is no operation record of the air conditioner with the predetermined set temperature and the predetermined energy saving control pattern, and the room temperature estimation model corresponding to the predetermined set temperature and the predetermined energy saving control pattern is not stored in the room temperature estimation model database. However, the room temperature with respect to the outside air temperature can be estimated by air conditioning. Therefore, sufficient energy-saving control of the air conditioner can be performed, and it becomes easy to achieve the target power consumption.

In the air conditioning system of the present invention, the estimated room temperature calculation unit may use the room temperature in each cell when the room temperature estimation model is stored in two cells in one row or one column of the matrix of the room temperature estimation model database. The estimated room temperature for the outside temperature is calculated using the estimation model, and each estimated room temperature of each calculated cell is linearly interpolated for the outside temperature when the air conditioner is operated with a predetermined set temperature and a predetermined energy-saving control pattern. If the estimated room temperature is calculated and the room temperature estimation model is stored in three or more cells in one row or one column of the matrix of the room temperature estimation model database, the room temperature estimation model is used in each cell. The estimated room temperature with respect to the temperature is calculated, and each estimated room temperature of each calculated cell is linearly interpolated, or an approximate curve showing the change in the estimated room temperature with respect to the cell arrangement is generated by each estimated room temperature of each calculated cell. Based on the generated approximate curve, the estimated room temperature with respect to the outside temperature when the air conditioner is operated with a predetermined set temperature and a predetermined energy saving control pattern may be calculated.

When the room temperature estimation model is stored in two cells in one row or one column of the matrix of the room temperature estimation model database, the room temperature can be easily estimated by linear interpolation, and the room temperature estimation model database can be used. When the room temperature estimation model is stored in three or more cells in one row or one column of the matrix, the room temperature estimation accuracy can be improved by performing interpolation using an approximate curve.

The estimated room temperature calculation unit includes a unit and an indoor unit corresponding to a predetermined set temperature for each indoor unit and a predetermined energy-saving control pattern for each indoor unit in the room temperature estimation model database for each indoor unit of one indoor unit. When another room temperature estimation model is stored, the operation of calculating the estimated room temperature in the vicinity of one indoor unit with respect to the outside temperature using the room temperature estimation model for each indoor unit stored in the indoor unit-specific room temperature estimation model database. Is repeatedly executed for each of a plurality of indoor units to calculate each estimated room temperature in the vicinity of each indoor unit, and the predetermined set temperature for each indoor unit and the indoor unit are stored in the room temperature estimation model database for each indoor unit of one indoor unit. If the room temperature estimation model for each indoor unit that corresponds to another predetermined energy-saving control pattern is not stored, the room temperature estimation model for each indoor unit is used outside in multiple cells that store the room temperature estimation model for each indoor unit. The estimated room temperature in the vicinity of one indoor unit with respect to the air conditioner is calculated, and the estimated room temperature in the vicinity of one indoor unit in the calculated cells is interpolated to obtain a predetermined set temperature for each indoor unit and a predetermined energy saving for each indoor unit. The operation of calculating the estimated room temperature in the vicinity of one indoor unit with respect to the outside temperature when the air conditioner is operated in the control pattern is repeatedly executed for each of a plurality of indoor units to calculate each estimated room temperature in the vicinity of each indoor unit. It is characterized by that.

The heat load of the indoor unit differs depending on the place where the indoor unit is installed, for example, the window side or the aisle side. Therefore, the change in room temperature when the energy saving control of the air conditioner is executed differs for each indoor unit. The present invention stores a plurality of indoor unit-specific room temperature estimation models that estimate each room temperature in the vicinity of each indoor unit in the room temperature estimation model database, and stores a predetermined set temperature for each indoor unit and a predetermined energy-saving control pattern for each indoor unit. If the room temperature estimation model for each indoor unit corresponding to is not stored, each room temperature with respect to the outside temperature of each indoor unit is estimated by interpolation. Even if the room temperature estimation model database does not store a room temperature estimation model corresponding to a predetermined set temperature and a predetermined energy saving control pattern, each room temperature with respect to the outside temperature of each indoor unit can be estimated. As a result, the change in room temperature in the vicinity of each indoor unit is estimated when energy saving control is performed, and the target power consumption is performed while energy saving control is performed in each indoor unit so that the change in room temperature in the vicinity of each indoor unit does not become large. Will be easier to achieve.

And one row or one of the matrix of the room temperature estimation model database for each indoor unit is calculated by calculating the estimated room temperature near one indoor unit with respect to the outside temperature when the air conditioner is operated according to the predetermined energy-saving control pattern for each indoor unit. When the room temperature estimation model is stored in three or more cells in one column, the estimated room temperature near one indoor unit with respect to the outside temperature is calculated in each cell using the room temperature estimation model, and each calculated cell is calculated. An approximate curve showing the change in the estimated room temperature in the vicinity of one indoor unit with respect to the cell arrangement is obtained by linearly interpolating the estimated room temperature in the vicinity of one indoor unit or by calculating the estimated room temperature in the vicinity of one indoor unit in each cell.

Hereinafter, the air conditioning system 100 of the embodiment will be described with reference to the drawings. As shown in FIG. 1, the air conditioning system 100 of the embodiment estimates the room temperature Tr with respect to the outside temperature T0 when the air conditioner 10 and the air conditioner 10 are operated with a predetermined set temperature and a predetermined energy saving control pattern. It is composed of a device 50.

As shown in FIG. 1, the air conditioner 10 includes the first to sixth indoor units 31 to 36 arranged on the ceiling of the room 60 (see FIG. 12) of the building, which is an air-conditioned space, and the outdoor such as the roof of the building. It is composed of first and second outdoor units 21 and 22 arranged in the above, a controller 40, and a communication unit 45. In the following description, when the first to sixth indoor units are not distinguished, it is referred to as an indoor unit 30, and when the first and second outdoor units 21 and 22 are not distinguished, it is referred to as an outdoor unit 20.

The outdoor unit 20 is provided with a heat pump or the like inside, and supplies a low-temperature refrigerant for cooling or a high-temperature refrigerant for heating to the indoor unit 30. The first outdoor unit 21 is connected to the first to third indoor units 31 to 33 and supplies the refrigerant to the first to third indoor units 31 to 33. Further, the second outdoor unit 22 is connected to the fourth to sixth indoor units 34 to 36 to supply the refrigerant to the fourth to sixth indoor units 34 to 36. Each indoor unit 30 includes a heat exchanger and a fan that transfer the heat of the refrigerant to the air, exchanges heat between the refrigerant and the air in the room, and cools or heats the air-conditioned space.

Each indoor unit 30 is equipped with a room temperature sensor 37 that detects a room temperature Tr in the vicinity of each indoor unit 30. Further, each outdoor unit 20 is equipped with an outside air temperature sensor 23 that detects the outside air temperature T0. Each outdoor unit 20 and each indoor unit 30 are connected to a controller 40. Each room temperature Tr in the vicinity of each indoor unit 30 detected by the room temperature sensor 37 and the outside air temperature sensor 23 and the outside air temperature T0 in the vicinity of each outdoor unit 20 are input to the controller 40.

The controller 40 is composed of a general-purpose computer 150 (see FIG. 2) including a CPU 151 that processes information internally and a memory. The first and second outdoor units 21 and 22 and the first to sixth indoor units 31 to 31 A control unit 41 that controls the operation of the 36, and a storage unit 42 that includes an indoor unit setting database 200 that stores operation setting information of the first and second outdoor units 21 and 22 and the first to sixth indoor units 31 to 36. , It has three functional blocks with the communication unit 45. The storage unit 42 stores programs and operation data for operation control of the first and second outdoor units 21 and 22, and the first to sixth indoor units 31 to 36. Further, the communication unit 45 is connected to a communication line 48 such as a telephone line and the Internet.

As shown in FIG. 2, the general-purpose computer 150 includes a CPU 151 which is a processor that performs information processing, a ROM 152 and a RAM 153 that temporarily store data during information processing, and a hard disk drive that stores programs, user data, and the like. (HDD) 154, a mouse 155 provided as an input means, a keyboard 156, and a display 157 provided as a display device are included. The CPU 151, the ROM 152, the RAM 153, and the HDD 154 are connected by the data bus 160. Further, the mouse 155, the keyboard 156, and the display 157 are connected to the data bus 160 via the input / output interface 158. Further, a network controller 159 provided as a communication means is connected to the data bus 160.

The control unit 41 and the communication unit 45 of the controller 40 are realized by the cooperative operation of the hardware of the general-purpose computer 150 shown in FIG. 2 and the program running on the CPU 151. Further, the storage unit 42 is realized by the HDD 154 of the general-purpose computer 150 shown in FIG. Instead of HDD 154, it may be realized by using an external storage means via a network, or SDD may be used.

As shown in FIG. 3, in the indoor unit setting database 200 stored in the storage unit 42, the set temperature of each indoor unit 30, the indoor unit energy saving control pattern of each indoor unit 30, and each indoor unit 30 are connected to each other. It is stored in association with the outdoor unit energy saving pattern of the outdoor unit 20. Here, the set temperature is the control target temperature of the room temperature Tr in the vicinity of each indoor unit 30. The energy-saving control pattern of the air conditioner 10 composed of the outdoor unit 20 and the indoor unit 30 is composed of a combination of the indoor unit energy-saving control pattern of the indoor unit 30 and the outdoor unit energy-saving control pattern of the outdoor unit 20. An example of the indoor unit energy saving control pattern is blower rotation control. Blower rotation control is an operating state in which the supply of low-temperature or high-temperature refrigerant is stopped to the heat exchangers of a plurality of indoor units 30 connected to one outdoor unit 20 and only the fan is operated for a predetermined time. This is a control performed in order by a plurality of indoor units 30. The blower rotation control has a plurality of control patterns depending on how many minutes the blower operation is performed during the operation time of 30 minutes. For example, when the blower operation is performed for only 3 minutes in the 30-minute operation, the blower energy-saving control pattern of "blower rotation blower 3 minutes" is obtained. Further, when the blower operation is performed for only 6 minutes in the 30-minute operation, the blower energy-saving control pattern of "blower rotation blower 6 minutes" is adopted. In the case of normal operation in which the ventilation operation is not performed, the indoor unit energy saving control pattern of "blower rotation 0 minutes" is applied.

Further, as an example of the outdoor unit energy saving control pattern, there is a capacity saving control in which the capacity of the outdoor unit 20 is reduced and operated. In this case, the outdoor unit 20 is operated with a capacity reduced to 80% or the like, and each indoor unit 30 connected to the outdoor unit 20 is normally operated. In this case, the outdoor unit energy saving control pattern is "capacity 80%". Further, when the outdoor unit 20 does not perform energy saving control and performs normal operation, the energy saving control pattern of the air conditioner is "capacity 100%". The outdoor unit 20 may be operated at a capacity of 80%, and the indoor unit 30 may be operated under blower rotation control.

The control unit 41 of the controller 40 of the air conditioner 10 operates the outdoor unit 20 and the indoor unit 30 based on the operating conditions of the indoor unit 30 and the outdoor unit 20 stored in the indoor unit setting database 200. At this time, when both the outdoor unit 20 and the indoor unit 30 are in normal operation and the energy-saving control operation is not performed, the control unit 41 sets the room temperature Tr detected by the room temperature sensor 37 of each indoor unit 30 to the set temperature. The outdoor unit 20 and the indoor unit 30 are operated. On the other hand, when the energy saving control pattern is set for either the outdoor unit 20 or the indoor unit 30, the outdoor unit 20 and the indoor unit 30 are operated with priority given to the operation according to each energy saving control pattern. Therefore, when the energy saving control pattern is set, the room temperature Tr becomes a temperature changed from the set temperature. For example, in the case of cooling, the room temperature Tr is slightly higher than the set temperature.

The controller 40 outputs the operation record of the air conditioner 10 when the above-mentioned operation is performed from the communication unit 45 to the communication line 48. The operation record includes, for example, the date and time, the outside air temperature T0 detected by the outside air temperature sensor 23, the set temperature, the energy saving control pattern of the indoor unit 30, the outdoor unit 20, and the room temperature Tr detected by the room temperature sensor 37.

The room temperature estimation device 50 is composed of six functional blocks of a communication unit 51, a room temperature estimation model generation unit 52, an estimated room temperature calculation unit 53, a display generation unit 54, a display unit 55, and a storage unit 56. .. The outline of each functional block is as follows.

The communication unit 51 communicates with the communication line 48, receives the operation record of each indoor unit 30 of the air conditioner 10 from the controller 40 of the air conditioner 10, and stores it in the air conditioner operation record database 300 of the storage unit 56. The room temperature estimation model generation unit 52 reads out the operating state of each indoor unit 30 stored in the air conditioner operation record database 300, and calculates the room temperature Tr in the vicinity of each indoor unit 30 with respect to the outside air temperature T0. A model is generated and stored in the matrix of the room temperature estimation model database 400. The estimated room temperature calculation unit 53 calculates the room temperature in the vicinity of each indoor unit 30 by using the room temperature estimation model for each indoor unit stored in the matrix of the room temperature estimation model database 400. The display generation unit 54 superimposes the data of the estimated room temperature in the vicinity of each indoor unit 30 calculated by the estimated room temperature calculation unit 53 and the image of the air-conditioning space to generate a display image and outputs the display image to the display unit 55. The display unit 55 displays an image in which the air-conditioned space and the estimated room temperature Tr are superimposed.

Here, the communication unit 51, the room temperature estimation model generation unit 52, the estimation room temperature calculation unit 53, and the display generation unit 54 cooperate with the hardware of the general-purpose computer 150 shown in FIG. 2 and the program running on the CPU 151. Is realized by. The display unit 55 is realized by the display 157 of the general-purpose computer 150 shown in FIG. 2, and the storage unit 56 is realized by the HDD 154 of the general-purpose computer 150 shown in FIG.

The details of each functional block will be described below. As shown in FIG. 4, the air conditioner operation record database 300 stored in the storage unit 56 stores a plurality of operation record databases 301 to 303 for each indoor unit for each indoor unit. The operation record database 301 to 303 for each indoor unit includes the operation date and time, the outside air temperature T0 detected by the outside air temperature sensor 23 of the outdoor unit 20 to which the indoor unit 30 is connected, and the indoor unit 30 for each indoor unit 30. The set temperature of the indoor unit 30, the indoor unit energy saving control pattern of the indoor unit 30, the outdoor unit energy saving control putter of the outdoor unit 20 to which the indoor unit 30 is connected, and the indoor unit detected by the room temperature sensor 37 of the indoor unit 30. This is a database stored in association with the room temperature Tr in the vicinity of the machine 30.

The database structure will be described by taking the operation record database 301 for each indoor unit shown in FIG. 4 as an example. The operation record database 301 for each indoor unit is an operation record of the first indoor unit 31 having the indoor unit number 001. The outside air temperature T0 is a value detected by the outside air temperature sensor 23 attached to the first outdoor unit 21 to which the first indoor unit 31 is connected. The room temperature Tr is a value detected by the room temperature sensor 37 attached to the first indoor unit 31. The set temperature of the first indoor unit 31 is 26 ° C., which is the set temperature of the indoor unit number 001 of the indoor unit setting database 200 described above. Further, the indoor unit energy-saving control pattern of the first indoor unit 31 and the outdoor unit energy-saving control pattern of the first outdoor unit 21 are stored in the indoor unit setting database 200, respectively, as shown in "Blower rotation 6 minutes" and "Blower rotation". Ability is 100% ".

Then, as shown in FIG. 4, between 14:00 and 14:40 on August 28, 2019, the first indoor unit 31 has a set temperature of 26 ° C., and the indoor unit energy saving control pattern is "Blower rotation Blower 6 minutes." The first outdoor unit 21 is operated with the outdoor unit energy saving control pattern of "capacity 100%". During this period, the outside air temperature T0 changes between 30.0 ° C. and 33.0 ° C., and the room temperature Tr near the first indoor unit 31 changes from 26.2 ° C. to 26.5 ° C. according to the change in the outside air temperature T0. Varies between ° C. Since the first indoor unit 31 is operated under energy saving control, the controller 40 of the air conditioner 10 gives priority to the energy saving control pattern of the first indoor unit 31 without controlling the room temperature Tr to the set temperature, and gives priority to the energy saving control pattern of the first indoor unit 31. Drive the machine 31. Therefore, the room temperature Tr is slightly higher than the set temperature of 26 ° C.

Similarly, the indoor unit-specific operation record database 302 stores the operating state of the second indoor unit 32 having the indoor unit number 002 and the change in the room temperature Tr with respect to the outside air temperature T0. Like the first indoor unit 31, the second indoor unit 32 is also operated in the energy saving control pattern of "blower rotation 6 minutes". However, as shown in FIG. 12, since the second indoor unit 32 is arranged at a position close to the window 61 of the room 60, the room temperature Tr in the vicinity of the second indoor unit 32 has the same “blower rotation 6 minutes”. It is operated in the energy saving control pattern and is slightly higher than the room temperature Tr in the vicinity of the first indoor unit 31.

The communication unit 51 outputs these data acquired from the controller 40 of the air conditioner 10 via the communication line 48 to the air conditioner operation record database 300, and stores the data in the air conditioner operation record database 300.

As described above, the room temperature estimation model generation unit 52 reads out the operating states of the indoor units 30 and the outdoor units 20 stored in the air conditioner operation record database 300, and reads the operating states of the indoor units 30 with respect to the outside air temperature T0. A room temperature estimation model for each indoor unit that calculates the room temperature Tr in the vicinity is generated and stored in the matrix of the room temperature estimation model database 400.

Hereinafter, as an example, the room temperature estimation model generation unit 52 determines the room temperature Tr in the vicinity of the first indoor unit 31 with respect to the outside air temperature T0 based on the operation record of the first indoor unit 31 stored in the indoor unit-specific operation record database 301. A case of generating a room temperature estimation model for calculating the above will be described.

（式１）の傾きＡと切片Ｂとは、例えば、室内機別運転記録データベース３０１に格納された第１室内機３１の運転記録の外気温Ｔ０と室温Ｔｒのデータを線形回帰により求めることができる。室温Ｔｒと外気温Ｔ０との関係は、第１室内機３１の設定温度、室内機省エネ制御パターン、室外機省エネ制御パターンによって変化する。従って、室温推定モデル生成部５２は、室内機別運転記録データベース３０１に基づいて、第１室内機３１の設定温度が２６℃、室内機省エネ制御パターンが「送風ローテーション 送風６分」、室外機省エネ制御パターンが「能力１００％」の条件で第１室内機３１と第１室外機２１とを運転した際の外気温Ｔ０に対する室温Ｔｒを推定する（式１）の傾きＡ，切片Ｂを線形回帰により生成し、推定式を生成する。生成した室温Ｔｒの推定式は、図５に示す室温推定モデルデータベース４００に格納される。 The room temperature Tr in the vicinity of the first indoor unit 31 can be expressed as the following (Equation 1) as a function of the outside air temperature T0.

For the slope A and the intercept B of (Equation 1), for example, the data of the outside air temperature T0 and the room temperature Tr of the operation record of the first indoor unit 31 stored in the indoor unit operation record database 301 can be obtained by linear regression. can. The relationship between the room temperature Tr and the outside air temperature T0 changes depending on the set temperature of the first indoor unit 31, the indoor unit energy saving control pattern, and the outdoor unit energy saving control pattern. Therefore, the room temperature estimation model generation unit 52 sets the temperature of the first indoor unit 31 to 26 ° C., the indoor unit energy saving control pattern is "blower rotation 6 minutes", and the outdoor unit energy saving is based on the indoor unit operation record database 301. Linear regression of slope A and intercept B of (Equation 1) for estimating room temperature Tr with respect to outside air temperature T0 when the first indoor unit 31 and the first outdoor unit 21 are operated under the condition that the control pattern is "capacity 100%". To generate an estimation formula. The generated room temperature Tr estimation formula is stored in the room temperature estimation model database 400 shown in FIG.

As shown in FIG. 5, the room temperature estimation model database 400 stores a plurality of matrices constituting the room temperature estimation model databases 401 to 404 for each indoor unit. Hereinafter, the room temperature estimation model database 401 for each indoor unit will be described as an example with reference to FIG. Although not shown in FIG. 5, the room temperature estimation model database 400 stores at least one room temperature estimation model database for each of the first to sixth indoor units 31 to 36.

FIG. 5 shows a room temperature estimation model that estimates the room temperature Tr with respect to the outside air temperature T0 when the first indoor unit 31 and the first outdoor unit 21 are operated under the condition that the outdoor unit energy saving control pattern is "capacity 90%". It is stored as "g123 (T0)" in 2 rows and 3 columns of the room temperature estimation model database 404 for each indoor unit shown. Here, the alphabet "g" indicates an energy-saving control pattern in which the outdoor unit 20 performs a capacity reduction operation.

As described above, the room temperature estimation model generation unit 52 reads out the operating states of the indoor units 30 and the outdoor units 20 stored in the air conditioner operation record database 300 shown in FIG. 4, and reads out the operating states of each indoor unit 20 with respect to the outside air temperature T0. A room temperature estimation model for each indoor unit that calculates the room temperature Tr in the vicinity of the machine 30 is generated and stored in the matrix of the room temperature estimation model databases 401 to 404 for each indoor unit of the room temperature estimation model database 400. However, as in the case where the set temperature of 1 row and 2 columns of the room temperature estimation model database 401 for each indoor unit shown in FIG. 5 is 25 ° C. and the indoor unit energy saving control pattern is "blower rotation blower 3 minutes", the operation has no operation record. The room temperature estimation model is not stored in the condition cell.

Next, the operation of the estimated room temperature calculation unit 53 will be described with reference to FIGS. 7 to 11.
Hereinafter, it is assumed that the room temperature estimation model database 400 stores the room temperature estimation model database 410 for each indoor unit shown in FIG. As shown in FIG. 8, the room temperature estimation model database 410 for each indoor unit operates the first outdoor unit 21 connected to the first indoor unit 31 at a capacity of 100%, and the first indoor unit 31 in 2 rows and 1 column. The room temperature estimation model for calculating the room temperature Tr with respect to the outside air temperature T0 when the set temperature of is 26 ° C. and the indoor unit energy saving control pattern is "blower rotation blower 0 minutes" is stored as "f121 (T0)". In addition, in 2 rows and 3 columns, a room temperature estimation model that calculates the room temperature Tr with respect to the outside air temperature T0 when the set temperature of the first indoor unit 31 is 26 ° C. and the indoor unit energy saving control pattern is "blower rotation blower 6 minutes". Is stored as "f123 (T0)". Further, in 1 row 5 columns and 3 rows 5 columns, the indoor unit energy saving control pattern of the first indoor unit 31 is set to "blower rotation blower 15 minutes", and the outside air temperature is set to 25 ° C and 27 ° C, respectively. The room temperature estimation models for calculating the room temperature Tr with respect to T0 are stored as "f115 (T0)" and "f135 (T0)", respectively. The room temperature estimation model for each indoor unit is not stored in the other cells of the database 410.

As shown in step S101 of FIG. 7, the estimated room temperature calculation unit 53 specifies the calculation conditions for calculating the estimated room temperature, that is, the identification of the indoor unit 30, the set temperature of the indoor unit 30, and the indoor unit 30. The machine energy saving control pattern and the outdoor unit energy saving control pattern of the outdoor unit 20 connected to the indoor unit 30 are set. Then, the process proceeds to step S102, and it is confirmed whether or not the room temperature estimation model that matches the set calculation conditions is stored in the room temperature estimation model database 410 for each indoor unit.

For example, operating the first indoor unit 31 at a set temperature of 26 ° C. and “blowing rotation 0 minutes” and operating the first outdoor unit 21 connected to the first indoor unit 31 at a capacity of 100% is a room temperature Tr. When set to the calculation condition of, this calculation condition is stored as the room temperature estimation model "f121 (T0)" in 2 rows and 1 column of the room temperature estimation model database 410 for each indoor unit shown in FIG. In this case, the estimated room temperature calculation unit 53 determines YES in step S102 of FIG. 7, and proceeds to step S103 of FIG. In step S103 of FIG. 7, the estimated room temperature calculation unit 53 inputs the outside air temperature T0 to the room temperature estimation model “f121 (T0)” to perform the first indoor unit 31 and the first outdoor unit 21 under the set calculation conditions. The room temperature in the vicinity of the first indoor unit 31 with respect to the outside air temperature T0 during operation is calculated as "T121 (T0)" and stored in the room temperature matrix 510 shown in FIG. Here, the room temperature matrix 510 has the same matrix structure as the room temperature estimation model database 410 for each indoor unit, and the estimated room temperature calculation unit 53 sets the calculated room temperature “T121 (T0)” at the same matrix position of the room temperature matrix 510. Store in cells with 2 rows and 1 column.

Similarly, when the set temperature of the first indoor unit 31 is set to 26 ° C. and the indoor unit energy saving control pattern is set to "blower rotation 6 minutes" as the calculation condition, the indoor unit energy saving control pattern of the first indoor unit 31 is set to "blower". Even when the set temperature is set to 25 ° C and 27 ° C as the calculation conditions, the room temperature estimation model corresponding to each calculation condition is the room temperature estimation model database 410 for each indoor unit shown in FIG. The room temperature estimation models "f123 (T0)", "f115 (T0)", and "f135 (T0)" are stored in 2 rows and 3 columns, 1 row and 5 columns, and 3 rows and 5 columns. Therefore, the estimated room temperature calculation unit 53 determines YES in step S102 of FIG. 7, proceeds to step S103 of FIG. 7, and proceeds to the room temperature estimation models “f123 (T0)”, “f115 (T0)”, and “f135 (T0)”. By inputting the outside air temperature T0 to ")", the room temperature in the vicinity of the first indoor unit 31 with respect to the outside air temperature T0 when the first indoor unit 31 and the first outdoor unit 21 are operated under the set calculation conditions, respectively. It is calculated as "T123 (T0)", "T115 (T0)", and "T135 (T0)". Then, the estimated room temperature calculation unit 53 stores the calculated room temperatures “T123 (T0)”, “T115 (T0)”, and “T135 (T0)” in the same matrix position cell of the room temperature matrix 510.

Then, the estimated room temperature calculation unit 53 outputs the calculated room temperature “T121 (T0)”, “T123 (T0)”, “T115 (T0)”, and “T135 (T0)” to the display generation unit 54. In step S107 of FIG. 7, the display generation unit 54 calculates the room temperature Tr calculated by the estimated room temperature calculation unit 53 on the arrangement image of the indoor unit 30 or the desk in the room of the building stored in the air-conditioning space arrangement database 600. To generate a display side image by superimposing the above, and display it on the display unit 55.

On the other hand, in FIG. 8, when the set temperature of the first indoor unit 31 is 26 ° C., the indoor unit energy-saving control pattern corresponds to "blower rotation blower 3 minutes", "blower rotation blower 9 minutes", or "blower rotation blower 15 minutes". The room temperature estimation model is not stored in the cells of 2 rows and 2 columns, 2 rows and 4 columns, and 2 rows and 5 columns. Therefore, when such a calculation condition is set, the estimated room temperature calculation unit 53 determines NO in step S102 of FIG. 7, proceeds to step S104 of FIG. 7, and first under the calculation condition set by interpolation. It is determined whether or not the room temperature Tr can be estimated and calculated when the indoor unit 31 and the first outdoor unit 21 are operated.

In step S104 of FIG. 7, the estimated room temperature calculation unit 53 determines whether the room temperature estimation model is stored in two or more cells in one row or one column of the matrix in the room temperature estimation model database 410 for each indoor unit. do. As shown in FIG. 8, in the second row of the room temperature estimation model database 410 for each indoor unit, the room temperature estimation model is stored in two cells of 2 rows 1 column and 2 rows 3 columns, and the room temperature estimation model is stored in the 5th column. The room temperature estimation model is stored in two cells, 1 row and 5 columns and 3 rows and 5 columns. Therefore, the estimated room temperature calculation unit 53 determines YES in step S104 of FIG. 7, proceeds to step S105 of FIG. 7, and among the plurality of cells in which the room temperature estimation model is stored, the room temperature is close to the calculation condition. The estimated room temperature with respect to the outside air temperature T0 is calculated using the estimation model. If the estimated room temperature calculation unit 53 determines NO in step S104 of FIG. 7, the estimated room temperature calculation process ends.

In step S105 of FIG. 7, the estimated room temperature calculation unit 53 sets the set temperature of the first indoor unit 31 to 26 ° C., and sets the indoor unit energy-saving control pattern to the room temperature of the cells in 2 rows and 2 columns corresponding to “blower rotation 3 minutes”. When trying to estimate "T122 (T0)", or when trying to estimate the room temperature "T124 (T0)" of the cell of 2 rows and 4 columns corresponding to "blower rotation 9 minutes", FIG. As shown in the above, the room temperature estimation model "f121 (T0)" of the adjacent 2 rows and 1 column "blower rotation 0 minutes" and the 2 rows and 3 columns "blower" differing only in the indoor unit energy saving control pattern under the same conditions. Using the room temperature estimation model "f123 (T0)" of "rotation blast 6 minutes", outside the case of "blower rotation 0 minutes" in 2 rows and 1 column and the case of "blower rotation 0 minutes" in 2 rows and 1 column. The estimated room temperatures "T121 (T0)" and "T123 (T0)" with respect to the air temperature T0 are calculated. Then, the estimated room temperature calculation unit 53 stores the calculated estimated room temperature in cells at the same matrix position of the room temperature matrix 510 having the same matrix structure as the room temperature estimation model database 410 for each indoor unit.

Then, the estimated room temperature calculation unit 53 proceeds to step S106 of FIG. 7 and interpolates the calculated 2-row 1-column estimated room temperature "T121 (T0)" and the 2-row 3-column cell estimated room temperature "T123 (T0)". Then, the room temperature "T122 (T0)" with respect to the outside air temperature T0 of the cell of 2 rows and 2 columns and the room temperature "T124 (T0)" with respect to the outside air temperature T0 of the cell of 2 rows and 4 columns are calculated.

The room temperature "T122 (T0)" and "T124 (T0)" are calculated by regarding the room temperature matrix 510 as a Cartesian coordinate system and using one cell of the room temperature matrix 510 as a unit distance, and each estimated room temperature "T121" of the plurality of cells calculated. (T0) ”and“ T123 (T0) ”are interpolated and calculated.

Since one cell of the room temperature matrix 510 is used as the unit distance, as shown in FIG. 9, the distance d1 between the cell of the room temperature matrix 510 in 2 rows and 1 column and the cell of 2 rows and 2 columns is 1, and 2 of the room temperature matrix 510. The distance d2 between the cells in rows and 2 columns and the cells in rows and 3 columns is also 1. Then, the room temperature "T122 (T0)" with respect to the outside air temperature T0 of the cells in 2 rows and 2 columns is calculated by an interpolation interpolation formula as shown in (Equation 2) below.

Further, the distance d4 between the cells in 2 rows and 1 column of the room temperature matrix 510 and the cells in 2 rows and 4 columns is 3, and the distance d3 between the cells in 2 rows and 3 columns and the cells in 2 rows and 4 columns in the room temperature matrix 510 is 1. It becomes. Then, the room temperature "T124 (T0)" with respect to the outside air temperature T0 of the cells in 2 rows and 4 columns is calculated by an extrapolation equation as in (Equation 3) below.

Similarly, the estimated room temperature calculation unit 53 sets the set temperature of the first indoor unit 31 to 26 ° C., and sets the indoor unit energy saving control pattern to the room temperature “T125 (T0)” of the cells in 2 rows and 5 columns corresponding to “blower rotation blower 15 minutes”. ) ”, Or when trying to estimate the room temperature“ T145 (T0) ”of a cell in 4 rows and 5 columns corresponding to the set temperature of 28 ° C and the indoor unit energy saving control pattern of“ blast rotation blast 15 minutes ”, it is adjacent. Room temperature estimation model "f115 (T0)" with 2 rows and 5 columns set temperature 25 ° C and "blower rotation 15 minutes" and room temperature estimation model with 3 rows and 5 columns set temperature 27 ° C and "blower rotation 15 minutes" Using "f135 (T0)", the set temperature of 1 row and 5 columns is 25 ° C, and the set temperature of "blower rotation blower 15 minutes" and the set temperature of 3 rows and 5 columns is 27 ° C, "blower rotation blower 15 minutes". The estimated room temperatures "T115 (T0)" and "T135 (T0)" with respect to the outside temperature T0 are calculated. Then, the calculated estimated room temperatures "T115 (T0)" and "T135 (T0)" are stored in the same cell of the room temperature matrix 510.

As described above for the columns, one cell of the room temperature matrix 510 is used as the unit distance. Therefore, as shown in FIG. 9, the distance e1 between the cells of the room temperature matrix 510 in 1 row and 5 columns and the cells in 2 rows and 5 columns. Is 1, and the distance e2 between the cell of 2 rows and 5 columns and the cell of 3 rows and 5 columns of the room temperature matrix 510 is also 1. Then, the room temperature "T125 (T0)" with respect to the outside air temperature T0 of the cells in 2 rows and 5 columns is calculated by an interpolation interpolation formula as shown in (Equation 4) below.

It becomes. Then, the room temperature "T145 (T0)" with respect to the outside air temperature T0 of the cells in 4 rows and 5 columns is calculated by an extrapolation equation as shown in (Equation 5) below.

Then, the estimated room temperature calculation unit 53 stores the calculated estimated room temperatures “T125 (T0)” and “T145 (T0)” in the same cell of the room temperature matrix 510.

Then, the estimated room temperature calculation unit 53 calculates the estimated room temperature "T121 (T0)", "T122 (T0)", "T123 (T0)", "T124 (T0)", "T125 (T0)", "T115". (T0) ”,“ T135 (T0) ”, and“ T145 (T0) ”are output to the display generation unit 54. In step S107 of FIG. 7, the display generation unit 54 estimates each estimation calculated by the room temperature calculation unit 53 on the arrangement image of the indoor unit 30, the desk, etc. in the room of the building stored in the air-conditioning space arrangement database 600. A display side image is generated by superimposing the room temperature and displayed on the display unit 55.

As described above, in the vicinity of the first indoor unit 31 when the first indoor unit 31 is operated with a predetermined set temperature and a predetermined indoor unit energy saving control pattern and the first outdoor unit 21 is operated with a predetermined outdoor unit energy saving control pattern. Although the estimation of the room temperature Tr has been described, the estimated room temperature calculation unit 53 also executes steps S101 to S107 of FIG. 7 for the second indoor unit 32 to the sixth indoor unit 36 to execute the second indoor unit 32 to the second indoor unit 32 to the third. 6 The second indoor unit 32 when the indoor unit 36 is operated with a predetermined set temperature and a predetermined indoor unit energy saving control pattern, and the first outdoor unit 21 and the second outdoor unit 22 are operated with the predetermined outdoor unit energy saving control putter. ~ Each room temperature Tr in the vicinity of the sixth indoor unit 36 can be estimated.

Then, in step S107 of FIG. 7, as shown in FIG. 12, each room temperature is arranged in the arrangement of the first to sixth indoor units 31 to 36 arranged in the room 60 of the building in the air-conditioned space, and the arrangement of the windows 61 and the desk 63. An image is generated by superimposing the display 64, and an image as shown in FIG. 12 is displayed on the display unit 55. Thereby, it is possible to display the distribution of the room temperature Tr in the vicinity of the first to sixth indoor units 31 to 36 with respect to the outside air temperature T0 when the air conditioner 10 is operated at a predetermined set temperature and a predetermined energy saving control pattern. As a result, the distribution of each room temperature Tr in the vicinity of the first to sixth indoor units 31 to 36 in the air-conditioned space can be visually recognized, and the energy saving control pattern of the first to sixth indoor units 31 to 36 can be adjusted. It becomes easy to do.

Further, as shown in FIG. 12, a bar 65 capable of changing the outside air temperature T0 to be calculated is displayed on the display unit 55, and the cursor 66 of the bar 65 is moved by the mouse 155 shown in FIG. The temperature T0 may be changed. As a result, it is possible to visually grasp the change of each room temperature Tr when the outside air temperature T0 changes while looking at the screen, and it is possible to easily adjust the energy saving control pattern of the first to sixth indoor units 31 to 36. can.

The heat load of the first to sixth indoor units 31 to 36 differs depending on the place where the first to sixth indoor units 31 to 36 are installed, for example, the window side or the aisle side. Therefore, the change in room temperature when the energy saving control of the air conditioner 10 is executed differs between the first to sixth indoor units 31 to 36, respectively. In the air conditioning system 100 of the embodiment, a plurality of room temperature estimation model databases 401 to 404 for estimating each room temperature Tr in the vicinity of each indoor unit 30 are stored in the room temperature estimation model database 400, and predetermined settings for each indoor unit are set. If the room temperature estimation model for each indoor unit corresponding to the temperature and the predetermined energy-saving control pattern for each indoor unit is not stored, each room temperature Tr for the outside temperature T0 of each indoor unit 30 is estimated by interpolation, so that a predetermined setting is made. Even if there is no operation record of the air conditioner 10 with the temperature and the predetermined energy saving control pattern and the room temperature estimation model corresponding to the predetermined set temperature and the predetermined energy saving control pattern is not stored in the room temperature estimation model database 400, each room Each room temperature Tr with respect to the outside temperature T0 of the machine 30 can be estimated. Thereby, the change of the room temperature Tr in the vicinity of each indoor unit 30 is estimated when the energy saving control is performed, and the energy saving control of each indoor unit 30 is performed so that the change of each room temperature Tr in the vicinity of each indoor unit 30 does not become large. It becomes easy to achieve the target power consumption while doing so.

In the above description, as shown in FIG. 8, in the second row of the matrix of the indoor unit-specific room temperature estimation model database 410, the cells in which the indoor unit-specific room temperature estimation model is stored are 2 rows, 1 column, and 2 rows. There are two cells in three columns, and in the fifth column, there are two cells in which the room temperature estimation model for each indoor unit is stored: 1 row and 5 columns and 3 rows and 5 columns. Therefore, when estimating the room temperature of a cell in which the room temperature estimation model for each indoor unit is not stored, two rows are used using the calculated room temperatures "T121 (T0)" and "T123 (T0)" of these two cells. Linear interpolation was performed in 5 columns using "T115 (T0)" and "T135 (T0)". That is, when the room temperature estimation model for each indoor unit is stored in two cells in one row or one column of the matrix of the room temperature estimation model database 410 for each indoor unit, each cell in which the room temperature estimation model is stored. The estimated room temperature of the cell in which the room temperature estimation model for each indoor unit is not stored was calculated by linear interpolation using the estimated room temperature calculated in.

However, as described below, if the room temperature estimation model for each indoor unit is stored in three or more cells in one row or one column of the matrix of the indoor unit room temperature estimation model database 410, this may be the case. Not limited to.

For example, as in the room temperature estimation model database 420 for each indoor unit shown in FIG. 10, the cells in the second row in which the room temperature estimation model for each indoor unit is stored are 2 rows, 1 column, 2 rows, 3 columns, and 2 rows. There are three in five columns, and in the third column, there are three cells in which the room temperature estimation model for each indoor unit is stored: 1 row 3 columns, 2 rows 3 columns, and 4 rows 3 columns. , (Equation 6) and (Equation 7) below generate an approximate curve showing the change in the estimated room temperature Tr with respect to the cell arrangement, and based on the generated approximate curve, the predetermined set temperature for each indoor unit and the room. The estimated room temperature Tr in the vicinity of the indoor unit 30 with respect to the outside temperature T0 when the air conditioner 10 is operated according to a predetermined energy-saving control pattern for each unit may be calculated.

（式６）、（式７）おいて、ｎ、ｍはそれぞれ列番号、行番号を示す。

In (Equation 6) and (Equation 7), n and m indicate column numbers and row numbers, respectively.

In this case, as shown in FIG. 10 in step S105 of FIG. 7, the estimated room temperature calculation unit 53 has 2 rows 1 column, 2 rows 3 columns, 2 rows 5 columns, 1 row 3 of the room temperature estimation model database 420 for each indoor unit. Room temperature estimation models "f121 (T0)", "f123 (T0)", "f125 (T0)", "f113 (T0)", "f143 (T0)" stored in columns, 4 rows and 3 columns, respectively. ) ”Is used to calculate the estimated room temperature“ T121 (T0) ”,“ T123 (T0) ”,“ T125 (T0) ”,“ T113 (T0) ”,“ T143 (T0) ”of each cell, and FIG. Store in cells at the same matrix position in the room temperature matrix 520 shown in.

Then, in step S106 of FIG. 7, the estimated room temperature calculation unit 53 performs the estimated room temperature “T121 (T0)” and “T123 (T01)” of each cell of the room temperature matrix 520 in 2 rows and 1 column, 2 rows and 3 columns, and 2 rows and 5 columns. Based on "T0)" and "T125 (T0)", an approximate curve showing the change in the estimated room temperature Tr with respect to the arrangement of the cell rows is generated as in (Equation 6). Then, as shown in FIG. 11, 2 is substituted for n in (Equation 6) to calculate the estimated room temperature “T122T0” of the cell in 2 rows and 2 columns, and 4 is substituted for n to estimate 2 rows and 4 columns. The room temperature "T124 (T0)" is calculated and stored in the room temperature matrix 520.

Further, in step S106 of FIG. 7, the estimated room temperature calculation unit 53 determines the estimated room temperature “T113 (T0)”, “T123 (T0)” of each cell of 1 row 3 columns, 2 rows 3 columns, 4 rows 3 columns. Based on "T143 (T0)", an approximate curve showing the change in the estimated room temperature Tr with respect to the row arrangement of the cells is generated as in (Equation 7). Then, as shown in FIG. 11, 3 is substituted for m in (Equation 7) to calculate the estimated room temperature "T133T0" of the cell in 3 rows and 3 columns, and 5 is substituted for n to estimate 5 rows and 3 columns. The room temperature "T1535 (T0)" is calculated and stored in the room temperature matrix 520.

In this way, when the room temperature estimation model for each indoor unit is stored in three or more cells in one row or one column of the matrix of the room temperature estimation model database 420 for each indoor unit, interpolation by an approximate curve is performed. Thereby, the estimation accuracy of the room temperature Tr can be improved.

As described above, when the room temperature estimation model for indoor units is stored in three or more cells in one row or one column of the matrix of the indoor unit room temperature estimation model database 420, the interpolation by the approximate curve is performed. Although described, the present invention is not limited to this, and as described above with reference to FIGS. 8 and 9, in three or more cells in one row or one column of the matrix of the room temperature estimation model database 420 for each indoor unit. Even if the room temperature estimation model for each indoor unit is stored, the cell estimation for which the room temperature estimation model for each indoor unit is not stored is estimated by linear interpolation using each estimated room temperature calculated for each cell in which the room temperature estimation model is stored. Room temperature may be calculated.

In the air conditioning system 100 described above, the air conditioner 10 has been described as being composed of two first and second outdoor units 21 and 22 and six first to sixth indoor units 31 to 36. The machine 10 may be composed of one outdoor unit 20 and one indoor unit 30.

The air-conditioning system 100 described above does not have an operation record of the air conditioner 10 with a predetermined set temperature and a predetermined energy-saving control pattern, and the room temperature estimation model database 400 corresponds to a predetermined set temperature and a predetermined energy-saving control pattern.
